The update of the database includes the update of the music information management database.

(Overall processing)
FIG. 23 shows an overview of overall processing in the music providing server. The entire process in the music providing server 1 includes correlation creation (step S51), recommended music registration, extraction (step S52), display, streaming, and reproduction (step S53).

  In the correlation creation, processing corresponding to each of the three processes in the above-described in-vehicle device ("search process from person", "process to search from evaluation", and "process to search from comment") is performed. “Process to search from people” includes a process of creating a correlation (hereinafter also referred to as correlation) of “preference”, “scene”, “specific group”, “attribute”, and “distance”. The correlation creation is realized by collecting data, analyzing the collected data, and judging.

(Correlation creation (search by person-preference) processing)
FIG. 24 shows an outline of processing for creating a correlation (searching for a person-preference). In the correlation creation (search by person-preference) process, the “favorite” button is selected on the “top screen for searching for a song from another user” shown in FIG. 17, and the CPU 31 of the in-vehicle device sends a message to that effect to the music providing server 1. It starts with that.

  In step S61, the CPU 15 of the music providing server collects data (hereinafter also referred to as acquisition) from each terminal device. The case of song preference will be described as an example. The CPU 15 of the song providing server acquires a reproduction history as data. The data collection timing may be periodically performed or may be performed every time the reproduction of the music ends (after listening to one music). When data (reproduction history) is acquired, the process proceeds to step S62.

  In step S62, the CPU 15 of the music providing server collects data from the outside. The outside is an information processing device other than each terminal device. The data collected from the outside includes song information (eg, genre information) that is lacking in the playback history. The data collection timing may be periodically performed or may be performed together with the acquisition of the reproduction history. When data from the outside is collected, the process proceeds to step S63. The data collected in steps S61 and S62 is recorded in the user information management database.

  In step S63, the CPU 15 of the music providing server performs a trend analysis of each user. Specifically, the CPU 15 of the music providing server accesses the user information management database, and determines the genre type of the music being listened to (configuration of the genre of the music being listened to) and the artist type of the music being listened to (same genre). ), And the number of times played for each song (within the same genre, artist, depth of listening for each song) are obtained and compared. When the tendency analysis of each user, in other words, the type of genre of the song being listened to is acquired, the process proceeds to step S64.

  In step S64, the CPU 15 of the music providing server performs a similarity analysis. Specifically, the CPU 15 of the music providing server performs analysis 1, analysis 2, and ranking. In the analysis 1, the acquired tendencies of the respective users are compared, and the similarity is distributed in three stages. It is analyzed that the similarity is high if the genre structure is the same, the similarity is high if the favorite genre is the same, and the similarity is low if the second favorite genre is the same. In analysis 2, further detailed analysis is performed based on the analysis result of analysis 1. When both the width of the genre and the depth of listening are close, the similarity is high, the similarity is high when the listening depth is close, and the similarity is low when the width is close to the genre. The width of the genre can be expressed by the number of songs included in the genre, for example. In addition, the listening depth can be expressed by the number of reproductions. Analysis is possible by quantifying the width of the genre and the depth of listening. In the ranking, ranking is performed in descending order of similarity among similar users based on Analysis 1 and the analysis.

  As described above, the correlation creation (search by person-preference) process is executed, whereby a “preference” correlation can be obtained. For example, as shown in FIG. 17, the obtained correlation regarding preference is processed so that it can be displayed as an image diagram showing a connection between the user and another user, and is sent to the in-vehicle device 3.

(Correlation creation (search for people-scene) processing)
FIG. 25 shows an outline of processing for creating a correlation (searching for a person-scene). In the process of creating a correlation (searching for a person-scene), the “scene” button is selected on the “top screen for searching for a song from another user” shown in FIG. 17, and the CPU 31 of the in-vehicle device sends a message to that effect to the music providing server 1. It starts with that.

  In step S <b> 71, the CPU 15 of the music providing server collects data from the in-vehicle device 3. The CPU 15 of the music providing server acquires position information, a road type of the traveling road, vehicle interior information, and the like as data. The vehicle interior information includes the atmosphere, passenger presence / absence, and passenger identification. Data collection timing may be periodically performed. If data is acquired, it will progress to step S72.

  In step S72, the CPU 15 of the music providing server collects data from the outside. The outside is an information processing device other than each terminal device. Data collected from the outside includes time information, weather information, and traffic jam information. Data collection timing may be periodically performed. When data from the outside is collected, the process proceeds to step S73. The data collected in steps S71 and S72 is recorded in the user information management database.

  In step S73, the CPU 15 of the music providing server performs scene analysis. Specifically, the CPU 15 of the music providing server accesses the user information management database, and acquires and compares scenes of the respective users. Next, in step S74, the CPU 15 of the music providing server performs similarity analysis. Specifically, the CPU 15 of the music providing server first extracts users having the same or similar scene from the comparison result in step S73. For example, it is determined that the similarity is higher as the number of matching items including position information, road type of the traveling road, vehicle interior information, and the like increases. Next, ranking is performed in descending order of similarity among similar users.

  As described above, the correlation creation (search by person-scene) process is executed, whereby the correlation of the “scene” can be obtained. The obtained correlation regarding the “scene” is processed so that it can be displayed as an image diagram showing the connection between the user and another user, as shown in FIG.
