Here is an excerpt from the book's Preface by the author, William Arms, dated June 2005: This online edition of Digital Libraries is an updated version of the book of the same name published by the M.I.T. Press in January 2000. I am extremely grateful to the press for giving me permission to place it online even while the book is still in print. The field of Digital Libraries is moving rapidly. Most of this book was written in 1998 and many sections are now seriously out of date. In particular:
* In the few years since the book was written, there have been some major developments. Important topics that need to be updated or included for the first time include the emergence of XML, the dominance of Google, reference linking, the Internet Archive, the Open Archives Initiative, and many more.
* Numerous details need to be brought up to date.
* A few projects have come to an end and a few topics have proved to be less important than expected. They need to be deleted or give less emphasis.
* The book does not have a bibliography, because, only a few years ago, nobody had confidence in the longevity of URLs. Now it is clear that many online collections are managed for the long term and can be cited with confidence.
* Our understanding has developed. In some aspects, uncertainties have been resolved; in others the complexities seem to have grown. There is less need to be an advocate for digital libraries.
Despite being out of date in these ways, the major themes and much of the material remains valuable. In particular, the importance of understanding the human and social context while carrying out technical work remains the heart of all work in digital libraries."

Phiri, Lighton. "Simple Digital Libraries." Thesis, University of Cape Town, 2013. http://pubs.cs.uct.ac.za/archive/00000887/.
Full textAbstract:
The design of Digital Library Systems (DLSes) has evolved overtime, both in sophistication and complexity, to complement the complex nature and sheer size of digital content being curated. However, there is also a growing demand from content curators, with relatively small-size collections, for simpler and more manageable tools and services to manage their content. The reasons for this particular need are driven by the assumption that simplicity and manageability might ultimately translate to lower costs of maintenance of such systems.
This research proposes and advocates for a minimalist and simplistic approach to the overall design of DLSes. It is hypothesised that Digital Library (DL) tools and services based on such designs could potentially be easy to use and manage.
A meta-analysis of existing DL and non-DL tools was conducted to aid the derivation of design principles for simple DLSes. The desig n principles were then mapped to design decisions applied to the design of a prototype simple repository. In order to assess the effectiveness of the simple repository design, two real-world case study collections were implemented based on the design. In addition, a developer-oriented study was conducted using one of the case study collections to evaluate the simplicity and ease of use of the prototype system. Furthermore, performance experiments were conducted to establish the extent to which such a simple design approach would scale and also establish comparative advantages to existing designs.
In general, the study outlined some possible implications of simplifying DLS design; specifically the results from the developer-oriented user study indicate that simplicity in the design of the DLS repository sub-layer does not severely impact the interaction between the service sub-layer and the repository sub-layer. Furthermore, the scalability experiments indicate that desirable performance results for small- and medium-sized collections are attainable.
The practical implication of the proposed design approach is two-fold: firstly the minimalistic design has the potential to be used to design simple and yet easy to use tools with comparable features to those exhibited by well-established DL tools; and secondly, the principled design approach has the potential to be applied to the design of non-DL application domains.

Digital libraries are an integration of complex computer and information systems that could benefit from a formal approach to design. There are various design aspects to consider in a digital library; a crucial aspect is security. Security often is a requirement in digital libraries that should be considered during the design process and not as an add-on feature.
5S provides a DL modeling framework, to define all the aspects of a digital library. It covers the different formats and types of digital objects stored, how they are grouped and organized, what sequence of operations occur in the digital library, how the objects will be represented, and who is part of the digital library community. However, the 5S descriptive language (5SL) previously did not cover the essential security requirements in a digital library.
The goal of this research is to extend the 5S framework to describe the security requirements in digital library. An XML schema was developed to describe the necessary security requirements in a digital library, and some of the essential features of the digital library design. This work explains the key security requirements needed in a digital library from the 5S perspective and how the framework can be extended to include these requirements. The extended 5SL was applied to a case study on the Egyptian University Libraries Consortium.Master of Science

