INPUT TEMPLATE PREPARATION KNOWLEDGE EXTRACTION METHOD FROM TEXT DB

摘要

PROBLEM TO BE SOLVED: To drastically reduce the load of manual template description, and to extract detail template knowledge whose extraction used to be impossible by a normal data mining method.

SOLUTION: The morpheme analysis and modification analysis of sentences in a DB are carried out, and the candidates of a typical description pattern called generalized case expression is generated. Thus, it is possible to automatically generate template candidates having proper fineness by executing the frequency analysis of words or generalized case expression in a remark field appearing in records having a discrimination field fulfilling a prescribed condition.
