Note that the posted text search center 2 that has received the search conditions and vehicle information extracts a posted text that meets the search conditions from the posted text posted on the computer network based on the received search conditions, as will be described later. (S12). Furthermore, based on the received vehicle information, position information related to the posted text is given to the posted text (S13).

  Next, in S <b> 5, the CPU 51 receives information related to the posted text transmitted from the posted text search center 2. The information about the posted message received in S4 is the posted message extracted from the posted message posted on the computer network based on the search condition transmitted in S4, that is, the posted message corresponding to the search condition ( This is information on the corresponding post). Further, the information related to the posted text includes the posted time of the posted text, the posting position, the ID of the poster, and the like, along with the text of the posted text. Further, in S5, the CPU 51 also receives the position information given to the corresponding posted sentence by the position information giving process (S13) described later.

  Thereafter, in S6, the CPU 51 displays on the liquid crystal display 35 information related to the corresponding posted message received in S5 together with the position information given to the corresponding posted message. In addition, the information to be displayed may display all of the text of the posted text, the given location information, the posting time when the posted text was posted, and the ID of the poster. Also good. However, at least the text of the posted text and the position information given to the posted text are displayed.

Here, FIG. 7 is a view showing the posted message guidance screen 71 displayed on the liquid crystal display 35 in S6. As shown in FIG. 7, the posted message guidance screen 71 is composed of two display areas: a left screen 72 that displays a map around the vehicle, and a right screen 73 that displays information related to posted messages.
The left screen 72 displays a map image 74 around the vehicle, a vehicle position mark 75 indicating the current position of the vehicle, and a posting position mark 76 indicating a position specified by the position information given to the displayed posted text. -79.
Further, the right screen 73 is provided with information display spaces 81 to 84 for displaying information related to the posted text. In each information display space 81-84, the ID of the poster who posted the posted text. Display the contents of each post. In addition, as shown in FIG. 8, you may comprise so that the information display spaces 81-84 may be arrange | positioned at the whole screen. In addition, when a predetermined icon displayed on the liquid crystal display 35 is pressed, the information display spaces 81 to 84 may be displayed. Further, when there are a large number of posted sentences, it is desirable that the posted sentences are switched and displayed by a scroll operation. Moreover, when displaying information related to a posted message, a posted message posted at a position close to the vehicle may be displayed with priority. Furthermore, a posted sentence determined to have a high degree of matching with the search condition in the search process (S12) described later may be displayed with priority.
Then, by visually recognizing the posted message guidance screen 71 shown in FIGS. 7 and 8, the user posts the contents related to the information related to the vehicle 5 desired by the user (for example, traffic jam information and traffic stop information). The contents can be browsed, and as a result, information related to the vehicle 5 can be grasped at a faster timing. Further, the position information given to the posted text is information indicating a position that is related to the posted text and that is most likely to reach the vehicle 5 that has requested browsing of the posted text, as will be described later. Therefore, by displaying the position information given to the posted text together with the text of the posted text, it is possible to easily determine whether the posted text is necessary information for the user.

Next, a posted message provision processing program executed in the posted message search center 2 will be described.
First, in S <b> 11, the CPU 21 receives the search condition and vehicle information transmitted from the vehicle 5 that requests to view the posted text.

  Next, in S12, the CPU 21 performs a search process for searching for a posted sentence (corresponding posted sentence) corresponding to the search condition from the posted sentences posted on the computer network using the search condition acquired in S11. Run. Specifically, information on the corresponding posted text is extracted from the posted text information (FIG. 3) stored in the posted text information DB 8 of the posted text information management center 3. As described above, as a search condition, it is possible to set a post time other than the search word and a condition for designating a post position.

  Subsequently, in S13, the CPU 21 executes a position information adding process (FIG. 9) described later. Here, the position information adding process is a process of extracting the position information related to the corresponding posted sentence based on the sentence content of the corresponding posted sentence and giving the extracted position information in association with the corresponding posted sentence.

  Thereafter, in S14, the CPU 21 transmits the information related to the corresponding posted text extracted in S12 to the vehicle 5 that has requested browsing of the posted text together with the position information given in S13. As a result, in the navigation device 6 of the vehicle 5 that has requested browsing of the posted text, information related to the posted text in which the content related to the information related to the vehicle 5 desired by the user (for example, traffic jam information and traffic stop information) is displayed. (S6). In addition, the position information given to the posted text is also displayed.

  Next, the sub-process of the position information adding process executed in S13 will be described with reference to FIG. FIG. 9 is a flowchart of a sub-processing program for position information addition processing.

