  In addition, when the posted data that is viewed is preferable, the user who browses the posted data can make a positive evaluation (“Like”) on the posted data. Generally, post data with high reliability increases the number of users who positively evaluate the post data (the number of “likes”).

  In addition, the post data can include a facility tag in the form of “# facility name” in which a predetermined symbol (for example, #) and a facility name are combined. This facility tag indicates that the posted data is information about a specific facility. For example, when the facility tag “# Hyogo-ji” is included in the posted data, it can be clearly indicated that the posted data is information relating to the facility “Hyogo-ji”.

<1-4. Database>
Next, the two databases 51 and 52 stored in the storage unit 43 of the management server 4 will be described.

  First, the posting database 51 will be described. The posting database 51 stores a large number of posting data posted by SNS users. Information related to one post data is registered as one record in the post database 51.

  FIG. 5 is a diagram showing an example of one record (hereinafter referred to as “post record”) TR in the post database 51. In the posting database 51, such posting records TR are accumulated for each posting data.

  As shown in the figure, the posting record TR includes “posting ID”, “posting date / time”, “posting data”, “facility tag”, “posting position”, “poster name”, “number of viewers”, “number of positive evaluations”, and the like. Contains information.

  “Post ID” is identification information for identifying post data. “Posted date / time” is the date and time when posted data is posted. “Posted data” is text data indicating the content of the posted data. The “facility tag” is an extraction of only the facility tag when the facility tag is included in the posted data.

  “Post position” is position information added to post data. “Contributor name” is the name of the user who posted the posted data. “Number of viewers” is the number of other users (followers) who specify (follow) the user who posted the posted data. The “number of positive evaluations” is the number of users who positively evaluated the posted data (the number of “likes”).

  Next, the facility database 52 will be described. The facility database 52 stores facility data relating to a plurality of facilities that are candidates for destinations. Facility data relating to one facility is registered as one record in the facility database 52.

  FIG. 6 is a diagram showing an example of one record (hereinafter referred to as “facility record”) PR of the facility database 52. In the facility database 52, such facility records PR are stored for each facility. As shown in the figure, the facility data included in the facility record PR is roughly divided into basic data D1, additional data D2, and evaluation data D3.

  The basic data D1 is basic information of the facility of the facility record PR, and includes “facility ID”, “facility name”, and “facility position”. “Facility ID” is identification information for identifying a facility. “Facility name” is the name of the facility. The “facility position” is position information (latitude and longitude) indicating the position of the facility. It can be said that the basic data D1 is fixed information regarding the facility of the facility record PR.

  On the other hand, the additional data D2 is information added based on SNS post data (tweet). The additional data D2 includes “post data” and “related words”.

  “Posted data” is post data related to the facility of the facility record PR among the posted data posted to the SNS. Which facility the SNS post data relates to is determined by a facility tag included in the post data. The facility record PR includes not only all the posted data posted in the past regarding the facility of the facility record PR but only the posted data posted in the latest fixed period (for example, one week).

  The “related word” is a keyword extracted from post data included in the facility record PR. This keyword is included in the facility record PR as a related word related to the facility of the facility record PR. Such a related word is extracted from post data for the most recent fixed period (for example, for one week). Therefore, the related word includes a keyword (for example, “autumn leaves”, “best time”, etc.) indicating timely matters at that time, such as “best time for colored leaves”.

  The evaluation data D3 is information indicating an evaluation value and a comprehensive evaluation value for the facility, post data, and related words of the facility record PR. Each of the evaluation values is represented by, for example, 10 levels (any one of 1 to 10).

  Regarding facilities, there are two evaluation values (evaluations a and b). A value obtained by summing these two evaluation values (evaluations a and b) is a comprehensive evaluation value V1 of the facility.

  “Evaluation a” is an evaluation value corresponding to the number of post data included in the facility record PR (the number of post data for the latest fixed period). The “evaluation a” increases as the number of post data increases.

  In addition, “evaluation b” corresponds to the total number of users who have positively evaluated the posted data included in the facility record PR (the number of “likes”) (the total number of “positive evaluations” in FIG. 5). Evaluation value. The “evaluation b” increases as the total number of positively evaluated users increases.

  Regarding post data, there are four evaluation values (evaluations a to d) for each post data. A value obtained by summing these four evaluation values (evaluations a to d) becomes a total evaluation value V2 of each posting data.

