APPARATUS FOR PROVIDING ASPECT-BASED DOCUMENTS CLUSTERING THAT RAISES RELIABILITY AND METHOD THEREFOR

摘要

An apparatus for providing aspect-based documents clustering and a method thereof are provided to improve reliability by correcting an error of a clustering result by a feedback of a user. A document clustering part(100) extracts a keyword of documents, calculates importance of each keyword, executes a document clustering with the keyword and the importance, and corrects a result of the document clustering by using a user feedback. A keyword extracting unit(110) classifies the documents, and extracts a keyword from a classified documents. An importance calculating unit(120) calculates an importance of each keyword based on a text content of the documents. A similarity calculating unit(130) calculates a similarity between the documents. A clustering number decision unit(140) groups the documents, determines the number of document clustering, and generates a document clustering result according to the number of clustering. A post processing unit(150) corrects an error generated in the clustering result by a cooperative clustering.
