(Embodiment)
(Functional configuration of point search device)
A functional configuration of the point search apparatus according to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing an example of a functional configuration of the point search apparatus according to the present embodiment.

  In FIG. 1, a point search device 100 includes a table storage unit 101, a keyword input unit 102, a setting unit 103, a start input unit 104, an extraction unit 105, a presentation unit 106, a selection unit 107, and a database 108. And a search unit 109 and an output unit 110.

  The table storage unit 101 stores a table in which attributes for specifying a search technique are associated with keywords. Search methods include name search that searches for the location of the name of the location, Yomi search that searches for the location of the location and the genre search that searches for the genre of the location, the address or area of the location For example, address area search for searching for a location as a target, phone number search for searching for a location for a phone number of a location, and the like.

  The attribute is for specifying a search method. Specifically, a name attribute for specifying name search, a read attribute for specifying read search, a genre attribute for specifying genre search, and an address for specifying address area search. Area attribute, telephone number attribute for specifying telephone number search, and the like.

  Specifically, the keyword is, for example, a word composed of a plurality of characters, and includes a single character kana, alphabets, numbers, and the like. The table storage unit 101 stores an attribute that is likely to be searched when searching for a certain keyword in association with the keyword. As a specific example, the table storage unit 101 stores keywords representing place names such as “Tokyo” and “Saitama” corresponding to the address area attribute. A keyword representing a facility classification such as “hotel” is stored in correspondence with the genre attribute. Further, a keyword indicating a unique name such as “Saitama XX Hotel” is stored as a name attribute in order to represent a specific facility name.

  The keyword input unit 102 receives keyword input from the user. The keyword input unit 102 can accept a plurality of input keywords. Specifically, the keyword input unit 102 receives an input of a keyword using an input button or a touch panel. When inputting a keyword to the keyword input unit 102, it is not necessary to set a search method or an attribute from the user, and an arbitrary keyword can be input.

  The setting unit 103 refers to the table stored in the table storage unit 101 and sets an attribute for the keyword input by the keyword input unit 102 (hereinafter referred to as “input keyword”). Specifically, the setting unit 103 determines which keyword in the table the input keyword matches, and sets an attribute corresponding to the matched keyword to the input keyword.

  For example, when an input keyword “Saitama” is input, an address area attribute is set for the keyword by referring to the table. Further, when an input keyword “Saitama OO Hotel” is input, a name attribute is set for the keyword by referring to the table. In addition, when a plurality of input keywords are input to the keyword input unit 102, the setting unit 103 refers to a table stored in the table storage unit 101 and sets an attribute for each input keyword.

  The database 108 stores information regarding a plurality of points to be searched. Specifically, the information regarding the point includes information such as the facility name, the facility name reading, the genre name, the address name, the latitude / longitude, the telephone number, the area code, and the genre code of the point. The start input unit 104 receives a search start instruction from the user. Specifically, the start input unit 104 includes an input button and a touch panel.

  When the start input unit 104 receives an input and receives an instruction to start a search, the extraction unit 105 extracts a search item including the input keyword in the search method specified by the attribute set in the input keyword. . The search item is an input keyword used for the search or a detail of the input keyword. For example, when a keyword such as “Fujimi” or “Asahi” having a large number of place names is input, such a keyword is selected. It is a specific place name including. That is, search items for keywords such as “Fujimi” and “Asahi” are place names such as “Fujimi City, Saitama Prefecture” and “Fujimi, Tsurugashima City, Saitama Prefecture”.

  When there are a plurality of search items, the presenting unit 106 presents the plurality of search items. As a presentation method, a display screen or sound may be used. On the other hand, the presentation unit 106 does not present a search item when there is a single search item. Specifically, for example, when a single search item is entered, such as when the keyword “Fujimi City, Saitama” is directly input to the keyword input unit 102, the search item is not presented. In addition, when the search item is not extracted by the extraction unit 105, the presentation unit 106 may present that fact and end the search process, or prompt the user to input a keyword again. You may present.

  When a plurality of items are presented by the presentation unit 106, the selection unit 107 receives a selection of one search item from the plurality of search items from the user. Specifically, the selection unit 107 receives a selection from the user using an input button or a touch panel.

  When there are a plurality of search items, the search unit 109 searches the database 108 for a point corresponding to one search item received by the selection unit 107. On the other hand, when the number of search items extracted by the extraction unit 105 is one, a point corresponding to the search item is searched from the database 108. Note that the search method by the search unit 109 is specified by the attribute set in the search item as the input keyword.

  For example, for the search item “Saitama” for which the address area attribute is set, the search unit 109 performs a search using a search method based on an address area search. The output unit 110 displays and outputs the search result by the search unit 109. Specifically, the output unit 110 includes a display, a speaker, and the like.

  In the present embodiment, the keyword input unit 102 may accept input of the first keyword and the second keyword. In this case, the setting unit 103 refers to the table stored in the table storage unit 101, sets the first attribute for the first keyword, and sets the second attribute for the second keyword. Here, for convenience of explanation, the first attribute is an address area attribute, the second attribute is a genre attribute, that is, the first keyword is a word related to a place name, and the second keyword is a word related to a genre.

  In this case, the extraction unit 105 includes the first keyword in the first search method (address area search) specified by the first attribute (address area attribute) when the start input unit 104 receives a search start instruction. The first search item is extracted, and the second search item including the second keyword is extracted in the second search method (genre search) specified by the second attribute (genre attribute).

