1 (4). Area Presentation Operation The area presentation operation of this embodiment will be described below. The area presentation operation includes an area extraction operation, an index operation, a posted information analysis operation, a posted information storage operation, and a data presentation operation.

1 (4) -1. Area extraction operation (congestion index acquisition operation)
FIG. 5 is a flowchart showing the area extraction operation of the present embodiment. The population estimation unit 100 of the congestion analysis server AS acquires the location information L of the mobile terminal user from the location information server LS (S1010). FIG. 6 shows an example of a specific configuration of the position information L provided from the position information server LS. The position information L includes a plurality of entries indicating the position (latitude and longitude) of the mobile terminal at a certain time. Each entry indicates a “user ID” field indicating a user identifier of the mobile terminal, a “latitude” field indicating the latitude of the mobile terminal, a “longitude” field indicating the longitude of the mobile terminal, and a time when the mobile terminal performed positioning. It has a “positioning time” field.

  The population estimation unit 100 calculates an estimated population for each area A and each time zone based on the position information L (S1020). In this step, any estimation method can be adopted. For example, the estimated population is calculated by multiplying the number of users actually existing in the area A by the reciprocal of the proportion of the users of the carrier in the total population. Is possible.

  In the present embodiment, area A is a mesh-like region (mesh) divided based on latitude and longitude. The mesh described above may be a standard area mesh (for example, a quarter area mesh) provided by the Statistics Bureau of the Ministry of Internal Affairs and Communications in Japan, or may be a mesh defined by another method.

  FIG. 7 is an example of the estimated population table 140 in which the estimated population calculated by the population estimation unit 100 is stored. Each entry of the estimated population table 140 includes a “time zone” field and a “mesh code” field indicating the calculation target of the estimated population, a “estimated population” field indicating the calculated estimated population value, and a prefecture where the mesh code is included. It includes a “State” field that indicates.

  In the estimated population table 140 of FIG. 7, 1 hour is adopted as the time width of each time zone, but it is naturally understood that any time length can be adopted. Further, if the mesh code of a certain mesh (area A) is determined, the prefecture to which the mesh belongs can be determined, so the “prefecture” field in the estimated population table 140 is not an essential information item. If the mesh corresponding to one mesh code spans two or more prefectures, the prefecture showing the widest area in the mesh may be the prefecture corresponding to the mesh code. The prefecture where the predetermined point (for example, the center point) belongs may be the prefecture corresponding to the mesh code.

  The arrangement processing unit 110 arranges the estimated population for each area A (mesh code) (S1030). That is, the array processing unit 110 stores estimated population values included in a plurality of entries having the same mesh code in one array (a data structure that can include a plurality of data of the same type). Then, one entry including an “estimated population array” field indicating the stored array is created and stored in the array table 150. By reducing the number of entries by the above array processing, the calculation load of the subsequent processing is reduced. In order to further reduce the calculation load, only the area A in which the estimated population exceeds a predetermined threshold may be set as the target of the above arraying process.

  As shown in FIG. 8, in addition to the “estimated population array” field, each entry in the array table 150 includes a “mesh code” field, a “prefecture” field, and a time zone corresponding to the first element of the array. A “start time” field indicating the start time and a “time width” field indicating the time width of each time zone are included.

  The season adjustment unit 120 performs a season adjustment process for each entry included in the arrangement table 150 (S1040). Seasonal adjustment processing is processing that removes the influence of periodic components (seasonal variation) from time-series data (original series). In this step, any seasonal adjustment method can be adopted. For example, the seasonal adjustment unit 120 calculates a seasonal variation pattern by calculating a seasonal variation pattern from the original series of a certain period in the past for each mesh code, and adjusts the estimated population in the “estimated population array” field based on the seasonal index. . The seasonal index can be obtained by an arbitrary method such as a moving average method or a linkage ratio method.

