The generated modification table is stored in the storage unit 118.

  In S262, the modification table generating unit 104 determines whether there is data for which the modification type has not yet been identified in the text data table. If it is determined that there is data that does not identify the type of modification (YES in S262), the process proceeds to S264. If not (NO in S262), the process ends. In S264, the modification table generating unit 104 acquires the next data in the text data table.

  Referring to FIG. 5, the program executed by information search device 100 performs the following control regarding search.

  In S1400, search key input unit 110 detects a search key based on the operation detected by operation unit 108. In the present embodiment, the search key input unit 110 regards a character string in a range specified by the user via the operation unit 108 among the documents displayed in the document unit 130 as a search key. In the case of the present embodiment, when a modified character string is included in the search key, the search key input unit 110 considers that the character “*” is designated instead of the modified character (note that In an embodiment different from the present embodiment, instead of assuming that the character “*” is specified, it may be considered that another character is specified). The character “*” is a character used for wild card search. The search key input unit 110 detects that the modified character string is included in the search key by comparing the range specified by the user via the operation unit 108 with the data included in the modification table.

  In S1402, condition generation unit 112 generates a search condition based on the search key. This process corresponds to each process of S14200 to S14228 described later.

  In S1404, based on the search condition generated by search key and condition generation unit 112, processing unit 114 searches the text data table for a character string that matches the search key. In the case of the present embodiment, the processing unit 114 searches the character string matching the search key from the data in the text data table by sequentially comparing the search key and the data in the text data table.

  Referring to FIG. 6, the program executed by condition generation unit 112 performs the following control with respect to generation of search conditions.

  In S14200, condition generation unit 112 initializes a search condition. In this step, “initialize search conditions” means that five types of searches, “front match”, “backward match”, “partial match”, “wildcard search”, and “complete match” should be performed. This means generating information to that effect. Note that “forward matching” in the present embodiment refers to searching for a character string in which a part of the character string including the beginning matches the search key. “Backward match” in the present embodiment refers to searching for a character string in which a part of the character string including the end matches the search key. “Partial match” in the present embodiment refers to searching for a character string in which any part of the character string matches the search key. “Wild card search” in the present embodiment refers to searching for a character string in which any part of the character string matches a character string other than the character represented by “*” in the search key. “Completely match” in the present embodiment refers to searching for a character string in which all of the character strings match the search key.

  In S14202, condition generation unit 112 refers to the data stored in storage unit 118 to determine whether a modification table exists. If it is determined that there is a modification table (YES in S14202), the process proceeds to S14204. If not (NO in S14202), the process ends. In S14204, condition generation unit 112 obtains the first modification table from storage unit 118. In S14206, condition generation unit 112 acquires the first modification data from the modification table.

  In S14208, condition generation unit 112 acquires a search key from search key input unit 110. When the search key is acquired, the condition generation unit 112 displays a qualified character string (a character string to be subjected to character modification. In this step, the qualified character string includes the modified data acquired by the condition generation unit 112. It is determined whether or not the search key and the search key match. If it is determined that the qualified character string matches the search key (YES in S14208), the process proceeds to S14209. If not (NO in S14208), the process proceeds to S14210.

  In S14209, the condition generation unit 112 changes the search condition to information indicating that the search is prohibited.

  In S14210, condition generation unit 112 determines whether the distance from the search key to the qualified character string is equal to or less than the threshold and the range matching the search key is before the position of the qualified character string. This “position” means the position of the qualified character string in the document. “Document” means a document represented by document data. In this embodiment, “distance from search key to qualified character string” corresponds to the number of characters existing between the range that matches the search key and the range in which the character string is actually modified. It means the distance to be. In the case of this embodiment, it is assumed that the above-described threshold value is zero. Thereby, the condition generation unit 112 determines whether or not the range that matches the search key is adjacent to the position of the qualified character string. If it is determined that the range matching the search key is adjacent to the position of the qualified character string (YES in S14210), the process proceeds to S14212. If not (NO in S14210), the process proceeds to S14214. In S14212, the condition generation unit 112 deletes information indicating that a “forward match” search is to be performed and information indicating that a “partial match” search is to be performed from the search conditions generated in S14202.

