That is, the determination unit 12 determines the circle centered on each search start point and destination as the search range. The search range is not necessarily limited to a perfect circular range, and may be a polygonal range or an elliptical range. Further, it is assumed that each search range has a different width depending on the distance from the current position. In the example shown in FIG. 9B, the search range is wider as the distance from the current position is longer and narrower as the distance from the current position is shorter. In addition, in the examples of FIGS. 9B and 10 and after, the description of the search starting point is omitted except for a part.

For example, it is assumed that a person will drop in at a spot for a meal or a break when heading to a destination, but it is unlikely that he / she will stop at a spot far from the route in an area near the current position. Therefore, the determination unit 12 determines a narrower range as the search range as the distance from the current position is shorter. In other words, in the case of the first example, it can be said that the search system of the present embodiment dynamically changes the search range as the moving body moves. For example, in the search device of the present embodiment, the search range may change with time. That is, in the search system, the search range may change depending on the distance and time.

FIG. 10 is a diagram showing a second example of the search range. In the second example shown in FIG. 10, the first search range 85-1 to the sixth search range 85-6 are the same as those in the first example shown in FIG. 9B, and each search range is the distance from the current position. The longer it is, the wider it is, and the shorter the distance from the current position, the narrower it is. In the second example, in the seventh search range 85-7, the area beyond the destination with respect to the current position is excluded from the search range. That is, the determination unit 12 excludes the area beyond the destination from the search range. This is because it is unlikely that the user will drop in at a spot in an area beyond the destination.

FIG. 11 is a diagram showing a third example of the search range. In the third example shown in FIG. 11, the search range (first search range 85-1 to fourth search range 85-4) between the current position and a predetermined distance is the same as the examples shown in FIGS. 9 and 10. Yes, the longer the distance from the current position, the wider, and the shorter the distance from the current position, the narrower. In the third example, the search range (8th search range 85-8) from the predetermined position (4th search starting point 84-4) to the destination is a band-shaped range having a certain width. That is, the determination unit 12 determines the search range so as not to increase the search range from the predetermined position to the destination. This is because it is unlikely that a person who stops at a spot and heads for the destination will stop at a spot far from the route.

FIG. 12 is a diagram showing a fourth example of the search range. In the fourth example shown in FIG. 12, the first search range 85-1 to the fourth search range 85-4 are the same as the examples shown in FIGS. 9 to 11, and each search range is the distance from the current position. The longer it is, the wider it is, and the shorter the distance from the current position, the narrower it is. In the fourth example, the search range (9th search range 85-9) from the predetermined position (4th search start point 84-4) to the destination is narrower as the distance from the current position is longer, and is from the current position. The shorter the distance, the wider. That is, the search range in the fourth example is wider in the region from the current position to the predetermined position as the distance from the current position is longer, narrower as the distance from the current position is shorter, and is narrower in the region from the predetermined position to the destination. , The longer the distance from the current position, the narrower, and the shorter the distance from the current position, the wider. This is because it is unlikely that you will drop in at a spot in an area close to your destination.

FIG. 13 is a diagram showing a fifth example of the search range. In the fifth example shown in FIG. 13, the circular tenth search range 85-10 centered on the search starting point, the eleventh search range 85-11, and the circular twelfth search range 85-12 centered on the destination exist. Further, the tangents of the thirteenth search range 85-13, the eleventh search range 85-11, and the twelfth search range 85-12 are framed by the tangents of the tenth search range 85-10 and the eleventh search range 85-11. There is a 14th search range 85-14. By applying the fifth example, the server 1 can determine an appropriate search range even when the positions of the circular search ranges centered on the search start point and the destination are separated from each other. In other words, in the case of the fifth example, the search device of the present embodiment continuously changes the search range with the movement of the moving body. In the case of the fifth example, it can be said that the search device of the present embodiment dynamically changes the search range as the moving body moves.

FIG. 14 is a diagram showing a sixth example of the search range. In the sixth example shown in FIG. 14, the circular tenth search range 85-10 centered on the search starting point, the eleventh search range 85-11, and the circular twelfth search range 85-12 centered on the destination are , The same as the example of FIG. In the sixth example, there is a band-shaped 15th search range 85-15 between the circular 10th search range 85-10 and the 11th search range 85-11. The width of the 15th search range 85-15 is the smaller of the diameters of the search ranges (10th search range 85-10, 11th search range 85-11) at both ends of the 13th search range 85-13 (10th search range). It is assumed that it is the same as the range 85-10). Similarly, the width of the strip-shaped 16th search range 85-16 existing between the circular 11th search range 85-11 and the 12th search range 85-12 is the search range at both ends (11th search range 85-). 11. It is assumed that the diameter of the 12th search range 85-12) is the same as the smaller diameter (11th search range 85-11). In other words, in the case of the sixth example, the search device of the present embodiment intermittently changes the search range with the movement of the moving body. In the case of the sixth example, it can be said that the search device of the present embodiment dynamically changes the search range as the moving body moves.

By applying the sixth example, the server 1 determines an appropriate search range even when the positions of the search ranges centered on the search start point and the destination are separated from each other, as in the fifth example. be able to. In the sixth example, since the search range is narrower than in the fifth example, the search processing time can be shortened and the amount of communication when transmitting spot information can be reduced.

The user may be able to set which search range of the first to sixth examples is applied from the navigation device 3. Then, the second transmission unit 32 may transmit the setting of which search range of the first example to the sixth example is applied to the server 1. The determination unit 12 of the server 1 applies the setting of any one of the first example to the sixth example according to the setting. Further, the determination unit 12 may determine a search range in which the first example to the sixth example are combined. For example, the determination unit 12 may exclude the area beyond the destination from the search range in the third example, the fifth example, and the sixth example as in the second example.

