Knowledge map-based Chinese tourism domain knowledge service platform construction method

Abstract

The invention discloses a knowledge map-based Chinese tourism domain knowledge service platform construction method. The method comprises the steps of obtaining structured tourism knowledge from an existing Chinese encyclopedia knowledge base, fusing the knowledge and crawling tourism website page data; performing knowledge completion on the Infobox attributes of the entity through a self-definedattribute matching rule; using a Stanford ontology modeling tool Protege to construct a tourism domain ontology, and combining D2RQ with the constructed tourism domain ontology to convert data into anRDF triple format to obtain a tourism domain knowledge graph and a Neo4j graph database storage task of a tourism knowledge base; wherein the knowledge fusion task comprises the steps of calculatingsemantic similarity between entities by using an improved deep learning knowledge representation model BERT to complete entity alignment, performing attribute fusion based on a principle and a statistical method, and performing a triple fusion subtask by adopting a majority voting algorithm. According to the invention, tourists can obtain one-stop comprehensive services conveniently.

Description

technical field [0001] The invention belongs to the field of computer information processing, and specifically relates to a method for constructing a knowledge service platform in the field of Chinese tourism based on a knowledge map. The method integrates cognitive computing, knowledge representation and reasoning, information retrieval and extraction, natural language processing and semantic web, Various disciplines such as data mining and machine learning, by adding semantics (knowledge) to the massive tourism data on the Internet, make the data generate wisdom, complete the transformation process from data to information to knowledge, and finally to the intelligent application platform, thereby improving the travel of users Experience and realize the goals from information service to knowledge service and dissemination of tourism culture. Background technique [0002] The knowledge map describes the concepts, entities and their relationships in the objective world in a s...

Problems solved by technology

[0005] my country's tourism informatization construction has a history of more than 30 years, but there is still a lack of Chinese knowledge maps specifically for tourism, which seriously hinders the development and inheritance of my country's tourism culture

Moreover, the existing Chinese domain knowledge graphs have different data models for different fields, and the application requirements are also different. There is no set of general standards and norms to guide the construction and other issues.
