| Abstract(in English) | In traditional methods for text classification, words are used as a set of features for a document However there are many string-based approaches In the string-based approaches, the number of all substrings of documents would be extremely large and we don't know which substring is important for text classification. Previous research reports that using conditional probabilities based on mutual information for extracting features is effective We reports extracting features with adaptation and that the method is more useful for text classification |
