SiNER: A Large Dataset for Sindhi Named Entity Recognition (2020.lrec-1)
Copied to clipboard
| Challenge: | Named entity recognition is an essential lower-level task in natural language processing (NLP). |
| Approach: | They propose to develop a named entity recognition dataset for low-resourced Sindhi language with quality baselines. |
| Outcome: | The proposed dataset is likely to be a significant resource for statistical Sindhi language processing. |
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. |
