Description

  The present invention relates to a posted information evaluation method, a posted information evaluation system, a server thereof, a client terminal, and a program thereof.

  Along with the spread of the Internet, there are many Web sites for posting and browsing word-of-mouth information on gourmets and sightseeing spots. However, there was no index to measure the reliability of the post. For this reason, the viewer cannot determine whether the contributor of the word-of-mouth information actually writes the post after going to the store or the like, and cannot determine which post should be trusted.

  In addition, services such as SNS (Social Networking Site) established for the purpose of expanding new friendships on the Web by introducing friends to each other are becoming widespread. In this service, a variety of communities, which are groups that send information sent by individuals only to related people, are increasing. There is also the problem of not knowing which information sent within this community should be trusted.

  As related arts related to these, a word-of-mouth information analysis method has been proposed in which word-of-mouth information of a large number of people is collected, the words of the same speaker are extracted from the collected words, and the extracted words are analyzed. (See Patent Document 1). There has also been proposed a word-of-mouth information analysis method and apparatus capable of analyzing word-of-mouth information in consideration of user information such as a poster name (see Patent Document 2).

In addition, there is a proposal of a method for posting and recording data such as images and texts in association with position information acquired by means such as GPS, and providing post information in the peripheral area of the current location of the viewer when the viewer accesses it. (See Patent Document 3).
Furthermore, an automatic action record creation system capable of creating a self action record such as a travel record has also been proposed (see Patent Document 4).
However, there is no system or method for evaluating posted information in association with location information.

It is not necessarily essential for the solution of the invention.

[First embodiment]
FIG. 1 is a diagram showing an outline of a system configuration which is a preferred embodiment of the present invention. FIG. 2 is a diagram showing the concept of the present invention and the outline processing flow. FIG. 3 is a diagram showing details of a processing flow in the above-described system according to a preferred embodiment of the present invention. FIG. 4 is an example of post information, attached position data, and date / time data according to the present invention. Hereinafter, the present invention will be described with reference to FIGS.

  In the embodiment of FIG. 1, the client terminals 20 a, 20 b, and 20 x receive radio waves for position detection from a plurality of GPS satellites 10. In this figure, only one GPS satellite 10 is shown, but it is necessary to receive radio waves from at least three, usually four or more GPS satellites 10, in order to specify the position, as is well known. There is. The radio wave transmitted from the GPS satellite 10 includes various orbit information and extremely accurate time data by an atomic clock. In order to obtain easy-to-handle position data such as the latitude and longitude of the current position from these pieces of information, the client terminals 20a, 20b and 20x hold additional information obtained from the orbit information of the GPS satellite 10 and perform complicated positioning calculations. It is necessary to make it. For this reason, the position data acquisition server 60 normally connected via the public communication network 40 performs these positioning calculations, and the obtained results are used as position data (latitude, longitude, altitude if possible, etc.) for the client terminal 20a. , 20b, and 20x are used. In addition, positioning calculation can also be performed in the client terminals 20a, 20b, and 20x.

  The client terminals 20a, 20b, and 20x transmit their position data such as latitude and longitude, date / time data, and posted information to the database server 80. The client terminal may be a mobile phone as shown in 20a as shown in FIG. 1, or a laptop computer equipped with a GPS function as shown in 20b. The client terminals 20a, 20b, and 20x include a position data acquisition unit that can acquire position data, a time measurement unit that can acquire date and time data from which the position data was acquired, and a storage unit that stores the position data and date and time data And a transmission unit that attaches and transmits the post information, the position data acquired or stored, and the date / time data when posting the post information. These specific configurations will be described later in detail with reference to FIG.

  The web server 70 and the database server 80 are connected via a network 50. Each of these servers includes a receiving unit that receives its own position data, date / time data, and post information, and a reliability evaluation unit that evaluates reliability based on the received position data and date / time data attached thereto. Is provided. Note that the database server 80 described above may be a single server or a plurality of servers, or may be included in the Web server 70. Specific examples of the hardware of the Web server 70 and the database server 80 will be described later in detail with reference to FIG.

  The posted information and the evaluation by the reliability evaluation unit are attached and stored in the storage unit of the database server 80. The Web server 70 and the database server 80 are connected to the information terminals 90a, 90b, and 90x via the network 50 and, if necessary, the public communication network 40. The information terminals 90a, 90b, and 90x may be used by critics such as gourmet sites, and may be used by ordinary people. In addition, there is a case where a contributor of the posting information sees. The information terminals 90a, 90b, and 90x may be personal computers, portable notebook computers, or mobile phones. It can also be shared with the client terminals 20a, 20b, 20x.

