  The server 10 of the present embodiment is a server that acquires information provided from the mobile terminal 20 and provides various services using this information. Services provided by the server 10 include, for example, a type of service that allows browsing of restaurant rankings or gourmet guides based on third-party reviews and score evaluations, and third-party services such as Twitter (registered trademark). There are types of services that allow browsing of posted content, and types of services that allow browsing of rankings of accommodation facilities based on third-party reviews such as Rakuten Travel (registered trademark). Hereinafter, the server 10 of the present embodiment will be described as a server that provides a service capable of browsing a restaurant evaluation based on third-party word-of-mouth information.

  The server 10 includes a CPU 110, a ROM 120, a RAM 130, a hard disk 140, and a communication unit 150, which are mutually connected by a bus. The communication unit 150 can communicate with the mobile terminal 20 via the Internet INT.

  The CPU 110 functions as an information acquisition unit 111, an evaluation unit 112, and a service providing unit 113 by developing and executing a computer program stored in the ROM 120 on the RAM 130.

  The information acquisition part 111 acquires the word-of-mouth communication of the restaurant as local information from a user. In the present embodiment, “region information” means information about a region. “Region” means a range of land delimited by some criteria. For example, the area may be determined according to administrative divisions of local governments such as municipalities, or may be determined by dividing an area on a map into a mesh shape. The region information may be anything as long as it is information related to the region. In addition to reviews of restaurants located in a specific region as in this embodiment, for example, reviews of schools located in a specific region, specific regions Adopting reviews of historical sites of tourists, reviews of leisure facilities located in a specific area, reviews of folk crafts and crafts rooted in a specific area, reviews of road congestion in a specific area, etc. May be.

  The evaluation unit 112 evaluates the area information acquired by the information acquisition unit 111. Details will be described later.

  The service providing unit 113 realizes a service using the area information acquired by the information acquiring unit 111. Specifically, the service providing unit 113 acquires a plurality of mobile terminals 20 by using the area information acquired by the information acquiring unit 111 and stored in the posted information table 144 through a post evaluation process described later as “evaluation of restaurant”. Can be viewed from The service providing unit 113 enables browsing of restaurant evaluations in the form of a WEB (World Wide Web) page using, for example, HTTP (HyperText Transfer Protocol). The service providing unit 113 corresponds to a “providing unit” in the claims, and the mobile terminal 20 that browses the evaluation of the restaurant corresponds to a “client device” in the claims.

  The hard disk 140 includes an everyday area table 141, an area characteristic table 142, a facility table 143, and a posting information table 144.

  FIG. 2 is an explanatory diagram showing an example of the daily life table 141. The daily area table 141 is stored in the hard disk 140 in advance in a state in which the value of each entry is registered. The daily area table 141 includes a user identifier, a user name, and an everyday area.

  “User identifier” is an identifier for uniquely identifying a user. As the user identifier, for example, an enumeration of random character strings, a telephone number, a mail address, or the like can be used. “User name” is a nickname of the user. The user name is specified by the user.

  The “daily life zone” is an area determined based on the user's behavior history. In other words, the daily life area means the user's activity area, for example, the vicinity of the user's residence, the vicinity of the user's school or workplace, the place where the user frequently visits, and the vicinity. . In other words, daily life means an area where the user is geographically familiar. The daily zone is acquired and stored in advance by the server 10. Specifically, the server 10 periodically receives positioning information including a positioning point (current position) specified by the current position acquisition unit 210 of the mobile terminal 20, a positioning time, and a user identifier. Based on the received positioning information, the server 10 sets a region where a positioning point to be positioned exceeding a predetermined frequency exists or a region where a positioning point exists beyond a predetermined number of days as a daily zone.

  For example, in the example of FIG. 2, the user “Akane” specified by the user identifier User001 is found to have Nagoya City, Aichi Prefecture and Gamagori City, Aichi Prefecture as daily areas (entries E01, E02). As described above, a plurality of daily zones can be set for one user. The daily life table 141 corresponds to the “daily life storage unit” in the claims.

