Abstract

Spansih subject headings can be used when searching ILLINET Online. Although Spanish language Bilindex subject headings have been available for more than a decade, the library literature has virtually ignored their existence. Provides a brief introduction to these headings, identifies several Illinois libraries which currently assign them, and presents some examples. Surveys various prospects and problems associated with their use

Abstract

Sears List of Subject Headings (Miller and McCarthy 2010), first published in 1923, is now in its 20th edition. Like most subject headings lists, apart from being a list of preferred (and non-preferred) headings, it also provides patterns, clear instructions, and examples for coining new subject headings not explicitly listed. Key headings form a vital part of the system of coining new headings. It is proposed that more key headings should be designated. Some candidate headings are described. One far-reaching provision seems to be the use of a subdivision of a preferred heading with all of its NTs. Thus, every preferred heading is a potential key heading for all of its NTs. This proposal works on the principle that what is true of a class is true of its narrower classes of all types. Applying this principle will enormously enhance the capacity of the List without adding even an iota to its text and size.

Abstract

Scope notes from Library of Congress Subject Headings are examined for 1) adherence to principles enunciated in the introduction to the list; 2) peculiarities of subject headings associated with such notes; 3) the structure of the notes; and 4) typical patterns associated with certain categories of subject headings. Scope notes are shown to enable catalogers to apply subject headings consistently and readers to distinguish related headings knowledgeably.

Abstract

Heterogeneous information environments may cause many problems for knowledge managers. Common characteristics of these environments are complex work practices, non-standard problem solving techniques, and multiple reporting requirements. This paper presents some of the challenges to knowledge management revealed in a 1998 study of county judges and clerks in rural Texas courts. Both types of actors have complex job responsibilities with multiple facets. Their work practices are highly sophisticated, developed over many decades, and not easily transferable to digital environments. State oversight and reporting agencies play important roles in introducing information technologies into local court jurisdictions. The most important element that is missing from such initiatives, however, is a concern for integrated, practice-driven knowledge management processes. It is important to overcome the limited understanding that oversight agencies, technology vendors, and IT consulting firms have of local courts' work practices and knowledge management. To that end, the authors propose a model for integration of knowledge management work practices in local courts into large-scale state information systems. This model emphasizes the need for a holistic, well-integrated view of local practitioners' work and responsibilities

Abstract

In this article, we introduce a new information system evaluation method and report on its application to a collaborative information seeking system, AntWorld. The key innovation of the new method is to use precisely the same group of users who work with the system as judges, a system we call Cross-Evaluation. In the new method, we also propose to assess the system at the level of task completion. The obvious potential limitation of this method is that individuals may be inclined to think more highly of the materials that they themselves have found and are almost certain to think more highly of their own work product than they do of the products built by others. The keys to neutralizing this problem are careful design and a corresponding analytical model based on analysis of variance. We model the several measures of task completion with a linear model of five effects, describing the users who interact with the system, the system used to finish the task, the task itself, the behavior of individuals as judges, and the selfjudgment bias. Our analytical method successfully isolates the effect of each variable. This approach provides a successful model to make concrete the "threerealities" paradigm, which calls for "real tasks," "real users," and "real systems."

Abstract

Spanish is one of the most widely spoken languages in the world and a review of the lists of subject headings in this language reveals numerous efforts over a period of time, usually involving some form of collaboration, but largely isolated from each other. Technological developments suggest that a greater degree of cooperation is now possible and would be beneficial to the international library community if other barriers can be surmounted. The lcsh-es.org project demonstrates this concept in a practical way and suggest a new model for international cooperation in authority control. The site may be accessed at http://lcsh-es.org.

Abstract

Pauline Cochrane and Monika Kirtland's "Critical views of LCSH-Library of Congress Subject Headings: a bibliographic and bibliometric essay" published in 'Cataloging & classification quarterly 1(1982) S.71-93' has been widely cited as a source for discussion and complaints about LCSH. Cochrane and Kirtland cover the literature from 1944-1979. The present work provides a critique of the Cochrane/Kirtland study and a survey of the literature concerning the LCSHs during the 1980s. The classified bibliography is arranged according to the format of the Cochrane/Kirtland study to facilitate comparison. Criticism of LCSH reiterates the same points over and over again, whether it is sparseness, bias or currency of the subject headings. Significant trends which emerged in the 1980s include an increased emphasis on the use of LCSH as an online searching tool, concern for the syndetic structure of LCSH and the role of subdivisions, as well as repeated calls for the development of coherent standards to ensure LCSH evolves and is applied in a consistent manner

