Full textAbstract:
Bibliographic citations are an essential component of scientific-publication digital libraries. Studies about bibliographic citations can lead to interesting results about the coverage of topics, tendencies, quality and impact of publications of a specific sub-community or individuals, patterns of collaboration in social networks, etc. However, it is usual to find ambiguous author names in bibliographic citations due to authors referenced by multiple name variations (synonyms) or when two or more authors have exactly the same name or share a same name variation (polysems). This can lead to an incorrect assignment of a citation to an author, or the separation of several citations of the same author as if they belong to different authors. Supervised methods that exploit training examples in order to distinguish ambiguous author names are among the most effective solutions for the problem, but they require skilled human annotators in a laborious and continuous process of manually labeling citations in order to provide enough training examples. In this thesis, we describe a new three-step disambiguation method, SAND (standing for Self-training Associative Name Disambiguator). SAND eliminates the need of any manual labeling effort by automatically acquiring examples using a clustering method that groups citation records based on the similarity among coauthor names. SAND also is able to detect unseen authors not included in any of the given training examples. Experiments conducted with standard public collections, using the minimum set of attributes present in a citation (i.e., author names, work title and publication venue), demonstrated that our proposed method outperforms representative unsupervised disambiguation methods that exploit similarities between citation records and is as effective as, and in some cases superior to, supervised ones, without manually labeling any training example. In order to facilitate the evaluation of name disambiguation methods in various realistic scenarios and under controlled conditions, we here propose SyGAR, a new Synthetic Generator of Authorship Records that generates citation records based on author profiles. SyGAR can be used to generate successive loads of citation records simulating a living digital library that evolves according to various desired patterns. We validate SyGAR by comparing the results produced by three representative name disambiguation methods on real as well as synthetically generated collections of citation records. We also demonstrate its applicability by evaluating those methods on a time evolving digital library collection, considering several dynamic and realistic scenarios.Bibliographic citations are an essential component of scientific-publication digital libraries.

Full textAbstract:
Citation, an essential feature of academic writing, is a challenging area for second language (L2) student writers due to its linguistic and functional complexities. In an effort to address this challenge, I report the development and evaluation of a MOODLE-based self-access workshop on citation learning, Cite Like an Academic (CLA).
CLA aims to enhance the understanding of citation use among postgraduate students in education. It employs a design-based research approach characterized by three iterative phases involving needs analysis, pedagogical design, and evaluation of an online learning artefact for increased understanding to guide further improvements (Phillips, McNaught, & Kennedy, 2012).
For the first-phase needs analysis research, I investigated the rhetorical functions of citations across various research article (RA) sections and their linguistic features. To this end, genre and corpus approaches were integrated to compare an expert corpus of research articles (the RAC) and a student corpus of master’s in education (MEd) dissertations (the MDC). The findings indicate that (1) all the RA Introduction-Methods-Results-Discussion (IMRD) sections contained citations fulfilling a wide range of rhetorical functions, and (2) RAC writers differed from MDC writers in their preference for citation types across sections, citation density across sections, reporting verb (RV) categories, RV lexico-grammatical patterns, and RV rhetorical functions. Alongside this investigation on citation use, I interviewed postgraduate students and communicated via email with supervisors to understand the needs of potential workshop participants.
The second phase, the CLA pedagogy design, was guided by the adapted critical pragmatic approach (Harwood & Hadley, 2004) with adaption. Following the pragmatic approach, instruction materials were informed by the needs analysis research findings. The critical approach involved the participants in trying out genre analysis and corpus analysis of RAs they selected for citation learning.
The third phase was the evaluation of the workshop through a user walk-through trial and three rounds of implementations. Various types of data were collected from 41 participants, including personal communications, MOODLE records of forum discussions and log reports, participants’ writing, interviews, and pre-CLA and post-CLA questionnaires.
I report the findings on the effects of genre-based materials on thesis revision, as well as students’ gains and difficulties in carrying out genre analysis and building and using their I-Corpus for citation learning. The findings indicate that content familiarity and peer interaction contributed to learners’ in-depth genre analysis; however, Move interpretation needed attention in students’ learning of genre analysis. Genre familiarity and completed writing ready for revision facilitated learners’ direct use of genre-based materials in writing, and building an individual corpus of RA part genres raised learners’ awareness of the variations in RA macro-structures. In addition, the findings demonstrate that students needed training on formulating search terms for citation searches and using corpus analytic software for corpus data observation and interpretation. In particular, students should be reminded of the disciplinary context and textual context when reusing language data from a corpus in writing revision. Finally, I provide suggestions for how to improve and adapt the workshop to support students’ citation learning and accommodate their different learning needs.published_or_final_version

Full textAbstract:
This bibliometric study examined 19,385 citations in the bibliographies, book reviews, and reading lists of 70 volumes of Adult Education Quarterly, Adult Education, Adult Education Bulletin, Adult Education Journal, and Journal of Adult Education, and 13 volumes of the Handbook of Adult Education in the United States to identify books published before 1960 which have been frequently cited before and
after 1960. Through citation analysis, an initial list of 434 titles was reduced to a core list of 64 books cited five times or more during the years between 1934 and 1988. For the purposes of this study, numbers of citations were taken to mean importance of works by indicating usefulness to subsequent authors. Of the 64 books, 55 had received at least one citation before 1960 and 57 had received at least one citation after 1960. While not all 64 of the core works constitute what might be called "classic works," it is suggested that classic works are likely to be found within the listed works.