FIG. 15 is a diagram showing a seventh example of the search range. In the seventh example, the seventh search starting point 84-7 is an IC (interchange) set as the entrance of the expressway 86, and the eighth search starting point 84-8 is set as the exit of the expressway 86. It is assumed that it is an IC. That is, the navigation device 3 sets a route to the destination through the expressway 86 between the 7th search starting point 84-7 and the 8th search starting point 84-8. In this case, it is unlikely that you will get off the highway on the way and stop at the spot. Therefore, the determination unit 12 restricts the placement of the search range around the expressway among the set routes.

The 17th search range 85-17 to the 18th search range 85-18 from the current position to the entrance of the expressway is wider as the distance from the current position is longer and narrower as the distance from the current position is shorter. The 20th search range 85-20 to the 22nd search range 85-22 from the exit of the expressway to the destination is wider as the distance from the exit of the expressway is longer, and the shorter the distance from the current position. narrow. That is, it is the same as the first example shown in FIG. In the seventh example, the same search range as in the second to sixth examples is applied to the search range from the current position to the entrance of the expressway and the search range from the exit of the expressway to the destination. May be good.

As described above, when the seventh example is applied, the server 1 can appropriately determine the search range when the route includes an expressway.

In the present embodiment, the number of spots of the search result presented to the user is increased, and there is no need to bother when selecting the stop-by spots, for example, the existing spots are included in the direction opposite to the traveling direction. In the present embodiment, it is possible to improve the efficiency of processing when providing information on spots around the route.

16 and 17 are sequence diagrams showing an example of the processing of the present embodiment. The second transmission unit 32 of the navigation device 3 responds to the user's operation from the current position of the moving body on which the navigation device 3 is mounted, the position of the destination of the moving body, and the current position of the moving body to the position of the destination. A spot transmission request is transmitted to the server 1 together with information regarding the route of (S101). Instead of responding to the user's operation, the second transmission unit 32 of the navigation device 3 periodically sets the target from the current position of the moving body on which the navigation device 3 is mounted, the position of the destination of the moving body, and the current position of the moving body. A spot transmission request may be transmitted to the server 1 together with information on the route to the location of the ground. The spot transmission request may be a recommendation spot transmission request. The information about the route includes the coordinates of a plurality of search origins and the number of search origins.

The determination unit 12 of the server 1 has a different width depending on the distance from the current position based on the received current position of the moving body and the information about the route from the current position of the moving body to the position of the destination. A plurality of search ranges in the vicinity are determined (S102). The search unit 13 transmits an inquiry including a search condition to the data server 2 (S103). Then, the search unit 13 receives the spot information according to the search conditions from the data server 2 (S104). The search unit 13 searches for a spot existing in the search range by the processing of S103 and S104. The search unit 13 repeats the processes of S103 and S104 for each search starting point (for each search range).

When the first transmission unit 14 receives the recommendation spot transmission request from the navigation device 3, the first transmission unit 14 transmits the recommendation spot provision request to the recommendation server 4 together with the searched spot information, the user ID, and the number of spot return requests. (S105). The extraction unit 42 of the recommendation server 4 is searched from the spots searched in advance based on the favorite spots for each user stored in the third storage unit 44, the spots selected by the user, or the spots that the user has visited. The recommended spot is extracted (S106). The third transmission unit 43 transmits the information of the recommendation spot extracted by the extraction unit 42 to the server 1 (S107).

The first transmission unit 14 of the server 1 transmits the spot information or the recommendation spot information transmitted from the recommendation server 4 to the navigation device 3 (S108). When the processing of S105 to S107 is not performed, the first transmission unit 14 transmits the information of the spot searched by the search unit 13 to the navigation device 3, and when the processing of S105 to S107 is performed, the first transmission unit 14 , The information of the recommendation spot extracted by the recommendation server 4 is transmitted to the navigation device 3. When the recommended spot information is transmitted, the spot information in the following description is replaced with the recommended spot information.

In FIG. 17, the deduplication unit 34 of the navigation device 3 removes the duplicated information when the received spot information overlaps with the already received spot information (S109). The direction calculation unit 35 calculates the direction of the spot with respect to the route (S110). The display control unit 36 causes the second display unit 40 to display a list of spots (S111). When a spot in the displayed list is selected by voice or touch operation, the display control unit 36 causes the second display unit 40 to display an explanation screen including the address, explanation, event holding time, etc. of the spot ( S112).

When the spot displayed on the second display unit 40 is selected by the user as the destination or waypoint, the route search unit 37 sets the spot as the destination or waypoint (S113). When the spot displayed on the second display unit 40 is set as the destination or waypoint in S113, the route search unit 37 re-searches the route (S114). For example, when the spot displayed on the second display unit 40 is set as the destination, the route search unit 37 searches for a route from the current position to the spot. Further, when the spot displayed on the second display unit 40 is set as a waypoint, the route search unit 37 searches for a route from the current position to the destination via the spot.

Then, the second transmission unit 32 makes a spot transmission request together with information on the current position of the moving body equipped with the navigation device 3, the position of the destination of the moving body, and the route from the current position of the moving body to the position of the destination. It is transmitted to the server 1 (S115). After the processing of S115, the processing after S102 is executed again using the information transmitted in S115.

As described above, the server 1 determines the search range having a different width according to the distance from the current position, and provides the spot within the search range to the navigation device 3. For example, the search range is set so as not to include a range in which the user is unlikely to stop by because the longer the distance from the current position is, the wider the search range is, and the shorter the distance from the current position is, the narrower the search range is. As a result, the server 1 can shorten the spot search processing time and the data transmission time, and can provide the spot information that the user is likely to stop by. That is, the server 1 can provide the user with more appropriate information on the spots around the route, and can streamline the processing at the time of provision.