  The presentation unit 106 presents a plurality of first search items to the user when there are a plurality of first search items and one second search item. That is, the presentation unit 106 presents items related to the address, but does not present items related to the genre. The reason why the word related to the place name is used as the first keyword and the word related to the genre is used as the second keyword is because there are many place names including the same name, such as “Fujimi” described above. This is because such a keyword is assumed to have the highest frequency of input from the user. As for the genre, it is also possible to use the first keyword described above for a word that is used as a relatively large number of trade names such as “Fuji”, “Asahi”, and “Japan” in affiliated stores.

  When the first keyword and the second keyword are received, the selection unit 107 receives the selection of one first search item from the plurality of first search items from the user. The search unit 109 corresponds to one search item received by the selection unit 107 using the first search method (address area attribute), and is set as the second search item using the second search method (genre attribute). Search for the corresponding point.

  In the present embodiment, when the attribute set for the input keyword is a specific attribute, the extraction unit 105 extracts a search item including the input keyword in a search method specified by the specific attribute. To do. The specific attribute is specifically an attribute that specifies a search method using the search list, and typically includes an address area attribute or a genre attribute. The search list is a list including items such as “Fujimi City, Saitama Prefecture” and “Fujimi, Tsurugashima City, Saitama Prefecture” for a predetermined keyword such as “Fujimi”, for example.

  The presentation unit 106 presents a plurality of items as a list. This list is listed in descending order of administrative districts. Specifically, it is listed in the order of prefecture, city, town, village, etc. including “Fujimi”. Further, the list for the genre attribute keywords may be listed in order from the top of the hierarchy, for example. Specifically, for example, the genre of the facility (restaurant, gas station, etc.), the genre of the store (Japanese food, Western food, etc.), the genre of the affiliated store (Fuji Shokudo, Asahi fast food) are listed in order.

  On the other hand, when the search unit 109 receives an input keyword in which an attribute other than a specific attribute is set, and receives an instruction to start a search, the search unit 109 uses the search method specified by the other attribute. Search for a point corresponding to the input keyword. That is, in the case of name search, reading search, and telephone number search other than genre search and address search, a point is searched without receiving search item extraction, search list presentation, or item selection.

(Point search processing procedure of the point search device)
Next, the point search processing procedure of the point search device 100 will be described with reference to FIG. FIG. 2 is a flowchart showing an example of the point search processing procedure of the point search apparatus 100 according to the present embodiment.

  In the flowchart of FIG. 2, the point search device 100 determines whether or not a keyword has been input to the keyword input unit 102 (step S201). It is in a standby state until a keyword is input (step S201: No loop). When a keyword is input (step S201: Yes), the setting unit 103 sets an attribute for the input keyword (step S202). Thereafter, it is determined whether or not an input for starting search has been received from the start input unit 104 (step S203).

  It is in a standby state until an input for search start is received (step S203: No loop). When an input for search start is received (step S203: Yes), the extraction unit 105 extracts search items (step S204). Then, it is determined whether there are a plurality of extracted search items (step S205). When it is determined that there are a plurality of search items (step S205: Yes), the presentation unit 106 presents a plurality of search items (step S206).

  After that, in a state where a plurality of search items are presented, the process waits until a search item selection is received from the user (step S207: No loop). When a search item selection is received (step S207: Yes), the received search is accepted. The search unit 109 searches for a point corresponding to the item (step S208). Then, the search result is output from the output unit 110 (step S209), and the series of processing ends.

  On the other hand, if it is determined in step S205 that the extracted search item is singular (step S205: No), a point corresponding to the extracted search item is searched (step S210), and the search result in step S209 is output. .

  As described above, according to the point search device 100 according to the present embodiment, when there are a plurality of search items, the search is performed by presenting the plurality of search items while the search item is singular. Since the search is performed without presenting the items, in the so-called free keyword search, information necessary for narrowing down can be presented to the user and the user's intention can be accepted, while unnecessary information is presented. You can search without Therefore, it is possible to suppress the setting of the search method from the user and the number of operations at the time of operation, present the search result quickly and accurately, and perform an efficient search.

  In addition, when there are a plurality of first search items and a single second search item for each input keyword having different attributes, the search is performed by presenting the plurality of first search items to the user. In addition to performing the search, it is possible to perform the search without presenting the single second search item to the user.

  As a result, for example, a search is performed using an input keyword of an address area attribute related to a large number of place names such as “Fujimi” that is assumed to have the highest input frequency from a user, and a keyword of a genre attribute such as “Museum”. When “Fujimi” is performed, a search item for specifying which “Fujimi” is present can be presented and narrowed down by the user. Therefore, an accurate search result can be presented. On the other hand, a “museum” whose input keyword itself corresponds to a search item can be searched without presenting the search item. Therefore, without presenting unnecessary information to the user, setting of the search method from the user and the number of operations at the time of operation can be suppressed, and the burden on the user at the time of search can be reduced.

  In addition, when the attribute set to the input keyword is a specific attribute, the search method including the input keyword is extracted in the search method specified by the specific attribute, while other than the specific attribute When an input keyword with an attribute set is accepted, if the point corresponding to the input keyword is searched using the search method specified by another attribute without performing the above extraction, the input keyword The search item can be presented according to the attribute of. Therefore, according to the attribute of the input keyword, unnecessary information can be prevented from being presented to the user, and the user's operation input for accepting the search item can be eliminated, so that the number of operations can be reduced. Can be reduced.

  In addition, if a search item including the input keyword is extracted from search items constituting a search list of a search method specified by a specific attribute, a predetermined attribute and search list can be used. Can be done quickly.

