TREC-3 Ad Hoc Retrieval and Routing Experiments using the WIN System.

Introduction The WIN retrieval engine is West's implementation of the inference network retrieval model [Tur90]. The inference net model ranks documents based on the combination of different evidence, e.g., text representations, such as words, phrases, or paragraphs, in a consistent probabilistic framework [TC91]. WIN is based on the same retrieval model as the INQUERY system that has been used in previous TREC competitions [BCC93, Cro93, CCB94]. The two retrieval engines have common roots but have evolved separately -- WIN has focused on the retrieval of legal materials from large (?50 gigabyte) collections in a commercial online environment that supports both Boolean and natural language retrieval [Tur94]. For TREC-3 we decided to run an essentially unmodified version of WIN to see how well a state-of-the-art commercial system compares to state-of-the-art research systems. Some modifications to WIN were required to handle the TREC topics, which bear little resem
