  The system control unit 54 includes a CPU (Central Processing Unit) 54a, a ROM (Read Only Memory) 54b, a RAM (Random Access Memory) 54c, and the like. FIG. 3B is a diagram illustrating an example of functional blocks in the system control unit 54. The system control unit 54 as a computer executes position analysis processing according to the position analysis processing program stored in the storage unit 52. In such processing, the system control unit 54 functions as a post data acquisition unit 541, a location information acquisition unit 542, a terminal presence / absence determination unit 543, a location information output unit 544, and the like, as shown in FIG. To do. The post data acquisition unit 541 is an example of a first acquisition unit in the present invention. The position information acquisition unit 542 is an example of a second acquisition unit in the present invention. The terminal presence / absence determination unit 543 is an example of a determination unit in the present invention. The position information output unit 544 is an example of output means in the present invention.

  The post data acquisition unit 541 acquires post data transmitted from the mobile terminal 1 via the mobile communication network MN and information associated therewith from the post management database 522. The post data acquired by the post data acquisition unit 541 includes post data transmitted from the mobile terminal 1 via the mobile communication network MN using the mobile terminal 1 as a transmission source. The post data acquired by the post data acquisition unit 541 does not include post data transmitted from a personal computer without passing through the mobile communication network MN, for example.

  The position information acquisition unit 542 acquires position information (that is, position information indicating the position of the spot) corresponding to the keyword included in the post data acquired by the post data acquisition unit 541 from the keyword association database 521, for example. When the keyword association database 521 is provided in another server different from the position analysis processing server 5, the position information acquisition unit 542 includes a search query including a keyword included in the post data acquired by the post data acquisition unit 541. Is transmitted to the other server, and the position information corresponding to the keyword included in the posted data is acquired from the other server. The position information acquisition unit 542 can acquire position information indicating the position of the spot that the portable terminal 1 that has transmitted the posted data would have existed at the time of transmission of the posted data. However, at this stage, there may be a case where the portable terminal 1 that is the transmission source of the posted data does not exist at the spot position or in the vicinity of the position. Therefore, in order to support the presence of the post data transmission source mobile terminal 1 at or near the position of the spot at the time of transmission of the post data with a certain degree of accuracy, the presence or absence of the terminal A determination unit 543 is provided.

  The terminal presence / absence determination unit 543 contributes to the determination of the position where the transmission source mobile terminal 1 was present when the post data acquired by the post data acquisition unit 541 was transmitted. Based on the information, within the range (hereinafter referred to as “neighboring range”) in which the mobile terminal 1 that is the transmission source at the time of transmission of the posted data is in the vicinity of the position corresponding to the position information acquired by the position information acquisition unit 542 Determine if it existed. Here, the “related information” includes, for example, “image data added to post data”, “position information added to post data”, “poster is in a spot corresponding to the position information” "Word or phrase expressed on the premise of", "word or phrase expressed on the assumption that the poster is not in a spot at a position corresponding to the position information", and "of the mobile terminal 1 of the post data transmission source “Reservation history that can be acquired using the user ID of the user as a key” or the like. For example, “exists within a range near the position corresponding to the position information” includes, for example, “exists within a predetermined distance range (for example, 1 to 2 m) from the position corresponding to the position information”, “position corresponding to the position information” “Exist in a predetermined area (for example, a predetermined address)” and “exist in a range movable within a predetermined time (for example, several tens of seconds) from the position corresponding to the position information”. Based on the determination of “whether or not it was within the vicinity range of the position corresponding to the position information”, the position of the spot corresponding to the keyword included in the posted data or the position of the spot corresponding to the keyword included in the posted data by the transmission source mobile terminal 1 This is to determine whether or not there is a high possibility that the user was present in the vicinity of the position. The terminal presence / absence determination unit 543 determines whether or not the portable terminal 1 that is the transmission source of the posted data related to the spot exists at or near the position of the spot at the time of transmission. Using information, it can be specified with a certain degree of accuracy. Details of a method for determining whether or not the mobile terminal 1 is present based on the related information will be described later.

