The spot dictionary is a list of names of unique spots such as “ABC restaurant” and “DEF stadium”. A wide area, a prefecture, an area, a city, and a spot have a relationship in which the wide area includes the prefecture, the prefecture includes the area, the area includes the city, and the city includes the spot. Have.
Since administrative units and areas are specific to each country, the region-related word dictionary ST31 may store a different dictionary set for each country. For example, in the case of the United States, an area dictionary, a state dictionary, a county dictionary, a municipality dictionary, a spot dictionary, or the like for an area including a plurality of states may be provided. In the present embodiment, description will be given assuming administrative units and areas in Japan.

As shown in FIG. 6A, in this embodiment, five levels of detail, “1” to “5”, are set according to the scale of the map. In the example shown in the figure, the level of detail “1” is used for the map scale range “less than 1 / 350,000”, and the level of detail “2” is used for “1 / 350,000 and less than 1 / 70,000”. Level of detail is “3” for “less than 1 / 24,000”, level of detail “4” for “1 / 24,000 and under 1 / 8,000”, and level of detail “5” for “1 / 8,000 and above” Is set.
As shown in FIG. 6B, in the region-related word dictionary ST31, a global dictionary, a prefecture dictionary, an area dictionary, a municipality dictionary, and a spot dictionary are stored in association with each level of detail. . Specifically, the level of detail level “1” is a wide dictionary, the level of detail “2” is a prefecture dictionary, the level of detail “2” is a prefecture dictionary, and the level of detail is “3”. Is stored in association with the area dictionary, the municipality dictionary associated with the detail level “4”, and the spot dictionary associated with the detail level “5”. The range of the map scale associated with each level of detail can be determined as appropriate in relation to the size of the display area 12a in a display device such as the mobile terminal device 10.
As described above, the storage device 34c associates each of the plurality of detail levels corresponding to the map scale with the region-related words related to the region suitable for the range on the map displayed according to each scale. It functions as the stored first storage unit.

  As shown in FIG. 6C, in the article table TBL31 of the present embodiment, each article provided from the blog server 20 is associated with the ID of each article in association with the posting time (transmission time), latitude, and the like. The longitude information, the account name of the article sender, the article text, and the level of detail are stored.

As illustrated in FIG. 5, the CPU 31 includes an article acquisition unit 31 a, a grant unit 31 b, and a transmission unit 31 c as functional elements.
The article acquisition unit 31a acquires an article related to a region or a point among articles provided from the blog server 20. Specifically, the article acquisition unit 31a acquires an article to which a geotag (latitude and longitude information) is attached from among the articles received from the blog server 20, and morphologically analyzes the article text to obtain a spot name or a spot. Get articles containing words related to. The article acquisition unit 31a additionally stores the newly acquired article as a new record in the article table TBL31. The new record has an article ID, an article posting time, latitude / longitude information, an account name, and an article text. The article acquisition unit 31a stores the geotag as latitude / longitude information when a geotag is attached to the article. If the article includes a spot name or a word related to the spot, the latitude / longitude information corresponding to the spot is acquired and stored as latitude / longitude information. That is, an article related to a region or a point is an article in which a word associated with a spot name or spot is included in an article or article text to which a geotag is attached, and is indicated by a geotag in the article table TBL31. At least one of the latitude / longitude information and the latitude / longitude information corresponding to the spot is stored in association with each other.
Thus, the CPU 31 functions as an acquisition unit that acquires a plurality of articles related to a region or a spot.

The assigning unit 31b assigns a level of detail to the article acquired by the article acquiring unit 31a. Specifically, among the plurality of articles acquired by the article acquisition unit 31a, the areas included in the wide area dictionary, prefecture dictionary, area dictionary, city dictionary, and spot dictionary stored in the area related word dictionary ST31 The level of detail stored in association with the region-related word included in the article is assigned to the article including any of the related words.
Here, when one article includes, for example, the character string “AAA prefecture ccc city”, “AAA prefecture” belonging to the prefecture dictionary and “ccc city” belonging to the municipality dictionary are extracted. . The assigning unit 31b assigns a detail level corresponding to the largest scale to an article including a plurality of region-related words having different detail levels. Therefore, in the case of the above example, the level of detail “4” corresponding to the municipality dictionary is given.
The assigning unit 31b stores the assigned detail level in the corresponding record of the article table TBL31.
Thus, CPU31 respond | corresponds to the said area related word to the article containing either of the area related words memorize | stored in the area related word dictionary ST31 of the memory | storage device 34c among the some articles which the article acquisition part 31a acquired. It functions as a granting unit that gives a level of detail.

Upon receiving the display request from the mobile terminal device 10, the transmission unit 31c specifies the level of detail and the display range corresponding to the scale of the predetermined map or the map scale included in the display request, and the articles belonging to the specified display range Among the articles (that is, articles having latitude / longitude information within the display range), an article assigned with the specified level of detail is identified. Then, the map image of the map corresponding to the display range and the information of the identified article are transmitted to the mobile terminal device 10 via the transmission / reception unit 33.
As described above, the CPU 31 and the transmission / reception unit 33 are articles that belong to the range of the map displayed on the mobile terminal device 10 and are given the level of detail corresponding to the scale of the map displayed on the mobile terminal device 10. As displayed on the mobile terminal device 10, it functions as a transmission unit that transmits article information to the mobile terminal device 10.

  By the way, since the display range of the map displayed on the touch panel 12 of the portable terminal device 10 changes according to the scale of the displayed map, it corresponds to the article (more precisely, the display range) displayed in the display range. The number of articles) having latitude and longitude information in the map area increases or decreases according to the scale. However, since the size of the display area 12a on the touch panel 12 of the mobile terminal device 10 is constant, if the scale of the map is small (that is, the map is in a wide area display), the number of articles in the display range is large. The density of articles displayed in the displayed display area 12a may be excessive, and visibility may be lost. Therefore, the blog map providing server 30 (display control device) of the present embodiment previously gives a level of detail corresponding to the scale of the map to each of a plurality of articles related to the area or spot received from the blog server 20. In addition, in response to a display request from the mobile terminal device 10, an article related to an area suitable for a map display range determined according to a map scale (that is, a map that belongs to the displayed map range and is displayed) And the information of these articles is transmitted to the mobile terminal device 10 so that these articles are displayed on the mobile terminal device 10. Yes.

