ONTOLOGY GENERATION DEVICE FOR SEQUENCE DIAGRAM, AND ITS PROGRAM AND METHOD

摘要

PROBLEM TO BE SOLVED: To mechanically generate task ontology from a sequence diagram. SOLUTION: An information extraction part 4 extracts information related to an actor/object, a message and order of the message from a file of the sequence diagram of an XMI (XML Metadata Interchange) format on the basis of tag information. A task activity determination part 5 determines task activity from the extracted information related to the message by morpheme analysis. An is-achieved-by structure determination part 6 determines an is-achieved-by structure from relation between the extracted order of the message and actor/object. A task context role determination part 7 determines a task context role that is input/output of each the task activity by use of a task activity dictionary 3 described with a format for the task context role corresponding to the task activity.
