DR-LINK is an information retrieval system, complex in design and processing, with the potential for providing significant advances in retrieval results due to the range and richness of semantic representation done by the various modules in the system. By using a full continuum of linguistic-conceptual processing, DR-LINK has the capability of producing documents which precisely match users' needs. Each of DR-LINK's six processing modules add to the conceptual enhancement of the document and query representation by means of continual semantic enrichments to the text. Rich representations are essential to meet the retrieval requirements of complex information needs and to reduce the ambiguities associated with keyword-based retrieval. To produce this enriched representation, the system uses lexical, syntactic, semantic, and discourse linguistic processing techniques for distilling from documents and topic statements all the rich layers of knowledge incorporated in their deceptively simple textual surface and for producing a textual representation which has been shaped by all these levels of linguistic processing.