<Operation>
Next, the operation of this embodiment will be described.
FIG. 7 is a sequence chart showing the overall operation flow according to the present embodiment. As shown in the figure, the CPU 31 of the blog map providing server 30 obtains an article including an article attached with a geotag and a word related to a spot name or a spot each time an article is transmitted from the blog server 20. Then, the article is stored as a new record in the article table TBL31 (Sb1).

Next, every time a new record is added to the article table TBL31, the CPU 31 executes an assigning process for giving a detail level to the newly stored article (Sb2).
FIG. 8 is a flowchart showing a detailed flow of the providing process according to the present embodiment. As shown in the figure, the CPU 31 first performs a morphological analysis on the article text stored in the article table TBL31 (S11), and the article text includes a region-related word stored in the region-related word dictionary ST31. (S12: YES), the level of detail corresponding to the region-related word is assigned and stored in the record of the article in the article table TBL31 (S13). For example, in the article table TBL31, the word “A region” included in the article text of the record having the article ID “0001” is an area related word stored as a wide area dictionary. Therefore, the detail level “1” is given to the article having the article ID “0001”. In the article table TBL31, the word “DEF stadium” included in the article text of the record having the article ID “0002” is a region-related word stored as a spot dictionary. Therefore, the detail level “5” is assigned to the article having the article ID “0002”. Subsequently, in step S14, the CPU 31 determines whether or not the article includes an undetermined area-related word. If the determination result is YES, the CPU 31 returns to step S13 to determine the undetermined area-related word. Determine the corresponding level of detail. On the other hand, when the determination result of step S14 is NO, the grant process ends.

  As described above, when an article includes the character string “AA prefecture ccc city”, the detail level “2” corresponding to “AA prefecture” and the detail level corresponding to “ccc city” “4” will be given. The CPU 31 assigns a detail level corresponding to the largest scale to an article including a plurality of regional related words having different detail levels. That is, when the level of detail level “2” is stored in the article table TBL31, and the CPU 31 further extracts an area-related word corresponding to the level of detail level “4”, the CPU 31 stores the detail level stored in the article table TBL31. Overwrite level “2” with level of detail “4”. In addition, when the detail level “4” is stored in the article table TBL31, when the region-related word corresponding to the detail level “2” is extracted, the stored contents of the article table TBL31 are retained.

On the other hand, when the article text does not include the area-related word stored in the area-related word dictionary ST31 (S12: NO), the process proceeds to step S14, and the CPU 31 determines that the article is an undetermined area-related word. Whether or not is included is determined. If the determination result is YES, the process returns to step S13 to determine the level of detail corresponding to the undetermined area related word. On the other hand, when the determination result of step S14 is NO, the grant process ends.
Even if a geotag is attached, the level of detail is not assigned to an article whose article text does not contain a region-related word. In this case, the “detail level” of the record of the article in the article table TBL31 is blank.

  Subsequently, returning to FIG. 7, when the user of the mobile terminal device 10 activates the blog map application, the mobile terminal device 10 indicates position information (specifically) indicating the current position of the mobile terminal device 10 to the blog map providing server 30. Specifically, when a display request including latitude / longitude information acquired by the GPS function of the mobile terminal device 10) or position information of an arbitrary place is transmitted, the CPU 31 displays a map area including the position information included in the display request. Then, the range of the map corresponding to the scale corresponding to the predetermined zoom level is specified as the display range, and the level of detail corresponding to the predetermined scale among the articles having the latitude and longitude information belonging to the display range (this implementation) In the example, an article to which “4”) is assigned is read from the article table TBL31, and article information is transmitted to the mobile terminal device 10 (Sb3). Specifically, the CPU 31 acquires a map image of a map area corresponding to the display range from the map providing server 40, and the blog in which the read article is displayed on the mobile terminal device 10 along with the map image in a timeline. A map page is generated and transmitted to the mobile terminal device 10. However, in this case, the CPU 31 may transmit the article information read from the article table TBL31 to the mobile terminal device 10 so that the mobile terminal device 10 acquires a map image from the map providing server 40.

When receiving the blog map page from the blog map providing server 30, the mobile terminal device 10 displays the blog map page in the display area 12a of the touch panel 12 (Sa1).
9 to 12A are diagrams illustrating display examples according to the present embodiment. FIG. 9 is a display example corresponding to the level of detail level “1”. As can be understood from FIG. 9, regional related words (“A” suitable for the range on the displayed map (A region in the display example) are shown. Articles including “Region” are displayed on the left side of the map of the A region. As shown in the figure, each article includes a profile icon, an account name, a transmission date and time, and article text. In the timeline display, articles whose transmission time is closer to the present are displayed above. In the lower part of the timeline display area, a “view more” button V for displaying past articles retrospectively is displayed.
FIG. 10 is a display example corresponding to the level of detail level “2”, and an article including an area-related word (“BB city”) suitable for the displayed map of the BB city is displayed. FIG. 11 is a display example corresponding to the level of detail level “4”, and an article including an area-related word (“bbb ward”) suitable for the displayed map of the bbb ward is displayed. FIG. 12A is a display example corresponding to the level of detail level “5”, and area-related words (specific intersection, stadium, park) suitable for the displayed detail map are displayed.

As shown in FIGS. 9 to 12A, a zoom bar Zb for changing the zoom level of the map is displayed on the map. The zoom bar Zb includes a plus icon indicating “enlargement” provided at the upper end of the bar portion and a minus icon indicating “reduction” provided at the lower end, and further includes a plus icon and a minus icon provided by a user operation. And a slider Zs movable between. When the user of the mobile terminal device 10 performs a touch operation of sliding the slider Zs in the direction of the plus icon, the scale of the displayed map increases (the map is enlarged), and conversely, the slider Zs is moved in the direction of the minus icon. When a sliding operation is performed, the scale of the displayed map becomes smaller (the map becomes a wide area display). It should be noted that the zoom bar Zb is merely an example, and of course, other configurations for the user to change the scale of the map can be employed.
In the example in FIG. 7, in step Sa1, an article corresponding to the level of detail level “4” as shown in the display example in FIG. 11 is displayed.

