英文摘要 | We present an event extraction framework to detect event mentions and extract events from the document-level financial news. Up to now, methods based on supervised learning paradigm gain the highest perfor- mance in public datasets (such as ACE 20051, KBP 20152). These methods heav- ily depend on the manually labeled train- ing data. However, in particular areas, such as financial, medical and judicial do- mains, there is no enough labeled data due to the high cost of data labeling process. Moreover, most of the current methods focus on extracting events from one sen- tence, but an event is usually expressed by multiple sentences in one document. To solve these problems, we propose a Document-level Chinese Financial Event Extraction (DCFEE) system which can au- tomatically generate a large scaled labeled data and extract events from the whole document. Experimental results demon- strate the effectiveness of it. |
