News Items Extractor

Japanese page
This is a research on the content extraction of pre-supposed items from news articles on new products. Our current system has achieved 93% accuracy of the extraction.

We have been developing an Information Extraction System NIX (News Item eXtractor). The pictures listed below are copies of the display of several versions of NIX system. The live demonstration is available on this URL by Web version NIX system (Japanese).

It is ture that the real time processing must be provided when processing wire news delivered through Internet. For the purpose we adopted a careful approach which enables us to manage it with high speed by linguistically surface processing.

We are using news articles on new products from Nihon Keizai Shinbun (Japan Economic Newspaper CD-ROM '90,'91,'92,'93,'94.

A part of this research is supported by a research grant Category B of Ministry of Education.