  “Evaluation a” is an evaluation value corresponding to the elapsed time from the date and time when the posting data was posted (“posting date and time” in FIG. 5). The shorter the elapsed time (the newer the posted data), the higher the “evaluation a”.

  “Evaluation b” is an evaluation value corresponding to the number of other users (followers) who specify (follow) the user who posted the posted data (“number of viewers” in FIG. 5). The “evaluation b” increases as the number of other users who specify the posted users increases.

  “Evaluation c” is an evaluation value corresponding to the distance between the position where the posting data is posted (“posting position” in FIG. 5) and the position of the facility (“facility position” in the basic data D1). The shorter the distance between the posted position and the facility position, the higher the “evaluation c”.

  “Evaluation d” is an evaluation value according to the number of users who positively evaluated the posted data (the number of “likes”) (“positive evaluation number” in FIG. 5). The “evaluation d” increases as the number of positively evaluated users increases.

  Regarding related words, there are two evaluation values (evaluations a and b) for each related word. A value obtained by summing up these two evaluation values (evaluations a and b) becomes a total evaluation value V3 of each related word.

  “Evaluation a” is an evaluation value corresponding to the number of pieces of post data including a related word among post data included in the facility record PR. The “evaluation a” increases as the number of pieces of post data including related words increases.

  “Evaluation b” is an evaluation value corresponding to the average value of the overall evaluation value V2 of the posting data including the related word among the posting data included in the facility record PR. The “evaluation b” increases as the average value of the overall evaluation values of the posted data increases.

<1-5. Registration of related words>
Next, processing for registering a related word in each facility record PR in the facility database 52 will be described. The process of registering the related word is executed by the word registration unit 41b of the management server 4 every predetermined time (for example, every day).

  First, the word registration unit 41b performs processing (post data classification processing) for classifying post data into related facility records PR (post data classification processing), and then updates the content for each facility record PR (facility record update processing). ). Hereinafter, each processing will be described.

  First, the post data classification process will be described. FIG. 7 is a diagram showing the flow of post data classification processing. The posted data classification process is a process for classifying each posted data into related facility records PR for all posted data posted to the SNS from the previous process to the current process.

  First, the word registration part 41b reads the posting record TR of one posting data among the posting data of object from the posting database 51 (step S11).

  Next, the word registration unit 41b refers to the “facility tag” of the read post record TR and determines whether or not the post tag includes a facility tag (step S12). Thereby, the word registration part 41b discriminate | determines whether posting data are the information about a specific plant | facility. If the post data does not include a facility tag (No in step S12), the process proceeds directly to step S17.

  On the other hand, when the facility tag is included in the posted data, next, the word registration unit 41b determines whether or not the facility record PR for the facility indicated by the facility tag exists in the facility database 52 (step S13). ).

  If the facility record PR exists in the facility database 52 (Yes in step S13), the word registration unit 41b reads the facility record PR (step S14), and puts the posted data in the read facility record PR. It adds (step S16). Then, the process proceeds to step S17.

  On the other hand, if the facility record PR does not exist in the facility database 52 (No in step S13), the facility indicated by the facility tag is a new facility that is different from a plurality of facilities already registered in the facility database 52. (Hereinafter referred to as “unregistered facility”). In this case, the word registration unit 41b newly creates a facility record PR related to an unregistered facility under a specific condition, and registers the unregistered facility in the facility database 52 (step S15).

  Specifically, the word registration unit 41b is a specific term indicating that the posted data is a post from an unregistered facility, such as “I am in (unregistered facility)” or “I will post from (unregistered facility)”. Is included in the “post data” of the post record TR. And when such a specific term is included in “post data”, the facility record PR having the facility name and “post position” of the unregistered facility in the post record TR as “facility name” and “facility location”, respectively. Create a new.

  For example, in the posted record TR shown in the upper part of FIG. 8, the unregistered facility indicated by the facility tag is “Shin-Kobe Park”, and the “post data” includes the specific term “I am in Shin-Kobe Park”. Therefore, in this case, as shown in the lower part of FIG. 8, a facility record PR having “Shin-Kobe Park” as “facility name” and “posting position” of the posting record TR as “facility position” is newly created. . At the time when the facility record PR is created, the additional data D2 and the evaluation data D3 of the facility record PR are Null. Thus, since the facility record PR including the facility data regarding the unregistered facility is newly created, the newly opened facility can be additionally registered in the facility database 52.

