Embodiment
(Functional configuration of point search device)
The 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, the point search apparatus 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. , A search unit 109, and an output unit 110.

  The table storage unit 101 stores a table in which an attribute for specifying a search method is associated with a keyword. The search method is a name search that searches for points for the names of points, a Yomi search that searches for points for the points of Yomi, a genre search that searches for the genre of points, an address or area of the points An address area search for searching for a point as a target, a telephone number search for searching for a point for a telephone number of a point, and the like can be mentioned.

  The attribute is for specifying a search method, and more specifically, a name attribute for specifying a name search, a yomi attribute for specifying a yomi search, a genre attribute for specifying a genre search, an address for specifying an address area search An area attribute, a telephone number attribute specifying a telephone number search, and the like can be mentioned.

  Specifically, the keyword is, for example, a word composed of a plurality of characters, and also includes one-character pseudonym, an alphabet, 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” in correspondence with the address area attribute. Moreover, the keyword showing the classification of facilities, such as a "hotel", is memorize | stored corresponding to a genre attribute. Furthermore, a keyword indicating a unique name such as "Saitama XX hotel" is stored as a name attribute in order to indicate a specific facility name.

  The keyword input unit 102 receives an input of a keyword 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. Note that when inputting a keyword into 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 in the keyword (hereinafter referred to as “input keyword”) input by the keyword input unit 102. Specifically, the setting unit 103 determines which keyword in the table the input keyword matches, and sets an attribute corresponding to the matched keyword as the input keyword.

  For example, when the input keyword "Saitama" is input, the address area attribute is set to the keyword by referring to the table. In addition, when the input keyword "Saitama XX hotel" is input, the name attribute is set to 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 the table stored in the table storage unit 101 and sets an attribute to each input keyword.

  The database 108 stores information on a plurality of points to be searched. Specifically, the information on the point is information such as the facility name, the facility name, the genre name, the address name, the latitude and longitude, the telephone number, the area code, and the genre code of the point. The start input unit 104 receives an instruction to start a search 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, the extraction unit 105 receives a search start instruction, and 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" in which a large number of place names exist, such a keyword is used. 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 City in Tsurugashima City, Saitama Prefecture".

  The presentation unit 106 presents the plurality of search items when there are a plurality of search items. As a method of presentation, a display screen or sound may be used. On the other hand, when the search item is singular, the presentation unit 106 does not present the search item. Specifically, for example, when the search item is singular, such as when the keyword "Fujimi City, Saitama Prefecture" is directly input to the keyword input unit 102, the search item is not presented. In addition, when a search item is not extracted by the extraction unit 105, the presentation unit 106 may present a message indicating that the search process is to be ended and prompt the user to input a keyword again. You may show the effect.

  When the presentation unit 106 presents a plurality of items, the selection unit 107 receives, from the user, selection of one search item from among the plurality of search items. Specifically, the selection unit 107 receives a selection from the user via 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 accepted 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. 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” in which the address area attribute is set, the search unit 109 performs a search using a search method by 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.

  Further, in the present embodiment, the keyword input unit 102 may receive 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 to set the first attribute in the first keyword and sets the second attribute in 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, when the start input unit 104 receives a search start instruction, the extraction unit 105 includes the first keyword in the first search method (address area search) specified by the first attribute (address area attribute). The first search item is extracted, and the second search item including the second keyword is extracted in a second search method (genre search) specified by the second attribute (genre attribute).

  The presentation unit 106 presents the plurality of first search items to the user when there are a plurality of first search items and one second search item. That is, while the presentation unit 106 presents an item regarding an address, it does not present an item regarding a genre. It should be noted that the reason why the word relating to the place name is used as the first keyword and the word relating 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. With regard to genres, in the affiliated shops and the like, it is also possible to set the first keyword described above, for example, to a word used relatively frequently as a trade name such as “Fuji”, “Asahi”, “Japan”.

