| Outline of Final Research Achievements |
We aimed to build a language-independent typology of paraphrases through collecting and analyzing a wide variety of paraphrase examples. We collected the examples in three ways: (i) extracting those illustrated in the books and articles in the related research fields, including linguistics, natural language processing, and language pedagogy, (ii) manually analyzing existing dataset created for benchmarking the systems for recognizing textual entailment, and (iii) incrementally pre-editing sentences so that they can be translated at a higher quality by a machine translation system. We also made an attempt to find a set of descriptive features toward explicit definition of each type of paraphrases. In addition to the features proposed in previous work, i.e., the surface-level scope of paraphrases and linguistic features associated with the paraphrases, the connotational differences that paraphrases incur and contextual elements that could be affected by paraphrasing, were examined.
