Publication number: 20050273314Abstract: A method for processing natural language Chinese sentences can transform a Chinese sentence into a Triple representation using shallow parsing techniques. The method is concerned with parsing Chinese sentences by employing lexical and syntactical information to extract more prominent entities in a Chinese sentence, and the sentence is then transformed into a Triple representation by employing the Triple rules referring to elemental Chinese syntax—SVO (subject, verb, and object in order). The lexical and syntactical information in our method is referring a lexicon possessed of part-of-speech (POS) information and phrase-level syntax in Chinese respectively. The Triple representation consists of three elements which are agent, predicate, and patient in a sentence.Type: ApplicationFiled: June 7, 2004Publication date: December 8, 2005Applicant: SimpleAct IncorporatedInventors: Feng-Lin Chang, Yi-Chun Chen, Hua-Sen Cheng
