Preferred embodiments of the present invention will be described below with reference to the drawings.

[overall structure]
FIG. 1 shows the overall configuration of an information display system 1 according to an embodiment of the invention. The information display system 1 includes a server 10 and terminal devices 20 . The terminal device 20 is, for example, a smartphone 20a, a car navigation device 20b mounted on a vehicle, or the like. The terminal device 20 communicates with the server 10 by wireless communication. The server 10 includes a search unit 11 , a search database (hereinafter “database” will be referred to as “DB”) 12 , a tag recommendation unit 13 and a user attribute DB 14 .

First, an outline of the operation of the information display system 1 will be described. The information display system 1 is characterized in that when a user searches for a facility, additional information (hereinafter referred to as "tag information") regarding the facility is displayed along with the search result. The tag information is basically information related to facilities and the like existing in the facility. Specifically, when the user inputs a search word and instructs a search, the server 10 searches for facilities based on the input search word and acquires one or more search results. Further, the server 10 determines tag information to be recommended to the user regarding the facility obtained as the search result based on the search word, the obtained search result, the context, and the user attribute, and uses the tag information. Present to the user along with the search results. Note that the “context” is information indicating the current state of the user.

As a specific example, in the first example, when the user enters the search word "shopping mall" to perform a search, the server 10 acquires facility information of a plurality of shopping malls as search results. In addition to this, the server 10 determines that the user has a baby based on the context and/or user attributes, and when presenting a list of a plurality of shopping malls obtained as a search result, Tag information indicating the nursing room is added to the shopping mall that has it.

In a second example, when the user enters the search word "convenience store" to perform a search, the server 10 acquires facility information of a plurality of convenience stores as search results. In addition, based on the context, the server 10 determines that the user's vehicle has been continuously driven for two hours or longer, and that a woman is riding in the vehicle. When presenting the list of convenience stores in (1), tag information indicating toilets is added to convenience stores equipped with toilets.

In the third example, when the user searches for the search word "facility with parking lot", the server 10 acquires facility information on facilities with parking lots as search results. In addition, based on the context, the server 10 determines that it is highly likely that it will rain when the destination is reached, and presents a list of facilities with multiple parking lots obtained as a search result. , tag information indicating a covered parking lot is added for facilities with a covered parking lot.

Next, specific processing by the information display system 1 will be described with reference to FIG. When the user inputs a search word into the terminal device 20 and instructs a search, the search word 31 and the context 32 are transmitted from the terminal device 20 to the server 10 .

FIG. 2 shows an example of context 32 . The context 32 is acquired by the terminal device 20 and stored in the terminal device 20 . In the example of FIG. 2, the context 32 includes "continuous driving time", "composition of fellow passengers", "weather at destination at estimated time of arrival", "current time", current location, "whether route guidance is in progress". ” and so on. The "continuous driving time" is obtained from the control unit of the vehicle or the navigation device 20b, and the "composition of fellow passengers" is input by the user or obtained from a sensor, camera, or the like provided in the vehicle. The "weather at the destination at the expected arrival time" is obtained by the terminal device 20 from an external server via the Internet or the like. The “current time” can be obtained from the internal clock of the terminal device 20 , and the “current position” can be obtained from the GPS installed in the terminal device 20 . The information “whether route guidance is in progress” can be obtained from the navigation application operating within the terminal device 20 .

Returning to FIG. 1 , the search unit 11 performs a search by referring to the search DB 12 using the search word 31 obtained from the terminal device 20 , and obtains one or more pieces of facility information as search results 34 . Then, the search unit 11 sends the obtained search result 34 , the search word 31 and the context 32 to the tag recommendation unit 13 . The tag recommendation unit 13 acquires the user attribute 33 from the user attribute DB 14 in addition to the search word 31, the context 32 and the search result 34, and determines the tag information 35 to be recommended to the user accordingly. send to The tag information 35 includes tag content 35x as described later. Based on the search results 34 and the tag information 35 , the search unit 11 then transmits search results 36 including the tag information 35 to the terminal device 20 .

The terminal device 20 receives the search result 36 including the tag information 35 and displays it on the display unit. FIG. 3A shows a display example of search results. Note that FIG. 3A shows a display example in the above second example. A user enters a search word "convenience store" to perform a search, and a search result bar 41 indicating four convenience stores is displayed as a search result. Further, since "toilet" is determined as the tag information to be recommended to the user, a tag icon 42 indicating a toilet is displayed in the search result bar 41 of the convenience store having a toilet among the four convenience stores.

Thus, in this embodiment, the search results are displayed based on the search word entered by the user, and when there is tag information 35 to be recommended to the user in consideration of the context and/or user attributes at that time, , a tag icon 42 indicating the tag information 35 is displayed. Therefore, the basic search results can be displayed first, and tag information can be presented to the user in a natural manner.

