Abstract : |
This work describes a method of achieving rapid, reliable parsing of natural text through the application of three techniques: (1) resolving small questions sequentially, (2) repairing errors directly, instead of searching through a non-deterministic space, and (3) recognizing major constituents before analyzing the details of their internal structure. The resulting parser, which I call CASS, is fast and accurate. It parses a million words in 5-6 hours; that is as fast as the fastest parsers reported in the literature. Its accuracy at recognizing chunks (mid-level constituents) and at identifying subjects and predicates is 95 % or better., |
