Description

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

  2. Description of the Related Art Conventionally, electronic devices such as an electronic dictionary having a dictionary function have been provided with a dictionary database that stores each headword and explanation information of the headword in association with each other. The word explanation information is read from the dictionary database, and the headword and explanation information are displayed on the display.

  By the way, in such an electronic device, it is possible to use the contents of the dictionary database as reading material in the train etc. to kill time, but even if the user tries to search for himself, there are quite a few appropriate search terms. It is difficult to select a headword as if flipping through a book dictionary.

  In this regard, as a technique for performing a word test using a dictionary database, a search history is stored, and a technique for giving a question from a headword searched in the past, a technique for randomly giving a question from a dictionary database, a headword Techniques have been proposed in which words are classified into broad fields in advance and questions are given for each field (see, for example, Patent Documents 1 to 3).

JP 2007-219824 A JP-A-9-101737 JP 2006-330186 A

  However, the techniques described in Patent Documents 1 to 3 are techniques for performing a word test, and cannot be simply applied to a technical field that uses dictionary contents as reading materials.

Further, even if the technique of Patent Document 1 can be applied, in this case, only read explanation information is displayed, so that the utility value as a reading material is lowered.
Moreover, even if the technique of Patent Document 2 can be applied, in this case, since the headword is selected completely at random, there is a high probability that a headword that is not of interest at all will be selected. It is also not realistic to repeat the selection until an interesting word is selected.
Furthermore, even if the technique of Patent Document 3 can be applied, in this case, since the user needs to specify the field by himself, the headword of the field in which the user is potentially interested is selected. It is not possible. More specifically, if a user has already searched for a headword, there should be a field of potential interest to the user, but the user himself / herself must be aware of such a field. For example, it is not possible to select a headword by appropriately specifying a field.

  For this reason, the conventional electronic device has a problem that even if it tries to use the contents of the dictionary database as a reading material in order to expand the range of knowledge, it cannot be used as well as a book and is unusable.

[Appearance configuration]
FIG. 1 is a plan view of the electronic dictionary 1.
As shown in this figure, the electronic dictionary 1 includes a main display 10, a sub display 11, and a key group 2.

  The main display 10 and the sub-display 11 are parts for displaying various data such as characters and symbols according to the operation of the key group 2 by the user, and are configured by an LCD (Liquid Crystal Display), an ELD (Electronic Luminescence Display), or the like. ing. The main display 10 and the sub display 11 in the present embodiment are integrally formed with a so-called touch panel 110 (see FIG. 2), and an input operation corresponding to the pressed position is possible by pressing the surface. It has become.

  The key group 2 has various keys that receive operations for operating the electronic dictionary 1 from the user. Specifically, the key group 2 has a translation / decision key 2b, a character key 2c, a dictionary selection key 2d, a cursor key 2e, a shift key 2f, a return key 2g, a history key 2m, and the like. ing.

  The translation / decision key 2b is a key used for executing a search, determining a headword, and the like. The character key 2c is a key used for inputting characters by the user, and includes “A” to “Z” keys in the present embodiment. The dictionary selection key 2d is a key used for selecting a dictionary database 820, which will be described later (see FIG. 2).

  The cursor key 2e is a key used for the reverse display position in the screen, that is, the movement of the cursor position. In the present embodiment, the up / down / left / right directions can be designated. The shift key 2f is a key used when a Japanese word is set as a search target. The return key 2g is a key used when returning to the previously displayed screen. The history key 2m is a key for displaying a list of history entries stored in a history table 84 (see FIG. 2) described later.

[Internal configuration]
Next, the internal structure of the electronic dictionary 1 will be described. FIG. 2 is a block diagram showing an internal configuration of the electronic dictionary 1.

  As shown in this figure, the electronic dictionary 1 includes a display unit 40, an input unit 30, a CPU (Central Processing Unit) 20, a flash ROM (Read Only Memory) 80, and a RAM (Random Access Memory) 90, each of which is a bus. 100 are connected to each other so that data communication is possible.