  In S14214, condition generation unit 112 determines whether the distance from the search key to the qualified character string is equal to or smaller than the threshold and the range matching the search key is behind the position of the qualified character string. This “position” also means the position of the character string with modification in the document. The meaning of “document” is also the same. The meaning of “distance from search key to character string with modifier” is also the same. Thereby, the condition generation unit 112 determines whether or not the range that matches the search key is adjacent to the position of the character string with the modification. If it is determined that the distance from the search key to the qualified character string is equal to or smaller than the threshold and the range matching the search key is after the position of the qualified character string (YES in S14214), the process proceeds to S14216. It is. If not (NO in S14214), the process proceeds to S14218. In S14216, condition generation unit 112 deletes information indicating that a “backward match” search should be performed and information indicating that a “partial match” search should be performed from the search conditions generated in S14200. As a result, when the search key is after the qualified character string, the condition generation unit 112 sets the search condition so that the forward match, complete match, and wild card search are used as the search conditions.

  In S14218, condition generation unit 112 determines whether or not the search key includes a qualified character string. If it is determined that a character string with a modification is included (YES in S14218), the process proceeds to S14220. If not (NO in S14218), the process proceeds to S14222. In S14220, condition generation unit 112 deletes information indicating that “wild card search” should be performed from the search conditions generated in S14200.

  In S14222, condition generation unit 112 determines whether there is modification data that has not yet been used for the search. If it is determined that there is decoration data (YES in S14222), the process proceeds to S14224. If not (NO in S14222), the process proceeds to S14226. In S14224, condition generation unit 112 acquires the next modification data from the modification table.

  In S14226, condition generation unit 112 determines whether there is a modification table that is not yet used for the search. If it is determined that a modification table exists (YES in S14226), the process proceeds to S14228. If not (NO in S14226), the process ends. In S14228, condition generation unit 112 acquires the next modification table.

  Referring to FIG. 7, the program executed by information search apparatus 100 performs the following control regarding the display of the explanatory text.

  In S2204, display modification table generating unit 116 generates an explanatory modification table. This process corresponds to the processes of S2400 to S2422 described later. In S2206, creation unit 120 creates display data according to the explanatory modification table. When the display data is created, the explanation unit 134 displays the explanation according to the display data.

  In S2208, display modification table generating unit 116 determines whether or not all the explanatory data has been displayed. If all the explanatory data is displayed (YES in S2208), the process ends. If not (NO in S2208), the process proceeds to S2210. In S2210, display modification table generating unit 116 acquires the following explanation data.

  Referring to FIG. 8, the program executed by display modification table generating unit 116 performs the following control with respect to generation of the modification table.

  In S2400, display modification table generating unit 116 acquires data. The acquired data varies depending on the modification table to be created. For example, when creating the explanation modification table, the acquired data is explanation data about the search key included in the explanation table stored in the storage unit 118.

  In S2402, the display modification table generation unit 116 refers to the storage unit 118 to determine whether a modification table exists. If it is determined that the modification table exists (YES in S2402), the process proceeds to S2404. If not (NO in S2402), the process ends. In S2404, display modification table generating unit 116 acquires the first modification table.

  In S2406, display modification table generating unit 116 determines whether or not the same character string as the character string represented by the acquired explanation data exists in the modification table. If it is determined that the same character string exists (YES in S2406), the process proceeds to S2408. If not (NO in S2406), the process proceeds to S2424. In S2408, display modification table generating unit 116 acquires modification data corresponding to the character string represented by the acquired description data.

  In S2410, display modification table generating unit 116 determines whether or not the modification type represented by the modification data is a mask. If it is determined that the modification type is a mask (YES in S2410), the process proceeds to S2412. If not (NO in S2410), the process proceeds to S2416.

  In S2412, display modification table generating unit 116 determines whether or not the modification state represented by the modification data is “present”. If it is determined that the decoration state is “present” (YES in S2412), the process proceeds to S2414. If not (NO in S2412), the process proceeds to S2416. In S2414, display modification table generating unit 116 registers new modification data in the modification table being created.

  In S2416, display modification table generating unit 116 determines whether or not the modification type represented by the modification data is a text box. If it is determined that the modification type is a text box (YES in S2416), the process proceeds to S2418. If not (NO in S2416), the process proceeds to S2420.

  In S2418, display modification table generating unit 116 determines whether or not a character is input in the text box. If it is determined that no character has been input (YES in S2418), the process proceeds to S2420. If not (NO in S2418), the process proceeds to S2414.

