Each word in the word list storage area 900 may be further stored in association with the part of speech of the word (see FIGS. 9B and 9C).

[Operation]
Next, the operation of the electronic dictionary 1 will be described with reference to FIGS.

  5 to 7 are flowcharts showing a flow of information display processing in which the CPU 20 reads and executes the information display program 81. 8 and 10 to 14 are diagrams illustrating the display contents of the display unit 40 in the information display process, and FIG. 9 is a diagram for explaining the text analysis process.

  First, as shown in FIG. 5, when the information display process is executed, the CPU 20 performs an operation for causing the user to select a mode such as “text analysis mode”, “text display mode”, and “dictionary search mode”. A menu is displayed on the main display 10 (step S1), and it is determined whether or not the “text analysis mode” is selected (step S2).

  Here, the “text analysis mode” in the present embodiment is a mode for performing processing such as extracting a word from the text data 830 and searching the dictionary database 820. The “text display mode” is a mode for performing processing such as displaying the text data 830 of the text group 83. The “dictionary search mode” is a mode for performing processing such as searching the dictionary database 820 for words input by the user.

  If it is determined in step S2 that the “text analysis mode” has been selected (step S2; Yes), the CPU 20 sets the title of each text data 830 in the text group 83 as shown in FIG. 8B, for example. A list is displayed on the display 10, and selection of text data 830 to be analyzed is received from the user (step S3).

  Next, the CPU 20 performs a text analysis process on the text data 830 selected as the analysis target (step S4).

  Specifically, as shown in FIGS. 6 and 4A, first, the CPU 20 removes symbols such as punctuation marks, parentheses, periods, commas, and syllable symbols from the text data 830 (step A1), and then the text. Words are extracted from the entire data 830 and stored in the word list storage area 900 (step A2). At this time, the CPU 20 detects position information in the text data 830 for each extracted word, and stores it in the word list storage area 900 in association with the word. As a method of extracting words when the text data 830 is in English, for example, a method of separating the text data 830 for each blank character and extracting each divided part as a word can be used. In addition, as a method of extracting words when the text data 830 is Japanese, for example, a method of dividing the text data 830 into words by morphological analysis and converting them into original words can be used. In this embodiment, the number of bytes up to the start position of the word and the number of bytes up to the end position are used as the position information of the word.

  Next, as shown in FIG. 6 and FIG. 4B, the CPU 20 deletes overlapping words from the words in the word list storage area 900 (step A3), and selects words of specific parts of speech. Delete (step A4). In the process of step A4 in the present embodiment, as a specific part of speech, a part of speech that is unlikely to be searched, for example, a be verb or pronoun in English, a definite article, a conjunction, a particle or auxiliary verb in Japanese, etc. It is preset by the user.

  Next, the CPU 20 changes the words in the word list storage area 900 to change words, and additionally stores each change word in the word list storage area 900 (step A5). At this time, as shown in FIGS. 6 and 4C, the CPU 20 stores the same position information as the original word in association with each change word in the word list storage area 900. Here, changing a word means, for example, replacing a verb with an original form, a past tense, a past participle form, a case change form, a countable noun with a singular form, a plural form, or a personal pronoun. Is replaced between the main case, possessive case, objective case, possessive pronoun, and reflexive pronoun, and the adjective is replaced between the original, comparative, and superlative forms. As a method for changing the word in this way, a conventionally known method can be used, such as referring to a table in which a plurality of words are associated with each other and stored. In the present embodiment, only the original word is preset by the user as the type of change word stored in the word list storage area 900.

  Next, as shown in FIGS. 6 and 4D, the CPU 20 stores the words in the word list storage area 900 as search target words in the analysis text word list 840 for the text data 830 to be analyzed. (Step A6), the text analysis process is terminated. At this time, based on the information in the word list storage area 900, the CPU 20 associates position information in the text data 830 with each search target word and stores it in the analysis text word list 840. As a result, a plurality of words are extracted from the text data 830 as search target words and stored together with the position information. Here, in the analysis text word list 840 in the present embodiment, the search target words are stored according to the arrangement order set in advance by the user. Specifically, in the case of English, the search target words are in alphabetical order. In the case of Japanese, it is memorized in the order of Japanese syllabary. Further, the information may be stored in the order of the position information. As shown in FIGS. 9A and 9B, when the text data 830 to be analyzed is Japanese, after the symbols are removed from the text data 830 (step A1), the entire text data 830 is displayed. A word is extracted from and stored in the word list storage area 900 (step A2). Next, as shown in FIG. 9C, overlapping words and words with specific parts of speech are deleted (steps A3 and A4), and original words are stored in the word list storage area 900 (steps). A5). Then, the words in the word list storage area 900 are stored in the analysis text word list 840 in alphabetical order (step A6).

