  In such a search system, only a specific facility such as a parking lot can be used, a dedicated sensor for acquiring external information is required, and only items according to the balance based on past history information The priority order of the facility candidates can only correspond to a specific user such as to be changed, and there is a problem that the versatility is poor.

  On the other hand, when searching for facility candidates based on facility information, the priority order of facility candidates is uniquely determined by the type of facility (for example, station or restaurant) or the user's situation (for example, family structure or preference). is not. Therefore, if an optional function is assigned according to the keyword, the priority order can be easily changed according to the optional function, and the convenience of search for the user can be improved.

  In order to solve the above-described problems, the present invention can easily change the priority order of facility candidates according to an optional function, and can improve the convenience for searching for the user. It is an object to provide a search method, a search program, and a storage medium.

  In order to achieve the above object, a search system according to the present invention refers to a storage unit that stores facility information, an input unit that receives input of a keyword for facility search by a user, and facility information stored in the storage unit. While searching for a plurality of facility candidates from the keywords received by the input unit, and prioritizing the searched plurality of facility candidates based on a predetermined condition, the search unit displays the display unit, When a function keyword related to an optional function is given to the keyword received by the input unit, a predetermined condition is changed based on the optional function.

  According to the present invention, when a function keyword related to an optional function is given to the input keyword, the predetermined condition for prioritizing search is changed based on the optional function, so Therefore, the priority order can be easily changed, and convenience for facility search can be improved for the user.

1 is a block diagram of a search system according to an embodiment of the present invention. 1 shows a search system according to an embodiment of the present invention, where (A) is an explanatory diagram of a facility candidate display example when there is a functional keyword, and (B) is an explanatory diagram of a facility candidate display example when there is no functional keyword. is there. It is a flowchart of the search routine by the control part in the search system which concerns on one embodiment of this invention.

  Next, an embodiment according to the present invention will be described with reference to the drawings.

  The search system shown as the present embodiment is a search system that prioritizes facility information stored in a storage unit based on a keyword input by a user and displays a list, and searches based on facility information in a vehicle navigation system It is applied to the system. In the embodiment described below, since the vehicle navigation system itself can use a known technique, illustration and description of other configurations are omitted except for some system configurations.

  As shown in FIG. 1, the search system 1 includes a vehicle main body (see FIG. 1) for acquiring information related to boarding / running in addition to input information from the input unit 2 for inputting keywords including various input operations by a user. Information from the external information acquisition unit 3 such as various sensors mounted on the vehicle (not shown) and the GPS receiving unit 4, the gyro sensor unit 5 and the acceleration sensor unit 6 mounted on the vehicle for the navigation function. Can do. The search system 1 includes a storage unit 7 that stores a program for executing these navigation functions including facility information, and a search function and a reference function while referring to information from the units 3 to 6 based on the program stored in the storage unit 7. CPU8 which performs a navigation function. The search system 1 includes a display unit 9 that displays map information (MAP) or the like corresponding to the current position as one of navigation functions, a speaker 10 as a notification unit that notifies voice guidance as one of navigation functions, Is provided.

  Although not specifically illustrated, the input unit 2 is, for example, a screen input when a touch panel type liquid crystal monitor is used for the display unit 9, a button switch or a joystick switch provided on the vehicle navigation device body, and the like. . Further, the input unit 2 may be a remote control device dedicated to a navigation device in which a character input key or a conversion key is assigned to a numeric keypad, for example. Furthermore, a portable terminal such as a smartphone in which a predetermined application is installed can be used as the remote control device. Therefore, the input unit 2 may be a receiving unit of a remote control device capable of mutual communication using a short-range wireless method, in addition to various switches that directly input keywords.

  The external information acquisition unit 3 includes, for example, a rain sensor (water droplet detection sensor) for driving the wiper, a seat sensor that detects whether an occupant is seated on the seat, a seat belt sensor that detects whether the seat belt is worn, Various sensors that are already installed in the vehicle, such as timekeeping sensors such as time and calendar, can be used, and dedicated sensors are not separately provided.

  As a result, the CPU 8 can also use, for example, the current weather, the number of passengers or the determination of whether the vehicle is a single ride or a family ride from the past history, the current time such as day and night, etc. as priority order change information. . At this time, the CPU 8 changes the priority so that the user can select whether or not to select a facility candidate after operating an optional function according to the genre of facility information to be searched. For example, in the search system 1 in the navigation function on the premise of driving, when the current time is at night or when the vehicle is a single rider, the priority of facility information to restaurants including alcohol is set. Change to lower.

