句法-词义模式识别中递归结构的文法推断
Grammatical Inference for Recursive Structures in Syntactic-Semantic Pattern Recognition
-
摘要: 本文在文献[1]的基础上进一步研究递归结构的句法-词义文法的推断问题.描述体系采 取以基本递归结构为予模式形成分层文法的形式.推断策略是从样本的词义化表述入手,以 形式自相关搜索递归结构,通过模式结构分割建立模式的分层模型,从而构成主干文法和予文 法.这一推断策略具有相当普遍的意义.Abstract: Based on [1], the paper further studies the inference problems of syntactic-semantic grammar in recursive structures. The inference strategy starts from the semantic representation of pattern samples, then searches all the existing recursive structures by means of formal autocorrelation, and establishes hierarchical pattern models by structural segmentation, finally constructs the trunk grammar and all the subgrammars. Such a strategy may-be characterized by its simplicity and wide generality in practice.