<Second embodiment>
As shown in FIG. 18, the system of the second embodiment includes an information display device 5, a server device 6, an external server 8, and a terminal 9. The information display device 5 corresponds to, for example, the navigation device 3 of the first embodiment. Although not shown, the information display device 5 includes, for example, the control unit 30 of the first embodiment. The server device 6 corresponds to, for example, the server 1, the data server 2, and the recommendation server 4 of the first embodiment. The server device 6, the information display device 5, the external server 8, and the terminal 9 are connected to, for example, the network 7. The network 7 includes, for example, the Internet or a public communication network. For example, the terminal 9 connects to the network 7 via a radio base station and a relay device. The terminal 9 can communicate with the external server 8 via the network 7. The server device 6 can communicate with the information display device 5 and the external server 8 via the network 7, for example.

The external server 8 is, for example, a server that provides a social networking service (SNS). Examples of the SNS include Twitter (registered trademark), FACEBOOK (registered trademark), INSTAGRAM (registered trademark), YouTube (registered trademark), and LINE (registered trademark). SNS may be interpreted in a broad sense and may include a blog or an electronic bulletin board. In SNS, for example, post information posted by a user is posted.

The terminal 9 is, for example, an information processing terminal used by a user who posts posted information to an SNS. The terminal 9 is, for example, a smartphone, a mobile phone, a tablet terminal, a personal computer, or a mobile computer. For example, the terminal 9 can access the external server 8 and post the posting information to the SNS by the operation of the user. The posted information includes at least a message. The message may include, for example, the poster's feelings or impressions of the spot. Spots indicate various points and places. Spots include, for example, restaurants, tourist attractions, incidents or accidents, or traffic jams. The terminal 9 may include, for example, a photographing device for photographing an imaged object. The photographing device is, for example, a camera. The posted information may include shooting data. The shooting data shot by the shooting device may include, for example, a still image or a moving image.

The terminal 9 may include, for example, a positioning sensor for positioning the position. The terminal 9 can add metadata to a still image or a moving image posted to the SNS by using the positioning sensor. Examples of the positioning sensor include a GPS (Global Positioning System) sensor. Further, the terminal 9 may acquire the position information indicating the position of the terminal 9 by using the base stations of a plurality of mobile phones. The position information is represented by, for example, latitude and longitude. The metadata is an example of shooting position information. The shooting position information is information indicating a position where a still image or a moving image is shot. The position of the spot to be posted on the SNS may be specified, for example, by using the metadata contained in the captured still image or moving image. Further, the metadata may include information on the shooting time taken by the shooting device. The terminal 9 provides a message or posted information including the message and shooting data to the external server 8 via the network 7.

The information display device 5 includes, for example, an image display device 57. The image display device 57 can function as, for example, the first display unit 39 and the second display unit 40 of the first embodiment. The image display device 57 is configured so that, for example, a map can be displayed. The information display device 5 is held by, for example, a moving body. The moving body is, for example, a vehicle. Vehicles include, for example, automobiles, motorcycles, bicycles, and snowmobiles. The information display device 5 is, for example, a navigation device mounted on a vehicle. Further, the moving body in which the information display device 5 is held may be a person. In other words, the information display device 5 may be an information processing terminal held by a person. The information display device 5 is not limited to the navigation device. The information display device 5 may be, for example, a smartphone, a tablet terminal, and a mobile computer.

The information display device 5 may include, for example, a positioning sensor different from the positioning sensor of the terminal 9. Examples of the positioning sensor of the information display device 5 include a GPS sensor. The terminal 9 uses the positioning sensor of the information display device 5 to acquire the position information of the current location of the information display device 5. The location information is associated with, for example, a predetermined text tag. When the information display device 5 makes a provision request to the server device 6, for example, the information display device 5 transmits the position information of the current location.

The server device 6 collects the posted information posted to the SNS from the external server 8, for example. The server device 6 analyzes the posted information and generates the analysis information. The analysis information is, for example, vector information obtained by analyzing and vectorizing the posted information posted on the SNS. The server device 6 identifies the spot position information based on the posted information posted on the SNS. The spot position information is information indicating the position of the spot. The spot position information is, for example, the coordinates where the spot exists.

The server device 6 generates spot information by associating the generated analysis information with the specified spot position information.

Spot information is information about a specific place. The spot information is, for example, POI (Point Of Interest). A POI is, for example, information about a place that someone finds useful or interested in. By generating spot information from the posted information posted on the SNS, the server device 6 can reflect the hot spot information that is exciting in the world in the spot information in real time.

In other words, the server device 6 can dynamically provide the user with fresh spot information according to the region or the time of year. Since the spot information generated from the posted information posted on the SNS can dynamically provide the information, it may be called a dynamic POI in one example. Dynamic POI means information that changes dynamically in a relatively short time, for example, monthly, weekly, daily, hourly, or minutely. The server device 6 can also manage the dynamic POI for each time by managing the collected posted information for each predetermined time zone, for example.

For example, the server device 6 provides the analysis information included in the spot information to the information display device 5 in response to the provision request from the information display device 5. For example, the server device 6 may search for spot information around the current location of the information display device 5 based on the position information of the current location transmitted from the information display device 5. The server device 6 provides the information display device 5 with analysis information included in the spot information around the current location of the information display device 5 found by the search. The spot information around the current location is information indicating an example of spot information that satisfies a predetermined condition with respect to the position indicated by the position information. The provision request is, for example, information requesting the provision of analysis information included in the spot information satisfying a predetermined condition with respect to the position indicated by the position information of the information display device 5.

