A method for constructing a knowledge service platform in the field of Chinese tourism based on knowledge graph

Abstract

A method for constructing a knowledge service platform in the field of Chinese tourism based on knowledge graphs, including obtaining structured tourism knowledge from existing Chinese encyclopedia knowledge bases, knowledge fusion, crawling tourism website page data, and matching entities with custom attribute matching rules Infobox attributes are used to complete knowledge, the Stanford ontology modeling tool Protégé is used to construct a tourism domain ontology, and the tourism ontology constructed by combining D2RQ is used to convert data into RDF triple format to obtain a tourism domain knowledge map and a Neo4j graph database storage task of a tourism knowledge base. , where knowledge fusion tasks include using the improved deep learning knowledge representation model BERT to calculate the semantic similarity between entities to complete entity alignment, attribute fusion based on principles and statistical methods, and triple fusion subtasks using majority voting algorithms. The invention is convenient for tourists to obtain one-stop comprehensive service.

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...

AI Technical Summary

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.
