Recommendation information output system and recommendation information output method

A recommendation information output system, comprising:

• an electronic musical instrument configured to store a plurality of contents being tone data usable in the electronic musical instrument and to produce a musical sound from the tone data;
• a frequency storage means comprising a hard disk drive, storing in association, from the electronic musical instrument, a user identifier specifying a user at a time when the electronic musical instrument is used through a portable terminal, a content identifier specifying a content among the plurality of contents used at the time, and a usage frequency of the content;
• and
• a processor configured to calculate a correlation degree between usage frequencies of the plurality of contents and in association with a request user represented by a user identifier stored in the frequency storage means and usage frequencies of the plurality of contents in association with a user other than the request user stored in the frequency storage means, and to output and display information as a recommendation information to the portable terminal, wherein the recommendation information is information relating to a recommendation content specified from the plurality of contents in accordance with the correlation degree and in association with the user identifier stored in the frequency storage means,
• wherein the processor is configured to specify a user with a first content among the plurality of contents having a highest calculated correlation degree as a similar user, then calculate usage frequency differences between usage frequencies corresponding to the plurality of contents in association with the similar user and the usage frequencies corresponding to the plurality of contents in association with the request user, and output information relating to a second content among the plurality of contents having a biggest difference among the usage frequency differences as the recommendation information to the portable terminal,
• wherein the electronic musical instrument is configured to store the recommendation information as added tone data to produce the musical sound with the added tone data.

A recommendation information output method, comprising:

• providing an electronic musical instrument storing a plurality of contents being tone data usable in the electronic musical instrument to produce a musical sound from the tone data;
• a frequency obtaining step of obtaining by a processor, from the electronic musical instrument, a user identifier specifying a user at a time when the electronic musical instrument is used through a portable terminal, a content identifier specifying a content among the plurality of contents used at the time, and a usage frequency of the content;
• a frequency storage step of storing in association the usage frequency obtained in the frequency obtaining step with the user identifier and the content identifier in a frequency storage means in a hard disk drive;
• and
• calculating by the processor to calculate a correlation degree between usage frequencies of the plurality of contents in association with a request user represented by a user identifier stored in the frequency storage step and usage frequencies of the plurality of contents in association with a user other than the request user stored in the frequency storage step, and outputting and displaying information as a recommendation information to the portable terminal, wherein the recommendation information is information relating to a recommendation content specified from the plurality of contents in accordance with the correlation degree and in association with the user identifier stored in the frequency storage step,
• specifying a user with a first content among the plurality of contents having a highest calculated correlation degree as a similar user by the processor, then calculate usage frequency differences between usage frequencies corresponding to the plurality of contents in association with the similar user and the usage frequencies corresponding to the plurality of contents in association with the request user, and outputting information relating to a second content among the plurality of contents having a biggest difference among the usage frequency differences as the recommendation information to the portable terminal,
• storing the recommendation information in the electronic musical instrument as added tone data to produce the musical sound with the added tone data.
