Description

  The present invention relates to a dictionary search device suitable for learning a language in which words such as Chinese are difficult to understand, and a control program therefor.

  Traditionally, various dictionaries and dictionaries such as English-Japanese dictionaries, English-English dictionaries, English thesauruses, Japanese-English dictionaries, and Japanese dictionaries are converted into electronic data and stored in storage media such as ROM, and various languages and phrases are searched based on this data. 2. Description of the Related Art A dictionary search apparatus that is input as a character string and that reads and displays explanatory information such as translated words and meaning contents of searched headwords (words, etc.) is widely used.

  In recent years, in such a dictionary search device, a desired headword is searched and the text of the headword and explanation information is displayed, or various texts inputted from the outside using the Internet or a memory card are displayed. After the display, a jump search function is provided in which an arbitrary character string in the text is directly specified, and a dictionary search is further performed for the specified character string.

  Conventionally, in this jump search function, when a character or character string for jump search is specified from the displayed text, the character string up to the subsequent delimiter position including the specified character (character string) at the beginning is the target. All matching headwords are retrieved from the dictionary database and displayed.

  For this reason, the character (character string) specified as the jump search target must itself be the word or the first character (character string) of the word, but in the case of text such as Chinese, there is no change between the words. Since there are no kanji enumerations, especially beginners do not know the word breaks, and it is not possible to perform a jump search by specifying the appropriate first character well.

In addition, an electronic dictionary that can perform a jump search using both Japanese and Chinese dictionary databases for kanji text has been considered (for example, see Patent Document 1).

  Next, a dictionary search function by the mobile device (electronic dictionary) 10 having the above-described configuration will be described.

  FIG. 2 is a flowchart showing a dictionary search process (part 1) by the portable device (electronic dictionary) 10.

  FIG. 3 is a flowchart showing dictionary search processing (part 2) by the portable device (electronic dictionary) 10.

  FIG. 4 is a diagram showing an operation display state (part 1) associated with a jump search using a daytime dictionary in dictionary search processing by the portable device (electronic dictionary) 10.

  FIG. 5 is a diagram showing an operation display state (part 2) associated with the jump search by the daytime dictionary in the dictionary search process by the portable device (electronic dictionary) 10.

  For example, when performing a Chinese dictionary search, if the “Chinese” key of the input unit 16 is operated to select Chinese dictionary data [daytime] 12b (step S1), this Chinese dictionary (12b) A search word input screen (not shown) based on the above is displayed on the display unit 17 (step S2).

  On this search word input screen, for example, when Japanese “flowering” is input as a search word (step S3), this search word “blossoming” is stored in the search character data memory 12e and the search word The text data of the Chinese headword translation (explanatory information) corresponding to “flowering” is read from the Chinese dictionary data [daytime] 12b (step S4), as shown in FIG. The explanation information display screen G1 is displayed on the display unit 17 (step S5).

  In the explanation information display screen G1 based on this [daytime] dictionary, in order to perform a jump search from the text of the explanation information, the “jump” key is operated to switch to the jump search mode (step S6). When the reverse cursor K on the explanation information text is controlled to move according to the operation of the cursor key (steps S7 → S8), the text where the reverse cursor K is moved is stored in the fixed word memory 12f (completed) It is determined whether or not it is a word (step S9).

  For example, since there is no confirmed word on the explanatory information text on the explanatory information display screen G1 shown in FIG. 4A, one character corresponding to the moving position of the reverse cursor K is displayed on the text in a reverse-identified manner. (Step S9 → S10).

  Then, on the explanatory information text in FIG. 4A, when the reverse cursor K is moved and displayed as “cold” and designated (step S10), the “translation / decision” key is operated (step S11). ), A series of character strings “March-style spring cold use ...” (see FIG. 4B) from the front delimiter including the designated character “Kan” to the rear delimiter is cut out (step S12). .

  Then, in the series of character strings “March-style spring kan ...” including the designated character “CHAN”, first the headword for the character string after “CHAN”, and the character string before “CHAN” The headwords that match backwards for, and for all the combination strings that are increased or decreased the character string before and after "Cold", up to the word that matches "Cold" one character, all in order from the headword of the longest match character string Search is performed (step S13).

