Fast Concept Mention Grouping for Concept Map-based Multi-Document Summarization (N19-1)
Copied to clipboard
| Challenge: | Concept map-based multi-document summarization is a subtask of CM-MDS that requires a pairwise comparison to improve the summary quality. |
| Approach: | They propose to use locality sensitive hashing, approximate nearest neighbor search and a fast clustering algorithm to group concepts into a single concept map. |
| Outcome: | The proposed methods exhibit linear and log-linear runtime complexity, making them much more scalable. |
