DR-LINK is a multi-stage document detection system (see Figure 1) being developed under the auspices of DARPA's TIPSTER Project. DR-LINK's overall goal is to simultaneously focus the flow of texts through the system by selecting a sub-set of texts on the basis of subject content and then high-lighting those sub-parts of a document which are likely spots of relevant text while enriching the semantic representation of text content by: 1) delineating each text's discourse-level structure; 2) detecting relations among concepts; 3) expanding lexical representation with semantically-related terms, and; 4) representing concepts and relations in Conceptual Graphs.