Next, after the user of the mobile terminal device 10 looks at the displayed blog map page, the user performs an operation of sliding the slider Zs of the zoom bar Zb on the map in the direction of the minus icon, thereby reducing the scale of the displayed map. Is input (in this operation example, the scale is changed to a scale corresponding to the level of detail level “1”). When receiving the zoom level change instruction (Sa2), the CPU 11 of the mobile terminal device 10 transmits a display request including designation information for designating the changed zoom level to the blog map providing server 30. When the CPU 31 of the blog map providing server 30 receives a display request from the mobile terminal device 10, the level of detail corresponding to the scale corresponding to the zoom level designated by the designation information (“1” in this operation example) and the display While specifying the range (in this operation example, “A region”), among the articles having the latitude and longitude information belonging to the display range, the article with the detail level “1” is read from the article table TBL31, Article information is transmitted to the mobile terminal device 10 (Sb4).
When the mobile terminal device 10 receives the blog map page from the blog map providing server 30, the article corresponding to the detail level “1” as shown in the display example of FIG. 9 in the display area 12 a of the touch panel 12 (“ The blog map page displaying the article including “A region” in the article text is displayed (Sa3).

  As described above, according to the present embodiment, it is possible to display an article related to an area suitable for the range on the map displayed according to the scale of the map. For example, as shown in the above operation example, when the range displayed according to the scale of the map is a wide area displaying the A region, even if the article has latitude / longitude information within the display range, the display range Only the articles related to the region suitable for the item (that is, the articles related to the wide area) are displayed, and the articles corresponding to the detail levels “2” to “5” corresponding to the larger scale are not displayed. For this reason, the number of articles displayed on the timeline is limited to articles related to an area suitable for the display range, and visibility is improved.

In the present embodiment, an example is shown in which the article is displayed on the left side of the map on the left side of the map. However, the article profile icon, account name, You may make it display the balloon image containing the transmission date and time and the article text. The display by the balloon image may be performed for all of the map displays corresponding to the plurality of detail levels “1” to “5”, or the detail level with a large scale (for example, the detail level “4”). And “5” or “5” only).
FIG. 12B is a diagram illustrating an example in which a balloon image of an article is displayed for a map corresponding to a detail level “5”. In this example, a balloon image of an article with the level of detail level “5” is displayed at the position of the spot related to the article on the map (the position of the latitude and longitude stored in the article table TBL31). In the example shown in the figure, only the article text is displayed in the balloon image. However, an arbitrary combination of at least one of the profile icon, the account name, the transmission date / time, and the article text may be displayed. When the article includes an attached image such as an image, only the attached image may be displayed instead of displaying the article text. According to this aspect, the viewer of the map can grasp the contents of the article at a glance.
In an aspect in which all of the map displays corresponding to the plurality of detail levels “1” to “5” are displayed by the balloon image, the range displayed according to the scale of the map is wide (for example, the A region). In this case, if all articles having latitude / longitude information within the display range are displayed, the density of the articles becomes excessive, the balloon images are overlapped and displayed, and visibility is lacking. However, according to the present embodiment, since only articles related to a region suitable for the range of the displayed map are displayed on the map, visibility is improved particularly when a wide-area map with a small scale is displayed. It becomes possible to do.

Second Embodiment
Next, a second embodiment of the present invention will be described.
In the first embodiment, a geographical name such as a wide-area place name, a prefecture name, a municipality name, an area name, or the like is used as the “region related word”, but in the second embodiment, a geographical name is used as the “region related word”. In addition to the name, a level of detail is given using a word that uniquely recalls or associates a specific area (“specific area related word”). Specific regional terms include dishes and specialties closely related to a specific region (so-called “local gourmet”), and are used for promotional activities such as local specialties and events mainly for the purpose of regional promotion. The mascot character of a specific area (so-called “local character”) is exemplified. In addition, the article text includes words that belong to a specific category, such as weather, disaster, train operation information, traffic congestion information, and tourist information (for example, cherry blossoms, autumn leaves), and events that may occur in relation to the region. A level of detail is also given when a predetermined word to be represented (hereinafter referred to as “event word”) appears together with a geographical name.
In the following description, common reference numerals are used for elements common to the first embodiment, and description thereof is omitted as appropriate.

  FIG. 13 is a block diagram showing a functional configuration of the blog map providing server (display control device) 30B according to the present embodiment. In the blog map providing server 30B, the storage device 34c (first storage unit) includes an area-related word table TBL32 and an event word dictionary ST32 instead of the area-related word dictionary ST31, and the provision unit 31b includes a determination unit 31d. The point is different from the blog map providing server 30 according to the first embodiment.

  The event word dictionary ST32 stores a list of predetermined event words. Event words include weather-related words such as “Sunny”, “Cloudy”, and “Rain”, disaster-related words such as “Earthquake” and “Typhoon”, operational information words such as “Delay” and “Suspension”, Examples include words related to traffic congestion information such as “closed” and “crowded” and words related to tourist information such as “autumn leaves”, “full bloom”, and “sakura”.

  FIG. 14 is a diagram illustrating an example of the contents stored in the region-related word table TBL32. As shown in the figure, the area-related word table TBL32 stores area-related words belonging to the six categories A to F, and the level of detail is assigned to each area-related word. The correspondence between the level of detail and the scale is the same as that described in the first embodiment (FIG. 6A). That is, the level of detail of the map is “1” for the scale range “less than 1 / 350,000”, and the level of detail “2” for the range “1 / 350,000 or more but less than 1 / 70,000” is “1 / 70,000 or more Level of detail "3" is set for "Less than 24,000", Level of detail "4" is set for "Less than 1 / 24,000 and less than 1 / 8,000", and Level of detail "5" is set for "Less than 1 / 8,000" ing.

