In this paper, we propose a novel way for modeling topics in short texts, referred as biterm topic model (BTM).

Web1. feb 2024 · We propose a Dirichlet process biterm-based mixture model (DP-BMM) for short text stream clustering, which can alleviate the word sparsity problem in short contexts by explicitly modeling the word-pair (i.e., biterm) co-occurrence pattern at document-level. Moreover, DP-BMM can handle the online topic drift problem by exploiting the Dirichlet ... Web13. sep 2024 · A main technique in this analysis is using topic modeling algorithms. However, app reviews are short texts and it is challenging to unveil their latent topics over time. Conventional topic models suffer from the sparsity of word co-occurrence patterns while inferring topics for short texts. eagles band shirts for sale
