Crowdsourcing-based knowledge base updating method for Chinese tourism field knowledge service platform

Abstract

The invention discloses a crowdsourcing-based knowledge base updating method for a Chinese tourism domain knowledge service platform. The method comprises the following steps: constructing a tourism entity base through tourism entity names; performing entity matching with a structured Chinese encyclopedia data set to extract tourism knowledge, and constructing a tourism knowledge base; building aChinese tourism domain knowledge service platform on the basis of the tourism knowledge base, wherein the building method of the Chinese tourism domain knowledge service platform comprises a visualization method of a tourism entity knowledge graph and an entity linking method in tourism entity knowledge card display, wherein a tourism entity knowledge card comprises an Infobox attribute and an entity encyclopedia label; counting tourism entity search records of different users on the Chinese tourism domain knowledge service platform through a crowdsourcing method to regularly obtain new tourism entities; and updating the tourism knowledge base through the extracted new tourism knowledge. According to the invention, tourists can conveniently, accurately and timely obtain high-quality tourism knowledge services.

Description

technical field [0001] The invention belongs to the field of computer knowledge engineering, and specifically relates to a method for updating a knowledge base of a knowledge service platform in the field of Chinese tourism based on crowdsourcing. The method combines crowd perception, knowledge representation and reasoning, information retrieval and extraction, natural language processing, and Maps and other disciplines, through the crowdsourcing (Crowdsourcing) method in the crowd sensing technology, complete the automatic and timely update of the knowledge base, so as to provide users with tourism knowledge services more accurately and efficiently. Background technique [0002] In the context of the development of the Internet of Things, mobile Internet and big data, group sensing and group intelligence collaboration is a new "human-centered" large-scale perception and computing model developed in recent years, which has become the common concern of the current academic and...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a Chinese tourism field based on crowdsourcing in view of the problems that the above-mentioned prior art cannot effectively deal with complex, heterogeneous, dynamic, multimodal tourism data on the Internet and cannot automatically and timely update the knowledge base. The update method of the knowledge base of the knowledge service platform can obtain the task results in a fast, accurate and cost-effective manner, and make the update process of the knowledge base of the entire Chinese tourism knowledge service platform form a closed loop, so that it can be updated regularly and automatically