  The subsequent processes of S21 to S35 are performed for each corresponding posted sentence corresponding to the search condition extracted in S12. Specifically, the processes of S21 to S35 are sequentially executed in order of the posting date for each corresponding posted sentence, and the process proceeds to S14 after the processes of S21 to S35 are performed for all the corresponding posted sentences.

  First, in S <b> 21, the CPU 21 acquires the text content of the corresponding posted text to be processed from the posted text information DB 8 (see FIG. 3) of the posted text information management center 3.

  Next, in S22, the CPU 21 performs morphological analysis on the sentence of the corresponding posted sentence to be processed. Specifically, the sentence of the corresponding posted sentence to be processed is divided into words (morphemes), and each part of speech is determined. Furthermore, regarding words that are identified as nouns, especially whether they correspond to nouns indicating places (Shinagawa, Nagoya, Marunouchi, etc.) or nouns indicating traffic conditions (congestion, lane restrictions, traffic closures, accidents, etc.) Also discriminate.

  Subsequently, in S <b> 23, the CPU 21 determines whether or not “word indicating a place” is included in the sentence of the corresponding posted sentence to be processed. In addition to the name of the administrative division, the word indicating the location also corresponds to a road name, a name of a specific facility such as an interchange or a service area, and the like.

  Then, when it is determined that the “posted word” is included in the sentence of the corresponding posted sentence to be processed (S23: YES), the process proceeds to S24. On the other hand, when it is determined that the “posture word” is not included in the text of the corresponding posted sentence to be processed (S23: NO), the corresponding posted sentence to be processed is changed, and after S21 Run the process again.

  Subsequently, in S <b> 24, the CPU 21 determines whether or not a plurality of “words indicating a place” are included in the sentence of the corresponding posted sentence to be processed.

  Then, when it is determined that a plurality of “words indicating a place” are included in the sentence of the corresponding posted sentence to be processed (S24: YES), the process proceeds to S27. On the other hand, when it is determined that only one “word indicating a place” is included in the sentence of the corresponding posted sentence to be processed (S24: NO), the process proceeds to S25.

  In S <b> 25, the CPU 21 extracts position information related to the corresponding posted text to be processed based on the “word indicating a place” included in the text of the corresponding posted text to be processed. Specifically, the position coordinates of the point specified by the “word indicating a place” are extracted as position information. For example, as shown in FIG. 11, a case where processing is performed for a corresponding posted sentence “A vicinity of XXIC is congested.” Corresponding to “A vicinity of XXIC is congested.” The posted text includes only “XXIC” as a “word indicating a place”. Therefore, the CPU 21 specifies the position coordinates of the point where “XXIC” is located based on the map information stored in the map information DB 12, and uses the position coordinates of the point where “XXIC” is specified as the position information. Will be extracted.

  Next, in S26, the CPU 21 assigns the position information extracted in S25 in association with the corresponding posted text to be processed. The given position information is transmitted to the navigation device 6 together with the corresponding posted text (S14).

On the other hand, in S <b> 27, the CPU 21 determines whether or not each location indicated by a plurality of “words indicating a location” included in the sentence of the corresponding posted sentence to be processed is a location located on the same road. For example, a description will be given of a case where processing is performed for a corresponding posted sentence “From XX IC to XX IC vicinity”. “From XX IC to XX IC is congested.” The corresponding posted sentence includes “XXIC” and “XXIC” as “word indicating the place”. Therefore, the CPU 21 determines whether “XXIC” and “XXIC” are located on the same road.
In S27, the “same road” may be a road having the same road name (for example, Tomei Expressway, National Highway No. XX, Prefectural Road No. XX), or a road having a road-like relationship. However, roads of the same road type may be used.

  On the other hand, in S27, the CPU 21 determines that each location indicated by a plurality of “words indicating a location” included in the text of the corresponding posted sentence to be processed is a location located on the same road ( In S27: YES), the process proceeds to S28. On the other hand, when it is determined that each location indicated by a plurality of “words indicating a location” included in the sentence of the corresponding posted sentence to be processed is not a location located on the same road (S27: NO). To S34.

  In S <b> 28, the CPU 21 specifies a road section included in the corresponding posted sentence based on each location indicated by a plurality of “words indicating a place” included in the sentence of the corresponding posted sentence to be processed. Specifically, the section of the same road between each place indicated by “word indicating a place” is specified. For example, as shown in FIG. 12, in the case where the locations of the points A and B are indicated by two “words indicating the location” included in the sentence of the corresponding post to be processed, the location A and the location B A section 91 of the same road between the two is identified as a road section included in the corresponding posted text.