Greenberg, Special Projects Librarian, Cushing/Whitney Medical Library, Yale University Length of presentation: 20 minutes Objective: Citation Management (CM) tools for scholarly writing predate the web browser. The advantages of current cloud-based tools, either free or subscription, support the expectation that every academic candidate for an advanced degree has an opportunity to use CM tools. CM improves the efficiency of scholarly writing and improves the formatted appearance of the electronic thesis or dissertation (ETD). The expanding range of desktop and cloud-based CM alternatives may demand student attention and potentially detract from the completion process. Do universities with ETD programs use their academic libraries to support the CM selection process, or do universities limit choices? How have universities supporting ETDs reacted to the emergence of new credible CM applications that offer attractive options for certain disciplines or devices? Methods: A brief survey was distributed to the ETD support community and social networks to ascertain the impact of burgeoning choices in CM for both students and the ETD administrative staff.

Full textAbstract:
Adult education has long been described as an emerging discipline, but there has been little empirical study of its emergence. This study examined 'emergence' by monitoring that particular knowledge base which is unique to adult education. Studies concerned with the theory and practice of adult education are a quantifiable indicator of unique knowledge about adult education. Evidence that researchers in adult education increasingly cite the work of other researchers in adult education would support the contention that the body of knowledge in adult education is growing.
The articles published in Adult Education Quarterly between 1971 and 1986 were analyzed using citation analysis methodology. The frequency of citation to previous adult education studies (primary literature) as opposed to citation of studies peripheral to an adult education context (secondary literature) was determined. Distinguishing between citation categories was carried out by analyzing each title cited. The phenomenon of concern in the cited article was interpreted from the words used in the title, and coded dichotomously as 'primary literature' or 'secondary literature'. Each coded item was then recorded under named authors; thus, the cited author was credited for total frequency cited along with the coded category of writing (author of primary literature or author of secondary literature). Reliability measures performed for intra-judge consistency (recoding data), and inter-judge agreement (independent coding of data) resulted in differences in coding of less than four percent for the former, and nine percent with the latter. Validity of the procedures used in coding cited authors was tested by comparing results obtained to a 'standard'. 'Independent experts' were asked to identify from a list of the twenty most cited authors from each four volume period, those who were "primarily known for their adult education activities." The study's coding outcome of these authors compared with the expert's 'standard' resulted in greater than 75 percent agreement.
With 4700 citations classified, it was found that a rising percentage of citations were to the "authors of primary literature"; from 41 percent of all citations in the first half of the study period (1971-1978), to 46 percent in the last half (1979-1986). A further breakdown showed the percentage of citations to "primary literature journals" also increasing; from 31 percent of all journals cited in '1971-1978' to 39 percent in '1979-1986'. As the scope of literature analyzed was exclusively from one North American journal, results need to be regarded with this limitation in mind. However, the empirical evidence of an increasing 'primary literature' base in adult education research suggests emergence of the field. Implications for future research are discussed in light of this and previous studies.Education, Faculty of

Full textAbstract:
The ongoing debate on the evaluative role of citation analysis and the theory of citation recognizes that the citation process is complex and that citation counts are affected by certain extra-scientific or external factors. To date, little effort has been made to explore the effects of various external factors; this thesis addresses this lack. In the context of the various perspectives on citations and citation analysis, this study uses journals as the unit of analysis and investigates what, how, and to what extent extra-scientific factors influence the citation impact of journals. An integrated conceptual model of Journal Citation Impact that takes into account current theoretical positions and prior empirical research findings is developed. It addresses the interrelationships between Journal Citation Impact and a range of external factors (Journal Properties, Journal Visibility, Journal Accessibility, Journal Internationality, Journal Selectivity, Journal Promptness, Journal Editorial Prestige, and Perceived Journal Quality). The proposed conceptual model is novel in that it: (1) incorporates nearly all possible external factors that affect Journal Citation Impact; (2) addresses the complex interrelationships between a number of external factors and Journal Citation Impact in one model; (3) regards both Journal Citation Impact and its external factors as theoretical constructs; and (4) identifies the observed variables of the external factors and Journal Citation Impact. However, because of the difficulties in operationalizing all the theoretical constructs, this conceptual model is simplified to an operational model for empirical testing. The operational model includes the construct Journal Citation Impact and four of its external factors, Journal Properties, Journal Accessibility, Journal Internationality, and Perceived Journal Quality. Structural Equation Modeling (SEM) with Partial Least Squares (PLS) is used to test the operational model with empirical data from 41 research journals in clinical neurology. Data are collected from bibliographic database searching, web searching, printed journals, and from a web-based survey that was conducted to obtain information on perceptions of journal quality. Empirical results of the operational model show that Journal Accessibility, Journal Internationality, and Perceived Journal Quality have large, medium, and small effects respectively on Journal Citation Impact, thus indicating that certain extra-scientific factors can influence Journal Citation Impact significantly. The findings suggest that great care should be taken in interpreting and evaluating the results obtained from citation analysis. In terms of Journal Citation Impact, this research also suggests that various journal citation indicators should be ii used to reflect different aspects of citation impact. By exploring the phenomenological domain in the citing process, this exploratory study not only provides a better understanding of citation analysis, it also contributes to the development of the theory of citation. From the methodological perspective, introducing SEM with PLS to Informetrics and Scientometrics also contributes to the knowledge base of these fields. Pragmatically, the research findings will enhance the judgment of researchers and practitioners such as editors, publishers, librarians and other information specialists in assessing journal performance. Finally, the worldwide survey findings on peer assessment of journal outlets in clinical neurology will be useful for researchers, academics or clinicians in this field.

Full textAbstract:
This dissertation examined how previous information literacy training, law student gender, age, and previously obtained education affects first, second, and third year law students selection of information sources, their understanding of common knowledge, and their decision of whether or not to give attribution to these sources. To examine these factors, this study implemented a paradigm called the principle of least effort that contended humans in general tended to complete the least amount of work possible to complete presented tasks. This study sought to discover whether law students follow this same path of completing the least amount of work possible to finish presented tasks, and whether this behavior affects information source selection, citation, and understanding of common knowledge. I performed six focus groups and crafted and disseminated an online survey to examine these factors. Via this data collection, it was discovered that law students do exhibit some differences in understanding of citation and citation behavior based on age and their year in law school. They also exhibited some differences regarding common knowledge based on their year in law school, where they received their information literacy training, and where they attend law school. Yet, no statistically significant differences were discovered regarding where one attends law school and citation and source selection. Further this study revealed law students do follow this paradigm and seek the path of least resistance to accomplish law school assignments.

