Abstract

PROBLEM TO BE SOLVED: To correct a registration spot database according to an update content of a facility database.SOLUTION: A confirmation object setting section 105 sets registration spot information for confirming whether a correction is necessary from a registration spot database 220 storing the registration spot information. A search section 101 searches facility information to become a correction candidate of the registration spot information of a confirmation object by searching the facility information in a facility database 211 regularly or irregularly updated under search conditions set for the registration spot information of the confirmation object. A registration correction section 106 corrects the registration spot information of the confirmation object by the facility information selected as the correction candidate.

Description

  The present invention relates to a technique for managing registration point information registered due to a user operation.

  The navigation device provides the user with functions such as route search and guidance using various data in the map database. The map database stores information about various facilities and provides the information to the user.

  Conventionally, updating the map database has required replacing all data in the map database. However, recently, due to technological progress, it is possible to implement differential data updating only for data that needs to be updated in the map database. Many techniques for updating the map database have been proposed (see Patent Document 1 below).

JP 2008-59045 A

  When the map database is updated, there are cases where inconvenience arises in the use of registered spot information registered by the user in the navigation device. For example, facility relocation and parking lot movement are updated in the map database, but are not reflected in the registration point database for the user. For this reason, when a guidance point is set from the registration point database for the user, a desired facility does not exist at the arrival point. Also, the user knows the transfer of the facility for the first time at the arrival point. Then, the user is forced to perform a new search and re-registration work.

  The same applies even if the guidance point is set from the point information stored as the search and use history. That is, the point information recorded in the history is the same as the registered point information registered by the user in that it cannot receive the benefits of updating the map database.

  Further, for example, before a newly opened facility is recorded in the map database, the user may register the location information of the point. However, even if the map database is subsequently updated, the registration point database for the user is not updated. For this reason, even if, for example, the map database contains detailed information about the facility, the user cannot know the detailed information from the registered point database for the user. Then, the user is forced to perform a new search and re-registration work.

  New search and re-registration operations require labor and time if the number of registered registration points is large.

  An object of the present invention is to provide an information management technique suitable for reflecting an update of information in another database on registered point information registered due to a user operation.

  An information management apparatus according to an aspect of the present invention relates to an information management apparatus that manages registration point information registered due to a user operation. The information management device includes a registration target setting unit that sets registration point information for confirming the necessity of correction from a registration point database that stores registration point information, and a facility that is regularly or irregularly updated. A search unit that searches facility information in the database under the search conditions set for the registration point information to be checked to search for facility information that is a correction candidate for the registration point information to be checked, and a correction candidate. A registration correction unit that corrects the registration point information to be confirmed according to the facility information selected as.

  According to the said one form, according to the update content of a facility database, a registration point database can be correct | amended. For this reason, the inconvenience of using an old registration point database can be eliminated. Moreover, if all corrections to the registration point database are performed manually, it takes labor and time, but such labor and time can be reduced.

  The objects, features and advantages of the present invention will become more apparent from the following detailed description and the accompanying drawings.

1 is a block diagram illustrating an information management apparatus according to Embodiment 1. FIG. 5 is a flowchart for explaining a correction processing flow according to the first embodiment. 5 is a block diagram illustrating an information management apparatus according to Embodiment 2. FIG. 10 is a block diagram illustrating an information management apparatus according to Embodiment 3. FIG.

  In the following, an embodiment of an information management device according to the present invention will be described. The information management device can be realized in a navigation device, for example. Note that the navigation device is mounted on a moving body such as an automobile vehicle, a railway vehicle, an aircraft, and a ship. However, the moving body may be a person, and the navigation device may be of a type that can be carried by a person (so-called PND (Portable Navigation Device)).

  The information management apparatus can also be realized in a PDA (Personal Digital Assistant) such as a mobile phone, a smartphone, or a tablet terminal. In that case, the PDA may or may not have a navigation function. In view of this point, the information management apparatus can be realized in various apparatuses having a so-called information processing function regardless of the presence or absence of the navigation function, and whether or not it is a portable type.