If the terminal presence / absence determination unit 543 determines that the location information output unit 544 is within the predetermined range, the location information output unit 544 uses the post data acquisition unit 541 to acquire the location information acquired by the location information acquisition unit 542. It is output as information indicating a position where the data can be connected to the mobile communication network MN. Examples of the location information output destination by the location information output unit 544 include a location management database 524, another server, an administrator's terminal, or a portable storage medium. The information output by the position information output unit 544 includes not only the position information acquired by the position information acquisition unit 542 but also the mobile communication network MN through which the posted data acquired by the posted data acquisition unit 541 has passed. You may comprise so that the information which shows the communication carrier to manage may be included. Further, the information output by the position information output unit 544 is configured to include the post data acquired by the post data acquisition unit 541 and the user ID of the user of the mobile terminal 1 that is the transmission source of the post data. May be.
[2. Operation of information providing system S]

  Next, operation | movement of the information provision system S which concerns on this embodiment is demonstrated using FIG. FIG. 5 is a flowchart showing the position analysis processing in the system control unit 54 of the position analysis processing server 5. As a premise of the operation described below, it is assumed that post data acquired from the post management database 31 of the post processing server 3 is registered in the post management database 522. In addition, it is assumed that the reservation history acquired from the reservation management database 41 of the reservation processing server 4 is registered in the reservation management database 523.

  The process shown in FIG. 5 is executed, for example, at a preset time interval (for example, every 24 hours). When the process shown in FIG. 5 is started, the posted data acquisition unit 541 transmits the mobile terminal 1 from the posted data registered in the posted management database 522 and not associated with the processed flag. The posting data transmitted through the mobile communication network MN as a source is selected (step S1). For example, the posting data acquisition unit 541 uses the mobile terminal 1 as a transmission source by a user agent (a character string indicating a communication carrier) or a transmission source IP address associated with the posting data registered in the posting management database 522. Posting data transmitted via the communication network MN is selected.

  By the way, in the case of post data transmitted by the mobile router via the mobile communication network MN, the user agent may not be included in the header of the request, so that selection by the user agent may be difficult. Or even if the user agent is included in the header of the request, it is transmitted via the mobile communication network MN with the mobile terminal 1 as the transmission source because the communication carrier cannot be identified from the information in the user agent. It is also assumed that it is difficult to select post data. Therefore, in such a case, for example, it is more preferable to select the posted data based on the transmission source IP address associated with the posted data. When the communication carrier can be specified from the network part of the transmission source IP address (indicating the network to which the host belongs), the posted data can be selected by the transmission source IP address. In this case, for example, since the mobile communication network MN is shown as the network to which the gateway server 2 that relays the posted data belongs in the network part of the transmission source IP address, the posted data is selected by this. be able to. Further, when the posted data passes through the mobile communication network MN, the transmission source IP address is, for example, the IP address of the gateway server 2. Therefore, if the IP address list of the gateway server 2 is stored in the storage unit 52 in advance, the posting data acquisition unit 541 can select the posting data based on the transmission source IP address by referring to the list. .

  The post data acquisition unit 541 selects post data transmitted from the mobile terminal 1 via the mobile communication network MN when acquiring post data from the post management database 31 of the post processing server 3. Then, it may be configured to be registered in the post management database 522. In this case, it is not necessary to select post data in step S1.

  Next, the posting data acquisition unit 541 acquires, for example, the posting data selected in step S1 and information associated with the posting data from the posting management database 522 (step S2). Thereby, for example, a plurality of post data is acquired. Next, the position information acquisition unit 542 specifies one piece of post data from the post data acquired in step S2 (step S3). Next, the position information acquisition unit 542 acquires position information corresponding to the keyword included in the post data specified in step S3 from, for example, the keyword association database 521 (step S4). For example, it is assumed that “AA hotel” and “lobby” are included in the post data specified in step S3, and the keyword association database 521 shown in FIG. In this case, the keywords “AA hotel” and “lobby” are extracted from the post data specified in step S3 by, for example, morphological analysis, and the extracted keywords “AA hotel” and “lobby” (a set of keywords). The position information (position information indicating the position of the spot) “Nagoya City XX Ward 1-2, AA Hotel, 1st floor” associated with the keyword that matches the keyword is the keyword association database shown in FIG. 521.

  Next, the terminal presence / absence determination unit 543 executes terminal presence / absence determination processing (step S5). In the terminal presence / absence determination process, the terminal presence / absence determination unit 543 determines the posting based on the related information that contributes to the determination of the position where the transmission source mobile terminal 1 was present when the post data specified in step S3 was transmitted. It is determined whether or not the transmission source mobile terminal 1 was present in the vicinity of the position corresponding to the position information acquired in step S4 at the time of data transmission.