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

  Further, in the present embodiment, when the attribute set in the input keyword is a specific attribute, the extraction unit 105 extracts a search item including the input keyword in the search method specified by the specific attribute. Do. The specific attribute is specifically an attribute specifying a search method using a search list, and typically includes an address area attribute or a genre attribute. The search list is, for example, a list including items such as "Fujimi City in Saitama Prefecture" and "Fujimi City in Tsurugashima City in Saitama Prefecture" with respect to predetermined keywords such as "Fujimi".

  The presentation unit 106 lists and presents a plurality of items. This list is listed in descending order of administrative districts. Specifically, "Fujimi" is listed in the order of prefectures, cities, towns, villages, and so on. Also, the list for keywords of genre attribute may be listed, for example, in order from the top of the hierarchy. 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 affiliated shops (Fuji canteen, Asahi fast food), etc. are listed in this order.

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

(Point search procedure of point search device)
Below, the point search process procedure of the point search device 100 is demonstrated using FIG. FIG. 2 is a flowchart showing an example of a point search processing procedure of the point search device 100 according to the present embodiment.

  In the flowchart of FIG. 2, the point search apparatus 100 determines whether 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: loop of No), and when a keyword is input (step S201: Yes), the setting unit 103 sets an attribute to the input keyword (step S202). Thereafter, it is determined from start input unit 104 whether or not an input of search start has been received (step S203).

  It remains in a standby state until it receives an input of search start (step S203: loop of No), and when it receives an input of search start (step S203: Yes), the extraction unit 105 extracts a search item (step S204). Then, it is determined whether there are a plurality of extracted search items (step S205). If it is determined that there are a plurality of search items (step S205: Yes), the presenting unit 106 presents a plurality of search items (step S206).

  Thereafter, in a state where a plurality of search items are presented, the process waits until the selection of the search item is received from the user (step S207: No loop), and when the selection of the search item is received (step S207: Yes) The search unit 109 searches for a point corresponding to the item (step S208). And a search result is output from the output part 110 (step S209), and a series of processes are complete | finished.

  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 is output in step S209. .

  As described above, according to the point search apparatus 100 according to the present embodiment, when there are a plurality of search items, the search items are presented to perform the search, while the search item is the single search item. Since the search is performed without presenting the item, it is possible to present the information necessary for narrowing down at the time of the search to the user and accept the intention of the user in the so-called free keyword search, while presenting the unnecessary information. You can do a search without doing it. Therefore, the number of operations at the time of setting and operation of the search method from the user can be suppressed, and the search results can be presented promptly and accurately, and efficient search can be performed.

  In addition, when there are a plurality of first search items and one second search item for input keywords in which different attributes are set, respectively, the plurality of first search items are presented to the user and searched. It is also possible to conduct a search without presenting the user to a single second search item.

  Thereby, for example, a search is performed using an input keyword of address area attribute related to a large number of place names such as "Fujimi" assumed to be most frequently input from the user and a keyword of genre attribute such as "museum" In the case where “Fujimi” is selected, a search item for specifying which “Fujimi” is specified can be presented to narrow down by the user. Therefore, accurate search results can be presented. On the other hand, for "museum" 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, it is possible to suppress the setting of the search method from the user and the number of operations at the time of operation, and reduce the load on the user at the time of search.

  In addition, when the attribute set in the input keyword is a specific attribute, the search method specified by the specific attribute extracts a search item including the input keyword, while other than the specific attribute When an input keyword with an attribute set is received, if a point corresponding to the input keyword is searched using a 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, the user can be prevented from presenting unnecessary information to the user, and the user's operation input for receiving the search item can be eliminated, and the number of operations can be suppressed. Can reduce the burden of

  Also, if a 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, and the search is performed. Can be done quickly.

  In addition, if a 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 to the input keyword, and a search can be performed quickly and It can do exactly.

  In addition, the present invention can be applied to a point search apparatus having such a multi search function if other attributes include at least one of a name attribute, a Yomi attribute, and a telephone number attribute.

  In addition, if a plurality of search items are listed and presented, search items that are easy for the user to view and understand can be presented. Therefore, the user's erroneous operation can be suppressed, and quick and accurate search can be performed.