  Returning to FIG. 7, when the facility record PR is newly created using the posted data, the word registration unit 41b then adds the posted data to the created facility record PR (step S16). Then, the process proceeds to step S17.

  In step S <b> 17, the word registration unit 41 b determines whether or not the processing related to all post data as targets has been completed. If there is post data that has not been processed (No in step S17), the process returns to step S11, and the same process as described above is executed for the new post data. When such processing is repeated and the classification of all the posted data items to be processed is completed (Yes in step S17), the posted data classification process is completed.

  Next, the facility record update process will be described. FIG. 9 is a diagram showing a flow of facility record update processing. The posted data classification process is a process for updating all the facility records PR included in the facility database 52 based on the posted data added for each facility record PR.

  First, the word registration unit 41b reads out one facility record PR among all the facility records PR included in the facility database 52 (step S21).

  Next, the word registration unit 41b deletes post data that has expired after a certain period (for example, one week) from the post data included in the read facility record PR (step S22). As a result, the facility record PR includes only post data for the most recent fixed period.

  Next, the word registration unit 41b derives two evaluation values (evaluations a and b) and a comprehensive evaluation value V1 related to the facility of the facility record PR, and adds them to the facility record PR (step S23). The word registration unit 41b derives “evaluation a” based on the number of post data included in the facility record PR, and based on the total number of users who positively evaluated the post data included in the facility record PR. Deriving an evaluation “b”. Then, the word registration unit 41b adds up these “evaluation a” and “evaluation b” to derive a comprehensive evaluation value V1.

  Next, the word registration unit 41b derives four evaluation values (evaluations a to d) and a comprehensive evaluation value V2 for each posted data included in the facility record PR, and adds them to the facility record PR (step S24). . The word registration unit 41b derives “evaluation a” based on the elapsed time from the date and time when the posting data is posted to the time point, and determines “evaluation b” based on the number of other users who specify the user who posted the posting data. Is derived. In addition, the word registration unit 41b derives “evaluation c” based on the distance between the location where the posted data is posted and the location of the facility, and “evaluation d” based on the number of users who positively evaluated the posted data. Is derived. Then, the word registration unit 41b derives a comprehensive evaluation value V2 by adding these “evaluation a”, “evaluation b”, “evaluation c”, and “evaluation d”.

  Next, the word registration part 41b extracts the related word relevant to the said facility from the contribution data contained in the facility record PR (step S25). For example, the word registration unit 41b divides a sentence of post data into words, and extracts related words by deleting non-terms such as particles and conjunctions.

  The word registration unit 41b performs such extraction of related words with respect to all post data included in the facility record PR. Duplicate extracted related words are deleted, and only one identical related word is extracted. And the word registration part 41b deletes all the related words already contained in the facility record PR, and adds the newly extracted related word to the facility record PR. Thereby, only the related word extracted from the contribution data of the latest fixed period is contained in the facility record PR. By adding the related word to the facility record PR in this way, the related word related to the facility is registered in the facility database 52 in association with the facility.

  Next, the word registration unit 41b derives two evaluation values (evaluation a, b) and a comprehensive evaluation value V3 for each related word included in the facility record PR, and adds them to the facility record PR (step S26). . The word registration unit 41b derives “evaluation a” based on the number of pieces of post data including the related word, and “evaluation” based on the average value of the total evaluation values V2 of the post data including the related word. b "is derived. And the word registration part 41b adds up these "evaluation a" and "evaluation b", and derives | leads-out the comprehensive evaluation value V3.

  Next, the word registration unit 41b determines whether or not the processing related to all target facility records PR has been completed. If there is a facility record PR that has not been processed (No in step S27), the process returns to step S21, and the same processing as described above is executed for the new facility record PR. When such processing is repeated and the update of all target facility records PR is completed (Yes in step S27), the facility record update processing ends.

<1-6. Destination settings>
Next, processing for setting the destination of the navigation device 2 using such a facility database 52 will be described. FIG. 10 is a diagram showing a flow of processing for setting the destination of the navigation device 2. The left side in the figure is the process of the navigation device 2, and the right side in the figure is the process of the management server 4. Prior to the start of these processes, the navigation apparatus 2 and the management server 4 can perform data communication through a predetermined authentication process and the like.

