Optimising topical query decomposition
Marcin Sydow, Francesco Bonchi, Carlos Castillo, Debora Donato · 2009
Topical query decomposition (TQD) is a paradigm recently introduced in [1], which, given a query, returns to the user a set of queries that cover the answer set of the original query. The TQD problem was studied as a variant of the set-cover problem and solved by means of a greedy algorithm.
