Next, the information providing apparatus 30 acquires a place name corresponding to the latitude / longitude represented by the received position data from the place name / position information database DB4 (step S6). For example, when the latitude / longitude represented by the position data is the latitude / longitude in the area specified by the position information of the record in the first row of the place name / position information database DB4 in FIG. The place name “Akihabara” stored in the record in the first row is acquired.

  Next, the information provision apparatus 30 performs the process which updates user action database DB1 (step S7). Specifically, the information providing apparatus 30 determines whether or not the received user identifier, the place name extracted from the text data in step S5 or the place name acquired in step S6, and the set of words extracted in step S5 are in the user action database DB1. Determine whether. The information providing apparatus 30 adds 1 to the value of the co-occurrence count field of the record storing these combinations when the record storing these combinations of user identifiers, place names, and words already exists in the user behavior database DB1. To do. If a record storing these sets does not exist in the user behavior database DB1, a record storing these sets is added to the user behavior database DB1, and the value of the co-occurrence number field is set to “1”.

  For example, the received user identifier is “001”, the place name acquired from the place name / position information database DB4 is “Akihabara”, and the word extracted from the text data is “home appliance”. As shown in FIG. If the information already exists in the user behavior database DB1, the information providing apparatus 30 adds 1 to the value of the co-occurrence number field of the record storing this set. Further, for example, the received user identifier is “001”, the place name acquired from the text data is “Ochanomizu”, the word extracted from the text data is “instrument”, and a record storing this set exists in the user behavior database DB1 If not, the information providing apparatus 30 newly adds a record storing this set to the user behavior database DB1.

  When the information providing apparatus 30 updates the user behavior database DB1, the information providing apparatus 30 next performs a process of updating the user correlation database DB2 (step S8). Specifically, first, the information providing apparatus 30 specifies a record storing the received user identifier in the user behavior database DB1, and extracts a combination of a place name and a co-occurrence word from the specified record. Next, the information providing apparatus 30 selects another user identifier, and counts the number of records in which the combination of the extracted place name and co-occurrence word is stored in the record storing the selected user identifier. And the information provision apparatus 30 stores the counted number in the correlation field of the record which stored the received user identifier and the selected user identifier.

For example, in the case of the user behavior database DB1 shown in FIG. 5, the information providing device 30 sets the place name “Akihabara” and the co-occurrence word “home appliance” from the record storing the user identifier “001”, and the place name “Ochanomizu”. ”And the co-occurrence word“ instrument ”, and the combination of the place name“ Akihabara ”and the co-occurrence word“ animation ”.
Next, the information providing apparatus 30 selects a user identifier “002” different from the received user identifier “001”, and in the record storing the selected user identifier, the extracted place name “Akihabara” and the co-occurrence word “ A record that stores a set of “home appliances”, a record that stores a combination of the extracted place name “Ochanomizu” and the co-occurrence word “instrument”, and a record that stores a set of the extracted place name “Akihabara” and the co-occurrence word “anime” Count.
Here, for example, when the user behavior database DB1 has the contents of FIG. 5, the records in the fourth to sixth lines are counted. Then, the information providing apparatus 30 stores “3”, which is the counted number, in the correlation field of the record in which the user identifier “001” is stored in the user correlation database DB2 and “002” is stored in the correlation user field. Store.

When the information providing apparatus 30 updates the user correlation database DB2, the information providing apparatus 30 next performs a process of updating the area information database DB3 (step S9). Specifically, first, the information providing apparatus 30 sequentially selects combinations of place names and co-occurrence words stored in the user behavior database DB1 updated in step S7, and the number of records storing the selected combinations. Count.
For example, when the combination of the place name “Akihabara” and the co-occurrence word “home appliance” is selected in the user behavior database DB1 of FIG. 5, the record storing this combination is in the first row and the fourth row. The number of records storing “2” is two. Therefore, the information providing apparatus 30 stores “2” in the number of users field of the record in which the combination of the place name “Akihabara” and the co-occurrence word “home appliance” is stored in the area information database DB3.

  When the information providing device 30 finishes updating each database, the information providing device 30 next determines information to be provided to the user of the terminal device 10. First, the information provision apparatus 30 determines the 1st information provided to a user with the 1st method shown by the flowchart of FIG. 11 (step S10). The information providing apparatus 30 searches the area information database DB3 using the place name acquired from the place name / position information database DB4 in step S6 as a search key (step SA1). Here, the information providing apparatus 30 identifies the record having the largest number stored in the number-of-users field in the record storing the place name as the search key, and determines the co-occurrence word stored in the identified record, It determines to the 1st information provided to the user of the terminal device 10 (step SA2). In this embodiment, the co-occurrence word stored in the record having the largest number stored in the user number field is determined as the first information, but the number stored in the user number field is large. A plurality of co-occurrence words may be selected in order, and the selected co-occurrence word may be determined as the first information.