  In S2420, display modification table generating unit 116 determines whether there is still modification data. If it is determined that there is decoration data (YES in S2420), the process proceeds to S2422. Otherwise (NO in S2420), the process proceeds to S2424. In S2422, the display modification table generating unit 116 acquires the next modification data.

  In S2424, display modification table generating unit 116 refers to storage unit 118 to determine whether or not a modification table still exists. If it is determined that there is a modification table (YES in S2424), the process proceeds to S2426. If not (NO in S2424), the process ends.

In S2426, display modification table generating unit 116 acquires the next modification table.
The operation of the information search apparatus 100 based on the structure and flowchart as described above will be described.

[When the character string immediately before the masked character string matches the search key]
A process when the character string immediately before the masked character string matches the search key will be described.

  The document data input unit 102 acquires document data. In this case, the content of the search key is “Tokugawa”. The document data input unit 102 passes the acquired document data to the storage unit 118 (S200). The storage unit 118 stores document data. In the case of the present embodiment, the document data includes a text data table and an explanation table.

  FIG. 9 shows the data structure of the text data table and the contents of the data. Referring to FIG. 9, the text data table includes “data position”, “data type”, “XY position”, “data”, “modification”, and “state”. By including “modification” and “state”, the text data table includes character modification data for the character string represented by “data”.

  “Data position” is information for specifying “data” in the text data table. In the case of the present embodiment, “data position” represents the number of data corresponding to the head of the text data table.

  “Data type” is information indicating whether “data” is character string data or image data. In the present invention, the character string data is data of a character string constituting a document. In the present embodiment, when “data” is character string data, the text data table includes a value “0” as “data type”. When “data” is image data, the text data table includes a value “1” as “data type”.

  The “XY position” is information representing a set of values of the X coordinate and the Y coordinate on the screen of the display 142. In the case of the present embodiment, the X coordinate and Y coordinate of the screen of the display 142 are set at the upper left corner of the screen.

  “Data” is data constituting a document. When the value of “data type” is “0”, the text data table includes character string data as “data”. When the value of “data type” is “1”, the text data table includes image data as “data”.

  “Modification” is data representing the type of character modification for the character string represented by “data”. When masking is performed on “data”, the text data table includes character string data “mask” as “modification”. When the document unit 130 displays a character string designated by the user instead of “data”, the text data table includes character string data “text box” as “modification”.

  “State” is data representing the state of character modification for the character string represented by “data”. In the case of the present embodiment, if the text data table includes character string data “mask” as “modification” and character string data “present” as “state”, “data” represents. A mask is attached to the character string. In the case of the present embodiment, if the text data table includes character string data “mask” as “modification” and character string data “none” as “state”, “data” represents the data. No modification is added to the string.

  In the case of the present embodiment, if the text data table includes character string data “text box” as “modification” and some data is included as “state”, “state” is used instead of “data”. "Is displayed as a character string represented by the data included. In the case of this embodiment, when “data” is image data, the text data table has a character string “non” as “modification” (information indicating that no modification is made to “data” in this embodiment). )including. However, this does not mean that the character string “non” is essential information. In embodiments other than the present embodiment, when “data” is image data, the text data table may not include special information as “modification”.

  When the document data is acquired, the modification table generating unit 104 acquires the first data of the text data table (S250). In the case of the present embodiment, the acquired data is data having a “data position” value of “1”. When the data is acquired, the modification table generating unit 104 determines whether the modification type, that is, the content of “modification” in the test data table is other than “non” (S252). In this case, since the content of “modification” is “mask” (YES in S252), the modification table generating unit 104 determines whether there is a modification table corresponding to “modification” (S254). In this case, since there is no modification table (NO in S254), the modification table generating unit 104 newly generates a modification table corresponding to the modification type “mask” (S260).

  When the modification table is generated, the modification table generation unit 104 registers the data position and the like in the modification table (S258). The processes of S258 and S260 indicate that the modification table generation unit 104 generates a modification table for each type of character modification by combining data included in the text data table. When the data position and the like are registered, the modification table generating unit 104 determines whether there is data for which the modification type has not yet been identified (S262). In this case, since such data exists (YES in S262), the modification table generation unit 104 acquires the next data (S264). When data is acquired, the processing from S252 to S264 is repeated.

