Abstract:
Provided are a method and an apparatus for predicting a preference rating for content, and a method and an apparatus for selecting sample content in order to predict a preference rating for the content. In the method of predicting a preference rating for the content, a list of users having similar preferences to a target user is extracted from content usage information collected with respect to the same content, and the target user's preference rating for the content is predicted by applying preference rating information of the users with similar preferences to a machine learning algorithm.
Abstract:
The UV-curable aqueous coating composition is characterized by using a UV-curable aqueous emulsion obtained by urethane reaction with a mixture including a poly-carbonate polyol or polyester polyol; an isocyanate compound; a urethane-reactive carboxylic acid; a UV-curable acrylic oligomer having 2 to 9 functional acrylate groups; a UV-curable acrylic monomer; and a urethane-reactive acrylate without an organic solvent. The aqueous composition provides good environmental acceptability and satisfactory film properties comparable to those of the prior oily UV-curable coating composition and, therefore, it is useful for coating various plastics.
Abstract:
A system and method is capable e of connecting devices including receiving from a first device a request to select a plurality of second devices according to predetermined conditions required by the first device. The system also can generate a virtual device channel for connecting the plurality of second devices to the first device.
Abstract:
