Survey of Text Classification Technique and Compare Classifier

Huge amount data on the internet are in unstructured texts can‟t simply be used for further processing by computer , therefore specific processing method and algorithm require to extract useful pattern. Text mining is process to extract information from the unstructured data. Text classification is task of automatically sorting set of document into categories from predefined set. A major difficulty of text classification is high dimensionality of feature space. Feature selection method used for dimension reduction. This paper describe about text classification process, compare various classifier and also discuss feature selection method for solving problem of high dimensional data and application of text classification.