Computational infrastructure for reprenting persons and citations has been available in R for several years, but has been restructured through enhanced classes "person" and "bibentry" in recent versions of R. The new features include support for the specification of the roles of package authors (e.g.,maintainer, author, contributor, translator, etc.) and more flexible formatting/printing tools among various other improvements. Here, we introduce the new classes and their methods and indicate how this functionality is employed in themanagement of R packages. Specifically, we show how the authors of R packages can be specified along with their roles in package 'DESCRIPTION' and/or 'CITATION' files and the citations produced from it.

Full textAbstract:
The professional profile of researchers is established through communication of scientific work practices, leading to the establishment of a scholarly identity. Understanding scholarly identities is currently addressed through a conceptualisation of research narrative mechanisms. Citation and citing practices are a central component of scientific communication work practices. Therefore understanding these formal communication practices of researchers through their citing behaviours may contribute to the building of scholarly identity. This study is undertaken to understand whether scholarly identity could be informed through the use of citation identities. Studies on the citation identities of individuals were conducted, using authors working in the area of Consciousness, which provided a diverse field of participants for the testing of citation analysis techniques. This is accomplished through methodological development and further examined using a combination of field-level and individual-level analyses. A new methodology was developed for the generation of citing identities, based on the calculation of the Gini coefficient and the citee-citation ratio of authors' citing profiles. The resu!ting relationship was found to have high levels of consistency across a heterogenous set of researchers. An exploration of identification of author characteristics was subsequently undertaken using the new methodology and existing citation analysis techniques. The techniques were successful in identifying departures from conventional citation practice, highlighting idiosyncrasies well, but otherwise understanding of scholarly identity through citation analysis was only marginally successful. Aportion of the difficulty of achieving clarity was the complexity of the Consciousness author set, which was useful for establishing broad applicability of a new methodology, but poor for judging its successful application. In summary, definition of citing identity type offers possibilities for improving the understanding of scholarly identity, but will require further methodology development to reach its full potential.

Full textAbstract:
Ist die Zitationsanalyse ein geeignetes Instrument zur Forschungsevaluation? Diese Dissertation untersucht, ob die zugrunde liegenden Zitationsdaten ausreichend fehlerfrei sind, um aussagekräftige Ergebnisse der Analysen zu erzielen, beziehungsweise sollte dies nicht der Fall sein, ob der Prozess, der die zitierenden und zitierten Artikel einander zurordnet, ausreichend robust gegenüber Ungenauigkeiten in den Daten ist. Ungenauigkeiten wurden als Unterschiede in den Datenwerten der bibliographischen Angaben definiert. Die untersuchten Daten setzen sich aus gezielt ausgewählten Publikationen des Web of Science (WoS) zusammen, welche eine geschichtete Stichprobe ergeben. Die bibliographischen Daten von 3.929 Referenzen wurden in einer qualitativen Inhaltsanalyse bewertet und die bibliographischen Ungenauigkeiten in einer Taxonomie zusammengefasst. Um genau festzulegen, welche von diesen tatsächlich den Zuordnungsprozess von Zitationen beeinflussen, wurde eine spezifische Untergruppe von Zitationen, d.h. Zitationen die von WoS nicht erfolgreich dem jeweilig zitierten Artikel zugeordnet wurden, untersucht. Die Ergebnisse wurden mit den Daten zweier weiterer bibliographischen Datenbanken, Scopus und Google Scholar, sowie den Daten dreier angewandter bibliometrischer Forschungsgruppen, CWTS, iFQ und Science-Metrix, trianguliert. Die Zuordnungsalgorithmen von CWTS und iFQ konnten rund zwei Drittel dieser Zitierungen erfolgreich zuordnen. Scopus und Google Scholar konnten ebenso über 60% der fehlenden Zitierungen erfolgreich mit dem entsprechenden zitierten Artikel verbinden, während Science-Metrix nur eine geringe Anzahl an Referenzen (5%) schaffte. Vollkommen falsche erste Seitenzahlen sowie Zahlendreher in Publikationsjahren können in allen Datenquellen nicht richtig zugeordnete Zitierungen verursachen. Basierend auf den Ergebnissen wurden Lösungsvorschläge formuliert, die im Stande sind den Zuordnungsprozess von Zitationen in bibliometrischen Datenquellen zu verbessern.Is citation analysis an adequate tool for research evaluation? This doctoral research investigates whether the underlying citation data is sufficiently accurate to provide meaningful results of the analyses and if not, whether the citation matching process can rectify inaccurate citation data. Inaccuracies are defined as discrepancies in the data values of bibliographic references, since they are the essential part in the citation matching process. A stratified, purposeful data sample was selected to examine typical cases of publications in Web of Science (WoS). The bibliographic data of 3,929 references was assessed in a qualitative content analysis to identify prevailing inaccuracies in bibliographic references that can interfere with the citation matching process. The inaccuracies were categorized into a taxonomy. Their frequency was studied to determine any strata-specific patterns. To pinpoint the types of inaccuracies that influence the citation matching process, a specific subset of citations, i.e. citations not successfully matched by WoS, was investigated. The results were triangulated with five other data sources: with data from two bibliographic databases in their role as citation indexes (Scopus and Google Scholar) and with data from three applied bibliometric research groups (CWTS, iFQ and Science-Metrix). The matching algorithms of CWTS and iFQ were able to match around two thirds of these citations correctly. Scopus and Google Scholar also handled more than 60% successfully in their matching. Science-Metrix only matched a small number of references (5%). Completely incorrect starting page numbers and transposed publication years can cause a citation to be missed in all data sources. However, more often it is a combination of more than one kind of inaccuracy in more than one field that leads to a non-match. Based on these results, proposals are formulated that could improve the citation matching processes of the different data sources.

