Abstract

Issues concerning the formulation and application of a model of how humans value information are examined. Formulation of a value function is based on research from modelling, value assessment, human information seeking behavior, and human decision making. The proposed function is incorporated into a computer-based fiction retrieval system and evaluated using data from nine searches. Evaluation is based on the ability of an individual's value function to discriminate among novels selected, rejected, and not considered. The results are discussed in terms of both formulation and utilization of a value function as well as the implications for extending the proposed formulation to other information seeking environments

Abstract

This paper traces the history of the concept of intellectual level in cataloging and classification in the United States. Past cataloging codes, subject-heading practice, and classification systems have provided library users with little systematic information concerning the intellectual level or intended audience of works. Reasons for this omission are discussed, and arguments are developed to show that this kind of information would be a useful addition to the catalog record of the present and the future.

Abstract

It is a truism in information science that indexing is associated with 'aboutness', and that index terms that accurately represent what a document is about will serve the needs of the user/searcher well. It is contended in this paper that indexing which is limited to the representation of aboutness serves the novice in a discipline adequately, but does not serve the scholar or researcher, who is concerned with highly specific aspects of or points-of-view on a subject. The linguistic analogs of 'aboutness' and 'aspects' are 'topic' and 'comment' respectively. Serial indexing services deal with topics at varyng levels of specificity, but neglect comment almost entirely. This may explain the underutilization of secondary information services by scholars, as has been repeatedly demonstrated in user studies. It may also account for the incomplete lists of bibliographic references in many research papers. Natural language searching of fulltext databases does not solve this problem, because the aspect of a topic of interest to researchers is often inexpressible in concrete terms. The thesis is illustrated with examples of indexing failures in research projects the author has conducted on a range of linguistic and library-information science topics. Finally, the question of whether indexing can be improved to meet the needs of researchers is examined

Abstract

One knows one is in the presence of "theory" when fundamental questions of a "why" nature are asked. Too often it happens that those involved in the design of bibliographic information systems have no time for brooding. It is thus noteworthy when someone appears an the bibliographic scene who troubles to address, and pursue with philosophic rigor, fundamental questions about the way we organize information. Such a person is Patrick Wilson, formerly philosophy professor at the University of California, Los Angeles, and since 1965, an the faculty of the School of Library and Information Studies, University of California, Berkeley. Bibliographic control is the central concept of Wilson's book Two Kinds of Power. It is represented as a kind of power-a power over knowledge. That power is of two kinds: descriptive and exploitive. Descriptive power is the power to retrieve all writings that satisfy some "evaluatively neutral" description, for instance, all writings by Hobbes or all writings an the subject of eternat recurrence. Descriptive power is achieved insofar as the items in our bibliographic universe are fitted with descriptions and these descriptions are syndetically related. Exploitive power is a less-familiar concept, but it is more important since it can be used to explain why we attempt to order our bibliographic universe in the first place. Exploitive power is the power to obtain the best textual means to an end. Unlike the concept of descriptive power, that of exploitive power has a normative aspect to it. Someone possessing such power would understand the goal of all bibliographic activity; that is, he would understand the diversity of user purposes and the relativity of what is valuable; he would be omniscient both as a bibliographer and as a psychologist. Since exploitive power is ever out of reach, descriptive power is used as a substitute or approximation for it. How adequate this approximation is is the subject of Wilson's book. The particular chapter excerpted in this volume deals with the adequacy of subject access methods. Cutter's statement that one of the objects of a library catalog is to show what the library has an a given subject is generally accepted, as though it were obvious what "being an a given subject" means. It is far from obvious. Wilson challenges the underlying presumption that for any document a heading can be found that is coextensive with its subject. This presumption implies that there is such a thing as the (singular) subject of a document and that it can be identified. But, as Wilson Shows in his elaborate explication, the notion of "subject" is essentially indeterminate, with the consequence that we are limited in our attempts to achieve either descriptive or exploitive power.

Abstract

The fan of past documents may be seen across time as a philosophical "wake," translated documents as a sideways relationship and future documents as another fan spreading forward from a given document (p. 365). The "overlap of reading histories can be used to detect common interests among readers," (p. 365) and readers may be classified accordingly. Finally, Fairthorne rejects the notion of a "general" classification, which he regards as a mirage, to be replaced by a citation-type network to identify classes. An interesting feature of his work lies in his linkage between old and new documents via a bibliographic method-citations, authors' names, imprints, style, and vocabulary - rather than topical (subject) terms. This is an indirect method of creating classes. The subject (aboutness) is conceived as a finite, common sharing of knowledge over time (past, present, and future) as opposed to the more common hierarchy of topics in an infinite schema assumed to be universally useful. Fairthorne, a mathematician by training, is a prolific writer an the foundations of classification and information. His professional career includes work with the Royal Engineers Chemical Warfare Section and the Royal Aircraft Establishment (RAE). He was the founder of the Computing Unit which became the RAE Mathematics Department.