<Embodiment 1>
FIG. 1 shows a block diagram of an information management apparatus 10 according to the first embodiment. In the example of FIG. 1, the information management apparatus 10 includes a control unit 100, a storage unit 200, a display unit 11, an input unit 12, a communication unit 13, and a recording medium reading unit 14.

  The control unit 100 performs various processes in the information management apparatus 10. Here, the control unit 100 includes a central processing unit (for example, configured with one or a plurality of microprocessors) and a main storage unit (for example, one or a plurality of storage devices such as ROM, RAM, flash memory, etc.). ). According to this example, various processes are executed by the central processing unit executing various programs stored in the main storage unit. Various processes can be executed in parallel. Various functions corresponding to the various processes are realized.

  The program executed by the central processing unit may be stored in advance in the main storage unit, or may be read from the storage unit 200 during execution and stored in the main storage unit. The main storage unit is used not only for storing programs but also for storing various data. In addition, the main storage unit provides a work area when the central processing unit executes the program.

  Here, various functions of the control unit 100 are realized by software, but all or some of the various functions of the control unit 100 are realized by hardware (for example, an arithmetic circuit configured to perform a specific calculation). May be.

  The storage unit 200 stores various information. Here, the storage unit 200 is provided as an auxiliary storage unit used by the control unit 100. The storage unit 200 can be configured using, for example, one or more storage devices such as a hard disk device, a rewritable and nonvolatile semiconductor memory, and an optical disk.

  In the example of FIG. 1, the storage unit 200 is provided with a map database 210 and a registration point database 220. Note that “database” may be referred to as “DB”.

  The map DB 210 is a database in which various data related to map information is stored. The map DB 210 includes a plurality of databases, and includes, for example, a terrain information database, a road network information database, and a railway network information database.

  Further, in the example of FIG. 1, the map DB 210 includes a facility database 211 in which information on various facilities is collected. The facility information of each facility includes name and location information, and may further include information such as a telephone number, a genre, business hours, a regular holiday, and a URL address. As the position information, latitude and longitude are assumed here, but an address may be adopted instead of or in addition to the latitude and longitude. In addition, a facility is sufficient if it is a specific place, and shall be interpreted broadly. For example, not only a place where a building exists but also a place where a building does not exist such as a square corresponds to a facility.

  The map DB 210 (in other words, each database such as the facility DB 211) is updated by the producer of the map DB 210 or the like. For example, when update data is supplied from a server on a communication network (Internet, LAN (Local Area Network), etc.), the information management apparatus 10 acquires the update data via the communication unit 13. Further, for example, when update data is supplied by an external recording medium (SD memory card, optical disc, etc.), the information management apparatus 10 acquires the update data via the recording medium reading unit 14. And the information management apparatus 10 updates map DB210 in the memory | storage part 200 with the acquired update data.

  In general, update data is supplied as appropriate (in other words, as necessary), so the map DB 210 is also updated accordingly. That is, the map DB 210 is updated regularly or irregularly.

  The registered spot DB 220 is a database that stores registered spot information registered due to user operations. For example, when the user searches the map DB 210 and designates a specific point from the search results, information related to the designated point is stored in the registered point DB 220 as registered point information. Further, for example, the user may specify a registration point on a map displayed on the screen without using the search function.

  For example, the user may designate the current location as a registration point (so-called current location registration). Specifically, position information of the current location is acquired from a position detection function such as a navigation device, and the position information is included in the registered point information.

  In addition, for example, information on points automatically stored by the information management apparatus 10 as user operation history (points listed in search results, points used by users as guidance points, etc.) is registered. As point information, you may store in registration point DB220.

  The registered spot information automatically registered by the information management device 10 may be managed in the same database as the registered spot information registered by the user's designation, or may be managed in a separate database. In the latter case, the registration point DB 220 is composed of these two databases.