  When the text analysis processing in step S4 is completed, the CPU 20 accepts the keyword search acceptance frame 100 for the words in the analysis target text data 830 selected in step S3, as shown in FIGS. 5 and 8C. Is displayed on the main display 10 (step S5), and a dictionary database 820 having the language of the text data 830 as a search language (entry word language) is set as a selection dictionary (step S6). In the present embodiment, the entry word search acceptance frame 100 is displayed at the top of the main display 10. Further, when there are a plurality of selection dictionary candidates in the process of step S6, the CPU 20 provides a dictionary selection frame 101 at the top of the main display 10 to display a list of candidate dictionary names, and uses the left and right keys of the cursor key 2e. The user can select a selection dictionary.

  When the selected dictionary is set, the CPU 20 causes the main display 10 to display an entry word list display frame 102 and a description information preview display frame 103 in addition to the reception frame 100 and the dictionary selection frame 101 described above. Further, the CPU 20 extracts words corresponding to the headwords in the dictionary database 820 of the selected dictionary from the search target words in the analysis text word list 840, and stores them in the analysis text word list 840 in alphabetical order, A list is displayed in the list display frame 102 in the order of the Japanese syllabary (step S7), and among the headwords (words) displayed in a list, the top headword is highlighted as a selected headword. In the present embodiment, the list display frame 102 is displayed on the lower left side of the main display 10 and the preview display frame 103 is displayed on the lower right side. In FIG. 8C, “G English-Japanese Dictionary” is selected as the selection dictionary. The dictionary database 820a of “G English-Japanese Dictionary” includes “acquiring” among the search target words in the analysis text word list 840. ”,“ Broadest ”,“ focuses ”and the like are not recorded, so the words excluding these are listed in the list display frame 102.

  Next, the CPU 20 retrieves the description information of the selected headword from the dictionary database 820 of the selected dictionary and displays it in the preview display frame 103 (step S8).

  Next, the CPU 20 determines which key in the key group 2 is operated by the user (step S9), and determines that the up / down key of the cursor key 2e is operated (step S9; up / down cursor key). Switches and resets the selected headword in the list display frame 102 in accordance with the direction indicated by the up / down key (step S10), and proceeds to the above-described step S8.

  If it is determined in step S9 that the character key 2c has been operated (step S9; character key), as shown in FIG. 8D, the CPU 20 accepts an input character string input by the character key 2c. While displaying in the frame 100, among the headwords displayed in a list, the headword that matches the input character string is switched and reset as the selected headword (step S11), and the process proceeds to step S8 described above. In step S11 in the present embodiment, the CPU 20 detects a headword that matches the input character string in the forward direction by an incremental search.

  If it is determined in step S9 that the left / right key of the cursor key 2e has been operated (step S9; left / right cursor key), as shown in FIG. 10A, the CPU 20 responds to the direction indicated by the left / right key. Then, the selected dictionary is switched and reset within the dictionary selection frame 101 (step S13), and the process proceeds to step S7 described above. In FIG. 10A, “English-Japanese dictionary” is selected as the selection dictionary. In the dictionary database 820a of this “G English-Japanese dictionary”, among the search target words in the analysis text word list 840, “ Since headwords corresponding to “acquisition”, “based”, “broadest”, “focuses”, and the like are not recorded, words excluding these are displayed in the list display frame 102 as a list.

  If it is determined in step S9 that the translation / decision key 2b has been operated (step S9; translation / decision key), the CPU 20 stores the description information of the selected headword as shown in FIG. 10B. A full screen is displayed on the display 10 (step S12).

  Next, the CPU 20 displays a text display button (not shown) for instructing the display of the text data 830 on the main display 10 or the sub display 11 to determine whether or not the display operation of the text data 830 to be analyzed is performed. If it is determined (step S14) and it is determined that it is not performed (step S14; No), the information display process is terminated.

