Method for building conceptual knowledge map based on Wikipedia

Abstract

The invention discloses a method for building a conceptual knowledge map based on Wikipedia, which includes steps: firstly, extracting knowledge documents from a Wikipedia full-text database and classifying and storing the extracted documents; secondly, analyzing each knowledge document to obtain knowledge information and storing the knowledge information in a database; thirdly, transforming the knowledge information into corresponding conceptual knowledge nodes and category knowledge nodes on the basis of standards in a knowledge node format description library and storing the knowledge nodes in file format locally; fourthly, building an index to provide a function of knowledge information searching via key words and displaying the searching results. The conceptual knowledge map is applicable to a plurality of fields, the knowledge information can be updated along with Wikipedia, obtaining knowledge source is easy, knowledge information is comprehensive, extensible markup language is adopted to describe the knowledge node information, and accordingly, the conceptual knowledge map is high in extensibility and can be applied to multiple platforms.

Description

technical field [0001] The invention belongs to the field of knowledge management, and in particular relates to a method for constructing a conceptual knowledge map by using Wikipedia. Background technique [0002] Since the 1990s, with the rapid development of modern information technology, mankind has entered the era of knowledge economy. On the one hand, the total amount of knowledge is increasing rapidly, and knowledge resources are increasingly abundant. The value has also continued to increase. The emergence of knowledge management is to effectively organize and manage these rapidly growing massive knowledge, to exert the huge power of knowledge, and to enable it to create greater value. [0003] Knowledge management is a series of processes that transform intellectual capital into value, including knowledge acquisition, organization, transmission, sharing, dissemination, application and innovation. Its purpose is to deliver the most appropriate knowledge to the most...

Problems solved by technology

[0006] Although knowledge maps have become a research hotspot in knowledge management, traditional knowledge maps are often artificially produced for a specific purpose in a specialized field. New systems need to be re-developed, and the versatility is not strong, and because the information of knowledge sources is not easy to obtain, the development efficiency is very low. At the same time, the knowledge in these knowledge maps is static and cannot reflect the latest knowledge changes. In 2009, some researchers used data mining and natural language processing algorithms to realize the construction method of dynamic knowledge map, but the difficulty of understanding the algorithm and the complexity of improvement hindered the realization of knowledge map construction