Further, the server device 6 may search for spot position information around the route from the current location to the destination in response to the provision request from the information display device 5, for example. For example, the server device 6 may provide the information display device 5 with analysis information corresponding to spot information around the route from the current location to the destination of the information display device 5 found by the search. For example, the server device 6 may provide the information display device 5 with analysis information corresponding to spot information existing at a predetermined distance or less from the route from the current location to the destination of the information display device 5 found by the search. The server device 6 may transmit, for example, analysis information corresponding to spot information existing at a predetermined distance or less from the route from the current location to the destination of the information display device 5 found on the route to the information display device 5. The spot information existing at a predetermined distance or less from the route from the current location to the destination is information indicating an example of spot information satisfying a predetermined condition with respect to the position indicated by the position information. Similar to the first embodiment, the server device 6 may transmit the analysis information in the search range illustrated in FIGS. 9 to 15 to the information display device 5 on the route from the current location to the destination.

The information display device 5 can display the analysis information included in the spot information provided by the server device 6 on the image display device 57. For example, the information display device 5 can superimpose and display the analysis information included in the spot information around the current location on the map. Further, the information display device 5 can display, for example, the analysis information included in the spot information existing at a predetermined distance or less from the route from the current location of the information display device 5 to the destination on the map. The information display device 5 can superimpose and display the analysis information in the search range illustrated in FIGS. 9 to 15 on the map in the route from the current location to the destination.

By the way, a user may operate a terminal 9 to post, for example, a message regarding a spot feature to an SNS provided by an external server 8. The message is an example of posted information posted on SNS. The message regarding the characteristics of the spot is, for example, a message including the poster's feelings toward the spot. When a message representing the emotion of the poster is posted, the server device 6 collects the posted information expressing the emotion from the external server 8, analyzes the collected posted information, and generates analysis information. The server device 6 can generate spot information including analysis information about emotions from the generated analysis information and provide it to the information display device 5.

However, the posted information regarding the characteristics of the spot is posted in chronological order regardless of the position of the spot. Even if the message is posted to the SNS regardless of the spot location, the user may want to see the posted information at the actual spot location. When it is desired to confirm the posted information at the position of the spot, the user of the information display device 5 may need to search again using, for example, the name of the spot as a keyword.

When the server device 6 of the present embodiment receives a request for providing analysis information from the information display device 5, for example, the server device 6 provides the information display device 5 with spot information of a spot near the current location of the information display device 5. The information display device 5 superimposes and displays the analysis information included in the spot information provided by the server device 6 on the map. The analysis information includes, for example, the feelings of the poster at the spot. Therefore, the information display device 5 can inform the emotions of other users toward the spot. The server device 6 extracts, for example, spot information including shooting information of a still image or a moving image from the spot information corresponding to the spot. Then, the server device 6 may provide the extracted spot information to the information display device 5.

Hereinafter, the information processing system 20 according to the present embodiment will be described in more detail.

The information processing system 20 includes, for example, a server device 6 and an information display device 5 as shown in FIG.

The server device 6 includes, for example, a control device 62, a communication device 63, and a storage device 64.

The control device 62 controls, for example, the communication device 63. The control device 62 controls, for example, the communication device 63 and connects to the network 7. The control device 62 may control the communication device 63 so that data can be transmitted / received to / from the information display device 5 or the external server 8, for example.

The control device 62 controls the communication device 63 to receive, for example, a spot search request requesting a search for a predetermined spot from the information display device 5. The spot search request includes, for example, information on the current location, destination, and route from the current location to the destination of the moving body including the information display device 5. The control device 62 searches for a peripheral spot along the route from the current location to the destination, for example, in response to a spot search request. By controlling the communication device 63, the control device 62 causes the information display device 5 to transmit, for example, the spot information found by the search.

Further, the control device 62 includes, for example, an analyzer 621, a generation unit 622, and a providing unit 623. The analyzer 621 acquires the posted information posted to the SNS from the external server 8 via, for example, the communication device 63. In SNS, for example, a service that provides posted information posted via API (Application Programming Interface) is provided. The analyzer 621 can acquire the posted information from the external server 8 by using the API, for example.

The analyzer 621 collects a message about a spot posted on the SNS as posted information. The analyzer 621 analyzes the posted information and generates the analysis information. The analyzer 621 may use the compressed information obtained by compressing the posted information posted on the SNS by the user as the analysis information. The compressed information refers to information whose size has been reduced while maintaining the amount of information of the original posted information, for example, by using a compression algorithm. The analyzer 621 may use the vector information obtained by analyzing and vectorizing the posted information posted on the SNS as the analysis information. Vector information can be classified according to, for example, posted information. The classification corresponds to, for example, the emotions of "fun," "delicious," "impressed," "surprised," and "healed." The vector information can be said to be analysis information obtained by analyzing the posted information posted on the SNS.

The analyzer 621 may specify a score that scores the recommendation level of the spot of the posted information posted on the SNS. The score is information obtained by scoring the recommendation level of the spot of the posted information posted on the SNS. The analyzer 621 analyzes, for example, the posted information posted on the SNS for morphological elements to obtain morphemes. The analyzer 621 may use the result of scoring the spot information according to the feature word specified based on the obtained morpheme as a score. The server device 6 can prioritize a plurality of spot information based on the score of the spot information scored by the analyzer 621. For morphological analysis, for example, MeCab can be used.

