Abstract

The invention relates to an earthquake disaster information service method and system based on knowledge graph semantic matching. The method comprises the following steps: 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; semantically matching the answer information corresponding to the content input by the user from the earthquake disaster prevention and control knowledge graph according to the content input by the user, the earthquake disaster prevention and control corpus is firstly constructed, the pertinence is higher than that of a general corpus, and then the earthquake disaster prevention and control knowledge graph is constructed according to the earthquake disaster prevention and control corpus, semantically matching answer information corresponding to content input by a user from an earthquake disaster prevention and control knowledge graph, establishing semantic association among information through the knowledge graph on the basis of semantic matching, and establishing information matching between the user input content and an entity in the earthquake disaster prevention and control knowledge graph according to the user input content so as to obtain the answer information. The problem that the difference between the user retrieval intention and the information service provided by the system is too large is solved.

Description

Technical field [0001] The present invention relates to the field of seismic disasters, and more particularly to seismic disaster information services and systems based on knowledge spectrum spell matching. Background technique [0002] At present, with the large-scale investment in the field of earthquake disaster prevention and disaster prevention, many scholars have improved the depth and breadth of existing seismic information services in seismic defense, disaster analysis and earthquake relief. . However, there is still no shortcomings, and the existing information is not high, and the information service system cannot provide the most identical seismic refuge measures for the user's disaster scene conditions; the second is a multi-type data for seismic disaster prevention and mitigation information services. There is difficult to combat; seismic information, scenes, and disaster prevention strategies knowledge range information; user search intentions and systems provide ex...
