I have done a comparative gender study of Library of Congress Classification from 1900 and 2001. I have also used a hermeneutic method and ideological critics to find out what picture of women the both systems shows. In my comparative study of the both systems I have found low update of classes which relates to women in the new classification system. Men seem to be a norm in the system, because men are not defined in classes related to both men and women. But many classes related to women are named Women as and Women in The study also shows that women are more related to subjects about family and marriage than men are. In classes for work and studies women are defined as another society group than the norm, the man. The old system from 1900 follows the historical context from the time of 1900. The new system follows a gender hierarchy where the man has the dominated role, according to Yvonne Hirdmans theory about the gender system.Uppsatsnivå: D

Full textAbstract:
The UDC is attractive to different stakeholders across the information sector because of its wide-spread application, large vocabulary and availability in an electronic format. Modern information retrieval systems have the need but also the capacity to support flexible and interactive retrieval systems. The role of classification in such systems is to serve as an underlying knowledge structure that provides systematic subject organisation and thus complements the search using natural language terms. There are, however, specific requirements that must be satisfied in order to make efficient use of classification and these are not well known outside the library domain and are poorly implemented in library systems. This is especially the case for synthetic classifications, such as UDC, because its elements are meant to be manipulated by the system to fulfill different functions (a flexible systematic display, browsing or search purposes). This report summarizes the most important functionalities of the UDC that need to be taken into account during the implementation process. Important issues about the relation between the UDC schedules in electronic form - UDC Master Reference File and a classification tool (an authority file) that may be built on it, are highlighted. A better understanding of the UDC system's functionality may improve or facilitate its implementation and lower the costs of system maintenance which may be relevant for both prospective users and legacy
systems.

Full textAbstract:
Library inventories are widely acknowledged for their importance in intellectual history, but there are few detailed studies of library classification in this context. The discussion centres on the inventories of 36 English private libraries from 1521 to 1640, with a view to understanding what could have prompted a compiler to adopt one system of arrangement instead of another. Nine of the inventories are transcribed from unpublished manuscripts, including lists of the books of William Paget, 4th Baron Paget (1617), William Somner (1639), and a previously unidentified catalogue of the books of the physician William Rant (1595). The classification of books was a matter of some concern at the time: the problems raised by library classification were beginning to attract the attention of writers on the subject, and a compiler's approach was not always as haphazard as it may seem at first. On the whole, however, the classification of books was more spontaneous than deliberate, and it is for this reason that it was often finely attuned to the professional concerns and personal interests of owners, as well as to the cultural climate of the time (religious controversies, interest in languages other than Latin). The medieval trivium was losing its momentum in the classifications of the period, and mathematics, for centuries associated with the quadrivium in classifications, was viewed in a new light under the influence of Neo-Platonism. New trends in library classification appeared side by side with age-long practices, thereby underscoring the deeply transitional nature of the period.

Full textAbstract:
The paper addresses issues in establishing a user-friendly systematic collection arrangement following a merger of two high school and college library collections classified according to UDC. In the way it was used, this scheme presented some weaknesses with respect to collection usage. Due to the disciplinary nature of UDC, subjects and phenomena are dispersed in the scheme according to the disciplines in which they are the subject of study. At the same time students in a school library often seek interdisciplinary subjects and need access to clusters of documents which according to UDC may be classed in several different knowledge areas. The author illustrates how this problem was resolved by re-arranging the collection according to phenomena. This was achieved by interpreting UDC numbers as if they represented specific phenomena. Thus, by superimposing some local indexing rules onto a disciplinary knowledge organization system it was possible to collocate interdisciplinary subjects under a single class number. Furthermore, by reversing subject numbers and form auxiliaries (atlases, dictionaries, textbooks etc.) which is an option envisaged in the design of UDC, documents were collocated in the way they are most frequently used by students. The author suggests that, in practice, one often needs to overcome the constraints of disciplinary classification and he discusses the approach used in his school library collection.