  FIG. 3 is an explanatory diagram illustrating an example of the regional characteristic table 142. The regional characteristic table 142 is stored in the hard disk 140 in advance in a state where the value of each entry is registered. The area characteristic table 142 includes area names and area characteristics.

  “Regional characteristics” means characteristics associated with a region. The characteristics associated with a region broadly include special products located in the region and names of features located in the region. The regional characteristics include food and drinks that are famous in a specific area as in this embodiment, for example, the name of a school located in a specific area, the name of a historical landmark in a specific area, and a specific area. The name of an excursion facility located in the city, the name of a craft or craft that is rooted in a specific area, the name of a road located in a specific area, etc. may be adopted.

  For example, in the example of FIG. 3, the famous foods and drinks in the area whose area name is specified in Nagoya City, Aichi Prefecture are Miso Katsutoshi, Hitsumabushi, Kishimen, Hatcho Miso, Miso Stewed Udon, and Moriguchizuke. (Entries E11 to 16). Thus, a plurality of regional characteristics can be set for one region. In addition, by using a wild card for the area name, a special product that covers a wide area may be set. For example, entry E17 indicates that the famous food and drink in all the cities of Osaka Prefecture is okonomiyaki. In the example of FIG. 3, the case where the area is determined according to the administrative division of the local government is illustrated. However, for example, when a region is defined by a region on a map obtained by dividing the region into meshes, a region characteristic can be associated with each mesh on the map. Also, an arbitrary region can be set by integrating a plurality of meshes associated with region characteristics. The regional characteristic table 142 corresponds to the “regional characteristic storage unit” in the claims.

  FIG. 4 is an explanatory diagram illustrating an example of the facility table 143. The facility table 143 is stored in the hard disk 140 in advance in a state where the value of each entry is registered. The facility table 143 includes a facility identifier, a facility name, an address, a facility characteristic, a budget, and an average score.

  The “facility identifier” is an identifier for uniquely identifying a facility. “Facility name” is the name of the facility. “Address” is an address indicating the location of the facility. “Facility characteristics” means characteristics associated with a facility. The characteristics associated with a facility include a wide variety of dishes, specialties, service names, etc. that are mainly handled by the facility. In the present embodiment, the facility characteristic is the name of a dish or food that is handled with great care in a restaurant (facility). “Budget” is an average budget required for using the facility. The “average score” is a numerical value obtained by averaging evaluations about facilities received from users.

  For example, in the example of FIG. 4, it can be seen that a restaurant called Heisei Shokudo specified by the facility identifier S0001 is located in Naka-ku, Nagoya, Aichi Prefecture. Furthermore, the Heisei Shokudo has a facility characteristic of “Hitsumabushi” and “Sushi”, and it is understood that the average budget required for use is 2000 to 3000 yen. Furthermore, it can be seen that the average score of Heisei Cafeteria is 4.2 points (entry E21). In the example of FIG. 4, the location of the facility is described as an address (city / town / village) according to the administrative division of the local government. However, the location of the facility may be specified by a mesh on the map. The facility table 143 corresponds to a “facility characteristic storage unit” in the claims.

  FIG. 5 is an explanatory diagram showing an example of the posting information table 144. Each entry in the posted information table 144 is a region information (from the mobile terminal 20 to the server 10) that is transmitted from the mobile terminal 20 to the server 10 by a word-of-mouth registration operation (hereinafter also simply referred to as “word-of-mouth registration”) for a restaurant performed by the user of the mobile terminal 20. (Regional information acquired by the information acquisition unit 111)). Details will be described later. The posting information table 144 includes a user identifier, a facility identifier, a title, a text, a score, and authenticity.

