Abstract

Short texts' data sparsity makes them difficult to find out their document-level word co-occurrence patterns, that's why conventional topic models like LDA experience a large performance degradation over short texts. As a derivative product of learning neuro probabilistic language model, word embedding can well express semantic similarity of word. In this paper, we propose a new model called promotion-BTM, which promotes the probability that similar words based on word embedding belong to the same topic. It also distinguishes the words of a biterm into topical word and general word, and only promotes topical words' semantically similar words. Extensive experiments on real-world datasets show that our model exceeds the baseline model BTM on all evaluations.