  Each registered point information includes name and position information, and may further include information such as a telephone number, a genre, business hours, a regular holiday, and a URL address. As the position information, latitude and longitude are assumed here, but an address may be adopted instead of or in addition to the latitude and longitude.

  When a registered point is selected from the facilities in the facility DB 211, the registered point information can have the same information by copying the facility information. On the other hand, according to the current location registration, for example, the position information can be automatically recorded in the registration point information, but the user inputs the name information. Alternatively, the reference number of the registration point information (in other words, the ID number) is substituted as the name information.

  The display unit 11 displays information supplied from the control unit 100. The display unit 11 can be configured by various display devices such as a liquid crystal display device. The input unit 12 receives a user operation. The input unit 12 can be configured by various input devices such as a touch panel, a keyboard, a mouse, and the like.

  The communication unit 13 mediates communication between the control unit 100 and a device existing outside the information management device 10 (for example, a server that supplies update data of the map DB 210). The communication unit 13 can be configured by various communication devices, and the communication may be either a wired method or a wireless method, or may be a combination of a wired method and a wireless method. In the wireless system, not only radio signals but also optical signals may be used.

  The recording medium reading unit 14 reads data recorded on an external recording medium (SD memory card, optical disk, etc.) and transfers the data to the control unit 100. The recording medium reading unit 14 can be configured by various reading devices.

  Note that the configuration of the information management apparatus 10 is not limited to the example of FIG. For example, any one of the communication unit 13 and the recording medium reading unit 14 may be omitted. 1 illustrates an example in which the display device is included in the information management device 10 as the display unit 11, a display device externally connected to the information management device 10 may be used. The same applies to the input unit 12 and the like. Conversely, other components may be added to the configuration illustrated in FIG. When the information management device 10 is incorporated in a car navigation device, for example, a position detection unit is connected to the control unit 100, and the control unit 100 also functions as a navigation execution unit.

  Below, the control part 100 is demonstrated more concretely. In the example of FIG. 1, the control unit 100 provides a search unit 101, a spot registration unit 102, a facility DB update unit 103, a correction start instruction unit 104, a confirmation target setting unit 105, and a registration correction unit 106. To do.

  The retrieval unit 101 retrieves data in the database (in particular, facility information in the facility DB 211 here). The search key, in other words, the search condition is given by the user, for example.

  The spot registration unit 102 registers spot information in the registration spot DB 220. Specifically, the spot registration unit 102 stores the spot information in the registration spot DB 220 in accordance with the spot designation by the user. Moreover, the point registration part 102 selects a point from a user's operation history, and stores the point information in registration point DB220.

  The facility DB update unit 103 acquires update data of the facility DB 211 from a server or an external recording medium, and updates the facility DB 211 with the update data. When the update data is supplied from the server, the server may notify the facility DB update unit 103 that the update data has been prepared, or the facility DB 211 may inquire of the server whether there is update data.

  The correction start instruction unit 104 controls the start of a correction process flow for correcting information in the registration point DB 220 according to information in the facility DB 211 (specifically, updated information).

  Note that the expression “update” used for the facility information and the facility DB 211 (in other words, the map information and the map DB 210) may be used for the registered spot information and the registered spot DB 220, but the explanation is easy to understand. Therefore, the expression “correction” is used for the registration point information and the registration point DB 220.

  Specifically, the correction start instruction unit 104 activates the confirmation target setting unit 105, the search unit 101, and the registration correction unit 106 according to a predetermined start condition.

  The start condition is, for example, a condition (first start condition) that the user has instructed correction confirmation of the registration point DB 220.

  For example, when the user clicks or taps the correction confirmation button on the screen, the first start condition is satisfied. In addition, for example, the first start that the user sets an external recording medium in which the update data of the facility DB 211 is recorded in the recording medium reading unit 14, in other words, such an external recording medium is detected. You may adopt as a condition. Further, for example, the fact that the correction confirmation time set in advance by the user may be adopted as the first start condition. Further, for example, the first start condition may be set by combining these examples.