  The display unit 40 includes the main display 10 and the sub display 11 described above, and displays various types of information on the main display 10 and the sub display 11 based on a display signal input from the CPU 20.

  The input unit 30 includes the key group 2 and the touch panel 110 described above, and outputs a signal corresponding to the pressed key or the position of the touch panel 110 to the CPU 20.

  The CPU 20 executes processing based on a predetermined program in accordance with an input instruction, performs an instruction to each function unit, data transfer, and the like, and comprehensively controls the electronic dictionary 1. Specifically, the CPU 20 reads various programs stored in the flash ROM 80 according to an operation signal or the like input from the input unit 30, and executes processing according to the program. Then, the CPU 20 stores the processing result in the RAM 90 and causes the display unit 40 to output the processing result as appropriate.

  The flash ROM 80 is a memory that stores programs and data for realizing various functions of the electronic dictionary 1. In the present embodiment, the flash ROM 80 stores an information display program 81 according to the present invention, a dictionary database group 82, a related information database 83, a history table 84, a weighting amount table 85, and the like.

  The information display program 81 is a program for causing the CPU 20 to execute a later-described dictionary search process (see FIG. 6) and information display process (see FIG. 8).

  The dictionary database group 82 has a plurality of dictionary databases for English-Japanese dictionaries, Japanese dictionaries, encyclopedias, and the like. In these dictionary databases 820,..., As shown in an example in FIG. 3, for example, explanation information including meaning contents of the headwords is stored in association with a plurality of headwords. .

  The related information database 83 stores each word stored in the dictionary database 820 in association with at least one related information related to the word. More specifically, as shown in FIG. 4, in the related information database 83 in the present embodiment, as related information, a word itself, a genre to which the word belongs, and related words related to the word are stored. ing. In FIG. 4, for simplification of illustration, illustration of words as related information is omitted.

  The history table 84 stores the search history of the dictionary database 820. More specifically, for example, as shown in the upper part of FIG. 9 to be described later, the explanation information of the headword in the dictionary database 820 is read out. When displayed, the headword is stored and stored as a history headword. In the history table 84, the dictionary name of the dictionary database 820 from which the description information is read is stored in association with each history entry word.

  As shown in FIG. 5, the weighting amount table 85 stores weighting amounts for performing statistical calculation in the information display process (see FIG. 8) described later. In this embodiment, the weighting amount table 85 is weighted by a user operation. The amount can be changed.

  The RAM 90 includes a memory area that temporarily holds various programs executed by the CPU 20 and data related to the execution of these programs. In the present embodiment, the RAM 90 includes a selected dictionary storage area 91, an input character storage area 92, first to third statistical result storage areas 93a to 93c, a candidate word storage area 94, a dictionary name storage area 95, and the like. ing.

  Here, the selected dictionary storage area 91 stores the identification information (dictionary name) of the dictionary database 820 selected by the user as the search target of the headword, and the input character storage area 92 The input characters input by the user are stored. In the first to third statistical result storage areas 93a to 93c, the result of statistical calculation is stored in the information display process (see FIG. 8) described later. In the candidate word storage area 94, candidate words for displaying explanation information in an information display process (see FIG. 8) described later are stored. The dictionary name storage area 95 is configured to store dictionary names of the respective dictionary databases 820 in an information display process (see FIG. 8) described later.

[Operation]
(Dictionary search process)
Next, the operation of the dictionary search process among the operations of the electronic dictionary 1 will be described with reference to FIG.

  Here, FIG. 6 is a flowchart showing the flow of dictionary search processing in which the CPU 20 reads and executes the information display program 81.

  As shown in this figure, when the user first selects an arbitrary dictionary database 820 via the input unit 30 and inputs a search character string, the CPU 20 selects the dictionary name of the selected dictionary database 820 as a selected dictionary storage area 91. And the search character string is stored in the input character storage area 92, and the headword corresponding to the search character string is searched from the dictionary database 820 (step S1).

