Furthermore, the facility evaluation program described above may be stored in a computer-readable storage medium. By doing so, the program can be distributed as a standalone program in addition to being incorporated into a device, and version upgrades can be easily performed.

A facility evaluation device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a schematic configuration diagram of a system having a facility evaluation device according to this embodiment.

The system 100 includes a server device 10, an on-vehicle device 20, and a server device 30. The server device 10 constitutes a facility evaluation device according to this embodiment. The server device 10 is capable of communicating with an on-vehicle device 20 and a server device 30, which will be described later, via a network N such as the Internet.

The server device 10 is a well-known server computer, and includes a CPU (Central Processing Unit), a microprocessor including a memory, a storage device such as a hard disk, a network interface, and the like.

FIG. 2 shows the functional configuration of the server device 10. The server device 10 includes an acquisition section 11, a notification section 12, a determination section 13, and an evaluation section 14.

The acquisition unit 11 acquires evaluation information of a visited facility, which is a facility visited by a user, from a server device 30 described later. The evaluation information in this example includes the evaluation value of the facility. The evaluation value may be a score or a number of stars. Alternatively, it may be one with good, average, or bad reputation. In short, any information indicating the previous reputation of the facility is sufficient. Furthermore, the evaluation information may include comment information by other users regarding the evaluation.

The acquisition unit 11 also acquires comment information regarding the visited facility after the visit to the visited facility from the on-vehicle device 20 . That is, the acquisition unit 11 functions as an evaluation acquisition unit and a comment acquisition unit. The acquisition section 11 mainly functions as a network interface, for example, but a computer program running on a microprocessor also partially functions as the comment acquisition section.

When the acquisition unit 11 acquires comment information, if it includes a predetermined specific keyword, it acquires it as conversation information regarding the visited facility. This predetermined specific keyword is, for example, a word or phrase such as "evaluation," "review," "impression," "word of mouth," or "previous reputation" that indicates that the comment is related to the evaluation of the visited facility. Therefore, the acquisition unit 11 also has functions such as well-known natural language analysis of speech recognition.

The notification unit 12 notifies the user of the evaluation regarding the visited facility based on the evaluation information before visiting the visited facility. This evaluation is based on evaluation information acquired by the acquisition unit 11 from the server device 30. Further, this evaluation is transmitted as voice information or text information to the on-vehicle device 20, and the user is notified from the on-vehicle device 20. Note that the evaluation is not limited to being notified to the user from the in-vehicle device 20, but may be sent to a mobile terminal or the like owned by the user. The notification unit 12 functions as, for example, a network interface.

The determining unit 13 determines the degree of satisfaction with the evaluation information based on the comment information acquired by the acquiring unit 11. Specifically, the determining unit 13 uses sentiment analysis, which is a well-known technique, to determine whether the comment information acquired by the acquiring unit 11 is positive regarding the evaluation information or negative regarding the evaluation information. Classify evaluation information as neither positive nor negative (neutral). If the evaluation information is positive, it is determined that the evaluation has exceeded the evaluation information; if the evaluation information is negative, it is determined that the evaluation has been lower than the evaluation information; and if the evaluation information is neutral, the evaluation It is determined that the information is correct.

The evaluation unit 14 evaluates the visited facility based on the degree of satisfaction determined by the determination unit 13. For example, when the degree of satisfaction exceeds at least the evaluation in the evaluation information, the evaluation unit 14 requests the user to give an evaluation to be reflected in the evaluation information. Specifically, the in-vehicle device 20 outputs a message requesting an evaluation of the facility, and the user inputs the evaluation value and comments by voice. Of course, instead of the in-vehicle device 20, a mobile terminal owned by the user may be used. Here, you may ask for an evaluation of the visited facility even if the satisfaction level is not higher than the evaluation information, but for example, if the user is not satisfied, asking for an evaluation may feel troublesome and the evaluation will not be obtained. Therefore, in this embodiment, the case is assumed to be at least higher than the evaluation in the evaluation information.

Furthermore, if the degree of satisfaction exceeds at least the evaluation in the evaluation information, the evaluation unit 14 may register the facility as a favorite facility. Favorite facilities may be registered in the server device 30 for each user, or if the in-vehicle device 20 is capable of registering favorite facilities, the in-vehicle device 20 may register the favorite facilities. That is, the evaluation section 14 also functions as a registration section.

The determination unit 13 and the evaluation unit 14 function as computer programs that operate on the microprocessor of the server device 10.

The on-vehicle device 20 is a device installed in the vehicle V or a device used within the vehicle V. Specific examples of the on-vehicle device 20 include a car navigation device, a drive recorder, and the like. As shown in FIG. 3, the vehicle-mounted device 20 includes a microphone 21, a camera 22, a control section 23, and a communication section 24. Note that the in-vehicle device 20 is not limited to a device fixed in the vehicle, but may be a portable device brought in by a passenger.

