In this paper , we use TF-IDF ( a kind of augmented DF ) as a feature selection criterion , in order to ensure results are comparable with those in ( Yahyaoui , 2001 ) . TF-IDF ( term frequency-inverse document frequency ) is one of the widely used feature selection techniques in information retrieval ( Yates and Neto , 1999 ) . Specifically , it is used as a metric for measuring the importance of a word in a document within a collection , so as to improve the recall and the precision of the retrieved documents .
