Chinese Automatic Entity Relation Extraction

Entity Relation Extraction is one of the important research fields in Information Extraction.This paper presents a novel method through dividing the entity relations into two categories: embedding relations and non-embedding relations.After some simple experiments,we discover that some syntactic features have explicitly different effects on the identification of the two kinds of relations.So two different set of syntactic features are suggested to extract the two categories.Experiments show that the new method achieves an improved performance on the ACE2007 Corpus for Chinese entity relation extraction task.
