Researchers have developed TopiCLEAR, a new framework for discovering interpretable topics from short texts by clustering document embeddings. This method integrates adaptive dimensionality reduction with iterative clustering, based on the hypothesis that human-interpretable topics correspond to low-dimensional structures in embedding spaces. Experiments on benchmark datasets and Twitter data show TopiCLEAR consistently aligns with human annotations and produces more interpretable topics than Latent Dirichlet Allocation, particularly for informal and short texts.