  In the region-related word table TBL32, any one of “first region-related word”, “second region-related word”, and “third region-related word” is assigned to each region-related word as the type of region-related word. . The first region-related words are, for example, route names such as ABC Shinkansen and YT lines, road names such as Loop No. 8 and AN streets, and articles including the first region-related words include event words (that is, In the case where one region-related word and an event word co-occur), a level of detail corresponding to the first region-related word is given to the article. When the first region-related word is included in an article together with a word related to operation information or a word related to traffic jam information, the article is useful for a user who browses a map of a region range corresponding to the first region-related word. Information. Therefore, in the present embodiment, the level of detail corresponding to the first region-related word is assigned to the article in which the first region-related word and the event word co-occur.

The second region-related words are, for example, wide-area place names such as the A region and the B region, geographical names such as prefectures and city names, and articles including the second region-related words include event words ( That is, in the case where the second region-related word and the event word co-occur, a detail level having a smaller scale than the detail level corresponding to the second region-related word is given. Articles in which the second region-related words co-occur with words related to weather and disasters, and articles in which the second region-related words and words related to tourism information co-occur are in the range corresponding to the second region-related words. It can be useful information not only for maps but also for users who browse a map of a wider area (that is, a map with a smaller scale). Therefore, in the present embodiment, when the article including the second region related word is given a level of detail corresponding to the second region related word, and the article including the second region related word further includes an event word, In addition to the level of detail corresponding to the second region-related word, the level of detail is further reduced. Note that the first region-related word may be arbitrarily used as the second region-related word.
The third region-related word is a specific region-related word (for example, a local gourmet or a local character), and is given a level of detail corresponding to the third region-related word. Since the specific area related word is closely related to the specific area, it can be useful information for the user who browses the map of the specific area.

As shown in FIG. 14, category A includes a wide area name and is assigned a detail level “1”. Category B includes the name of the prefecture, and the detail level “2” is assigned. Category C includes a city name and is assigned a level of detail “4”. Next, category D includes a route name, and an individual level of detail is assigned to each route name. Category E includes a road name, and an individual level of detail is assigned to each road name. The category F includes specific area related words, and an individual level of detail is assigned to each word.
As the level of detail, one or a plurality of levels can be set according to the range of the region that each region-related word recalls. For example, even if the “KH Tohoku Line” is a route that passes through a plurality of prefectures, if the area is an indispensable means of transportation in the individual areas where the route passes, It can be said that this is a region-related word that is also suitable for a narrow region (ie, when the scale is large). Therefore, as shown in the drawing, “KH Tohoku Line” is assigned a detail level “3” having a larger scale in addition to the detail level “2” corresponding to the prefecture.
As described above, the storage device 34c associates, with each of the plurality of detail levels corresponding to the scale of the map, the region-related words related to the region suitable for the range on the map displayed according to each scale. Function as the first storage unit stored in the memory.

  Of the plurality of articles acquired by the article acquisition unit 31a, the determination unit 31d includes any of the event words stored in the event word dictionary ST32 that includes any of the region related words stored in the region related word table TBL32. It is a functional element that determines whether or not it is included, and is realized by the CPU 31B.

FIG. 15 is a flowchart of the grant process according to the present embodiment, and shows a detailed flow of the grant process (Sb7) in FIG.
First, the CPU 31B performs morphological analysis on the article text for the article newly stored in the article table TBL31 in step Sb1 (FIG. 7) (S21). Next, the CPU 31B determines whether or not the article includes an area-related word stored in the area-related word table TBL32 (S22). If the region-related word is not included (S22: NO), the grant process ends.
On the other hand, when the determination result of step S22 is YES, the CPU 31B determines the type of area-related word included in the article (S23). If the area-related word included in the article is the first area-related word, the process proceeds to step S24. If the area-related word is the second area-related word, the process proceeds to step S26. Advances to step S30.

  If the region-related word included in the article is the first region-related word, in step S24, the CPU 31B determines whether the article including the first region-related word includes any of the event words stored in the event word dictionary ST32. Determine whether or not. When this determination result is YES, the CPU 31B gives the detail level stored in the region-related word table TBL32 in association with the first region-related word included in the article to the article table TBL31. (S25). On the other hand, if the determination result in step S24 is NO, that is, if the article does not include an event word, the detail level is not given to the article, and the process proceeds to step S31.

For example, when an article newly stored in the article table TBL31 includes the “YT line” that is the first region-related word and includes the “delay” that is the event word (S24: YES), the region-related word table TBL32 The level of detail “3” stored in association with “YT line” is assigned to the article (S25). Further, when the article newly stored in the article table TBL31 includes “KH Tohoku Line” that is the first region-related word and also includes “delay” that is the event word (S24: YES), the region-related word table Detail levels “2” and “3” stored in association with “KH Tohoku Line” in TBL 32 are assigned to the article (S25).
Thus, CPU31B contains either of the 1st area related words (an example of an area related word) memorize | stored in the area related word table TBL32 of the memory | storage device 34c among the some articles which the article acquisition part 31a acquired. It functions as a grant unit that gives at least one level of detail corresponding to the region-related word to the article, and the grant unit is a predetermined event word that represents an event that may occur in an article that includes the first region-related word A determination unit for determining whether or not an article includes the first region-related word, and determining that the article including the first region-related word includes a predetermined event word, at least one corresponding to the first region-related word included in the article Gives a level of detail.

  Subsequently, the CPU 31B determines whether or not the article includes an undetermined area-related word (S31). If the determination result is YES, the CPU 31B returns to step S23 to determine the undetermined area-related word. Determine the type. If the determination result of step S31 is NO, the grant process ends.

  If it is determined in step S23 that the region-related word included in the article is the second region-related word, the CPU 31B is stored in the region-related word table TBL32 in association with the second region-related word included in the article. Is assigned to the article and stored in the article table TBL31 (S26). Next, the CPU 31B determines whether or not there is a detail level having a smaller scale than the detail level assigned in step S26 (S27). If the determination result is YES, then the second region-related word is subsequently determined. It is determined whether or not an article including the event word (S28). If the article includes an event word (S28: YES), a detail level having a scale smaller than the detail level corresponding to the second region-related word included in the article is assigned to the article and stored in the article table TBL31 ( S29). On the other hand, if it is determined in step S27 that there is no detail level with a small scale (NO), and if it is determined in step S26 that the article does not include an event word (NO), the process proceeds to step S31. .