Full textAbstract:
Altmetrics is a movement that aims to capture new and previously invisible types of impact of scholarly publications on social web platforms such as news sites, Wikipedia, blogs, microblogs, social bookmarking tools and online reference managers. This thesis aimtries to explore the suitability and reliability of two altmetrics resources: Mendeley, a social reference manager website, and Wikipedia, a free online encyclopedia, written collaboratively by the people who use it. At present, Wikipedia is the largest online encyclopedia.
The main objectives of this thesis are to explore the use of reference management software and Wikipedia to estimate the readership of academic literature and to compare the evolution in the coverage of LIS literature by altmetric sources and by citation indexes.
To reach these objectives, three different studies were designed. The general method to achive toobtain the initial data set was to search is that we used the Social Sciences Citation Index to retrieve articles and reviews published and indexed in the category “Information Science & Library Science”. Each record was then searched in Mendeley to obtain the number of bookmarks of the paper and the academic status of the users. Additonally, we performed a fifteen-month longitudinal study of the evolution of bookmarks in Mendeley. Afterwards, we searched for each of these articles in Wikipedia, and retrieved all the entries in which they were cited.
The Results results of these studies show that the correlation between bookmarks and citations was moderate and the overlap between the most frequently bookmarked and the most frequently cited papers increased over time. A significant share of the bookmarks were made by students and professionals, although the shares of bookmarks made by different categories of users changed as time went by. Reviews were bookmarked more frequently than articles, and papers in English had more bookmarks than papers in any other language.
Also results reveal severe limitations in the use of Wikipedia citations for research evaluation. Lack of standardization and incompleteness of Wikipedia references make it difficult to retrieve them. The number of Wikipedia citations is very low, A significant number of references are cited in biographical entries about the authors of the articles, resulting in a phenomenon of accumulated advantage. Nearly one-third of the Wikipedia citations link to an open access source, although this result is probably an underestimate of open access availability, given the incompleteness of Wikipedia citations.Altmetrics es un movimiento que tiene como objetivo capturar nuevos tipos de impacto, antes invisibles, de las publicaciones académicas en las plataformas de la web social, tales como sitios de noticias, Wikiped ia, blogs, microblogs, herramientas de marcadores sociales y gestores de referencias en línea. Esta tesis pretende explorar la pertinencia y fiabilidad de dos recursos altmétricos: Mendeley, un sitio web de gestión de referencia social, y Wikipedia, una enciclopedia online gratuita escrita en colaboración por las personas que la utilizan. Actualmente, Wikipedia es la mayor enciclopedia en línea. Los principales objetivos de esta tesis son investigar el uso del software de gestión de referencia y de Wikipedia para estimar el número de lectores de literatura académica y comparar la evolución en la cobertura de la literatura de Ciencias de la Información y Biblioteconomía (Library and Information Science, por sus siglas en inglés), según fuentes altmétricas y por índices de citas. Para alcanzar estos objetivos, se diseñaron tres estudios diferentes. El método general para acceder al conjunto de datos consistía en utilizar el Social Sciences Citation Index para recuperar revisiones y artículos publicados e indexados en la categoría «Information Science & Library Science». Se buscó cada registro en Mendeley para obtener el número de marcadores del documento y el estatus académico de los usuarios. De manera adicional, realizamos un estudio longitudinal durante quince meses para estudiar la evoluci ón en el número de marcadores. Posteriormente, buscamos cada uno de estos artículos en Wikipedia y recuperamos todas las entradas en las que fueron citados. Los resultados de estos estudios muestran que la correlación entre los marcadores y las citas era moderada y la coincidencia entre los documentos guardados en marcadores con más frecuencia y los más citados aumentó con el tiempo. Una parte significativa de los marcadores los habían hecho estudiantes y profesionales, aunque el número de marcadores hechos por diferentes categorías de usuarios cambiaron con el paso del tiempo. Las revisiones se guardaban en marcadores con más frecuencia que los artículos, y los documentos en inglés tenían más marcadores que los documentos en cualquier otro idioma. Los resultados también revelan severas limitaciones en el uso de citas de Wikipedia para la evaluación de investigación. La falta de estandarización y el carácter incompleto de las referencias de Wikipedia dificultan su recuperación. El número de citas de Wikipedia es muy bajo, y un número significativo de referencias se citan en las entradas biográficas dedicadas a los autores de los artículos, lo que supone una ventaja acumulada. Cerca de un tercio de las citas de Wikipedia se vinculan a una fuente de acceso abierto, aunque probablemente este resultado sea una subestimación de la disponibilidad de acceso a estas fuentes, dado que las citas de Wikipedia están incompletas.