  For example, the CPU 8 analyzes the characters input by the user by operating the input unit 2, and displays the keyword input frame 9b displayed in the pop-up format or the like on the display screen 9a of the display unit 9 as shown in FIG. Display keywords. The CPU 8 searches for facility candidates by referring to the character data related to the facility information stored in the storage unit 7 when a character input of a predetermined number of characters or more is input from the input unit 2, and selects candidate facility names and the like according to predetermined conditions. A list is displayed in the list display frame 9c. Therefore, the CPU 8 also serves as a search unit for claims.

  When the keyword received by the input unit 2 is given a function keyword related to the option function, the CPU 8 prioritizes the option function and then displays the list format in the candidate list display frame 9c of the display unit 9. Display the multiple facility candidates and functional keywords searched in.

  At this time, the application program interface (API) side including the CPU 8 until it is displayed on the display unit 9 searches for the vicinity of the facility candidate with the function keyword “close order” such as “close order to convenience store”. There is an option search that returns in order, but there is no way to inform the user about it. For this reason, it is desirable to use easy-to-recognize vocabulary, etc. as optional functions, such as “in order of convenience store” or “convenience store XX station” at the timing when the user enters the keyword “convenience store”. At this time, in the process in which the user selects a plurality of facility candidates displayed in a list in the candidate list display frame 9c of the display unit 9 in the list box format by the operation of the input unit 2, the selection target (black and white inversion on the drawing) In the case where the function keyword is included, the contents of the function can be notified from the speaker 10 to the user.

  When the keyword received by the input unit 2 is a general-purpose facility name (for example, “restaurant” or “restaurant”), the CPU 8 selects based on the search history for past optional functions (for example, “children” or “wheelchair”). The candidate list display frame 9c of the display unit 9 displays a plurality of facility candidates and function keywords searched in a list format with priority ranking including

  The CPU 8 is close to the specific facility when the keyword received at the input unit 2 is the specific facility name (for example, “XX station”) and the function keyword is the general-purpose facility name (for example, “convenience store”). It is also possible to determine the priority order to search for general-purpose facilities in order.

  When the restriction information is included in the function keyword (for example, “Izakaya” or “alcohol providing store” or “regular holiday”), the CPU 8 displays the restriction content corresponding to the restriction information on the speaker 10 (or display unit). It is also possible to notify from 9). A specific control function of the CPU 8 as a search system will be described later.

  Note that if the CPU 8 does not include the function keyword, for example, as shown in FIG. 2B, for example, as a normal predetermined condition, for example, in order of increasing proximity to the vehicle position, in descending order of popularity. , Etc. are displayed in a list format in the candidate list display frame 9c of the display unit 9 with the priority order. At this time, as shown in FIG. 2B, the facility candidate is not a function keyword, but a mere store type, a store name, and the like are displayed.

  In the following description, the search in the navigation function is a priority order based on a predetermined condition using a search engine for necessary items from data related to facility information such as addresses, telephone numbers, and names stored in the storage unit 7. Based on the above, it means the destination search that lists facility candidates. The search in the navigation function refers to how to follow a huge number of routes related to the road information stored in the storage unit 7 from the departure place to the determined destination using nodes and links. In this case, it means a route search for finding out whether the destination can be reached efficiently. Then, the CPU 8 has a suggestion function that uses a search engine of the programs stored in the storage unit 7 and sequentially predicts words and phrases closely related to the searched character string and displays them in a list on the display unit 9.

  The display unit 9 is, for example, a touch panel type color liquid crystal screen, and display is controlled via the CPU 8 by a display control driver (not shown) or the like. The display unit 9 specifies the current position based on information acquired by the CPU 8 from the GPS receiving unit 4, the gyro sensor unit 5, and the acceleration sensor unit 6 at normal times, and acquires MAP information around the current position from the storage unit 7. The vehicle's own vehicle mark M and the MAP information are superimposed and displayed. The display unit 9 further superimposes and displays a guideline (not shown) for recognizing the searched route during route guidance. At this time, for example, audio information is output from the speaker 10 at a predetermined distance before turning right or left.

