It is important for future NLP systems to formulate the semantic equivalence (and more generally, the semantic similarity) of natural language expressions. In particular, paraphrasing, full text information retrieval, example-based MT and document compression technology require the effective equivalence criterion for linguistic expressions. In this paper, first, we discuss the meaning of Japane...

The paper addressed the question how the paraphrasing of synonyms can be linked with a fine-gained ontology based data representation. Our challenge is to identify for a set of synonyms (including terms and multiword expressions) the best lexical paraphrases suitable for given contexts. Our hypothesis is that: i. the minimal context in which the paraphrasing can be validated is different for di...

Some particular classes of lexical paraphrases such as verb alteration and compound noun decomposition can be handled by a handful of general rules and lexical semantic knowledge. In this paper, we attempt to capture the regularity underlying these classes of paraphrases, focusing on the paraphrasing of Japanese light-verb constructions (LVCs). We propose a paraphrasing model for LVCs that is b...
