Download full textSchipma, Peter B. – 1971
Words and word fragments from the computer-readable data bases "Chemical Abstracts Condensates" and "Biological Abstracts Previews" were analyzed in terms of length, number, and frequency of appearance to determine some parameters upon which inversion of these data bases could be predicated. Types (unique words or fragments)…

Peer reviewedFriedman, Morton P.; Greitzer, Frank L. – Journal of Educational Psychology, 1972
It is argued that the attribute-organized passage (as opposed to name-organized passage) yielded superior recall because it allowed for a hierarchically organized information retrieval scheme. (Authors/CB)

Peer reviewedBodoff, David; Enache, Daniel; Kambil, Ajit; Simon, Gary; Yukhimets, Alex – Journal of the American Society for Information Science and Technology, 2001
Addresses the query- versus document-oriented dichotomy in information retrieval. Introduces a maximum likelihood approach to utilizing feedback data that can be used to construct a concrete object function that estimates both document and query parameters in accordance with all available feedback data. (AEF)

Peer reviewedHuang, Mu-hsuan – Information Processing & Management, 2003
Uses an information processing approach to analyze the pausal behavior of end-users and identifies reasons for pausing, location of pauses, hesitation rate and pausal behavior changes over time. Confirms that searchers pause less frequently and for shorter periods as they progressed through searches over time. (Author/AEF)

Rorvig, Mark; Smith, Michael M.; Uemura, Aya – Proceedings of the ASIS Annual Meeting, 1999
Shape Recovery Analysis (SHERA), a new visual analytical technique, is applied to the N-Gram hypothesis on matched Japanese-English technical documents. Results reveal compaction in the translation of Japanese subject terms to English subject terms. The biagram approach to the Japanese data yields a remarkable similarity to the matching visualized…

Phalen, William J. – 1975
The Comprehensive Occupational Data Analysis Programs (CODAP) are designed for analyzing and retrieving occupational survey information collected by means of job inventories. Two programs that are parts of the CODAP system are described: the Ordering of Hierarchically Grouped Case Data (KPATH) program which reorders case data permitting…

Brandhorst, W. T. – 1969
An analysis of existing computerized data banks in science and technology reveals that nearly half of them involve the storage and retrieval of bibliographic data. Activity in this area has been independent and autonomous. This situation is now giving way to a new environment which involves cooperation, standards, and a rigorous rational analysis…
