Classification of Text Document points towards associating one or more predefined categories based on the likelihood expressed by the training set of labeled documents. Many machine learning algorithms plays an important role in training the system with predefined categories. The importance of Machine learning approach has felt because of which the study has been taken up for text document clas...

Practical text classification system should be able to utilize information from both expensive labelled documents and large volumes of cheap unlabelled documents. It should also easily deal with newly input samples. In this paper, we propose a random walks method for text classification, in which the classification problem is formulated as solving the absorption probabilities of Markov random w...