Full textAbstract:
There are four normed division algebras over real numbers, namely real numbers, complex numbers, quaternions, and octonions. Lack of commutativity and associativity make it difficult to investigate algebraic and geometric properties of octonions. Eigenvalue problem of octonionic Hermitian matrices is one of the interesting studies where we can see this difficulty of extending the basic properties from complex Hermitian matrices to octonionic Hermitian matrices. This includes the notion of orthogonality and decomposition of a Hermitian matrix using its eigenvalues and eigenvectors.Liping Huang and Wasin So derived explicit formulas for computing the roots of quaternionic quadratic equations. We extend their work to octonionic case and solve octonionic left quadratic equations. We represent left spectrum of two by two octonionic Hermitian matrix using the solutions to corresponding octonionic left quadratic equation and identify the family of matrices which admit non-real left eigenvalues. For three by three case we review previous work by Tevian Dray and Corinne Manogue of real eigenvalue problem and study characteristic equations which admit non-real roots that are correspond to non-real left eigenvalues. Finally, we discuss the right spectrum using the associator method, and provide examples using "pyoctonion" python library. Interesting applications and open problems for future studies in this literature are also included.

This thesis examines automated genre classification in literature. The approach described uses text based comparison of book summaries to examine if word similarity is a feasible method for identifying genre types. Genres help users form impressions of what form a text will take. Knowing the genre of a literary work provides librarians, information scientists, and other users of a text collection with a summative guide to its form, its possible content, and what its members are about without having to peruse individual topic titles. This makes automatically generating genre labels a potentially useful tool in sorting unmarked text collections or searching the web. This thesis provides a brief overview of the problems faced by researchers wishing to automate genre classification as well as the current work in the field. My own methodology will also be discussed. I implemented two basic methods for labeling genre. The results collected using them will be covered, as well as future work and improvements to the project that I wish to implement.

Olsen, Brian Mark. "A Design Framework that Employs a Classification Scheme and Library for Compliant Mechanism Design." BYU ScholarsArchive, 2010. https://scholarsarchive.byu.edu/etd/2298.
Full textAbstract:
Limited resources are currently available to assist engineers in implementing compliant members into mechanical designs. As a result, engineers often have little to no direction incorporating compliant mechanisms. This thesis develops a conceptual design framework and process that utilizes a proposed classification scheme and a library of mechanisms to help engineers incorporate compliant mechanisms into their applications. As the knowledge related to the synthesis and analysis of compliant mechanisms continues to grow and mature, and through the classification scheme established in this thesis, compliant mechanisms may become more extensively used in commercial mechanical designs. This thesis also demonstrates a design approach engineers can use to convert an existing rigid-body mechanism into a compliant mechanism by using the established classification scheme and a library of compliant mechanisms. This approach proposes two possible techniques that use rigid-body replacement synthesis in conjunction with a compliant mechanism classification scheme. One technique replaces rigid-body elements with a respective compliant element. The other technique replaces a complex rigid-body mechanism by decomposing the mechanism into simpler functions and then replacing a respective rigid-body mechanism with a compliant mechanism that has a similar functionality. These techniques are then demonstrated by developing and designing a competitive and feasible compliant road bicycle brake system.

Full textAbstract:
The Universal Decimal Classification (UDC) is currently used in the National Library of Liechtenstein (NLL). Librarians have been using the 1978 German medium edition â Dezimalklassifikation: Internationale Mittlere Ausgabe: FID 550â published by the German Institute for Standardization (Deutsches Institut für Normung - DIN). Since DIN ceased its activity as UDC publisher, there has been no other interest in publishing a German edition of the classification. Hence, the NLL library lacks a suitable and up-to-date UDC edition in German to extend and modernize its content indexing. In order to update information access to its collection, the NLL is faced with two options: reclassifying books to the more recent edition of the UDC or reclassifying to DDC22(Dewey Decimal Classification), recently translated and published in German. In 2007-2008, as part of a graduate library & information science programme internship, research was conducted to assess the suitability of the two classification schemes in supporting collection management and information access in the NLL - with relation to costs, work expenditure and practical classification issues. This text is a brief summary from the final research report.