  FIG. 9 is an example of the adjusted population table 160 in which the estimated population adjusted for the season is stored. Each entry in the adjusted population table 160 includes a “mesh code” field, a “prefecture” field, a “time zone” field indicating the calculation target of the adjusted estimated population, an “estimated population” field before the seasonal adjustment, The “estimated population after adjustment” field that has undergone seasonal adjustment processing, the “standard deviation” field that indicates the standard deviation of the estimated population after seasonal adjustment processing, and the average of the estimated population over a relatively long period (for example, one month) A “long term moving average” field indicating the The period for which the standard deviation is calculated is a relatively long period comparable to the long-term moving average.

  As can be understood from FIG. 9, each entry in the adjusted population table 160 is specified by a combination of a mesh code and a time zone. In the arrangement table 150 (FIG. 8) described above, one entry includes a plurality of time zones, but in the adjusted population table 160, one entry corresponds to one time zone as in the estimated population table 140 (FIG. 7).

  Note that the seasonal adjustment unit 120 does not process all entries included in the array table 150 but only selected entries (for example, only entries whose estimated population in the time zone immediately before the current time is equal to or greater than a predetermined threshold). It is preferable to execute a seasonal adjustment process. This is because the calculation load is reduced.

  The area extraction unit 130 refers to the adjusted population table 160 and extracts a congested area CA in which the estimated population is concentrated (increase) (S1050).

More specifically, first, the area extraction unit 130, for each entry in the adjusted population table 160 based on the following relational expression, σ _sadj indicating the deviation of the adjusted estimated population from the long-term moving average and the long-term Calculate _Msadj , which indicates the ratio of the adjusted estimated population to the moving average.
σ _sadj = (adjusted estimated population-long-term moving average) / standard deviation (Equation 1)
M _sadj = adjusted population / long-term moving average ... (Formula 2)
Thereafter, the area extracting unit 130, a first rank when sorted according congestion indicator I _C (e.g., 10 positions) by extracting the entry to be above, and stores the extracted area table 230 (FIG. 10) with sorting order. The above rankings may be nationwide rankings or rankings by prefecture. Incidentally, the area extracting unit 130, in step S1050, extracts the entry congestion indicator I _C exceeds the first threshold value, may be stored in the extracted area table 230.

Regarding the congestion index I _C , only one of σ _sadj and M _sadj may be used as the congestion index I _C , or an index based on both (for example, I _C = α · σ _sadj + β · M _{sadj. Α} and β it may be a congestion indicator I _C weighting factor).

Further, in step S1050, estimated population may be estimated subject to only congestion indicator I _C or more entries predetermined threshold. Be greater congestion indicator I _C showing the increase in estimated population is, the estimated population itself because it can not be said that fewer if congestion area CA. By selecting the target entries as described above, the amount of calculation can be reduced.

As described above, the congestion analysis server AS serves as congestion index acquiring unit that acquires congestion indicator I _C about congestion degree in each area A. Through the above area extraction operation (congestion index acquisition operation), the combination of the congestion area CA and the time zone in which the population (estimated population after seasonal adjustment) is concentrated is extracted and stored in the extraction area table 230.

1 (4) -2. Index Operation FIG. 11 is a flowchart showing the index operation of the present embodiment. Schematically, the index unit 300 of the index server IS extracts and indexes post information PI having information (POI name or geotag) related to the position from the post information PI acquired from the blog server BS. “POI” is an abbreviation of “Point of Interest”, and means “a place that attracts people's interests” such as landmarks, historical sites, and stores. “Geotag” is information indicating latitude and longitude, and is acquired based on the GPS function, for example.

  The index unit 300 acquires post information PI from the blog server BS (S1110). All post information PI posted to the blog server BS may be provided to the index server IS, or post information PI selected based on a predetermined condition may be provided to the index server IS. The posting information PI may be provided in real time or may be provided at predetermined time intervals.

  FIG. 12 shows an example of post information PI provided from the blog server BS. The post information PI includes a “post ID” field that uniquely identifies the post, a “post time” field, a “latitude” field and a “longitude” field that indicate the position where the post is made, and a “post information body” field. . The “latitude” and “longitude” fields may be blank depending on the setting of the posting user and other factors.

