![]() Mutual disambiguation is the phenomenon that the natural co-occurrence of words in queries and in documents tend to disambiguate one another. The reasons are the same as for MT: either the IR system is domain-specific, which significantly reduces the problem, or mutual disambiguation occurs. However, the general consensus in the IR community is that explicit WSD makes only marginal improvements in precision and, in some cases, degrades performance. Consider querying for banks to invest with and receiving results about the Amazon River. Our intuition is that WSD should help to improve IR systems by removing those hits to a query in the wrong sense of a word in the query. Information retrieval (IR) has seen the most work to prove explicit WSD in an application. Edmonds, in Encyclopedia of Language & Linguistics (Second Edition), 2006 Information Retrieval
