Abstract

Provided are a system and method of clustering documents. The system includes a document DB, a document feature writing unit storing documents, a document retrieving unit, a clustering unit, and a cluster DB. The document DB stores documents. The document feature writing unit extracts attribute information of documents stored in the document database, and writes indexes with respect to the respective documents on the basis of the attribute information. The document retrieving unit retrieves documents including a query input by a user, using the indexes. The clustering unit includes a representative vector calculator calculating feature vectors and a representative vector of the retrieved documents, and a similarity calculator calculating similarities between the documents using the feature vectors and the representative vector. The cluster database stores documents clustered by the clustering unit.

Description

technical field [0001] The present invention relates to a document clustering system and method, which can determine the similarity between documents and cluster similar documents based on the determined similarity. Background technique [0002] In recent years, document retrieval systems have been widely used, which can process a large amount of document information, extract information corresponding to a user's needs, and provide the extracted information to the user. [0003] That is, document retrieval or information retrieval refers to searching for a document or information desired by a user from a large number of documents and information. To retrieve documents or information, keyword processing is performed on natural language text, weights are assigned to each keyword, and then retrieval and ranking are performed. [0004] A document retrieval system in the prior art receives a query from a user, and outputs common results extracted by a common system to the user. ...
