As shown in FIG. 1, the system 10 of the embodiment includes a server 1, an information display device 2, an external server 3, and a terminal 4. The server 1, the information display device 2, the external server 3, and the terminal 4 are connected to, for example, the network 7. The network 7 may be, for example, the Internet or a public communication line network. For example, the terminal 4 connects to the network 7 via a radio base station and a relay device. The terminal 4 can communicate with the external server 3 via the network 7. The server 1 can communicate with the information display device 2 and the external server 3 via the network 7, for example.

The external server 3 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 4 is, for example, an information processing terminal used by a user who posts posted information to an SNS. The terminal 4 is, for example, a smartphone, a mobile phone, a tablet terminal, a personal computer, or a mobile computer. For example, the terminal 4 can access the external server 3 and post the posted information to the SNS by the operation of the user. The posted information includes at least the 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 4 may be provided with, 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 4 may include, for example, a positioning sensor for positioning a position. The terminal 4 can add metadata to a still image or a moving image posted to an SNS by using a positioning sensor. Examples of the positioning sensor include a GPS (Global Positioning System) sensor. Further, the terminal 4 may acquire position information indicating the position of the terminal 4 by using the base stations of a plurality of mobile phones. The position information is represented by, for example, latitude and longitude. Metadata is an example of shooting position information. The shooting position information is information indicating the position where a still image or a moving image was 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 4 provides a message or posted information including the message and shooting data to the external server 3 via the network 7.

The information display device 2 includes, for example, a display device 24. The display device 24 is configured to be able to display a map, for example. The information display device 2 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 2 is, for example, a navigation device mounted on a vehicle. Further, the moving body in which the information display device 2 is held may be a person. In other words, the information display device 2 may be an information processing terminal held by a person. The information display device 2 is not limited to the navigation device. The information display device 2 may be, for example, a smartphone, a tablet terminal, and a mobile computer.

The information display device 2 may include, for example, a positioning sensor different from the positioning sensor of the terminal 4. Examples of the positioning sensor of the information display device 2 include a GPS sensor. The terminal 4 uses the positioning sensor of the information display device 2 to acquire the position information of the current location of the information display device 2. The location information is associated with, for example, a predetermined text tag. When the information display device 2 makes a provision request to the server 1, for example, the information display device 2 transmits the position information of the current location.

The server 1 collects the posted information posted to the SNS from the external server 3, for example. The server 1 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 1 specifies 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 1 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 1 can reflect the information on the hotspots that are booming in the world in the spot information in real time.

In other words, the server 1 can dynamically provide the user with fresh spot information according to the region or the time. 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 1 can also manage the dynamic POI for each time by managing the collected post information for each predetermined time zone, for example.

For example, the server 1 provides the analysis information included in the spot information to the information display device 2 in response to the provision request from the information display device 2. For example, the server 1 may search for spot information around the current location of the information display device 2 based on the position information of the current location transmitted from the information display device 2. The server 1 provides the information display device 2 with analysis information included in the spot information around the current location of the information display device 2 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 for the position indicated by the position information of the information display device 2.

Further, the server 1 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 2, for example. For example, the server 1 may provide the information display device 2 with analysis information corresponding to spot information around the route from the current location to the destination of the information display device 2 found by the search. For example, the server 1 may provide the information display device 2 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 2 found by the search. For example, the server 1 may transmit 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 2 found in the route to the information display device 2. 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.

The information display device 2 can display the analysis information included in the spot information provided by the server 1 on the display device 24. For example, the information display device 2 can superimpose and display the analysis information included in the spot information around the current location on the map. Further, the information display device 2 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 2 to the destination on the map.

By the way, a user may operate a terminal 4 to post, for example, a message regarding a spot feature to an SNS provided by an external server 3. 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 1 collects the posted information expressing the emotion from the external server 3, analyzes the collected posted information, and generates the analysis information. The server 1 can generate spot information including analysis information about emotions from the generated analysis information and provide it to the information display device 2.

