The present invention relates to an earthquake disaster information service method and system based on semantic matching of knowledge graphs. The method includes: constructing an earthquake disaster prevention and control corpus; constructing an earthquake disaster prevention and control knowledge graph according to the earthquake disaster prevention and control corpus; In the semantic matching of the answer information corresponding to the content input by the user, this application first builds an earthquake disaster prevention corpus, which is more targeted than a general corpus, and secondly builds an earthquake disaster prevention knowledge graph based on the earthquake disaster prevention In Semantic Matching, the answer information corresponding to the content entered by the user is based on the semantic matching, and the semantic association between the information is established through the knowledge map. According to the user input content, the information matching between the user input content and the entity in the earthquake disaster knowledge map is established, so that The answer information is obtained, which solves the problem of too large difference between the user's retrieval intention and the information service provided by the system.
Description
technical field [0001] The invention relates to the technical field of earthquake disasters, in particular to an earthquake disaster information service method and system based on semantic matching of knowledge graphs. Background technique [0002] At present, with the large-scale investment in the field of earthquake disaster prevention and mitigation in the past ten years, the research of many scholars on earthquake defense, disaster analysis and earthquake relief has greatly improved the depth and breadth of the existing earthquake information services. . However, there are still deficiencies. First, the accuracy of existing information matching is not high, and the information service system cannot provide the most suitable earthquake resistance measures for users in disaster scenarios; second, the multi-type data in the process of earthquake disaster prevention and mitigation information services It is difficult to sort out the chaotic and complicated semantic associat...
