Abstract: A system and method for improving performance of unstructured text extraction. The system includes an unstructured data processing unit configured to extract time information or space information in which an event keyword and an event have been generated by performing a linguistic analysis on collected unstructured text and to generate extraction knowledge candidates by mapping the time information or space information to the event keyword and a filter unit configured to determine the validity of the extraction knowledge candidates generated by the unstructured data processing unit using spatiotemporal association structured data.