  The “user identifier” is preliminarily assigned to the user who registered the word-of-mouth (regional information) (hereinafter referred to as “poster” in order to distinguish the user who registered the word-of-mouth from the user for browsing). The assigned user identifier (FIG. 2). The “facility identifier” is a facility identifier (FIG. 4) assigned in advance to a restaurant for which word-of-mouth (regional information) is registered (hereinafter referred to as a “target facility”). ). “Title” is the title of the word of mouth (regional information), and is an arbitrary character string input by the contributor. The “text” is the text of the word of mouth (regional information) and is an arbitrary character string input by the contributor. The “score” is the score of the target facility given by the poster. “Credibility” is the credibility of word of mouth (regional information). The credibility is an evaluation given by the evaluation unit 112 through a post evaluation process described later.

  The posted information table 144 corresponds to an “information storage unit” in the scope of claims, and the “credibility” in the posted information table 144 corresponds to “evaluation” in the scope of claims.

A-2. Post evaluation process:
FIG. 6 is a flowchart illustrating an example of the procedure of the post evaluation process. FIG. 7 is an explanatory diagram showing a state in which the server 10 evaluates the credibility of the word of mouth (regional information) by the post evaluation process.

  In step S <b> 102 of FIG. 6, the information acquisition unit 111 of the server 10 receives the word-of-mouth (region information) transmitted from the mobile terminal 20. The area information RI1 in FIG. 7 shows an example of the area information received by the information acquisition unit 111 in step S102 in FIG.

  In step S104 of FIG. 6, the evaluation unit 112 of the server 10 obtains the daily sphere of the poster of the area information. Specifically, the evaluation unit 112 searches the daily area table 141 for an entry having a user identifier that matches the user identifier included in the area information. In the example of FIG. 7, it is understood that the daily areas of the user identifier User001 who is the poster of the regional information are Nagoya City, Aichi Prefecture, and Gamagori City, Aichi Prefecture.

In step S <b> 106 of FIG. 6, the evaluation unit 112 of the server 10 determines whether the regional information is information regarding regional characteristics associated with the poster's daily sphere.
Specifically, first, the evaluation unit 112 searches for the following (i) and (ii).
(I) The area characteristic table 142 is searched for an area characteristic associated with the area name including the daily sphere of the poster of the area information. Here, “the daily area is included” means that the daily area of the poster of the area information and the area name in the area characteristic table 142 partially match.
(Ii) From the facility table 143, the facility characteristic of the area information, that is, the facility characteristic of the restaurant that is the subject of word-of-mouth registration is searched.
Then, the evaluation unit 112 determines whether or not the regional characteristic (i) and the facility characteristic (ii) are related. Here, “related” means including a case where it is determined as a result of a so-called fuzzy search.

  In the example of FIG. 7, (i) as the regional characteristics associated with Nagoya City, Aichi Prefecture, which is the daily sphere of the poster of the local information, the search is miso katsu, hitsumabushi, kishimen, haccho miso, miso stewed udon, and Moriguchizuke. Is done. Further, greenhouse oranges are searched as a regional characteristic associated with Gamagori City, Aichi Prefecture, which is the daily sphere of posters of regional information. Further, in the example of FIG. 7, (ii) as a facility characteristic associated with the Heisei cafeteria, which is the target facility of the area information, is searched for “Hitsumabushi” and “Kashiwa”. Since the eyelid of (i) and the eyelid of (ii) match, the evaluation unit 112 determines “relevant” in step S108.

  In step S108 of FIG. 6, the evaluation unit 112 of the server 10 receives the result of step S106 and determines whether there is a relationship. When it is determined that there is a relationship (step S108: YES), the evaluation unit 112 evaluates the credibility of the regional information as “high” (step S110). On the other hand, when it is determined that there is no relation (step S108: NO), the evaluation unit 112 evaluates the credibility of the regional information as “low” (step S112). Thereafter, the evaluation unit 112 stores the regional information to which the credibility as the evaluation is added in the posted information table 144, and ends the process.

