Li, Hang; Yamanishi, Kenji – Information Processing & Management, 2002
Proposes a new method of text classification using stochastic decision lists, ordered sequences of IF-THEN-ELSE rules. The method can be viewed as a rule-based method for text classification having advantages of readability and refinability of acquired knowledge. Advantages of rule-based methods over non-rule-based ones are empirically verified.…

Gillaspie, Deborah L. – Proceedings of the ASIS Annual Meeting, 1992
Discusses a study in progress that is analyzing retrieval failures in two full-text computer-assisted legal research (CALR) systems, LEXIS and WESTLAW. Computer searching by experts is compared with manual searching by experts, examples are given, and a taxonomy of causes of retrieval failure is discussed. (13 references) (LRW)

Cooper, David; Lynch, Michael F. – Information Processing and Management, 1984
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…

Mendelsohn, Henry N. – Database, 1984
Two subject profiles (social welfare direct practice and management) were used to search 13 social science databases in order to examine extent of online coverage of social welfare literature. Journal coverage data for 20 titles were obtained and most recent citations were retrieved to compare currency of indexing (5 references). (EJS)

Saveleva, Melinda – 1990
It is commonly believed that the quality of original cataloging on OCLC (Online Computer Library Center) and RLIN (Research Libraries Information Network) significantly differs. Past stereotypes reflected the fact that OCLC traditionally emphasized increasing the size of the database, while RLIN ascribed top priority to cataloging quality. The…
