Linguistic searching versus relevance ranking: Dr‐Link and Target

Limitations of traditional Boolean searching are claimed to be overcome by two alternative search systems: DR‐LINK, a linguistic search system, and TARGET, 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 effectiveness of both search systems. A controlled dataset was used to measure the results. System features are compared and discussed. Relevance overlap and search capabilities are evaluated and results are presented.