  As described above, according to the first embodiment, the evaluation unit 112 evaluates regional information, which is information related to a region, using the daily area indicating the activity area of the poster (the user who provided the regional information). To do. For this reason, the evaluation unit 112 can use the activity region of the poster, that is, whether or not to know the region well as a reference for evaluating the regional information. Specifically, the evaluation unit 112 evaluates the credibility of the regional information using regional characteristics indirectly associated with the poster's daily sphere. As a result, the evaluation unit 112 can evaluate the area information provided by the “person who knows the area well” as having high credibility.

  Moreover, according to 1st Embodiment, the evaluation part 112 accumulate | stores the regional information acquired from the contributor and the evaluation (credibility) about the regional information in the contribution information table 144 (information storage part). Can do. And the service provision part 113 can display the regional information accumulate | stored in the contribution information table 144 on the some portable terminal 20 (client apparatus) as "evaluation of a restaurant." Thus, even if the evaluation unit 112 is regional information regarding a facility located in a specific region, the evaluation unit 112 can display regional characteristics indirectly associated with the daily sphere of the poster (the user who provided the regional information). Can be used to evaluate. For this reason, the evaluation part 112 can evaluate the information provided from "the person who knows the area well" as a thing with high credibility.

B. Second embodiment:
In the second embodiment of the present invention, a configuration that enables the evaluation of the user who provided the area information in the evaluation system of the first embodiment will be described. Below, only the part which has a different structure and operation | movement from 1st Embodiment is demonstrated. In the figure, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment described above, and detailed description thereof is omitted.

B-1. System outline:
FIG. 8 is an explanatory diagram showing a schematic configuration of an evaluation system 1000a using the evaluation apparatus as the second embodiment. The difference from the first embodiment shown in FIG. 1 is that a server 10 a is provided instead of the server 10. The server 10 a includes a CPU 110 a instead of the CPU 110 and a hard disk 140 a instead of the hard disk 140.

  The CPU 110a includes an evaluation unit 112a instead of the evaluation unit 112. In addition to the post evaluation process (FIG. 6) described in the first embodiment, the evaluation unit 112a further performs a user evaluation process described later. The user evaluation process is a process of accepting a poster's evaluation by a third party.

  The hard disk 140 a includes a daily area table 141 a instead of the daily area table 141, and a posted information table 144 a instead of the posted information table 144.

  FIG. 9 is an explanatory diagram illustrating an example of the daily area table 141a according to the second embodiment. The daily area table 141a includes support points in addition to the user identifier, the user name, and the daily area.

  The “support point” is an evaluation given to the user identified by the user identifier for each daily area of the user. The support point is given by the evaluation unit 112a via a user evaluation process B described later. In the present embodiment, the support point adopts a point addition method from 0 points. For this reason, the higher the numerical value of the support point, the higher the evaluation of the user, in other words, the higher the familiarity of the user with the daily life zone.

  For example, in the example of FIG. 9, the user “Akane” identified by the user identifier User001 has 18 support points for Nagoya City, Aichi Prefecture, and 0 support points for Gamagori City, Aichi Prefecture. Yes (entries E51, E52). The support point corresponds to “area evaluation” in the claims.

  FIG. 10 is an explanatory diagram illustrating an example of the posting information table 144a according to the second embodiment. The posting information table 144a includes a local identifier in addition to the user identifier, the facility identifier, the title, the text, the score, and the credibility.

  “Local classification” is information indicating whether or not the word-of-mouth (regional information) of the entry is information related to the poster's daily area. In the local classification, “Y” is stored when the area information is information related to the poster's daily area, and “N” is stored when the area information is not information related to the poster's daily area. The local classification is given by the evaluation unit 112a through a user evaluation process A described later.

B-2. Post evaluation process:
The post evaluation process in the second embodiment is the same as that in the first embodiment shown in FIG. Note that the post evaluation process of the second embodiment is executed as a subroutine of the user evaluation process.

B-3. User evaluation process:
The user evaluation process includes a user evaluation process A for determining whether or not the word-of-mouth (regional information) is information related to the poster's daily sphere, and a user evaluation process for accepting a poster's evaluation by a third party B.

