Automatic Rewriting of News into Easy Japanese

Supporting the production of NEWSWEB EASY

Outline

We are conducting research in support of NHK’s “NEWSWEB EASY”*, which is a news site aimed at children and foreigners learning Japanese. NEWSWEB EASY presents news in easier to understand language than in the regular news. As this entails a labor-intensive task, i.e., rewriting the regular news, we are developing a system that can automatically perform it.

Features

●Rewrite knowledge acquisition from manual rewrite examples

The system statistically learns rewrite knowledge from original news scripts and their manual rewrites and uses the knowledge when converting news into easier language.

●Segmenting sentences into simpler Japanese

The system analyses the syntactic structure of the original sentence to turn long and complex strings into shorter, comprehensible ones.

Future plans

We will continue to improve the quality of automatically rewritten sentences so that it can be used as a production support system of NEWSWEB EASY.
