WebFeb 16, 2024 · The Biterm Topic Model (BTM) is a word co-occurrence based topic model that learns topics by modeling word-word co-occurrences patterns (e.g., biterms) A biterm consists of two words co-occurring in the same context, for example, in the same short text window. BTM models the biterm occurrences in a corpus (unlike LDA models which … 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 ...