B-3-1. User evaluation process A:
FIG. 11 is a flowchart showing the procedure of the user evaluation process A. FIG. 12 is an explanatory diagram showing a state in which the server 10a evaluates a poster by a user evaluation process.

  In step S202 of FIG. 11, the evaluation unit 112a of the server 10a executes the post evaluation process (FIG. 6) triggered by the information acquisition unit 111 receiving a word of mouth (regional information). The area information RI2 in FIG. 12 shows an example of the area information evaluated in step S202 in FIG. Here, the value of the local classification field has not yet been determined.

In step S204 in FIG. 11, the evaluation unit 112a of the server 10a determines whether the “region” of the region information is included in the daily sphere of the poster. Specifically, first, the evaluation unit 112a searches for the following (a) and (b).
(A) From the facility table 143, the address of the restaurant that is the subject of word-of-mouth registration is searched as information indicating the area of the area information.
(B) The daily area of the poster of the area information is searched from the daily area table 141a.
And the evaluation part 112a determines whether the address of the restaurant of (a) is included in the address (area name) of the daily life area of (b). Here, “included” means that the address of the restaurant and the address in the daily life are allowed to partially match.

  In the example of FIG. 12, (a) Naka-ku, Nagoya-shi, Aichi Prefecture, which is the area of the area information, is searched. Further, (b) Nagoya City, Aichi Prefecture, and Gamagori City, Aichi Prefecture, which are the daily sphere of the poster of the regional information, are searched. The evaluation unit 112a determines that step S204 is “included” because Nagoya City in Aichi Prefecture in (a) matches Nagoya City in Aichi Prefecture in (b).

  In step S208 of FIG. 11, the evaluation unit 112a of the server 10a determines whether it is determined as “included” as a result of step S204. When it is determined that it is included (step S206: YES), the evaluation unit 112a updates the regional information once stored in the post information table 144a in the post evaluation process (FIG. 6), and sets the value of the local classification to “Y”. And On the other hand, when it is determined not to be included (step S206: NO), the evaluation unit 112a updates the regional information temporarily stored in the post information table 144a in the post evaluation process (FIG. 6), and sets the value of the local classification. “N”. Thereafter, the evaluation unit 112a ends the process.

B-3-2. User evaluation process B:
FIG. 13 is a flowchart showing the procedure of the user evaluation process B.

  In step S <b> 222, the evaluation unit 112 a of the server 10 a receives “support” of the area information transmitted from the mobile terminal 20. For example, when a user of a mobile terminal 20 browses an evaluation (regional information) of a restaurant that can be viewed from the service providing unit 113 and agrees to the content of the regional information, There is a case where I actually had the impression that I could actually visit a restaurant. In such a case, for example, a support may be transmitted from the mobile terminal 20 to the server 10a when the user of the mobile terminal 20 presses a button displayed in association with the area information. In addition, for example, support may be automatically transmitted from the mobile terminal 20 to the server 10a for the area information referred to by the user of the mobile terminal 20. This is preferable in that an explicit operation by the user of the mobile terminal 20 is not required.

  In step S224, the evaluation unit 112a of the server 10a refers to the value of the local classification in the posted information table 144a for the regional information for which support has been received. When the value of the local classification is “N” (step S224: N), the evaluation unit 112a ends the process. On the other hand, when the value of the local classification is “Y” (step S224: Y), the evaluation unit 112a adds support points to the contributor who has registered the area information by word of mouth (step S226). When the poster of the area information has a plurality of daily areas, the evaluation unit 112a adds support points to the daily area that matches the information (facility address) indicating the area of the area information.

  In the example of FIG. 12, when the support from another user is received for the regional information RI2, the evaluation unit 112a adds a support point to the user identifier User001 who is the poster of the regional information RI2. Since the contributor of the user identifier User001 has two daily areas, the evaluation unit 112a is the daily area that matches the information indicating the area of the area information RI2 (that is, the address of the Heisei cafeteria of the facility identifier S0001). Add support points for Nagoya City, Aichi Prefecture.

