逻辑语义学是用现代逻辑方法研究自然语言的句法生成及其语义组合规律的学科。哲学的理性主义和经验主义影响逻辑语义学的研究,逻辑语义学本质上奉行的是理性主义的方法。传统的逻辑语义学自20世纪70年代诞生以来,遵循理性主义方法取得了一系列成果。对经验主义方法的漠视却导致逻辑语义学面临发展的困境,其研究成果脱离自然语言的实际情况,不能满足计算机处理大规模真实文本的需求。理性主义和经验主义的兼容是方法论的创新,逻辑语义学发展的新模式——组合范畴语法CCG就是这一方法论创新的产物。
Logical semantics is a discipline that studies the syntactic formation and semantic combination rules of natural languages by using modern logic methods. Philosophical rationalism and empiricism affect the study of logical semantics, logic semantics essentially follow the rationalist approach. Since the birth of the traditional logical semantics in the 1970s, a series of achievements have been achieved following the rationalist approach. Disregard of the empirical method leads to the logic semantics facing the dilemma of development. Its research results are out of the actual conditions of natural language and can not meet the demand of computers for processing large-scale real texts. The compatibility of rationalism and empiricism is a methodological innovation, a new model of logical semantics - CCG is a product of this methodological innovation.