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 2 may need to search again using, for example, the name of the spot as a keyword.

When the server 1 of the embodiment receives the request for providing analysis information from the information display device 2, for example, the server 1 provides the spot information of the spot near the current location of the information display device 2 to the information display device 2. The information display device 2 superimposes and displays the analysis information included in the spot information provided by the server 1 on the map. The analysis information includes, for example, the feelings of the poster in the spot. Therefore, the information display device 2 can inform other users' feelings toward the spot. For example, when there is other spot information corresponding to the spot, the server 1 extracts the spot information including the shooting information of the still image or the moving image of the matching spot. Then, the server 1 may provide the extracted spot information to the information display device 2.

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

The information processing system 20 includes, for example, a server 1 and an information display device 2 as shown in FIG.

The server 1 includes, for example, a control unit 11, a communication device 12, and a storage device 13.

The control unit 11 controls, for example, the communication device 12. The control unit 11 controls, for example, the communication device 12 and connects to the network 7. The control unit 11 may control the communication device 12 so that data can be transmitted / received to / from the information display device 2 or the external server 3, for example.

The control unit 11 controls the communication device 12 to receive, for example, a spot search request requesting a search for a predetermined spot from the information display device 2. The spot search request includes, for example, information on the current location, the destination, and the route from the current location to the destination of the moving body including the information display device 2. The control unit 11 searches for a spot around the route from the current location to the destination, for example, in response to a spot search request. By controlling the communication device 12, the control unit 11 causes, for example, the information display device 2 to transmit the spot information found by the search.

Further, the control unit 11 includes, for example, an analysis unit 111, a generation unit 112, and a providing unit 113. The analysis unit 111 acquires the posted information posted to the SNS from the external server 3 via, for example, the communication device 12. In SNS, for example, a service for providing posted information is provided via API (Application Programming Interface). The analysis unit 111 can acquire the posted information from the external server 3 by using the API, for example.

The analysis unit 111 collects messages about spots posted on the SNS as posted information. The analysis unit 111 analyzes the posted information and generates the analysis information. The analysis unit 111 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 analysis unit 111 may analyze the posted information posted on the SNS and use the vector information vectorized 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 analysis unit 111 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. For example, the analysis unit 111 analyzes the posted information posted on the SNS for morphological elements and obtains morphemes. The analysis unit 111 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 1 can prioritize a plurality of spot information based on the score of the spot information scored by the analysis unit 111. For morphological analysis, for example, MeCab can be used.

The analysis unit 111 executes, for example, a process of extracting a key phrase from the posted information posted on the SNS. The analysis unit 111 executes, for example, a process of extracting a feature word from the posted information posted on the SNS. The characteristic word is, for example, a term that characterizes the message contained in the 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 posting, 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 Line 43 a traffic jam ...". A key phrase is, for example, a characteristic phrase that well expresses the subject of a post. In the key phrase extraction process, the analysis unit 111 includes not a "word" meaning a word but a plurality of consecutive words and extracts a "phrase" meaning a phrase.

The analysis unit 111 can extract key phrases by using, for example, a dictionary of key phrases created in advance. The analysis unit 111 can also extract key phrases by using machine learning, for example. The analysis unit 111 can also extract key phrases on a statistical basis or a graph basis, for example. The analysis unit 111 can extract feature words using, for example, a dictionary of feature words created in advance. The analysis unit 111 can extract feature words by using, for example, machine learning. The analysis unit 111 can also extract feature words on a statistical basis or a graph basis, for example. The analysis unit 111 may execute a process of extracting a key phrase and a feature word from the posted information posted on the SNS.

