improving fulltext precision on short queries using simple constraints
Marti A Hearst
PICO-based querying in information retrieval is merely an instance of faceted querying , which has been widely used by librarians since the introduction of automated retrieval systems ( e.g. , Meadow et al. 1989 ) . The work of Hearst ( 1996 ) demonstrates that faceted queries can be converted into simple filtering constraints to boost precision . The feasibility of automatically identifying outcome statements in secondary sources has been demonstrated by Niu and Hirst ( 2004 ) .