The analyzer 621 executes, for example, a process of extracting a key phrase from the posted information posted on the SNS. The analyzer 621 executes, for example, a process of extracting a feature word from the posted information posted on the SNS. A feature word is, for example, a term that characterizes a message contained in posted information. Characteristic words include emotional words. The emotional word is a term that expresses the feelings and impressions of the poster who made the post, among the characteristic words. Emotional words include, for example, terms such as happy, sad, and bad. Further, the emotional word may be a symbol such as "..." which expresses the emotion of the poster in the message of the posted information such as "Is Route 43 congested ...". A key phrase is, for example, a characteristic phrase that well expresses the subject of a post. In the key phrase extraction process, the analyzer 621 includes not a "word" meaning a word but a plurality of consecutive words and extracts a "phrase" meaning a phrase.

The analyzer 621 can extract key phrases by using, for example, a dictionary of key phrases created in advance. The analyzer 621 can also use machine learning, for example, to extract key phrases. The analyzer 621 can also extract key phrases on a statistical basis or a graph basis, for example. The analyzer 621 can extract feature words using, for example, a dictionary of feature words created in advance. The analyzer 621 can extract feature words by using, for example, machine learning. The analyzer 621 can also extract feature words on a statistical basis or a graph basis, for example. The analyzer 621 may execute a process of extracting a key phrase and a feature word from the posted information posted on the SNS.

The analyzer 621 may, for example, classify the analysis information generated by analyzing the posted information posted on the SNS into a predetermined category. The analyzer 621 classifies the analyzer 621 into, for example, news, hot springs, parks, museums, shrines, live performances, shopping, amusement, outdoor activities, events, gourmet foods, ramen, and mountains. The category may include any classification. The categories may be classified into appropriate types. The categories may be classified according to the type of emotion. In other words, the analyzer 621 classifies the analysis information into categories according to the type of posted information posted on the SNS.

The analysis information may include, for example, metadata. The metadata is, for example, a text tag containing text data. Text tags are used, for example, to classify analysis information into predetermined categories. In other words, the analysis information is configured so that the posted information can be classified and managed for each category by the text tag. The analyzer 621 is configured so that the message written by the user to the external server 8 can be collected from the external server 8. The analyzer 621 can also be said to be an information acquisition unit that acquires SNS information from the external server 8.

The generation unit 622 generates spot information. As the spot information, analysis information and spot position information are associated with each other. The generation unit 622 stores the generated spot information in the storage device 64.

When the providing unit 623 receives the analysis information provision request from the information display device 5, it controls the communication device 63 to provide the information display device 5 with the analysis information included in the spot information. For example, when the providing unit 623 receives a request for providing spot information from the information display device 5, the providing unit 623 may control the communication device 63 to provide the information display device 5 with the analysis information included in the spot information. For example, when the providing unit 623 receives a request for providing analysis information of a spot belonging to a predetermined category, the providing unit 623 may provide the analysis information of the spot belonging to the requested predetermined category to the information display device 5. In this case, the analysis information requested to be provided is, for example, post information of a predetermined category corresponding to the spot. When there is a plurality of analysis information of spots belonging to a predetermined category, the analyzer 621 may provide the plurality of analysis information to the information display device 5.

The location information is, for example, information indicating the geographical position of the spot. The position information is represented by, for example, latitude and longitude. The position information may include altitude information in addition to latitude and longitude. Time information that specifies latitude and longitude may be added to the position information. The position information acquisition device 55 may acquire position information indicating the position of a point other than the information display device 5. The position information acquisition device 55 may acquire position information indicating a position on a map displayed by the image display device 57, for example. The position on the map may be the center of the map or a specific point on the map.

The device control unit 54 controls, for example, the position information acquisition device 55 to acquire position information indicating the current location of the device control unit 54. The device control unit 54 displays, for example, icon information indicating the current location on the map displayed on the image display device 57 based on the position information acquired from the position information acquisition device 55. This embodiment describes an example in which the position information acquisition device 55 acquires the position information indicating the current location of the moving body on which the information display device 5 is mounted. The present embodiment is not limited to the example in which the position information acquisition device 55 acquires the position information of the moving body.

The device input device 59 is, for example, a device that receives input from the user to the information display device 5. The device input device 59 is, for example, an input key, a button, a keyboard, a pointing device, a microphone, or a touch panel. In the information display device 5, the user inputs a route search instruction to the destination via the device input device 59. In the information display device 5, the route searcher 513 of the device control unit 54 searches for a route from the current location to the destination by using, for example, the Dijkstra method.

The device control unit 54 controls the image display device 57 so that, for example, the searched route from the current location to the destination is superimposed and displayed on the map. For example, when a route search instruction for designating a waypoint is input in addition to the destination via the device input device 59, the device control unit 54 searches for a route via the waypoint by the route searcher 513. The device control unit 54 may request the server device 6 to search for a route from the current location to the destination, and may acquire the route searched from the server device 6. When the server device 6 acquires a route in response to a request for a route search from the device control unit 54, the server device 6 may have the same function as the route search device 513.

The device communication device 56 may transmit a spot search request to the server device 6, for example. The device communication device 56 may receive spot information indicating spots in the vicinity along the route, which is transmitted from the server device 6 in response to the spot search request. The spot search request includes, for example, the current location acquired by the position information acquisition device 55. In addition to the current location, the spot search request may include, for example, a destination or a route from the current location to the destination. The device control unit 54 controls the image display device 57 so that, for example, the analysis information obtained by analyzing the posted information of the spot indicated by the received spot information is displayed on the map.

As described above, in the present embodiment, the spot information is generated based on, for example, a message posted to the SNS provided by the external server 8. For example, when the posted information regarding the feature representing the spot is posted on the SNS provided by the external server 8, the server device 6 analyzes the posted information and identifies the analyzed information. The identified analysis information shows the analysis result of the feature representing the spot. The server 1 generates spot information in which the analysis information and the spot position information specified based on the posted information are associated with each other. The feature representing the spot is, for example, the impression of the poster.