For example, the analysis unit 111 may classify the analysis information generated by analyzing the posted information posted on the SNS into a predetermined category. The analysis unit 111 classifies the predetermined categories 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 analysis unit 111 classifies the analysis information into categories according to the type of the 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 analysis unit 111 is configured to be able to collect messages written by the user to the external server 3 from the external server 3. The analysis unit 111 can also be said to be an information acquisition unit that acquires SNS information from the external server 3.

The generation unit 112 generates spot information. The spot information is associated with analysis information and spot position information. The generation unit 112 stores the generated spot information in the storage device 13.

When the providing unit 113 receives the analysis information provision request from the information display device 2, it controls the communication device 12 to provide the information display device 2 with the analysis information included in the spot information. For example, when the providing unit 113 receives the spot information provision request from the information display device 2, the providing unit 113 may control the communication device 12 to provide the information display device 2 with the analysis information included in the spot information. For example, when the providing unit 113 receives a request for providing analysis information of a spot belonging to a predetermined category, the providing unit 113 may provide the analysis information of the spot belonging to the requested predetermined category to the information display device 2. In this case, the analysis information requested to be provided is, for example, posted 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 analysis unit 111 may provide the plurality of analysis information to the information display device 2.

The storage device 13 stores, for example, various information related to the processing of the server 1. The storage device 13 stores, for example, the point name information 40 shown in FIG. 4 and the spot management information 50 shown in FIG. The storage device 13 may store, for example, map information and category information.

Next, the information display device 2 includes a device control unit 21, a position information acquisition device 22, a device communication device 23, a display device 24, a device storage device 25, and a device input device 26. The device control unit 21 controls, for example, the position information acquisition device 22, the device communication device 23, the display device 24, the device storage device 25, and the device input device 26 of the information display device 2. The device control unit 21 includes, for example, an output unit 211, a transmission unit 212, and a route search unit 213. The output unit 211 outputs, for example, the spot information provided by the provision unit 113 of the server 1 to the display device 24. For example, the device control unit 21 controls the device communication device 23 and connects to the network 7. The device control unit 21 controls the device communication device 23 so that data can be transmitted to and received from the server 1, for example. The device control unit 21 may control the device communication device 23 so that data can be transmitted / received to / from the external server 3 or the terminal 4 in addition to the server 1.

The device storage device 25 stores, for example, various information related to the processing of the information display device 2. The device storage device 25 may store map information, for example. The device control unit 21 causes the display device 24 to display, for example, a map indicated by the map information stored in the device storage device 25.

The position information acquisition device 22 acquires position information indicating the position of the information display device 2 by using, for example, a positioning sensor or a base station of a plurality of mobile phones. The position information acquisition device 22 can acquire position information based on, for example, information from a GPS sensor. 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 22 may acquire position information indicating the position of a point other than the information display device 2. The position information acquisition device 22 may acquire position information indicating a position on a map displayed by the display device 24, 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 21 controls, for example, the position information acquisition device 22 to acquire position information indicating the current location of the device control unit 21. The device control unit 21 displays, for example, icon information indicating the current location on the map displayed on the display device 24 based on the position information acquired from the position information acquisition device 22. This embodiment describes an example in which the position information acquisition device 22 acquires the position information indicating the current location of the moving body on which the information display device 2 is mounted. The embodiment is not limited to the example in which the position information of the moving body is acquired by the position information acquisition device 22.

The device input device 26 is, for example, an input key, a button, a keyboard, a pointing device, a microphone, or a touch panel. In the information display device 2, the user inputs an instruction to search for a route to the destination via the device input device 26. In the information display device 2, the route search unit 213 of the device control unit 21 searches for a route from the current location to the destination by using, for example, the Dijkstra method. The device control unit 21 controls the display device 24 so that, for example, the searched route from the current location to the destination is superimposed on the map and displayed. For example, when a route search instruction for designating a waypoint is input in addition to the destination via the device input device 26, the device control unit 21 searches for a route via the waypoint by the route search unit 213. The device control unit 21 may request the server 1 to search for a route from the current location to the destination, and may acquire the route searched from the server 1. When the server 1 acquires a route in response to a request for a route search from the device control unit 21, the server 1 may have the same function as the route search unit 213.