Further, in the display example shown in FIG. 3A, when the user touches the tag icon 42, the tag content 35x shown in FIG. 3B is displayed. The tag content 35x is information indicating details of the tag information 35 indicated by the tag icon 42. FIG. In the example of FIG. 3B, an in-store map including the toilet is displayed as the tag content 35x for the tag icon 42 of the toilet. By displaying the tag content 35 x when the user selects the tag information 35 in this way, it is possible to provide more detailed information when the user shows interest in the tag information 35 .

In the above description, the search result 34 is an example of the facility information of the present invention, the context 32 is an example of the current situation of the present invention, the tag information 35 is an example of the additional information of the present invention, and the tab icon 42 is an example of the additional information of the present invention. is an example of the additional image of the present invention.

[Search process]
Next, search processing by the information display system 1 will be described. FIG. 4 is a flowchart of search processing. This processing is executed by the server 10 and the terminal device 20 .

First, the terminal device 20 determines whether or not the user has input the search word 31 (step S10). When the search word 31 is input (step S10: Yes), the terminal device 20 transmits the search word 31 and the context 32 at that time to the server 10 (step S11).

The server 10 receives the search word 31 and the context 32, and searches for facilities based on the search word 31 (step S12). If there is a search result (step S13: Yes), the server 10 determines tag information 35 to be recommended based on the search word 31, the search result 34, the context 32 and/or the user attribute 33 (step S14). On the other hand, when there is no search result (step S13: No), the server 10 does not determine the tag information 35. FIG. The server 10 then transmits the search result 36 to the terminal device 20 (step S15). At this time, if the tag information 35 has been determined in step S14, the tag information 35 is included in the search result 36 and transmitted to the terminal device 20. FIG. Further, if there is no search result in step S13, a message or the like to the effect that there is no search result is transmitted to the terminal device 20. FIG.

Upon receiving the search result 36, the terminal device 20 displays a search result bar 41 and a tag icon 42 corresponding to the tag information 35 as illustrated in FIG. 3A (step S16). Next, the terminal device 20 determines whether or not the tag icon 42 has been touched by the user (step S17). If the tag icon 42 is not touched (step S17: No), the process ends. On the other hand, when the tag icon 42 is touched (step S17: Yes), the terminal device 20 displays the tag content 35x corresponding to the tag icon 42 as illustrated in FIG. 3B (step S18). . Then the process ends.

[Tag recommendation section]
Next, the tag recommendation section 13 of the server 10 will be described in detail. As described above, the tag recommendation unit 13 determines the tag information 35 based on the search word 31, the context 32, the user attribute 33, and the search result . FIG. 5 shows a configuration example of the tag recommendation unit 13. As shown in FIG. The tag recommendation unit 13 includes a vector conversion unit 13a, a classifier 13b, and a tag DB 13c.

The vector conversion unit 13a generates a vector based on the input search word 31, context 32 and user attribute 33, and supplies it to the classifier 13b. This vector is matrix data representing combinations of search words 31 , contexts 32 and user attributes 33 . The classifier 13b determines a plurality of candidates for the tag information 35 based on the input vector, selects the most appropriate tag information 35 from among those candidates, and sends it to the tag DB 13c. The tag DB 13c stores tag content 35x corresponding to each facility (POI: Point Of Interest). Based on the search result 34 and the tag information 35 determined by the classifier 13b, the tag recommendation part 13 reads the tag content 35x from tag DB13c, and outputs it with the tag information 35. FIG.

For example, in the above second example, the vector conversion unit 13a generates a vector based on the search word "convenience store", the context, and the user attribute, and inputs the vector to the classifier 13b. The classifier 13b determines the tag information "toilet" that best matches the vector, and inputs it to the tag DB 13c. Also, POIs indicating a plurality of convenience stores are input as search results 34 to the tag DB 13c. The tag DB 13c outputs the contents of the tag (the store map in the above example) together with the tag information for one or more convenience stores having the tag information "toilet".

Next, learning processing of the classifier 13b of the tag recommendation unit 13 will be described. The classifier 13b performs learning according to whether or not the tag information 35 presented to the user was actually selected by the user. That is, as exemplified in FIG. 3A, in a state in which search results that recommend "toilet" as tag information are displayed, search result bars for "A shop" and "C convenience store" having tag information for the user are displayed. When 41 or tag icon 42 is pressed, it is assumed that the user was interested in the tag information "toilet". That is, the tag information "toilet" recommended by the tag recommendation unit 13 is probably what the user was looking for, and the recommendation of the tag information "toilet" is considered to be correct. Therefore, the classifier 13b performs weighting such that the tag information "toilet" is more appropriate in accordance with the combination of the search word, context, and user attribute at that time. As a result, when the same combination is input after that, the probability that "toilet" is determined as tag information increases.