Full textAbstract:
Digital Libraries (DLs) are software systems specifically designed to assist users in information seeking activities. Stemming from the intersection of library sciences and computer networking, traditional DL systems impose library philosophies of structure and management on the sprawling collections of data that are made possible through the Internet.
DLs evolve to keep pace with innovation on the Internet so there is little standardization in the architecture of such systems. However, in attempting to provide users with the highest possible levels of service with the minimum possible effort, many systems work collaboratively with others, e.g., meta-search engines. This type of system interoperability is encouraged by the emergence of simple data transfer protocols such as the Open Archives Initiative?s Protocol for Metadata Harvesting (OAI-PMH).
Open Digital Libraries are an extension of the work of the OAI. It is proposed in this dissertation that the philosophy and approach adopted by the OAI can easily be extended to support inter-component interaction within a componentized DL. In particular, DLs can be built by connecting small components that communicate through a family of lightweight protocols, using XML as the data interchange mechanism. In order to test the feasibility of this, a set of protocols was designed based on a generalization of the work of the OAI. Components adhering to these protocols were implemented and integrated into production and research DLs. These systems were then evaluated for simplicity, reusability, and performance.
On the whole, this study has shown promise in the approach of applying the fundamental concepts of the OAI protocol to the task of DL component design and implementation. Further, it has shown the feasibility of building componentized DL systems using techniques that are a precursor to the Web Services approach to system design.Ph. D.

Full textAbstract:
The motivation for this work is based on two recognized research issues for digital libraries. One is the need for interlinked and semantically rich information spaces where relationship information is of particular importance. The other is the serviceoriented architecture of digital libraries. The digital libraries of the future will consist of smaller and independent systems that each will provide different functionality and access to different contents.
This work defines and explores a service for managing and using explicit relationships – the Digital Library Link Service. The service implements an instance-oriented approach to relationships that enables any kind of typed relationship to be created among the information objects of digital libraries. The service can be used to create consistent information spaces on top of digital library repositories and enables an associative organization and retrieval of information objects.
This work shows that the use of a fine-grained relationship model implemented as distributed objects enables distribution of the relationship network while still being able to support constraints and maintain consistency. The cost of this, however, is a complexity that can reduce performance and scalability due to the call latency of network communication. A prototype is developed that utilizes caching in order to solve this. Tests conducted show that this technique significantly contributes to the scalability and efficiency. This is particularly important when the relationship information is distributed across different processes with high calllatency in between.
The work further presents a prototype application for enhancing bibliographic catalogues with the rich set of relationship types defined in the bibliographic information model proposed by the International Federation of Library Associations and Institutions – the FRBR model. The Digital Library Link Service is used to implement an index that facilitates the navigation of bibliographic relationships in order to explore bibliographic entities along the paths laid out by the FRBR model. This demonstrates the applicability of the service as a flexible tool for associative organization of information objects.
The main applications of the service are limited to systems with a relaxed requirement in terms of automatic processing of larger sets of relationships. The main access paradigm explored for interacting with relationships is by navigation. The need for automatic and efficient processing of a large relationship network, e.g. for the purpose of indexing, can be supported by extending the system with additional functionality. Another recognized problem is that the use of CORBA references to address long-term persistent information can cause referential integrity problems. One possible way to solve this is to assigning objects globally unique identifiers that later can be used to recover from referential integrity problems.

The quality of metadata in a digital library is an important factor in ensuring access for end-users. Several studies have tried to define quality frameworks and assess metadata but there is little user feedback about these in the literature. As collections grow in size maintaining quality through manual methods becomes increasingly difficult for repository managers. This research presents the design and implementation of a web-based metadata analysis tool for digital repositories. The tool is built as an extension to the Greenstone3 digital library software. We present examples of the tool in use on real-world data and provide feedback from repository managers. The evidence from our studies shows that automated quality analysis tools are useful and valued service for digital libraries.

Full textAbstract:
This thesis describes the design, development, and evaluation of a social digital library to support users in finding information from a user-based point of view. This particular research project has been motivated by the fact that there has been very little research on the social features in digital library interfaces. This research aims to design a novel digital library interface by applying the concepts of social features to digital libraries. Also, the thesis investigates whether the functionalities in the social digital library help participants to accomplish different task types with minimum effort. Social features here refers to clustering users' interacting in a virtual community along with social information such as reviews, the number of recommendations and items/ viewed items by other people. In order to gain an insight into the social features that are useful for users to compt~te search tasks, I began with the development of The Victorian Times Digital Library by using PHP & MySQL. Initial design interfaces were tested by usability tests in order to overcome usability problems. Based on participants' feedback, the chosen features were presented in the social digital library and represented in different screens. These interfaces were then evaluated by several usability tests using an iterative design approach. Also during an iterative phase of design, the interfaces were revised based on Information Foraging Theory in order to increase strong information scent. The final version of the social digital library was then evaluated against a conventional interface in an effectiveness test. I performed an experimental study to examine the use of features in digital libraries to perform the tasks. A total of twenty four participants were recruited to perform various tasks on both interfaces and to rate their preferences. The outcomes of the effectiveness test were positive, with half of participants (12 out of 24) preferring the social interface and the rest of participants preferring the traditional one. Also, the results showed that the social digital library was able to help participants to accomplish different types of task with minimum time and effort. This was considered as a good result given the quality feedback from the participants. Also, some of findings emphasized the importance of social activities and look and feel over a set of social features.

