The DR-LINK (Document Retrieval through Linguist Knowledge) search system was created to help automate the process that research librarians use to convert information needs, as stated by users, into the information retrieval process. DR-LINK resulted from participation in the United States Government initiative called Tipster that was sponsored by the Advance Research Project Agency. DR-LINK contains several independent retrieval technologies that are blended to create a new information retrieval process; central to this new process are the concepts of psycholinguistics. The benefits of the DR-LINK search system permit natural language queries to be input by trained information specialists or novice users. For the novice, the query can be formulated as an expression of interest to the research librarian who would convert the information needs into the information retrieval process. For the experienced searcher, the process allows more time to be given to analysis of results. Searching goes beyond the traditional search term-based system, allowing for automatic term expansion and the removal of ambiguities of search terms. Consequences of events and temporal references may be part of the query. Results are presented in a ranked order presenting the most relevant items to be scanned first. (Contains 18 references.)