  For example, when the place name “Akihabara” is acquired as the place name in step S6, the information providing apparatus 30 searches the area information database DB3 for a record including the place name “Akihabara”. Here, as shown in FIG. 7, when the place name “Akihabara” is stored in the records of the first to third lines of the area information database DB3, the records of the first to third lines are stored. Extracted. When the number of users in the record in the first line is the largest in the records in the first line to the third line, the first word that provides the user with the word “home appliance” of the co-occurrence word stored in the record in the first line Decide on information.

Next, the information provision apparatus 30 determines the 2nd information provided to a user with the 2nd method shown by the flowchart of FIG. 12 (step S11). First, the information providing apparatus 30 searches the user correlation database DB2 using the user identifier received from the terminal apparatus 10 as a search key (step SB1). The information providing apparatus 30 extracts the user identifier stored in the correlation user field of the record storing the search key and the correlation stored in the correlation field (step SB2).
For example, when the user identifier received from the terminal device 10A is “001” and the content of the user correlation database DB2 is the content of FIG. 6, the information providing device 30 determines from the record on the first row and the record on the second row. The user identifier and the correlation degree of the correlated user are extracted.

Next, the information providing apparatus 30 searches the user behavior database DB1 using both the user identifier extracted from the user correlation database DB2 in step SB2 and the place name acquired from the place name / position information database DB4 in step S6 as a search key. A record having the largest co-occurrence value is extracted from the records storing the keys (step SB3).
For example, when the information providing apparatus 30 acquires “Akihabara” as the place name in step S6 and extracts “002” and “003” as the user identifiers in step SB2, first, the record 5 in the fourth line in FIG. Extract the record on the line. Here, if the value of the co-occurrence number of the record on the fourth line is larger than the value of the co-occurrence number of the record on the fifth line, the information providing apparatus 30 extracts the record on the fourth line.
The information providing apparatus 30 also extracts a record in the seventh row that stores “003” as the user identifier and “Akihabara” as the place name. In the record having the user identifier “003”, the record storing the place name “Akihabara” is only in the seventh line, so this record is extracted.

Next, the information providing apparatus 30 determines second information to be provided to the user based on the calculation result of the product of the degree of correlation extracted in step SB2 and the number of co-occurrence stored in the record extracted in step SB3. (Step SB4).
Here, the information providing apparatus 30 calculates the co-occurrence number “C4” of the record in the fourth row extracted in step SB3 and the degree of correlation “Co1” extracted from the record in the first row of the user correlation database DB2 in step SB2. Calculate the product. Further, the information providing apparatus 30 calculates the co-occurrence number “C7” of the record in the seventh row extracted in step SB3 and the correlation degree “Co2” extracted from the record in the second row of the user correlation database DB2 in step SB2. Calculate the product. Here, when the calculation result of the product of “C7” and “Co2” is larger than the calculation result of “C4” and “Co1”, it is stored in the record storing the number of times of co-occurrence “C7” in the user behavior database DB1. The co-occurrence word “figure” is determined as second information to be provided to the user.

Next, the information provision apparatus 30 determines the 3rd information provided to a user with the 3rd method shown by the flowchart of FIG. 13 (step S12). First, the information providing apparatus 30 searches the user behavior database DB1 using a record including the user identifier received from the terminal apparatus 10 and the place name acquired from the place name / position information database DB4 in step S6 (step SC1). Next, the information providing apparatus 30 extracts a co-occurrence word included in the record having the largest value in the co-occurrence number field among the records storing the search keys (step SC2).
For example, when the user identifier received from the terminal device 10A is “001” and the place name acquired in step S6 is “Akihabara”, the record of the first row and the third row are stored in the user behavior database DB1 shown in FIG. The eye record is searched. Then, when the value of the co-occurrence number “C1” of the record in the first row is larger than the value of the co-occurrence number “C3” of the record in the third row, the information providing apparatus 30 The co-occurrence word “home appliance” included in the record on the line is extracted.

Next, the information providing apparatus 30 searches the user correlation database DB2 using the user identifier received from the terminal apparatus 10 as a search key (step SC3). The information providing apparatus 30 extracts the user identifier stored in the correlation user field of the record storing the search key and the correlation stored in the correlation field (step SC4).
For example, when the user identifier received from the terminal device 10A is “001” and the content of the user correlation database DB2 is the content of FIG. 6, the information providing device 30 determines from the record on the first row and the record on the second row. The user identifier (“002” and “003”) and the correlation degree (“Co1” and “Co2”) of the correlated user are extracted.

Next, the information providing apparatus 30 searches the user behavior database DB1 using the user identifier of the correlated user extracted in step SC4 and the co-occurrence word extracted in step SC2 as a search key, and extracts a record storing the search key. (Step SC5).
For example, when the user identifier “002” of the correlated user extracted in step SC4 and the co-occurrence word “home appliance” are used as search keys, the information providing apparatus 30 extracts the record in the fourth line in FIG. When the extracted user identifier “003” of the correlated user and the co-occurrence word “home appliance” are used as search keys, the record in the ninth line in FIG. 5 is extracted.