Information management systems (digital libraries/repositories, learning management systems, content management systems) provide key technologies for the storage, preservation and dissemination of knowledge in its various forms, such as research documents, theses and dissertations, cultural heritage documents and audio files. These systems can make use of cloud computing to achieve high levels of scalability, while making services accessible to all at reasonable infrastructure costs and on-demand. This research aims to develop techniques for building scalable digital information management systems based on efficient and on-demand use of generic grid-based technologies such as cloud computing. In particular, this study explores the use of existing cloud computing resources offered by some popular cloud computing vendors such as Amazon Web Services. This involves making use of Amazon Simple Storage Service (Amazon S3) to store large and increasing volumes of data, Amazon Elastic Compute Cloud (Amazon EC2) to provide the required computational power and Amazon SimpleDB for querying and data indexing on Amazon S3. A proof-of-concept application comprising typical digital library services was developed and deployed in the cloud environment and evaluated for scalability when the demand for more data and services increases. The results from the evaluation show that it is possible to adopt cloud computing for digital libraries in addressing issues of massive data handling and dealing with large numbers of concurrent requests. Existing digital library systems could be migrated and deployed into the cloud.

Artificial Intelligence Lab, Department of MIS, University of ArizonaAs new and emerging classes of information systems applications the applications become more overwhelming, pressing, and diverse, several well-known information retrieval (IR) problems have become even more urgent in this “network-centric” information age. Information overload, a result of the ease of information creation and rendering via the Internet and the World Wide Web, has become more evident in people’s lives. Significant variations of database formats and structures, the richness of information media, and an abundance of multilingual information content also have created severe information interoperability problems-structural interoperability, media interoperability, and multilingual interoperability. The conventional approaches to addressing information overload and information interoperability problems are manual in nature, requiring human experts as information intermediaries to create knowledge structures and/or ontologies. As information content and collections become even larger and more dynamic, we believe a systemaided bottom-up artificial intelligence (AI) approach is needed. By applying scalable techniques developed in various AI subareas such as image segmentation and indexing, voice recognition, natural language processing, neural networks, machine learning, clustering and categorization, and intelligent agents, we can provide an alternative system-aided approach to addressing both information overload and information interoperability.

Artificial Intelligence Lab, Department of MIS, University of ArizonaIn this era of the Internet and the World Wide Web, the long-time topic of digital libraries has suddenly become white hot. As the Internet expands, particularly the WWW, more people are recognizing the need to search indexed collections. Digital library research projects thus have a common theme of bringing search to the Net. This is why the US government made digital libraries the flagship research effort for the National Information Infrastructure (NII), which seeks to bring the highways of knowledge to every American. As a result, the four-year, multiagency DLI was funded with roughly $1 million per year for each project (see the "Agency perspectives" sidebar). Six projects (chosen from 73 proposals) are involved in the DLI, which is sponsored by the National Science Foundation, Advanced Research Projects Agency, and the National Aeronautics and Space Administration. This issue of Computer includes project reports from these six university sites: Carnegie Mellon University, University of California at Berkeley, University of California at Santa Barbara, University of Illinois at Urbana-Champaign, University of Michigan, and Stanford University.

In the near future, users will have access to a vast number of digital libraries. For a given information need and limited resources, there is the problem of selecting those libraries which produce an overall optimum answer. This resource discovery problem is additionally complicated by the diversity of the sources, e.g. with respect to media, document formats, indexing methods, database schemas and protocols. Once a set of digital libraries has been selected, the collection fusion problem deals with the problem of merging the answers of these libraries in order to get a high retrieval quality. This paper describes the specific problems and gives an overview on the solutions that have been developed so far.

The tool generates summaries, nouns, and non phrases for use as metadata for searching and browsing digital collections. Digital collections of newspapers, PDFs, and eBooks were created with summary metadata. PDF documents were processed the fastest at 1.8 MB/hr, followed by the newspapers at 1.3 MB/hr, with eBooks being the slowest at 0.9 MV/hr. Qualitative analysis on four genres: newspaper, M.Sc. thesis, novel, and poetry, revealed narrative newspapers were most suitable for automatically generated summarization. The other genres suffered from incoherence and information loss. Overall, summaries for digital collections are suitable when used with newspaper documents and unsuitable for other genres.xiii, 142 leaves ; 28 cm.

