Using Wikipedia Knowledge To Improve Text Classification

Text classification has been extensively used to help users with the discovery of useful info from the Internet. To beat this drawback, earlier work tried to enrich text illustration via guide intervention or computerized document enlargement. The achieved enchancment is unfortunately very restricted, due to the poor coverage functionality of the dictionary, and to the ineffectiveness of time period enlargement. However, traditional classification methods are based on the “Bag of Words” (BOW) illustration, which solely accounts for time period frequency in the documents, and ignores vital semantic relationships between key phrases. In this paper, we mechanically assemble a thesaurus of concepts from Wikipedia. We then introduce an unified framework to develop the BOW illustration with semantic relations (synonymy, hyponymy, and associative relations), and reveal its efficacy in enhancing earlier approaches for textual content classification. Experimental outcomes on several information units show that the proposed method, integrated with the thesaurus constructed from Wikipedia, can achieve significant enhancements with respect to the baseline algorithm.
