Topic segmentation plays an important role for discourse analysis and document understanding. Previous work mainly focus on unsupervised method for topic segmentation. In this paper, we propose to use bidirectional long short-term memory (BLSTM) model, along with convolutional neural network (CNN) for learning paragraph representation. Besides, we present a novel algorithm based on frequent subsequence mining to automatically discover high-quality cue phrases from documents. Experiments show that our proposed model is able to achieve much better performance than strong baselines, and our mined cue phrases are reasonable and effective. Also, this is the first work that investigates the task of topic segmentation for web documents.