Full textAbstract:
Subject specialists and researchers often face the problem of identifying authoritative collections: those directly about their topic of interest, to which they regularly return to satisfy related information needs or monitor for new material. Discovery of such collections is often incidental or relies on suggestions from domain experts. Services such as general purpose search engines and repository directories offer limited support for this search task. As such, there is a clear need for a search service specifically to assist users in finding collections that can serve both their current and future information needs; we refer to this task herein as collection suggestion. However, developing an effective search service of this kind requires fundamental research. There are several preconditions that should be addressed; it is these that form the focus of this thesis. We summarise these areas as follows. An effective search service calls for an appropriate algorithm; in this instance, an algorithm for ranking collections with respect to the user's query. To this end, we investigate the applicability of existing algorithms, from relevant domains (collection selection and query performance prediction), to collection suggestion. In addition, towards identifying an optimal algorithm for a collection suggestion search service, we specify and test a new algorithm (and several alternative variants), designed specifically for this task. The requirement of an appropriate algorithm presents the question of how we evaluate the effectiveness of an algorithm. We have formulated a methodology (comprising evaluation strategies and performance measures) and developed apparatus for evaluating algorithms, with respect to collection suggestion. As far as possible, we have drawn on and extended established algorithm evaluation techniques, to ensure our work follows the expectations of information retrieval research. Our empirical work is conducted over several synthetic and realistic test data sets: we use established data sets built from the TREC document corpus, in addition to data sets of our own compilation, comprising data from real repositories. This combination of test data types ensures a rigorous test environment for algorithms. Over our test environment, we have found three algorithms to be potentially suitable for application in a collection suggestion search service. One collection selection algorithm (CORI), and two variants of our own algorithm were shown to have strong and consistent performance, across the range of test data sets and performance measures used.

Full textAbstract:
Digital Libraries (DL) generally contain a collection of independently maintained data sets, in different formats, which may be queried by geographically dispersed users. The general problem of managing such large digital data archives is particularly challenging when the system must cope with data which is processed on demand. This dissertation proposes a Multi-Agent System (MAS) architecture for the utilisation of an active DL that provides computing services in addition to data-retrieval services, so that users can initiate computing jobs on remote supercomputers for processing, mining, and filtering of the data in the library. The system architecture is based on a collaborative set of agents, where each agent undertakes a pre-defined role, and is responsible for offering a particular type of service. The integration of services is based on a user defined query which can range in complexity from simple queries, to specialised algorithms which are transmitted to image processing archives as mobile agents. The proposed architecture enables new information sources and services to be integrated into the system dynamically, supports autonomous and dynamic on-demand data processing based on collaboration between agents, capable of handling a large number of concurrent users. Focus is based on the management of mobile agents which roam through the servers that constitute the DL to serve user queries. A new load balancing scheme is proposed for managing agent load among the available servers, based on the system state information and predictions about lifetime of agent tasks and server status. The system architecture is further extended by defining a gateway to provide interoperability with other heterogeneous agent-based systems. Interoperability in this sense enables agents from different types of platforms to communicate between themselves and use services provided by other systems. The novelty of the proposed gateway approach lies in the ability to adapt an existing legacy system for use with the agent-based approach (and one that adheres to FIPA standards). A prototype has been developed as a proof-of-concept to outline the principles and ideas involved, with reference to the Synthetic Aperture Radar Atlas (SARA) DL composed of multi-spectral remote-sensing imagery of the Earth. Although, the work presented in this dissertation has been evaluated in the context of SARA DL, the proposed techniques suggest useful guidelines that may be employed by other active archival systems.