For example, when “BB Metropolitan Government” and “earthquake” are included in the article (S26: YES), the detail level “2” is assigned to the article in step S26. Since there is a detail level with a scale smaller than the assigned detail level “2”, the determination result in step S27 is YES, and the article has a detail level with a scale smaller than the detail level “2”. “1” is further given and stored in the article table TBL31. As a result, the detail levels “2” and “1” are stored in articles including “BB city” and “earthquake”.
Further, for example, for an article including “BB city” and not including an event word, only the detail level “2” corresponding to “BB city” is given to the article.
For example, when “A region” and “earthquake” are included in the article (S26: YES), the detail level “1” is given to the article in step S27. However, since there is no detail level with a scale smaller than the assigned detail level “2”, the determination result in step S28 is NO. As a result, the detail level “1” is stored in articles including “A region” and “earthquake”. In other words, since there is no level of detail smaller than the level of detail level “1” corresponding to “A region”, articles including “A region” may be included in “A region” regardless of whether or not they include event words. Only the detail level “1” corresponding to “” is given.

  As described above, the CPU 31B includes any one of the second region-related words (an example of region-related words) stored in the region-related word table TBL32 of the storage device 34c among the plurality of articles acquired by the article acquisition unit 31a. It functions as a grant unit that gives at least one level of detail corresponding to the region-related word to the article, and the grant unit is a predetermined event word that represents an event that may occur in an article that includes the second region-related word In addition to the level of detail corresponding to the second region-related word, when it is determined that the article including the second region-related word includes the predetermined event word, A level of detail corresponding to a scale smaller than the scale corresponding to the level of detail is assigned to the article.

  When the region-related word included in the article is the third region-related word, in step S30, the CPU 31B is associated with the third region-related word included in the article and is stored in the region-related word table TBL32. A level is assigned to the article and stored in the article table TBL31 (S25). Subsequently, the process proceeds to step S31.

  For example, when an article newly stored in the article table TBL31 includes “abc-kun”, which is the third region-related word, the level of detail stored in association with “abc-kun” in the region-related word table TBL32. “4” is given to the article (S30). Further, when the article newly stored in the article table TBL31 includes “mnj Manju” which is the third region related word, the level of detail stored in association with “mnj Manju” in the region related word table TBL32. “5” is given to the article (S30).

  In steps Sb3 and Sb4 in FIG. 7, in accordance with a display request from the mobile terminal device 10, a level of detail corresponding to a scale is given among articles belonging to a predetermined scale or a display range corresponding to a specified scale. Displayed articles are displayed. In the present embodiment, in addition to the geographical name, an area-related word (first area-related word and second area-related word) that co-occurs with an event word, and a specific area-related word (first) that uniquely recalls a specific area. Since the level of detail corresponding to the scale is also given to articles including (3 region related terms), the touch panel of the mobile terminal device 10 includes a geographical name suitable for the region in the displayed range. An article including an article, a geographical name co-occurring with an event word, a road name, a route name, and an article including a specific region related word are displayed. That is, not only the geographical name but also various types of articles related to the region are displayed together with the map. Therefore, the convenience of the user who is the map viewer is improved.

As described above, according to this embodiment, it is possible to obtain the same effect as that of the first embodiment.
In particular, according to the present embodiment, when the article including the first region-related word includes a predetermined event word, the level of detail corresponding to the first region-related word is given. It is possible to perform control so that information presumed to be useful for a user who browses a map of a region in a range corresponding to a related word is selectively displayed.
In addition, according to the present embodiment, when an article including the second region-related word includes a predetermined event word, in addition to the detail level corresponding to the second region-related word, the detail level having a smaller scale is set. Therefore, in the mobile terminal device 10, not only a user who browses a map of a region in a range corresponding to the second region-related word but also a map in a wider range than a region map in the range corresponding to the second region-related word. It is possible to perform control so that information presumed to be useful also to a user who browses is selectively displayed.
Further, according to the present embodiment, since the level of detail corresponding to the third region-related word is given to the article including the third region-related word, the specific region is unambiguously related to the specific region. By storing in the region-related word table TBL32 (first storage unit) the word to be recalled as the third region-related word, the user of the mobile terminal device 10 browses a map in a range corresponding to a specific region. It is possible to control so that information presumed to be useful is selectively displayed.

<Modification of Second Embodiment>
The present invention is not limited to the second embodiment described above, and the following modifications are possible. Moreover, each modification can be combined suitably.
(1) In the second embodiment, the level of detail corresponding to the second area-related word is given to the article regardless of whether or not the article including the second area-related word includes an event word. Only when an article containing two region-related words includes an event word, a detail level corresponding to the second region-related word is assigned to the article, and a detail level with a smaller scale than the assigned detail level is given. You may make it do.
In this case, when it is determined in step S23 of FIG. 15 that the article includes the second region-related word, the CPU 31B subsequently determines whether or not the article includes the event word and includes the event word. Gives a level of detail corresponding to the second region-related word. Next, when there is a detail level corresponding to a scale smaller than the detail level scale corresponding to the second region-related word, the CPU 31B is small in addition to the detail level corresponding to the second region-related word. Give the article a level of detail corresponding to the scale.
According to this modification, since the level of detail is given only to articles in which the second region-related word and the predetermined event word co-occur, only articles including the predetermined event word among the articles including the geographical name are given. Is displayed. Therefore, compared with the said embodiment, it becomes possible to control so that the articles estimated to be particularly useful among the articles to be displayed are displayed on the mobile terminal device 10.
(2) In the second embodiment, it is determined whether the region-related word included in the article corresponds to one of the first region-related word, the second region-related word, or the third region-related word. You may make it determine whether it corresponds to at least 1 of a 1 area related word, a 2nd area related word, and a 3rd area related word.

<Third Embodiment>
Next, a third embodiment of the present invention will be described.
In the first embodiment, the level of detail corresponding to the region-related word is assigned to the article including the region-related word. However, in the third embodiment, the source account of the article is set to one of a plurality of levels of detail. A table stored in correspondence is prepared in advance, and a level of detail according to the sender account is assigned.
In the following description, common reference numerals are used for elements common to the first embodiment, and description thereof is omitted as appropriate.