  At this time, there is already a character string that matches the confirmed word (12f) with respect to the series of character strings “March-style spring and cold use ...” (see FIG. 4B) that is the search target extracted in step S12. (Step S14), and if it is determined that there is no fixed word (12f) (step S14 (No)), the headword searched in step S13 is shown in FIG. As shown in C), “[A] [Chunkan]”, which is a backward match with the designated character “Cold”, in order from the longest matching entry, and “[B] [Cold”, which is the designated character “Cold” itself. ] ”As a list in the search headword list window W (step S15).

  On the other hand, if it is determined that there is already a character string that matches the confirmed word (12f) for the series of character strings that are the search target extracted in step S12 (step S14 (Yes)), the step The headwords searched in S13 are first displayed in the search headword list window W in order from the longest matching headword, starting with the headword that is the determined word (step S16). .

  Then, in the display state of the search word list window W (see FIG. 4C), the search word desired by the user is designated and displayed by the reverse cursor K in accordance with the operation of the cursor key (step S17). → S18), the explanation information of the translation of the headword indicated by the cursor is read from the Chinese dictionary data memory [daytime] 12b and displayed in parallel as the preview screen P1 (step S19).

  In the parallel display state of the search headword list window W and the designated headword explanation information preview screen P1 (see FIG. 4C), the designated headword “Chunkan” is determined. Accordingly, when the “translation / decision” key is operated (step S20), the designated headword “Chunkan” is a confirmed word as a confirmed word in the series of character strings “March-style Chunkan ...” to be searched. It is stored and registered in the memory 12f (step S21). At this time, the character position of the new confirmed word in the series of character strings “March-like spring cold use ...” registered in the confirmed word memory 12f partially overlaps with the character position of the original confirmed word already registered. If the position is misaligned, the original confirmed word is corrected according to the new confirmed word (step S21).

  Then, the explanation information text of the translation of the designated headword “Chunkan” is read from the Chinese dictionary data memory [daytime] 12b, and the display unit 17 displays the explanation information display screen G1 of the headword “Chunkan”. (Step S22).

  When the “return” key is operated on the explanation information display screen G1 of the headword “Chunkan” searched for jump in this way (step S23), the text display screen of the jump source, in this case, in accordance with steps S1 to S5 above The explanation information display screen G1 corresponding to the input search word “flowering” displayed in text (see FIG. 4A) is re-displayed as shown in FIG. 5A (step S24), and the explanation information is displayed. The reverse cursor K on the display screen G1 is moved and displayed at the character position of the headword “Chunkan”, which is the confirmed word registered this time (step S25).

  Then, the character string of the headword “Shunkan”, which is the confirmed word on the explanatory information display screen G1 displayed in the text, identifies the confirmed word in the text as shown in FIG. Is displayed surrounded by a frame with a symbol (in this case "A") added (step S26).

  Then, the explanatory information text of the translation of the headword “Shunkan” of the fixed word is read from the Chinese dictionary data memory [daytime] 12b, and as shown in FIG. It is displayed (step S27).

  Thereafter, the jump search / determined word registration process in steps S7 to S22 is repeated on the basis of the explanation information display screen G1 corresponding to the input search word “flowering” which is the same text display screen as the jump search source. When the explanation information display screen G1 corresponding to the input search word “flowering” of the jump search source is displayed in response to the operation of the “return” key each time (steps S23 and S24), each time the jump search is repeated, Since a new confirmed word that has been searched / designated / registered is added, for example, as shown in FIGS. 5B and 5C, the confirmed word is added to each new confirmed word (in this case, “use”, “flower”,...). A symbol for identification (in this case, “B”, “C”...) Is displayed surrounded by a frame (steps S25 to S27).