The high demand for building digital libraries by non-experts requires a simplified modeling process and rapid generation of digital libraries. To enable rapid generation, digital libraries should be modeled with descriptive languages. A visual modeling tool would be helpful to non-experts so they may model a digital library without knowing the theoretical foundations and the syntactical details of the descriptive language.
In this thesis, we describe the design and implementation of a domain-specific visual modeling tool, 5SGraph, aimed at modeling digital libraries. 5SGraph is based on a metamodel that describes digital libraries using the 5S theory. The output from 5SGraph is a digital library model that is an instance of the metamodel, expressed in the 5S description language (5SL). 5SGraph presents the metamodel in a structured toolbox, and provides a top-down visual building environment for designers. The visual proximity of the metamodel and instance model facilitates requirements gathering and simplifies the modeling process. Furthermore, 5SGraph maintains semantic constraints specified by the 5S metamodel and enforces these constraints over the instance model to ensure semantic consistency and correctness. 5SGraph enables component reuse to reduce the time and efforts of designers. The results from a pilot usability test confirm the usefulness of 5SGraph.Master of Science

Full textAbstract:
With the rapid growth of the World Wide Web and online information services, more and more information is available and accessible online. Automatic summarization is an indispensable solution to reduce the information overload problem. Multi-document summarization is useful to provide an overview of a topic and allow users to zoom in for more details on aspects of interest. This paper reports three types of multi-document summaries generated for a set of research abstracts, using different summarization approaches: a sentence-based summary generated by a MEAD summarization system that extracts important sentences using various features, another sentence-based summary generated by extracting research objective sentences, and a variable-based summary focusing on research concepts and relationships. A user evaluation was carried out to compare the three types of summaries. The evaluation results indicated that the majority of users (70%) preferred the variable-based summary, while 55% of the users preferred the research objective summary, and only 25% preferred the MEAD summary.

This dissertation addresses the problem of the «Digital Library»
from the point of view of the «Traditional Library». The work comprises an
analytical approach to the problem, being proposed a model for the «Digital

analysed for the cases of the specialized library and the deposit library, when
facing the problem of the digital publishing. As a result, it is proposed a
strategy for the deposit library based on the identification of scenarios and
publication genres. As a consequence of this process, there were also
identified and analysed new problem, such as the new concept of agent, the
relationship of the concept URN identifiers? space with the problem, and the
problem of the metadata. Metadata is now a new concern for the «Digital

of the interoperability.O trabalho desenvolvido nesta dissertação gira em torno do termo «Biblioteca Digital» e daquilo que ele poderá significar quando considerado segundo os requisitos da «Biblioteca Tradicional». O resultado consistiu numa abordagem analítica ao problema, propondo-se um modelo para a «Biblioteca Digital» gerado segundo a perspectiva da «Biblioteca Tradicional» quando confrontada com o novo paradigma tecnológico emergente. Este modelo é analisado para os casos da biblioteca especializada e da biblioteca de depósito quando posta perante o problema do depósito de publicações digitais, propondo-se ainda uma estratégia para a mesma baseada na identificação de cenários e géneros de publicações. Como consequência são ainda identificados e analisados novos problemas, especialmente os do agente enquanto novo conceito, a relação do problema com o caso do espaço de identificadores URN, e o problema da metadata. Conclui-se ainda ser esta agora uma nova preocupação na «Biblioteca Digital», de onde resultam novos requisitos e cenários que nos conduzem ao problema da inter-operação.

Full textAbstract:
This master thesis aims to critically analyze the state of digital libraries in Swedish academic libraries. With the branching theory of sense-making and the methodology of DELOS and IFLA/UNESCOs digital library manifestos, this thesis hopes to bring to light how far Swedish academic libraries have progressed. By accumulating quantitative data encompassing all digital academic libraries in Sweden, and qualitative data from a select few, conclusions regarding the aforementioned are drawn. Focusing on content analysis, this thesis analyzed the different components that can be said to constitute the digital library and compared them to the different manifestos that dictate what a digital library can be said to consist of. By employing the elusive sense-making theory as a general modus of mind, one can begin to understand thought-making processes behind the tapping of digital library resources. Results from this thesis found that some functions and components are present within all academic libraries in Sweden, but that the digital library primarily tends to focus on resource acquisition and not so much on resource presentation. User environments are not prioritized. Different aspects are presented in regards to mobile optimization, social media, information organization, information design etc. This is a two years master’s thesis in Archive, Library and Museum studies.Den här masteruppsatsen syftar till att undersöka digitala bibliotek och digitala miljöer på svenska högskole- och universitetsbibliotek. Med sense-making som huvudsaklig teoretiskt ramverk och DELOS och IFLA/UNESCOs olika manifest gällande digitala bibliotek hoppas uppsatsen visa hur långt svenska bibliotek har kommit i relation till det digitala. Via samlandet av kvantitativ data från alla svenska akademiska bibliotek, och kvalitativ data från ett fåtal utvalda, kommer uppsatsen till diverse slutsatser. Med fokus på innehåll och funktion så undersöker uppsatsen vilka komponenter som kan sägas utgöra det digitala biblioteket i jämförelse med manifesten och deras ideala digitala bibliotek. Med hjälp av sense-making kan man få en förståelse för tankessättet och hur användare angriper de digitala resurserna. Resultaten från uppsatsen visade att det finns en viss grad av framsteg och utveckling som alla bibliotek har nått, men att den digitala satsningen oftast endast inbegriper samlandet av resurser och uppbyggandet av databaser snarare än presentation och design. Miljöer som gör att användarna frodas prioriteras ofta bort. Olika aspekter presenteras i relation till detta såsom mobil-optimering, sociala medier, informationsorganisation, informationsdesign osv. Det här är en tvåårig masteruppsats inom Arkiv, Bibliotek och museum.

