Text is text mining preprocessing crucial step process, which directly affects the late job classification, clustering, association rules, such as the effect of the more conventional operations text word, to stop words, word frequency analysis, text feature extraction is also text preprocessing the core content.
Text classification is preprocessed data, the process of selecting classifier training, evaluation and feedback of results. In this paper, a common classification algorithm TF-IDF classification, NaiveBayes classification, Knn classification, decision tree classification, neural network classifiers and support vector classification. Classification does not exist merits of each set of data has its appropriate classifier, so when training classification model, you need to try different classifiers and different parameters in order to achieve the optimization model.