  Hereinafter, examples of the present invention will be described. A present Example demonstrates an example at the time of implementing the point retrieval device 100 of this Embodiment by the navigation apparatus mounted in a vehicle.

  In FIG. 4, an attribute table 400 indicates an attribute 401, a keyword 402, and a user selection history 403. The attribute 401 includes an address area attribute for specifying an address area search, a genre attribute for performing a genre search, a name attribute for specifying a name search, and a telephone number attribute for specifying a telephone number search.

  The address area attribute is to search for the address of the point or the area of the point. The genre attribute is to search for a point for the genre of the point. The name search is for searching for a point for the name of the point. The telephone number search is for searching for a point on the point telephone number.

  Although the attribute 401 is not illustrated, it also includes a Yomi attribute or the like for specifying a Yomi search. This Yomi search is for searching for points for Yomi of points, and for searching for keywords entered in katakana or hiragana. Specifically, the Yomi attribute is set when “Tokyo” or “Tokyo” is input as an input keyword for the place name “Tokyo”. In addition, regarding the place name registered beforehand as a hiragana, such as "Saitama", an address area attribute is set with respect to the said hiragana.

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

  Also, a place name is recorded in the address area attribute. That is, all place names existing on the map are recorded in the address area attribute. In addition, as shown to the code | symbol 410, although "name" is recorded on the user selection log | history 403, when "Saitama" 411 is input and this is judged as an address area attribute, a name attribute from a user is set. It shows that it has been changed. Note that this history may be the latest one in the past within a predetermined period, or may be changed many times. Also, the genre attribute stores the genre of the facility, and the business names of affiliated stores and the like are also recorded as the genre.

  In the telephone number attribute, “numbers 0 to 9” is shown as the keyword 402. That is, it indicates that the telephone number attribute is set when a number is input. In addition to the telephone number attribute, a zip code attribute, a map code attribute or the like may be recorded. Further, in these number attributes, priority may be set in setting attributes for the input keyword.

(An example of a search table recorded on a magnetic disk)

(Example of attribute setting process by navigation device)
First, an example of the attribute setting process by the navigation device 300 will be described with reference to FIGS. 6-1 and 6-2 (hereinafter, referred to as FIG. 6). FIG. 6 is a flowchart showing an example of attribute setting processing by the navigation device 300. In addition, in FIG. 6, it is premised that the initial screen at the time of a point search is displayed beforehand by having received selection of a multi search from a user. The input screen will be described later with reference to FIG.

  In FIG. 6, the CPU 301 of the navigation device 300 determines whether 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: loop of No), and when a keyword is input (step S601: Yes), it is judged whether there is a candidate keyword (step S602). The details of the candidate keywords will be described later with reference to FIG. 8. However, for example, “Saitama” 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 the recommended conversion candidate box displayed below the input box (step S603). Then, it is determined whether the selection of the keyword by the user is accepted from the candidate keywords displayed in the recommended conversion candidate box (step S604). When selection of a candidate keyword is received (step S604: Yes), the received candidate keyword is displayed on the input box as an input keyword (step S605). Then, using the attribute table 400 shown in FIG. 4, an attribute is set to the keyword displayed in the input box (step S606).

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

  When the selection of the candidate keyword is not accepted in step S604 (step S604: No), the process proceeds to step S606, and the attribute displayed in the input box is set as the input keyword. If it is determined in step S607 that the keyword is not continuously input (step S607: No), it is determined whether a change in the attribute has been received from the user (step S608).

  If the change of the attribute is received (step S608: Yes), the received attribute is changed (step S609). Then, in addition to the input keyword for which the attribute is set, it is determined whether or not it is accepted that another keyword is to be input (step S610). Specifically, the determination in step S610 is a determination as to whether or not the "add button" shown in FIG. 7 has been selected. On the other hand, when the change of the attribute is not received in step S608 (step S608: No), the process proceeds to step S610.

  If it is determined that the input of another keyword has been received (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, the input of another keyword is accepted (step S612), and the process proceeds to step S602.