  In this case, by moving the reverse cursor K with the cursor, each confirmed word [A “Spring”] [B “use”] [C “flower”]... Is specified, and explanation information of the translation of the designated confirmed word Although the text can be displayed as the preview screen P2 (steps S7 to S9 → S26, S27), the symbols [A], [B], [C],. By doing so, the explanatory information text of the translation of the fixed word designated by the symbol can be displayed as the preview screen P2 very easily.

  In the embodiment described with reference to FIG. 4 and FIG. 5, the description has been given of the case where the text display screen of the jump search source is the explanation information display screen G1 corresponding to the input search word. A case where a jump search is performed from the text display screen G2 will be described with reference to FIG.

  FIG. 6 is a diagram showing an operation display state associated with a jump search from a text display screen based on a Chunichi dictionary in a dictionary search process by the portable device (electronic dictionary) 10.

  For example, when document data stored as an example in the Chinese dictionary data [Chunichi] 12b is designated (step S28), the text of the designated document is read (step S29), and FIG. ), The text display screen G2 is displayed on the display unit 17 (step S5).

  In the text display screen G2 shown in FIG. 6A, in order to perform a jump search from the text, after the “jump” key is operated to switch to the jump search mode (step S6), the cursor key operation is performed. If the reversing cursor K on the text is controlled to move according to (steps S7 → S8), it is determined that the text where the reversing cursor K is moved is not a confirmed word stored in the confirmed word memory 12f. (Step S9 (No)), one character corresponding to the moving position of the reverse cursor K is reversely identified and displayed (Step S10).

  Then, on the Chinese text display screen G2 in FIG. 6A, the "translation / decision" key is operated with the reverse cursor K moved to "one" and designated (step S10). And (step S11), a series of character strings “other righte ... the first god of heaven ...” are cut out from the preceding delimiter including the designated character “1” to the rear delimiter (step S11). S12).

  Then, in the series of character strings “other remedies… the first god of heaven character…” including the designated character “one”, the first matching word for the character string after “one”, The longest matching character string, including the headword that matches backward for the character string before "1", and the headword that matches "one" and one character for all combination character strings that are increased or decreased by the character string before and after "one" Are searched in order from the headword (step S13).

  At this time, it is determined that there is no definite word (12f) for the series of character strings “other righteous ... first letter of heaven ...” that is the search target cut out in step S12 (step S14 ( No)), the headword searched in the above step S13 is matched by including the designated character “one” in order from the longest matching headword as shown in FIG. 6B. ] [First letter of heaven] ”,“ [B] [first] ”that matches the designated character“ one ”backward,“ [C] [one] ”that matches the designated character“ one ”, A list is displayed in the search word list window W as “[D] [one]”, which is the designated character “one” itself (step S15).

  Then, in the display state of the search headword list window W (see FIG. 6B), the user-desired search headword (for example, “Tenji No. 1”) is highlighted in accordance with the operation of the cursor key. K is designated and displayed (steps S17 → S18), and the explanation information of the translation of the headword indicated by the cursor is read from the Chinese dictionary data memory [Chunichi] 12b and displayed in parallel as the preview screen P1. (Step S19).

  In the parallel display state (see FIG. 6B) of the search headword list window W and the preview screen P1 of the designated headword explanation information, the designated headword “Aji No. 1” is displayed. When the “translation / decision” key is operated to confirm “” (step S20), the designated headword “Tenji No. 1” is a series of character strings “other right ... It is stored and registered in the confirmed word memory 12f as a confirmed word in the first character of character ... "(step S21).

  Then, the explanation information text of the translation of the designated headword “Tenji No.1” is read from the Chinese dictionary data memory [Chunichi] 12b, and the explanation of the headword “Tenji No.1” is read. The information display screen G1 is displayed on the display unit 17 (step S22).

  When the “return” key is operated on the explanation information display screen G1 of the headword “Tenji No. 1” searched for jump in this way (step S23), the text display screen of the jump source, in this case, the above step The Chinese text display screen G2 displayed in accordance with S28, S29, and S5 (see FIG. 6A) is redisplayed as shown in FIG. 6C (step S24), and the text display screen is displayed. The reverse cursor K on G2 is moved to the character position of the headword “Tenji No. 1”, which is the confirmed word registered this time, and is displayed (step S25).