  FIG. 10 is a diagram showing the contents of the modification table created and stored in the storage unit 118. In the case of the present embodiment, the modification table includes “modification”, “data position”, “data type”, “XY position”, “data”, and “state”. “Modification” to “State” are the same as those in the text data table shown in FIG. Since “data” is included, the decoration table is a data table including character string data. Since “data” and “state” are included, the character string represented by the data included in the modification table is a character string to be subjected to character modification.

  When the modification table is generated, the creation unit 120 creates display data (S204). When the display data is created, the document unit 130 displays the contents of the display data (S206). Thereby, the document unit 130 displays the document based on the text data table.

  When the display data is displayed, the operation unit 108 determines whether a user operation (excluding a search request) has been performed (S208). In this case, if there is a search request (NO in S208), operation unit 108 determines whether there is a search request (S212). In this case, since it is determined that a search request has been made (YES in S212), search key input unit 110 is a search key that is a character string that the user wants to search from a document based on the user's operation. Is detected (S1400). When the search key is acquired, the condition generation unit 112 initializes the search condition (S14200). When the search condition is initialized, the condition generation unit 112 determines whether a modification table exists (S14202). In this case, since the modification table exists (YES in S14202), the condition generation unit 112 acquires the first modification table (S14204). When the modification table is acquired, the condition generation unit 112 acquires the first modification data (S14206). In this case, in the first modification table, the content of “modification” is “mask”. The first modification data is modification data whose “data position” value is “1”. When the modification data is acquired, the condition generation unit 112 determines whether or not the character string with modification (character string subject to character modification) matches the search key (S14208). In this case, the content of the search key is “Tokugawa” and the content of the character string with the modifier is “ABC”. As a result, since the qualified character string does not match the search key (NO in S14208), condition generation unit 112 determines whether the range that matches the search key is adjacent to the position of the qualified character string. It is determined whether or not (S14210). In this case, since the qualified character string is not adjacent to the search key “Tokugawa” (NO in S14210), the condition generation unit 112 has a range that matches the search key after the position of the qualified character string. It is determined whether or not they are adjacent to each other (S14214). In this case, the qualified character string is not adjacent to the search key “Tokugawa” (NO in S14214), and therefore the condition generation unit 112 determines whether or not the search key includes a qualified character string (S14218). ). In this case, since the search key does not include a character string with modification (NO in S14218), condition generation unit 112 determines whether there is modification data that has not yet been used for search (S14222). In this case, since the modification data still exists (YES in S14222), the condition generation unit 112 acquires the next modification data (S14224).

  When the decoration data is acquired, the processes of S14208 to S14224 are repeated. After the process is repeated, when the modification data whose content of “data” is “Ieyasu” is acquired, the condition generation unit 112 determines that the range matching the search key is before the position of the qualified character string. It is determined whether or not they are adjacent (S14210). Thereby, the condition generation unit 112 determines whether or not the distance from the search key to the qualified character string is equal to or smaller than the threshold value and the search key is in front of the qualified character string in the document. This “document” means a document represented by document data. In this case, since the range that matches the search key is adjacent to the position of the qualified character string (YES in S14210), condition generation unit 112 performs a search for “forward match” from the search condition. The information indicating that the information indicating that the search should be performed and the information indicating that the “partial match” search should be performed are deleted (S14212). Thereby, the condition generation unit 112 sets the search condition so that the search condition is a backward match, complete match, and wildcard search when the search key is in front of the character string to be character-modified. Will be. By the processing of S14208 to S14212, the condition generation unit 112 sets a restriction on the search. In the case of the present embodiment, the condition generation unit 112 sets a search condition as a restriction on the search according to the position of the search key in the document with respect to the qualified character string. “Document” means a document represented by document data.

  When the information is deleted, the processing of S14208 to S14224 is repeated through the processing of S14222 to S14224. Thereafter, when there is no modification data that is not yet used for search (NO in S14222), condition generation unit 112 determines whether there is a modification table that is not yet used for search (S14226). In this case, since there is a modification table whose “modification” is “text box” (YES in S14226), condition generation unit 112 acquires the next modification table (S14228). When the modification table is acquired, the processes of S14208 to S14224 are repeated. Thereafter, it is determined again whether there is a modification table that is not used for the search (S14226). In this case, since there is no such modification table (NO in S14226), processing unit 114 executes a search (S1404). As a result, when the search key input unit 110 detects the search key, the processing unit 114 restricts the search set by the condition generation unit 112 (in this embodiment, “restriction for search” is the search condition). The character string including the search key is searched from the text data table.