Previous issue date: 2010-02-23The Competitive Intelligence (CI) is a systematic and ethical process of collection, storage and information analysis so that Organizations can obtain the competitive advantage in their businesses. For the application of this process, the CI is represented in a cycle which contains the phases of identification of necessities; planning; collections; analysis; dissipation and evaluation. The information volume to be collected and analyzed, the urgency to obtain results and the complexity of the studies of the CI, all point to the importance of the use of computer tools that support this activity. This research proposes a methodology to identify a tool that would facilitate the activities of the CI collectors and analysts, especially in the information extraction of texts needed in the transition between the phases of collection and analyses. The exploratory descriptive research was the methodology used in this work, divided into two parts: the theoretical methodology and the experimental. The first was applied to identify potential collaborating tools for the complete CI cycle and to extract information between the phases of collection and analysis. The second, to select and validate a tool (software). The tool selected was the software Zotero, which acts as an administration of bibliographica and citations reference. To validate this tool, an experiment was elaborated which contained two simulations involving the collection and extraction of information with and without the use of such tool. Two CI teams particpated in the simulations: one from Manaus and the other from São Carlos, with a total of 6 collects and 1 analyst. As a result, it was possible to identify that the software Zotero supports collectors and analysts in realizing the activities in the phases of collection and analysis.
A Inteligência Competitiva (IC) é um processo sistemático e ético de coletar, armazenar e analisar informações para que as Organizações obtenham vantagem competitiva em seus negócios. Para a aplicação deste processo, a IC é representada por um ciclo contendo as fases de identificação das necessidades, planejamento, coleta, análise, disseminação e avaliação. O volume de informações a serem coletadas e analisadas, a urgência para obtenção dos resultados e a complexidade dos estudos de IC apontam para a importância do uso de ferramentas computacionais de apoio à atividade. Esta pesquisa propõe uma metodologia para identificar uma ferramenta que facilitasse as atividades de coletores e analistas de IC, especificamente na extração de informações de textos necessária na transição entre as fases de coleta e análise. A pesquisa exploratória descritiva foi a metodologia utilizada neste trabalho, dividida em duas partes: a metodologia teórica e a experimental. A primeira foi empregada para identificar potenciais ferramentas colaborativas para o ciclo completo de IC e para a extração de informação entre as fases da coleta e da análise. A segunda para selecionar e validar uma ferramenta (software). A ferramenta selecionada foi o software Zotero, que atua como gestor de referências bibliográficas e citações. Para validar a ferramenta foi elaborado um experimento contendo duas simulações envolvendo a coleta e extração de informação com e sem o uso da ferramenta. Participaram das simulações duas equipes de IC, uma de Manaus e outra de São Carlos, num total de 6 coletores e 1 analista. Como resultado foi possível identificar que o software Zotero apóia coletores e analistas nas atividades que realizaram nas fases da coleta e da análise.

Introdução: Muito se tem discutido sobre o desafio de aumentar o impacto das publicações brasileiras. Comparado com outros países, o Brasil possui alta taxa de publicação, mas com baixo índice de citação por documento. Enquanto instituições de fomento e de pesquisa propõem a cooperação internacional como meio de aumentar o impacto das publicações científicas, os editores de periódicos contestam essa exigência. Objetivo: Avaliar se nos periódicos brasileiros de medicina, o número de citações recebidas é influenciado pelo tipo de afiliação dos autores e por outras variáveis relacionadas ao documento ou ao periódico. Métodos: Foram analisados 61 periódicos de medicina publicados no Brasil em 2012, utilizando o SCImago e o Scopus para a extração dos artigos e seus dados. O número de citações de um documento num período de cinco anos foi analisado de acordo com a afiliação dos autores (nacional, internacional ou colaboração), idioma e tipo do documento, indicador SCImago e categoria do assunto do periódico. Resultados: Análises univariadas mostraram que todas as variáveis testadas influenciaram o número de citações recebidas. Após ajuste de covariáveis pela análise multivariada observamos aumento de citações em 0,17 (IC 95%: 0,094-0,246) para documentos com afiliação em colaboração quando comparado à afiliação nacional. Aumento significativo no número de citações foram observados em documentos em idioma bilíngue (Inglês e Português) 0,329 (IC 95%: 0,256-0,402) e apenas em Inglês 0,158 (IC 95%: 0,086-0,231) quando comparado a documentos em português, do tipo artigo 1,716 (IC 95%: 1,410-2,021) e artigo de Revisão 2,931 (IC 95%: 2,618-3,245) quando comparados a artigo no prelo e que possuem categoria de assunto Hematologia 1,280 (IC 95%: 1,019-1,540), entre outros, quando comparado ao assunto geriatria e gerontologia. Conclusão: Documentos com autoria em colaboração, aumentaram, de modo discreto, o índice de citação nos periódicos de interesse, quando comparados aos de autoria nacional. Idioma, tipo do documento, indicador Scimago (cites per doc - 2 years) e categoria do assunto do periódico influenciaram significantemente o número de citações recebidasIntroduction: The challenge of increasing the impact of Brazilian science has been much discussed. Compared with other countries, Brazil has a high publication rate, but with low citation index per document. While sponsoring and research institutions are proposing international cooperation as a means of increasing the impact of science, journal editors question this demand. Objective: To evaluate whether, in Brazilian medical journals, the number of received citations is influenced by the type of authors affiliation and other variables related to the document or to the journal. Methods: A total of 61 medical journals published in Brazil in 2012 were analyzed, SCImago and Scopus were used to extract the articles and their data. The number of citations of a document over five years was analyzed according to the authors\' affiliation (national, international or in collaboration), language and document type, SCImago index and journal subject category. Results: Univariate analyses showed that all tested variables influenced the number of received citations. After adjusting for covariates by multivariate analysis, we observed an increase of citations in 0.17 (95% CI: 0.094-0.246) for documents with affiliation in collaboration when compared to national affiliation. A significant increase in the number of citations was observed in bilingual documents (English and Portuguese) 0.329 (95% CI: 0.256-0.402) and only English 0.158 (95% CI: 0.086-0.231) when compared to documents in Portuguese, document type: Article 1.716 (95% CI: 1.410-2.021) and Review 2.931 (95% CI: 2.618-3.245) when compared to Article-in-Press and that have subject category Hematology 1.280 (95% CI: 1.019-1.540), among others, when compared to geriatrics and gerontology. Conclusion: Documents with authorship in collaboration increased, in a discreet way, the citation index in journals of interest, when compared to those with national authorship. Language, document type, SCImago index (cites per doc 2 years) and journal subject category significantly influenced the number of received citations

Patent citations are extensively used for measuring the importance of patents, regarded as the knowledge flow among countries and technology fields for analysis, and applied to mapping technological trajectories for studying the evolution of the technology. However, patent citation analysis is subject to some uncertainties. Many patents are cited only with slightly relevant because they are only related to one very specific technical aspect. Moreover, many patents which should have been cited are missed. This paper aims to identify the relevant citations and the relevant un-cited patents in order to present the more precise view in the citation relationships. Both of BC and CC methods are utilized to identify the relevant citations and the relevant un-cited patents. Besides, the occurrence of relevant citations and relevant un-cited patents are related to the citation time lag (CTL), which is the time necessary for the cited patent being cited by the citing patent. The results show that citations with shorter CTL are more possible to be relevant, and this phenomenon is more obvious by BC. It reveals that it takes time for any two patents to establish their CC relations. Some relevant information cannot be dug out by CC, and therefore BC is the better approach of the identification.