  In the example of FIG. 12, every time the evaluation unit 112a receives support once, one support point is added. However, the addition method is merely an example, and various modifications are possible. For example, the number of addition points may be changed according to the daily life zone or support points of the user who supports the area information.

  An example in which the number of points to be added is changed according to the daily life of the supported user will be described. For example, if both User0003 (Fig. 9), whose daily life is Kariya City, Aichi Prefecture, and User005 (Fig. 9), whose daily life is Takashima City, Shiga Prefecture, support the regional information RI2 in Fig. 12, The number of points added by support of User003 closer to the region of information RI2 (Nagoya, Aichi Prefecture) may be larger than the number of points added by support of User005. In this way, the reliability of user evaluation can be further improved.

  An example in which the number of added points is changed according to the support points of the supported users will be described. For example, if both User0002 (FIG. 9), whose support point is 0 point, and User0003 (FIG. 9), whose support point is 12 points, support the regional information RI2 of FIG. 12, collect more support. The number of points added by supporting User 0003 may be larger than the number of points added by supporting User 0002. In this way, it is possible to increase the influence of a user who has received much support from other users. In this case, for a user having a plurality of daily areas such as User0004 (FIG. 9), an average value of a plurality of support points corresponding to the plurality of daily areas may be adopted. The largest support point may be adopted.

  As described above, according to the second embodiment, the evaluation unit 112 provides a user who has provided information related to a region to which the daily sphere belongs from a third party (user of another mobile terminal 20) who has browsed the region information. Support (evaluation) can be obtained. For this reason, “persons who know the area well” themselves can be evaluated. Specifically, the evaluation unit 112a uses the support acquired from a third party to support the user identifier of the daily life table 141a and the support points given to the daily life (a combination of the user identifier and the daily life). (Area evaluation given to) is updated. For this reason, the evaluation acquired from the third party can be accumulated for every daily area of the user. In addition, the service providing unit 113 groups the daily area table 141a for each daily area and sorts the daily area table 141a in descending order of support points, and associates it with the posting information table 144a so that it can be viewed from a plurality of portable terminals 20. can do. In this way, the service providing unit 113 can provide “ranking of people who know the area well” for each area. In this way, it is possible to provide information centering on the user, not the facility. Also, the viewer can browse information from “a person who knows the area well” together with an evaluation of the person.

C. Third embodiment:
3rd Embodiment of this invention demonstrates the structure from which the content of area information differs in the evaluation system of 1st Embodiment. Below, only the part which has a different structure and operation | movement from 1st Embodiment is demonstrated. In the figure, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment described above, and detailed description thereof is omitted.

C-1. System outline:
FIG. 14 is an explanatory diagram showing a schematic configuration of an evaluation system 1000b using the evaluation apparatus as the third embodiment. A difference from the first embodiment shown in FIG. 1 is that a server 10 b is provided instead of the server 10. The server 10 b includes a CPU 110 b instead of the CPU 110 and a hard disk 140 b instead of the hard disk 140.

  The CPU 110b includes an evaluation unit 112b instead of the evaluation unit 112. The evaluation unit 112b performs a post evaluation process (FIG. 6). However, the content of the post evaluation process executed by the evaluation unit 112b is partially different from that of the first embodiment. Details will be described later.

  The hard disk 140b is different from the first embodiment in that the facility table 143 is not provided and a post information table 144b is provided instead of the post information table 144. The posting information table 144b includes a user identifier, a text, and authenticity. That is, it differs from the posted information table 144 (FIG. 5) of the first embodiment in that the facility identifier, title, and score are not provided.

C-2. Post evaluation process:
FIG. 15 is an explanatory diagram showing how the server 10b evaluates the credibility of the word of mouth (regional information) by the post evaluation process. The procedure of the post evaluation process in the third embodiment is the same as that of the first embodiment shown in FIG. 6 except for step S106.