For example, when the device control unit 54 receives the spot information from the server device 6, the device control unit 54 superimposes the spot information on the map and displays it on the image display device 57. For example, when the user selects specific spot information from the plurality of spot information displayed on the image display device 57, the device input device 59 accepts the user's selection. The image display device 57 can display the analysis information of the spot information selected by the user in the device input device 59. The image display device 57 can display an image or video of a spot that is the target of the posted information together with the analysis information. When the number of spot information is one, or when the number is less than or equal to an arbitrarily set number, the image display device 57 does not accept the user's selection of the analysis information included in the spot information provided by the server device 6. It may be displayed in. As the arbitrary number, for example, any number from 1 to 10 can be set.

The spot analysis information is displayed on the map corresponding to the spot position information that satisfies a predetermined condition with respect to the position indicated by the position information. The spot analysis information is displayed on the map, for example, corresponding to the position of the spot information around the current location of the information display device 5. The spot analysis information is displayed, for example, on a map existing at a predetermined distance or less from the route from the current location to the destination of the information display device 5.

Hereinafter, the hardware configuration of the second embodiment will be described. The hardware configuration of the server device 6 is the same as the hardware configuration of the first embodiment shown in FIG.

The device control unit 54, the device output unit 511, the transmission unit 512, and the route searcher 513 are realized, for example, by the processor 111 executing the information processing program expanded in the memory 112 shown in FIG. The device communication device 56 is, for example, the communication interface 114 shown in FIG.

Subsequently, the information stored in the storage device 64 of the server device 6 will be illustrated. The storage device 64 may store map information, for example. The map information is, for example, a numerical map created by the Geospatial Information Authority of Japan. In a numerical map, for example, a road network is represented using nodes and links. Nodes are, for example, points that are placed at road curves, intersections, and other nodes on the road network representation. A link is, for example, a line segment representing a road connecting nodes.

The storage device 64 stores, for example, category information. The category information is, for example, information in which a category for classifying posts and a word belonging to the category are associated with each other. The control device 62 can specify the category of the posted information by, for example, discriminating between the word included in the message posted as the posted information and the category associated with the category information.

The storage device 64 stores, for example, the point name information 10A shown in FIG. In the point name information 10A, for example, the point name and the spot position information are registered in association with each other. The point name is, for example, information indicating the name of the spot. The spot position information is, for example, information indicating the position of a point corresponding to the spot. The point name is, for example, an address, a city / ward / town / village name, a store name, a building name, or a facility name. The position information is represented by, for example, latitude and longitude. The point name information 10A may be included in the map information.

The storage device 64 stores, for example, the spot management information 10B shown in FIG. The spot management information 10B stores, for example, the spot information generated by the generation unit 622. The spot information stored in the spot management information 10B may include the analysis information analyzed by the analyzer 621. In FIG. 21, for example, spot name, spot position information, analysis information, category, media information, date and time information, and spot information associated with a score are registered in the spot management information 10B.

The spot name of the spot management information 10B is, for example, the name of a spot corresponding to the posted information posted on the SNS. In other words, the spot name is the name of the spot to be posted.

The media information is, for example, media information included in an SNS post. Media information includes, for example, still image, moving image, and audio information. The date and time information is information indicating the date and time when the posted information was posted on the SNS. When the spot management information 10B includes the date and time information, for example, by storing only the spot information having the date and time information within a predetermined period from the current time in the storage device 64, only the latest information is spot information. Can be provided to the information display device 5. In the example of the spot management information 10B shown in FIG. 21, the spot name of the spot "N ramen" is registered. "N ramen" and "delicious" are registered as analysis information generated by analyzing the posted information of the spot "N ramen".

When a plurality of spot information is stored in the spot management information 10B, the server device 6 prioritizes and presents the plurality of spot information registered in the spot management information 10B to the user based on the score. Can be done.

The spot information registered in the spot management information 10B is not limited to the one including the spot name, the spot position information, the analysis information, the category, the media information, the date and time information, and the score information, and may include other information. .. For example, the spot management information 10B may include information on the name and address corresponding to the spot. The spot management information 10B may include the telephone number of the spot in addition to the name and address corresponding to the spot. The spot management information 10B may include a URL (Uniform Resource Locator) corresponding to the spot. The spot management information 10B may include the same information as the posted information. The analysis information may include, for example, a hashtag attached to a message posted on the SNS. The spot management information 10B may, for example, merge the POI information indicating the POI included in the map information in advance with the generated posting information.

The spot management information 10B may include, for example, information about favorite spots registered in advance by the user or spots that the user has visited in association with the user.

Hereinafter, the spot information generation process generated by the server device 6 will be described with reference to FIG. 22.

For example, when the execution instruction of the spot information generation process is input to the server device 6, the control device 62 starts the operation flow of FIG. 22.

In S701, the control device 62 collects the posted information posted to the SNS from the external server 8 via the communication device 63. The control device 62 may collect all the posted information from the external server 8 or may collect a part of the posted information. Some post information includes, for example, the latest post posted in the most recent predetermined period, or post information regarding the location of the name of the district, town, or village. For example, the control device 62 may acquire a specific point name from the point name information 10A and collect only the posted information about the acquired point name from the external server 8.

In S702, the control device 62 executes preprocessing on the collected posted information. The preprocessing includes, for example, a process of deleting a line break or a URL included in a post. The preprocessing may include, for example, a process of converting full-width alphanumeric characters into half-width characters, a data normalization process, or a cleansing process. Further, the preprocessing may include, for example, a process of performing morphological analysis on a post and dividing it into morphemes.