  First, the destination setting unit 21a of the navigation device 2 accepts a search condition for searching for a facility that is a destination candidate from the user (step S31). At this time, a screen for inputting search conditions is displayed on the display 23, and the user inputs the search conditions to the navigation device 2 by operating the operation unit 24 while referring to this screen. The search condition includes a search text, a distance condition (for example, within 10 km), and the like. The search text may be one or more search words, which are keywords for search, or a sentence including one or more search words.

  Next, the destination setting unit 21a of the navigation device 2 transmits the received search condition together with the current position of the vehicle 9 (the position of the navigation device 2) to the management server 4 via the data communication unit 22 (step S32). ). The search condition transmitted from the navigation device 2 in this way is received by the data communication unit 42 of the management server 4 and accepted by the facility extraction unit 41c (step S41).

  Upon receiving the search condition, the facility extraction unit 41c determines whether or not the search text included in the search condition is a sentence (step S42). When the search text is a sentence (in step S42), the facility extraction unit 41c divides the search text into words and deletes insignificant terms such as particles and conjunctions, thereby obtaining one or more search words. Is extracted (step S43). When the search text is not a sentence but one or more search words, the search word is used as it is in the subsequent processing.

  Next, the destination setting unit 21a searches for related words included in each facility record PR in the facility database 52 using one or more search words (step S44). Thereby, the destination setting part 21a extracts the facility relevant to a search word. That is, the destination setting unit 21a extracts the facility of the facility record PR including the related word that matches one of the one or more search words. By such processing, a plurality of candidate facilities are usually extracted as facilities related to the search word.

  Next, the destination setting unit 21a narrows down the extracted candidate facilities using a search condition other than the search text (step S45). For example, the destination setting unit 21a narrows down candidate facilities to only facilities that exist within a predetermined distance from the current position of the vehicle 9 according to a distance condition (for example, within 10 km) that is one of the search conditions. Such search conditions may include facility type conditions (stores, accommodation facilities, public facilities, cultural facilities, etc.) and time conditions (business hours, etc.). Thereby, the candidate facilities of the destination are narrowed down to the facilities that match the search condition.

  Next, the order setting unit 41d sets priorities of a plurality of candidate facilities (step S46). Such priority setting need only be executed when there are a plurality of candidate facilities as facilities related to the search word, and need not be executed when there is only one candidate facility. The rank setting unit 41d derives three evaluation values (word evaluation value, distance evaluation value, and SNS evaluation value) for each of a plurality of candidate facilities. Then, the rank setting unit 41d sets priorities of a plurality of candidate facilities based on the total score of the derived three evaluation values. Each of these three evaluation values is represented by, for example, 10 levels (any one of 1 to 10).

  The word evaluation value is an evaluation value corresponding to the total value of the comprehensive evaluation values V3 of related words that match the search word when the candidate facility is extracted. The word evaluation value is higher as the candidate facility is more relevant to the search word.

  The distance evaluation value is an evaluation value corresponding to the distance from the current position of the vehicle 9 to the candidate facility. The distance evaluation value becomes higher as the candidate facility is closer to the current position of the vehicle 9.

  The SNS evaluation value is an evaluation value corresponding to the overall evaluation value V1 of the candidate facility. The SNS evaluation value is higher as the candidate facility has a higher overall evaluation value V1 described above.

  As described above, the comprehensive evaluation value V1 of the facility is derived based on post data regarding the facility to the SNS. Specifically, the overall evaluation value V1 of the facility is “evaluation a” corresponding to the number of post data regarding the facility and “evaluation b” corresponding to the total number of users who positively evaluated the post data regarding the facility. And the total value.

  Therefore, the order setting unit 41d sets the priority order of the plurality of candidate facilities based on the posted data of each of the plurality of candidate facilities. For this reason, evaluation in SNS can be reflected in the priority order of a plurality of candidate facilities. That is, since a candidate facility with a large number of post data relating to the facility has a higher priority, the priority of a candidate facility popular with SNS users can be increased. Moreover, since a candidate facility with a high total of the number of the users who evaluated the posting data regarding the facility in a positive manner has a higher priority, it is possible to increase the priority of a candidate facility highly evaluated by the SNS user.

