Abstract :
In this paper we investigate possibility of using phrases of flexible length in classification of textual documents as an extension to classic bag of words document representation where documents are represented using single words as index terms. The investigation is conducted on collection of articles from Vecernji list. It is shown that usage of flexible length phrases improves precision of automatic document classification and there are indications that such approach could be used for genre classification
