LINGUISTIC SEARCHING VERSUS RELEVANCE RANKING: DR-LINK AND TARGET

摘要

Limitations of traditional Boolean searching are claimed to be overr come by two altemative search systems DR-LINK, a linguistic search system, and TARGgr, a relevance ranking system. This paper compares the system and search features of both and describes conceptual differences in system design. A series of test questions was developed to test the retrieval erfective- ness of both search systems. A controlled dataset was used to measure the results. System features are compared and discussed. Relevance overlap and search capabifities are evaiuated and results are presented