  When the search is executed, the creation unit 120 determines whether there is a search result (S216). In this case, since there is a search result (YES in S216), creation unit 120 creates display data representing the search result. The result unit 132 displays the search result (character string including the search key) based on the display data created by the creation unit 120 (S218). When the search result is displayed, the operation unit 108 determines whether or not there is a request to display an explanatory text (S220). In this case, if there is no such request (NO in S220), operation unit 108 determines whether or not to end the search (S224). In this case, when the search ends (YES in S224), the process ends. FIG. 11 is a diagram showing a screen of display 142 on which the search result is displayed in S228. Since there is a character string consisting only of “Tokugawa” in a portion of the text data table not shown, “Tokugawa” is displayed.

[If no search results are found]
Processing when the search result is not found will be described.

  After the processing unit 114 executes the search (S1404), the creation unit 120 determines whether there is a search result (S216). In this case, since there is no search result (NO in S216), creation unit 120 creates display data indicating that the search result is not found. The result unit 132 displays that the search result is not found (S226). FIG. 12 is a diagram showing a screen of display 142 when a character string that matches the search key is not included in an unmodified word.

[When only the character string including the masked character matches the search key]
Processing when a character string including a masked character matches a search key will be described.

  When a character string in which the “Japanese parent” part of the “Japan-US US-Japan Treaty” is masked is designated as the search key, the processing of S14208 to S14224 is repeated after the processing of S200 to S14206. After that, if the qualified character string acquired in S14208 is “Japan-US Treaty of Peace”, “Japan-US Trade Treaty”, “Japan-US Good Trade Treaty”, or “Japan-US Security Treaty”, etc., Through the processing of S14208 to S14214, the condition generation unit 112 determines whether or not the search key includes a qualified character string (S14218). Since it is determined that the search key includes a qualified character string (YES in S14218), condition generation unit 112 deletes information indicating that “wild card search” should be performed from the search condition (S14220). Thereby, when the search key includes a character string with a modification, the condition generation unit 112 sets the search condition so that the search condition is a forward match, a backward match, a partial match, and a complete match. .

  Thereafter, after the processes of S14222 to S14224 and S14208 to S14228 are repeated, the processing unit 114 executes a search (S1404). When the search is executed, the creation unit 120 determines whether there is a search result (S216). In this case, since the search result is not found (NO in S216), creation unit 120 creates display data indicating that the search result is not found. The result part 132 displays that the search result is not found (S226). FIG. 13 is a diagram showing a screen of display 142 when “Japan-US Treaty of Peace” is selected as a search key. FIG. 14 is a diagram showing the screen of the display 142 when a word matching the search key is not found other than the modified characters as a result of selecting “Japan-US Treaty of Peace” as the search key. FIG. 15 is a diagram showing a display screen when a search result of a conventional information search apparatus is displayed.

[When displaying explanatory text]
A description will be given of processing in a case where an explanatory text is displayed, and the same text string as the masked text string is included in the text data.

  FIG. 16 is a diagram showing the contents of the explanation table according to the present embodiment. In the present embodiment, the “explanation table” is a data table of explanatory text data representing an explanatory text about a word. The storage unit 118 stores an explanation table together with the text data table. Although a part of the explanatory text data is shown in the “data” column of FIG. 16, the actual explanatory text data is not data representing only the explanatory text shown in FIG.

  When “Sekigahara” is designated as the search key, after the processing of S200 to S218, the operation unit 108 determines whether or not there is a request for display of the explanatory text (S220). Thereby, the operation unit 108 detects a word that the user desires to display the explanatory text based on the user's operation. In this case, since operation unit 108 determines that there is a request for display of an explanatory note (YES in S220), display modification table generation unit 116 uses the explanation table stored in storage unit 118 to search for the search key. Explanation data is acquired (S2400). When the explanation data is acquired, the display modification table generating unit 116 determines whether or not a modification table exists (S2402). In this case, if there is a modification table (YES in S2402), display modification table generating unit 116 acquires the first modification table (S2404). When the modification table is acquired, the display modification table generating unit 116 determines whether or not the same character string as the character string represented by the acquired explanation data exists in the modification table (S2406). In this case, since such a character string exists (YES in S2406), display modification table generating unit 116 acquires modification data corresponding to the acquired character string (S2408).