The device communication device 23 may, for example, transmit a spot search request to the server 1. The device communication device 23 may receive spot information indicating spots in the vicinity along the route, which is transmitted from the server 1 in response to the spot search request. The spot search request includes, for example, the current location acquired by the position information acquisition device 22. The spot search request may include, for example, a destination or a route from the current location to the destination in addition to the current location. The device control unit 21 controls the display device 24 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 embodiment, the spot information is generated based on, for example, a message posted on the SNS provided by the external server 3. For example, when the posted information regarding the feature representing the spot is posted on the SNS provided by the external server 3, the server 1 analyzes the posted posted information and specifies the analysis information regarding the feature representing the spot. Then, the server 1 generates spot information based on the analysis information regarding the feature representing the spot. The feature representing the spot is, for example, the impression of the poster.

For example, when the spot information is received from the server 1, the device control unit 21 superimposes the spot information on the map and displays it on the display device 24. For example, when the user selects specific spot information from a plurality of spot information displayed on the display device 24, the device input device 26 accepts the user's selection. The display device 24 can display the analysis information of the spot information selected by the user in the device input device 26. The display device 24 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 display device 24 displays the analysis information included in the spot information provided from the server 1 without accepting the user's selection. You may. The arbitrary number can be set to any number from 1 to 10, for example.

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 2.

In the point name information 40, 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 place name is, for example, an address, a city / ward / town / village name, a store name, a building name, or a facility name. The spot position information is represented by, for example, latitude and longitude. The point name information 40 may be included in the map information.

The storage device 13 stores, for example, the spot management information 50 shown in FIG. The spot management information 50 stores, for example, the spot information generated by the generation unit 112. The spot information stored in the spot management information 50 may include the analysis information analyzed by the analysis unit 111. In FIG. 5, 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 50.

The spot name of the spot management information 50 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 posting target.

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 50 includes 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 13, only the latest information can be spot information. Can be provided to the information display device 2. In the example of the spot management information 50 shown in FIG. 5, 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 50, the server 1 may prioritize and present the plurality of spot information registered in the spot management information 50 to the user based on the score. can.

The spot information registered in the spot management information 50 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 50 may include information on a name or address corresponding to the spot. The spot management information 50 may include a telephone number of the spot in addition to the name and address corresponding to the spot. The spot management information 50 may include a URL (Uniform Resource Locator) corresponding to the spot. The spot management information 50 may include the same information as the posted information. The analysis information may include, for example, a hash tag attached to a message posted on the SNS.

The spot management information 50 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 1 will be described with reference to FIG.

For example, when the execution instruction of the spot information generation process is input to the server 1, the control unit 11 starts the operation flow of FIG.

In S701, the control unit 11 collects the posted information posted to the SNS from the external server 3 via the communication device 12. The control unit 11 may collect all the posted information from the external server 3 or may collect a part of the posted information. Some of the posted information includes, for example, the latest posted posted in the most recent predetermined period, or posted information regarding the location of the name of the district, town, or village. For example, the control unit 11 may acquire a specific point name from the point name information 40 and collect only the posted information about the acquired point name from the external server 3.

In S702, the control unit 11 executes preprocessing on the collected posted information. The preprocessing includes, for example, a process of deleting a line feed or a URL included in a post. The preprocessing may include, for example, a process of converting full-width alphanumerical characters into a half-width character, 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 unit 11 executes a process of extracting feature words and key phrases from posts. In the process of S703, the control unit 11 operates as, for example, the analysis unit 111.

In S704, the control unit 11 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 have low utility value for others.