  Next, the CPU 20 displays the searched headword and its explanation information on the main display 10 (step S2), and displays the headword and the dictionary of the dictionary database 820 selected in step S1. The names are associated with each other and stored in the history table 84 (step S3), and the dictionary search process is terminated.

  For example, as shown in FIG. 7, when the user selects the dictionary database 820 of the English-Japanese dictionary and inputs the search character string “east”, the headword “east” corresponding to the search character string “east” is changed to the dictionary database. After the search from 820 (step S1), the searched headword “east” and its explanation information are displayed on the main display 10 (step S2), and the headword “east” and the dictionary are displayed. The dictionary name “English-Japanese dictionary” in the database 820 is associated and stored in the history table 84 (step S3).

(Information display process)
Next, the operation of the information display process among the operations of the electronic dictionary 1 will be described with reference to FIG.

  Here, FIG. 8 is a flowchart showing a flow of information display processing in which the CPU 20 reads and executes the information display program 81.

  As shown in this figure, when the information display process is executed, the CPU 20 first determines whether or not the user performs an “automatic display” instruction operation (step T1), and determines that it is not performed. In the case (step T1; No), the process proceeds to another process. The “reliable display” is a function for automatically detecting headwords in a field of interest to the user and displaying the explanation information.

  If it is determined in this step T1 that the “automatic display” instruction operation has been performed (step T1; Yes), the CPU 20 relates the related information to the word that matches each history entry in the history table 84. Statistical information is extracted by extracting related information associated in the database 83, and the statistical result is stored in the first statistical result storage area 93a (step T2). Here, the statistics of the related information in this step T2 means that the plurality of extracted related information is counted for each related information (for each word, genre, related word).

  For example, when an instruction operation of “remaining display” is performed in a state where the contents shown in the upper part of FIG. 9 are stored in the history table 84 (step T1; Yes), the middle and lower parts of FIG. As described above, related information “map” associated with each word in the history table 84 “map”, “Hong Kong”,... ... Are extracted, counted for each related information, and stored in the first statistical result storage area 93a (step T2).

  Next, the CPU 20 extracts the description information of all history headwords stored in the history table 84 from the corresponding dictionary database 820, that is, the dictionary database 820 associated with the history headword in the history table 84. Then, the extracted explanation information is decomposed into words by performing morphological analysis (step T3).

  For example, as shown in FIG. 7 described above, when the explanation information of the headword “east” is retrieved from the English-Japanese dictionary dictionary database 820 and displayed, the explanation information of the history headword “east” is displayed. Extracted from the dictionary database 820 of the English-Japanese dictionary, the extracted explanation information is morphologically analyzed and broken down into words. More specifically, when the extracted explanation information includes a sentence “Japan is in the east of Asia”, as shown in the first and second rows of FIG. It is broken down into the words “Japan”, “ha”, “Asia”, and so on for morphological analysis.

  Next, the CPU 20 extracts related information associated with the word obtained by the decomposition in the related information database 83, performs statistics, and stores the statistical results in the second statistical result storage area 93b (step T4). Here, the statistics of the related information in step T4 means that the plurality of extracted related information is counted for each related information (for each word, genre, and related words) as in the above-described step T2. means. In the present embodiment, among the words obtained by the decomposition, it is described as extracting information related to words of independent words, more specifically, words of nouns. Information may be extracted.

  For example, when the morphological analysis is performed as shown in the second stage of FIG. 10 and the words “Japan”, “ha”, “Asia”,... Are obtained, the third and fourth stages of FIG. As shown in the tier, related information associated with the noun words “Japan”, “Asia”, “East”,... In the related information database 83 is extracted and counted for each related information. It is stored in the second statistical result storage area 93b (step T3).

  Next, the CPU 20 counts the statistical result (related content of the first statistical result storage area 93a) for the related information of the headword and the statistical result (second statistical value) for the related information of the noun word in the explanation information. The count value of the storage contents of the result storage area 93b) is weighted by the weighting amount of the weighting amount table 85 and added together for each piece of related information (for each word, genre, and related word), and then the entire headword and explanation information The ratio of the count value of each related information is calculated as a statistical result for and stored in the third statistical result storage area 93c (step T5).