  On the other hand, in step S610, when it is not accepted to input another keyword (step S610: No), it is determined whether or not an input of search start is accepted (step S613). It is in a standby state until the input of search start is received (step S613: loop of No), and when the input of search start is received (step S613: Yes), search is performed using a table for each attribute (step S614). The 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 is ended.

(An example of the input screen at the time of point search)
Next, an example of the input screen at the time of the point search will be described using FIG. 7. FIG. 7 is an explanatory view showing 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 syllabary 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 Japanese syllabary Hiragana is listed on the Japanese syllabary key 701, and the touch panel accepts an input from the user. An input box 702 displays the keyword input from the Japanese syllabary key 701.

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

(An example of the display screen when receiving the input of the keyword from the user)
Next, an example of a display screen when receiving an input of a keyword from the user will be described using FIG. 8. FIG. 8 is an explanatory view showing an example of a display screen when receiving an input of a keyword from a 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 as the user inputs “sa” of the Japanese syllabary key 701. In the guess conversion candidate box 703, candidate keywords inferred from "sa" are displayed, and for example, "Saitama" which is a place name, "Circle store" of a convenience store genre, etc. are displayed in addition to "Saga". Be done. Note that this candidate keyword is, for example, a keyword extracted based on the latest history when the user inputs "sa".

  The candidate keyword displayed in the inference conversion candidate box 703 is configured to receive a selection from the user via the touch panel. On this display screen, for example, when the user selects “Saitama” from the inference conversion candidate box 703, the display screen shown in FIG. 9 is displayed.

(An example of display screen when attribute is set to input keyword)
Next, an example of a display screen when an attribute is set to the input keyword will be described with reference to FIG. FIG. 9 is an explanatory view showing an example of a display screen when an attribute is set to the 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 the address area attribute corresponding to "Saitama" is activated and displayed. Further, in the inference conversion candidate box 703, candidate keywords whose input is inferred following “Saitama” are displayed. If it is assumed that the user selects “National Art Museum” from the guess conversion candidate box 703 on this display screen, the display screen shown in FIG. 10 is displayed.

(An example of the display screen when changing the attribute due to the change of the keyword)
Next, an example of a display screen when an attribute is changed due to a change of a keyword will be described with reference to FIG. FIG. 10 is an explanatory view showing an example of a display screen when the attribute is changed due to the change of the keyword. The explanatory diagram shown in FIG. 10 shows the screen displayed in step S606 in the case where there is a continued input (step S607: Yes) in the flowchart shown in FIG.

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

(An example of the display screen when changing the attribute by the user's selection)
Next, an example of the display screen when the attribute is changed by the user's selection will be described using FIG. FIG. 11 is an explanatory view showing an example of the display screen when the attribute is changed by the user's selection. Note that, in the flowchart shown in FIG. 6, the explanatory view shown in FIG. 11 shows the screen displayed in step S609 when there is a continuous input (step S607: Yes).

  In FIG. 11, “Saitama National Art Museum” is set as the genre attribute by the user selecting the item indicating the genre attribute in the attribute tab 704 of the touch panel, and the genre attribute is indicated as indicated by reference numeral 1100. Attributes tab 704 is displayed as active. In addition, it is also possible to set the name attribute again by the user selecting the attribute tab 704 indicating the name attribute on this display screen. In addition, when the attribute tab 704 indicating the address area attribute, the Yomi (temporary name) attribute, or the telephone number attribute is selected, it is possible to set the attribute to the corresponding attribute. For example, even if genre attribute or telephone number attribute is set in "Saitama National Art Museum" and genre search or telephone number search is performed, the search result will be "Not applicable".

  According to the attribute setting process and the display screen described above, the attribute is set to the input keyword, and the point corresponding to the input keyword is searched using the search method specified by the attribute. It is possible to perform a so-called free keyword search that does not require the setting of the search method from the user. Therefore, while being able to reduce the troublesomeness by setting a search method, a user can obtain a suitable search result by reducing the misidentification of a search method.

  Further, since the change of the attribute set in 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, it is possible to obtain appropriate search results reflecting the user's desired attributes.