  The index unit 300 determines whether or not the POI name registered in the dictionary table 310 (FIG. 13) is included in the “post information body” field for each acquired post information PI (S1120). If the POI name is not included (S1120; NO), the process proceeds to step S1150. In step S1120, when the posted information PI includes latitude and longitude, the process may proceed to step S1150 regardless of whether the POI name is included.

  On the other hand, when the POI name is included in the “post information body” field (S1120; YES), the index unit 300 refers to the dictionary table 310 and posts the POI name and the POI identifier corresponding to the POI name to the post. It is given to the information PI (S1130). Then, the index unit 300 adds the latitude and longitude corresponding to the POI name to the posted information PI (S1140). Posting information PI after the above assignment is executed is shown in FIG. In the example of FIG. 14, for post information PI having post ID 98654543, “POI identifier”, “POI name”, “latitude”, and “longitude” are based on the POI name “Kinkakuji” included in the post information body. A value is assigned to each field.

  If the POI name is included in the “posted information body” field, and the latitude and longitude are already included in the posted information PI, the addition of latitude and longitude in step S1140 may be skipped. Further, when a plurality of POI names are included in the “posted information body” field, a plurality of POI information (POI identifier, POI name, latitude, and longitude) may be associated with one post information PI. Good.

  Next, the index unit 300 determines whether the acquired post information PI includes latitude and longitude (S1150). If the latitude and longitude are not included (S1150; NO), the process returns to step S1110, and new post information PI is acquired.

  On the other hand, when the latitude and longitude are included in the posted information PI (S1150; YES), the index unit 300 identifies a mesh code corresponding to the latitude and longitude and assigns it to the posted information PI (S1160). Thereafter, the index unit 300 stores the posting information PI in the extracted posting table 320 and assigns an index for facilitating the search (S1170). FIG. 15 is a diagram showing post information PI assigned with a mesh code and stored in the extracted post table 320. Thereafter, the operation returns to step S1110, and new post information PI is acquired.

  By the above index operation, post information PI having information (geographic attribute) related to the position is extracted, indexed, and stored in the extracted post table 320.

1 (4) -3. Posting Information Analysis Operation FIG. 16 is a flowchart showing the posting information analysis operation of the present embodiment. The second query portion 212 of the web server WS acquires post information PI from the index server IS (extracted Post table 320), and calculates the total number of posts _{S C} posted information PI for each time slot as a POI and per subject . For example, the second query unit 212 uses the total number of posts S of the posting information PI for POI = Kinkakuji and target time zone = 2014/5/5 10:00:00 to 2014/5/5 10:59:59. _C is calculated. Then, a list of combinations of POIs and target time zones (increased POI candidates) in which the total number of posts of the posting information PI is equal to or greater than the threshold N is listed (S1210).

The second query unit 212 calculates, for each of the listed POI and target time zone combinations, the total number of posts S _L of post information PI over a long period (for example, one day) including the target time zone (S1220). . For example, the second query unit 212 uses the total posting number S _L of the posting information PI for POI = Kinkakuji and past period = 2014/5/4 11:00:00 to 2014/5/5 10:59:59. Is calculated.

For each of the listed POI and target time zone combinations (increased POI candidates), the second query unit 212 follows the following Expression 3 to indicate the second posting index I _P2 (second interest) Index) is calculated (S1230).
I _P2 = log {S _C / (S _L + V)} (Formula 3)
“V” in Expression 3 is a smoothing parameter that takes a positive value, and is a value for correcting the second posting index I _P2 to be smaller when the absolute number of postings is small.

The second query unit 212, based on the second post index _{I P2} extracts the combination of the POI and the target time zone is stored in the post rising table 260 (S1240). More specifically, the second query portion 212, a second order when sorted according to a second post index I _P2 (e.g., position 8) for the combination of POI and target time period equal to or greater than a time zone, POI identifier , POI names, and generates an entry including the mesh code, POI latitude, POI longitude, and the second post index _{I P2,} and stores it in the post rising table 260. FIG. 17 shows a configuration example of the posting increase table 260.

Note that, in step S1240, the second query portion 212, a second post index I _P2 extracts the combination of the POI and the target time period exceeds a third threshold value may be stored in a post rising table 260.