  For example, as shown in the upper left and upper right tables of FIG. 11, the count value of the statistical result for the related information of the headword and the count value of the statistical result for the related information of the noun word in the explanation information are obtained. As shown in the middle part of FIG. 11, the related information is weighted so that the statistical result of the related information of the headword: the statistical result of the related information of the noun word in the explanation information = 10: 1. Summing is performed every time, and as shown in the lower part of FIG. 11, the ratio of the count value of each related information is calculated as the overall statistical result.

  Next, the CPU 20 extracts any related information (word, genre, related word) with a probability corresponding to the ratio of the count value of each related information (step T6).

  For example, when the overall statistical result is obtained as shown in the lower part of FIG. 11 above, the related information “map” is extracted with a probability of 26%, and the related information “Asia” with a rate of 19.25%. Is extracted.

  Next, the CPU 20 stores words corresponding to the extracted related information in the related information database 83 in the candidate word storage area 94, and randomly selects any word from the candidate word storage area 94 as a related word. (Step T7).

  Further, the CPU 20 stores the dictionary names of the plurality of dictionary databases 820 stored in the flash ROM 80 in the dictionary name storage area 95, and randomly selects one of the dictionary names as a selected dictionary name from the dictionary name storage area 95. (Step T8).

  Next, the CPU 20 determines whether or not a headword corresponding to the related word is stored in the dictionary database 820 of the selected dictionary name (step T9), and determines that it is stored (step T9; Yes), the headword and its explanation information are retrieved from the dictionary database 820 of the selected dictionary name and displayed on the main display 10 (step T10), and the information display process is terminated.

  On the other hand, when it is determined in step T9 that the headword corresponding to the related word is not stored in the dictionary database 820 of the selected dictionary name (step T9; No), the CPU 20 stores the dictionary name storage area 95. After the selected dictionary name is excluded (step T11), it is determined whether or not the dictionary name is still stored in the dictionary name storage area 95 (step T12). If it is determined that the dictionary name is stored (step T12; Yes) ) Shifts to the above-described step T8.

  If it is determined in step T12 that the dictionary name is not stored in the dictionary name storage area 95 (step T12; No), the CPU 20 excludes the related word from the candidate word storage area 94 (step T13). The process proceeds to step T7 described above.

  According to the above electronic dictionary 1, as shown in FIG. 4 and steps T2, T7 to T10 of FIG. 8, FIG. 9, FIG. 11, etc., the word is associated with at least one related information related to the word. When the related information that is stored in the related information database 83 and is associated with the word that matches the history entry with the description information displayed is extracted according to the user operation, the extracted related information Is extracted as a related word, and the explanation information of the headword corresponding to the related word is read out and displayed. Therefore, when the contents of the dictionary database 820 are used as a reading material, it is a potential for the user. A word of interest is extracted as a related word, and explanation information of a headword corresponding to the related word is displayed. Accordingly, the dictionary database 820 is compared to the conventional case, such as when only read explanation information is displayed, when a headword is selected completely at random, or when the user specifies a field by himself / herself. It is possible to improve the usability when using the contents of as a reading material.

  Further, as shown in steps T2, T6, FIG. 9, FIG. 11 and the like in FIG. 8, statistics are taken for a plurality of related information associated with words matching the history entry word, and each related information Since any of a plurality of related information is extracted with a probability corresponding to the ratio of the statistical results of, after the related information that is of potential interest to the user is statistically extracted, the extracted related information Corresponding words are extracted as related words, and explanation information of head words corresponding to the related words is displayed. Therefore, usability can be further improved when the contents of the dictionary database 820 are used as reading materials.

