This paper presents a new model integrating a recurrent neural network (RNN) and a least squares support vector machine (LS-SVM) for classification of document titles according to different predetermined categories. The new model proposed in this paper is abbreviated as neuro-SVM. Based on the neuro-SVM model, a system is implemented, using latent semantic indexing (LSI) to generate probabilistic coefficients from document titles, which are used as the input to the system. The system's performance is demonstrated with a corpus of 96956 words, from University of Denver's Penrose library catalogue and the accuracy rate of the proposed system is found to be 99.66%.