  In step S106 of the third embodiment, the evaluation unit 112b of the server 10b compares the character string included in the regional information with the regional characteristics associated with the poster's daily address. Specifically, the character string in the text of the regional information is compared with the regional characteristics of (i) described in FIG. 6, and the character string in the text of the regional information is related to the regional characteristics of (i). It is determined whether or not. Here, “related” means including a case where it is determined as a result of a so-called fuzzy search.

  In the example of FIG. 15, (i) as a regional characteristic associated with Nagoya City, Aichi Prefecture, which is the daily sphere of the poster of the regional information, search is made for miso, hitsumabushi, kishimen, haccho miso, miso stewed udon, Moriguchizuke Is done. Further, greenhouse oranges are searched as a regional characteristic associated with Gamagori City, Aichi Prefecture, which is the daily sphere of posters of regional information. The evaluation unit 112b determines that step S106 is “relevant” because the character string “hitsubushi is the best when there is no appetite” in the text of the area information RI3 includes the iridescent of (i).

  As described above, according to the third embodiment, the evaluation unit 112b evaluates the evaluation even when the regional information is a simple sentence that is not categorized, in other words, even the regional information given as a character string. It can be carried out.

D. Fourth embodiment:
In the fourth embodiment of the present invention, a configuration for realizing an evaluation system similar to that of the first embodiment using a plurality of servers will be described. Below, only the part which has a different structure and operation | movement from 1st Embodiment is demonstrated. In the figure, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment described above, and detailed description thereof is omitted.

D-1. System outline:
FIG. 16 is an explanatory diagram showing a schematic configuration of an evaluation system 1000c as the fourth embodiment. The difference from the first embodiment shown in FIG. 1 is that a server 10 x and a server 10 y are provided instead of the server 10. The server 10x and the server 10y are provided with the functional units described in the first embodiment divided according to the functions realized by the servers. Specifically, the server 10x includes an information acquisition unit 111 and an evaluation unit 112 in the CPU 110x, and includes an everyday area table 141, an area characteristic table 142, and a facility table 143 in the hard disk 140x. In addition, the server 10y includes a service providing unit 113 in the CPU 110y, and a posting information table 144 in the hard disk 140y.

  The area information transmitted from the portable terminal 20 is received by the information acquisition unit 111 of the server 10x and evaluated by the evaluation unit 112 of the server 10x. Then, the communication unit 150x of the server 10x transmits the area information and the evaluation to the server 10y. The server 10x corresponds to an “evaluation apparatus” in the claims.

  The server 10y associates the received evaluation with the area information received from the server 10x, and stores it in the posting information table 144. Then, the service providing unit 113 of the server 10y makes it possible to browse the area information stored in the posted information table 144 from a plurality of portable terminals 20 as “evaluation of restaurants”. The server 10y corresponds to a “service device” in the claims.

  As described above, according to the evaluation system of the fourth embodiment, the server 10y (service device) can receive and accumulate regional information and its evaluation from the server 10x (evaluation device). And the server 10y can display the accumulate | stored area information and its evaluation with respect to the portable terminal 20 (client apparatus). Furthermore, according to this form of the evaluation system, the server 10x for evaluating the regional information and the server 10y for displaying the evaluated regional information can be configured as different devices.

E. Variations:
In the above embodiment, a part of the configuration realized by hardware may be replaced by software, and conversely, a part of the configuration realized by software may be replaced by hardware. Good. In addition, the following modifications are possible.

・ Modification 1:
In the above embodiment, a mobile terminal is exemplified as the client device. However, the client device and its configuration in the above embodiment are merely examples, and any aspect can be employed. For example, it is possible to employ a device other than the form terminal as the client device, omit some of the components, add additional components, or change some of the components. .

  For example, information processing devices such as a personal computer, a PDA (Personal Digital Assistants), and a game machine may be employed as the client device. Further, image input / output devices such as a television, a digital camera, a printer, a network display, and a scanner may be employed. When these devices have a current position acquisition unit, they can be processed in the same manner as in the above embodiment. In addition, when these devices do not have a current position acquisition unit, the contents of the daily life table may be pre-registered by the user, for example.