  In such a basic configuration, the search system 1 according to the present embodiment stores the storage unit 7 that stores facility information, the input unit 2 that receives input of keywords for facility search by the user, and the storage unit 7. As a search unit for searching for a plurality of facility candidates from the keywords received by the input unit 2 while referring to the facility information, and displaying the display on the display unit 9 after prioritizing the searched plurality of facility candidates based on a predetermined condition. When the function keyword related to the optional function is assigned to the keyword received by the input unit 2, the CPU 8 changes the predetermined condition based on the optional function to change the optional function to the optional function. The priority order of facility candidates can be easily changed accordingly, and the convenience for searching is improved for the user. A.

  Specifically, a search keyword and a function keyword for operating an optional function are used, and when there is a function keyword effective for the search keyword, the suggest function is validated.

  For example, when the keyword inputted by the user is “XX station convenience store”, the CPU 8 searches for a keyword for a specific facility name, “convenience store” for a keyword for a general facility name, and “station”. Is considered as a function keyword, and an option search suggestion for searching for convenience stores around the station is performed in the closest order. At this time, the method of notifying the user of the suggestion function may be displayed as one item of the area for displaying the candidate list and displaying the effect of the option in the search result together with the candidate list. If there are a plurality of candidate option functions, each is displayed in a list in the candidate list display frame 9c of the display unit 9.

  Conversely, when the user inputs only “XX station”, the CPU 8 determines that “XX station” is a search keyword, and as shown in FIG. The facility candidates including related facilities and the like are searched as the first and displayed in a list in the candidate list display frame 9c of the display unit 9.

  Similarly, when the user inputs “XX station” + “specific store name”, the CPU 8 determines that both are search keywords and uses the store in front of the station as the first priority, related facilities, etc. Are retrieved and displayed in a list in the candidate list display frame 9c of the display unit 9.

  When the user inputs “XX station” + “general-purpose facility name (for example,“ convenience store ”)”, “station” is determined as an optional function keyword, and “convenience store around XX station” is determined. Suggest suggestions that are listed in order of proximity.

  The function keyword does not need to correspond one-to-one with the facility candidate, and can be used as an independent keyword. Therefore, the user can directly input a function keyword for operating an optional function from the input unit 2 in addition to a search keyword indicating a facility name in searching for a facility candidate using a keyword. Conversely, combinations of search keywords and function keywords can be set. Specifically, function options that are often combined with a specific search keyword are extracted by analysis of browsing records for a Web site or log analysis of facility selection results based on past search results. Alternatively, the facility information is analyzed, and a matching option is determined from the data characteristics.

  Specifically, when “restaurant”, which is an abstract store type, is input as a keyword, options such as “restaurant children allowed” “restaurant wheelchair parking” “restaurant smoking allowed” are extracted. Similarly, when the keyword “bearing noodle”, which is a specific product type, is input as a keyword, the user friendly option such as “bearing noodle OR Chinese food” is extracted. Here, the main focus is on suggesting the option search itself, but there is also a suggestion method of proceeding to the point where the result of the option search is shown.

  Next, a control routine executed by the CPU 8 for prioritizing the search system 1 according to the present embodiment will be described based on the flowchart of FIG.

(Step S1)
In step S1, the CPU 8 acquires the current position information acquired from the GPS receiver 4, the gyro sensor 5, and the acceleration sensor 6, and proceeds to step S2.

(Step S2)
In step S <b> 2, the CPU 8 determines whether or not a predetermined number of characters (for example, two characters) have been input from the input unit 2. If the CPU 8 determines that a predetermined number of characters have been input from the input unit 2 (Yes), the CPU 8 proceeds to step S3. If the CPU 8 does not determine that a predetermined number of characters have been input from the input unit 2 (No), the CPU 8 monitors this routine until a predetermined number of characters have been input.

(Step S3)
In step S3, the CPU 8 performs a keyword search using the search engine from the facility information stored in the storage unit 7, and proceeds to step S4.

(Step S4)
In step S4, the CPU 8 determines the priority order of facility candidates to be displayed in a list in the candidate list display frame 9c of the display unit 9 based on predetermined conditions set in advance, and proceeds to step S5. Note that the routine of step S3 and the routine of step S4 may be reversed.

(Step S5)
In step S5, the CPU 8 displays a list of facility candidates in the candidate list display frame 9c of the display unit 9 according to the determined priority order, and proceeds to step S6.