Die Bibliotheken, die reichen Sammlungen über den Islam haben, stehen vor den Problemen der Organisation des Wissens während Klassifizierung von Materialien über den Islam. Denn die Standard-Klassifikationssysteme wie DDC-Sachgruppe, Library of Congress Klassifikation, Universal Decimal Klassifikation, Bliss Klassifikation, und Colon Klassifikation, die durch eine große Anzahl von Bibliotheken verwendet werden, nicht genügend Platz und angemessene Zählen oder Hierarchie für islamischen Wissens haben. Anschließend, verschiedene alternative Lösungen wurden von Gelehrten sortiert und von diesen Bibliotheken adoptiert. Diese Lösungen umfassen Erweiterungen im Standard-Klassifikationssysteme mit unterschiedlichen Ansätzen und indigenen Klassifikationssysteme für den Islam gemacht. Trotz dieser Lösungen, die Bibliotheken hatten Probleme und sind immer noch unzufrieden. Dieses Forschungsprojekt untersucht dieses Problem. Es hat die Literatur zu diesem Thema bewertet, und empirischer Daten gesammelt, die im Bibliotheks-und Informationswissenschaft (LIS) Bereich in neun verschiedenen Ländern der Welt relevant sind. Die Forschung verwendet Interviews (persönlich oder per Telefon) als wichtigstes Instrument für die Datenerfassung. Die Durchsicht der Literatur und die Analyse der empirischen Daten bestätigte die Existenz des Problems und die Unzufriedenheit der Bibliotheken. Folglich, die optimale Lösung dass in der Literatur und von recherchierten Bevölkerung angegeben ist, wurde vorgebracht worden in diese Forschung: Entwicklung einer unabhängigen und umfassenden Klassifikationssystem für islamischen Wissens. Dieses System wurde von den Gelehrten der LIS und Islamische Studien überprüft worden.The Libraries that have rich collections on Islam are facing the problems of knowledge organization while classifying materials on Islam. This is because the standard classification systems like Dewey Decimal Classification, Library of Congress Classification, Universal Decimal Classification, Bliss Classification, and Colon Classification, which are used by a huge number of libraries, have not provided with sufficient place and proper enumeration or hierarchy for Islamic knowledge. Subsequently, different alternative solutions have been sorted by scholars and opted by these libraries. These solutions include expansions made in standard clas-sification systems with different approaches and indigenous classification systems for Islam. Despite these solutions, the libraries had problems and were not satisfied. This study has addressed this problem, reviewing litera-ture on the problem and collecting empirical data from relevant libraries and scholars of Library and Information Science (LIS) from nine different countries of the world, using interviewing as data collection instrument. Findings of literature and empirical data confirmed the existence of prob-lem and dissatisfaction of libraries. Consequently, the optimal solution in-dicated in literature and by researched population has been brought for-ward in this research, i.e., development of an independent and comprehensive classification system for Islamic knowledge. This system has been got verified by the scholars of LIS and of Islamic Studies.

Lee, Deborah. "Modelling music : a theoretical approach to the classification of notated Western art music." Thesis, City, University of London, 2017. http://openaccess.city.ac.uk/17445/.
Full textAbstract:
The classification of notated Western art music is a perennial issue. This thesis analyses and models the knowledge organization of notated Western art music in order to elucidate a theoretical understanding of these classification issues and to offer new ways of viewing music classification in the future. This thesis also considers how music classification contributes to developments in general knowledge organization and compares the classification of Western art music across the library and information science (LIS) and music domains. The research is conducted using a number of analytical techniques, including examining music knowledge organization discourse, analysing examples of LIS classification schemes, unpicking discussions of classification in the music domain and analysing composer worklists in the music domain. After ascertaining how music classification fits into theories of faceted classification, three important facets of music are identified: medium, form and genre, and a quasi-facet of function. These three facets are explored in detail over five chapters: the binary vocal/instrumental categorisation; classifying numbers of instruments or voices, accompaniment, arrangements and “extreme” mediums; classifying musical instruments; classifying musical forms and genres; and the quasi-facet of function. Five resulting models of music classification are presented. Model 1 demonstrates the complexities of classifying musical medium, including the interlinked relationships between different parts of musical medium. Model 2 offers a solution to LIS classification’s largely binary view of vocal and instrumental categorisation by suggesting a novel new category: “vocinstrumental”. Model 3 illuminates the entrenched dependencies between facets of music, highlighting one of the structural issues with LIS classifications of music. Model 4 offers an original structure of music classification, proposing a simultaneous faceted and genre-based system. Model 5 compares classification in the music and LIS domains, offering a novel way of considering domain-based classification by codifying various types of relationships between the LIS and domain classifications. This thesis also contributes to the theory and practice of knowledge organization in general through the development of novel frameworks and methodologies to analyse classification schemes: the multiplane approach, reception-infused analysis, webs of Wirkungs (connections) between classification schemes and stress-testing.