Modification 2
In the said embodiment, the structure of the server as an evaluation apparatus was shown. However, the configuration of the server in the above embodiment is merely an example, and any aspect can be adopted. For example, the deformation | transformation which abbreviate | omits a part of the component, adds a further component, or changes a part of a component is possible.

  For example, information necessary for processing such as a daily area table, an area characteristic table, a facility table, and a posting information table may be stored in a storage medium other than the hard disk. For example, it may be stored in a flash ROM, or may be stored in a removable storage medium such as a USB memory or a USB hard disk.

・ Modification 3:
In the above embodiment, the configurations of the daily zone table, the regional characteristic table, the facility table, and the posting information table have been described. However, the configuration of each table is merely an example, and any mode can be adopted. For example, it is possible to modify such that a part of the exemplified field is omitted, a further field is added, or a part of the field is changed. One table may be divided into a plurality of tables, or a plurality of tables may be integrated into one.

  For example, the user name field may be omitted from the daily life table, and a user information table for storing the user identifier, the user name, the telephone number, the mail address, and the user address in association with each other may be newly provided. In this way, one duplicate field can be reduced from the daily table.

  For example, an image uploaded by the user may be stored in association with the posting information table.

-Modification 4:
In the above embodiment, the post evaluation process (FIG. 6) has been described by taking an example of the process procedure. However, the above procedure is merely an example, and various changes can be made. Some steps may be omitted, and other steps may be added. Further, the order of the steps to be executed may be changed.

  For example, the information acquisition unit may receive the current position measured by the GPS receiver of the mobile terminal together with the area information in step S102. Then, when the received current position matches (partially matches) the area of the word-of-mouth (area information), the credibility of the area information may be evaluated more highly.

  For example, the evaluation unit evaluates the credibility “high” in step S110 when it is determined to be related in step S108, and evaluates the credibility in step S110 if it is determined that there is no relationship in step S108. It does not have to be.

  For example, the evaluation unit may evaluate the authenticity with a score in the post evaluation process. Moreover, when evaluating credibility by a score, the evaluation part may adjust the increase / decrease range of a score according to the coincidence degree in step S106. Specifically, the score to be given may be increased when the data completely match in step S106, and the score to be given may be reduced if the data partially match in step S106.

Modification 5:
In the said embodiment, the service provision part can display the regional information accumulate | stored in the contribution information table on the portable terminal which is a client apparatus with the various aspect according to needs.

For example, the service providing unit may display “Ranking of restaurants recommended by people around the current location” on the mobile terminal that is the client device. Specifically, it can be realized by the following procedure.
-A portable terminal transmits the present position acquired with the GPS receiver to the service provision part of a server.
-The service provider of the server extracts the facilities where the received current position matches the daily service area (partial match is possible), the score is high, and the credibility is high, from the daily service area table and the posted information table To do.
The service providing unit of the server transmits the extracted facility information to the mobile terminal.
In this way, only information corresponding to the current position of the user of the client device can be displayed on the client device, so that convenience for the user can be improved.

Modification 6:
In the above-described embodiment, the user evaluation process (FIGS. 11 and 13) has been described by taking an example of a process procedure. However, the above procedure is merely an example, and various changes can be made. Some steps may be omitted, and other steps may be added. Further, the order of the steps to be executed may be changed.

  For example, the post evaluation process (FIG. 6) in step S202 of the user evaluation process A (FIG. 11) may be omitted. In this case, the credibility of the regional information is not evaluated, and only the user who provided the regional information is evaluated.

  The present invention is not limited to the above-described embodiments, examples, and modifications, and can be realized with various configurations without departing from the spirit thereof. For example, the technical features in the embodiments, examples, and modifications corresponding to the technical features in each embodiment described in the summary section of the invention are to solve some or all of the above-described problems, or In order to achieve part or all of the above-described effects, replacement or combination can be performed as appropriate.
