Event Extraction

Event extraction is an important subtask in natural language processing, aiming to identify events and their scopes described in the text. This task achieves a structured understanding of text content by annotating and extracting specific types of event information, such as time, location, and participants. Event extraction not only facilitates information retrieval and knowledge graph construction but also enhances the accuracy and efficiency of text analysis, finding wide application in areas like public opinion monitoring, intelligent question answering, and automatic summarization.
