中文摘要: 金矿实体关系的智能识别是提高金矿文献分析挖掘和知识提取的重要方法和途径。此次研究针对目前金矿实体关系抽取涉及到的核心问题,如金矿实体关系复杂、人工标注信息少等特点,提出了基于BERT(Bidirectional Encoder Representations from Transformer)的远程监督关系抽取模型。并通过金矿地质数据编码、金矿分类和金矿地质实体过滤等模块的优化改进,提高了金矿地质实体关系抽取的准确率。最后通过对金矿文献数据的实体关系抽取实验,验证了该方法的有效性。

Abstract:Intelligent identification of entity relation is an important method and approach to improve literature mining and analysis, and knowledge extraction of gold mine. This study focuses on the core issues affecting current entity relation extraction of gold mine such as complex entity relation and less manual annotation information, and proposes a BERT (Bidirectional Encoder Representations from Transformer) remotely supervised relation extraction model. The accuracy of relation extraction is increased by optimizing and improving the modules related to geological data coding, geological classification and geological entity filtering. And the effectiveness of the model is verified by the entity relation extraction experiment of 290489 pieces of gold ore documents.
