PROBLEM TO BE SOLVED: To dramatically increase the number of keywords which can be applied to a document.SOLUTION: A parameter calculation unit 11 calculates a model parameter for each keyword by using a plurality of documents to which a keyword is applied. A graph construction unit 13 calculates the degree of relation between model parameters and, by using the model parameter as each node, constructs a graph in which a link is established between nodes present close to each other on the basis of the degree of relation between the model parameters. A score calculation unit 22 calculates a score of an input document by using the model parameter. A graph scan unit 23 retrieves a graph on the basis of the score and identifies a keyword corresponding to a node which is the closest to the input document. |
