基于HNC理论的句法结构歧义消解

An HNC Approach to the Resolution of Syntactic Structural Ambiguity

歧义消解是自然语言理解和处理所面对的核心问题。基于词组和短语的消歧不能保证消歧结果的正确 ,歧义的成功消解基于对语境或上下文 (context)的正确理解。HNC理论采取的概念基元化、层次化、网络化、形式化策略以及在此基础上建立的句类和句式体系 ,为自然语言的歧义消解提供了最大的可能。基于HNC理论的歧义消解的总体原则是 ,以语句为基础 ,充分利用语句语境提供的句类知识 ,采取宏观消歧与微观消歧相结合的策略。对于经典句法歧义结构V +NP1+的 +NP2 ,本文描述了其三重性歧义性质 。

Disambiguation has always been the focus of natural language understanding and processing. Successful disambiguation relies on the correct understanding of a given context. The HNC theory is characteristic of its formalized representation of conceptual primitives, its arrangement of concepts in a hierarchical network, and its development of the sentence category (SC) and sentence format (SF) systems. All this provides the utmost possibility for resolving ambiguity in natural languages. The overall principle for HNC-based disambiguation is to take sentence as the basis for disambiguation and to integrate micro disambiguation into macro disambiguation. In the case of V+NP1+的+NP2, a triple ambiguous syntactic structure in the HNC perspective, proper rules are suggested for its disambiguation.
