PROBLEM TO BE SOLVED: To provide a learning data generation device generating learning data used when learning a scoring model on the basis of statistical model learning.;SOLUTION: The learning data generation device is provided with a plurality of documents and generates learning data that is used when learning a scoring model in a document retrieval on the basis of the statistical model learning. Word string generation means generates, for each document to be provided, one or more word strings including a word included in the document. Learning data generation means defines each of the generated word strings and a label indicating the document used when generating the word string as a query and a reference respectively and defines a set of the query and the reference as learning data.;COPYRIGHT: (C)2013,JPO&INPIT