  Thereafter, the second query unit 212 stores post information PI corresponding to the combination of the extracted POI and the target time zone in the post information table 250 (S1250).

  Through the post information analysis operation described above, the POI in which the number of posts in the post information PI is increasing (increasing) and the combination of time zones (rising POI) are extracted and stored in the post ascending table 260.

In the post information analysis operation described above, analysis is executed in units of POIs, but a configuration in which analysis is executed in units of mesh codes (area A) can also be adopted. That is, even if the second query unit 212 calculates S _C , S _L , and the second posting index I _P2 (second interest index) for each mesh code and for each target time zone, the above extraction operation is executed. Good. In this case, in step S1240, for the combination of the mesh code and the target time zone, the time zone, the mesh code, the mesh latitude (the upper left point of the mesh), the longitude of the mesh (the lower right point of the mesh), and the second posting index entry containing the I _P2 is produced and stored.

1 (4) -4. Posting Information Saving Operation FIG. 18 is a flowchart showing the posting information saving operation of the present embodiment. The area acquisition unit 222 of the web server WS acquires information on the congestion area CA included in the extraction area table 230 (combination of the mesh code of the congestion area CA and the target time zone in which the congestion has occurred), and sends the information to the third query unit 224. Supply (S1310).

  The third query unit 224 uses the mesh code supplied from the area acquisition unit 222 and the post information PI corresponding to the target time zone (that is, the post information PI corresponding to the congested area CA) to the extraction post table 320 of the index server IS. (S1320). Next, in addition to storing the acquired posting information PI in the posting information table 250, the third query unit 224, when the acquired posting information PI includes image information (such as an image URL on the Internet), the image information Is stored in the image table 240 together with the posting ID included in the posting information PI (S1330).

  Through the above post information storage operation, post information PI and related images corresponding to the congested area CA are stored in the web server WS. According to the above configuration, the old posting information PI is periodically deleted in the extraction posting table 320 of the index server IS, and the related image can be presented to the client terminal CL even if it is lost from the Internet over time. The posting information PI and the related image having the property are secured in the web server WS.

  It should be noted that a configuration in which the image data itself is not acquired in the above post information storage operation can be employed. For example, in the above step S1330, the third query unit 224 determines whether the URL included in the acquired post information PI corresponds to an image (that is, whether the post information PI includes image information). ) And information indicating the determination result (with / without image) may be stored in the image table 240 together with the posting ID.

1 (4) -5. Data Presentation Operation The data presentation unit 200 of the web server WS presents various data to the client terminal CL based on the entries stored in the tables (230, 240, 250, 260) by the above-described operation.

1 (4) -5-1. Congested Area Presenting Operation FIG. 19 is a flowchart of an operation for presenting a congested area CA to the client terminal CL. When the first query unit (first interest index acquisition unit) 202 of the data presentation unit 200 receives a congestion area display request including the specified date and time and the specified display range from the client terminal CL (S1410), the first query unit (first interest index acquisition unit) 202 A corresponding entry (congested area CA) is acquired from the extraction area table 230 (S1420). That is, the first query unit 202 converts the requested designated display range into a mesh code, and then includes any one of the mesh codes corresponding to the designated display range, including the designated date and time in the period indicated by the “time zone” field. Search and obtain display candidate entries included in the “mesh code” field. The acquired display candidate entry is supplied to the place presentation unit 204.

Next, the first query unit 202 acquires posted information PI corresponding to the time zone and mesh code indicated by the acquired display candidate entry from the posted information table 250 (S1430), and posted information PI corresponding to each display candidate entry. The first posting index I _P1 (first interest index) indicating the number of items is calculated and supplied to the place presentation unit 204 (S1440).

Location presentation unit 204, among the display candidate entries extracted based on the congestion indicator I _C, congested areas first post index I _P1 corresponds to the entry of more than a second threshold value CA (time zone and the mesh code), It is presented to the client terminal CL (S1450). That is, the place presentation unit 204 transmits a control signal for displaying the congestion area CA in the first mode along with the electronic map on the display of the client terminal CL to the client terminal CL.