Full textAbstract:
Arabic news articles in heterogeneous electronic collections are difficult for users to work with. Two problems are: that they are not categorized in a way that would aid browsing, and that there are no summaries or detailed metadata records that could be easier to work with than full articles. To address the first problem, schema mapping techniques were adapted to construct a simple taxonomy for Arabic news stories that is compatible with the subject codes of the International Press Telecommunications Council. So that each article would be labeled with the proper taxonomy category, automatic classification methods were researched, to identify the most appropriate. Experiments showed that the best features to use in classification resulted from a new tailored stemming approach (i.e., a new Arabic light stemmer called P-Stemmer). When coupled with binary classification using SVM, the newly developed approach proved to be superior to state-of-the-art techniques. To address the second problem, i.e., summarization, preliminary work was done with English corpora. This was in the context of a new Problem Based Learning (PBL) course wherein students produced template summaries of big text collections. The techniques used in the course were extended to work with Arabic news. Due to the lack of high quality tools for Named Entity Recognition (NER) and topic identification for Arabic, two new tools were constructed: RenA for Arabic NER, and ALDA for Arabic topic extraction tool (using the Latent Dirichlet Algorithm). Controlled experiments with each of RenA and ALDA, involving Arabic speakers and a randomly selected corpus of 1000 Qatari news articles, showed the tools produced very good results (i.e., names, organizations, locations, and topics). Then the categorization, NER, topic identification, and additional information extraction techniques were combined to produce approximately 120,000 summaries for Qatari news articles, which are searchable, along with the articles, using LucidWorks Fusion, which builds upon Solr software. Evaluation of the summaries showed high ratings based on the 1000-article test corpus. Contributions of this research with Arabic news articles thus include a new: test corpus, taxonomy, light stemmer, classification approach, NER tool, topic identification tool, and template-based summarizer – all shown through experimentation to be highly effective.Ph.

The aim of this master’s thesis is to examine how libraries can organize their collections in terms of library shelving and displays and to what extent these activities stem from a desire to create a user-friendly library. The thesis is based upon a case study of Arkenbiblioteket in Sweden and the material consists of a literature study and qualitative, semi-structured interviews with three librarians at Arkenbiblioteket. The theoretical framework consists of theories on information-seeking behavior, classification and displays. These theories form the basis of the analysis of the empirical material.The main reason for the changes in shelf arrangement at Arkenbiblioteket was a desire among the library staff to create a user-friendly library. Their experience of the previously used SAB classification system was that it was outdated and suited neither the collection nor the users’ information-seeking behavior. Many Swedish libraries have recently decided to change from SAB classification to the internationally used Dewey decimal classification. This, however, was not an option for Arkenbiblioteket as the staff believed that DDC, with its classification’s notation based on Arabic numerals, was likewise ill-suited for their users. As a result they created their own classification and shelving system using text in plain and colours for each category. Furthermore, the staff at Arkenbiblioteket focuses on library displays with commercial inspiration from bookshops. They work with face-front displaying techniques to inspire users. In conclusion, both the new shelving system and the library displays are designed to suit the users and their information-seeking behavior, whether they are conducting a specific search or merely browsing. The feedback from users on the new shelving system has been mainly positive.This study is a two years master’s thesis in Archive, Library and Museum studies.

