A Research On Baidupedia-based Recessive Semantic Knowledge Mining

In the era of the knowledge economy, more and more rapid spread of knowledge associated withthe development of information technology to human and for human use. To keep competitive advantagein the complicated and changeable environment, human beings must speed up the pace of their knowledge.Through the study of knowledge, it is not difficult to find that our knowledge is divided into explicitknowledge and tacit knowledge, explicit knowledge we can pass everyday self-study,but tacit knowledgebecause of its characteristics of the hidden and difficult to imitate or replicate, it need we learned in themutual communication. To promote the transformation and innovation of knowledge, it is not enough onlyrelying on explicit knowledge between the deduction, because more valuable knowledge is containedwithin the tacit knowledge, we need to through full of data mining in the larger capacity of the databasecan be obtained. Therefore, how to in the era of knowledge economy and help people to obtain neededresources, mining valuable tacit knowledge becomes the focus of scholars attention. Baidu encyclopedia,is the biggest encyclopedia in China and the most valuable research corpus, with the continuousdevelopment of science into new knowledge constantly, as a knowledge base, constantly updated toprovide platform for human tacit knowledge mining, relative to other encyclopedia has incomparableadvantages. But at the moment, most people tend to be based on wikipedia platform knowledge miningresearch, and study baidu encyclopedia tool knowledge mining is relatively small. How to use baiduencyclopedia of human accurately the main resources of mining, make people quickly and efficiently findthemselves need knowledge, fully excavating implicit valuable tacit knowledge, improve the utilizationrate of information has become a hot research scholars.This paper first summarizes the connotation of tacit knowledge and data mining, points out thatthe definition of tacit knowledge and irreplaceable importance as well as the connotation of the datamining; Then in view of the recessive knowledge be innovated some obstacles that may occur in theprocess of the conclusions, then put forward the relative solutions, and on the basis of introducing the basicprocess of data mining and classification, on the basis of briefly explains several commonly used datamining techniques, and on the basis of the existing data mining technology, puts forward the tacitknowledge mining method based on the case, tacit knowledge mining method based on web, tacitknowledge mining method based on Microsoft three algorithms, and tacit knowledge mining method based on other algorithms of four kinds of recessive knowledge mining method; Finally a brief comparativeanalysis to the baidu encyclopedia encyclopedia advantages relative to the other, and based on baiduencyclopedia of this platform to put forward the corresponding semantic knowledge mining knowledgemining and semantic correlation research, on this basis, put forward by extracting recessive semanticdictionary and semantically related words to establish semantic assumption, baidu encyclopedia systemwas proposed based on wikipedia encyclopedia of tacit knowledge mining research train of thought.Paper on the basis of the relevant basic theories, make full use of existing data miningtechnology tacit knowledge mining method is put forward, and on the basis of the recessive knowledgemining technology is put forward based on baidu encyclopedia of tacit knowledge mining methods andalgorithms, and finally puts forward the research train of thought on the basis of baidu encyclopedia oftacit knowledge mining, effectively improve the speed and accuracy of people acquire knowledge, toeffectively mining valuable tacit knowledge research provides the theoretical basis, and for the laterscholars engaged in the related research on the basis of baidu encyclopedia knowledge mining,providesreference for future related research.