  Then, the character string of the headword “Tenji No. 1”, which is the confirmed word on the text display screen G2, is used to identify the confirmed word in the text as shown in FIG. It is surrounded and displayed by a frame to which a symbol (in this case “A”) is added (step S26).

  Then, the explanatory information text of the translation of the headword “Tenji No. 1” of the fixed word is read from the Chinese dictionary data memory [Chunichi] 12b and previewed as shown in FIG. The screen P2 is displayed in parallel (step S27).

  Next, there is a confirmed word in the text to be searched for jump, and the text display screen is displayed surrounded by a frame with each symbol for each confirmed word, and the character range of the confirmed word is The operation when the change is corrected will be described with reference to FIGS.

  FIG. 7 is a diagram showing an operation display state (part 1) associated with a jump search from the explanatory information display screen G1 having a confirmed word by a Chinese-Japanese dictionary in a dictionary search process by the portable device (electronic dictionary) 10.

  FIG. 8 is a diagram showing an operation display state (part 2) associated with a jump search from the explanation information display screen G1 having a confirmed word by a Chinese-Japanese dictionary in a dictionary search process by the portable device (electronic dictionary) 10.

  That is, in the explanation information display screen G1 based on the Chinese dictionary data [Chunichi] 12b as shown in FIG. 7A, the fixed word [2 characters already surrounded by the frame of the symbol A by the above-described jump search [ In the state where two handles of the fixed word [finger] surrounded by the frame of the symbol “B” and the symbol B are successively registered and displayed, the cursor K is used to move the reverse cursor K to the fixed word [the handle of the symbol A]. ] Is read, the explanation information of the translation corresponding to the confirmed word [grip] is read, and a preview screen P2 as shown in FIG. When moved to the position of the confirmed word [finger ...], the explanation information of the translation corresponding to the confirmed word [finger ...] is read and the preview screen P2 as shown in FIG. (Steps S7 to S9 → S2 , S27).

  Then, as shown in FIG. 7B, in the state where the confirmed word [finger ...] in the frame of the symbol B on the explanatory information display screen G1 is designated by the reverse cursor K, the “translation / decision” key is operated. When further jump search is instructed (step S11), a series of character strings "grip fingers ..." including the designated characters (determined words) "finger ..." are cut out (step S12), and the designated characters are extracted. (Fixed word) The headword of the longest matching character string including two characters "finger ..." and the headword of the longest matching character string including any one character are searched in order (step S13).

  At this time, since it is determined that the character string “finger ...” that matches the confirmed word (12f) already exists in the series of character strings “grip fingers ...” that are search targets cut out in step S12 ( Step S14 (Yes)), as shown in FIG. 8A, the headword searched in the step S13 is the longest match with the headword “finger ...” that is the confirmed word first. Are sequentially displayed in the search word list window W as [hand ...] [finger ...] [finger] ... [... (head)] (step S16).

  At this time, in the display state of the search headword list window W (see FIG. 8A), the search headword [hands ...] desired by the user is designated and displayed by the reverse cursor K according to the operation of the cursor key. Then (steps S17 → S18), the explanation information of the translation of the headword [finger ...] indicated by the cursor is read from the Chinese dictionary data memory [daytime] 12b and displayed in parallel as the preview screen P1. (Step S19).

  Then, in the parallel display state (see FIG. 8A) of the search headword list window W and the preview screen P1 for the designated headword explanation information, the confirmed word [finger ...] When the “translation / decision” key is operated to confirm the currently designated headword [finger ...] having a different character range (step S20), the designated headword [finger ...] is determined as the confirmed word. It is stored and registered in the confirmed word memory 12f (step S21). At this time, the character position of the new confirmed word [finger ...] registered in the confirmed word memory 12f is misaligned partially overlapping with the character position of the original registered word [finger ...] already registered. Therefore, the original confirmed word [finger ...] is corrected according to the new confirmed word [finger ...] (step S21).

