SYSTEM AND METHOD FOR CREATING THREE DIMENSIONAL CLUSTERING USING HIERARCHY TERMS

摘要

PURPOSE: A system and method for creating a three dimensional clustering are provided to link a word to a document horizontally and to classify a word and a document based on a directory by grafting the hierarchy terms concept in a clustering method based on the existing similarity. CONSTITUTION: A word extracting device(101) extracts actual contents of an HTML document using an HTML DTD(Document type definition), and extracts an actual word out of filtered contents using an HTML filter and a dictionary(104), and creates an index file(107) by embodying a weight value by words. A cluster creating device(102) extracts a word having a value more than the critical weight value out of words of the corresponding document, and creates a word group(cluster) based on the extracted each word, and compares the word group(cluster) with the existing word group(cluster dictionary:105) based on the corresponding word, and creates new word group(cluster dictionary:105) based on the corresponding word. A 3-D cluster processor(103) checks whether a query language of a user exists in a classification dictionary(106). If a query language of a user does not exist in a classification dictionary, a document value is outputted using a cluster corresponded to the query language and the index file(107) in the cluster dictionary(105). If a query language of a user exists in a classification dictionary, the upper and lower linking word in the classification dictionary(106), a query language and a cluster with respect to the upper and lower linking word in the cluster dictionary(105) based on the upper and lower linking word are searched, and a document value is outputted using the cluster dictionary(105).