  In addition, since the history information in which the change of the attribute is accepted is stored, and the attribute is set to the input keyword with reference to the table and the history information, the attribute registered in advance in the table is Even if the user's desired attribute is different, it is not necessary for the user to change the attribute each time, and the user's desired attribute can be set at the time of setting the attribute from next time onwards.

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

(Example of list display processing of search items performed by navigation device)
Next, an example of the process of displaying a list of search items performed by the navigation device 300 will be described with reference to FIGS. 12-1 and 12-2. 12-1 and 12-2 are flowcharts illustrating an example of a process of displaying a list of search items performed by the navigation device 300. In FIGS. 12-1 and 12-2, it is assumed that a single or a plurality of keywords are input and an attribute is already set to the keywords.

  12A, the CPU 301 of the navigation device 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 it receives a search start instruction (step S1201: loop of No), and when a search start instruction is received (step S1201: Yes), the input keyword to which the address area attribute (or genre attribute) is set is It is determined whether there is any (step S1202). Note that, in the case where the genre attribute is set, it will be described below in parentheses.

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

  If it is determined in step S 1204 that the input keyword to which another attribute is set is a genre attribute (step S 1204: YES), search items of the respective attributes are extracted (step S 1205). Then, it is determined whether there is 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 multiple search items in the input keyword for which the address area attribute is set (step S1206: Yes), it is determined whether there are multiple search items in the input keyword for which the genre attribute is set (step S1207).

  If it is determined that there is not a plurality of search items in the input keyword for which the genre attribute is set (step S1207: No), search items for the input keyword in the address area attribute are displayed in a list (step S1208). Then, the process stands by until the selection of the search item is received (step S1209: loop of No), and when the selection of the search item is received (step S1209: Yes), the spot corresponding to the received search item is searched (step S1210). And a search result is displayed (step S1211) and a series of processings are ended. The 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 is a plurality of search items in the input keyword for which the genre attribute is set (step S1207: Yes), the search items for the input keywords in the address area attribute and the genre attribute are sequentially listed and displayed. (Step S1212) It is determined whether the selection of each search item in step S1209 has been accepted.

  If it is determined in step S1206 that the input keyword for which the address area attribute is set does not have a plurality of search items (step S1206: No), that is, if it is determined that the search item is singular, the genre attribute is set. It is determined whether there are a plurality of search items in the input keyword (step S1213). If it is determined that there is a plurality of search items in the input keyword for which the genre attribute is set (step S1213: YES), a list of search items for the input keyword of the genre attribute is displayed (step S1214). It is determined whether or not the selection has been accepted.

  If it is determined in step S1203 that there is no input keyword for which another attribute is set (step S1203: NO), that is, if it is determined that only the input keyword for which the address area attribute or the genre attribute is set. A search item of 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).

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

  On the other hand, if it is determined in step S1216 that there is not a 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 the search items are singular, the list of search items A point corresponding to the input keyword (a single search item) is searched without displaying or the like (step S 1218), and the search result in step S 1211 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 Yomi attribute, the name attribute, or the telephone number attribute is set, the search is performed. A point corresponding to the input keyword in step S1218 is searched without extracting an item or displaying a list. If it is determined in step S1213 that the input keyword for which the genre attribute is set does not have a plurality of search items (step S1213: No), that is, if it is determined that the search item is singular, the search item list is displayed. The point corresponding to the input keyword (search item) in step S1218 is searched without performing the step etc.

In addition, the search item regarding "Asahi convenience store mart" is singular, that is, there is no genre other than "Asahi convenience store mart".

  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. In addition, this shows the case where it transfers to step S1218 from step S1213 of FIGS. 12-1 and 12-2. In other words, when there is not a plurality of search items in each of the input keyword in which the genre attribute is set and the input keyword in which the address area attribute is set, the case of transitioning to the search without displaying the list of search items is shown. There is.

(An example of display screen when attribute is set to multiple input keywords)
Next, an example of a display screen when attributes are set to a plurality of input keywords will be described with reference to FIG. FIG. 13 is an explanatory view showing an example of a display screen when an attribute is set to a plurality of input keywords. The explanatory view shown in FIG. 13 shows the screen displayed in step S611 and step S612 in the flowchart shown in FIG. In addition, the display screen shown in FIG. 13 has shown the screen irrelevant to the keyword shown in FIGS. 8-11, 12-3, 12-4, and 12-5.