  Further, if the specific attribute is a genre attribute or an address area attribute, it is possible to effectively narrow down a plurality of genre names or address area names including the input keyword with respect to the input keyword. Can be done accurately.

  Further, if the other attributes include at least one of the name attribute, the reading attribute, and the telephone number attribute, the present invention can be applied to the point search device having the multi-search function.

  If a plurality of search items are presented in a list, search items that are easy to see and understand for the user can be presented. Therefore, it is possible to suppress a user's erroneous operation and perform a quick and accurate search.

This Yomi search is to search for a Yomi at a location, and to search for a keyword input in Katakana or Hiragana. Specifically, for the place name “Tokyo”, the “Yomi” attribute is set when “Tokyo” or “Tokyo” is input as an input keyword. For a place name registered as Hiragana in advance, such as “Saitama”, an address area attribute is set for the Hiragana.

  The keyword 402 is a word registered in advance for each attribute 401. The user selection history 403 is history information of changed attributes when an attribute change from a user is accepted. Here, each attribute will be specifically described. In the name attribute, a number of proper nouns such as facility names are recorded, and branch names of affiliated stores are also recorded. That is, all the unique facilities existing on the map are recorded in the name attribute.

  In the address area attribute, a place name is recorded. That is, all place names existing on the map are recorded in the address area attribute. As indicated by reference numeral 410, “name” is recorded in the user selection history 403. This is because “Saitama” 411 is input and the name attribute is received from the user when it is determined as the address area attribute. Indicates that it has been changed. This history may be the latest in the past within a predetermined period, or may be changed frequently. In the genre attribute, the genre of the facility is recorded, and the trade name of the affiliated store is also recorded as the genre.

  In the telephone number attribute, “0 to 9” is shown as the keyword 402. That is, when a number is input, the telephone number attribute is set. In addition to the telephone number attribute, a postal code attribute, a map code attribute, and the like may be recorded. Moreover, you may set the priority at the time of setting an attribute with respect to an input keyword to these number attributes.

(Example of search table recorded on magnetic disk)
Next, an example of a search table recorded on the magnetic disk 305 will be described with reference to FIG. FIG. 5A is an explanatory diagram of an example of a search table recorded on the magnetic disk 305.

  The search table illustrated in FIG. 5A includes a point information table 510, an address table 520, and a genre table 530. The point information table 510 includes a facility name 511, a facility reading 512, a genre code 513, an area code 514, a latitude / longitude 515, and a telephone number 516.

  The facility name 511 is the name of all the facilities existing on the map. Facility Yomi 512 indicates the facility name 511 in katakana. The genre code 513 is a symbol set for each genre when the facilities are classified by genre. The area code 514 is a symbol set for each predetermined area. Latitude / longitude 515 indicates a point where the facility is located. A telephone number 516 indicates the telephone number of the facility.

  The address table 520 includes an address name 521, an area code 514, and a latitude / longitude 515. The address name 521 is all place names existing on the map. This address table 520 records an area code 514 and a latitude / longitude 515 in association with each address name 521.

  The genre table 530 includes a genre name 531 and a genre code 513. The genre name 531 is a name of the classification when the facilities are classified by genre, and includes a trade name of an affiliated store or the like. The genre table 530 records a genre code 513 in association with each genre name 531.

(Example of search item list recorded on magnetic disk)
Next, an example of a list of search items recorded on the magnetic disk 305 will be described with reference to FIG. FIG. 5B is an explanatory diagram of an example of a list of search items recorded on the magnetic disk 305.

  A list 540 illustrated in FIG. 5B includes attributes 541, input keywords 542, and search items 543. The attribute 541 includes an address area attribute and a genre attribute. The input keyword 542 is recorded for each attribute. The search item 543 corresponds to each input keyword 542 and indicates a place name or facility name including the input keyword 542.

  In addition to “Fujimi”, there are many place names recorded nationwide such as “Nakamura” and “Nitta”, and more than one place name registered as address area attribute input keywords 542. A corresponding search item 543 is recorded. As for the genre attribute, in addition to “Asahi”, relatively many affiliated store names such as “Sakura” and “Fuji” are recorded as input keywords 542, and search items 543 corresponding thereto are recorded. Yes.

(An example of attribute setting processing by the navigation device)
First, an example of attribute setting processing by the navigation apparatus 300 will be described with reference to FIGS. 6-1 and 6-2 (hereinafter referred to as FIG. 6). FIG. 6 is a flowchart illustrating an example of attribute setting processing by the navigation device 300. In FIG. 6, it is assumed that an initial screen at the time of point search is displayed in advance by accepting selection of multi-search from the user. This input screen will be described later with reference to FIG.

  In FIG. 6, the CPU 301 of the navigation apparatus 300 determines whether or not a keyword has been input from the user using the input device 310 (step S601). It is in a standby state until a keyword is input (step S601: No loop). When a keyword is input (step S601: Yes), it is determined whether there is a candidate keyword (step S602). The candidate keyword will be described later in detail with reference to FIG. 8, and for example, “Saitama” that is estimated when “sa” is input.

  If it is determined that there is a candidate keyword (step S602: Yes), the candidate keyword is displayed in a recommended conversion candidate box displayed below the input box (step S603). And it is judged whether selection of the keyword by the user was received from the candidate keywords displayed on the recommendation conversion candidate box (step S604). When selection of a candidate keyword is accepted (step S604: Yes), the accepted candidate keyword is displayed in the input box as an input keyword (step S605). Then, using the attribute table 400 shown in FIG. 4, attributes are set for the keywords displayed in the input box (step S606).

