Description

  The present invention relates to an information display control device and an information display control program.

  2. Description of the Related Art Conventionally, an electronic dictionary device as a kind of information display control device includes a dictionary database that stores each headword and explanation information in association with each other, and provides explanation information of the headword corresponding to an inputted character. It reads out from a dictionary database, and displays a headword and explanatory information.

In recent years, such electronic dictionary devices have various functions such as a text display function, a word book function, and a jump function.
Here, the text display function is a function for displaying text data stored therein by downloading or the like.
The word book function is a function that facilitates review by registering part or all of a desired headword and corresponding explanation information in the word book (for example, see Patent Document 1).

  In addition, the jump function is a function in which when a user selects a word in the text while text such as explanatory information is displayed, a headword corresponding to the word is searched. For example, when the jump function is executed while the explanation information of a certain headword is displayed, a desired word in the display screen is newly searched for, that is, jumped according to the operation of the cursor key or the enter key. After being selected as a target, the explanation information of the headword corresponding to this word is retrieved from the dictionary database, and the headword and the explanation information are displayed (for example, refer to Patent Document 2).

By the way, there are cases where a plurality of similar words having similar appearances are scattered in the text displayed on the electronic dictionary device. Therefore, it is necessary to reorganize the understanding contents by confirming the existence of similar words or by examining the semantic contents of each similar word as necessary. Therefore, from the viewpoint of improving the understanding level of the text, when there are a plurality of similar words in the text, it is preferable that the presence of these similar words and the difference in semantic content can be confirmed at a desired timing.

FIG. 8 is a flowchart for explaining the operation of the information display process in which the CPU 6 reads the information display control program 81 from the flash ROM 8 and executes it.

<Keyword extraction process>
As shown in FIG. 7, first, when the text data 830 is downloaded to the flash ROM 8 or the external information storage medium 12a via the transmission control unit 3, the CPU 6 selects a word in the text represented by the text data 830. After the extraction, the headword corresponding to the word is read from each dictionary database 820, and the headwords are arranged in alphabetical order and stored in the text headword table 850 (step T1).

  At this time, the CPU 6 may read the headword only with the dictionary database 820 designated in advance by the user and store it in the headword table 850 in the text, or each headword in the dictionary database 820. By referring to the difficulty level table that associates the difficulty level with the difficulty level, only the headwords having a predetermined difficulty level or higher may be stored in the headword table 850 in the text.

  Then, the CPU 6 creates a link relationship by associating each headword in the text headword table 850 with the headword number in the dictionary database 820 (step T2), and ends the headword extraction process. .

  In addition, after this headword extraction processing, when a predetermined user operation such as word book registration is performed on a word that is not registered as a headword in the dictionary database 820, such as a technical term in the explanation information Alternatively, the CPU 6 may store the technical term and the position information of the technical term in the dictionary database 820 in the found word table 850 in the text.

<Information display processing>
As shown in FIG. 8, when content in the flash ROM 8 or the external information storage medium 12a is designated as a display target by operating the menu key 13h or the like (step S1), the CPU 6 determines whether or not text has been designated. If it is determined (step S2) and it is determined that it is not designated (step S2; No), the process proceeds to another process.

It is determined whether or not to be performed (step S4), and when it is determined that the operation is not performed (step S4; No), the process proceeds to another process. When the cursor key 13e or the like is operated in the process of step S3, the CPU 6 switches the text display portion.

  On the other hand, when it is determined in step S4 that the additional search key 13m has been operated (step S4; Yes), the CPU 6 detects the language of the display text based on the information in the text language table 84 (step S5). ), A display screen of the display 10 is divided to provide a text display area 101 (see FIG. 9 and the like) and a search information display area 102 (see FIG. 9 and the like), and a search character string input box 103 (see FIG. 9). 9 (a) is displayed in the search information display area 102 (step S6).

  Next, when a character is input via the character key 13c, the CPU 6 extracts a search word corresponding to the search character string made up of each character from the search word table 850 in the text, and searches the search word storage area. 71, and a list is displayed on the display 10 for each dictionary database 820 (step S7). At this time, every time a character is input, the CPU 6 causes the display 10 to display a list of headwords corresponding to the search character string made up of each character.

  Next, when any dictionary database 820 and a headword are designated by a user operation (step S8), the CPU 6 refers to the headword table 850 in the text to designate a designated view from the designated dictionary database 820. The word explanation information is read out and previewed in a different area from the headword list (step S9).

  Next, when the dictionary database 820 and the headword determination operation are performed by the user operation (step S10), the CPU 6 displays the text in the text display area 101 and the explanation information of the headword in the search information display area 102, respectively. After the display (step S11), it is determined whether or not the return key 13g is operated (step S12).

  If the CPU 6 determines that the return key 13g has been operated (step S12; Yes), the process proceeds to step S3. If it is determined that the return key 13g has not been operated (step S12; No), the information display process is performed. finish.