  On the other hand, if it is determined in step S14 that the display operation of the text data 830 has been performed (step S14; Yes), the CPU 20 explains the selected headword at the top of the main display 10 as shown in FIG. Information is displayed and the text data 830 to be analyzed is displayed at the bottom of the main display 10 (step S15), and the information display process is terminated. More specifically, in this step S15, the CPU 20 includes a range from the start position to the end position of the word corresponding to the selected headword in the text data 830 based on the position information in the analysis text word list 840. The portion is displayed, and the range is identified and displayed in the text data 830 by shading, underlining, color coding, or the like. As a result, a portion including the word corresponding to the selected headword is displayed in the text data 830 to be analyzed, and the word is identified and displayed. In this step S15, when a plurality of words corresponding to the selected headword are included in the text data 830, the CPU 20 selects another part of the text data 830 containing the word by using the cursor key 2e. It is displayed in order by operation.

  If it is determined in step S2 that the “text analysis mode” is not selected (step S2; No), the CPU 20 determines whether or not the “text display mode” is selected as shown in FIG. (Step T1), and if it is determined that it has been selected (Step T1; Yes), the titles of the text data 830 in the text group 83 are displayed in a list on the main display 10 and the user is input via the input unit 30. After receiving the selection of the text data 830 (step T2), the selected text data 830 is displayed on the main display 10 (step T3), and the process proceeds to step T6 described later. In step T3, the CPU 20 displays a selection button (not shown) for screen division search on the main display 10 or the sub display 11. Here, as shown in FIG. 11 and the like which will be described later, the screen division search is performed by providing a text display frame 104 and a search frame 105 in the main display 10 and displaying text data 830 in the text display frame 104. This is a process for searching for a word using a frame 105.

  On the other hand, when it is determined in step T1 that the “text display mode” is not selected (step T1; No), the CPU 20 determines whether or not the “dictionary search mode” is selected (step T4). If it is determined that it is not selected (step T4; No), the process proceeds to another process.

  If it is determined in step T4 that the “dictionary search mode” has been selected (step T4; Yes), the CPU 20 allows the user to select one of the dictionary databases 820 and input a search character string for selection. The headword corresponding to the search character string is searched from the dictionary database 820, and the text data 830 of the explanation information is displayed on the main display 10 (step T5). At this time, the CPU 20 displays a screen split search selection button (not shown) on the main display 10 or the sub display 11. Further, at this time, the CPU 20 stores the dictionary name of the dictionary database 820 as a search source and the searched entry word in association with each other in the history table 85.

  Next, the CPU 20 determines whether or not the screen division search is selected by the user (step T6). If it is determined that the user does not select the screen division search (step T6; No), the CPU 20 proceeds to another process.

  On the other hand, if it is determined in step T6 that the screen division search has been selected (step T6; Yes), the CPU 20 displays the text display frame 104 and the search frame 105 on the main display as shown in FIG. 10 and the text data 830 displayed in step T3 or step T5 is continuously displayed in the text display frame 104.

  Here, in the present embodiment, the text display frame 104 is displayed at the upper part of the main display 10 and the search frame 105 is displayed at the lower part. The headword search at and “collective search” can be selected by the cursor key 2e or the like. Note that “collective search” is a process of performing a search by collectively specifying a plurality of words in the displayed text data 830 as search target words. FIG. 11A shows a state in which “dictionary search mode” is selected in step T4, and explanation information about the headword “take” is displayed on the main display 10, and then screen division search is selected. Show.

  Next, the CPU 20 determines whether or not “collective search” is selected by the user (step T7), and if it is determined that the user does not select (step T7; No), the process proceeds to another process.

  On the other hand, when it is determined in step T7 that “collective search” has been selected (step T7; Yes), the CPU 20 selects whether the search target word is designated by word designation or range designation. The selection button 110 is displayed on the sub display 11. Here, the word designation is a method of individually designating a search target word from the text data 830 being displayed, and the range designation is a method of designating a range in the text data 830 to select a word within the range. It is a method of specifying as a search target word.

  Next, the CPU 20 determines which one of the word designation and the range designation is selected by the user (step T8). When it is determined that the word designation is selected (step T8; word designation), FIG. As shown in b), the upper limit value “n” of the number of words that can be designated as the search target word (n is a natural number; hereinafter, the upper limit number “n”) and the number of designated words “m” (m is This is a natural number, and m = 0 at the time of this step, hereinafter, the designated number “m”) is displayed on the sub-display 11 in the form of “n / m” (step T9). At this time, the CPU 20 also displays a search target word designation end button 111 on the sub-display 11. In the present embodiment, the value of the upper limit number “n” is set to “5” by the user.

