词汇概念结构将动词表示为语义结构，只有有限数量的语义谓词。本文试图探讨如何运用语言认知理论来解释词汇和句法释义背后的潜在问题，如动词交替、复合词分解和词汇派生。本文提出了一个将动词的语篇转换为释义的生成模型，并以日语轻动词结构的释义为例进行了实证实验。实验结果表明，在释义生成过程中，动词的句法和语义特征对句法转换的语义约束是有效的。
Lexical Conceptual Structure (LCS) represents verbs as semantic structures with a limited number of semantic predicates. This paper attempts to exploit how LCS can be used to explain the regularities underlying lexical and syntactic paraphrases, such as verb alternation, compound word decomposition, and lexical derivation. We propose a paraphrase generation model which transforms LCSs of verbs, and then conduct an empirical experiment taking the paraphrasing of Japanese light-verb constructions as an example. Experimental results justify that syntactic and semantic properties of verbs encoded in LCS are useful to semantically constrain the syntactic transformation in paraphrase generation.