  Thus, when the “return” key is operated on the explanation information display screen G1 (step S22) of the headword [finger ...] after the jump search again, the jump source text display screen, In this case, the explanation information display screen G1 of the Chinese dictionary [Chunichi] shown in FIG. 7A is redisplayed as shown in FIG. 8B (step S24), and the explanation information is displayed. The reverse cursor K on the display screen G1 is moved to and displayed at the character position of the headword “finger ...”, which is the confirmed word changed and registered this time (step S25).

  At this time, if the reverse cursor K is moved to the position of the confirmed word [bunch] in the frame of the symbol A by the cursor operation, the explanation information of the translation corresponding to the confirmed word [bunch] is read, and FIG. When the preview screen P2 as shown in FIG. 4 is simultaneously displayed and moved to the position of the confirmed word [finger ...] in the frame of the symbol B, the explanation information of the translation corresponding to the confirmed word [finger ...] is read out. Thus, a preview screen P2 as shown in FIG. 8B2 is simultaneously displayed (steps S7 to S9 → S26, S27).

  In this way, when a confirmed word already exists in the text to be jump searched, the character range of the confirmed word can be changed and corrected in accordance with another jump search.

  Therefore, according to the dictionary search function of the mobile device (electronic dictionary) 10 having the above-described configuration, any text display state such as the explanation information display screen G1 corresponding to the search headword or the externally input text display screen G2 can be used. When jump search is instructed by specifying a character with the cursor, a series of character strings including this specified character are cut out, and the headword that matches the specified character at the beginning, the headword that matches back, and the middle match As a headword that matches the headword and the designated character itself, each headword including the designated character is searched from the dictionary data 12b and 12c in the longest match order and displayed as a list, and this list is displayed. By specifying the desired headword of each headword with the cursor and registering it as a confirmed word, the explanation information of the translation of this designated headword (determined word) is displayed. Chinese text consisting enumeration of Chinese characters do not know even the word separator, even if that target, it is possible to dictionary pull finds the appropriate words from meaningless string to.

  Further, according to the dictionary search function by the mobile device (electronic dictionary) 10 having the above-described configuration, a word including a designated character is confirmed and registered by jump search from the text display screen as a search target, and the explanation information of the translation is obtained. After the display, when the text display screen of the jump search source is displayed again in response to the operation of the “return” key, the words that are confirmed and registered by the jump search are surrounded by a frame with a symbol for identification display. Therefore, it becomes possible to appropriately confirm the character position of the confirmed word on the Chinese text screen composed of the enumeration of Chinese characters.

  Further, according to the dictionary search function of the mobile device (electronic dictionary) 10 having the above configuration, when the character (character string) designated by the cursor on the text display screen is the confirmed and registered word, Since the explanation information of the translation of the headword, which is a word, is read from the dictionary data memories 12b and 12c and displayed as the preview screen P2, for example, on the Chinese text display screen, the characters in the continuous kanji character string are displayed. Repeat the specified jump search process to register and register words that exist as headwords in the character string. Then, move the cursor over the kanji character string on the text display screen to handle each confirmed word. The explanation information can be switched and displayed in a preview so that the meaning of the sentence formed by the kanji character string can be easily understood.

  Further, according to the dictionary search function of the mobile device (electronic dictionary) 10 having the above-described configuration, a search word (word) including a character (character string) designated on the text display screen is searched from the dictionary data memories 12b and 12c. When there is a headword (word) that has been confirmed and registered when the list is displayed, the list can be displayed with the confirmed word at the head position.

  Furthermore, according to the dictionary search function of the mobile device (electronic dictionary) 10 having the above-described configuration, the headword (word) already registered and displayed as a confirmed word by the jump search is further designated by specifying the confirmed word. By performing a search, if a headword having a character string range different from that of the original confirmed word is searched and registered as a new confirmed word, the original confirmed word is corrected and registered as a new confirmed word. Therefore, when the text display screen of the jump search source is displayed again after this, the frame with a symbol is changed from the original character string range to the new fixed word character string range for identification. It will be displayed.