The difference between a digital library and a library with which a digital reference service is affiliated is discussed, and digital reference in these contexts is defined. There are several issues involved in integrating digital reference service into a digital library environment, but two that are unique to the intersection between digital libraries and digital reference: collection development of previously-answered questions, and presentation of specialized subsets of the materials in the digital library's collection. These two issues are explored.

follow up on their progress. Additionally, we interviewed 18 key informants, including archivists
and librarians. In round 3 the authors will each conduct one case study drawn from the survey
participants in rounds 1 and 2. By the end of the three rounds, the authors will have studied a
continuum of activities (over a six-year period) that constitutes a range of digital preservation
strategies. The study will have charted the change in technological developments over this periodâ
developments that have occurred in our survey institutions to meet the requirements of their
mandates to preserve digital content for as long as needed.

Artificial Intelligence Lab, Department of MIS, University of ArizonaDigital libraries of geo-spatial multimedia content are currently deficient in providing fuzzy, concept-based retrieval mechanisms to users. The main challenge is that indexing and thesaurus creation are extremely laborintensive processes for text documents and especially for images. Recently, 800,000 declassified satellite photographs were made available by the United States Geological Survey. Additionally, millions of satellite and aerial photographs are archived in national and local map libraries. Such enormous collections make human indexing and thesaurus generation methods impossible to utilize. In this article we propose a scalable method to automatically generate visual thesauri of large collections of geo-spatial media using fuzzy, unsupervised machine-learning techniques.

Full textAbstract:
The development of information and communication technologies, and wide spread of the Internet and its associated technologies have brought about tremendous changes in the reference department of academic libraries, and in the attitudes and expectations of both information professionals and users. Many academic libraries across the globe have embraced Web technologies to fulfil users reference needs in a digital environment. This study aimed to investigate and analyse digital reference services (DRS) in university libraries in Pakistan. It focused on the nature and level of DRS, technologies used for the provision of the service, usage, staffing, marketing, funding, ICT infrastructure available for the service, and looked at the issues faced by academic libraries in implementing and managing the service. A mixed methods research approach combining both quantitative and qualitative methods was employed to achieve the aim and objectives of the study. The quantitative data for the study were collected through an online survey. A total of eighty five university libraries (both in public and private sectors) from all the four provinces, the federal capital and Azad Jammu & Kashmir participated in the survey. The quantitative data were supplemented by the qualitative data which were gathered through semi-structured interviews with the heads of fifteen leading university libraries. Findings suggest that DRS is at an early development stage in university libraries in Pakistan, with a small number of libraries offering the service. Most of the academic libraries which have implemented this cutting-edge service, are large libraries equipped with good human and technological resources. The libraries have mostly developed asynchronous digital reference systems by employing e-mail and web forms. The usage of the service is lower than that of in-person reference in academic libraries due to factors, such as libraries failure to effectively market the service, lack of ICT skills among users, lack of ICT facilities available for users. It was found that the libraries lack skilled and competent LIS professionals to staff the service. Factors contributing to the scarcity of skilled human resources in academic libraries include the lack of in-house training for DRS, shortage of continuing professional development courses in the country, and deficiencies in LIS curricula offered by the country s library schools. A number of issues which affect the implementation and management of DRS in academic libraries have been identified. They include: scarcity of competent human resources; access to appropriate digital resources; unavailability of suitable software for DRS; financial constraints; lack of ICT facilities; absence of a digital reference policy; lack of ICT application; paucity of resources; electricity supply; inadequate physical facilities; lack of local research and literature on DRS.