In the citation analysis fields, "bibliographic coupling" appears prior to "co-citation". While co-citation have been used widely, whereas bibliographic coupling is discussed and used rarely. However, we saw more researches have been devoted to study the differences between the two citation methods recently. It has been purported that the bibliographic coupling may supplement the co-citation in some aspects. In contrast with most of the previous researches that focus on the co-citation analysis, this research compares the intellectual structures and domain contents derived from the bibliographic coupling and co-citation analysis. This study obtains dataset collected from the Scientific Literature Digital Library – Citeseer. We use the same dataset in the analysis utilizing both bibliographic coupling and co-citation, and compare the intellectual structures derived from these two analyses in terms of five indicators. We then illustrate the differences between the two outcomes and further analyze the content and interpret the result. In summary, we find the analysis using the co-citation is better than that of bibliographic coupling in two aspects – "Size of specialties" and "Nature of specialties". In the "Individual document's memberships" indicator, bibliographic coupling is suitable to researchers who want to understand the recent developments and emerging issues in the field but co-citation is more appropriate when researchers want to have an overview of the evolution history of the field. Lastly, they are equally good in the aspects of "Overlap between specialties" and "Overall structure" because both display clearly the association between various issues and the present situation of the knowledge domain.

Research fronts are the most pioneering studies of specialities. With the command of the development of research fronts, one can easily realize the focus of study in present specialities and the future development trends. In the point of planning blueprint on national development and making policies on science and technology development, research fronts are also an important reference. Consequently, it nowadays receives a great many attention and emphasis. This study is targeted at 210 highly-cited articles on OLED field, combining both bibliographic coupling and co-citation methods, exploring research fronts produced by the following three citation windows which include fixed citation window, sliding window and half life（including citing half life and cited half life）. It is undertaken to explore the advance of OLED research fronts from 2000 to 2009 and aims to analyze the values of currency index and the values of stability index and so as to decide from which values can be taken as important bases to predict the emergence of research fronts. The results show that among the above mentioned three citation windows, sliding window can find out the most many research fronts; fixed citation window is the easiest and the most effective way to find out research fronts; and half life can be a complement way for sliding window and fixed citation window to find out research fronts. In addition, research fronts has five different types, including emerging fronts, growing fronts, stable fronts, shrinking fronts, and existing fronts. Among which, emerging fronts is the symbol of future research trend and highly emphasized by scholars and experts. Furthermore, sliding window can discover the most many emerging fronts. By using bibliographic coupling and co-citation methods to make comparison in the research fronts produced by the above mentioned three citation windows, it illustrates that the effect is quite equal and can be supplement for one another. In order to find out research fronts effectively among the three citation windows, it is suggested to adopt bibliographic coupling for fixed citation window, bibliographic coupling for sliding window, and citing half life for half life. Moreover, on purpose of seeking out research fronts in a precise and systematical way, the study demonstrates the capability to predict the emergence of research fronts in the next citation window with the indexes of currency and stability. The results show that currency index 0.500 and stability index 0.400 can be the best indicator to forecast the emergence of research fronts. Based on the above research results, it is recommended that adopting fixed citation window is the easiest and the most effective way to find out research fronts; adopting sliding window can find out the most many research fronts and also discover emerging fronts at most. Last but not least, between two methods, it is suggested to adopt bibliographic coupling to find out the most many research fronts and discover the emergence of research fronts earlier. Finally, this study advises to add currency index and stability index to relative studies in order to predict the emergence of research fronts effectively and have a better command of the latest development trends of specialities.

Full textAbstract:
M.PhilCiting is the process by which scholars give recognition to research used by another academic researcher. Citation resources are tools used by academic scholars for keeping track of who did what research and the impact of the research within the discipline. Citation analysis is therefore an attempt to measure the impact and contribution of a study to the body of knowledge and research. Citation tracking and citation analysis is facilitated by making use of information resources which specialize in citations and tools for conducting citation analysis. The citation resource by The Institute for Scientific Information (ISI), Web of Science (WOS), was traditionally the citation tool of choice of academics for more than 40 years. The arrival in 2004 of Scopus, a fee-based citation resource, and Google Scholar (GS), a citation resource available for free and accessible via the Web, presented WOS with competition. The prolific growth of the citation resources created new opportunities for academics in citation tracking and citation analysis. The question of which citation resource to use in the process of tracking citations and conducting citation analysis posed a challenge to librarians and information professionals at academic institutions. It became essential to establish which citation resource was not only most relevant to use for which subject discipline, but which was the most cost-effective with the advent of shrinking library budgets. Therefore the need arose for citation resources to be compared with the aim of establishing whether the newcomers Scopus and GS are substitutes for or complementary to the traditional WOS. The objectives of this study included comparing WOS, Scopus and GS in order to determine whether evaluation criteria existed for citation resources, to define scholarly environmental sciences journals within a South African context, to determine which citation resource presented the most comprehensive citation coverage of the South African scholarly environmental sciences journals, to determine whether GS could be considered a substitute for the fee-based citation resources WOS and Scopus, and to determine how the content of the exported data for the journal sample population compared in terms of content completeness and quality. The research study consisted of a detailed literature review, followed by an empirical component using a comparative research design and the technique of purposive non-probability sampling in order to define the sample population for the study. The South African scholarly environmental sciences journals internationally accredited during the period 2004-2008 were chosen as the sample target population. The study consisted of a pilot study and three measuring instruments that were compiled based on the literature review. The results of the macro-level evaluation established that Scopus surpasses both WOS and GS. On the other hand, the micro-level evaluation concluded that WOS surpasses Scopus and GS. The content verification process conducted determined that Scopus and WOS both surpass GS. These findings were presented at the 12th Annual World Wide Web Applications conference in September 2010. The study was able to establish that GS is not a substitute for WOS and/or Scopus for the South African scholarly environmental sciences journals. In addition, it was concluded that GS can be used as a supplementary citation resource to the fee-based citation resources WOS and Scopus. It was further determined that the citation resource Scopus can be considered a substitute for WOS, which was traditionally the citation resource of choice of academic researchers.

