In literature, many feature types and learning algorithms are proposed for document classiication. However , an extensive and systematic evaluation of the various approaches has not been done yet. In order to investigate diierent text representations for document classiication, we have developed a tool which transforms documents into feature-value(More)
In document analysis, it is common to prove the usefulness of a component by an experimental evaluation. By applying the respective algorithms to a test sample, some effectiveness measures such as recall, precision, and accuracy are computed. The goal of such an evaluation is twofold: on the one hand it shows that the absolute effectiveness of the algorithm(More)
