- Abstract:
-
In view of the scant research conducted regarding n-ary entity relation extraction in the Chinese open domain, in this paper, we propose a method for performing n-ary entity relation extraction in the Chinese domain based on existing research conducted abroad and Chinese characteristics. Starting with the root node of syntactic analysis, we obtain the subject, object, and attributive components of all the predicates. Then, we use the syntactic analysis result to perfect these elements and, finally, obtain the semantic relations of the n-ary entity. For comparative analysis, we applied the proposed method to different domains. The experimental results demonstrate its reference value. In addition, we analyzed the experimental data in detail and have summarized the main errors, which indicate the direction for future research.