Educational Digital Libraries (DLs) are complex information systems which are designed to support individuals' information needs and information seeking behavior. To have a broad impact on the communities in education and to serve for a long period, DLs need to structure and organize the resources in a way that facilitates the dissemination and the reuse of resources. Such a digital library should meet defined quality dimensions in the 5S (Societies, Scenarios, Spaces, Structures, Streams) framework - including completeness, consistency, efficiency, extensibility, and reliability - to ensure that a good quality DL is built.
In this research, we addressed both external and internal quality aspects of DLs. For internal qualities, we focused on completeness and consistency of the collection, catalog, and repository. We developed an application pipeline to acquire user-generated computing-related resources from YouTube and SlideShare for an educational DL. We applied machine learning techniques to transfer what we learned from the ACM Digital Library dataset. We built classifiers to catalog resources according to the ACM Computing Classification System from the two new domains that were evaluated using Amazon Mechanical Turk. For external qualities, we focused on efficiency, scalability, and reliability in DL services. We proposed cloud-based designs and applications to ensure and improve these qualities in DL services using cloud computing. The experimental results show that our proposed methods are promising for enhancing and enriching an educational digital library.

Full textAbstract:
The thesis examines the decoration of Greek bookbinding, through the study of the leather-covered bindings from the monastery of Saint Catherine in Sinai, Egypt. The manuscript collection is remarkable for the variety of binding styles that represent mainly Greek but also other bookbinding traditions, including Georgian. Syrian and Eastern European. The examination of the decorative motifs tooled on the leather covered bindings aims to identify the style and characteristics of bookbinding at the monastery. Moreover, links between and evidence for specific bindings and the manuscripts they contain are established by grouping them and relating them to specific binders and bookbinding workshops. The workshops of the monastery are examined in parallel with groups of bindings that were imported into the monastery. The extent to which the trade in books and the circulation of binding techniques between the monastery and the west was a reflection of the relations of the monastery with its dependencies is also explored. Rubbings of the approximately 5500 tool impressions on the 1195 decorated bindings have provided the core research material. They have been identified, classified and organized into a descriptive electronic database. Imaging techniques have been developed to compare the scanned impressions, which permitted the identification of impressions of the same finishing tools. Based on the identity of their decorative tools and on the process of comparison of their structural features, a number of the bindings have been ascribed to a total of 70 specific workshops, whose dates and origins are explored. 16 of these workshops - nine from the monastery of St Catherine and seven from elsewhere, which produced bindings imported to the monastery, are discussed analytically. In addition to that, 40 original bookbinding finishing tools were discovered at the monastery during this research, which have provided invaluable material for our understanding of the tooling methods and particularities of decorated book covers at the monastery. The largest corpus of finishing tools used on Greek bindings to date has been compiled to provide a reference tool which will aid future research on Greek bookbinding.

The paper describes an approach to improving classification-based subject access in a library catalogue. In order to enhance the use of UDC numbers in information retrieval, the authors have represented classification with thesaurus descriptors and implemented this solution in an automated way. In addition, descriptors in more than one language were used to interface classification. The authors present a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for bibliographic and subject authority records (i.e. the UDC-based multilingual thesaurus) with MARCXML support for data transfer. The multilingual thesaurus was built according to the existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. The authors illustrate how this approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users.