  Next, in S29, the CPU 21 extracts position information related to the corresponding posted message to be processed based on the road section specified in S28. Specifically, the start point and end point of the road section and the position coordinates of the branch point in the section are extracted as position information. For example, as shown in FIG. 12, when the section 91 of the same road between the points A and B is specified in S28, in addition to the points A and B, the intersection road in the section 91 Crossing point C and point D also correspond. Therefore, the CPU 21 specifies the position coordinates of the points A to D based on the map information stored in the map information DB 12, and extracts the position coordinates of the specified points A to D as position information.

  Subsequently, in S30, the CPU 21 determines whether or not the planned travel route of the vehicle 5 requested to view the posted text has been acquired based on the vehicle information acquired from the vehicle 5 requested to browse the posted text in S11. .

  If it is determined that the planned travel route of the vehicle 5 that has requested to view the posted text has been acquired (S30: YES), the process proceeds to S31. On the other hand, if it is determined that the planned travel route of the vehicle 5 that has requested browsing of the posted text cannot be acquired (S30: NO), the process proceeds to S33.

  In S <b> 31, the CPU 21 sets priorities for the plurality of position information extracted in S <b> 29 based on the planned travel route of the vehicle 5 that has requested browsing of the posted text. Specifically, the priority order is set by giving priority to the position information of the point where the time when the vehicle 5 is predicted to arrive is early. In addition, for the position information of the point where the vehicle 5 is predicted not to reach, priority is given to the position information of the point where the distance from the vehicle 5 when the vehicle 5 is closest to the point is predicted to be short To set the priority.

Hereinafter, the priority setting method in S31 will be described with a specific example. Here, FIG. 13 is a diagram showing a priority setting method for the position information of the points A to D when three different types of planned traveling routes 92 to 94 are acquired.
For example, when the planned travel route 92 is acquired as the planned travel route of the vehicle 5 as shown in (A), among the points A to D, the time at which the vehicle 5 is predicted to arrive is the earliest point C. The highest priority is set for it. For other points A, B, and D where the vehicle 5 is predicted not to reach, priorities are set in the order in which the distance from the vehicle 5 when the vehicle is closest to each point is predicted to be short. To do. As a result, priorities are set in the order of C, D, A, and B.
In addition, as shown in (B), when the planned travel route 93 is acquired as the planned travel route of the vehicle 5, among the points A to D, the time at which the vehicle 5 is predicted to arrive is the earliest point B. On the other hand, the highest priority is set, and the second priority is set for the point D where the vehicle 5 is predicted to arrive next. For other points A and C where the vehicle 5 is predicted not to reach, priorities are set in the order in which the distance between the vehicle 5 and the vehicle 5 when the vehicle is closest to each point is predicted. As a result, priorities are set in the order of B, D, C, and A.
Further, as shown in (C), when the planned travel route 94 is acquired as the planned travel route of the vehicle 5, the point A to D that is predicted to reach the vehicle 5 is the earliest point A. For the point D where the highest priority is set, the second priority is set for the point C where the vehicle 5 is predicted to arrive, and the next point where the vehicle 5 is predicted to be reached The third priority is set, and the fourth priority is set for the point B where the vehicle 5 is predicted to reach last. As a result, priorities are set in the order of A, C, D, and B.

  Thereafter, in S32, the CPU 21 assigns the position information set with the highest priority in S31 in association with the corresponding posted text to be processed. The given position information is transmitted to the navigation device 6 together with the corresponding posted text (S14).

  On the other hand, in S33, the CPU 21 sets priorities for the plurality of pieces of position information extracted in S29 based on the current position and the moving direction of the vehicle 5 that has requested browsing of the posted text. Specifically, the priority order is set by giving priority to the position information of the point where the time when the vehicle 5 is predicted to arrive is early.