  When the priorities of the plurality of candidate facilities are set, the destination setting unit 21a next calculates the facility record PR including the facility data of each of the extracted plurality of candidate facilities and the priorities of the plurality of candidate facilities. Then, the data is transmitted to the navigation device 2 via the data communication unit 42 (step S47). The facility records PR and the priorities of the plurality of candidate facilities transmitted from the management server 4 in this way are received by the data communication unit 22 of the navigation device 2 and accepted by the destination setting unit 21a (step S33).

  Next, the destination setting unit 21a displays a list of “facility names” of the plurality of candidate facilities on the screen of the display 23 using the received facility records PR of the plurality of candidate facilities (step S34). At this time, the “facility names” of the plurality of candidate facilities are displayed on the screen of the display 23 in descending order of priority among the plurality of candidate facilities. Therefore, the navigation apparatus 2 can display “facility names” of a plurality of candidate facilities related to the search word in a priority order reflecting the evaluation by the SNS. The user can select one facility by operating the operation unit 24 while referring to this screen.

  The destination setting unit 21a sets the facility selected by the user from the plurality of candidate facilities in this way as the destination for route guidance (step S35). The destination setting unit 21a sets the destination based on the “facility position” included in the facility record PR of the selected facility.

  FIG. 11 is a diagram showing a screen of the display 23 on which a plurality of candidate facilities are displayed as a list. As shown in the figure, on the screen of the display 23, a facility button B1 indicating "facility names" of a plurality of candidate facilities, an evaluation point reference button B2, a posting reference button B3, and a destination setting button B4 are displayed. Has been. The facility button B1 is displayed according to the priority order of the corresponding candidate facilities.

  The user can instruct the navigation device 2 by touching these command buttons B1 to B4 displayed on the screen by the function of the operation unit 24 as a touch panel. When the user touches one of the facility buttons B1 and further touches the destination setting button B4, the facility corresponding to the facility button B1 touched by the user is set as the destination.

  When the user touches the evaluation point reference button B2 on the screen of FIG. 11, the evaluation values of the plurality of candidate facilities are displayed on the screen of the display 23 as shown in FIG. That is, the word evaluation value, the distance evaluation value, the SNS evaluation value, and the total evaluation value that is the total value of each of the plurality of candidate facilities are displayed. The user can refer to such an evaluation value when selecting a destination facility. Further, when the user touches the return button B5 included in this screen, the screen of the display 23 returns to the screen of FIG.

  When the user touches any of the facility buttons B1 on the screen of FIG. 11 and further touches the posting reference button B3, as shown in FIG. 13, candidate facilities corresponding to the facility button B1 touched by the user are displayed. The post data included in the facility record PR is displayed. The posted data is displayed in order from the highest overall evaluation value V2. The user can refer to such posted data when selecting a destination facility. If the user touches the return button B6 included in this screen, the screen of the display 23 returns to the screen of FIG.

  As described above, in the information processing system 10 according to the present embodiment, the management server 4 stores the facility database 52 including facility data regarding each of a plurality of facilities. The word registration unit 41b of the management server 4 registers the related word included in the posting data regarding any of the plurality of facilities posted to the SNS in the facility database 52 in association with the facility. In addition, the facility extraction unit 41c of the management server 4 performs a search for related words using the search word received from the navigation device 2, and extracts a facility related to the search word from a plurality of facilities. Then, the data communication unit 42 of the management server 4 transmits the facility data of the facility extracted in this way to the navigation device 2.

  Thus, in the information processing system 10, since the facility related to the search word is extracted using the related word included in the SNS post data, the facility can be extracted based on the latest information. Therefore, it is possible to extract facilities related to timely matters at that time, such as “famous autumn leaves”. Since the facility data of the facility can be provided to the navigation device 2, the navigation device 2 can set the facility as a destination.

  Moreover, since the word registration part 41b associates only the related word contained in the post data of the latest fixed period with the facility, the old post data is not used, and the facility can be extracted based on the latest information.

  In addition, the posting data to the social networking service is used not only for general browsing but also for setting a destination in the navigation device 2. For this reason, new enjoyment can be given to the user who posts the posting data.

  In addition, the nature of social networking services is reflected in the extraction results of candidate destination facilities. For this reason, by setting the nature of the social networking service to be used, it is possible to easily extract candidate facilities that meet the user's preference. For example, if the information processing system 10 uses a social networking service for young people, the information processing system 10 can be a system that can easily extract candidate facilities for young people.

<2. Second Embodiment>