  6 to 8 are flowcharts showing specific examples of the terminal presence / absence determination processing in step S5.

  First, the terminal presence / absence determination process shown in FIG. 6 will be described. In the process shown in FIG. 6, first, the terminal presence / absence determination unit 543 determines whether image data is associated with the post data specified in step S3 (step S51). For example, when the image data is registered in the posting management database 31 in association with the posting data specified in step S3, it is determined that the image data is associated with the posting data. Since this image data is image data transmitted by being added to the post data, it is hereinafter referred to as “added image data”. If the terminal presence / absence determination unit 543 determines that the image data is associated with the post data specified in step S3 (step S51: YES), the process proceeds to step S52. On the other hand, if the terminal presence / absence determination unit 543 determines that the image data is not associated with the post data specified in step S3 (step S51: NO), the terminal presence / absence determination unit 543 determines that it is “not in the vicinity” (step S51). S58), the process returns to the process shown in FIG. Alternatively, in this case, the process may be shifted to any one of the processes in FIGS. 7, 8A, and 8B.

  In step S52, the terminal presence / absence determination unit 543 acquires the image shooting date and time from the added image data, and acquires the transmission date and time of the posted data from the posted data specified in step S3. Next, the terminal presence / absence determination unit 543 determines, based on the image capturing date / time and the transmission date / time acquired in step S52, between the time of image capturing of the added image data and the time of transmitting post data specified in step S3. It is determined whether or not the time difference is equal to or less than a predetermined value (for example, several tens of seconds) (step S53). If the terminal presence / absence determination unit 543 determines that the time difference between the time when the added image data is captured and the time when the post data specified in step S3 is transmitted is not less than a predetermined value (step S53: NO), “not in the vicinity range” is determined (step S58), and the process returns to the process shown in FIG.

  On the other hand, the terminal presence / absence determination unit 543 determines that the time difference between the time when the added image data is captured and the time when the post data specified in step S3 is transmitted is equal to or smaller than a predetermined value (step S53). : YES), the process proceeds to step S54. In step S53, when the condition that the time difference between the time when the added image data is captured and the time when the posted data specified in step S3 is transmitted is equal to or smaller than a predetermined value, the user of the portable terminal 1 However, it can be estimated that there is a possibility that the posted data is immediately transmitted from the portable terminal 1 without moving so much by taking a photographic image. Therefore, in this case, it is highly likely that the transmission source portable terminal 1 was present in the vicinity of the position corresponding to the position information acquired in step S4 when the post data specified in step S3 was transmitted. Since it can be determined, it may be determined that “it is in the vicinity range” and the process returns to the process illustrated in FIG. 5. However, in order to increase the accuracy of being in the vicinity range, it is more desirable to proceed to step S54.

  In step S54, the terminal presence / absence determination unit 543 determines whether or not the position information of the image shooting point is added to the added image data as, for example, a geotag. If the terminal presence / absence determination unit 543 determines that the position information of the image shooting point is added to the added image data (step S54: YES), the process proceeds to step S55. The position information added to the image data is hereinafter referred to as “image data position information”. On the other hand, if the terminal presence / absence determination unit 543 determines that the position information of the image capturing point is not added to the added image data (step S54: NO), the process proceeds to step S56.

  In step S55, the terminal presence / absence determination unit 543 determines that the position indicated by the position information acquired in step S4 and the position indicated by the position information of the added image data (that is, the image shooting point) are in the vicinity. It is determined whether or not a predetermined condition is satisfied. The predetermined condition includes, for example, the position indicated by the position information acquired in step S4 (for example, an address or a plane position specified by latitude and longitude) and the position indicated by the position information of the added image data (latitude and latitude). The condition that the distance to the plane position specified by the longitude is within a predetermined distance is applicable. Alternatively, the predetermined condition corresponds to a condition that the position indicated by the position information acquired in step S4 and the position indicated by the position information of the added image data are both within the predetermined area. If the terminal presence / absence determination unit 543 determines that the predetermined condition is not satisfied (step S55: NO), the terminal presence / absence determination unit 543 determines that the terminal is not in the vicinity range (step S58) and returns to the process illustrated in FIG. On the other hand, if the terminal presence / absence determining unit 543 determines that the predetermined condition is satisfied (step S55: YES), the terminal presence / absence determining unit 543 determines “being in the vicinity range” (step S59) and returns to the process illustrated in FIG.