This study applies bibliographic coupling and co-citation to investigating e-government research articles published from 1990 to 2017. The research articles, totally 3,381, indexed in Web of Science (WoS), Scopus, and union of WoS and Scopus are analyzed and compared. The results show that the important research topics of the e-government studies: 1) literature review or case studies for e-government, 2) e-government and social media, 3) open government, 4) users adopting e-government systems or services, 5) governments adopting information technology, 6) assessment of e-government in India, 7) e-government services and stakeholders. The first 5 topics demonstrate their future of research trends. However, the sixth topic, “assessment of e-government in India”, is a local research topic and is difficult to become a global research topic. The seventh topic, “e-government services and stakeholders”, is not hot after the year of 2012. The highly cited articles extracted from WoS, Scopus, and Google Scholar are not different significantly. This shows that the highly cited articles are reliable in the e-government research field. In addition, the research topics of highly cited articles are compatible to those retrieved from the results of bibliographic coupling and co-citation. However, the publishing dates of highly cited articles are not consistent to the peak periods of research topics.

Full textAbstract:
近些年來，一些論文數據庫(特別是Libra) 變得公開化并已經開始提供給用戶他們請求獲得的信息。這使得我們可以將學術社區當做一個社會網絡來進行研究，不僅分析對作者的著作進行一些統計學的分析，還研究一個作者選擇性與其他作者合著的關係，以及一個作者對其他作者的影響。我們的研究即是定義一些基於社會網絡的方法來測試前面所說的影響關係及合著關係等。我們設計的算法中，最主要的是作者影響力排名算法(AIR) 。該算法類似于著名的網頁排名算法(PageRank) ，並且把我們提取的三種關係都考慮在內。而其他的算法，都是基於某種關係或是某些關係的組合。這些算法包括:聯繫( Connection，利用合著關係、)， 追隨者數量(Follower Count ，利用發表關係)，追隨者(Follower ，利用引用關係)和平均引用數量(Balanced Citation Count ，利用合著關係和引用關係)。
這對這些算法，我們設計并研究了一些簡單的特例，通過算法之間橫向與縱向的比較來分析這些算法的特性。在不同的情形下，同一算法的表現并不一致，這是我們引入一個新的變量以便於靈活調整的原因。通過設定不同的變量值，我們利用距離衡量工具來度量這些算法結果的變化。
更進一步，我們利用不同的數據集合作為輸入來比較不同算法的表現，并利用一種距離測量工具(Spearman Footrule Distance) 來做算法之間的兩兩比較。在算法的比較中，基於排名值，我們能推斷出關於這些算法的一些結論。而基於累積值的比較，一方面驗證了這些結論的正確性，另一方面也展現出作者影響力排名算法(AIR) 的優越性。同時， 一些來源於現實生活中的排名結果，也可以用來串串證作者影響力排名算法(AIR) 的準確度。
In recent years, some of the publications database become more publically accessible, and are starting to provide additional information users can query (this is specially the case with Libra). This allows us to study the author community as a social network, analyzing not only the statistics about papers published by an author, individually at a time, but also an author’s choice and extent in connecting to other authors (co-authoring), and an author’s influence on other authors. Our approach is todesign various social network type of metrics to measure the traits defined above.
The main algorithm Author Influence Ranking (AIR), which is analogous to PageRank algorithm, is defined by taking all three relationships into consideration. Other algorithms, based on a single relationship or combination of different relationships, include: Connection, ranking algorithm using coauthor-ship; Follower Count, ranking algorithm using the number of authors who cite papers of a particular author; Follower, ranking algorithm using citation-ship; Balanced Citation Count, ranking algorithm using citation counts normalized by coauthors.
To show properties of different algorithms and do comparison among them, we design and study primitive cases. For some algorithms, the teleportation vector leads to the deviation at certain extent. Therefore, we study different teleportation vectors by tuning a parameter β(details discussed in Chapter 4) from 0 (uniformly distributed) to 1 (proportional to authors’ productivity). With different β, we define Distance to measure the changes in results of these algorithms.
Furthermore, comparisons among these algorithms are conducted by using different publication dataset and we choose Spearman Footrule Distance in our experiment to do comparison for pair of algorithms. Rank value and cumulative value are used in the comparisons: based on the comparisons using rank value, we conclude several observations regarding these algorithms. While the comparisons based on cumulative value help us confirm the "efficiency" of AIR. For using AIR metric, we can find out those really influential researchers who may not be ranked high by other metrics. We study the influence of Turing award winners and all the Turing Award winners scored at least "B", from which we can see AIR’s "accuracy". We also apply AIR metric in the real situation. We study researchers who have Grade "A"(the grade will be discussed in Chapter 6) in Influence and find most of them have good positions in reality, which help us justify the validity of AIR.("efficiency", "accuracy" and "validity" will be discussed more in Chapter 6.)

