The propensity of Web information purchasers is changing from cost effectiveness that emphasizes price with performance to cost satisfaction that emphasizes purchaser's psychological satisfaction. One of the methods to improve user's cost satisfaction in recommending multimedia contents is to use mood inherent in multimedia contents.

From the analysis, it is shown that the AV values of multimedia contents with a mood tag and its synonyms reside in the area of the mood tag in the Thayor model.
