The underlying principle of the DR-LINK System is that retrieval must be at the conceptual level, not the word level. That is, a successful retrieval system must retrieve on the basis of what people mean in their query, not just what they say in their query. The same is true of documents - their representation needs to capture the content at the conceptual level of expression. To accomplish this human-like goal, DR-LINK aims to represent and match documents and queries at all of the available levels of linguistic expression at which meaning is conveyed Accordingly, we have developed a modular system which processes, represents, and matches text at the lexical, syntactic, semantic, and discourse levels of language. In concert, these levels of representation permit DR-LINK to achieve a level of intelligent retrieval beyond more traditional approaches.
