Method and system for automatic update of knowledge base for online encyclopedia

Abstract

The invention provides a method for automatically updating a knowledge base oriented to online encyclopedia. The method comprises the following steps: monitoring knowledge corpus sources of the knowledge base in real time, and acquiring newly-increased knowledge corpus and knowledge corpus with changed contents according to the knowledge corpus updating time and content changes of the knowledge corpus; recognizing knowledge changes by virtue of the acquired knowledge corpus and updating the knowledge base on the basis of the recognized knowledge changes. According to the method, updated knowledge is sensed in real time, the position of the updated knowledge in the knowledge base is automatically judged, and the updated knowledge is automatically merged and added into the knowledge base, so that the hysteretic nature of the knowledge base can be avoided, and the requirement of a user on timeliness of the knowledge base can be met.

Description

technical field [0001] The invention relates to a network knowledge base, in particular to a method and system for automatically updating the network knowledge base. Background technique [0002] A knowledge base usually includes a collection of concepts, instances and relationships, which is a structured, comprehensive and organized knowledge cluster, and a collection of interrelated knowledge that is organized, managed and used in a certain knowledge representation. This knowledge includes domain-related theoretical knowledge, factual data, and heuristic knowledge obtained from expert experience, such as definitions, theorems, algorithms, and common sense knowledge related to a certain domain. In the field of knowledge engineering, the elements of knowledge description generally include four elements: concept, instance, relationship and attribute. [0003] In recent years, the construction of knowledge bases has become a hot spot in domestic and foreign industrial develop...

AI Technical Summary

Problems solved by technology

This method has the following limitations: (1) It is difficult to write complete rules to represent the addition, deletion, modification, etc. of knowledge; (2) It is difficult to meet the needs of users for real-time updates

In terms of automatic perception of updated data, there is a lack of effective methods that can automatically identify changes in knowledge and an update mechanism that can dynamically respond to these changes
