Abstract
The individual keeps increasing as digital contents spread and the amount of circulation expands and accessible volume of information increasing, too. The problem of the search engine to access target contents can be divided roughly into three "Grasp of the information space", "Acquisition of useful knowledge", and "Correspondence to the information update". In the research of the image retrieval, the development of the similar retrieval technique by the distance judgment of the feature vector space is a main current because it deals with the above-mentioned each problem. However, the example of researching the search engine that values use of the image contents is few. Then, it aims to aim at the development of the technique for tying to acquisition the grasp, and to investigate the user's demand for the image contents retrieval in report. The system that used it to investigate composed of the interface where SOM was used and the intuitive operation frequency is a little. The user's being demanding from the image retrieval as a result of the investigation was able to make something concrete.