  Thereafter, the client terminal CL displays the congestion area CA on the display in accordance with the control signal received from the location presentation unit 204. FIG. 20 is an example of an image G displayed on the display. The image G includes a date and time designation part DD, an electronic map part EM, and an information display part ID. The date and time designation part DD is a part for designating a designated date and time in the display request, and includes a date designation calendar and a time designation slider.

  The electronic map part EM is a part for designating a designated display range in the display request in addition to the display area of the electronic map and the congestion area CA. By scrolling the electronic map displayed on the electronic map unit EM with a mouse or the like, the designated display range included in the congestion area display request also changes. As shown in FIG. 20, the electronic map unit EM displays a congestion box B1 corresponding to the congestion area CA (time zone and mesh code) presented in step S1450. The congestion box B1 is an example of a first aspect. Details of the information display unit ID will be described later.

1 (4) -5-2. FIG. 21 is a flowchart of an operation for presenting, to the client terminal CL, a POI (increased POI) in which the number of posts in the posted information PI is increasing. When receiving the rising POI display request including the specified date and time and the specified display range from the client terminal CL (S1510), the first query unit 202 acquires an entry corresponding to the rising POI display request from the posting rising table 260 (S1520). ). That is, the first query unit 202 searches for a display target entry that includes the specified date and time in the period indicated by the “time zone” field and includes the latitude and longitude indicated by the “latitude” field and the “longitude” field in the specified display range. Get. The acquired display target entry is supplied to the place presentation unit 204.

  The location presenting unit 204 presents the rising POI (time zone and latitude / longitude) corresponding to the acquired display target entry to the client terminal CL (S1530). That is, the place presentation unit 204 transmits a control signal for displaying the rising POI in the second mode together with the electronic map on the display of the client terminal CL to the client terminal CL.

  Thereafter, the client terminal CL displays the rising POI on the display according to the control signal received from the location presenting unit 204. FIG. 22 is an example of an image G displayed on the display, and includes the same portions (DD, EM, ID) as FIG. As shown in FIG. 22, the electronic map unit EM displays a rising box B2 corresponding to the rising POI (time zone and latitude / longitude) presented in step S1530. The rising box B2 is an example of a second mode different from the first mode.

  In addition, the structure which performs the above presentation operation | movement about the area A (rising area) where the posting number of contribution information PI is rising is also employable similarly to the above-mentioned contribution information analysis operation (item 1 (4) -3). It is. Furthermore, it is also possible to employ a configuration in which the presentation operation for the rising POI and the presentation operation for the rising area are executed together.

1 (4) -5-3. Operation for Presenting Congestion Related Information FIG. 23 is a flowchart of an operation for presenting the congestion related information CI related to the congestion status of the congestion area CA to the client terminal CL. When the first query unit 202 receives an information display request designating a specific congestion area CA from the client terminal CL (S1610), the first query unit 202 sets the posting information PI associated with the congestion area CA (mesh code and time zone) as posting information. Obtained from the table 250 and supplied to the information presentation unit 206 (S1620). The information display request in step S1610 is generated, for example, when the user selects the congestion box B1 displayed on the electronic map unit EM with an input device such as a mouse.

The information presentation unit 206 handles the supplied post information PI as the congestion related information CI. This is because the post information PI associated with the congestion area CA is highly likely to be related to the congestion situation and the reason for the congestion area CA. The information presentation unit 206 determines a priority according to the information value for each of the congestion related information CI acquired for the congestion area CA (S1630). The above priorities can be arbitrarily determined. Examples of priority determination methods are listed below without limitation. A plurality of priority determination methods may be used in combination.
-The higher the posting time of the congestion related information CI, the higher the priority-The higher the priority, the higher the number of times the congestion related information CI is shared (retweeted or shared)-The congestion including the image (image link URL) Increase the priority of the related information CI-increase the priority of the congestion related information CI including the POI name in the congestion area CA

  The information presentation unit 206 presents the congestion related information CI to the client terminal CL according to the priority (S1640). For example, the information presentation unit 206 may present the congestion related information CI sorted according to the priority to the client terminal CL, or may present the congestion related information CI having the highest priority to the client terminal CL.

