[0032] The retrieval device according to the first embodiment of the present invention is applied to a navigation system equipped for a vehicle. figure 1 It is a block diagram showing the overall configuration of a navigation system 1 serving as a retrieval device.

[0033] The navigation system 1 is mainly composed of a control unit 10 . An operation switch 20 , a map data storage unit 30 , a predicted keyword storage unit 35 , a current position calculation unit 40 , a speaker 50 , a display 60 and the like are connected to the control unit 10 . The control unit 10 is formed as a computer including a CPU, ROM, RAM, input / output ports, and a bus connecting the above elements. The control unit 10 handles the control of the entire system. The operation switch 20 is formed of a contact switch integrated with the display 60, a mechanical switch, a remote control unit, etc., and is used for various input operations. In the present embodiment, the operation switch 20 includes a ...

[0055] will refer to Figure 10 and Figure 11 A retrieval device according to a second embodiment of the present invention will be described. This example is only Figure 5 The processing of S106 is different from that of the first embodiment. Thus, only differences from the first embodiment will be described, and descriptions of other configurations, processes, and the like will be omitted. When the delete button 73 is selected and the input character is deleted, there is a high possibility that the user intended to select surrounding characters (ie, characters at input positions arranged around the deletion character in the input character table 71 ), but the user mistakenly selects the deletion character. Therefore, in this embodiment, in Figure 5 In S106, the predetermined numerical value for reducing the score is set in the column corresponding to the deleted character at the deleted character position in the deleted character management table 81, and the deleted ch...

[0060] will refer to Figure 12 to Figure 14 A retrieval device according to a third embodiment of the present invention will be described. This embodiment differs from the first embodiment in processing for extracting prediction candidate character strings. Thus, only differences from the first embodiment will be described, and descriptions of other configurations, processes, and the like will be omitted. will refer to Figure 12 The flowchart shown in describes the prediction candidate character string extraction processing according to the third embodiment. Figure 12 The flow chart shown in is only on S107 with Figure 5 The flowchart shown in is different, so that only the processing of S107 will be described, and the description of the processing of other steps will be omitted.

[0061] exist Figure 12 In S107 in , when the numerical value for changing the score is set at the character position after the deleted character position, the numerical value is updated. ...

Abstract

The present invention proposes a searching device comprising an input string acquisition unit that acquires an input string input by a user, a predicted candidate string extracting unit that extracts a predicted candidate string that begins with the input string, a deleted character determining unit that acquires a deleted character deleted from the input string, and that determines a deleted character position that is a character position of the deleted character in the input string, and a changing unit that, on the basis of the deleted character and the deleted character position, changes a priority of the predicted candidate string that begins with the input string from which the deleted character has been deleted.

Description

[0001] incorporation by reference [0002] The entire disclosure of Japanese Patent Application No. 2010-262098 filed on Nov. 25, 2010 including specification, drawings and abstract is hereby incorporated by reference. technical field [0003] The invention relates to a retrieval device, a retrieval method and a computer-readable storage medium. Background technique [0004] In the prior art, there is known a retrieval device that retrieves words and the like including an input character string based on a character string input by a user's operation. Incidentally, characters not intended by the user may be input by a user's erroneous operation. The technique described in Japanese Patent Application Laid-Open No. 2007-140900 (JP-A-2007-140900) does not accept an input operation of a character for which a correction instruction has been issued so as not to input an erroneous character again. Contents of the invention [0005] However, the technique described in JP-A-2007-1...