  The start condition is, for example, a condition that the facility DB 211 has been updated (second start condition). The correction start instruction unit 104 can know the completion of the update of the facility DB 211 by a notification from the facility DB update unit 103. Alternatively, the correction start instruction unit 104 may inquire the facility DB update unit 103 about the completion of the update of the facility DB 211.

  The correction start instruction unit 104 starts the correction process flow of the registration point DB 220 when one of the first start condition and the second start condition is satisfied. Alternatively, the correction process flow may be started when both the first start condition and the second start condition are satisfied.

  According to the first start condition, the user can control the start of the correction process flow. That is, the correction process flow can be started at a timing desired by the user. It is also possible to prevent the correction process flow from automatically starting at a timing not desired by the user. For example, if the correction processing flow is activated during a route search before departure, the processing load on the control unit 100 may increase and the route search may take time.

  According to the second start condition, it is possible to prevent the correction process flow from being started under a situation where the facility DB 211 is not updated. That is, the correction process flow can be executed efficiently.

  The confirmation target setting unit 105 sets registration point information for confirming the necessity of correction from the registration point DB 220. The confirmation target is set according to a user instruction or automatically.

  The registered spot information set as the confirmation target (more specifically, each item constituting the registered spot information) is used as a search key in the search unit 101. That is, the search unit 101 searches the facility DB 211 to search for facility information that is a correction candidate for the registration point information to be confirmed.

  The registration correction unit 106 corrects the registration point information to be confirmed based on the facility information selected as the correction candidate.

  The functional block of the control unit 100 is not limited to the example of FIG. For example, even if the point registration unit 102 is omitted, a correction function for registered point information can be realized. Other functional blocks may be added.

  FIG. 2 shows a correction processing flow ST10 of the registration point DB 220. The correction process flow ST10 is started by an instruction from the correction start instruction unit 104.

  First, in step ST11, registration point information of a target for confirming whether correction is necessary is set from the registration point DB 220. For example, a list of registered spot information (for example, a list of names) stored in the registered spot DB 220 is displayed on the display unit 11 and the user is prompted to perform an input operation to select registered spot information to be set as a confirmation target. Then, the registration point information selected by the user using the input unit 12 is set as a confirmation target. Step ST11 is executed by the confirmation target setting unit 105, for example.

  Next, in step ST12, a search condition for searching the facility DB 211 is set. For example, settable search conditions are displayed on the display unit 11 and the user is prompted to perform an input operation to set the search conditions. The search conditions set by the user using the input unit 12 are used in the next search step ST13. Step ST12 is executed by the search unit 101, for example.

  The search condition is, for example, a condition (first search condition) for searching for facility information similar to the registration point information to be confirmed.

  Specifically, the condition that the registered spot information and facility information are similar (similar condition) is that the contents of some items (name, location, phone number, genre, etc.) included in the registered spot information are It is satisfied by matching the contents of the same item included in the information. A complete match or a partial match may be applied to the content match determination level. For example, the similarity may be quantitatively evaluated based on the match rate using the concept of speech recognition. The determination level of content matching may be the same for all items, or may be different for each item. Moreover, it is preferable that the user can set the determination level of content matching, and according to this, it is possible to provide a search that matches the user's feeling.

  Note that a condition (matching condition) that the registration point information and the facility information match may be added to the first search condition. The matching condition is satisfied when the contents of all items included in the registration point information completely match the contents of the same item included in the facility information. For example, when the match rate is equal to or higher than a preset threshold, it may be determined that the names match.

  When this matching condition is satisfied, the same facility information as the confirmation target registration point information is extracted from the facility DB 211. In that case, it may generally be difficult to assume that the registration point information to be confirmed is corrected by the extracted facility information. However, providing such a search result to the user may be able to inform the user of the reliability of the registration point information to be confirmed.

  The search condition is a condition (second search condition) for searching for facilities existing in an area set to include a point indicated by position information included in registration point information to be confirmed. Note that the second search condition may be called a range search condition.