In S703, the control device 62 executes a process of extracting a feature word and a key phrase from the post. In the process of S703, the control device 62 operates as, for example, an analyzer 621.

In S704, the control device 62 performs a process of removing unnecessary posts. For example, tweets such as "I'm at ~" posted when checking in at a hotel may be removed because they are likely to be of low utility value to others.

In S705, the control device 62 executes a named entity recognition (NER) process. For the named entity extraction process, for example, GiNZA is used. For example, the control device 62 can label the sentence by executing the named entity extraction on the posted information that has been morphologically analyzed. Label types include:

Date: October 17, 2019 Event: 〇〇 Fireworks display Place: 〇〇 prefecture 〇〇 City Amount: 780 yen Number: Approximately 100 people Organization / organization: Tournament executive committee Others: Typhoon No. 19 Person: Person name, etc. Product: Spring vegetable pasta Time: 18: 00-19: 00

The control device 62 can extract, for example, a proper noun indicating a point name appearing in the posted information and date and time information indicating a date and time by extracting the named entity. As shown in FIG. 23, the control device 62 executes labeling such as “organization / organization” and “event” for the terms included in the posted information. In the process of S705, the user may further modify the labeling given by the named entity extraction. In another embodiment, the control device 62 may perform labeling by machine learning. By using the label added to the posted information by named entity recognition, the control device 62 has the meaning of the posted information such as "where the store handles the menu", "product", and "when to start". Based analysis can be performed. For example, the term "Yabai" may be used with different meanings, such as "it was delicious to eat rice" or "a state of being stuck in something". The control device 62 can classify the meaning of the term "Yabai" into the meaning of "delicious" if, for example, the term to which the place label is added in the named entity extraction represents a restaurant. In named entity recognition using machine learning, posted information is divided into appropriate analysis units and then grouped into one or more analysis units that make up the unique expression. It is possible to determine whether it is an expression. In addition, the control device 62 adds meaning by extracting the named entity, and has a meaning such as "a menu handled at some store", "a product", or "when to start". Extraction can be performed. The control device 62 can also perform named entity extraction by associating the posted information of a plurality of SNS information.

In S706, the control device 62 classifies the categories of posted information. The control device 62 refers to the category information stored in the storage device 64, and identifies the category associated with the word included in the posted information. The control device 62 may use machine learning to identify the posting category. The category of posted information may include the same category as the above-mentioned spot category, or may include the following categories.

News Activities Events Cafes / Cafes Shopping Museums Leisure Restaurants Experience Parks / Gardens Zoos / Aquariums Not applicable Izakaya / Bar Landscapes / Famous hot springs / Spas / Esthetics Shrines / Buddhist temples

In S707, the control device 62 specifies the position information indicating the position of the terminal 9 to which the SNS is posted. For example, the control device 62 specifies the spot name and the position information from the posted information. The control device 62 searches for the point name information 10A stored in the storage device 64, for example, using the morpheme obtained as a result of the morphological analysis. When a point name matching the morpheme is found, the control device 62 identifies the found point name as spot position information. Further, the control device 62 specifies, for example, the found point name as a spot name. The control device 62 may specify the spot name based on the content of the posted information, for example. For example, when the posted information is related to an incident or a traffic jam, it may be preferable to use the content of the incident or information indicating the occurrence of a traffic jam as the spot name rather than using the spot name as the spot name. The control device 62 may determine the information to be used as the spot name according to the content of the post such as the category of the post. For example, when the posted information includes a still image or a moving image, the control device 62 may specify the position information indicating the position of the terminal 9 from the shooting position information of the metadata included in the still image or the moving image. good.

The morpheme used for searching the point name information 10A may be one or two or more. The control device 62 extracts co-occurrence words from two or more words, replaces the co-occurrence words with search words having a high degree of similarity to words pre-classified for each spot, and performs a search. May be good. Here, co-occurrence means that a predetermined word included in the posted information appears at the same time as another word in the posted information. A co-occurrence word is another word that appears at the same time as a predetermined word. The control device 62 may specify the spot name and spot position information corresponding to the posting by using machine learning. In another embodiment, the control device 62 may perform a search for the location name information 10A using the term labeled with the location in the named entity extraction as the spot name.

In S708, the control device 62 extracts the hashtag from the post when the post information includes the hashtag. In S709, when the posted information includes media information, the control device 62 extracts the media information from the posted information.

In S710, the control device 62 performs scoring on the posted information. For example, the control device 62 assigns a score to the date and time of posting so that the newer the post, the higher the score. For example, the control device 62 assigns a score higher to a post having a positive content than that of a post having a negative content, regarding the content of the posted information. For example, the control device 62 gives a higher score to the hashtag of the post when the hot word is included than when the hot word is not included. For example, the control device 62 assigns a score to the media information of the post so that the more aesthetically pleasing the post is, the higher the score is. Aesthetics can be evaluated using, for example, resolution. In other words, the control device 62 assigns a score so that the higher the resolution, the higher the score. The control device 62 determines the score for the post by integrating, for example, the date and time of the post, the content of the post information, the hashtag, and the score of the media information. The control device 62 may calculate, for example, a statistical value of an average value, a median value, a mode value, a maximum value, or a minimum value of a plurality of scores, and use the calculated result as a score. It can be said that the score represents, for example, the utility value of the post. The control device 62 uses the processing information obtained in various processes of feature word and key phrase extraction, named entity extraction, categorization, position information identification, hashtag extraction, and scoring to correspond to posts. Generate information.