  When the modification data is acquired, the display modification table generating unit 116 determines whether “modification” is “mask” (S2410). In this case, if “modification” is set to “mask” (YES in S2410), display modification table generating unit 116 determines whether “status” is “present” (S2412). In this case, if the “state” is “present” (YES in S2412), the display modification table generating unit 116 registers the modification data in the modification table being created (in this case, the modification table for explanation) (S2414). . As a result, the display modification table generating unit 116 generates an explanation modification table. In the case of the present embodiment, the explanatory modification table is the same as the character string represented by the data in the modification table, the character string represented by the data in the modification table, for the data representing the specific explanatory text in the explanatory text data. It is generated so as to be subject to the same character modification. In the present embodiment, the “description modification table” is a data table composed of character modification data for a character string constituting a specific description. The “specific explanation” is an explanation about a word that the user desires to display an explanation. In the case of this embodiment, the structure of the explanatory modification table is the same as the structure of the modification table. Therefore, the description of the explanation modification table will not be repeated here.

  When the modification data is registered, the display modification table generating unit 116 determines whether the modification data still exists (S2420). In this case, since the modification data still exists (YES in S2420), display modification table generation unit 116 acquires the next modification data (S2422).

  When the modification data is acquired, the processes of S2410 to S2422 are repeated. After that, since there is no modification data (NO in S2420), the display modification table generating unit 116 determines whether there is still a modification table (S2424). In this case, since the modification table still exists (YES in S2424), the display modification table generating unit 116 acquires the next modification table (S2426). When the modification table is acquired, the processes of S2410 to S2422 are repeated through the processes of S2406 and S2408. After that, the display modification table generating unit 116 determines whether there is still a modification table (S2424). In this case, if there is no modification table (NO in S2424), creation unit 120 creates display data according to the description modification table. When the display data is created, the explanation unit 134 displays an explanatory text according to the display data created by the creation unit 120 (S2206). Thus, the explanation unit 134 displays the specific explanation according to the content of the data included in the explanation modification table.

  When the explanatory text is displayed, the creating unit 120 determines whether all the explanatory data is displayed (S2208). If all the explanation data is displayed (YES in S2208), operation unit 108 determines whether or not to end the search (S224). FIG. 17 is a diagram showing a screen of display 142 when an explanatory text is displayed. The description is also modified in the same way as the document.

  As described above, the information search apparatus according to the present embodiment limits the display of the search conditions and search results according to the contents of the displayed document, thereby Display of content that is not performed can be prevented. Since it is possible to prevent display of contents not intended by the user, it is possible to provide an information search apparatus suitable for the purpose of learning.

  The text data table may include “byte position” instead of “XY position”. The “byte position” includes information indicating the position of data represented by “data” in the document represented by the text data table by the number of bytes. FIG. 18 is a diagram illustrating the structure of the text data table when “byte position” is included instead of “XY position”.

  Further, data exchange between the devices of the information search device 100 may be performed not only via the bus 158 but also via a communication cable or a wireless communication device that can transmit and receive data. Each device of the information search device 100 is not limited to the CPU 140, and may be realized by a DSP (Digital Signal Processor) or a logic circuit in which a processing procedure is taken as a circuit.

  In addition to the mouse 148, the tablet 152, and the keyboard 150, hardware that specifically implements the information search apparatus 100 may use various input devices such as voice input using a microphone and instructions using buttons.

  The speaker 154 may be a device that receives only a control signal of on / off, not a sound signal, and outputs a predetermined sound.

  Further, the main storage device 144 may be a memory or a register included in the CPU 140.

  The external storage device 146 may be a device attached to another network device. The “other network device” in this paragraph is a device connected to the CPU 140 via a network in a wired or wireless manner.

