Abstract

The use of interactive videodiscs for preserving, presenting and retrieving pictorial collections in Australia was pioneered at the New South Wales Government Printing Office, Sydney. This project has now stored some 200.000 historical photographs on interactive videodisc, associated with sophisticated microcomputer data bases using the specially developed Just Image software. Videodisc systems to retrieve pictorial material are being used to preserve and present the pictorial collections of various Australian libraries and museums, and standards for the description and indexing of photographs are being developed.

Abstract

Natural Language Processing (NLP) is one of the principal areas of artificial intelligence. It can be argued that the use of ontologies increases the efficiency of natural language processing. However, most ontologies are built manually and require a lot of work. Thus, the problem of automated ontology replenishment is very relevant. One approach is to develop methods for replenishing ontologies using NLP for specific texts of a certain area. We applied the developed method of replenishing the OntoMathPro mathematical ontology, by extracting new terminology from mathematical documents. We developed a method for processing complex syntactic structures (structures with coordination reduction). The method includes certain rule schemata, conditions under which they are to be applied, and conditions determining the sequence of subtrees for which they are to be performed. In our studies, we investigated typical coordination models for mathematical works and performed experiments with a big mathematical collection.

Abstract

Librarians at the University of the Pacific, California (UOP) designed a replication of an earlier transaction log study carried out at Adelphi University, New York (LRTS 38(1994) no.3, S.293-305). It was hypothesized that library staff would use a feature that allows the searcher to limit a search by location or material type more often than users. It was also hypothesized that library staff and reference librarians would have a higher success rate than public users. The third hypothesis was that UOP users would perform keyword searches more often than library staff. Studies were conducted in 1995 in 1996 to test these hypotheses to provide comparative data on the search styles of users and staff. Searches of the INNOPAC database, using transaction logs, were performed by 4 terminal groups: public users, technical services staff, public services staff, and reference librarians. It was discovered that replicating a study is not nearly as straightforward as was initially thought. It was also found to be surprisingly difficult to compare year to year data at the same institution; primarily due to a continually changing technological environment

Abstract

This study represents an attempt to compare indexing consistency between the catalogers of the National Library of Iran (NLI) on one side and 12 major academic and special libraries located in Tehran on the other. The research findings indicate that in 75% of the libraries the subject inconsistency values are 60% to 85%. In terms of subject classes, the consistency values are 10% to 35.2%, the mean of which is 22.5%. Moreover, the findings show that whenever the number of assigned terms increases, the probability of consistency decreases. This confirms Markey's findings in 1984.

Abstract

This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

Abstract

User studies provide libraries with invaluable insight into their users' information needs and behaviors, allowing them to develop services that correspond to these needs. This insight has become even more important for libraries since the advent of the Internet. The Internet has brought about a development of information technologies and electronic information sources that have had a great impact on both the ways users search for information and the ways libraries manage information. Although humanists represent an important group of users for academic libraries, research studies into their information-seeking behavior since the advent of the Internet have been quite scarce (Ellis & Oldman, 2005) in the past decade. This study presents updated research on a group of humanists, Jewish studies scholars living in Israel, as information users in the digital age based on two categories: (a) the use of formal and informal information channels, and (b) the use of information technologies and their impact on humanistic research.

Abstract

Contribution to a feature on health care within the library systems. Considers the role libraries should play in providing medical information to library users, with particular reference to the Mountain States of the Pacific Northwest USA, in light of a survey of academic libraries in Idaho, Montana and Wyoming: 3 large states with no medical schools or large medical libraries. Results show that academic libraries in all 3 states surveyed are performing a significant function in providing medical information to users, including the general public. Receiving medical questions has become an established part of a reference librarian's routine in academic libraries of all sizes, and such questions are particularly common in smaller libraries, such as community and two year college libraries

