METHOD OF GENERATING LANGUAGE FEATURE EXTRACTION MODEL, INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND PROGRAM

A method of generating a language feature extraction model that causes a computer to extract a feature from a text related to an image, includes that a system performs machine learning using training data including a first image, first position information related to a region of interest in the first image, and a first text that describes the region of interest to input the first text into a first model, which is the language feature extraction model, to cause the first model to output a first feature amount, input the first image and the first feature amount into a second model to cause the second model to estimate the region of interest, and train the first model and the second model such that an estimated region of interest output from the second model matches the region of interest of a correct answer indicated by the first position information.