  If it is determined in S220 that a description text display request has been made, the creation unit 120 determines whether the character string representing any part of the specific explanation text is the same as the character string represented by the data in the modification table. It may be determined whether or not. The “specific explanation” is an explanation about a word that the user desires to display the explanation. When making such a determination, the creation unit 120 prohibits the display of the specific explanatory text if the character string representing any part of the specific explanatory text is the same as the character string expressed by the data in the modification table. Display data to the effect may be created. By creating such display data in place of the display data of the explanatory text, the creating unit 120 causes the character string representing any part of the specific explanatory text to be the same as the character string represented by the data of the modification table In this case, a restriction that prohibits the display of the specific explanatory text is set. Since the description unit 134 displays information represented by the display data, when the operation unit 108 detects a word, the specific description is displayed unless there is a restriction that prohibits the display of the specific description. .

  Further, the text data table may include “relative position from the beginning of the document” instead of “XY position”. The “relative position from the beginning of the document” is the position of each character constituting the document when the document represented by the document data is printed on one sheet of paper. The number of lines and the number of characters per line when the document is printed on one sheet of paper are not particularly limited. The method of determining the origin of “relative position from the beginning of the document” is not particularly limited. However, an example of how to determine the origin includes a method in which the origin occupies the position occupied by the first character among the characters constituting the document.

  In S14210 and S14214, the “distance from the search key to the qualified character string” is the number of morphemes that exist between the range that matches the search key and the range in which the character string is actually modified. May be. Note that “morpheme” means the smallest unit that has meaning in a language. The condition generation unit 112 can specify the number of morphemes by performing morpheme analysis. Since a specific method of morphological analysis is well known, detailed description thereof will not be repeated here.

<Second Embodiment>
Hereinafter, an information search apparatus according to the second embodiment of the present invention will be described.

  The hardware configuration of the information search apparatus according to the present embodiment is the same as that of the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 19, the program executed by information search device 100 performs the following control regarding generation of search conditions. In the flowchart shown in FIG. 19, the same step numbers are assigned to the processes shown in FIG. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In S14230, condition generation unit 112 determines whether or not the qualified character string includes a search key. If it is determined that the search key is included (YES in S14230), the process proceeds to S14234. If not (NO in S14230), the process proceeds to S14232.

  In S14232, condition generation unit 112 determines whether or not the search key includes a qualified character string. If it is determined that a character string with a modification is included (YES in S14232), the process proceeds to S14234. If not (NO in S14232), the process proceeds to S14222. In S14234, condition generation unit 112 changes the search condition to information indicating that the search is prohibited.

  The operation of the information search apparatus 100 based on the structure and flowchart as described above will be described.

  It is assumed that “Tokugawa” is selected as a search key. Through the processing up to S14204, the condition generation unit 112 acquires the first modification data (S14206). When the modification data is acquired, the condition generation unit 112 determines whether the qualified character string includes a search key (S14230). In this case, if the qualified character string does not include the search key (NO in S14230), condition generation unit 112 determines whether or not the search key includes the qualified character string (S14232). If the search key does not include a qualified character string (NO in S14232), the processes of S14230 to S14224 are repeated through the processes of S14222 to S14224. Thereafter, when the qualified character string is “Ieyasu Tokugawa”, condition generating unit 112 determines that the qualified character string includes the search key (YES in S14230), and therefore condition generating unit 112 sets the search condition as the search condition. (S14234). Thus, the condition generation unit 112 sets a restriction that prohibits the search when at least a part of the qualified character string matches at least a part of the search key. In the present embodiment, “at least a part of the qualified character string and at least a part of the search key match” means that the qualified character string includes the search key, and the search key is character-modified. It corresponds to one of cases where the target character string is included.

  When the search condition is changed, the processing unit 114 executes a search (S1404). In this case, since the search condition is information indicating that the search is prohibited, the processing unit 114 does not perform the actual search. In this way, the condition generation unit 112, if the search key input unit 110 detects the search key, the character string including the search key from the text data table, unless there is a restriction that prohibits the search. Will be searched. When the search is completed without performing an actual search, the creation unit 120 determines whether there is a search result (S216). In this case, since there is no search result (NO in S216), creation unit 120 creates display data indicating that the search result is not found. The result unit 132 displays that the search result is not found based on the display data created by the creation unit 120 (S226).

  As described above, the information search apparatus according to the present embodiment displays that the search is not permitted when the search target character is masked. Thereby, the display of the content which a user does not intend can be prevented.

