Computer simulation techniques have been used successfully to evaluate loan policies at the Sears Library of Case Western Reserve University (CWRU). (Author)

Focuses on the library-user interface by relating two measures of user satisfaction, book availability and the delay associated with recalls, to the loan policy of the library. This relation is established by computer simulation techniques. (Author)

Science is described as a social system of which interactive communication is the salient feature. Implications of this view of scientific communication are considered for the planning of innovations in the system. (Author)

Presents a method for normalizing English document titles so they can be used in the online retrieval of documents: the title expressed by a noun phrase or clause is converted by parsing to a function-expression, which is transformed to a predicate-governor form and then normalized to a standard form.

Explains an experiment in text-searching retrieval for cancer questions which developed and used computer procedures (via human simulation) to select search words from medical dictionaries. This study is based on an earlier one in which search words were humanly selected, and the recall results of the two studies are compared. (Author/LRW)

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…