  Next, after accepting designation from the user for one word in the text data 830 being displayed (step T10), the CPU 20 displays the designated word and position information of the word in the text data 830. It is stored in the word list storage area 900 (step T11). At this time, the CPU 20 adds one value of the designated number “m” to update the display content of the sub-display 11 and associates the value of the designated number “m” after addition with the stored word. To be stored in the word list storage area 900. Further, at this time, the CPU 20 displays a list of designated words on the sub-display 11. The word designation in step T10 may be performed by a touch operation on the touch panel 31, or may be performed by combining the cursor key 2e and the translation / decision key 2b.

  Next, the CPU 20 determines whether or not the designation end button 111 on the sub-display 11 is operated (step T12). When it is determined that the designation end button 111 is not operated (step T12; No), the designated number “m” is obtained. It is determined whether or not the upper limit number “n” is equal (step T13), and when it is determined that they are not equal (step T13; No), the process proceeds to the above-described step T10. Thus, for example, when the processing of steps T10 to T13 is repeated from the state of FIG. 11B and the words “clutch”, “grab”, and “snatch” on the main display 10 are selected, the main display 10 The sub-display 11 further proceeds to step T10 with the content as shown in FIG. 11C displayed, and the designation of the fourth word is accepted.

  Further, when it is determined in step T12 that the designation end button 111 has been operated (step T12; Yes), or when it is determined in step T13 that the designated number “m” is equal to the upper limit number “n” (step At T13; Yes, the CPU 20 displays a headword list display frame 102 and a description information preview display frame 103 below the text display frame 104 of the main display 10, as shown in FIG. . At this time, the CPU 20 sets a dictionary database 820 that uses the language of the text data 830 being displayed as a search language as a selection dictionary. However, when there are a plurality of selection dictionary candidates, the CPU 20 provides a dictionary selection frame 101 above the list display frame 102 and the preview display frame 103 to display a list of candidate dictionary names, and press the left and right keys of the cursor key 2e. The user is allowed to select a selection dictionary via

  Next, the CPU 20 searches the selected dictionary database 820 for the corresponding headword of the first word in the word list storage area 900 and displays it in the list display frame 102 as a list, and inverts the top headword as the selected headword. The description information of the selected headword is retrieved from the dictionary database 820 of the selected dictionary and displayed in the preview display frame 103 (step T16).

At this time, when the up / down key of the cursor key 2e is operated by the user, the CPU 20 switches and resets the selected headword in the list display frame 102 in accordance with the direction indicated by the up / down key, and displays the preview. When the display content of the frame 103 is updated and the translation / decision key 2b is operated, the explanatory information of the selected headword is displayed at the bottom of the text display frame 104 on the main display 10, as shown in FIG. Display all over. Further, in this step T16, the CPU 20 shades, underlines, or extends the range from the start position to the end position of the word corresponding to the selected headword in the text data 830 based on the position information in the analysis text word list 840. Identification and display by color coding. Thereby, the word corresponding to the selected headword is identified and displayed. Further, at this time, the CPU 20 causes the sub display 11 to display a word switching button 112 in the word list storage area 900.

When deleting a word with a high learning level or a word with a low learning level, only a word with a desired learning level can be left in the word list storage area 900 as a search target word, and therefore, among the words in the text data 830, Explanation information can be searched for words that match the user's level. In addition, when deleting a word stored in the history table 85, a word that the user has searched for before, that is, a word that has a high possibility of knowing the meaning content is the search target word. Therefore, it is possible to efficiently search for explanation information of a word whose meaning is unknown.

  Further, in the processing of step S7, the words in the analysis text word list 840 are described as being displayed in the list display frame 102 in the storage order (alphabetical order, alphabetical order), but are stored in the history table 85. A list may be displayed in ascending order. When displaying a list in the order of the smaller number of stored times, words that are likely to know the meaning content are displayed in the lower order, and words that are likely not to know the meaning content may be displayed in the upper order. Therefore, it is possible to efficiently search for explanation information of words whose meaning is unknown.

  Further, as the position information of the word in the text data 830, the number of bytes up to the start position of the word and the number of bytes up to the end position are used to identify and display the range from the start position to the end position. However, only the start position may be used as the position information of the word, and the space and symbol (comma, period, etc.) immediately after the start position may be identified and displayed. Even in this case, the word can be identified and displayed in the text data 830.