  In FIG. 13, input completion boxes 1310 and 1311 are displayed on the display screen. In the input completion box 1310, it is displayed that the address area attribute is set to the input keyword "Saitama". This indicates that the input keyword "Saitama" is input to the input box 702, and the address area attribute is set to the input keyword.

  Furthermore, the input completion box 1311 displays that the genre attribute is set to the input keyword of “Sports”. This indicates that, after “Saitama” is input, the user selects the Add button 705 and the input keyword “Sports” is input, whereby the genre attribute is set to the input keyword. .

  Further, on this display screen, an input keyword of "Urawa" is input in the input box 702, and as shown by reference numeral 1320, an attribute tab 704 indicating a name attribute is displayed in an active state. Although the address area attribute is originally set for the keyword "Urawa", the name attribute is set here. This is because “Saitama” has already been registered as the address area attribute, and therefore, it is set in advance not to accept the input of the address attribute. Even when the address area attribute is already registered, it is possible to set again in advance to be able to receive the input of the address area attribute.

  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 for each of the set attributes for the three input keywords. The details of the search process will be described below with reference to FIGS. 14-1, 14-2, and 15.

(An example of the details of the search process by the navigation device)
Next, an example of the search process by the navigation device will be described in detail with reference to FIGS. 14-1, 14-2, and 15. FIG. 14A is a flowchart of an example of area code extraction processing in the point search processing. The flowchart illustrated in FIG. 14A illustrates a process of extracting an area code from an input keyword in which an address area attribute is set. In FIG. 14-1, assuming that the display screen shown in FIG. 13 is used, that is, the address area attribute is set to the input keyword of “Saitama”, and the genre attribute is set to the input keyword of “Sports”, It is assumed that the name attribute is set to the input keyword of "Urawa".

  In FIG. 14A, the CPU 301 of the navigation device 300 collates the input keyword (“Saitama”) in the address area with the address name in the address table 520 shown in FIG. 5-1 (step S1401). Then, it is determined whether there is a match as a result of the comparison (step S1402). If it is determined that there is a match (step S1402: YES), an area code "11100" (see reference numeral 514 in FIG. 5-1) 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 numbers in the buffer are numbers defined for the sake of convenience for each search result by each attribute. On the other hand, if it is determined in step S1402 that no match is found as a result of the collation (step S1402: No), the invalid value is stored in the buffer 1 (step S1405), and the series of processing is ended. In addition, an invalid value shows that there is no point applicable to the said input keyword.

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

  In FIG. 14-2, the CPU 301 of the navigation device 300 collates the input keyword (“the stadium”) of the genre name with the genre name in the genre table 530 shown in FIG. 5-1 (step S1411). Then, it is determined whether or not there is a match as a result of the comparison (step S1412). If it is determined that there is a match (step S1412: YES), the 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 no match is found as a result of the collation (step S1412: No), the invalid value is stored in the buffer 2 (step S1415), and the series of processing is ended.

  FIG. 15 is a flowchart showing 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 extraction process of the area code shown in FIG. 14-1, and the genre code extraction process shown in FIG. Shows a process of specifying a facility using the specified genre code.

  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. 5-1 (step S1502). Then, it is determined whether there is a match as a result of the comparison (step S1503). If it is determined that there is a match (step S1503: YES), the matched point information is extracted, and a search table is created (step S1504). The details of the search table will be described later with reference to FIG.

  Furthermore, after this, 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 comparison (step S1507). If it is determined that there is a match (step S1507: YES), the matched point information is extracted, and a search table is re-created (step S1508).

  Then, the input keyword ("Urawa") of the facility name is collated with the facility name in the search table re-created in step S1508 (step S1509). Then, it is determined whether there is a match as a result of the comparison (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). Then, the point information stored in the buffer 3 is output as a search result (step S1512), and the series of processing is ended.