Full textAbstract:
Classification is a fundamental tool in the organisation of any library collection for effective information retrieval. Several classifications exist, yet the pioneering Dewey Decimal Classification (DDC) still constitutes the most widely used scheme and international de facto standard. Although once used for the dual purpose of physical organisation and subject retrieval in the printed library catalogue, library classification is now relegated to a singular role of shelf location. Numerous studies have highlighted the problem of subject access in library online public access catalogues (OPACs). The library OPAC has changed relatively little since its inception, designed to find what is already known, not discover and explore. This research aims to enhance OPAC subject searching by deriving facets of the DDC and populating these with a library collection for display at a View-based searching OPAC interface. A novel method is devised that enables the automatic deconstruction of complex DDC notations into their component facets. Identifying facets based upon embedded notational components reveals alternative, multidimensional subject arrangements of a library collection and resolves the problem of disciplinary scatter. The extent to which the derived facets enhance users' subject searching perceptions and activities at the OPAC interface is evaluated in a small-scale usability study. The results demonstrate the successful derivation of four fundamental facets (Reference Type, Person Type, Time and Geographic Place). Such facet derivation and deconstruction of Dewey notations is recognised as a complex process, owing to the lack of a uniform notation, notational re-use and the need for distinct facet indicators to delineate facet boundaries. The results of the preliminary usability study indicate that users are receptive to facet-based searching and that the View-based searching system performs equally as well as a current form fill-in interface and, in some cases, provides enhanced benefits. It is concluded that further exploration of facet-based searching is clearly warranted and suggestions for future research are made.

Both integrated library management systems and DAISY production and manipulation tools become widespread. We study how they could be combined to build a ready-to-use digital library with DAISY as its core format. The obtained framework should cover the entire book processing, from digital files provided either by publishers or by scanning printed material, until the delivery of DAISY content to end-users in a possibly secured way. We first give a functional description of the framework we have in mind. Then, we examine the existing tools of interest and give some tracks for further software developments.

Full textAbstract:
This is a preprint published in Journal of Documentation 62 (4): 462-481.
Purpose: This paper examines William Stetson Merrill, the compiler of A Code for Classifiers and a Newberry Library employee (1889-1930) in an attempt to glean lessons for modern information studies from an early librarianâ s career.
Methodology/Approach: Merrillâ s career at the Newberry Library and three editions of the Code are examined using historical, bibliographic, and conceptual methods. Primary and secondary sources in archives and libraries are reviewed to provide insight into Merrillâ s life at the Newberry and his attempts to develop or modify tools to solve the knowledge organization problems he faced. The concept of bricolage, developed by Levi-Strauss to explain modalities of thinking, is applied to Merrillâ s career. Excerpts from his works and reminisces are used to explain Merrill as a bricoleur and highlight the characteristics of bricolage.
Research Implications and Limitations: Findings show that Merrill worked collaboratively to collocate and integrate a variety of ideas from a diverse group of librarians such as Cutter, Pettee, Poole, Kelley, Rudolph, and Fellows. Bliss and Ranganathan were aware of the Code but the extent to which they were influenced by it remains to be explored. Although this is an anachronistic evaluation, Merrill serves as an example of the archetypal information scientist who improvises and integrates methods from bibliography, cataloging, classification, and indexing to solve problems of information retrieval and design usable information products and services for human consumption.
Originality/Value of Paper: Bricolage offers great potential to information practitioners and researchers today as we continue to try and find user-centered solutions to the problems of digital information organization and services.

Full textAbstract:
This thesis focuses on the work of policing, regulating and monitoring of New Zealand public censorship classifications. It follows the processes and agents involved in the day-to-day practices of the enforcement of the classifications given to objects by the Office of Film and Literature Classification. Responsibility for the enforcement of the classification decisions of the Office is delegated to private agents and agencies involved in supplying audiences with classified media products - cinemas, video stores, bookstores and libraries. The thesis also documents enforcement undertaken directly by public agents of the Censorship Compliance Unit. In this case enforcement is concerned with unclassified publications circulating on the Internet. The thesis argues that the networks of agents assembled for the practices of enforcement evolve as the forms of media evolve or change. The thesis focuses on the modes of interaction between agents, media and publics enacted in the different sites of the cinema, the bookstore, the video store, the library and the Internet. It documents the work of enforcement involved in the purchase of images for a fixed period of time in the fixed site of the cinema; the purchase of books from the fixed site of the bookstore; the hire of video films and video games from the fixed site of the video store; and the borrowing of books and videos from the fixed site of the public library. It contrasts the work of enforcement in these different sites with the development of new work practices involved in the interactive, fluid and seemingly intangible yet still policed site of the Internet. It documents how the responsibilities for, and the practices of, enforcement shift between public sites of enforcement to the increasingly difficult public monitoring of the private consumption of images distributed through the media of the Internet. It pays attention to how different methods and strategies of enforcement have been developed in response to both the classification and consumption of the expanding variety of mobile media and the proliferation and consumption of images in the unclassified and fluid world of the Internet.

