- 摘要:
- 针对当前中文开放领域多元实体关系抽取研究较少的情况，借鉴国外已有的研究成果，结合中文自身的特点，提出了中文领域多元实体关系抽取的方法。该方法以句法分析结果的根节点作为入口，迭代地获取所有谓语的主语、宾语及其定语成分，再利用句法分析结果对这些成分进行完善，最终获取句子中的多个实体之间的语义关系。该方法被应用在不同的领域并进行了对比分析，实验结果表明：其具有一定的参考价值。另外，对实验数据进行了详细的分析，归纳了错误的主要情形，为今后的研究工作指明了方向。
- 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.
