摘要： PROBLEM TO BE SOLVED: To update a learned keyword in conjunction with update of location information. SOLUTION: A navigation device includes a technology that learns a history of operations in a location information search (a POI search). The navigation device learns, as learned keywords, search terms that a user has input, and the next time that the user inputs a search character string, the navigation device supports the user's search term input operation by presenting a learned keyword that matches the search character string and letting the user select it. The navigation device deletes and updates location information in conjunction with closings and the like of facilities, but it also deletes the learned keywords that it has learned for the purpose of searching for the corresponding location information. This makes it possible to prevent a situation in which location information has been deleted and cannot be searched even though the user has selected and input the learned keyword. When a location name is altered, the search key after the alternation can be added to the learned keyword. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：结合更新位置信息来更新学习的关键字。解决方案：导航设备包括一种学习位置信息搜索（POI搜索）中的操作历史的技术。导航装置作为学习的关键字学习用户输入的搜索词，并且下一次用户输入搜索字符串时，导航装置通过呈现与搜索字符匹配的学习关键字来支持用户的搜索词输入操作字符串并让用户选择它。导航装置结合设施的关闭等删除和更新位置信息，但也删除了为了搜索对应的位置信息而学习的学习关键词。这使得可以防止哪个位置信息被删除并且即使用户已经选择并输入了学习的关键字也不能被搜索的情况。更改位置名称后，可以将更改后的搜索键添加到学习关键字。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a data processing device, a data processing method and a data processing program which can search for and update data easily even if the number of files constructing the data is small.SOLUTION: A data processing device 6 comprises a search information DB12 storing at least data constructed by hierarchical structure of plural data tables and an identification unit 9 determining top position of the data table for search. The search information DB12 stores the data table in a same system in an order from high-order class to low-order class. Each of plural data tables contains identification information to discriminate the data table of the low-order class uniquely, next column size and subordinate size. The identification unit determines a relative position to the top position of the data table for identification by adding subordinate size from the data table of the high-order class to the data table stored in a storage position just before the data table for identification.

摘要： PROBLEM TO BE SOLVED: To provide a technique for taking stronger security measures in a navigation system wherein map data are transferred to a navigation unit via a rewritable recording medium. SOLUTION: Update right information necessary for updating map data is recorded in a rewritable data area of a recording medium 4 with map data recorded therein. At the first time of data access to the recording medium 4 by the navigation unit 1, the update right information is read from the data area while being deleted from the data area. A map update deadline prepared based on the update right information read out is written into a memory of the navigation unit together with medium identification information read from an unrewritable management area.

摘要： PROBLEM TO BE SOLVED: To perform reading/writing by reducing memory capacity for storing pieces of data or records and minimizing deterioration of a response of the reading.
SOLUTION: In this data list reader/writer which reads many pieces of data stored according to an application 2, and sequentially writes desired pieces of data to create a freely readable specific data list, a plurality of pieces of data are sequentially stored in specific positions without associating offsets with them in a storage part 5 of data without offset, the offsets are associated with an offset table 6 which is linked to the storage part 5 of the data without offset at predetermined data intervals, and when the desired pieces of data are selected from the specific data list, a nearby offset is selected from the offset table 6, the number of pieces of data is calculated to the number of desired pieces of data based on the offset, the desired pieces of data are read from a reading/writing part 7, a memory region for information on the offset is omitted, the memory capacity can be reduced, the response which hardly makes a person recognize a sense of incongruity of deterioration of the response is attained.

摘要： PROBLEM TO BE SOLVED: To control keyword display based on a guidance history.
SOLUTION: A navigation apparatus 1 guides a vehicle to a destination, and then determines whether the vehicle has moved from the destination (namely, whether the vehicle has stopped at the destination). When a user inputs characters on a retrieval word input screen 100, the navigation apparatus displays a keyword corresponding to the character on a keyword button 104, or the like. In that case, the navigation apparatus determines whether the vehicle has not moved from the last destination. When the vehicle has not moved from the last destination, the navigation apparatus searches spot information of the destination, searches the spot information, and prevents a keyword without searching other pieces of spot information from being displayed, thus allowing the navigation apparatus to improve convenience of retrieval word input by keywords without displaying any keywords for selecting spot information of a spot where the vehicle stops currently.

摘要： PROBLEM TO BE SOLVED: To enhance security concerning map data in a navigation system comprising an update unit for downloading map data in order to update the map data of a rewritable recording medium detachable from and attachable to a navigation unit. SOLUTION: In this navigation system, the update unit has an update encoding key. Map data for update are transferred to the recording medium and recorded thereon by the update unit. Hash values generated from at least part of the map data are transferred as map security data to the recording medium and recorded thereon. Medium identification information and the security data or map security processed data acquired by processing the security data, are encoded with the update encoding key. What are thus acquired are transferred as updated security data to the recording medium and recorded thereon. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To increase the amount of information which can be accumulated in a sub-database by making the capacity of a field in which offsets are stored smaller than a conventional manner.
SOLUTION: A variable length offset rewriting device rewrites offsets by storing offsets in a base section B with specified data length including: a base data area B2 as a data area from a low order digit; and an extension flag area B1 in which an extension flag is set when any extended data area other than the base data area B2 is used, and storing the residual offsets which have not been stored in the base data area B2 in an extension section E as a data area. When the extension flag is not set, the data stored in the base data area B 2 are obtained as offsets, and when the extension flag is set, the data stored in the base data area B2 and the data stored in the extension section E are connected and obtained as offsets and a sub-database is accessed.
