摘要
A dependency constraint and knowledge-based adjective meaning disambiguation method and apparatus, the method comprising: performing a dependency syntactic analysis on large-scale corpora, collecting the obtained dependency tuples and counting the absolute frequencies thereof, and creating a dependency knowledge library; performing a dependency syntactic analysis on sentences in which an ambiguous adjective is present, and extracting four dependency tuples meeting a set condition to be a dependency constraint set of the ambiguous adjective; according to a semantic dictionary, sequentially extracting, for respective meanings of the ambiguous adjective, a synonym set, a near-synonym set and an antonym set to be meaning representative word sets for corresponding meanings; according to the dependency knowledge library and the meaning representative word sets, sequentially calculating the posterior probability of each meaning of the ambiguous adjective in the dependency constraint set; and selecting an accurate meaning of the ambiguous adjective according to the posterior probability. By utilizing the method and the apparatus, the effect of a dependency syntactic analysis can be brought into full play and the meaning of an ambiguous adjective can be determined more accurately and effectively.