Full textAbstract:
We describe an implementation of a multi-threaded NFFT (nonequispaced fast Fourier transform) software library and present the used parallelization approaches. Besides the NFFT kernel, the NFFT on the two-sphere and the fast summation based on NFFT are also parallelized. Thereby, the parallelization is based on OpenMP and the multi-threaded FFTW library. Furthermore, benchmarks for various cases are performed. The results show that an efficiency higher than 0.50 and up to 0.79 can still be achieved at 12 threads.

Full textAbstract:
Background: Controlled vocabularies in the molecular biology domain exist to facilitate data integration across database resources. One such tool is the Gene Ontology (GO), a classification designed to act as a universal index for gene products from any species. The Gene Ontology is used extensively in annotating gene products and analysing gene expression data, yet very little research exists from a library and information science perspective exploring the design principles, philosophy and social role of ontologies in biology. Aim: To explore how molecular biologists, in creating the Gene Ontology, devised guidelines and rules for determining which scientific concepts are included in the ontology, and the criteria for how these concepts are represented. Methods: A domain analysis approach was used to devise a mixed methodology to study the design of the Gene Ontology. Concept analysis of a GO term and a critical discourse analysis of GO developer mailing list texts were used to test whether ontological realism is a tenable basis for constructing objective ontologies. A comparison of the current GO vocabulary construction guidelines and a study of the reasons why GO terms are removed from the ontology further explored the justifications for the design of the Gene Ontology. Finally, a content analysis of published GO papers examined how authors use and cite GO data and terminology. Results: Gene Ontology terms can be presented according to different epistemologies for concepts, indicating that ontological realism is not the only way objective ontologies can be designed. Social roles and the exercise of power were found to play an important role in determining ontology content, and poor synonym control, a lack of clear warrant for deciding terminology and arbitrary decisions to delete and invent new terms undermine the objectivity and universal applicability of the Gene Ontology. Authors exhibited poor compliance with GO data citation policies, and in re-wording and misquoting GO terminology, risk exacerbating the semantic problems this controlled vocabulary was designed to solve. Conclusions: The failure of the Gene Ontology to define what is meant by a molecular function, the exercise of power by GO developers in clearing contentious concepts from the ontology, and the strict adherence to ontological realism, which marginalises social and subjective ways of classifying scientific concepts, limits the utility of the ontology as a tool to unify the molecular biology domain. These limitations to the Gene Ontology design could be overcome with the development of lighter, pluralistic, user-controlled ‘open ontologies’ for gene products that can work alongside more traditional, ‘top-down’ developed vocabularies.

Magister Bibliothecologiae - MBiblIn the field of user studies, very little research has been done on rendering of services in academic libraries. These services need to be examined in depth in order to be able to provide academic library users with more appropriate information services. There is clearly a need to determine what the real needs of academic library users are and how they prefer to look for information. The rapid growth of information technology could have a great influence on service rendering to academic library users.

Full textAbstract:
The aim of this master's thesis is to examine how shelving is organized among Swedish libraries that have switched from the Swedish classification system SAB to using the DDC, and what problems arise in this process. The method used is interviewing librarians at Swedish university and special libraries. The Swedish national library announced their swap to the DDC in 2008, and several libraries followed suit. The reported advantages with a switch were mainly that using an international classification system meant that Swedish libraries would no longer have to undertake a time consuming classification work, since most of the foreign literature already is Dewey classified. Disadvantages were that the DDC is not adapted to Swedish circumstances. Research on open shelving show that obtaining a browsable book collection requires a broad shelf classification. If libraries motivate their shelving solution by wanting browsable collections, efforts will be made to keep shelf classification broad enough. Certain categories have by tradition been shelved separately in Swedish libraries, and this study seeks to find out if a classification shift changes this custom, and if so, whether or not this is only attributable to the change of classification. Findings show that libraries motivated their swapping of classification mostly by the perceived flaws of the SAB system, and not by the promise of saving time, nor by the benefits of the DDC system. Most librarians seemed to lack sufficient knowledge of the DDC, which may be a reason why librarians claimed that the workload necessary to re-shelve the stock was the biggest drawback with switching to the DDC. Most libraries desired browsable shelves, and therefore used shelf lists to better be able to adapt the classification system to the stock. The custom of shelving certain categories separately survived the classification swap for some categories, but not for others. In the latter case this can be ascribed to a dwindling use of these specific categories by the patrons.

