Online knowledge map based on named entity library

Abstract

The invention discloses an online knowledge map based on a named entity library, which comprises the following steps: step 1) crawling a webpage and crawling webpage information from an entire internet to obtain an internet data set; step 2) extracting named entities; step 3) searching attribute words, traversing the internet data set in the step 1) and establishing an attribute set related to the named entities; step 4) quantifying the information and a correlation between the attribute words in the attribute set and the named entities; step 5) establishing the knowledge map and establishing a topological structure among the named entities through the correlation between the named entities and the attribute words in the attribute set to form the knowledge map; step 6) updating. The online knowledge map has the benefits that the named entities are extracted from a massive new page text message, a correlation between entity nodes and nodes is automatically established, the knowledge map is established according to knowledge nodes and a correlation among the knowledge nodes, and the updating of the knowledge map can be efficiently realized.

Description

technical field [0001] The invention relates to a method for making a knowledge map, in particular to an online knowledge map based on a named entity library. Background technique [0002] The knowledge map was first proposed by British intelligence scientist B.C. Brooks in "Basics of Information Science" that the real task of informatics is to organize, process and sort out customer knowledge, and draw a knowledge map with each knowledge unit as a node. With the development of knowledge management research, knowledge status, as an important tool of organization and management, has been extensively studied and applied in knowledge audit, knowledge organization, knowledge portal, knowledge evaluation, knowledge system and many other aspects. At present, there are mainly the following aspects in the generation technology of knowledge map at home and abroad: [0003] He Jiasheng of Diji Technology Co., Ltd. proposed a "knowledge map establishment, editing, retrieval and editin...

AI Technical Summary

Problems solved by technology

[0009] These knowledge map generation technologies need to extract specific aspects of information from a specific document set or relational database. Every time a knowledge map is constructed, the necessary information needs to be collected and mined again. Facing the rapid development of Internet information, it is difficult to achieve efficient Add new knowledge to achieve efficient knowledge map update