In S705, the control unit 11 executes a named entity recognition (NER) process. For the named entity extraction process, for example, GiNZA is used. For example, the control unit 11 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 Festival Place: 〇〇 City, 〇〇 Prefecture Amount: 780 yen Number: Approximately 100 people Organization / Group: Tournament Executive Committee Others: Typhoon No. 19 Person: Person name, etc. Product: Spring vegetable pasta Time: 18: 00-19: 00

By extracting the named entity, the control unit 11 can extract, for example, a named noun indicating a point name appearing in the posted information and date and time information indicating a date and time. As shown in FIG. 7, the control unit 11 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 unit 11 may perform labeling by machine learning. By using the label added to the posted information by named entity recognition, the control unit 11 has the meaning of the posted information such as "where the menu is handled", "product", and "when to start". You can perform based analysis. 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". For example, if the term to which the place label is added in the named entity extraction represents a restaurant, the control unit 11 can classify the meaning of the term "Yabai" into the meaning of "delicious". In named entity recognition using machine learning, posted information is divided into appropriate analysis units and then combined into one or more analysis units that make up the unique expression, and at the same time, what kind of unique analysis unit sequence is collected. It is possible to determine whether it is an expression. In addition, the control unit 11 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 unit 11 can also perform named entity extraction by associating the posted information of a plurality of SNS information.

In S706, the control unit 11 classifies the categories of posted information. The control unit 11 refers to the category information stored in the storage device 13 and identifies the category associated with the word included in the posted information. The control unit 11 may specify the posting category by using machine learning. The category of posted information may include the same category as the above-mentioned spot category, or may include the following categories.
News Activity Event Cafe / Cafe Shopping Museum Leisure Restaurant Experience Park / Garden Zoo / Aquarium Not applicable Izakaya / Bar Landscape / Famous hot springs / Spa / Este Shrine / Temple

In S707, the control unit 11 specifies the position information indicating the position of the terminal 4 to which the SNS is posted. For example, the control unit 11 specifies the spot name and the position information from the posted information. The control unit 11 searches for the point name information 40 stored in the storage device 13, for example, using the morpheme obtained as a result of the morphological analysis. When a point name matching the morpheme is found, the control unit 11 specifies the found point name as spot position information. Further, the control unit 11 specifies, for example, the found spot name as a spot name. The control unit 11 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 unit 11 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 unit 11 may specify the position information indicating the position of the terminal 4 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 40 may be one or two or more. The control unit 11 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 previously 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 unit 11 may specify the spot name and the spot position information corresponding to the posting by using machine learning. In another embodiment, the control unit 11 may execute the search for the point name information 40 by using the term to which the place label is added in the named entity extraction as the spot name.

In S708, the control unit 11 extracts the hashtag from the post when the post information includes the hashtag. In S709, when the posted information includes media information, the control unit 11 extracts the media information from the post.

In S710, the control unit 11 performs scoring on the posted information. For example, the control unit 11 assigns a score to the date and time of the posting so that the newer the post, the higher the score. For example, the control unit 11 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 unit 11 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 unit 11 assigns a score to the media information of the post so that the higher the aesthetics of the post, the higher the score. Aesthetics can be evaluated using, for example, resolution. In other words, the control unit 11 assigns a score so that the higher the resolution, the higher the score. For example, the control unit 11 determines the score for the post by integrating the date and time of the post, the content of the post information, the hash tag, and the score of the media information. The control unit 11 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 unit 11 uses the processing information obtained in various processes of feature word and key phrase extraction, named entity extraction, category classification, position information identification, hash tag extraction, and scoring, and spots corresponding to posts. Generate information.

In S711, the control unit 11 registers the generated spot information in the spot management information 50, and this operation flow ends. The control unit 11 registers, for example, spot information including the information of the spot management information 50 illustrated in FIG. When registering the spot information in the spot management information 50, the control unit 11 may rearrange the spot information and register it in the spot management information 50 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 unit 11 operates as, for example, the generation unit 112.