  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 spot information table 510 (step S1503: No), output that there is no corresponding spot information. (Step S1513), the series of processing is ended. If it is determined in step S1507 that the genre code and the genre code in the search table do not match (step S1507: NO), the process proceeds to step S1513. If it is determined in step S1510 that the input keyword of the facility name and the facility name in the re-created search table do not match (step S1510: NO), the process proceeds to step S1513. Do.

(An example of a search table created in search processing)
Next, an example of a search table created in the search process will be described using FIG. FIG. 16 is an explanatory diagram of an example of a search table created in the search process.

  In FIG. 16, in the first search table 1610, when there is a match between the acquired area code "11100" and the area code in the point information table 510 shown in FIG. 5-1. The table which extracted the matched point information is shown. That is, the first search table 1610 indicates facility information when the area code “11100” (“Saitama”) is extracted from the point information table 510.

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

  The search result 1630 extracts the matched point information when there is a match between the input keyword ("Urawa") of the facility name and the facility name in the second search table 1620. Show the search results that are output. That is, the search result 1630 indicates facility information including the characters “urawa” in the second search table 1620. That is, it indicates that “Urawa Stadium” is output as the search result 1630.

  In the above description, the area search for creating the first search table 1610, the genre search for creating the second search table, and the name search for extracting location information from the second search table are performed in this order. 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.

(An example of the display screen when the search result is output)
Next, an example of the display screen when the search result is output will be described using FIGS. 17 and 18. FIG. 17 is an explanatory diagram of 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 the address of “Urawa Stadium” and the like as the search result. Further, on the search result screen 1710, a selection button 1711 for receiving an input as to whether or not to set “Urawa Stadium” as a destination is displayed. When the user selects “Yes” among the selection buttons 1711, “Urawa Stadium” is set as a destination.

  On the map screen 1720, maps of the surroundings are displayed centering on "Urawa Stadium". In the 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. The display screen when a plurality of search results are displayed will be described below with reference to FIG.

  FIG. 18 is an explanatory diagram of 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. For example, when "Urawa Stadium" is selected by the user on this display screen, the display screen shown in FIG. 17 is displayed. In addition, also when other points other than "Urawa stadium" are selected by the user, similarly, it shifts to a display screen on which each search result screen and map screen are displayed.

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

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

  In addition, when there are a plurality of first search items (search items of address area attribute) and one second search item (search item of genre attribute) with respect to input keywords in which different attributes are set, respectively, The plurality of first search items are presented to the user for search, and the single second search item is searched without being presented to the user.

  Specifically, as shown in FIG. 12-4, a search is performed using input keywords of address area attributes related to a large number of place names such as "Fujimi" and keywords of genre attributes such as "Asahi convenience store". In the case of performing "Fujimi", a search item for specifying which "Fujimi" is can be presented to narrow down by the user. Therefore, accurate search results 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, it is possible to suppress the setting of the search method from the user and the number of operations at the time of operation, and reduce the load on the user at the time of search.

  In addition, when the attribute set in the input keyword is a specific attribute, the search method specified by the specific attribute extracts a search item including the input keyword, while other than the specific attribute When an input keyword with an attribute set is received, a 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 → refer to step S1218), and presentation or non-presentation of a search item can be performed according to the attribute of the input keyword. Therefore, according to the attribute of the input keyword, the user can be prevented from presenting unnecessary information to the user, and the user's operation input for receiving the search item can be eliminated, and the number of operations can be suppressed. Can reduce the burden of

  Further, 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, and the search is performed. Can be done quickly.

  In addition, since a 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 to the input keyword, and a search can be performed quickly and It can do exactly.

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

  Further, since a plurality of search items are listed and presented (see FIG. 12-4), search items that are easy for the user to view and understand can be presented. Therefore, the user's erroneous operation can be suppressed, and quick and accurate search can be performed.

  As described above, according to the program, the search program, the search device, the search system, the facility search device, and the facility search system of the present invention, when performing a search using a plurality of keywords, which keyword corresponds to which search method It is not necessary for the user to determine whether the information is applicable, and the burden on the user at the time of search can be reduced.

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