  Thereafter, it is determined whether or not there is a keyword input (step S607). When there is a keyword input (step S607: Yes), the process proceeds to step S602. In step S602, when it is determined that there is no candidate keyword (step S602: No), specifically, for example, when a keyword starting with “n” or “tsu” is input, the process proceeds to step S606. Set attributes using keywords as input keywords. The attribute to be set at this time may be determined in advance, for example, as a name attribute.

  If no candidate keyword selection is accepted in step S604 (step S604: No), the process proceeds to step S606, and an attribute is set using the keyword displayed in the input box as the input keyword. If it is determined in step S607 that there is no keyword input (step S607: No), it is determined whether an attribute change has been received from the user (step S608).

  When an attribute change is accepted (step S608: Yes), the attribute is changed to the accepted attribute (step S609). Then, it is determined whether or not the input keyword other than the input keyword for which the attribute is set has been accepted (step S610). Note that the determination in step S610 is specifically a determination of whether or not the “add button” shown in FIG. 7 has been selected. On the other hand, when the attribute change is not accepted in step S608 (step S608: No), the process proceeds to step S610.

  If it is determined that the input of another keyword has been accepted (step S610: Yes), the input keyword with the attribute set is displayed in the input completion box (step S611). The display of the input completion box will be described later with reference to FIG. Thereafter, input of another keyword is accepted (step S612), and the process proceeds to step S602.

  On the other hand, if it is not accepted in step S610 that another keyword is to be input (step S610: No), it is determined whether an input for starting search has been accepted (step S613). It is in a standby state until an input for search start is received (step S613: No loop). When an input for search start is received (step S613: Yes), a search is performed using a table for each attribute (step S614). Details of the search process will be described later with reference to FIGS. Thereafter, the search result is displayed on the display 312 (step S615), and the series of processing ends.

(Example of input screen when searching for points)
Next, an example of the input screen at the time of point search will be described with reference to FIG. FIG. 7 is an explanatory diagram illustrating an example of an input screen at the time of point search. The explanatory diagram shown in FIG. 7 shows a screen displayed as a premise of the flowchart shown in FIG.

  In FIG. 7, the display 312 displays a 50 sound key 701, an input box 702, a guess conversion candidate box 703, an attribute tab 704, an add button 705, and a search start button 706. The 50-sound key 701 lists Japanese hiragana and accepts input from the user by a touch panel. The input box 702 displays the keyword input from the 50 sound key 701.

  The guess conversion candidate box 703 displays candidate keywords based on the characters input from the 50-sound key 701. An attribute tab 704 indicates an attribute to be set as an input keyword. When an attribute is set for a character input from the 50-sound key 701, a tab corresponding to the set attribute is actively displayed. The add button 705 accepts a selection from the user when inputting another keyword having a different attribute. The search start button 706 accepts the start of search for a point corresponding to the input keyword displayed in the input box 702.

(Example of display screen when receiving keyword input from the user)
Next, an example of a display screen when a keyword input is received from the user will be described with reference to FIG. FIG. 8 is an explanatory diagram illustrating an example of a display screen when a keyword input is received from the user. The explanatory diagram shown in FIG. 8 shows the screen displayed in step S603 of the flowchart shown in FIG.

  In FIG. 8, “sa” is displayed in the input box 702 when the user inputs “sa” of the 50-sound key 701. In the candidate conversion candidate box 703, candidate keywords estimated from “sa” are displayed. For example, “Saitama” and “Saga” as place names, and “Circle Store” as a genre of convenience stores are displayed. Is done. This candidate keyword is a keyword extracted based on the latest history when the user inputs “sa”, for example.

  Candidate keywords displayed in the guess conversion candidate box 703 receive selection from the user through the touch panel. On this display screen, for example, if the user selects “Saitama” from the guess conversion candidate box 703, the display screen shown in FIG. 9 is displayed.

(Example of display screen when attributes are set for input keywords)
Next, an example of a display screen when an attribute is set for an input keyword will be described with reference to FIG. FIG. 9 is an explanatory diagram illustrating an example of a display screen when an attribute is set for an input keyword. The explanatory diagram shown in FIG. 9 shows the screen displayed in step S606 of the flowchart shown in FIG.

  In FIG. 9, “Saitama” is displayed in the input box 702. Then, as indicated by reference numeral 900, an attribute tab 704 indicating an address area attribute corresponding to “Saitama” is activated and displayed. Also, in the candidate conversion candidate box 703, candidate keywords whose input is estimated following “Saitama” are displayed. In this display screen, if the user selects “National Art Museum” from the guess conversion candidate box 703, the display screen shown in FIG. 10 is displayed.

(An example of the display screen when the attribute is changed by changing the keyword)
Next, an example of a display screen when an attribute is changed by changing a keyword will be described with reference to FIG. FIG. 10 is an explanatory diagram illustrating an example of a display screen when an attribute is changed due to a keyword being changed. The explanatory diagram shown in FIG. 10 shows the screen displayed in step S606 when there is a continuous input in the flowchart shown in FIG. 6 (step S607: Yes).

  In FIG. 10, “Saitama National Museum” is entered in the input box 702. As indicated by reference numeral 1000, an attribute tab 704 indicating a name attribute corresponding to “Saitama National Art Museum” is activated and displayed. When the search start button 706 is selected by the user on this display screen, a name search for a spot corresponding to “Saitama National Museum of Art” is performed. On the other hand, when the add button 705 is selected on this display screen, the screen shifts to the display screen shown in FIG.