Full textAbstract:
This case study examines the new media presentation system in Alby public library. The aim is to explore if the contemporary Zeitgeist, wich according to the sociologist Zygmunt Bauman, could be described as liquid modernity, has affected how the system was formed. The purpose is to find out how that would affect users and staff of public libaries of the contemporary. Interviews were conducted with the library staff, and plans and documents concerning the media presentation system was examined. The empirical part of this thesis starts with a study of the process that resulted in the new presentation system while the second part examines the system as such. I discovered that both the media presentation system, and the process which preceded it, contained aspects that could be traced to liquid modernity. However, I also found lingering signs of solid modernity, wich is the term Bauman uses to denote the modern era. The media presentation system could thus be described as a combination of solid and liquid modernity. I argued that the new media arrangment is a compromise with several disadvantages for both users and the library staff. The interplay between solid and liquid modernity in the contemporary public library results in a divergent situation for users and staff. On the one hand, it gives more freedom to use the library according to their own ideas. However, old structures, such as classification systems, sets limits for this development.

To help librarians understand the impact of emerging technologies on participatory service building, this study takes social media as an example to explore how to use different engagement strategies that social media provides to engage more users. This research provides three major contributions to the library system. The libraries can use the resultant engagement strategies to engage its users. Additionally, the best-fit strategy can be inferred and designed based on users' preferences. Lastly, the users' preferences can be understood based on data analysis of social media. Three such contributions have been put together to fully address the proposed question.

Full textAbstract:
The purpose of this Master’s thesis is to study how well the online catalogue of The Music Library of Sweden works when ordinary users are searching for sheet music. The issues studied are: Why do the users fail to find the sheet music they are looking for? Do the users take advantage of the possibilities that the classification codes of the SAB system offer? If not, why?
The source material of the study is 144 comments from a user questionnaire about the online catalogue and, in addition, the search log for one day (513 queries). The comments were sorted into seven groups depending on the type of information need, for example searches for certain instrumentation or genres and problems with spelling. Each analysis ends with suggestions for improvements of the catalogue and its instructions.
The thesis show, according to the Zipf’s principle of least effort, that sheet music searching in the online catalogue is demanding too much effort and knowledge of the users. Searching with SAB classification codes is too complicated which may be the explanation why only 2 percent of the queries in the log are code searches. In 51 of the 76 cases where users failed to find sheet music the queries would have succeeded if the patrons had used classification codes. The SAB system is thus not used as often as it deserves.
The variety and amount of failed queries in the material show that sheet music is difficult to search, for several reasons, for example the complex construction of uniform titles of musical works and that the searchable vocabulary of the online catalogue often differ from the users’ own.

Full textAbstract:
Despite using high-speed network interconnection
systems like InfiniBand, the communication
overhead for parallel applications, especially
in the area of High-Performance Computing (HPC), is still high. Using large
page frames - so called hugepages in Linux - can
improve the crucial work of registering
communication buffers to the network adapter.
Thus, an InfiniBand driver was modified. But these
hugepages do not only reduce communication costs
but can also improve computation time in a
perceptible manner, e.g. by less TLB misses. To
bypass the outlay of rewriting applications, a
preload library was implemented that is able
to utilize large page frames transparently.
This work also shows benchmark results with these
components and performance improvements of up to
10 %.
