To improve the extraction of attribute information related to open domain events, a method using Semantic Dependency Parsing (SDP) and a rule model is proposed. First, a small number of items are extracted from the corpus, and the template library corresponding to the attribute information is summarized. SDP is then used to process the entire corpus, identify unrecognized attribute information templates, and add them to the template library. Finally, the error-driven modification method is used
