Abstract: Entity relationship extraction is an important technology of knowledge graph. In this paper, we analyze the technology development status in this field from the perspective of patents. Firstly, analyze the trend of patent application in this field, the main domestic and foreign applicants, and important patents in this field, find the technical evolution routes combining the contents of non-patent technical literatures, so as to get the current technical development overview of entity relationship extraction technology.
Keywords: knowledge graph; entity relation extraction; patent analysis; intellectual property