Full textAbstract:
Some classes of Internet users have specific information needs and specialized information-seeking behaviors. For example, educators who are designing a course might create a syllabus, recommend books, create lecture slides, and use tools as lecture aid. All of these resources are available online, but are scattered across a large number of websites. Collecting, linking, and presenting the disparate items related to a given course topic within a digital library will help educators in finding quality educational material.
Content quality is important for users. The results of popular search engines typically fail to reflect community input regarding quality of the content. To disseminate information related to the quality of available resources, users need a common place to meet and share their experiences. Online communities can support knowledge-sharing practices (e.g., reviews, ratings).
We focus on finding the information needs of educators and helping users to identify potentially useful resources within an educational digital library. This research builds upon the existing 5S digital library (DL) framework. We extend core DL services (e.g., index, search, browse) to include information from latent user groups. We propose a formal definition for the next generation of educational digital libraries. We extend one aspect of this definition to study methods that incorporate collective knowledge within the DL framework. We introduce the concept of deduced social network (DSN) - a network that uses navigation history to deduce connections that are prevalent in an educational digital library. Knowledge gained from the DSN can be used to tailor DL services so as to guide users through the vast information space of educational digital libraries. As our testing ground, we use the AlgoViz and Ensemble portals, both of which have large collections of educational resources and seek to support online communities. We developed two applications, ranking of search results and recommendation, that use the information derived from DSNs. The revised ranking system incorporates social trends into the system, whereas the recommendation system assigns users to a specific group for content recommendation. Both applications show enhanced performance when DSN-derived information is incorporated.Ph. D.

We formalize the digital library (DL) integration problem and propose an overall approach based on the 5S (Streams, Structures, Spaces, Scenarios, and Societies) framework. We then apply that framework to integrate domain-specific (archaeological) DLs, illustrating our solutions for key problems in DL integration. An integrated Archaeological DL, ETANA-DL, is used as a case study to justify and evaluate our DL integration approach. We develop a minimum metamodel for archaeological DLs within the 5S theory. We implement the 5SSuite toolkit set to cover the process of union DL generation, including requirements gathering, conceptual modeling, rapid prototyping, and code generation. 5SSuite consists of 5SGraph, 5SGen, and SchemaMapper, which plays an important role during integration. SchemaMapper, a visual mapping tool, maps the schema of diverse DLs into a global schema for a union DL and generates a wrapper for each individual DL. Each wrapper transforms the metadata catalog of its DL to one conforming to the global schema. The converted catalogs are stored in the union catalog, so that the union DL has a global metadata format and union catalog. We also propose a formal approach to DL exploring services for integrated DLs based on 5S, which provides a systematic and functional method to design and implement DL exploring services. Finally, we propose a DL success model to assess integrated DLs from the perspective of DL end users by integrating 5S theory with diverse research on information systems success and adoption models, and information-seeking behavior models.Ph.

Full textAbstract:
This thesis presents an empirical investigation of the problems of including pictorial digital art in the context of Digital Libraries (DLs). The rational for this work is that digital art material is a significant source of learning and research, provided that it is systematically collected and maintained in structured electronic repositories. The thesis addresses a fundamental question: How to provide description and retrieval services, which are based on the needs of digital art user communities? This raises three research issues. One is the need to combine DL collections into meaningful and functional content. The second is the importance of a user-oriented approach to designing and developing Digital Libraries. The third is the requirement for continuing access to digital art as a record of modern culture. These questions are explored through a needs assessment targeted to Arts & Humanities scholars, digital artists and representatives of the DL community. A data collection methodology is developed, based on the principles of Social Informatics and a case study of evaluation efforts in extant projects. The results from this process demonstrate that the scholarly value of digital art can be established by aggregating material from various repositories into a unified dataset. The results also identify specific documentation and retrieval issues deriving from inclusion of digital art in a DL environment that necessitate further investigation. To this end, a review of sixteen digital art online resources is conducted which reveals ad-hoc collection strategies and metadata deficiencies. The work presents a prototype Digital Library for enhancing the educational outcome of digital art. The application is used as an implementation platform for material aggregation and augmented documentation through the Media Art Notation System (MANS). The summative evaluation findings confirm that the suggested solutions are highly rated by the targeted audiences. The thesis makes a contribution to academic knowledge in situating the representation of digital art within modern society. By critically examining the unique requirements of this material using the resources of social theory, the thesis represents a contemporary and pragmatic perspective on digital media art. In a well-structured Digital Library, the scholarly potential of digital art is much greater than the currently employed ad-hoc context. This work offers a sustained reflection and a roadmap for selecting and consistently applying a strategy that aims to continually improve the quality of digital art provision.

