| Research Abstract |
As the evaluation framework for text quality, we developed a statistical method that evaluates local coherence of a text. We made improvements to the entity grid local coherence model for Japanese text, and investigated the effectiveness of taking into account cohesive devices, such as conjunction, explicit reference relation, lexical cohesion, and refining syntactic roles for a topic marker in Japanese. As the evaluation framework for text content, we explored the use of paraphrases for the refinement of traditional automatic methods for summary evaluation.
