An Online Semantic-enhanced Dirichlet Model for Short Text Stream Clustering (2020.acl-main)
Copied to clipboard
| Challenge: | Existing approaches to cluster short text streams exploit short text in a batch way, but determine optimal batch size is difficult since we have no priori knowledge when the topics evolve. |
| Approach: | They propose an online Semantic-enhanced Dirichlet Model for short sext stream clustering which integrates the word-occurance semantic information into a new graphical model and clusters each arriving short text automatically in an online way. |
| Outcome: | The proposed model has better performance than state-of-the-art models on synthetic and real-world data sets. |