The microphone 21 picks up (acquires) the conversations of users and the like aboard the vehicle V. The microphone 21 converts the acquired conversation into an electrical signal and outputs it to the control unit 23 .

The camera 22 images the inside and outside of the vehicle V. The camera 22 can be used for user authentication, for example, by photographing a user inside the vehicle.

The control unit 23 is composed of a microprocessor having a CPU, memory, and the like. The control unit 23 is in charge of overall control of the vehicle-mounted device 20. In this embodiment, the audio signal acquired by the microphone 21 is transmitted to the server device 10 via the communication unit 24. Further, in the case of a navigation device, the control unit 23 performs a route search from the current location to a set destination and provides guidance along the searched route. In the case of a drive recorder, the video captured by the camera 22 is stored in a storage device (not shown) or transmitted to the server device 10 via the communication unit 24.

The communication unit 24 communicates with the network N wirelessly. The communication unit 24 transmits the above-mentioned conversation audio information and the like to the server device 10.

The server device 30 is a well-known server computer like the server device 10, and includes a microprocessor including a CPU (Central Processing Unit), a memory, etc., a storage device such as a hard disk, a network interface, and the like.

The server device 30 stores facility evaluation information. The evaluation information includes comments from the public regarding the facility evaluation object to be evaluated and evaluation values associated with the comments. Further, the evaluation information accumulated in the server device 30 does not have to be collected only for use in the server device 10. The server device 30 allows an unspecified large number of people to save new comments and evaluation values via the Internet N or the like (this is a service for members, so a specified large number may be used). Furthermore, the evaluation information stored in the server device 30 may be viewable by a third party via the Internet N or the like.

Next, the operation (facility evaluation method) of the server device 10 configured as described above will be explained with reference to the flowchart of FIG. 4. Note that the flowchart in FIG. 4 can be configured as a facility evaluation program by being configured as a program executed by a computer equipped with a CPU or the like.

First, the determination unit 13 identifies a facility to be evaluated (step S11). For example, if the in-vehicle device 20 is a navigation device, it may be specified by acquiring information on a set destination or waypoint. Alternatively, the server device 10 or another server device has POI (Point of Interest) information, and uses the voice recognition function of the acquisition unit 11 to extract facility names included in the POI information around the current location from the acquired comment information. You may identify it by extracting it.

Next, the acquisition unit 11 acquires evaluation information of the facility (visited facility) identified in step S11 from the server device 30 (step S12). Specifically, the evaluation information may be acquired by searching the server device 30 using the specified facility name.

Next, the notification unit 12 outputs the evaluation information acquired in step S12 to, for example, the vehicle-mounted device 20, and causes the vehicle-mounted device 20 to notify the evaluation information as audio from a speaker (not shown) or the like (step S13). Specifically, a notification such as "(facility name)'s evaluation of (service name or site name provided by the server device 30) is x on a possible 0-point scale" is made. In this notification, a relative evaluation with well-known facilities of the same genre may be added. For example, it obtains the evaluation values of facilities of the same genre within a radius of 1 km from the destination, compares them with the average value, and sends a notification such as ``The evaluation of (facility name) is higher than the average of surrounding (genre).'' Good too. Alternatively, the deviation value of the evaluation values of facilities of the same genre may be calculated and the notification may be made in comparison with surrounding facilities. Or, by referring to the history information of the user's visited facilities, such as "The rating is 0 points higher than the (facility name) that I visited last week," it can be compared with the evaluation information of facilities of the same genre that the user has visited in the past. The comparison may be notified as additional information.

Next, the determination unit 13 determines whether the visit has been made after visiting the facility (step S14). The determination after visiting a facility may be performed, for example, by acquiring information from the onboard device 20 indicating that the vehicle has started moving again after arriving at the facility set as a destination or a stopover (evaluation target facility). Alternatively, the movement trajectory of the vehicle V may be periodically acquired from the on-vehicle device 20, and the server device 10 itself may determine whether the vehicle V has arrived at or departed from the evaluation target facility.

If the result of the determination in step S14 is that the facility has not been visited yet (step S14; N), this step is repeated. On the other hand, if it is after visiting the facility (step S14; Y), the acquisition unit 11 acquires comment information about the facility visited by the user (step S15).

Next, the determination unit 13 determines the degree of satisfaction with the evaluation information based on the comment information acquired in step S15 (step S16). Then, the evaluation unit 14 performs evaluation based on the degree of satisfaction determined by the determination unit 13 (step S17).

Note that although the configuration shown in FIG. 2 includes the evaluation section 14, it is not essential. In that case, the degree of satisfaction determined by the determination unit 13 may be notified to the user. Alternatively, the satisfaction level may be output to the server device 30 and reflected in the evaluation value in the server device 30. In other words, the server device 30 or the like may collect the degree of satisfaction with the facility evaluation information.

As is clear from the above description, step S12 functions as an evaluation acquisition process, step S13 functions as a notification process, and step S16 functions as a comment determination process.