On the other hand, if the user did not press the search result bar 41 or the tag icon 42 of "A shop" and "C convenience store" having tag information, it is presumed that the user was not interested in the tag information "toilet". That is, the recommended tag information "toilet" is probably not what the user was looking for, and the recommendation of the tag information "toilet" is considered to be an incorrect answer. Therefore, the classifier 13b performs weighting such that the tag information "toilet" becomes more inappropriate in accordance with the combination of the search word, context, and user attribute at that time. As a result, when the same combination is input thereafter, the probability that "toilet" will be determined as tag information is reduced. In this way, by learning the classifier 13b based on whether or not the user selects the presented tag information, more appropriate tag information can be presented to the user.

FIG. 6 is a flow chart of the learning process of the classifier 13b. This processing is mainly executed by the tag recommendation section 13 of the server 10 . First, the terminal device 20 transmits to the server 10 the user's selection result for the search results displayed as shown in FIG. The tag recommendation unit 13 determines whether or not the tag icon 42 or the search result bar 41 including the tag icon 42 (hereinafter referred to as "tagged search result bar 41") is selected (step S20).

When the tag icon 42 or the tagged search result bar 41 is selected (step S20: Yes), the tag recommendation unit 13 gives a correct flag to the combination of the search word, context and user attribute at that time (step S21). On the other hand, if the tag icon 42 or the tagged search result bar 41 is not selected (step S20: No), the tag recommendation unit 13 sets an incorrect flag for the combination of the search word, context and user attribute at that time. Give (step S22). Then, the tag recommendation unit 13 performs learning of the classifier 13b based on the result of updating the flag in step S21 or S22 (step S23). Specifically, the weight of the tag information is increased for the combination to which the correct flag is assigned, and the weight of the tag information is decreased to the combination to which the incorrect flag is assigned. Thus, learning of the classifier 13b is performed based on the user's selection of the presented tag information.

[Modification]
Modifications shown below can be applied in combination as appropriate.
(Modification 1)
FIG. 7 shows another display example of search results including tag information. In the example of FIG. 3A, search results are displayed in descending order of distance from the current position regardless of the presence or absence of tag information. On the other hand, in the example of FIG. 7, there is a display mode that prioritizes the distance from the current position (hereinafter referred to as "distance priority mode") and a display mode that prioritizes tag information (hereinafter referred to as "tag priority mode"). called.) can be selected by the user. Specifically, FIG. 7A is an example of the distance priority mode, and each search result is displayed in order of proximity from the current position. Here, when the user presses the switch button 43 labeled "tag priority", the display switches to the tag priority mode shown in FIG. 7B. As shown in FIG. 7B, in the tag priority mode, search results having tag information are preferentially displayed. In FIG. 7(B), when the user presses the switch button 43 labeled "close order", the display switches to the distance priority mode shown in FIG. 7(A). This allows the user to select his/her preferred display mode.

(Modification 2)
In the above embodiment, the determination of the tag information and the provision of the contents of the tag are performed on the server 10 side, but the terminal device 20 side may perform these tasks. Specifically, the search unit 11, the search DB 12, the tag recommendation unit 13, and the user attribute DB 14 provided in the server 10 in the above embodiment are configured in the terminal device 20, and the tag information is determined in the terminal device 20. and present it to the user. In another example, the search unit 11 and the search DB 12 may be provided in the server 10 , and the tag recommendation unit 13 and the user attribute DB 14 may be provided in the terminal device 20 . In this case, the server 10 performs a search based on the search word and transmits the search result to the terminal device 20 . The terminal device 20 may determine the tag information by the tag recommendation unit 13 based on the received search result and present it to the user.

(Modification 3)
In the above embodiment, when the user touches the tag icon 42 in the display example of the search results shown in FIG. 3A, the corresponding tag content is displayed. Instead, when the tag icon 42 is touched, a new search may be performed using the tag content as a search word. For example, when the user touches the tag icon 42 corresponding to "toilet" in the example of FIG. 3A, a new facility search is performed using the search word "toilet". As a result, it is possible to present search results that are mainly based on the tag information "toilet" that the user is interested in.

(Modification 4)
In the above embodiment, the tag information is information on facilities attached to the facility. Alternatively, the tag information may be, for example, information about events or services held at the facility.

(Modification 5)
In the above embodiment, the present invention is applied to searching for facilities in a car navigation system or the like, but instead, the present invention can also be applied to a general Web search or the like. For example, when a user who is watching a drama currently being broadcast (drama name “○○”) searches for “actor”, the details of the search result show that the drama “○○” being watched is If it is included, the search result can be tagged with "XX (actor appearing in drama XX)".