The priority order setting method in S33 will be described below with a specific example. Here, FIG. 14 is a diagram illustrating a priority setting method for the position information of the points A to D when the current position and the moving direction of three different types of vehicles 5 are acquired.
For example, as shown in (A), when the current position and the moving direction of the vehicle 5 traveling on the road 95 in the direction of the point C are acquired, the vehicle 5 traveling along the road among the points A to D is obtained. The highest priority is set for the point C having the earliest time predicted to arrive. Further, when the vehicle 5 makes a right or left turn at the point C, the second highest priority is set with respect to the point D where the time when the vehicle 5 is predicted to arrive next to the point C is earlier. Further, when the vehicle 5 makes a right or left turn at the point C, the third highest priority is set for the point A whose time is predicted to arrive after the point D. Furthermore, when the vehicle 5 makes a right or left turn at the point C, the fourth highest priority is set for the point B with the latest time when the vehicle 5 is predicted to arrive. As a result, priorities are set in the order of C, D, A, and B.
Further, as shown in (B), when the current position and the moving direction in which the vehicle 5 travels on the road 96 in the direction of the branch point 97 are acquired, a left turn is made at the branch point 97 among the points A to D. In addition, the highest priority is set for the point B where the time when the vehicle 5 is predicted to arrive is the earliest, and the second priority is set for the point D where the vehicle 5 is predicted to arrive next. Further, the third priority is set for the point C where the vehicle 5 is predicted to arrive next, and the fourth priority is set for the point A where the vehicle 5 is predicted to reach the last. . As a result, priorities are set in the order of B, D, C, and A.
Further, as shown in (C), when the current position and the moving direction of the vehicle 5 traveling on the road A in the direction of the point A are acquired, the vehicle 5 traveling along the road among the points A to D is obtained. The highest priority is set for the point A that is predicted to reach the earliest time, the second priority is set for the point C where the vehicle 5 is predicted to arrive next, and then the vehicle The third priority is set for the point D where 5 is predicted to reach, and the fourth priority is set for the point B where the vehicle 5 is predicted to reach finally. As a result, priorities are set in the order of A, C, D, and B.

  Thereafter, in S32, the CPU 21 assigns the position information set with the highest priority in S33 in association with the corresponding posted text to be processed. The given position information is transmitted to the navigation device 6 together with the corresponding posted text (S14).

  On the other hand, in S <b> 34, the CPU 21 determines whether or not “word indicating traffic condition” is included in the sentence of the corresponding posted sentence to be processed. Note that the traffic status words include traffic jams, lane restrictions, road closures, accidents, and the like.

  Then, when it is determined that “word indicating traffic situation” is included in the sentence of the corresponding posted sentence to be processed (S34: YES), the process proceeds to S35. On the other hand, if it is determined that the sentence of the corresponding posted sentence to be processed does not include “word indicating traffic condition” (S34: NO), the process proceeds to S30. After that, as described above, the priority order is set for each piece of position information specified by a plurality of “words indicating places” based on the planned travel route and the current position of the vehicle 5 (S30 to S33).

  In S35, based on the positional relationship in the sentence between the “word indicating the traffic situation” included in the sentence and the “word indicating the place” from which the position information is extracted, the CPU 21 extracts the plurality of pieces extracted in S29. Priorities are set for position information. Specifically, the modification relation of each word constituting the corresponding posted sentence is specified from the context, and the position information extracted based on the “word indicating the place” modified by the “word indicating the traffic situation” is given priority. Set the priority. For example, as illustrated in FIG. 15, a case where processing is performed on a corresponding post sentence “I am eating home in XX town, but XX IC is congested.” In the corresponding post, “I ’m home after eating rice in XX town, but there ’s a lot of traffic around XX IC.” “XX IC” and “XX town” Is included. In addition, “traffic jam” is included as a “word indicating traffic conditions”. Here, the “word indicating a place” modified by “congestion” from the context is “XXIC”, so the CPU 21 extracts position information (specifically, “XXIC” based on “XXIC”). The highest priority is set to the position coordinates of the point where XXIC is located. Then, the second priority is set for the position information extracted based on “× ○ town” (specifically, the position coordinates of the point where “× ○ town” is located).

  After that, in S32, the CPU 21 assigns the position information set with the highest priority in S35 in association with the corresponding posted text to be processed. The given position information is transmitted to the navigation device 6 together with the corresponding posted text (S14).