(Example of display screen when attributes are changed by user selection)
Next, an example of a display screen when an attribute is changed by a user's selection will be described with reference to FIG. FIG. 11 is an explanatory diagram illustrating an example of a display screen when an attribute is changed by a user's selection. Note that the explanatory diagram shown in FIG. 11 shows the screen displayed in step S609 when there is continued input in the flowchart shown in FIG. 6 (step S607: Yes).

  In FIG. 11, when the user selects an item indicating the genre attribute from the attribute tab 704 of the touch panel, “Saitama National Museum” is set as the genre attribute, and the genre attribute is indicated as indicated by reference numeral 1100. The attribute tab 704 is activated and displayed. In this display screen, when the user selects the attribute tab 704 indicating the name attribute, the name attribute can be set again. In addition, when an attribute tab 704 indicating an address area attribute, a Yomi (kana) attribute, or a telephone number attribute is selected, the corresponding attribute can be set. For example, even if a genre attribute or a telephone number attribute is set for “Saitama National Museum of Art” and a genre search or a telephone number search is performed, the search result is “not applicable”.

  According to the attribute setting process and the display screen described above, an attribute is set for an input keyword, and a search corresponding to the input keyword is searched using a search method specified by the attribute. In this case, it is possible to perform a search using a so-called free keyword that does not require the user to set a search method. Therefore, the user can reduce the annoyance caused by setting the search method, and can obtain appropriate search results by reducing the misperception of the search method.

  Moreover, since the change of the attribute set to the input keyword is received from the user, when the set attribute is different from that desired by the user, it can be changed to the attribute desired by the user. Therefore, an appropriate search result reflecting the attribute desired by the user can be obtained.

  In addition, since the history information that has received the attribute change is stored and the attribute is set to the input keyword with reference to the table and the history information, the attribute registered in the table in advance for a certain keyword Even if the attribute desired by the user may be different, the user does not need to change the attribute every time, and the attribute desired by the user can be set at the next and subsequent attribute settings.

  In addition, when inputting keywords, candidate keywords are extracted and presented to the user, and candidate keywords accepted from the presented keywords are output as input keywords, so that user keyword input can be supported. The burden of input operation can be reduced.

(Example of search item list display processing performed by the navigation device)
Next, an example of search item list display processing performed by the navigation device 300 will be described with reference to FIGS. FIGS. 12A and 12B are flowcharts illustrating an example of search item list display processing performed by the navigation device 300. In FIGS. 12A and 12B, it is assumed that one or more keywords are input and attributes are already set for the keywords.

  12A, the CPU 301 of the navigation apparatus 300 determines whether an instruction to start a search has been received from the user using the input device 310 (step S1201). It is in a standby state until a search start instruction is received (step S1201: No loop). When a search start instruction is received (step S1201: Yes), an input keyword for which an address area attribute (or genre attribute) is set is displayed. It is determined whether or not there is (step S1202). Note that the case where the genre attribute is set will be described in parentheses in the figure.

  If it is determined that there is an input keyword in which the address area attribute or the genre attribute is set (step S1202: Yes), it is determined whether there is an input keyword in which another attribute is set (step S1203). If it is determined that there is an input keyword with another attribute set (step S1203: Yes), it is determined whether the input keyword with the other attribute set is a genre attribute (step S1204). If it is determined in step S1202 that the genre attribute is set for the input keyword, it is determined in step S1204 whether the attribute is an address area attribute. Hereinafter, the description of the case where the genre attribute is set is only described in parentheses in the figure, and is omitted.

  If it is determined in step S1204 that the input keyword set with another attribute is a genre attribute (step S1204: Yes), each search item of each attribute is extracted (step S1205). Then, it is determined whether or not there are a plurality of search items in the input keyword for which the address area attribute is set (step S1206). If it is determined that there are a plurality of search items in the input keyword set with the address area attribute (step S1206: Yes), it is determined whether there are a plurality of search items in the input keyword set with the genre attribute (step S1206). S1207).

  If it is determined that the input keyword set with the genre attribute does not include a plurality of search items (step S1207: No), the search item for the input keyword of the address area attribute is displayed as a list (step S1208). And it waits until selection of a search item is received (step S1209: No loop), and if selection of a search item is received (step S1209: Yes), a point corresponding to the received search item is searched (step S1210). Then, the search result is displayed (step S1211), and the series of processing ends. Details of the search will be described later with reference to FIGS.

  On the other hand, if it is determined in step S1207 that there are a plurality of search items for the input keyword set with the genre attribute (step S1207: Yes), the search items for the input keyword of the address area attribute and the genre attribute are sequentially displayed in a list. (Step S1212), it is determined whether selection of each search item in Step S1209 has been accepted.

  In step S1206, when it is determined that there are not a plurality of search items in the input keyword for which the address area attribute is set (step S1206: No), that is, when it is determined that there is a single search item, the genre attribute is set. It is determined whether there are a plurality of search items in the input keyword (step S1213). When it is determined that there are a plurality of search items in the input keyword set with the genre attribute (step S1213: Yes), a list of search items for the input keyword with the genre attribute is displayed (step S1214), and the search item in step S1209 is displayed. It is determined whether or not the selection has been accepted.

