Summary:The invention discloses a relay protection defect text quality evaluation method based on an ontology and a knowledge graph. The method comprises the following steps: firstly, aiming at a relay protection device defect record, combining power grid defect data and a defect professional dictionary, and utilizing a traditional manual and machine automation combined method to construct a relay protection defect body and a knowledge graph; secondly, aiming at three common defect text recording problems, correspondingly providing three protection device defect recording text quality evaluation indexes, namely integrity, accuracy and redundancy; and finally, a subjective and objective combination method combining an analytic hierarchy process and an entropy weight method is adopted to realize comprehensive evaluation of the text quality. 本发明公开了一种基于本体和知识图谱的继电保护缺陷文本质量评价方法。本发明首先针对继电保护装置缺陷记录，结合电网缺陷数据及缺陷专业词典，利用传统人工和机器自动化相结合的方法，构建继电保护缺陷本体和知识图谱。其次，针对三种常见的缺陷文本记录问题，相应地提出了3项保护装置缺陷记录文本质量评价指标，即：完整性、准确性、冗余度。最后采用层次分析法和熵权法结合的主客观结合