  Thereafter, the client terminal CL displays the congestion related information CI presented from the information presentation unit 206 on the display (information display unit ID). FIG. 24 is an example of an image G displayed on the display. In the information display part ID, congestion related information CI to which priority is given according to the posting time is displayed. The image data corresponding to the congestion related information CI (post information PI) may be acquired from the image table 240 by the information presentation unit 206 and presented to the client terminal CL, or an image included in the congestion related information CI. You may acquire and show from the internet based on information (image link URL). Further, the client terminal CL may obtain from the Internet based on the congestion related information CI presented from the information presentation unit 206.

  The post information PI (congestion related information CI) corresponding to the congestion area CA is displayed together with the electronic map by the above operation, but the same operation is performed for the post information PI corresponding to the rising POI (or rising mesh). It is possible to display based on

1 (5). Effects of the Embodiment According to the configuration of the present embodiment described above, the crowded area CA where the population is concentrated and the congestion related information CI related to the congestion status of the crowded area CA are combined with the client terminal CL. Presented and displayed with electronic map. Therefore, the value of the information provided to the user is higher than the configuration in which only the area where the population is concentrated is presented.

  In the present embodiment, in addition to the crowded area CA, a place where the number of posts of the posting information PI is rising (rising POI or rising area) is presented to the client terminal CL and displayed together with the electronic map. That is, although it is not actually crowded, the user is notified of places where many people are interested.

  In the present embodiment, the congestion related information CI is presented according to the priority according to the information value. Therefore, more meaningful information is preferentially provided to the user.

2. Modifications The above embodiment can be variously modified. Specific modifications are exemplified below. Two or more aspects arbitrarily selected from the above embodiments and the following examples can be appropriately combined as long as they do not contradict each other.

2 (1). Modification 1 (interest information)
Various information other than the posted information PI can be adopted as the interest information. For example, a search history SH input to a search server that provides an Internet search service can be used as interest information. The search history SH, like the post information PI provided from the blog server BS, includes “search time”, “latitude” and “longitude” indicating the position where the search has been performed, and “search word” as information items (fields). ) Included. Therefore, when the index server IS acquires the search history SH from the search server, it is possible to realize the same operation as in the above-described embodiment.

  Also, an access history AH to a POI information server that provides information related to POI can be used as interest information. The access history AH described above includes “access time”, “latitude” and “longitude” indicating the position where the access has been performed, and “access target POI” as information items (fields). Therefore, when the index server IS acquires the access history AH from the POI information server, it is possible to realize the same operation as in the above-described embodiment.

  Furthermore, it is good also as interest information combining 2 or more information. More specifically, the index server IS has a plurality of types of information (post information PI, search history SH, access history AH) having geographical attributes from a plurality of servers (blog server BS, search server, POI information server, etc.). Etc.) may be acquired and stored, and used for location presentation and information presentation executed by the web server WS. In calculating the interest index (first interest index and second interest index), weighting may be performed according to the type of information.

2 (2). Modification 2 (congestion index)
In the above embodiments, estimated population parameter indicating time-series changes in the (congestion degree) (sigma _SADJ, M _SADJ, or combinations thereof) but is employed as a congestion indicator I _C, estimated population (congestion degree) itself may be employed as the congestion indicator I _C.

2 (3). Modification 3 (first interest index)
In the above embodiment, the first posting index I _P1 (first interest index) indicates the number of posting information PI in the congested area CA in the specified time zone. However, the first posting index I _P1 may indicate an index indicating the propagation power of the posting information PI (for example, the number of times the posting information PI is shared (the number of retweets)).

2 (4). Modified example 4 (congestion related information)
In the above embodiment (steps S1610 to S1640), the post information PI is presented to the client terminal CL as the congestion related information CI. However, other information as described below may be presented as the congestion related information CI.

2 (4) -1. Presentation of Event Name The information presentation unit 206 may present the event name included in the posted information PI associated with the congestion area CA (mesh code and time zone) as the congestion related information CI. The event name may be acquired by matching the event name dictionary data stored in the web server WS in advance with the extracted word from the posting information PI, or may be acquired by syntax analysis. As an example of parsing, obtain a noun prefixed to a string that tends to be used with the event name (for example, “(Event name) is held” or “(Event name) participates”) as the event name. A configuration is mentioned.

