Keywords can be used as attributes for mining rules or as a basis for measuring the similarity of new (unclassified) documents with existing (classified) ones. The focus is on the problem of extracting keywords from document collection in order to use them as attributes for document classification. Document classification is a hot topic in machine learning. Typical approaches extract “features,” generally words, from document, and use the feature vectors as input to a machine learning scheme that learns how to classify documents. This “bag of keywords” model neglects keyword order and contextual effects.