  In S14234, instead of changing the search condition, the condition generating unit 112 restricts display to be prohibited when at least a part of the qualified character string matches at least a part of the search key. It may be set. In this case, the condition generation unit 112 generates a signal for prohibiting the display of the search result in order to set a constraint that prohibits the display. The condition generation unit 112 transmits a signal for prohibiting display of the search result to the creation unit 120. When the signal for prohibiting the display of the search result is transmitted, the creation unit 120 creates display data indicating that the display of the search result is prohibited. The result unit 132 displays a message that the display of the search result is prohibited. As a result, the result section 132 displays the character string including the search key unless there is a restriction that prohibits the display. FIG. 20 is a diagram showing a screen of display 142 on which a message indicating that the search is not permitted is displayed.

  Further, instead of a message that the search result is not found, a message that the search result is not displayed may be displayed because a mask is included. FIG. 21 is a diagram showing a screen of display 142 in such a case.

<Third Embodiment>
Hereinafter, an information search apparatus according to the third embodiment of the present invention will be described.

  The hardware configuration of the information search apparatus according to the present embodiment is the same as that of the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 22, the program executed by information search device 100 performs the following control regarding search. In the flowchart shown in FIG. 22, the same step numbers are assigned to the processes shown in FIG. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In S230, each unit of information search device 100 displays the search result. This process corresponds to each process of S2302 to S2312, which will be described later.

  Referring to FIG. 23, the program executed by each unit of information search apparatus 100 performs the following control regarding display of the search result.

  In S 2302, display modification table generation unit 116 acquires the search result from storage unit 118. In S2304, display modification table generating unit 116 reads the first data of the search results.

  In S2306, display modification table generation unit 116 generates a display modification table. This process corresponds to each process of S2400 to S2426.

  In S2308, the creation unit 120 refers to the search result stored in the storage unit 118 and the display modification table, and displays the display data so that the same character modification as the data included in the text data table is performed. create. The result unit 132 displays the search result based on the display data created by the creation unit 120.

  In S2310, display modification table generating unit 116 determines whether there is still a search result. If it is determined that there is a search result (YES in S2310), the process proceeds to S2312. If not (NO in S2312), the process ends.

  An operation of information search apparatus 100 based on the above structure and flowchart will be described.

  It is assumed that “Tokugawa” is selected as a search key. Through the processing up to S214, the display modification table generating unit 116 acquires the search result (S2302). FIG. 24 is a diagram illustrating a data table of data to be searched in the present embodiment. A data table of data to be searched is stored in the storage unit 118. The data table of data to be searched includes “data position”, “reading”, “notation”, “first”, and “last”. The “data position” is information for specifying each data in the data to be searched. In the case of the present embodiment, a value indicating what number data is in the search result is included as “data position”. “Reading” is information representing the reading of the character string retrieved by the processing unit 114. In the case of the present embodiment, it is assumed that reading is defined in advance in the text data table for each word constituting the document. “Notation” is information representing a character string that is a search target by the processing unit 114. “Head” is a value representing the head of positions in the document of the character string to be searched by the processing unit 114. “Last” is a value representing the last of the positions in the document of the character string that is the search target of the processing unit 114.

  When the search result is acquired, the display modification table generating unit 116 reads the data of the first search result (S2304). FIG. 25 shows the structure of the search result data table. The search result data table includes “number”, “data position”, “reading”, and “notation”. “Number” is information for specifying each data in the data to be searched. Others are the same as the data table of the data to be searched.

  When the search result is read, the display modification table generating unit 116 generates a display modification table (S2306). In the case of the present embodiment, the display modification table generating unit 116 adds the same character modification as the character string represented by the modification table data to the same character string represented by the modification table data among the character strings including the search key. Is associated with the data representing the character string, the display modification table, which is a data table of data representing the character modification of the character string including the search key, is generated.

  FIG. 26 shows the contents of the display modification table. The structure of the display modification table according to the present embodiment is the same as that of the modification table according to the first embodiment.

  When the display modification table is generated, the result unit 132 displays the search result (character string including the search key) according to the data content included in the display modification table (S2308). FIG. 27 is a diagram illustrating a screen of display 142 when a search result is displayed. Search results are also modified in the same way as documents.

  As described above, the information search apparatus according to the present embodiment can apply the same modification to the search result as the document. Thereby, the display of the content which a user does not intend can be prevented.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