  When a plurality of event names are acquired, it is preferable that the event names are presented to the client terminal CL based on the event priority. Regarding the above priorities, for example, the higher the number of post information PI including an event name, the higher the priority of the event is determined.

2 (4) -2. Presentation of Photo Image The information presentation unit 206 may present a photo image linked to the post information PI associated with the congestion area CA as the congestion related information CI. When there are a plurality of photographic images, it is preferable that the photographic images are presented to the client terminal CL based on a priority that increases as the number of people in the image acquired by the person recognition process increases.

2 (5). Modification 5 (area)
A region other than the mesh can also be adopted as the area A. For example, a circular area centered on a predetermined landmark may be used as the area A. An area A surrounded by the outer edge of a spot such as a building or a park may be used as the area A.

2 (6). Modification 6 (presentation system and presentation device)
In the above embodiment, the congestion analysis server AS and the web server WS exist separately in the presentation system PS, but the congestion analysis server AS and the web server WS may be configured as one presentation device. However, while the congestion analysis server AS includes personal information indicating the behavior of the mobile phone user, the web server WS has a feature that only statistically processed information is stored and released to the outside. The configuration of the embodiment in which each of the above servers is provided separately is suitable.

  On the other hand, each server (congestion analysis server AS, web server WS, etc.) may be realized by a plurality of computer devices connected to each other via a network.

  A configuration in which an index server IS is included in the presentation system PS can also be employed.

2 (7). Modification 7 (client terminal as a presentation device)
The above-described operation executed in the congestion analysis server AS and the web server WS may be executed in the client terminal CL. That is, the client terminal CL can function as a presentation device.

2 (8). Modification 8 (sort processing)
In the above embodiment (step S1050), the congestion index I _C having a higher degree of congestion increase as the value increases, is sorted in descending order to determine the rank of entries. However, the congestion index I _C having a higher degree of congestion increase as the value is smaller may be adopted, and the rank of entries may be determined by sorting the congestion index I _C in ascending order. The same applies to sorting according to a second post index I _P2 in step S1240.

2 (9). Modification 9 (sorting according to the first interest index)
In step S1240, sorting is performed according to the second posting index I _P2 (second interest index) indicating the quantitative change in the number of postings, but sorting is performed according to the first posting index I _P1 (first interest index) indicating the number of postings. May be executed.

2 (10). Modification 10 (variable threshold)
The first threshold value and the second threshold value may be set variably. For example, the higher the congestion index I _C , the lower the second threshold for the first posting index I _P1 (first interest index), and the higher the first posting index I _P1, the first threshold for the congestion index I _C is set. It is preferable. According to the above configuration, in the congestion area determination based on the double condition using the first threshold value and the second threshold value, the other threshold value decreases as the value compared with one threshold value increases. Is easily satisfied. Therefore, cases where the area is determined to be a congested area CA increase, and as a result, the amount of information presented to the user increases.

On the other hand, the higher the congestion index I _C , the higher the second threshold for the first posting index I _P1 (first interest index) may be set, and the higher the first posting index I _P1, the first threshold for the congestion index I _C. May be set higher. Generally, the congestion indicator I _C and the first post indicator I _P1 for area A because it is expected to have a positive correlation, the other the threshold is also set high enough increases the value to be compared with one threshold value Thus, the determination accuracy of the congestion area CA can be improved.

Further, the second threshold value related to the first posting index I _P1 (first interest index) may be variably set based on another index. For example, the second threshold value of the area A may be set higher as the index (for example, population density) related to the urban degree assigned to the area A is higher.

2 (11). Modification 11 (area presentation according to the third aspect)
Further presentation modes may be adopted for the congestion area CA. For example, the congestion indicator I _C exceeds a first threshold, and second posts index I _P2 indicating the quantitative changes in the number of posts is the area A above the third threshold value, location presentation unit 204 presents the third aspect. That is, the place presentation unit 204 transmits a control signal for displaying not the congestion box B1 but the attention box B3 (FIG. 25) in the area A on the electronic map unit EM to the client terminal CL. According to the above configuration, the area A where the population is concentrated and the number of posts is increasing is explicitly presented.

