E-XTRACT: A Tool for Extraction, Analysis and Classification of Events from Textual Requirements

This paper presents, a domain independent tool, developed in JAVA that automates the process of extraction, analysis and classification of events from textual requirements, expressed in English as a natural language. A study on various existing event extraction tools shows that they are either domain specific or take events as actions that occur at a particular time. There is no tool which extracts events that represent system behavior and at the same time gives a result that can be reused for application in multiple domains. This tool also assists the analysts in further refining events that are identified or to add some new events relevant to application domain. Tool has been tested on several case studies from different domains and has given very promising results.
