Investigated the relative merits of searching on titles, subject headings, abstracts, free-language terms, and combinations of these elements. The combination of titles and abstracts came the closest to 100 percent retrieval. (Author/PF)

Some of the factors that must inevitably affect the assessment of printed indexes are discussed, together with the observation of two unexpected phenomena, namely an apparent relationship between precision and searching effort, and relationships between generality and both recall and fallout.

SOLAR is an interactive Storage and On-Line Automatic Retrieval system which is operational at Washington State University. It can run continuously with virtually any mix of tasks in a general purpose computing environment. (22 references) (Author)

To assess value of abstracts in online information retrieval, this study attempts to match free-text search phrases to index terms and provides classification of documents indicating form of retrieval to be expected by searching three databases--Energyline; Management Contents; and America, History and Life. Results of a sample search are…

Reports on the design and use of a computer system designed to assist online database searchers in determining the relevance of downloaded abstracts. The system, which runs on a personal computer, includes aids for individual review of abstracts and semiautomatic determination of relevance; prospects for fully automatic use are discussed. (CDD)

Objectives of this project were to develop and test a method for automatically processing the text of abstracts for a document retrieval system. The test corpus consisted of 768 abstracts from the metallurgical section of Chemical Abstracts (CA). The system, based on a subject indexing rational, had two components: (1) a stored dictionary of words…