In S711, the control device 62 registers the generated spot information in the spot management information 10B, and this operation flow ends. The control device 62 registers, for example, spot information including the information of the spot management information 10B illustrated in FIG. 21. When registering the spot information in the spot management information 10B, the control device 62 may rearrange the spot information and register it in the spot management information 10B based on the score determined in S710. The information processing system 20 can efficiently provide the user with spot information having high utility value by rearranging the spot information based on the score. In the process of S711, the control device 62 operates as, for example, a generation unit 622.

The information included in the spot information is not limited to the example shown in FIG. 21, and some information may not be included, and further information may be included separately. For example, the control device 62 may include the date and time of posting of the SNS used for generating the spot information and the hash tag information in the spot management information 10B.

Further, for example, since a plurality of posted information may be posted for one spot, for example, the control device 62 collectively combines the plurality of posted information for the same spot into the spot management information 10B as one spot information. You may register. The control device 62 can determine whether or not the posting information is for the same spot by using, for example, the spot name, the position information, the category, and the date and time information.

According to the operation flow of FIG. 22, when the posted information collected from the external server 8 includes the posted information regarding the spot feature, the server device 6 generates the analysis information including the spot feature. The server device 6 can generate spot information in which the spot position information specified based on the posted information and the generated analysis information are associated with each other and register the spot information in the spot management information 10B.

Posts that are categorized into news, such as posts about traffic jams and posts about incidents, may require immediacy. It may be desirable to provide posts to users as soon as possible. In one embodiment, some processing in FIG. 22 may be omitted in the generation of spot information corresponding to posts categorized in news. In the generation of the spot information corresponding to the post categorized in the news, for example, the process of extracting the named entity of S705 may be omitted.

Subsequently, the provision of the spot information registered in the spot management information 10B will be illustrated. For example, the server device 6 provides analysis information included in the spot information that matches the requested conditions in response to the provision request from the information display device 5. Among the spot information, there is information that requires immediacy, such as traffic jam information and news information about an incident, or information that has a time limit to be presented to a user. For example, if the traffic jam information is provided to the user after the traffic jam has been resolved over time, erroneous information will be provided to the user. Therefore, the control device 62 of the server device 6 responds to the request for providing spot information from the information display device 5, and when providing the analysis information included in the spot information that matches the requested conditions, the type of information. You may set a limit on the period of provision depending on the situation. For example, in the case of traffic jam information, the control device 62 provides the analysis information to the information display device 5 based on the posted information posted on the SNS within a predetermined time from the time when the request for providing the analysis information is received. May be good. The predetermined time may be appropriately set as, for example, 1 hour, 2 hours, or 3 hours.

When the information display device 5 receives the analysis information provided by the server device 6, the information display device 5 displays, for example, an icon of a spot corresponding to the analysis information on the map displayed on the image display device 57.

In the following, FIG. 24 illustrates an operation flow of analysis information providing processing executed by the control device 62 of the server device 6 according to the present embodiment. The control device 62 starts the operation flow of FIG. 24, for example, when the communication device 63 receives a request for providing analysis information from the information display device 5.

In S1101, the control device 62 determines whether or not the received provision request includes route information. If the received provision request includes route information (YES in S1101), the flow proceeds to S1102.

In S1102, the control device 62 acquires analysis information along the route from the current location of the information display device 5 to the destination from the spot management information 10B. The control device 62 acquires, for example, analysis information corresponding to spot information existing at a predetermined distance or less from the route from the current location to the destination of the information display device 5 found by the search from the spot management information 10B. The analysis information of the spot management information 10B may be, for example, vector information vectorized by the analyzer 621 at a predetermined timing in advance.

In S1101, the control device 62 advances the flow to S1103 when the provision request does not include the route information (S1101 is NO).

In S1103, the control device 62 acquires the analysis information included in the spot information around the current location of the information display device 5 from the spot management information 10B. The control device 62 acquires, for example, analysis information included in the spot information satisfying a predetermined condition with respect to the position indicated by the position information of the information display device 5 from the spot management information 10B.

In S1104, the control device 62 provides the acquired analysis information to the information display device 5 via the communication device 63, and this operation flow ends.

As described above in the present embodiment, the information processing system 20 includes, for example, a generation unit 622, a position information acquisition device 55, and a provision unit 623. The generation unit 622 generates spot information. The spot information is associated with analysis information and spot position information. The analysis information indicates the analysis result of the posted information posted on the SNS. The spot position information indicates the position of the spot specified based on the posted information. The position information acquisition device 55 acquires the position information. The position information acquisition device 55 is an example of a position information acquisition unit. When the providing unit 623 receives the request for providing the analysis information, the providing unit 623 provides the analysis information included in the spot information satisfying a predetermined condition for the position indicated by the position information.

Further, the information processing system 20 may further include, for example, an analyzer 621 that analyzes posted information. The analyzer 621 may analyze the posted information and specify the emotion icon corresponding to the analysis information as the analysis information. When the providing unit 623 receives the request for providing the analysis information, the providing unit 623 may provide an emotion icon corresponding to the spot position information satisfying a predetermined condition for the position indicated by the position information.

Further, the information processing system 20 may further include a route searcher 513. The route searcher 513 searches for a route from the current location to the destination. The provision request includes route information indicating the route. When the providing unit 623 receives the request for providing the posted information for the spot information, the providing unit 623 provides the analysis information along the route.

Further, the information processing system 20 may further include a storage device 64 and an image display device 57. The storage device 64 stores map information. The image display device 57 superimposes the analysis information on the map and displays it at the position indicated by the spot position information.

Therefore, according to the present embodiment, when the posted information is posted on the SNS, the posted information of the spot where the post is analyzed can be displayed on the map so that the user can grasp it. This makes it possible to inform the user of information about the content posted by the SNS for the spot.