Here, a specific example of the operation of the server device 10, which is the facility evaluation device according to this embodiment, will be explained. Assume that a vehicle V equipped with the on-vehicle device 20 has set a restaurant X as a destination. Then, when heading to restaurant X, the server device 10 acquires the evaluation information of restaurant A notification such as "Restaurant X's rating is higher than the average of surrounding restaurants" is provided.

Suppose that on the way back from restaurant X, the user says, "It was better than the word of mouth," as an impression of restaurant X. This statement is acquired by the microphone 21 of the vehicle-mounted device 20 and transmitted from the vehicle-mounted device 20 to the server device 10. Then, the judgment unit 13 classifies the comment as a positive comment through sentiment analysis, and determines the degree of satisfaction as exceeding the evaluation in the evaluation information.

Then, since the degree of satisfaction exceeds the evaluation in the evaluation information, the evaluation unit 14 asks the user for an evaluation, and further registers restaurant X as a favorite facility. Note that a correction operation may be accepted later regarding the user's evaluation.

Furthermore, if the conversation inside the vehicle cannot be confirmed or if there is only one passenger in the vehicle, the vehicle-mounted device 20 may make an utterance that will trigger the conversation. For example, on the way back from Restaurant X, the in-vehicle device 20 makes utterances such as "What kind of restaurant was Restaurant X?" and "Did you enjoy the meal?" The in-vehicle device 20 acquires responses to these utterances and transmits them to the server device 10, and the server device 10 determines and evaluates the degree of satisfaction as described above.

According to this embodiment, the server device 10 uses the acquisition unit 11 to acquire evaluation information of the visited facility, and the notification unit 12 notifies the user of the evaluation regarding the visited facility based on the evaluation information before visiting the visited facility. Then, the acquisition unit 11 acquires comment information regarding the visited facility after the visit, and the determination unit 13 determines the degree of satisfaction with the evaluation information based on the acquired comment information. By doing so, it is possible to evaluate the degree of satisfaction with the evaluation information of the visited facility based on the comment information regarding the visited facility after the visit to the visited facility. In other words, it is possible to obtain satisfaction with the previous reputation. Therefore, it becomes clear what the user is satisfied with or not, and it is possible to appropriately evaluate the level of satisfaction with the facility. In addition, if the server device collects the satisfaction level of evaluation information of a certain facility from a large number of users, it becomes possible to evaluate the appropriateness and validity of the evaluation value (previous reputation) given to the facility. .

Further, the determination unit 13 determines that the degree of satisfaction is either higher than the evaluation in the evaluation information, lower than the evaluation in the evaluation information, or as per the evaluation information. By doing so, it becomes possible to make a relative judgment as to whether the previous reputation was good or bad.

The system also includes an evaluation section 14 that evaluates the visited facility based on the degree of satisfaction determined by the determination section 13. By doing so, it is possible to evaluate the visited facility based on the degree of satisfaction.

Furthermore, when the degree of satisfaction exceeds at least the evaluation in the evaluation information, the evaluation unit 14 may ask the user for an evaluation to be reflected in the evaluation information. By doing so, at least when the user is satisfied, an evaluation including evaluation values, comments, etc. can be obtained.

Furthermore, the evaluation unit 14 can register a favorite facility, and if the degree of satisfaction exceeds at least the evaluation in the evaluation information, the evaluation unit 14 may register the facility as a favorite facility. By doing so, at least if the user is satisfied with the facility, the facility can be registered as a favorite to make it easier to visit the facility in the future.

Further, the determination unit 13 determines the satisfaction level based on whether the content of the comment information is positive about the evaluation information, negative about the evaluation information, or neither positive nor negative about the evaluation information. Judging. By doing so, the satisfaction level can be determined by analyzing the emotions contained in the user's comments using a well-known method such as sentiment analysis.

Further, the acquisition unit 11 acquires conversation information regarding the visited facility when a predetermined specific keyword is included. By doing so, for example, conversations including keywords such as "evaluation" and "review" can be acquired and judged, and heavy processing such as analyzing all comments is not necessary.

Further, the visited facility may be a destination or a waypoint, and the notification unit may notify the user of an evaluation regarding the visited facility along with guidance to the destination or waypoint. By doing so, it is possible to evaluate the visited facility during guidance using a navigation device or the like.

In addition, although in the example mentioned above, the server apparatus 10 was equipped with the acquisition part 11, the notification part 12, the determination part 13, and the evaluation part 14, it is not limited to this form. For example, the in-vehicle device 20 may function as the acquisition unit 11 and the notification unit 12. Furthermore, the on-vehicle device 20 may function as a facility evaluation device.

Further, the present invention is not limited to the above embodiments. That is, those skilled in the art can implement various modifications based on conventionally known knowledge without departing from the gist of the present invention. Of course, such modifications fall within the scope of the present invention as long as the facility evaluation device of the present invention is still provided.