Abstract

Internet based electronic resources are growing dramatically but there have been no empirical studies evaluating the impact of e-sources, as a whole, on formal scholarly communication. reports results of an investigation into how much e-sources have been used in formal scholarly communication, using a case study in the area of Library and Information Science (LIS) during the period 1994 to 1996. 4 citation based indicators were used in the study of the impact measurement. Concludes that, compared with the impact of print sources, the impact of e-sources on formal scholarly communication in LIS is small, as measured by e-sources cited, and does not increase significantly by year even though there is observable growth of these impact across the years. It is found that periodical format is related to the rate of citing e-sources, articles are more likely to cite e-sources than are print priodical articles. However, once authors cite electronic resource, there is no significant difference in the number of references per article by periodical format or by year. Suggests that, at this stage, citing e-sources may depend on authors rather than the periodical format in which authors choose to publish

Abstract

The conflict between librarians' ethics and their responsibilities in the process of progressive collection management, which applies the principles of cost accounting to libraries, to call attention to the "bad books" in their collections that are compromised by age, error, abridgement, expurgation, plagiarism, copyright violation, libel, or fraud, is discussed. According to Charles Cutter, notes in catalog records should call attention to the best books but ignore the bad ones. Libraries that can afford to keep their "bad books," however, which often have a valuable second life, must call attention to their intellectual contexts in notes in the catalog records. Michael Bellesiles's Arming America, the most famous case of academic fraud at the turn of the twenty-first century, is used as a test case. Given the bias of content enhancement that automatically pulls content from the Web into library catalogs, catalog notes for "bad books" may be the only way for librarians to uphold their ethical principles regarding collection management while fulfilling their professional responsibilities to their users in calling attention to their "bad books."

Abstract

The evaluation of information retrieval systems is an important yet difficult operation. This paper describes an exploratory evaluation study that takes an interpretive approach to evaluation. The longitudinal study examines evaluation through the information-seeking behaviour of 22 case studies of 'real' users. The eclectic approach to data collection produced behavioral data that is compared with relevance judgements and satisfaction ratings. The study demonstrates considerable variations among the cases, among different evaluation measures within the same case, and among the same measures at different stages within a single case. It is argued that those involved in evaluation should be aware of the difficulties, and base any evaluation on a good understanding of the cases in question

Abstract

This paper describes the combined experience of two research driven case studies that resulted in an Area Studies Virtual Library Catalog (ASVLC). The purpose of the catalog was to provide easy access to, and retrieval of, distributed Internet resources pertaining to four geographic regions: Africa, Latin America, the Middle East and South Asia. The case studies addressed the special considerations encountered in dealing with dynamic Web-based documents in a distributed virtual library. Our experience led to an understanding that collection guidelines for Internet sites must consider various document types available on the Web, document behavior, and document quality. We baselined quantities of Web documents reported by search engines to gain a general concept of document distributed by country, region, and language. Research was performed on Web document persistence to answer questions on catalog maintenance. Findings on document persistence was modified to capture quality indicators about the Web document being described and new metadata forms to better meet the needs of the end user. By incorporating commercial, off-the-shelf software and existing cataloging standards and practices with our findings, we developed a semi-automated methodology for record and catalog creation. Our findings emphasize the differences between the print or paper-based and Web-based electronic documents, the application of the new technologies, and the impact of the findings on creating a virtual library catalog

Abstract

Discusses the basic criteria for comparison of classification for libraries. Identifies a set of intellectual criteria, derived from the general theory of library classification as expounded by Dewey, Bliss, and Ranganathan. Compares LC, DC, and BC in relation criteria namely - order, university, hospitality, adaptability, terminology, relationship, synthesis, notational features - simplicity, brevity, expressiveness, specifity, synonymity, flexibility, correlation, case of use, revision and practical use. Highlights the value of comparative studies among classification schemes

Abstract

Knowledge engineering has been used to design an intelligent interface for the Juris-Data database, 1 of the largest case study databases in France. It was based on the legal classification elaborated by the Juris-Data group to index the cases. The system aims to to help users find the case study most relevant to their own. A methodology for the construction of legal classification of the primary document was designed together with a framework for index construction. This led to the implementation of a Legal Case Studies Engineering Framework based on the accumulated experimentation and the methodologies designed. It consists of a set of computerized tools which support the life cycle of the legal document from their processing by legal experts to their consultation by clients
