Abstract

Mining evolution of topic from papers plays an important role in learning about the trend and monitoring the hot topic of research. The paper proposes a model based on Latent Dirichlet Allocation (LDA) for the purpose of mining evolution of topic. Firstly, we deal with the collection of all the papers using LDA to find out topics and their key words, and get probability distribution of document - topic on different time windows so that we can figure out the trend of topic intensity. Secondly, we apply LDA in papers on every single time window to get probability distribution of topic - word, through which we can compute similarity of topics from different time windows, and the words probability of similar topics can help us figure out trend of topic content.
