An enhanced text classifier for automatic document classification

Abstract

Automatic classification has become an important research area due to the exponential growth of digital content in the modern world. Evidently, manual classification of documents is very painstaking and laborintensive task. It takes much time to organize a collection of documents according to the subject area. This research has developed a computer programme that can automatically classifying a given text document. Therefore, the user gets correct classification results just after feeding the document to the new system. For the process of classification, we use a new algorithm developed by enhancing basic form of an existing text classifier called tf-idf. The results were obtained for classification accuracy of the new text classification algorithm. They were compared with the results obtained for the basic tf-idf classifier. The research revealed that, the newly developed classifier algorithm can obtain better classification accuracy than the basic tf-idf classifier.
