SLDA-TC: A Novel Text Categorization Approach Based on Supervised Topic Model[J]. Acta Electronica Sinica, 2019, 47(6): 1300-1308. DOI: 10.3969/j.issn.0372-2112.2019.06.017.
a novel text categorization model based on supervised topic model is proposed.The new parameter represents the probability distribution of topic-category is introduced.The SLDA-TC-Gibbs sampling algorithm is presented.At each iteration
a word's latent topic sampling only utilizes the other training documents having the same category with the document the word occurred
meanwhile
the theoretical proof is given.In the SLDA-TC model
the number of topics is only slightly larger than the number of categories.The experimental results demonstrate that the SLDA-TC model promotes the accuracy and speed for text classification compared with the LDA-TC and SVM algorithms.