The information included in the spot information is not limited to the example shown in FIG. 5, and may not include some information, or may include further information. For example, the control unit 11 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 50.

Further, for example, since a plurality of posted information may be posted for one spot, for example, the control unit 11 collectively combines the plurality of posted information for the same spot into the spot management information 50 as one spot information. You may register. The control unit 11 can determine, for example, whether or not the information is posted information for the same spot by using the information of the spot name, the position information, the category, and the date and time information.

According to the operation flow of FIG. 6, when the posted information collected from the external server 3 includes the posted information regarding the spot feature, the server 1 generates the analysis information including the spot feature. The server 1 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 50.

Posts that are categorized into news, such as posts about traffic jams and posts about incidents, may require immediacy. Posts may be desirable to serve users as soon as possible. In one embodiment, some processing in FIG. 6 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 information on the spots registered in the spot management information 50 will be illustrated. For example, the server 1 provides analysis information included in the spot information that matches the requested conditions in response to the provision request from the information display device 2. 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, when the control unit 11 of the server 1 responds to the request for providing spot information from the information display device 2 and provides the analysis information included in the spot information that matches the requested conditions, the information type is changed. You may set a limit on the period of provision accordingly. For example, in the case of traffic jam information, the control unit 11 provides the analysis information to the information display device 2 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 2 receives the analysis information provided from the server 1, for example, the information display device 2 displays an icon of a spot corresponding to the analysis information on the map displayed on the display device 24.

The information display device 2 can control and display the timing of displaying the spot information on the display device 24 and the order of displaying the plurality of spot information on the display device 24. The device control unit 21 controls the order in which the spot information is displayed on the display device 24, the timing at which the spot information is displayed on the display device 24, and the timing at which the spot information is erased from the display device 24. The order in which the spot information is displayed on the display device 24 is an order indicating which type of spot information is preferentially displayed on the display device 24.

The information display device 2 can control the timing of displaying the type of each icon including the emotion icon 641, the knowledge icon 642, the camera icon 643, and the video icon 644 to be displayed on the display device 24. As a result, the user can feel a dynamic feeling. Examples of the timing for displaying each icon include the timing when characters are input based on the user's operation on the information display device 2, the timing when a search is performed, the timing when a spot displayed on a map is passed, and the like. ..

The information display device 2 can function as a center navigation system capable of displaying dynamic spot information on the display device 24, for example, by communicating with the communication device 12 of the server 1. For example, when the information display device 2 is performing a route search, the information display device 2 can guide the user from the current location to the destination using the point indicated by the spot information as a waypoint. The information display device 2 converts the time from the current location to the destination via the stopover of the spot information, and displays the spot information in the order of the longest estimated arrival time or the shortest estimated arrival time to reach the destination. The display can be controlled so that it is displayed. The estimated arrival time may include not only the time of passing through the waypoint but also the staying time of the waypoint in the estimated arrival time.

In the following, FIG. 14 illustrates an operation flow of analysis information provision processing executed by the control unit 11 of the server 1 according to the embodiment. The control unit 11 starts the operation flow of FIG. 14, for example, when the communication device 12 receives the request for providing analysis information from the information display device 2.

In S1101, the control unit 11 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 unit 11 acquires analysis information along the route from the current location to the destination of the information display device 2 from the spot management information 50. For example, the control unit 11 acquires 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 2 found by the search from the spot management information 50. The analysis information of the spot management information 50 may be, for example, vector information vectorized in advance by the analysis unit 111 at a predetermined timing.

In S1101, the control unit 11 advances the flow to S1103 when the provision request does not include the route information (S1101 is NO).

In S1103, the control unit 11 acquires the analysis information included in the spot information around the current location of the information display device 2 from the spot management information 50. For example, the control unit 11 acquires 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 2 from the spot management information 50.

In S1104, the control unit 11 provides the acquired analysis information to the information display device 2 via the communication device 12, and this operation flow ends.
