Abstract:
Based on the introduction of the features of time series and labels of the document into latent Dirichlet allocation (LDA) model, an online labeled incremental topic model was presented. Firstly, online labeled incremental topic model realizes the predicate of multilabels on the basis of the optimized label and topic mapping relation and improves the clustering results. Secondly, the online labeled incremental topic model achieves the reasonable correlation of text streams with the help of dynamic dictionary and the optimization calculation of hyperparameter. The experimental results suggest online labeled incremental topic model can improve the decision accuracy of multilabels, optimizing the generalization ability and operating efficiency.
Key words: information processing, latent Dirichlet allocation (LDA) model, natural language analysis, topic model
