Encoding Conversation Context for Neural Keyphrase Extraction from Microblog Posts (N18-1)
Copied to clipboard
| Challenge: | Existing keyphrase extraction methods suffer from data sparsity problem when conducted on short and informal texts. |
| Approach: | They propose a neural keyphrase extraction framework for microblog posts that takes conversation context into account and uses four types of neural encoders to represent conversation context. |
| Outcome: | The proposed framework outperforms state-of-the-art keyphrase extraction methods on Twitter and Weibo datasets. |
Improving Unsupervised Keyphrase Extraction using Background Knowledge (L18-1)
Copied to clipboard
| Challenge: | Existing methods of keyphrase extraction are supervised and unsupervised . Topical PageRank uses topical information to extract the top topics of a document . |
| Approach: | They propose an unsupervised method for keyphrase extraction based on Wikipedia . they construct a semantic graph and transform the extraction problem into an optimization problem . |
| Outcome: | The proposed method improves over other state-of-the-art models by more than 2% in F1-score. |
