The Extraction of Chinese Temporal Expressions Based on LEX

Abstract:

Temporal Expressions are important structures in natural language. Temporal information is useful in many NLP applications, such as information extraction, question answering and summarization. In this paper, we present an approach for extracting temporal expressions from Chinese texts. Using LEX parser, defining grammar rules of temporal expressions as LEX source program through the cooperation of LEX and C compiler, get the temporal expressions from unprocessed Chinese corpus. Our experiments demonstrate that on the TempEval 2010 Chinese corpus this approach is valid with the F1-measure values of 93.97%.
