[Results] The experimental results show that the F value of this method is 75%, which is about 10% higher than that of the topic model. This proves the feasibility of the …
WebSep 8, 2024 · Biterm topic model is a generative probabilistic model, which assumes that the latent topics over the whole text corpus can be learnt by modeling the generation of biterms in the corpus [5, 35] directly. Here, a biterm is defined as an unordered word-pair co-occurring in a text and the frequency of the biterm is the co-occurring times of the ... WebJun 25, 2024 · Biterm topic model.
