<P>PROBLEM TO BE SOLVED: To provide an information output device capable of adjusting influence which each context of a user exerts on a recommendation result, for each context. <P>SOLUTION: An information output device comprises; a mode value score calculation means calculating a mode value score which is proportional to a value obtained by increasing/decreasing a probability of a set including each value (a current value) of a plurality of contexts inputted from a user terminal among sets including mode values of event information stored by an event information storage means according to a size of an initial value of an adjustment parameter corresponding to the contexts, for each of a plurality of values (mode values) which each user mode can take; a mode value score change means changing each mode value score by increasing/decreasing the adjustment parameter corresponding to the contexts based on received instruction information including information for specifying one of contexts and information about increasing/decreasing; and an information output means selecting contents having mode values of a number proportional to the mode value score of the each mode value to output them. <P>COPYRIGHT: (C)2012,JPO&INPIT |