  FIG. 16 is a block diagram showing a functional configuration of a blog map providing server (display control device) 30C according to the present embodiment. The blog map providing server 30C is different from the blog map providing server 30 according to the first embodiment in that the storage device 34c (storage unit, second storage unit) includes an account table TBL33 instead of the region-related word dictionary ST31. Is different.

  FIG. 17 is a diagram showing an example of the contents stored in the account table TBL33. As shown in the figure, the account table TBL33 stores account names belonging to three types of “region (wide area)”, “prefecture”, and “city”, and the level of detail for each type. Is assigned. In the present embodiment, the level of detail “1” is in the scale range “less than 1 / 350,000”, and the level of detail “2” is in the range “1 / 350,000 to less than 1 / 24,000”. The level of detail “3” is set for “above”.

Accounts belonging to “local” are accounts of local or regional TV stations, radio stations, tourism associations, and travel information sites. Accounts belonging to “prefectures” are official accounts of prefectural offices, This is an account for TV stations, radio stations, tourism associations and travel information sites. Accounts belonging to “municipalities” are official accounts of municipal offices or accounts of tourism associations.
As described above, the storage device 34c functions as a storage unit or a second storage unit that stores an article source account in association with any of the plurality of detail levels.
Here, in the case where the source account of the article is related to a region, it is assumed that the article transmitted from the account includes a lot of information regarding the region related to the account. Therefore, in the present embodiment, according to the region to which the sender account is associated, the detail level is stored in advance in association with each sender account, and the detail level corresponding to the sender account of the article is stored in the article. It is trying to grant.

FIG. 18 is a flowchart of the grant process according to this embodiment, and shows a detailed flow of the grant process (Sb7) in FIG.
First, for the article newly stored in the article table TBL31 in step Sb1 (FIG. 7), the CPU 31 acquires the account name of the article originator account from the article table TBL31, and the account name is stored in the account table TBL33. It is determined whether it matches any of the account names (S31). If the determination result is YES, the CPU 31 gives the article the level of detail stored in association with the matching account name (S32).
Thus, CPU31 respond | corresponds to a sender account to the article in which the sender account is memorize | stored in the memory | storage device 34c (memory | storage part or 2nd memory | storage part) among the some articles which the article acquisition part 31a acquired. It functions as a granting unit 31b that gives a level of detail.

In steps Sb3 and Sb4 in FIG. 7, in accordance with a display request from the mobile terminal device 10, a level of detail corresponding to a scale is given among articles belonging to a predetermined scale or a display range corresponding to a specified scale. The article of the sender account that has been displayed is displayed. That is, if it is the article of the sender account provided with the level of detail according to the scale, the article text is displayed even when the article text does not include a geographical name or other region-related words.
As described above, the CPU 31 has an article that belongs to the range of the map displayed on the mobile terminal device 10 and is given an article with a level of detail corresponding to the scale of the map displayed on the mobile terminal device 10. 10 functions as a transmission unit 31 c that transmits article information to the mobile terminal device 10.

  According to this embodiment, the same effect as the first embodiment can be obtained. Furthermore, according to the present embodiment, since the level of detail corresponding to the source account of the article is given, there is no need to perform morphological analysis on the article text, and the processing load of the blog map providing server 30C is reduced. is there.

<Modification of Third Embodiment>
(1) In the third embodiment, a level of detail corresponding to the sender account of the article is given, but the profile text of the sender account is subjected to morphological analysis, and the region related words are included in the profile text. In such a case, in addition to the level of detail according to the sender account, a level of detail according to the region-related words included in the text of the profile may be given. Here, the profile is text describing information for introducing the account by the user of the account, and can be arbitrarily edited by the user. For example, the account name of the “A-region travel information editing department” may include the town name of a hot spring resort that is famous in the A-region. Articles transmitted with such an account are presumed to be useful for users who browse a map (enlarged view) of an area in a range corresponding to a large scale.
In this modification, the storage device 34c stores an area related word dictionary in addition to the article table TBL31 and the account table TBL33. The region-related word dictionary is the same as that described in the first embodiment. However, a wide-area dictionary is stored in association with the detail level “1” (scale range “less than 1 / 350,000”), and the detail level “2” (“1 / 350,000 or more and less than 1 / 24,000”). The prefecture dictionary and the area dictionary are stored in association with the municipality dictionary at the detail level “3” (“1 / 24,000 or more”). Further, the region-related word dictionary of this modification does not include a spot dictionary.

  FIG. 19 is a flowchart showing the flow of the grant process according to this modification. As shown in the figure, in step S32, the CPU 31 assigns a detail level corresponding to the sender account to the article, and then morphologically analyzes the profile of the sender account (S33). If the profile includes any of the region-related words stored in the region-related word dictionary (S34: YES), the level of detail stored corresponding to the region-related word in the region-related word dictionary Is added to the article and stored in the article table TBL31 (S35). Next, in step S36, it is determined whether or not an undetermined area-related word is included in the profile subjected to morphological analysis in step S33 (S36). When the determination result is YES, the level of detail corresponding to the undetermined area-related word is given to the article (S35). If the determination result of step S36 is NO, that is, if there is no undetermined area-related word, the grant process ends.

  According to this modification, in addition to the level of detail corresponding to the source account of the article, the level of detail corresponding to the region-related words included in the profile of the source account is given, so the source account It is possible to associate the level of detail suitable for the articles in various regions in the transmission with the articles.

(2) The third embodiment and the modification example (1) can be appropriately combined with the first embodiment or the second embodiment. That is, in the grant process, the grant process (FIG. 8) according to the first embodiment may be executed after the grant process (FIG. 18 or FIG. 19) according to the third embodiment is executed. Moreover, after performing the provision process (FIG. 18 or FIG. 19) which concerns on 3rd Embodiment, you may perform the provision process (FIG. 15) which concerns on 2nd Embodiment.
In any case, the correspondence relationship between the level of detail and the scale in the third embodiment and the modified example (1) may be as shown in FIG. 6A. Therefore, in the account table TBL33, an account belonging to “Region” is assigned a detail level “1” (scale range “less than 1 / 350,000”), and an account belonging to “Prefecture” is assigned a detail level “2”. (Scale range “1 / 350,000 or more and less than 1 / 70,000”), and account belonging to “City” has a detail level of “4” (scale range “1 / 24,000 or more and less than 1 / 8,000”) assign. And in the modification (1), the same area related word dictionary as the area related word dictionary ST31 is used.

