A Disaster Event Information Extraction Method Based on Preposition’s Usages

doi:10.3969/j.issn.1006-2475.2015.07.026

Abstract

Abstract: To improve the efficiency of the event information extraction, through the recognition of preposition’s usages in text, an approach based on preposition’s usages and Conditional Random Fields(CRFs) is proposed for event information extracting, and the paper completes the coding of extraction system, in order to achieve the better extraction result. “People’s Daily” is used as experiment corpus, the approach achieves a better performance, the precision rate reaches 90.33%, increases 9.14% than the method without preposition’s usage.

Key words: information extraction； preposition&rsquo, s usages； disaster event； event element； CRFs