As described above in detail, in the posted text providing system 1 according to the present embodiment, the posted text providing method by the posted text providing system 1 and the computer program executed in the posted text providing system 1, a request for browsing the posted text from the vehicle 5. If there is, the search condition and vehicle information are acquired from the vehicle 5 requested to be browsed (S11), and the post sentence corresponding to the acquired search condition is posted from the post sentence posted on the computer network. The corresponding posted sentence is extracted (S12), and based on the content of the corresponding posted sentence and the vehicle information, position information related to the corresponding posted sentence is newly given to the corresponding posted sentence (S13), and the given position information And the corresponding posted text is provided (S14), so when providing the posted text posted on the computer network, the position related to the posted text along with the posted text. By providing information, it is possible to easily determine whether the corresponding posted message is information necessary for the user. In addition, by referring to the position information, it is possible for the user to easily grasp which target related information the posted message has posted information about. In addition, when there are a plurality of pieces of position information extracted from the content of the corresponding posted sentence, the position information to be provided is selected based on the vehicle 5 to be provided with the corresponding posted sentence. Can be provided with position information highly relevant to the vehicle 5, and it is easier to determine whether the corresponding posted sentence is necessary information for the user based on the position information. It becomes possible to make it.
In addition, when there are a plurality of pieces of position information extracted from the content of the corresponding posted sentence, priority is set for each of the plurality of position information based on the vehicle 5 to which the corresponding posted sentence is provided, and the highest priority is set. Since the position information in which the order is set is provided together with the corresponding posted sentence, the position information most relevant to the vehicle 5 can be selected and provided from among the plurality of position information. Therefore, it is possible to make it easier to determine whether or not the corresponding posted sentence is information necessary for the user based on the position information.
In addition, when there are a plurality of pieces of position information extracted from the content of the corresponding posted sentence, when the vehicle 5 arrives based on the planned travel route, the current position, and the moving direction of the vehicle 5 to be provided with the corresponding posted sentence. Since the priority is set with priority given to the position information of the point where the predicted time is early, and the position information with the highest priority set is provided together with the corresponding posted sentence, the vehicle 5 is the first among the plurality of position information It is possible to select the position information of the point that reaches, and give it to the corresponding posted sentence. As a result, it is possible to easily determine whether or not the corresponding posted sentence is information necessary for the user based on the position information.
In addition, when there are multiple pieces of position information extracted from the content of the corresponding posted sentence, the priority order is set for each piece of position information based on the context of the sentence of the corresponding posted sentence, and the highest priority is set. Position information is provided along with the corresponding posted text, so it is possible to select the position information of the point most relevant to the information posted by the posted text from a plurality of location information and assign it to the corresponding posted text. . As a result, it is possible to easily determine whether or not the corresponding posted sentence is information necessary for the user based on the position information.
In addition, when a posted section includes a road section, the location information of the start point, end point, and branch point in the section of the road section is extracted. It is possible to extract it as position information.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the present embodiment, the posted text search center 2 executes the processes of S11 to S14 of the posted text search processing program (FIG. 5), but the posted text information management center 3 and the navigation device 6 are partly or entirely. It is good also as a structure which performs the process of. For example, if the posted text information management center 3 is configured to execute the processes of S11 to S14, the posted text search center 2 becomes unnecessary. Further, instead of the navigation device 6, a communication terminal such as a mobile phone, a PDA, or a smartphone may be used.

  Moreover, in this embodiment, although it is set as the structure which provides position information to the corresponding posted text which is the posted text corresponding to search conditions, it is good also as a structure which provides positional information also to posted text other than the corresponding posted text. For example, it is good also as a structure which provides positional information with respect to each posting text used as search object in the posting text search process of said S12. In that case, based on the given location information (that is, by setting a search condition for designating location information), it is also possible to extract the corresponding posted text from the posted text posted on the computer network. It is.

  Further, in the present embodiment, when a plurality of pieces of position information are extracted from the content of the posted text, the posted text search center 2 sets a priority for each posted text, and the position where the highest priority is set. Although only the information is attached to the corresponding posted sentence and transmitted to the navigation device 6, the extracted plurality of pieces of position information may be transmitted to the navigation device 6 together with the priority order. In that case, the navigation apparatus 6 is configured to select the position information set with the highest priority and display it on the liquid crystal display 35.

  In the present embodiment, when a plurality of pieces of position information are extracted from the content of the posted text, only the position information with the highest priority set is guided by the navigation device 6. It is good also as a structure which guides also about the positional information to which is set.

  In addition, as position information to be added to the posted text, administrative divisions, link numbers, facility IDs, and the like may be associated instead of position coordinates.

  Further, in the present embodiment, the guide route set by the navigation device 6 of the vehicle 5 that has requested posting viewing is transmitted from the navigation device 6 to the posted message search center 2 as the planned travel route of the vehicle 5. However, a configuration may be adopted in which the departure point and the destination set in the navigation device 6 are transmitted instead of the guidance route.

  In the present embodiment, the posted text information management center 3 stores the post text as information about the posted text, the posting time when the posted text was posted, the posting position, the poster ID, and the like. However, it may be configured to store only the text of the posted text.