  According to the second search condition, for example, facility information that is difficult to extract under the first search condition can be extracted. For example, if the number of search target items is reduced in the first search condition, the processing load on the control unit 100 can be reduced, but extraction with high accuracy may be difficult. More specifically, when only the name is set as the search target item, the facility whose name has been changed significantly may not be extracted according to the first search condition. Further, for example, the same applies when the location of the facility is changed beyond the similarity range that can be set by the first search condition.

  In addition, it is preferable that the area | region set to a search range can be set by the user. For example, the density of facilities differs between urban areas and mountain areas. The ease of finding a desired facility is considered to depend on the number of facilities presented to the user, and the number of presentations can be adjusted to the user's preference.

  According to the first search condition and the second search condition, facility information that cannot be extracted only by the matching condition can be extracted. Thereby, more correction candidates of registration point information can be presented to the user, and information useful for the user's judgment can be provided. In addition, as a cause which cannot be extracted only by matching conditions, it can be considered that, for example, in the registration point information, the name is registered as an abbreviated name and is registered including an error.

  Only one of the first search condition and the second search condition can be applied, or both of them can be applied.

  After step ST12, the search unit 101 in step ST13 searches the facility information in the facility DB 211 under the search conditions set for the confirmation target registration point information, thereby obtaining the confirmation target registration point information. Search for facility information as candidates for correction. If at least one piece of facility information that satisfies the search condition is extracted as a result of the search, the at least one piece of facility information becomes a correction candidate. On the other hand, if the facility information that satisfies the search condition is not extracted, there is no correction candidate in the facility DB 211.

  In the next step ST14, the search result of step ST13 is presented to the user. Specifically, the facility information extracted as a correction candidate is displayed on the display unit 11, and the user is prompted to perform an input operation to select facility information to be used for correcting registered spot information. The facility information of the correction candidates may be displayed as a list in a list format, or may be displayed on the map so that the position is indicated. Alternatively, if no correction candidate is found, this is displayed on the display unit 11. Step ST14 is executed by the search unit 101, for example.

  The user selects one of the proposed correction candidate facility information (step ST16), but in the correction processing flow ST10 illustrated in FIG. 2, the search condition can be changed before that (step ST16). ST15). That is, in step ST15, a change in search conditions is accepted. According to this, the presented search results can be narrowed down, or the search can be performed again with another search condition. Step ST15 is executed by the search unit 101, for example.

  When the user instructs to change the search condition (step ST15), the process by the control unit 100 returns to step ST12. On the other hand, when the user performs a selection operation on the facility information presented as the correction candidate, the selection operation is received via the input unit 12 (step ST16). In step ST17, the registration point information to be confirmed is corrected based on the facility information selected by the user. Steps ST16 and ST17 are executed by the registration correction unit 106, for example.

  With the end of step ST17, the correction process flow ST10 ends.

  Here, in the above, in step ST11, the user sets registration point information to be confirmed. On the other hand, the confirmation target setting unit 105 may automatically set the confirmation target. For example, the confirmation target setting unit 105 sets the registration point information to be confirmed according to a predetermined setting rule. As a setting rule, for example, a rule that preferentially selects registration point information that has not been corrected before, a rule that preferentially selects the correction date and time from the oldest, and a priority on registration point information that has not been used recently The rule of choosing to be considered. These rules may be combined.

  Regardless of whether the setting in step ST11 is performed manually or automatically, if there are a plurality of registration point information to be confirmed, the correction process flow ST10 may be executed for each registered point information.

  In step ST11, if all the registration point information in the registration point DB 220 is automatically and sequentially set as confirmation candidates, the total processing time may be increased. In such a case, for example, confirmation candidates may be narrowed down in advance by the setting rule.

  In the above description, in step ST16, the user selects facility information used for correction. On the other hand, for example, the search unit 101 or the registration correction unit 106 may automatically select. For example, the facility information with the highest accuracy is automatically selected from the facility information extracted as the correction candidates. However, it is considered that the judgment by the user can obtain higher accuracy and is more suitable for the user's subjectivity than originally.