  FIG. 2 is a diagram showing an outline of the concept of the present invention and its processing flow. As shown in FIG. 2, various postings of so-called word-of-mouth information are made for ABC restaurants, for example. The post data is posted with the position data of the client terminal 20x (hereinafter referred to as 20x representative of the client terminals 20a, 20b, and 20x) and the date and time data at which the position data is acquired. When posting, position information is acquired by the position data acquisition server 60. These pieces of information are transmitted to the database server 80. The database server 80 includes a reliability evaluation unit that evaluates reliability based on position data and date / time data received with post information attached thereto, and evaluates the reliability of post information. In the example of FIG. 2, the position data attached to the posted information is compared with the true position data of the ABC restaurant. As a result of the comparison, it is evaluated that the reliability of the post information of “slow” and “not good” when the position data difference is large is low (20b). On the other hand, post information “delicious” within a certain range of position data is evaluated as having high reliability (20a). The reason why the difference in the position data is within a certain range is that it varies depending on the error of the position data acquisition unit and the facility such as the restaurant. The posted information and the evaluation content are stored in the database server 80.

  When a person interested in the ABC restaurant makes an inquiry to the Web server 70, the Web server 70 retrieves information related to the ABC restaurant from the database server 80 and returns it to the information terminal 90x. Therefore, those who are interested in ABC restaurant look at each post information, the reliability of the “delicious” information is high, and the reliability of the post information of “slow” and “not good” is low, so the reliability is high The post information of “It was delicious” can be used to critique gourmet sites such as “Recommend ABC Restaurant”.

  FIG. 3 is a diagram showing details of a processing flow in the above-described system according to a preferred embodiment of the present invention. First, the client terminal 20x transmits a positioning information request (position data request) to the position data acquisition server 60 periodically or by a user operation. This positioning information request includes GPS satellite information ("Almanac" which is rough orbit information of all GPS satellites and "Ephemeris" which is accurate orbit information of the GPS satellite itself) in this positioning information request Information on peripheral reference stations (stations serving as a reference among peripheral base stations) may be included.

  The position data acquisition server 60 performs a positioning calculation based on the received information (step S10), and returns a positioning result (data such as longitude, latitude, altitude, reliability, etc. can also be acquired). Alternatively, although not illustrated, the position data acquisition server 60 does not perform the positioning calculation, and the client terminal 20x facilitates the positioning calculation using information from the nearest base station in order to facilitate the positioning calculation. “Assist data” may be transmitted to the client terminal 20x, and the positioning calculation may be performed by the client terminal 20x.

  The client terminal 20x generates the client position data obtained in this way (step S11), and transmits it to the database server 80 attached to the posting information. At this time, it is desirable to send the date and time data obtained by acquiring the position data as well. This is because it is useful for more reliable evaluation.

  The database server 80 receives these transmitted data and performs reliability evaluation based on these data (S12). After the reliability evaluation, the reliability evaluation is stored together with the posted information (S13). Hereinafter, a specific example of reliability evaluation will be described.

  FIG. 4 is an example of post information, attached position data, and date / time data according to the present invention. As shown in FIG. The content of one post information is “delicious”, the target is an ABC restaurant, the attached position data is latitude X1 and longitude Y1, and the date and time is from April 22, 2006 PM 6:30 to PM 8:30 is there. Here, it is assumed that the true position data of the ABC restaurant is latitude XR1 and longitude YR1. Further, it is assumed that the business hours of the ABC restaurant are from 10 am to 10 pm. No. The reliability evaluation of one posting information is the true position data of the ABC restaurant stored in advance in the database server 80 (or newly acquired if not stored), with the latitude X1 and longitude Y1 of the attached position data. This is done by calculating the distance between latitude XR1 and longitude YR1. If the calculated distance is equal to or less than a predetermined value, the reliability is evaluated as “high”. Furthermore, the start time and end time are compared with the business hours of the ABC restaurant. Furthermore, the time required for the service provided by the ABC restaurant is also an object of evaluation. No. In the attached date and time data of 1 post information, since it takes 2 hours from the start to the end, there is a high possibility of having eaten at the ABC restaurant. Therefore, there is a rational that such information is highly reliable.

  On the other hand, no. 2 The position data of the position information attached to “slow” of the posted information is latitude X2 and longitude Y2, and the date and time is from April 23, 2006 AM11: 30 to AM11: 35. When the distance between the latitude XR1 and the longitude YR1 which is the true position data of the ABC restaurant is calculated, the calculated distance is more than a predetermined value and is considerably far away. Furthermore, when the start time and end time are compared with the business hours of the ABC restaurant, they are within business hours. However, it is impossible to eat ABC restaurant food in 5 minutes. Therefore, the reliability is evaluated as “low”.