  In step S1203, when it is determined that there is no input keyword set with other attributes (step S1203: No), that is, when it is determined that there are only input keywords set with an address area attribute or a genre attribute, A search item for the input keyword is extracted (step S1215). If it is determined in step S1204 that the input keyword for which another attribute is set is not a genre attribute (step S1204: No), the process proceeds to step S1215. Thereafter, it is determined whether or not there are a plurality of search items in the input keyword for which the address area attribute is set (step S1216).

  When it is determined that there are a plurality of search items in the input keyword set with the address area attribute (step S1216: Yes), the search items for the input keyword of the address area attribute are displayed in a list (step S1217), and the search item in step S1209 It is determined whether or not the selection is accepted.

  On the other hand, if it is determined in step S1216 that there are no plurality of search items in the input keyword for which the address area attribute is set (step S1216: No), that is, if it is determined that there is a single search item, a list of search items Without displaying or the like, a point corresponding to the input keyword (single search item) is searched (step S1218), and the search result in step S1211 is displayed.

  If it is determined in step S1202 that the address area attribute (or genre attribute) is not set (step S1202: No), that is, if the reading attribute, name attribute, or telephone number attribute is set, search A point corresponding to the input keyword in step S1218 is searched without performing item extraction, list display, or the like. If it is determined in step S1213 that there are no plurality of search items in the input keyword for which the genre attribute is set (step S1213: No), that is, if it is determined that there is a single search item, a list of search items is displayed. For example, a point corresponding to the input keyword (search item) in step S1218 is searched.

(Example of display screen before accepting search start instruction)
Next, an example of a display screen before receiving a search start instruction will be described with reference to FIG. FIG. 12C is an explanatory diagram of an example of a display screen before receiving a search start instruction. The explanatory diagram illustrated in FIG. 12C illustrates the screen displayed in step S1201 of the flowchart illustrated in FIG.

  In FIG. 12C, “Fujimi” is displayed in the input box 702. As indicated by reference numeral 1220, an attribute tab 704 indicating an address area attribute corresponding to “Fujimi” is displayed in an active state. The input completion box 1230 displays that the genre attribute is set for the input keyword “Asahi convenience store”. The notation shown in the input completion box 1230 indicates that the input keyword “Asahi convenience store” has already been input to the input box 702 and the genre attribute has been set for the input keyword. When the user selects the search start button 706 on this display screen, the screen shifts to the screen shown in FIG.

(Example of search item list display after receiving search start instruction)
Next, an example of a list display of search items after receiving a search start instruction will be described with reference to FIG. FIG. 12D is an explanatory diagram of an example of a list display of search items after receiving a search start instruction. The explanatory diagram shown in FIG. 12-4 shows the screen displayed in step S1208 of the flowchart shown in FIG.

  12-4, the display 312 displays a list 1240 of search items for “Fujimi”. When the user selects one from the list, the search item is confirmed and a search is performed.

  In this display screen, the genre attribute “Asahi convenience store” is displayed in the input completion box 1230, but when the genre attribute “Asahi” is displayed in the input completion box 1230, a list 1240 is displayed. After the selection is completed, a list of search items for “Asahi” is displayed. When the user selects one from the list of search items for “Asahi”, the item is confirmed and a search is performed. Note that the list display in this case is the list displayed in step S1212 shown in FIG.

(Another example of the display screen before accepting the search start instruction)
Next, another example of the display screen before accepting a search start instruction will be described with reference to FIG. FIG. 12-5 is an explanatory diagram of another example of the display screen before receiving a search start instruction. The explanatory diagram shown in FIG. 12-5 shows the screen displayed in step S1201 of the flowchart shown in FIG. 12-1.

  In FIG. 12-5, “Asahi convenience store” is displayed in the input box 702. As indicated by reference numeral 1250, an attribute tab 704 indicating a genre attribute corresponding to “Asahi convenience store” is activated and displayed. The input completion box 1230 displays that the address area attribute is set for the input keyword “Fujimi City, Saitama Prefecture”.

  The notation shown in the input completion box 1230 indicates that an input keyword “Fujimi-shi, Saitama” has already been input to the input box 702 and a genre attribute has been set for the input keyword. It should be noted that there is a single search item related to “Asahi convenience store”, that is, there is no genre other than “Asahi convenience store”.

  When the user selects the search start button 706 on this display screen, the search item list is not displayed and the search is started. This indicates a case where the process proceeds from step S1213 to step S1218 in FIGS. 12-1 and 12-2. In other words, when there are multiple search items for each of the input keyword with the genre attribute set and the input keyword with the address area attribute set, the search item list is not displayed and the search is shifted to the search. Yes.

(Example of display screen when attributes are set for multiple input keywords)
Next, an example of a display screen when attributes are set for a plurality of input keywords will be described with reference to FIG. FIG. 13 is an explanatory diagram illustrating an example of a display screen when attributes are set for a plurality of input keywords. Note that the explanatory diagram shown in FIG. 13 shows the screen displayed in step S611 and step S612 in the flowchart shown in FIG. Note that the display screen shown in FIG. 13 is a screen unrelated to the keywords shown in FIGS. 8 to 11, 12-3, 12-4, and 12-5.

  In FIG. 13, input completion boxes 1310 and 1311 are displayed on the display screen. The input completion box 1310 displays that the address area attribute is set for the input keyword “Saitama”. This indicates that the input keyword “Saitama” is input to the input box 702, and an address area attribute is set for the input keyword.

  Furthermore, the input completion box 1311 displays that the genre attribute is set for the input keyword “stadium”. This indicates that, after “Saitama” is input, the user selects the add button 705, and the input keyword “stadium” is input, so that the genre attribute is set for the input keyword. .

