This paper introduces a method for supporting users to select the final object(s) from the results of search/recommendation. In order to realize the purpose, our method provides the user with similes that would make the user understand the characteristic features of a pair of objects easily and quickly. In order to search suitable similes, we introduced the difference feature vector for a pair of objects. The difference feature vector emphasizes the differences of the objects in the pair and downplays the common features, because objects in a search/recommendation result set have the common features that matched the search/recommendation conditions and the common features are useless for further selection. The effectiveness of the proposed method is evaluated based on the experimental user studies and it is shown that our method can search more adequate simile pairs for the given pair of objects than the baseline method based on the simple feature vectors.