  In step S56, the terminal presence / absence determination unit 543 displays a word or phrase indicating that the image of the added image data is taken at a spot corresponding to the keyword included in the post data specified in step S3. Is included in the posted data. A phrase means, for example, a group of words that make one meaning. Each word and phrase is a component of a sentence. Hereinafter, the spot corresponding to the keyword included in the posted data is referred to as a “specific spot”. An example of a phrase indicating that the photograph was taken at a specific spot is “I photographed at AA Hotel”. Here, the phrase “photographed in” is configured to be registered in, for example, a word list stored in advance in the storage unit 52, and the terminal presence / absence determination unit 543 is referred to at the time of determination in step S56. Configure. When the terminal presence / absence determination unit 543 determines that the word or phrase indicating that the image is taken at the specific spot is not included in the post data specified in step S3 (step S56: NO), Proceed to step S57. On the other hand, if the terminal presence / absence determination unit 543 determines that the post data specified in step S3 includes a word or phrase indicating that the terminal was photographed at the specific spot (step S56: YES), “ It is determined that it is within the vicinity range (step S59), and the process returns to the process shown in FIG.

  In step S57, the terminal presence / absence determination unit 543 determines whether or not the subject extracted from the added image data is a predetermined standard subject that can be photographed at a specific spot. Here, the subject from the image data is extracted by, for example, a known image recognition technique. Then, feature extraction of the extracted subject is performed, and a feature amount is obtained. If the difference between the feature amount thus obtained and the feature amount of the standard subject set in advance in association with the keyword is within the threshold, the subject extracted from the added image data is a predetermined standard. The subject is determined. When it is determined that the subject extracted from the added image data is not a predetermined standard subject (step S57: NO), the terminal presence / absence determination unit 543 determines that the subject is not in the vicinity range (step S58). Returning to the process shown in FIG. On the other hand, if the terminal presence / absence determination unit 543 determines that the subject extracted from the added image data is a predetermined standard subject (step S57: YES), the terminal presence / absence determination unit 543 determines that the subject is within the vicinity range. (Step S59), the process returns to the process shown in FIG.

  In step S54, when the position information of the image shooting point is not added to the added image data, the process of step S57 may be performed with priority over the process of step S56. In this case, the process of step S56 is configured to be performed when it is determined that the subject extracted from the added image data is not a predetermined standard subject. Further, even in the case where the position information of the image shooting point is added to the added image data in step S54, the process of step S56 or the process of step S57 is performed with priority over the process of step S55. You may comprise.

  Next, the terminal presence / absence determination process shown in FIG. 7 will be described. In the process shown in FIG. 7, first, the terminal presence / absence determination unit 543 determines whether or not a user ID is associated with the post data specified in step S3 (step S61).

  In step S62, the terminal presence / absence determination unit 543 posts a reservation history (that is, posting posted data) from the reservation management database 523 corresponding to the user ID of the user of the mobile terminal 1 that is the transmission source of the posted data specified in step S3. Reservation history by the user who has made a request). Next, the terminal presence / absence determination unit 543 determines that the user of the mobile terminal 1 that is the transmission source of the posted data specified in step S3 “a day including the time of transmission of the posted data as a usage date from a specific spot (for example, , History of making reservations at facilities within 10-20 m), or “within a predetermined range (for example, 10-20 m) from a specific spot with the day before or the day including the time of transmission of the posted data as the accommodation date. It is determined whether or not “history of use reservation or accommodation reservation in facility” is included in the reservation history acquired in step S62 (step S63). Here, whether or not the facility indicated by the reservation history is within a predetermined range from the specific spot is determined by the positional information indicating the position of the specific spot and the location of the facility indicated by the reservation history (for example, address or latitude) And position information indicating the longitude). If the terminal presence / absence determining unit 543 determines that the reservation history does not include the history of use reservation or accommodation reservation in the facility within the predetermined range from the specific spot (step S63: NO), “not in the vicinity range” "(Step S66), and the process returns to the process shown in FIG.