  In this display screen, an input keyword “Urawa” is input in the input box 702, and an attribute tab 704 indicating a name attribute is activated and displayed as indicated by reference numeral 1320. Incidentally, the address area attribute is originally set for the keyword “Urawa”, but here the name attribute is set. This is because “Saitama” is already registered as the address area attribute, and is set in advance so as not to accept the input of the address attribute. Note that even if the address area attribute is already registered, it can be set in advance so that the input of the address area attribute can be accepted again.

  When the user selects the search start button 706 on this display screen, an address area search, a genre search, and a name search are performed according to the set attributes for the three input keywords. Details of the search processing will be described below with reference to FIGS. 14-1, 14-2, and 15. FIG.

(Example of details of search processing by navigation device)
Next, an example of details of the search processing by the navigation device will be described with reference to FIGS. 14-1, 14-2, and 15. FIG. FIG. 14A is a flowchart illustrating an example of an area code extraction process in the point search process. The flowchart illustrated in FIG. 14A illustrates processing when an area code is extracted from an input keyword in which an address area attribute is set. 14-1 is based on the display screen shown in FIG. 13, that is, an address area attribute is set for the input keyword “Saitama”, and a genre attribute is set for the input keyword “stadium”. It is assumed that a name attribute is set for the input keyword of “Urawa”.

  14A, the CPU 301 of the navigation device 300 collates the input keyword for the address area (“Saitama”) with the address name in the address table 520 shown in FIG. 5A (step S1401). Then, it is determined whether there is a match as a result of the collation (step S1402). If it is determined that there is a match (step S1402: Yes), the area code “11100” (see reference numeral 514 in FIG. 5A) corresponding to the matched address name is extracted (step S1403).

  Then, the extracted area code “11100” is stored in the buffer 1 (for example, the drive buffer of the magnetic disk drive 304) (step S1404). The number in the buffer is a number determined for convenience for each search result by each attribute. On the other hand, if it is determined in step S1402 that there is no match as a result of the collation (step S1402: No), an invalid value is stored in the buffer 1 (step S1405), and a series of processing ends. The invalid value indicates that there is no point corresponding to the input keyword.

  FIG. 14-2 is a flowchart illustrating an example of a genre code extraction process in the point search process. The flowchart illustrated in FIG. 14B illustrates processing when a genre code is extracted from an input keyword in which a genre attribute is set.

  14B, the CPU 301 of the navigation device 300 collates the input keyword (“stadium”) of the genre name with the genre name in the genre table 530 shown in FIG. 5A (step S1411). Then, it is determined whether there is a match as a result of the collation (step S1412). If it is determined that there is a match (step S1412: Yes), a genre code “1” (see FIG. 5-1, reference numeral 513) corresponding to the matched genre name is extracted (step S1413).

  Then, the extracted genre code “1” is stored in the buffer 2 (step S1414). On the other hand, if it is determined in step S1412 that there is no match as a result of the collation (step S1412: No), an invalid value is stored in the buffer 2 (step S1415), and the series of processing ends.

  FIG. 15 is a flowchart illustrating an example of the name search process in the point search process. The flowchart shown in FIG. 15 is extracted by the input keyword in which the name attribute is set, the area code extracted by the area code extraction process shown in FIG. 14-1, and the genre code extraction process shown in FIG. 14-2. The process at the time of specifying a facility using the made genre code is shown.

  In FIG. 15, the CPU 301 of the navigation device 300 acquires the area code “11100” stored in the buffer 1 (step S1501). Then, the acquired area code “11100” is collated with the area code in the point information table 510 shown in FIG. 5A (step S1502). Then, it is determined whether there is a match as a result of the collation (step S1503). When it is determined that there is a match (step S1503: Yes), the matched spot information is extracted and a search table is created (step S1504). Details of the search table will be described later with reference to FIG.

  Thereafter, the genre code “1” stored in the buffer 2 is acquired (step S1505). Then, the acquired genre code “1” is collated with the genre code in the search table created in step S1504 (step S1506). Then, it is determined whether there is a match as a result of the collation (step S1507). When it is determined that there is a match (step S1507: Yes), the matched spot information is extracted and the search table is recreated (step S1508).

  The facility name input keyword ("Urawa") is collated with the facility name in the search table recreated in step S1508 (step S1509). Then, it is determined whether there is a match as a result of the collation (step S1510). If it is determined that there is a match (step S1510: Yes), the matched point information is extracted and stored in the buffer 3 (step S1511). And the point information preserve | saved at the buffer 3 is output as a search result (step S1512), and a series of processes are complete | finished.

  On the other hand, if it is determined in step S1503 that there is no match as a result of the comparison between the area code and the area code in the point information table 510 (step S1503: No), the fact that there is no corresponding point information is output. (Step S1513), a series of processing ends. If it is determined in step S1507 that there is no match as a result of the comparison between the genre code and the genre code in the search table (step S1507: No), the process proceeds to step S1513. If it is determined in step S1510 that there is no match as a result of collation between the facility name input keyword and the facility name in the re-created search table (step S1510: No), the process proceeds to step S1513. To do.

(Example of search table created in search processing)
Next, an example of a search table created in the search process will be described with reference to FIG. FIG. 16 is an explanatory diagram showing an example of a search table created in the search process.

  In FIG. 16, the first search table 1610 is obtained when there is a match as a result of collation between the acquired area code “11100” and the area code in the spot information table 510 shown in FIG. The table which extracted the point information which corresponded is shown. That is, the first search table 1610 shows the facility information when the area code “11100” (“Saitama”) is extracted from the point information table 510.