Abstract

51 subject searches were performed in an online catalog containing about 4,5 million records. Their success was judges in terms of lists of items, known to be relevant to the various topics, compiled by subject specialists (faculty members or authors of articles in specialized encyclopedias). Many of the items known to be relevant were not retrieved, even in very broad searches that sometimes retrieved several hundred records, and very little could be done to make them retrievable within the constraints of present cataloging practice. Librarians should recognize that library catalogs, as now implemented, offer only the most primitive of subject access and should seek to develop different types of subject access tools. - Vgl auch Letter (B.H. Weinberg) in: LTRS 36(1992) S.123-124.

Abstract

Considers 'about' as it is used in an information retrieval sense, e.g. when an indexer judges that a document is or is not about a given subject. An operational definition of 'about' is given in which it is interpreted in terms of search behaviour. Concludes that 'about' is not the central concept in document retrieval theory. A document retrieval system should provide a search output in which documents are ranked according to the probability that they will satisfy the user's information need rather that according to the degree that they are 'about' the topic. 'Aboutness' is related to satisfaction probability

Abstract

Data contained in a 1982 paper were analyzed in terms of relevance odds of common items retrieved by searching any two content-bearing search fields. While the 1982 study compared the relatice retrieval performance of 7 search fields, the present study shows that duplicate documents retrieval by the use of terms from any two of the fields would have higher odds being judges relevant than those retrieved by only one of the fields. 63 relevance odds were computed using the log cross product technique. The highest relevance odds were associated with common items retrieved from assigned descriptors and from truncated free text terms from either the title or abstract fields; their relevance odds were 19 to 2 in favour of overlaps. Overlap retrieval could be considered a strategy for high precision searching

Abstract

The richness provided in a deep demantic model of text is appealing and yet few such models have been developed. Considers the problems with existing practical natural language processing (NLP) systems and the difficulties in developing such a model. Argues that a possible solution must focus on the reasoning process using knowledge of words rather than the use of other mechanisms and especially those that speed up the pre processing stage. Suggests also that computing representations of text that are transcripts of judges' oral reports on Family Law cases is a challenging text area for these techniques

Abstract

Describes the 26 entires to the 1996 Australian society of Indexers' (AusSI) Prize for Web indexes. Entries showed a variety of approaches to Web indexing and included: linear back-of-book style indexes; annotated bibliographies; Yahoo-style hierachical sites; and beautiful castles with rooms full of links. Entries were judges on ease of use of the index for a novice user, content and breadth of coverage, and usefulness at getting information that could answer questions. The winner was the Australian Parliamentary Library Index by Alan Wilson, an index to the information on the Commonwealth Parliamentary Library's Web site and from othe departments of the Australian Parliament. A brief description of each entrey is given together with its URL and the compiler's email address. All entries can be reached on the Web

Abstract

Two proposals are presented which affect the Library of Congress's subject headings for art: abandonment of the structure used in headings like "Art, French" and assignment of genre headings for some types of reproductions of an artist's work.

Abstract

The Technical Services Committee of the Women's Studies Section, Association of College and Research Libraries, investigated the assignment of subject headings (LCSH) to core works in women's studies. Annotations for the works were compared with subject headings on OCLC cataloguing copy, mainly created by the Library of Congress. Identifies inadequates and traces them to 3 sources: inadequacies in terminology (sexist langugae, limited and biased concepts and imprecise headings); complexities of assigning headings in interdisciplinary and / or emerging fields; and standard cataloguing practices. Lists sample concepts and existing established LCSH missing lacking in bibliographical records and sample concepts lacking adequate established subject headings. Presents recommendations for remedying these problems

Abstract

Many kinds of structure can be discerned in the headings and rules governing the Library of Congress Subject Headings. By addressing these structures at different levels, librarians can develop different approaches to the machine-assisted validation of subject headings, from the checking of individual words to the validation of complex forms of heading/subdivision compatibility. Using computer programs to assist with maintenance of subject headings is becoming increasingly necessary as technical services librarians strive to create consistent and useful patterns of subject collocation in library catalogs