(Step S6)
In step S6, the CPU 8 determines whether there is a functional keyword corresponding to the keyword input by the user through the input unit 2, or whether the keyword input by the user through the input unit 2 is a functional keyword, Is determined based on whether or not a function keyword is included. If the CPU 8 determines that the function keyword is included in the input character (Yes), the CPU 8 proceeds to step S7. When the CPU 8 does not determine that the function keyword is included in the input character (No), the CPU 8 proceeds to step S8.

(Step S7)
In step S7, the CPU 8 changes the predetermined priority order condition for displaying the facility candidates in the candidate list display frame 9c of the display unit 9 according to the function keyword, and loops to step S5. As a result, the CPU 8 displays a list of facility candidates prioritized under the changed new predetermined condition in the candidate list display frame 9c of the display unit 9 together with the function keywords. Note that when the predetermined condition of the priority order is changed, step S6 is skipped.

(Step S8)
In step S <b> 8, the CPU 8 determines whether or not a new character is input from the input unit 2 by the user. If the CPU 8 determines that a new character input has been made (Yes), the CPU 8 loops to step S3, performs a search routine based on the new number of characters, and thereafter repeats this routine each time a character input is added.

(Step S9)
In step S <b> 9, the CPU 8 determines whether or not a function is selected by an input operation (for example, a list box operation) of the input unit 2 by the user. If the CPU 8 determines that the function has been selected (Yes), the CPU 8 loops to step S3 and performs a keyword search according to the function keyword. If the CPU 8 does not determine that the function has been selected (No), the CPU 8 proceeds to step S10.

  When the CPU 8 loops to step S3, specifically, as shown in FIG. 2 (A), when the user selects the keyword “restaurant” and the function keyword “children”, the child-accommodated (or not allowed) restaurant A list of facility candidates that prioritize (store name, etc.) is displayed in a list in the candidate list display frame 9c of the display unit 9. At this time, for example, when the user selects the keyword “restaurant” and the function keyword “smoking permitted”, the facility information includes a restaurant that is always allowed to smoke and a restaurant having a non-smoking time zone. Compared with the current time (and estimated arrival time) acquired from the time sensor, it is possible to change the priority order depending on whether or not it corresponds to the non-smoking time zone. Similarly, the CPU 8 can change the priority for displaying the function keyword “parking with roof” depending on whether or not the rain sensor for driving the wiper detects rain.

(Step S10)
In step S10, the CPU 8 determines whether or not the restriction information is included in the function keyword. If the CPU 8 determines that the restriction information is included (Yes), the CPU 8 proceeds to step S11. If the CPU 8 does not determine that the restriction information is included (No), the CPU 8 proceeds to step S12.

(Step S11)
In step S11, the CPU 8 notifies the user of the content according to the restriction information using the speaker 10 or the display unit 9 as a notification unit, and proceeds to step S12. Thus, for example, it is possible to take appropriate measures such as notifying that the drinking specialty store is a lower priority, notifying that the route search is not performed, or outputting a message to eradicate drunk driving. . At this time, for example, even in a restaurant that provides alcohol, it is possible to change the priority order when the ride is with a family.

(Step S12)
In step S <b> 12, the CPU 8 determines whether or not the destination has been determined from the facility candidates listed in the candidate list display frame 9 c of the display unit 9 by the input operation of the input unit 2 by the user. If the CPU 8 determines that the destination has been determined (Yes), the CPU 8 proceeds to step S13. If the CPU 8 does not determine that the destination has been determined (No), the CPU 8 loops to step S3. In this loop, step S12 may be continuously monitored until the destination is determined instead of step S3, or for example, the loop may be looped to step S8. That is, until this destination is determined, the additional input in step S8 can be handled in the same way as interrupt processing including cancellation or time-over.

(Step S13)
In step S13, the CPU 8 searches the facility information stored in the storage unit 7 for a route from the current position to the destination facility, starts guidance as a navigation function, and ends this routine.

  By the way, the search system 1 of the present invention is not limited to the above-described embodiment, and various modifications have been made to the technical scope described in the claims within the scope of the invention. Includes form.

  For example, the function keyword is defined by the CPU 8 so that the priority order for displaying a list of facility candidates to be displayed in a list in the candidate list display frame 9c of the display unit 9 is hierarchically changed multiple times. Thus, the hierarchy can be set depending on whether or not the user can easily recognize.

  As described above, the search system, the search method, the search program, and the storage medium according to the present invention can easily change the priority order of the facility candidates according to the option function, which is convenient for the user for the search. This is useful for a search system, a search method, a search program, and a storage medium in general that accept the input of a keyword for facility search by a user.