<Modification of the first to third embodiments>
The present invention is not limited to the first to third embodiments described above, and the following modifications are possible. Moreover, each modification can be combined suitably.
(1) In the first to third embodiments, the transmission unit 31c displays an article to which the level of detail according to the scale of the map to be displayed is displayed on the mobile terminal device 10, but is displayed. A certain number of articles with a high score among articles with a level of detail corresponding to a scale larger than the scale of the map to be displayed together with articles with a level of detail according to the scale of the map to be displayed Articles may be displayed. That is, a part of an article to be displayed on a map (for example, a map of a region equivalent to a district) having a larger enlargement ratio than a map to be displayed (for example, a map of a region corresponding to a prefecture) is displayed. It may be. Hereinafter, with reference to FIG. 20 to FIG. 24, a case where the present modification is applied to the first embodiment will be described.

  FIG. 20 is a block diagram showing a functional configuration of a blog map providing server (display control device) 30D according to the present embodiment. The blog map providing server 30D includes the blog map providing server according to the first embodiment in that the CPU 31D further includes a score calculation unit 31e, and the storage device 34c includes an article table TBL34 instead of the article table TBL31. 30.

The score calculation unit 31e calculates, for each article to which the detail level is given by the grant unit 31c, a score that increases as the scale corresponding to the detail level given by the grant unit 31c is small and the importance is high. To do.
Specifically, the score calculation unit 31e calculates the score S of the article based on the following formula A.
S = (1 / L) × w (formula A)
Here, L is the level of detail and w is the importance of the article. Here, the importance level indicates the degree to which an article is estimated to be important for a viewer. In this variation, the importance is calculated based on the number of retweets. As described above, articles with more retweets are articles that attract attention from users of the blog service. Therefore, Formula A is set such that the greater the number of retweets, the higher the importance w and the higher the score.
Further, for example, when a map of the A region corresponding to the detail level “1” is displayed, the displayed map is displayed rather than the article related to the spot corresponding to the detail level “5”. It is desirable to display an article with a detail level closer to the detail level “1”. Therefore, in Formula A, the smaller the scale corresponding to the level of detail given by the granting unit 31c (that is, the smaller the level of detail level “1” to “5”), the higher the score value. Is set.
Therefore, if the article has the same importance level w, the article at the level of detail corresponding to the small scale has a higher score than the article at the level of detail corresponding to the large scale. Also, if the level of detail is the same, an article with a higher importance w has a higher score.

  FIG. 21 is a diagram showing an example of the contents stored in the article table TBL34 according to this modification. As shown in FIG. 21, in the article table TBL34 of the present embodiment, each article provided from the blog server 20 is associated with the ID of each article, the posting time (transmission time), the latitude / longitude information, the article The sender account name, article text, retweet count (“RT count”), level of detail, and score are stored.

  FIG. 22 is a sequence chart showing an overall operation flow according to this modification. The sequence chart shown in the figure is different from the sequence chart shown in FIG. 7 according to the first embodiment in that it has a score calculation process (Sc3). As illustrated in FIG. 21, the CPU 31D of the blog map providing server 30 executes the score calculation process (Sc3) after executing the assignment process (Sb2) for the article newly stored in the article table TBL34. Specifically, the level of detail and the number of retweets given in the grant process are read from the article table TBL34, the score S is calculated based on the formula A, and stored in the article table TBL34.

Subsequently, when receiving a display request from the mobile terminal device 10, the CPU 31D executes a transmission process of transmitting an article of a scale corresponding to a predetermined zoom level to the mobile terminal device 10 (Sc3). FIG. 23 is a flowchart of a transmission process according to this modification. As shown in the figure, first, the CPU 31D specifies a map range corresponding to a scale corresponding to a predetermined zoom level as a display range, which is a map area including position information included in the display request, Of the articles having latitude / longitude information belonging to the display range, an article having a level of detail corresponding to the scale of the map displayed on the mobile terminal device 10 is read from the article table TBL34 (S41). Subsequently, the CPU 31D determines whether or not there is a level of detail having a scale larger than the scale of the displayed map (S42). When this determination result is YES, the CPU 31D reads out a predetermined number of articles with high scores from the article table TBL34, among the articles having the latitude and longitude information belonging to the display range and having a high level of detail (S43). ), Information on a predetermined number of articles having a high score is transmitted to the mobile terminal device 10 so as to be displayed on the mobile terminal device 10 together with the information on the article read in step S42 (S44).
On the other hand, if it is determined in step S42 that there is no level of detail that is larger than the scale of the displayed map, the CPU 31D displays the article information read in step S42 on the mobile terminal device 10. It transmits to the portable terminal device 10 (S44).
As described above, the CPU 31D (transmission unit 31c) calculates the score calculation unit 31e among the articles that belong to the range of the displayed map and are given a level of detail corresponding to a scale larger than the scale of the map. The degree of detail corresponding to the scale of the displayed map is displayed so that a predetermined number of articles with a high score are displayed on the mobile terminal device 10 together with the article with the level of detail corresponding to the scale of the displayed map. The information of the article to which the level is given and the predetermined number of articles are transmitted.

  In the present modification, the CPU 31D reads from the article table TBL34 the article having the level of detail level “4” corresponding to the map scale in step S41. Next, since there is a detail level “5” whose scale is larger than the detail level “4” (S42: YES), the CPU 31D has a higher score among articles given the detail level “5”. A predetermined number of articles (predetermined number = 1) are read from the article table TBL34, and articles with the highest level of detail “4” and articles with the highest level of detail “5” are displayed on the timeline together with the map image. Such a blog map page is generated and transmitted to the mobile terminal device 10.

