SYSTEM FOR ANALYZING DOCUMENTS

摘要

PURPOSE: A system for analyzing documents is provided to analyze patent documents by providing a user with grouping results of the patent documents through UIs(User Interfaces). CONSTITUTION: A database(130) stores patent documents, and a document classification module(150) reads out the indirect quotation relation between patent documents. The document classification module classifies the patent documents through the read indirect quotation relation. A document evaluation module(140) evaluates the patent document through the characteristic information of the patent documents. A UI(User Interface) output unit(112) provides the evaluation information on the patent document to the user.
