Abstract: Under a preliminary environment, test searches with a current algorithm and a new algorithm are performed. Based on evaluation values related to rankings of the searches calculated based on these results, a first evaluation value for the current algorithm and a second evaluation value for the new algorithm are acquired. A control is performed to present relative evaluation information of the new algorithm with respect to the current algorithm based on these first evaluation value and second evaluation value. The evaluation values related to the rankings are calculated based on relevance corresponding information. In the relevance corresponding information, a relevance score is made to correspond to a test query of a test content data item for each set of the test query and the test content data item related to this test query.

Abstract: A recipe providing system and a recipe providing method for presenting a suitable recipe that matches to a user request on specific foodstuff basis and/or specific cooking process basis. A recipe element storing unit stores a recipe element data related to recipes. The recipe elements are hierarchized according to cooking process of one recipe and each of the recipe element has link information to a finished-dish for which the recipe element is used. A recipe generating means retrieves/extracts recipe element data from the recipe element storing unit in accordance with user's recipe request, and generates a recipe. A recipe sending means sends the recipe generated by the recipe generating means to users.

Abstract: To present a moving picture processing device having a user interface very easy to use when selecting part of moving pictures from multiple moving pictures. The moving picture processing device comprises a moving picture display unit for displaying whole or part of plural stored moving pictures sequentially, an input accepting unit for accepting an input for display of moving picture, a moving picture menu compiling unit for compiling a menu of moving pictures displayed when the input accepting unit accepts the input, and a menu display unit for displaying a menu of moving pictures compiled by the moving picture menu compiling unit.
