The invention discloses an event extraction and processing method for case-following electronic files. The method comprises the following steps: step 1, acquiring required file data from a case-following electronic file circulation processing platform and storing the required file data into a database; 2, constructing an event trigger word dictionary, matching an electronic file event descriptionparagraph, and performing text preprocessing methods such as sentence segmentation, word segmentation and part-of-speech tagging; 3, event attribute extraction: combining dependency syntax analysis and a semantic role labeling method to obtain six event attributes including an applicant, a susceptor, a behavior, time, a place and a mode of an event; and step 4, event aggregation: aggregating the atomic events into topic events, combining similar topic events, and storing the topic events into an event database. According to the method, the problem that crime fact information is rapidly obtained by the case-following e
