Abstract

Why devote an ARIST chapter to scholarly communication and bibliometrics, and why now? Bibliometrics already is a frequently covered ARIST topic, with chapters such as that by White and McCain (1989) on bibliometrics generally, White and McCain (1997) on visualization of literatures, Wilson and Hood (2001) on informetric laws, and Tabah (2001) on literature dynamics. Similarly, scholarly communication has been addressed in other ARIST chapters such as Bishop and Star (1996) on social informatics and digital libraries, Schamber (1994) on relevance and information behavior, and many earlier chapters on information needs and uses. More than a decade ago, the first author addressed the intersection of scholarly communication and bibliometrics with a journal special issue and an edited book (Borgman, 1990; Borgman & Paisley, 1989), and she recently examined interim developments (Borgman, 2000a, 2000c). This review covers the decade (1990-2000) since the comprehensive 1990 volume, citing earlier works only when necessary to explain the foundation for recent developments.

Abstract

By "recommending'' Furner refers to collaborative filtering where multiple user rankings of items are used to create a single new ranking for a user, or to a system itself generating rankings of items for its users. This would include document retrieval systems as a subset recommending systems in the second instance, but in the first would make document retrieval system and recommending system synonyms. Information seeking actions are classified either as evaluative (determining the worth of an item), recommending (expressing perceived worth), or informative (examining the content of an item). The task of the information retrieval system is to be to predict the particular ordering that the user would specify in a given context, given complete knowledge of the collection. Citations may be considered as the result of evaluative and recommending decisions by the author, and assigned index terms may be considered as the same sort of decisions by the indexer. The selection of relevant documents by a searcher from a list also involves evaluative and recommending decisions. This suggests that searchers should have the opportunity to bring multiple ranking techniques to bear.

Abstract

For the purposes of this article, the indexing of information is interpreted as the pre-processing of information in order to enable its retrieval. The definition thus spans a dimension extending from classification-based approaches (pre-co-ordinate) to keyword searching (post-co-ordinate). In the first section we clarify our use of terminology, by briefly describing a framework for modelling IR systems in terms of sets of objects, relationships and functions. In the following 3 sections, we discuss the application of indexing functions to document collections of 3 specific types: (1) 'conventional' text databases; (2) hypertext databases; and (3) the World Wide Web, globally distributed across the Internet

Abstract

Margaret Egan (1905-59) taught at the Graduate Library School of the University of Chicago (1946-55) and at the School of Library Science at Western Reserve University in Cleveland, Ohio (1955-59). With her colleague Jesse Shera, Egan wrote "Foundations of a Theory of Bibliography" for Library Quarterly in 1952; this article marked the first appearance of the term "social epistemology." After Egan's death, Shera has often been credited for the idea of social epistemology. However, there is ample evidence to show that it was Egan who originated the concept-one that is commonly viewed as fundamental to the theoretical foundations of library and information science.
