Báo cáo khoa học: "Extracting Narrative Timelines as Temporal Dependency Structures" ppt

... existing temporal informa- tion extraction models formulate temporal linking as a pair-wise classification task, where each pair of events and/or times is examined and classified as having a temporal ... models (SRP and MST) we proposed two baselines. Both are based on the assumption of linear temporal structures of narratives as the temporal ordering process that was evidenced...

... seg- mentation as a comma disambiguation problem. The problem is basically one of separating commas that mark sentence boundaries (such as [2] and [5] in (1)) from those that do not (such as [1], [3] ... boundary detec- tion task that disambiguates commas, if successfully 631 solved, simplifies downstream tasks such as parsing and Machine Translation. The rest of the paper is organized...

... Structures 2.1 Dependency tree We follow the definition of dependency graph and dependency tree as given in (McDonald and Nivre, 2011). A dependency graph G for sentence s is called a dependency tree ... generating word-based dependency trees from PASs which are generated by a state-of- the-art HPSG parser. We found that dependency trees transformed from these HPSG PASs achieve...
