The Effect of Question Analysis and Searching Strategy on Performance of Retrieval Systems: Selected Results from an Experimental Study.
Saracevic, Tefko – 1968
This experiment used five index languages to form nine different index files to the same collection of documents. Each index term, in each language, was treated in two ways: as an independent English term, and as a coded entry in a faceted-type thesaurus which specified relationships between terms. The performance effect of the thesaurus was then…

Individual Differences in Organizing, Searching and Retrieving Information.
Saracevic, Tefko – Proceedings of the ASIS Annual Meeting, 1991
Synthesizes major findings from research on the magnitude of individual differences in information retrieval (IR) tasks and suggests implications for practice and design of IR systems and interfaces. Topics discussed include indexing consistency, relevance judgments, selection of subject headings, selection of search terms, and search retrievals.…

An Inquiry into Testing of Information Retrieval Systems. Comparative Systems Laboratory Final Technical Report, Part II: Analysis of Results.
Saracevic, Tefko – 1968
The Comparative Systems Laboratory (CSL) proposed to deal with the problems of testing retrieval systems by examining a number of processes involved in such systems, with particular attention to the human factor. It is hoped that the results of the project will be useful in refining methodologies for experimentation with information retrieval (IR)…
