Abstract: A citation analysis examined the 28 best articles published in JASIS from 1969-1996. Best articles tend to single-authored works twice as long as the avergae article published in JASIS. They are cited and self-cited much more often than the average article. The greatest source of references made to the best articles is from JASIS itself. The top 5 best papers focus largely on information retrieval and online searching

Abstract

Empirical analysis of relevance assessments can Illuminate how different groups of readdes perceive the relationship between bibliographic records and Index terms. This experiment harvested relevance assessments from two groups: engineering students (here after "engineers") and library school students ("librarians"). These groups assessed the relevance relationships between bibliographic records and Index terms for theee literatures: engineering, psychology and education. Assessment included the indexer-selected term (the topically relevant term) as well as broader, narrower and related terms. Figures 1-8 (pages 27-35) show these terms arranged as two-dimensional term domains. Positive relevance assessments plotted across the two-dimensional term domains revealed regular patterns, here called "relevance auras." A relevance aura is a penumbra of positive relevance, emanating from bibliographic records across a term domain of broader, narrower and related index terms. This experiment attempted to compare the relevance auras produced by engineers and librarians at both a macro and micro level of aggregatinn. Relevance auras appeared in data aggregating reader groups and literatures. Micro analyses of individual records, however, showed that relevance auras were ragged or did not develop. Agreement in relevance assessment appears an the individual term basis and often independently of the formation of a relevance aura.

Abstract: The study tested the 'strategy of unlimited aliasing', an indexing method that places the alternative terms suggested by several indexers for the same information object into one index. The study aggregated the descriptors given to 21 bibliographic records from 3 databases: LISA (Library and information Science Abstracts); ISA (Information Science Abstracts); and ERIC. The subjects matched the records with descriptors in 7 different indexes that ranged from impoverished to enriched. No support for the strategy of unlimited aliasing was found

Abstract

Orthography is the linguisitc study of written language: elements of text such as letters, punctuation marks, and spelling. Information retrieval systems operate in the orthographic realm matching some text strings (i.e., index entries) from documents with other text strings (i.e., query terms) from patrons. During the early history of information retrieval, it has been convenient to assume the rationality and uniformity of orthography in order to concentrate effort building information retrieval systems. Fundamental orthographic problems have persisted into modern information retrieval systems, however, where white-space normalization and the arbitrary treatment of punctuation have exaverbated the orthographic impediment to information retrieval