The amount of digital content produced at academic research institutions is large, and libraries and archives at these institutions have a responsibility to bring this digital material under curatorial control in order to manage and preserve it over time. But this is a daunting task with few proven models, requiring new technology, policies, procedures, core staff competencies, and cost models. The MIT Libraries are working with the DSpace(TM) open-source digital repository platform to explore the problem of capturing research and teaching material in any digital format and preserving it over time. By collaborating on this problem with other research institutions using the DSpace platform in the United States, the United Kingdom, Europe, and other parts of the world, as well as with other important efforts in the digital preservation arena, we are beginning to see ways of managing arbitrary digital content that might make digital preservation an achievable goal.Page image PDF

Poster paperThe advent of Information and communication technology has revolutionized the way information was accessed and disseminated; one of the most visible changes came in the arena of librarianship. Suddenly, the idea of easy, fingertip access to information became widely prevalent and phrases like "virtual library," "electronic library," "library without walls" and, most recently, "digital library," very popular. However, this produced a new and confusing bog of electronic "stuff" that is hard to find, hard to use, buried in restrictions, unreliable in content, and useless to researchers baffled by bad choices of material for expensive digitisation investments? Now, the question is sustaining digital libraries will require overcoming substantial uncertainties about long-term preservation, institutional commitments, and financing. AND here lies the challenge for the digital librarian!!!! Playing the balancing act between management, fast changing needs of the user community and ever changing information storage media and technologies.

Artificial Intelligence Lab, Department of MIS, Univeristy of ArizonaIn an effort to assist medical researchers and professionals in accessing information necessary for their work, the A1 Lab at the University of Arizona is investigating the use of a natural language processing (NLP) technique called noun phrasing. The goal of this research is to determine whether noun phrasing could be a viable technique to include in medical information retrieval applications. Four noun phrase generation tools were evaluated as to their ability to isolate noun phrases from medical journal abstracts. Tests were conducted using the National Cancer Institute's CANCERLIT database. The NLP tools evaluated were Massachusetts Institute of Technology's (MIT's) Chopper, The University of Arizona's Automatic Indexer, Lingsoft's NPtool, and The University of Arizona's AZ Noun Phraser. In addition, the National Library of Medicine's SPECIALIST Lexicon was incorporated into two versions of the AZ Noun Phraser to be evaluated against the other tools as well as a nonaugmented version of the AZ Noun Phraser. Using the metrics relative subject recall and precision, our results show that, with the exception of Chopper, the phrasing tools were fairly comparable in recall and precision. It was also shown that augmenting the AZ Noun Phraser by including the SPECIALIST Lexicon from the National Library of Medicine resulted in improved recall and precision.

Despite the fact that many Digital Libraries (DLs) are available on the Internet, users cannot effectively use them because of inadequate functionality, deficient visualisation and insufficient integration of different DLs. In the framework of this project we develop a user-oriented access system for DLs which overcomes these drawbacks. Based on experiences from the librarian area, higher functions to assist proved search strategies will be implemented. Different DLs will be tightly integrated, so that system-wide search and navigation is possible. The system will be adaptive towards different user wishes, regarding preferences concerning content and system involvement.

Advances in scientific data management, discovery, dissemination, and sharing are changing the manner in which scientific studies are being conducted and repurposed. Data-intensive scientific practices increasingly require data management related services not available in existing digital libraries. Complicating the issue are the diversity of functional requirements and content in scientific domains as well as scientists' lack of expertise in information and library sciences.
Researchers that utilize simulation and experimentation systems need digital libraries to maintain datasets, input configurations, results, analyses, and related documents. A digital library may be integrated with simulation infrastructures to provide automated support for research components, e.g., simulation interfaces to models, data warehouses, simulation applications, computational resources, and storage systems. Managing and provisioning simulation content allows streamlined experimentation, collaboration, discovery, and content reuse within a simulation community. Formal definitions of this class of digital libraries provide a foundation for producing a software toolkit and the semi-automated generation of digital library instances.
We present a generic, component-based SIMulation-supporting Digital Library (SimDL) framework. The framework is formally described and provides a deployable set of domain-free services, schema-based domain knowledge representations, and extensible lower and higher level service abstractions. Services in SimDL are specialized for semi-structured simulation content and large-scale data producing infrastructures, as exemplified in data storage, indexing, and retrieval service implementations. Contributions to the scientific community include previously unavailable simulation-specific services, e.g., incentivizing public contributions, semi-automated content curating, and memoizing simulation-generated data products. The practicality of SimDL is demonstrated through several case studies in computational epidemiology and network science as well as performance evaluations.Ph. D.
