This paper presents SPQR (Selectional Pat- tern Queries and Responses), a module of the PUNDIT text-processing system designed to facili- tate the acquisition of domain-specific semantic information, and to improve the accuracy and efficiency of the parser. SPQR operates by interactively and incrementally collecting informa- tion about the semantic acceptability of certain lexical co-occurrence patterns (e.g. , subject-verb- object) found in partially constructed parses. The module has proved to be a valuable tool for port- ing PUNDIT to new domains and acquiring essen- tial semantic information about the domains. Preliminary results also indicate that SPQR causes a threefold reduction in the number of parses found, and about a 40~ reduction in total parsing time.