  The second search table 1620 extracts matching point information when there is a match as a result of matching between the acquired genre code “1” and the genre code in the first search table 1610. Shows the re-created table. That is, the second search table 1620 indicates the facility name when the genre code “1” (“stadium”) is extracted from the first search table 1610.

  The search result 1630 extracts the matching point information when there is a match as a result of matching between the facility name input keyword (“Urawa”) and the facility name in the second search table 1620. Thus, the output search result is shown. That is, the search result 1630 indicates facility information including the characters “Urawa” from the second search table 1620. That is, “Urawa Stadium” is output as the search result 1630.

  In the above description, the search is performed in the order of area search for creating the first search table 1610, genre search for creating the second search table, and name search for extracting point information from the second search table. However, the order of each search is arbitrary. The display screen when the search result 1630 is output will be described below with reference to FIGS. 17 and 18.

(Example of display screen when search results are output)
Next, an example of a display screen when a search result is output will be described with reference to FIGS. 17 and 18. FIG. 17 is an explanatory diagram illustrating an example of a display screen when one search result is output.

  In FIG. 17, a search result screen 1710 and a map screen 1720 are displayed on the display 312. The search result screen 1710 displays an address of “Urawa Stadium” as a search result. The search result screen 1710 displays a selection button 1711 for receiving an input as to whether or not “Urawa Stadium” is set as the destination. When the user selects “Yes” among the selection buttons 1711, “Urawa Stadium” is set as the destination.

  The map screen 1720 displays a map of the surrounding area centering on “Urawa Stadium”. In this search result screen 1710, only one search result is shown, but when there are a plurality of search results, a plurality of search results may be displayed. A display screen when a plurality of search results are displayed will be described below with reference to FIG.

  FIG. 18 is an explanatory diagram illustrating an example of a display screen when a plurality of search results are output. In FIG. 18, a plurality of search results are listed and displayed on the display 312. In this display screen, for example, when “Urawa Stadium” is selected by the user, the display screen shown in FIG. 17 is displayed. Similarly, when a user selects a point other than “Urawa Stadium”, the display screen is displayed in which each search result screen and map screen are displayed.

  According to the processing and display screen described above, a plurality of keywords (“Saitama”, “stadium”, “Urawa”) are accepted, attributes are set for each input keyword, and a search method specified by each attribute is used. Since a point corresponding to each input keyword is searched, a plurality of input keywords having different attributes can be input on the same screen.

  As described above, according to the navigation device 300 according to the present embodiment, when there are a plurality of search items, a search is performed by presenting the plurality of search items, while when the search item is singular, the search item is displayed. Since the search is performed without presenting, in the so-called free keyword search, information necessary for narrowing down can be presented to the user and the user's intention can be accepted, but unnecessary information is not presented. You can search for Therefore, it is possible to suppress the setting of the search method from the user and the number of operations at the time of operation, present the search result quickly and accurately, and perform an efficient search.

  In addition, when there are a plurality of first search items (address area attribute search items) and one second search item (genre attribute search item) for input keywords set with different attributes, The search is performed by presenting the plurality of first search items to the user, and the search is performed without presenting the single second search item to the user.

  Specifically, as shown in FIG. 12-4, a search is performed using an input keyword of an address area attribute relating to a large number of place names such as “Fujimi” and a keyword of a genre attribute such as “Asahi convenience store”. In the case of performing “Fujimi”, the user can narrow down the search by presenting a search item for specifying “Fujimi”. Therefore, an accurate search result can be presented. On the other hand, for “Asahi convenience store” in which the input keyword itself corresponds to the search item, the search can be performed without presenting the search item. Therefore, without presenting unnecessary information to the user, setting of the search method from the user and the number of operations at the time of operation can be suppressed, and the burden on the user at the time of search can be reduced.

  In addition, when the attribute set to the input keyword is a specific attribute, the search method including the input keyword is extracted in the search method specified by the specific attribute, while other than the specific attribute When an input keyword with an attribute set is accepted, the point corresponding to the input keyword is searched using a search method specified by another attribute without performing the above extraction (FIG. 12). -1 and FIG. 12-2, step S1202: No → see step S1218), the search item can be presented or not presented according to the attribute of the input keyword. Therefore, according to the attribute of the input keyword, unnecessary information can be prevented from being presented to the user, and the user's operation input for accepting the search item can be eliminated, so that the number of operations can be reduced. Can be reduced.

  In addition, since the search item including the input keyword is extracted from the search items constituting the search list of the search method specified by the specific attribute, a predetermined attribute and search list can be used. Can be done quickly.

  In addition, since the specific attribute is a genre attribute or an address area attribute, it is possible to effectively narrow down a plurality of genre names or address area names including the input keyword with respect to the input keyword. Can be done accurately.

  Further, since the other attributes include at least one of a name attribute, a reading attribute, and a telephone number attribute, the present invention can be applied to a point search device having these multi-search functions.

  In addition, since a plurality of search items are presented in a list (see FIG. 12-4), it is possible to present search items that are easy to see and understand for the user. Therefore, it is possible to suppress a user's erroneous operation and perform a quick and accurate search.

  As described above, according to the spot list presentation device, spot list presentation method, spot list presentation program, and recording medium of the present invention, when a search is performed using a plurality of keywords, which keyword is used for which search method. It is not necessary for the user to determine whether it is applicable, and the burden on the user at the time of search can be reduced.

  Note that the point search method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