Full textAbstract:
Described as accommodating both traditional and new information spaces (Fourie 2002: 53), the Web has significantly changed the milieu of research and study. The study determined how this changing research and study environment has affected the research behaviour of students in African higher education environments, specifically at the research entry level of master's degree programmes. The study examined both explicit examples of the affect of the Web on students' citation behaviour and tacit influences that may have determined the extent of this affect. Explicit examples of the affect of the Web were drawn from analysing changes in the citation patterns of Master of Information Studies (MIS) theses during a period of access to the Web, and specifically in the years 1996, 1999 and 2002. Tacit influences on students' citation behaviour were inferred from an investigation of the level and nature of MIS supervisors' use and support of the Web for research and of a background study of the facilities, resources and services supporting student access to the Web at the University of Natal, Pietermaritzburg. Findings of this study concluded that the use of the Web medium has grown and in 2002 accounted for 17.5% of all citations included in MIS bibliographies. However use of this medium is disparate with a few bibliographies accounting for much of this growth. Findings indicated that the Web medium was mostly utilised for the delivery of sources that do not meet the traditional description of a scholarly source. The study also found that the Web was used as an alternative medium for the delivery of informal and grey literature sources without necessarily increasing the level of use of these sources. The study revealed greater support for this medium from the masters programme's supervisors than was evidenced from a citation analysis of the bibliographies of theses. Disparities in the support of this medium for research, within the University of Natal, Pietermaritzburg's supporting infrastructure was also observed. Recommendations drawn from these conclusions include the need for greater intervention from teaching faculty, librarians and the institution in the provision of clear guidelines of expectations, relevant instruction and sufficient physical access at points of expertise, to effectively support the use of Web resources.Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

This study used bibliometric methods including direct citation, bibliographic coupling and coauthorship to analyze interdisciplinary characteristics in Library and Information Science (LIS) and used Brillouin’s Index , an interdisciplinary indicator, to measure the interdisciplinary degree. In addition, the interdisciplinary characteristics in library science, information science, types of references and 10 LIS journals are compared, and interdisciplinary changes over time are tracked. Subjects were 27,678 references of 1,536 articles, 8,906 references from 1,536 citing articles which share items in their reference lists and 1,536 authors of 644 co-authored articles published in 10 LIS journals, consisting of 5 library science journals and 5 information science journals, systematic sampling 15%. The major findings were summarized as follows. LIS literature and authors has the heaviest reliance on LIS literature and authors, following general science literature and authors. Library science has interdisciplinary characteristics distinct from information science. For example, library science is a social science-oriented discipline while information science is a natural science-oriented discipline. As for the percentage distribution of discipline, large differences in percentage distribution between the two highest ranking disciplines are obvious, and about 80％ of citations or coauthors concentrate top 5 disciplines ranked by percentage distribution of discipline. In addition, the ranking of some disciplines in humanities, social sciences and natural sciences has been raising every 10 years. Degree of interdisciplinarity in information science is higher than library science. However, degree of interdisciplinarity in information science journals is not higher than all library science journals. Among 10 LIS journals, Library Resources & Techninical Services has the lowest degree of interdisciplinrarity, while Scientometrics has the highest degree of interdisciplinarity. In addition, a reverse relationships between the percentage distribution of citations to LIS literature and the degree of interdisciplinarity. The higher percentage distribution of citations to LIS literature or coauthor in LIS , the lower the degree of interdisciplinarity. Degree of interdisciplinarity in LIS and information science has positive growth trends, but not all the analysis results by three bibliometric methods have shown library science also has the same trends. The number of discipline has positive growth trends in LIS, library science and information science. Further, 30 disciplines ranking in LIS, library science and information science analyzed by three bibliometric methods are obviously consistent. Especially, direct citation and bibliographic coupling has the highest consistency among three bibliometric methods. In the view of the high consistency, three bibliometrics methods can replace one another. However, the possible reason that explains different results analyzed by three bibliometric methods is the difference between bibliometric theories. It is not surprised to see the different analysis results from different samples. Comparing a reference to a co-author, it is more difficult to increase a co-author than a reference does. When applying for the three bibliometric methods, it is important to make sure the meaning of interdisciplinarity, then take proper bibiometric method. For example, co-authorship can present more practical interdisciplinary interaction, direct citation can track the information flow among literature, and bibliographic coupling can show interdisciplinary characteristics existing in core references. In short, both library science and information science has their disciplinary nature, library science and information science should be analyzed separately to present individual interdisciplinary characteristics. Also, books and journal articles are main cited sources, book citations should be included in citations samples.

This study uses bibliometric methods including keywords analysis, bibliographic coupling and co-citation to analyze subject distribution and change in library and information science (LIS) over the last 15 years (from 1995 to 2009). To study changes, the analyses were time-sliced into three 5-year periods. The research targets are library and information science(LIS) journal articles from the Social Science Citation Index (SSCI) database. A total of 363 highly-cited articles are selected. The part of keywords analysis utilizes the descriptors of LISA database to quantitatively analyze the subject of journal articles. The results of this study show a stable structure of two distinct research areas: “Information Seeking and Retrieval (ISR)” and “Bibliometrics”. However, through three 5-year periods, the proportion of “ISR” is decreasing. On the other side, the proportion of “Bibliometrics” is increasing gradually. During the third period (2005-2009) in particular, the proportion of “Bibliometrics” is over 80% from three methods. The popular subjects related to “Bibliometrics” are “H-index”, “Scientific visualization”, “Interdisciplinary study”, “Citation analysis”, “the science structural of a nation” and so on. Although “Internet applications “ didn’t replace the LIS original paradigm, due to the rapid development of internet, “ISR” and “Bibliometrics” show signs of coming closer together.