  Further, as shown in steps T3 to T4 in FIG. 8, FIG. 10, FIG. 11, etc., words included in the explanation information associated with the history entry word are extracted, and the extracted word is Statistics are collected for a plurality of associated information, statistics about the related information of the headword (stored contents of the first statistical result storage area 93a), and statistics about the related information of the noun word in the explanation information. The result (the stored contents of the second statistical result storage area 93b) is weighted at a predetermined ratio and added together for each piece of related information, and any one of a plurality of pieces of related information with a probability corresponding to the ratio of the statistical result after the addition. Therefore, after the relevant information that is of potential interest to the user is statistically extracted from a wide range of fields, the corresponding words for the extracted relevant information are extracted as related words. versus Entry word of explanation information is displayed. Therefore, it is possible to further improve the usability when using the contents of the dictionary database 820 as a reading material.

  Further, as shown in step T4 of FIG. 8, FIG. 10, and the like, the words of the independent words included in the explanation information are extracted, and statistics are taken on a plurality of related information associated with the extracted words. Therefore, compared to the case where words other than independent words are also extracted, after the related information that is of interest to the user is reliably extracted, the corresponding words for the extracted related information are related words. And the explanation information of the headword corresponding to the related word is displayed. Therefore, it is possible to further improve the usability when using the contents of the dictionary database 820 as a reading material.

  The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

  For example, the electronic device according to the present invention has been described as the electronic dictionary 1, but those to which the present invention can be applied are not limited to such products, but are mobile phones, personal computers, PDAs (Personal Digital Assistants), game machines, and the like. It can be applied to all electronic devices. Further, the information display program 81 according to the present invention may be stored in a memory card, CD, or the like that can be attached to and detached from the electronic dictionary 1.

  Further, the statistics of the related information in steps T2 and T4 have been described as counting for each related information (for each word, genre, and related word). It is good also as weighting by a ratio and counting for every relevant information. Specifically, when the related information is extracted as shown in the middle part of FIG. 9 and the weighting amount of word: genre: related word = 3: 2: 1 is set, for example, Since the genre “map”, four genres “words learned in the first year of junior high school”, and one word “map” are extracted, the count value of the related information “map” is 8 (= weighting amount (2)) × number (4)), related information “words learned in the first grade of junior high” has a count value of 4 (= weighting amount (2) × number (2)), and related information “map” has a count value of 3 (= weighting amount) (3) × number (1)).

  In addition, it has been described that the ratio of the count value of the related information is calculated, and any related information is extracted with a probability corresponding to the ratio, but the related information database for a plurality of words matching the history entry word 83, it is good also as extracting the relevant information with the largest count value ratio, that is, extracting the related information with the largest count value ratio. Any related information may be extracted with a probability corresponding to the ratio. Even in these cases, it is possible to further improve the usability when the contents of the dictionary database are used as reading materials.

  The electronic dictionary 1 is provided with one history table 84, and the history table 84 has been described as storing the search history of all dictionary databases 820. However, the same number of history tables 84 as the dictionary database 820 are stored. A search history of the corresponding dictionary database 820 provided in the electronic dictionary 1 may be stored in each history table 84.

Moreover, in the said Example, after determining with the instruction | indication operation of "retail display" having been performed (step T1; Yes), the operation | movement of step T2-step T10 is performed, However, it is not limited to such an order. For example, after the headword and the dictionary name are stored in the history table 84 in association with each other (step S3), until it is determined that an instruction operation of “automatic display” is performed (step T1; Yes) In addition, the operations of Step T2 to Step T9 are performed automatically or manually. Then, if it is determined that an instruction operation of “automatic display” has been performed, the headword corresponding to the word selected in step T7 and its explanation information are searched from the dictionary database 820 of the dictionary name selected in step T8. May be displayed on the main display 10 (step T10), and the information display process may be terminated.
As a result, the operations from step T2 to step T10 can be performed in advance before the “automatic display” instruction operation is performed. Therefore, if the “automatic display” instruction operation is performed, the operation is immediately hidden to the user. It is possible to display the explanation information of the headword corresponding to the word of interest. Therefore, usability can be further improved when the contents of the dictionary database 820 are used as reading materials.
