摘要

Using topic models to analyze documents is a popular method in text mining. Labeled Latent Dirichlet Allocation(Labeled LDA) is one of them that is widely used to model tagged documents and to solve relevant problems, such as tagged document visualization, snippet extraction and so on. However, traditional batch inference for Labeled LDA, which runs over entire document collection, is computationally expensive and not suitable for large scale corpora and text streams. In this paper, we develop an efficient online algorithm for Labeled LDA, called online Labeled LDA(online-LLDA). It is based on particle filter, a Sequential Monte Carlo approximation technique. Our experiments show that online-LLDA significantly outperforms batch algorithm(batch- LLDA) in time, while preserving equivalent quality.