2 (12). Modification 12 (area presentation according to the fourth aspect)
Event information may be displayed on the electronic map unit EM in addition to the crowded area CA and the post number increasing location (rising POI, rising mesh). As shown in FIG. 26, the web server WS of the present modification further includes an event information table 270 that stores event information entries. The event information entry includes an event name, an event date and time, and a geographical attribute (POI, latitude / longitude) of the event location.

  When the first query unit 202 receives an event display request including the specified date and time and the specified display range from the client terminal CL, the first query unit 202 acquires an event information entry corresponding to the specified date and time and the specified display range from the event information table 270. To the place presentation unit 204. The location presenting unit 204 presents the area A corresponding to the acquired event information entry to the client terminal CL. That is, the place presentation unit 204 transmits a control signal for displaying the area A where the event is held on the display of the client terminal CL in the fourth mode. An event box B4 (FIG. 27) corresponding to the area A is displayed on the electronic map part EM of the display. According to the above configuration, the location and the date and time where the event is held are explicitly presented.

The location presenting unit 204 presents the area A only when the first posting index _IP1 indicating the number of postings in the area A exceeds the fourth threshold for the area A corresponding to the event information entry. Good. The fourth threshold value may be equal to or different from the second threshold value in step S1450. According to the above configuration, since an event whose number of posts does not satisfy the standard is not presented to the client terminal CL, the event that is actually the topic is selected.

2 (13). Modification 13 (Non-presentation of location where the number of posts has increased)
It is also possible to adopt a configuration (a configuration in which only the congested area CA is presented) in which the location (the increased POI or the increased area) where the number of posts of the posted information PI is increasing is not presented to the client terminal CL. In the above case, it is understood that the posting information analysis operation for specifying the rising POI or the rising area is not necessary.

2 (14). Modification 14 (change in box size)
Depending on the congestion indicator I _C, presenting congestion area CA corresponding may vary. For example, the higher the busy indicator I _C, it may be displayed larger congestion box B1. Similarly, the presentation mode of the rising POI or the rising area (for example, the size of the rising box B2) may be changed according to the first posting index I _P1 or the second posting index I _P2 .

2 (15). Modification 15 (Integration of multiple boxes)
When the scale of the electronic map is changed and a plurality of boxes must be displayed in a predetermined narrow area, it is preferable that the plurality of boxes are combined into one integrated box and displayed together with the total number of boxes to be originally displayed. is there.

2 (16). Modification 16 (Aspect indication mode)
In the above embodiment, the area A is indicated by displaying a box such as the congestion box B1. However, the area A may be indicated by a mode other than the box (for example, change in display color of the area A).

2 (17). Modification 17 (Place presentation)
The place presentation mode executed by the place presentation unit 204 is not limited to box display on an electronic map. For example, in step S1450, where presentation unit 204, predetermined order congestion area CA (e.g., congestion index I _C higher order) may be used to control the client terminal CL so as to display a list format. That is, the list of crowded areas CA is an example of the first aspect.

  The above list of the congested areas CA may be displayed alone (that is, independently of the electronic map) on the display of the client terminal CL, or may be displayed together with the electronic map. When the list is displayed together with the electronic map, when the user selects one of the congestion areas CA on the list, the congestion box B1 is displayed at a position on the electronic map corresponding to the congestion area CA. More preferred.

  Similarly, the location presenting unit 204 may control the client terminal CL to display the rising POI or the rising area where the number of postings of the posting information PI is increasing in a list format. That is, the rising POI or the rising area list is an example of the second mode. Moreover, the display of the list format similar to the above can be adopted also for the place presentation described above with respect to the modified examples 11 and 12.

2 (18). Modification 18 (Device other than CPU)
Each function executed by the CPU in the computer apparatus, in particular, the congestion analysis server AS, the web server WS, and the index server IS is executed by a programmable logic device such as an FPGA (Field Programmable Gate Array) or a DSP (Digital Signal Processor). Also good.