  No. The position data of the position information attached to “Imaichi” of the 3 post information is latitude X3 and longitude Y3, and the date and time is from April 24, 2006 PM11: 30 to PM11: 50. When the distance between the latitude XR1 and the longitude YR1 which is the true position data of the ABC restaurant is calculated, the calculated distance is more than a predetermined value and is considerably far away. Furthermore, when the start time and end time are compared with the business hours of the ABC restaurant, they are out of business hours. Therefore, it is thought that he posted “Imaichi”, which is a bad evaluation because he called late at night and tried to eat at the ABC restaurant but did not answer. Therefore, the reliability is evaluated as “low”.

  In this way, the posted information is stored in the database server 80 with a reliability evaluation (S13). When a search for posted information about the ABC restaurant is performed from the information terminal 90x via the Web server 70, the database server 80 performs a search (S14). When a search is performed, No. 1 to No. Post information up to 3 is retrieved and transmitted via the Web server 70. From the sent post information, it can be seen from the reliability evaluation that only the post information “delicious” can be trusted, and the ABC restaurant is recommended.

[Second Embodiment]
The second embodiment relates to a posting information evaluation system that makes posting information and map data easy to use for the user. FIG. 5 is a diagram showing an example displayed by the posted information evaluation system of the present invention.

Can do.

  As shown in FIG. 5, when an ABC restaurant is searched from the information terminal 90x, a map near the ABC restaurant stored in the map data storage means is searched by the map search means based on the true position data. The retrieved map data is transmitted to the information terminal 90x by the Web server 70. The transmitted map of the vicinity and the icon representing the posted information on the map are displayed by the display means of the information terminal 90x. In FIG. 5, the icon is displayed as a black dot on a circle. For example, when the ABC restaurant icon is clicked, the posted information described in the first embodiment is displayed in a state where the reliability is evaluated. Therefore, the user can obtain highly reliable information about the ABC restaurant.

  In addition, facilities other than the ABC restaurant are also displayed with icons on the map. Therefore, for example, if the ABC restaurant is not suitable, it is possible to know the post information in a state where the reliability is evaluated by clicking on the icon of whether another KGB bar is good. Furthermore, it is possible to know what post information is in the XYZ bar in a state where the reliability is evaluated. Therefore, it is convenient to know what kind of shops are nearby and their reputation is highly reliable.

  Furthermore, the user can narrow down by the specific condition input by the specific condition input means and appropriately input by the narrowing means. In the example of FIG. 5, the display range of icons indicating that there is a facility and post information is narrowed under the condition of a circled range surrounded by a dotted line. This narrowing down can also be performed by date, season or keyword.

[Third embodiment]
In the third embodiment, the client terminal 20x can acquire the position data log, and transmits the position data log, related posting information, and user information to be posted. This can be realized by providing a location data log unit in place of the location data acquisition unit of the client terminal 20x in the first embodiment. Instead of providing the location data log unit in the client terminal 20x, the location data may be transmitted to the database server 80 at certain time intervals.

  FIG. 6 shows an example of post information, attached position data, and date / time data when post information is transmitted with the position data log of the present invention. FIG. 7 shows an example of user information to be posted. As shown in FIG. 6, for example, information about restaurants visited based on the location data log for about one week can be posted together. In this case, the contents are simple in the example of FIG. 6, but if it is desired to convey the details, the position data log can be transferred to a personal computer or the like, and the personal computer can be used as the information terminal 90x. In addition, the location data log acquired by the client terminal 20x may be transmitted to the database server 80, the location data log stored in the database server 80 may be read later by the client terminal 20x, and post information may be added and transmitted. it can. Regarding the evaluation of the reliability, since the user information shown in FIG. 7 is added in addition to the contents described in the first embodiment, the reliability of the evaluation of the posted information is further increased.

[Fourth embodiment]
In the fourth embodiment, when posting information is posted with user information added in the third embodiment, it is determined whether or not the poster is a community participant, and the same community as the poster Disclose post information only to other community participants.

  Therefore, in the database server 80 of the posted information evaluation system in FIG. 1, a participant storage unit that stores data of each community participant, and a determination unit that determines whether the poster of the posted information is a community participant. And authorizing means for permitting disclosure of posted information when the poster is determined to be a community participant and the accessor is a community participant of the same community as the poster. Participant storage means, determination means, and permission means can be realized by installing related software programs using related hardware of the server shown in FIG.

  When the user information as shown in FIG. 7 is provided, the participating community is a middle-aged man, so only information suitable for the middle-aged man as shown in FIG. 8 is disclosed. As described above, since only the information suitable for the community is provided, it is possible to solve the problem that the post information suitable for the user must be found out from the overflow of unnecessary information.