  According to the information management device 10 and the correction processing flow ST10, the registration point DB 220 can be corrected according to the update contents of the facility DB 211. For this reason, the inconvenience of using old registration point DB220 can be eliminated.

  For example, even when a guide point is set from registered point information, it is possible to prevent arrival at an old (in other words, undesired) point. For example, even if the facility before being recorded in the facility DB 211 is registered in the registration point DB 220, the facility information recorded thereafter can be taken into the registration point DB 220.

  Further, if all the corrections of the registration point DB 220 are performed manually, labor and time are required. However, according to the information management apparatus 10 and the correction processing flow ST10, such labor and time can be reduced.

<Embodiment 2>
In the example of FIG. 1 according to Embodiment 1, the information management apparatus 10 has a map DB 210. However, as shown in FIG. 3, the map DB 210 may exist outside the information management apparatus 10. For example, the map DB 210 is stored in a server provided outside the information management apparatus 10. In this case, the information management apparatus 10 can execute the correction processing flow ST10 by accessing the map DB 210 via the communication unit 13, as in the first embodiment. As a result, various effects similar to those of the first embodiment can be obtained.

  Here, when the map DB 210 exists outside the information management apparatus 10, the facility DB 211 is updated outside the information management apparatus 10. For this reason, the facility DB update unit 103 can be omitted from the information management apparatus 10 (see FIG. 3). The second start condition (condition that the facility DB 211 is updated) applied to the correction start instruction unit 104 can be determined by a notification from the server storing the facility DB 211, an inquiry to the server, or the like. .

  Here, not the entire map DB 210 but a part of the database including the facility DB 211 may be provided outside the information management apparatus 10.

  Further, instead of or in addition to the facility DB 211 (or the map DB 210), the registration point DB 220 may be provided outside the information management apparatus 10. The registration point DB 220 may be stored in the same server as the facility DB 211 (or the map DB 210), or may be stored in a separate server.

<Embodiment 3>
In the first embodiment, an example in which the registration point DB 220 is corrected using the facility DB 211 has been described. On the other hand, you may correct | amend registration point DB220 using another registration point DB. Such an example is shown in FIG. In the block diagram illustrated in FIG. 4, the registration point DB 220 described in the first embodiment is called a first registration point DB 220, and the other registration point DB is called a second registration point DB 320.

  That is, in the description of the first embodiment, “registration point DB 220” and “registration point information” are read as “first registration point DB 220” and “first registration point information”, respectively, and “facility DB 211” and “facility” By replacing “information” with “second registration point DB 320” and “second registration point information”, Embodiment 3 can be understood. Also according to the third embodiment, various effects similar to those of the first embodiment can be obtained.

  In the example of FIG. 4, the second registration point DB 320 is provided outside the information management apparatus 10. Specifically, the second registration point DB 320 is stored in a server, and the information management apparatus 10 can access the second registration point DB 320 via the communication unit 13. Alternatively, the second registration point DB 320 is stored in an external recording medium, and the information management apparatus 10 can access the second registration point DB 320 via the recording medium reading unit 14.

  On the other hand, the second registration point DB 320 may be used after being copied or moved from the server or the external recording medium into the storage unit 200 of the information management apparatus 10. The second registration point DB 320 may be newly created in the information management apparatus 10. That is, in view of these examples, the correction processing flow ST10 may be executed in a state where the second registration point DB 320 is provided in the information management apparatus 10 together with the first registration point DB 220.

  In addition, the user of 2nd registration point DB320 may be the same as the user of 1st registration point DB220, and may differ.

  Here, for example, the facility type of the facility DB used to create the first registered spot information may be different from the type of item in the facility information of the facility DB used to create the second registered spot information. . However, since any registered point information has position information (for example, latitude and longitude information), the first registered point information and the second registered can be obtained by setting a search condition mainly using the position information. It is possible to associate with point information.

<Modification>
The present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
