Topical query decomposition
Francesco Bonchi, Carlos Castillo, Debora Donato, Aristides Gionis · 2008
We introduce the problem of query decomposition, where we are given a query and a document retrieval system, and we want to produce a small set of queries whose union of resulting documents corresponds approximately to that of the original query. Ideally, these queries should represent coherent, conceptually well-separated topics.