  On the other hand, if the terminal presence / absence determination unit 543 determines that the reservation history includes a history of making a use reservation or an accommodation reservation in a facility within a predetermined range from the specific spot (step S63: YES), the process proceeds to step S64. In step S63, when the condition that the reservation history includes a history of making a reservation for use or accommodation in a facility within a predetermined range from the specific spot, the transmission source mobile terminal 1 transmits the posted data at step S4. Since it can be determined that there was a possibility that it was in the vicinity range of the position corresponding to the position information acquired in step S5, it is determined that “it is in the vicinity range” and the process returns to the processing shown in FIG. May be. However, in order to increase the accuracy of being in the vicinity range, it is more desirable to proceed to step S64.

  In step S64, the terminal presence / absence determination unit 543 determines whether or not the fee corresponding to the use reservation or the accommodation reservation of the facility within the predetermined range from the specific spot has been settled based on the reservation history acquired in step S62. Determine. If the terminal presence / absence determination unit 543 determines that the charge corresponding to the use reservation or accommodation reservation of the facility within the predetermined range from the specific spot has not been settled (step S64: NO), the process proceeds to step S65. On the other hand, if the terminal presence / absence determination unit 543 determines that the charge corresponding to the use reservation or accommodation reservation of the facility within the predetermined range from the specific spot has been settled (step S64: YES), “in the vicinity range” "Yes" (step S67), the process returns to the process shown in FIG.

  In step S65, the terminal presence / absence determination unit 543 determines, based on the reservation history acquired in step S62, whether the use reservation for the facility within the predetermined range from the specific spot or the cancellation of the accommodation reservation has been cancelled. If the terminal presence / absence determination unit 543 determines that the use reservation or the accommodation reservation within the predetermined range from the specific spot has not been canceled (step S65: NO), the terminal presence / absence determination unit 543 determines that the facility is within the vicinity range. Then, the process returns to the process shown in FIG. On the other hand, if the terminal presence / absence determination unit 543 determines that the use reservation of the facility within the predetermined range from the specific spot or the cancellation of the accommodation reservation has been made (step S65: YES), it determines that it is “not in the vicinity range”. (Step S66), the process returns to the process shown in FIG.

  In step S63, when the history of making a reservation for use or accommodation in a facility within a predetermined range from the specific spot is included in the reservation history, the process of step S65 is performed with priority over the process of step S64. It may be configured. In this case, the process of step S64 is configured to be performed, for example, when it is determined that the use reservation or the accommodation reservation within the predetermined range from the specific spot has not been canceled.

  Next, the terminal presence / absence determination process shown in FIG.

It is determined whether or not a word or phrase expressed on the premise that the post data is included in the post data (step S71). Here, words or phrases expressed on the premise of being in a specific spot (hereinafter collectively referred to as “affirmative words”) include, for example, “now,” “now, is” (“to” is particularly Non-limiting words or phrases), “present”, “now”, and the like. If it is such an affirmative word, it can be considered that there is a high possibility of posting from the front of the specific spot. Note that words or phrases included in the first half and the second half of the sentence may correspond to each other. For example, “Now,” the first half of a sentence such as “I am now in front of” and “I am in front of” the second half of a sentence are positive words configured to respond. On the other hand, for example, if only “Now” is an affirmative word, expressions that do not assume that you are in a specific spot, such as “Today is ~” or “Imabari is beautiful” are included, so punctuation marks, commas, It is good to compose a positive word including a period. Such an affirmative word is configured to be registered in, for example, an affirmative word list stored in advance in the storage unit 52, and the terminal presence / absence determination unit 543 is configured to refer to the determination in step S71. Alternatively, a blacklist for registering an excluded word or phrase such as “today” or “Imabari” is stored in advance in the storage unit 52, for example, and the word or phrase included in the blacklist is specified in step S3. If included in the data, a negative (NO) determination may be made in step S71.

  If the terminal presence / absence determination unit 543 determines that the positive word is included in the posted data specified in step S3 (step S71: YES), the process proceeds to step S72. In this case, the configuration may be such that it is determined that “it is in the vicinity range” (step S74) and the processing returns to the processing shown in FIG. However, in order to increase the accuracy of being in the vicinity range, it is more desirable to proceed to step S72. On the other hand, if the terminal presence / absence determination unit 543 determines that the positive word is not included in the posted data specified in step S3 (step S71: NO), the terminal presence / absence determination unit 543 determines that the word is not in the vicinity range (step S71). S73), the process returns to the process shown in FIG. Alternatively, in this case, the process may be shifted to any one of the processes in FIGS. 6, 7 and 8B.