  By the way, as described above, when the scale of the map is small (that is, when the map is in a wide area display) and the number of articles in the display range is large, the density of articles displayed in the limited display area 12a is excessive. Therefore, there is a problem of lack of visibility. For this reason, in the said 1st-3rd embodiment, the article relevant to the area suitable for the display range of the map determined according to the scale of a map is selected, and these articles are displayed on the portable terminal device 10. By configuring, visibility is improved particularly when a wide-area map with a small scale is displayed. However, even if a map with a small scale is displayed on the mobile terminal device 10, an article (which is worth displaying) among articles at a level of detail corresponding to a scale larger than the scale of the displayed map ( That is, it is assumed that articles with high importance) are included. Therefore, in this modification, when there is a level of detail corresponding to a scale larger than the scale corresponding to the scale of the displayed map, the score is high among articles of the level of detail corresponding to the large scale. A predetermined number of articles are displayed. When there are a plurality of detail levels corresponding to a scale larger than the scale corresponding to the scale of the displayed map, a predetermined number of articles having a high score among all the articles assigned with the plurality of detail levels. indicate. Note that instead of a predetermined number of articles having a high score, articles having a score higher than a threshold value may be displayed.

In FIG. 22, when receiving the blog map page from the blog map providing server 30, the mobile terminal device 10 displays the blog map page in the display area 12a of the touch panel 12 (Sa1). FIG. 24 is a display example according to this modification. In the illustrated example, a scale map corresponding to the detail level “4” is displayed, and the article B1 of the detail level “4” (city) corresponding to the scale of the map is displayed in the article timeline. , B2 and B4, and an article B3 with a detail level “5” having a scale larger than the detail level “4” are displayed. In addition to the timeline display, a balloon image including the article text is displayed at a position on the map corresponding to the latitude and longitude information of the article.
In step Sa <b> 2, when receiving an instruction to change the zoom level, the mobile terminal device 10 transmits a display request including designation information for designating the zoom level after the change to the blog map providing server 30. In response to receiving the display request, the blog map providing server 30 executes a transmission process (Sb4) for transmitting the information of the article at a scale corresponding to the designated zoom level to the mobile terminal device 10.

  As described above, according to this modification, in addition to the articles at the level of detail corresponding to the scale of the displayed map, among the articles given the level of detail corresponding to the scale larger than the scale of the displayed map Since articles with smaller scales and higher importance are displayed, the degree of detail corresponding to the scale closer to the scale of the displayed map among articles that are not displayed when the map is displayed in a wide area Articles of a level that are estimated to be highly useful for the user who is a viewer can be additionally displayed.

(2) In the first embodiment and the modification example (1), the region-related word dictionary ST31 is stored in the storage device 34c of the blog map providing server 30, but is connected to the network MN and communicates with the blog map providing server 30. The region-related word dictionary ST31 may be stored in a storage device of a possible server device (external device). Similarly, in the second embodiment, the region-related word table TBL32 and the event word dictionary ST32 may be stored in the storage device of the external device. In these cases, the storage device of the external device functions as the first storage unit. In the third embodiment, the account table TBL33 may be stored in a storage device of an external device. In this case, the storage device of the external device functions as the second storage unit or the storage unit. In this case, the providing process (FIGS. 8, 15, 18, and 19) in each of the above embodiments and modifications is executed with reference to the storage device of the external device.

(3) In the first to third embodiments and the modifications described above, the blog map providing servers 30, 30B, 30C, and 30D execute the function of the display control device according to the present invention. The touch panel 12 (display device) may display an article with a level of detail according to the scale of the map.
(4) In the first to third embodiments described above, the latitude / longitude information of each article is determined based on both the latitude / longitude information indicated by the geotag and the latitude / longitude information of the place name derived by analyzing the body text. However, either one may be used.

(5) In the first to second embodiments and the modification example (1) described above, the level of detail is “1” to “5”, and in the third embodiment, the level of detail is “1” to “3”. However, the present invention is not limited to this and may be set arbitrarily. In the first to third embodiments and the modification example (1) described above, the level of detail level “1” to “5” (or “1” to “3”) is a numerical value of the level of detail as the scale is smaller. However, the numerical value of the level of detail may be increased as the scale is reduced. That is, the detail level corresponding to the smallest scale range may be “5” (or “3”), and the detail level corresponding to the largest scale range may be “1”. In this case, the score S is obtained based on the following formula A ′.
S = L × w (formula A ′)
Note that the calculation formula for the score S is not limited to the formula A or the formula A ′, and may be set such that the smaller the scale and the higher the importance, the smaller the score value. Moreover, although the number of retweets is shown as the importance w, the importance may be calculated using any other index. For example, you may use the parameter | index which shows the adaptation degree to the attention word used frequently by recent articles, such as the number of HOT keywords contained in an article. In this case, the score increases as the number of HOT keywords increases. In addition, the mention “@” that is frequently used in articles such as microblogs is considered to be less important because it is simply mentioned by mentioning the name of another user in the article text. . Therefore, the importance may be set so that the article including the mention “@” has a low score.

(6) In the above-described first to third embodiments and modifications, the description has been made taking articles such as blogs and microblogs as examples, but the present invention is not limited thereto. For example, an article related to a spot or area obtained by crawling the website of the Japan Meteorological Agency or a newspaper company is assigned a level of detail according to the region-related word, and the degree of detail according to the scale of the displayed map You may make it display the article of the level with the map. In this case, as the transmission time of the article, the crawled date / time, the updated date / time of the article, and the date / time of the article described in the article text may be used. As latitude / longitude information, the latitude / longitude of an arbitrary point such as the latitude / longitude of a spot included in the article text or the latitude / longitude of a representative point (for example, the prefectural office address) of the geographical name included in the article may be used. That's fine.
(7) In the first to third embodiments and the modifications described above, the terminal used when the user browses the map is the mobile terminal device 10, but is not limited thereto, and is a stationary personal computer device. Also good. Moreover, it is not necessary to have a touch panel, and the display unit and the operation unit may be configured separately. The mobile terminal device 10 only needs to have a communication function, and does not need to have a telephone function.
