Description

  The present invention relates to an example sentence search device and an example sentence search processing program suitable for learning a language in which word breaks such as Chinese are difficult to understand.

  Traditionally, various dictionaries and dictionaries such as Japanese language dictionaries, English-Japanese dictionaries, encyclopedias, etc. are converted into electronic data and stored in a storage medium such as a ROM, and various languages and phrases are input as search words based on this data. 2. Description of the Related Art Electronic dictionary devices that search for headwords that match and display corresponding translated words, explanation information, and example sentences are widely used.

  In such an electronic dictionary device, various proposals have been made regarding a function for searching and displaying an example sentence including an input search word.

  For example, as one example sentence search function, there is one that searches and displays an example sentence suitable for a word input as a search word from a dictionary database (see, for example, Patent Document 1).

  In addition, when a plurality of words are input as search words, there is one that searches and displays an example sentence including the input plurality of words in the input order (see, for example, Patent Document 2).

The example sentences searched and displayed by these example sentence search functions are always displayed from the head of the searched example sentence.

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

  FIG. 3 is a flowchart showing the blank insertion process A-1 of the first embodiment in the head aligned state associated with the example sentence search process of the portable device (electronic dictionary) 10.

  FIG. 4 is a diagram showing an example sentence list screen G that is aligned at the head in the example sentence search process of the portable device (electronic dictionary) 10 and the blank insertion process A-1 of the first embodiment.

  FIG. 5 is a flowchart showing the blank insertion process B-1 of the first embodiment in the center aligned state associated with the example sentence search process of the portable device (electronic dictionary) 10.

  FIG. 6 is a diagram showing an example sentence list screen G ′ that is center-aligned in the example sentence search process of the portable device (electronic dictionary) 10 and the blank insertion process B-1 of the first embodiment.

  First, when a search word (Chinese word) is input in response to a user operation on the input unit 16 in, for example, an example sentence search mode setting state in which a Chinese dictionary (Chunichi dictionary) (12e) is specified (step) S1) From among all the example sentences recorded in the Chinese dictionary (12e), each example sentence including a headword that matches the input search word is retrieved and read out to the RAM 13 (step S2). For example, as shown in FIG. 4A, each example sentence is displayed on the display unit 17 as the example sentence list screen G aligned at the head (step S3).

  FIG. 4A shows an example sentence list screen G of each example sentence searched when the Chinese word “treatment” X is input as a search word. In this example sentence list screen G, an arbitrary example sentence among the displayed example sentences can be selected by a reverse cursor C that moves up and down in response to an operation of the cursor key 16b, and corresponds to the selected example sentence. Part of the explanation information read from the Chunichi dictionary (12e) is displayed as an explanation information window W.

  In the example sentence list screen G in which each example sentence is displayed with the head aligned, an instruction of “insert blank” is given in response to a user operation in order to display words in each example sentence in Chinese in an easy-to-read manner. (Step S4 → S6 (YES)), the process proceeds to the blank insertion processing A-1 of the first embodiment with the head alignment in FIG. 3 (Step SA).

  When the blank insertion processing A-1 of the first embodiment with the head alignment is started, the following processing is executed for each searched example sentence.

  That is, the longest matching headword search process based on the Chunichi dictionary (12e) is performed while ignoring the last character sequentially from the example sentence character string to be subjected to the blank insertion processing, and the corresponding headword ( It is determined whether or not there is a word (steps A11 to A13).

  If it is determined that there is a corresponding headword (step A12 (YES)), it is determined whether or not there is a character string following the headword (word) portion searched for matching, that is, the step A12. In step A14, it is determined whether or not there is a ignored character.

  If it is determined that there is a character string that follows the headword (word) portion searched by the first match from the example sentence (step A14 (YES)), a space is added at the end of the headword (word) portion. Is inserted (step A15).

  Then, the processing from Steps A11 to A13 is repeated for the ignored character string remaining after the space is inserted (Step A16 → A11).

  Thereafter, in step A14, if it is determined that there is no character string following the headword (word) portion searched from the example sentence, the blank insertion process A-1 for the example sentence to be processed is performed. Then, the same process A-1 for the next example sentence is executed repeatedly.

  Accordingly, for example, as shown in FIG. 4A, each example sentence searched and displayed as the example sentence list screen G aligned at the beginning is sequentially searched for the longest match from the beginning as shown in FIG. 4B. Spaces P1, P2,..., Pn are inserted and displayed for each headword (word), and the position of each word or search word “treatment” X included in the example sentence and the arrangement order thereof are displayed. Etc. can be easily grasped.

  On the other hand, as shown in FIG. 4 (A), in the display state of the example sentence list screen G with the top alignment searched for example sentences (step S3), the position on each example sentence including the search target word “treatment” X is shown. If it is determined that the “layout” key has been operated by the user for easy viewing (step S4 (YES)), as shown in FIG. 6A, the search target word “treatment” X is edited with the center aligned. The displayed example sentence list screen G ′ is displayed on the display unit 17 (step S5).

  Then, in the example sentence list screen G ′ with the center alignment of the search target word X, an instruction “insert blank” is given in response to a user operation in order to divide words in each Chinese example sentence and display them more easily. Then (step S7 (YES)), the process proceeds to the blank insertion processing B-1 of the first embodiment with the center alignment in FIG. 5 (step SB).

  When the blank insertion process B-1 of the first embodiment with the center alignment is started, the following process is executed for each example sentence centered on the search target word X.

  That is, first, a space is inserted before and after the search target word X included in the example sentence to be subjected to the blank insertion process (step B11). Then, for the character string existing after the search target word X (step B12), the blank insertion processing of the first embodiment with the head alignment shown in FIG. 3 is executed, and from the head of the target character string. A space is sequentially inserted for each entry word (word) searched for the longest match (step BA-1).

  Then, this time, for the character string existing before the search target word X (step B13), a process of sequentially inserting a space for each headword (word) searched for the longest match from the end of the target character string. It is executed (steps B14 to B19).

  That is, the longest matching headword search process based on the Chunichi dictionary (12e) is performed while sequentially ignoring the first character from the character string existing before the search target word X, and the corresponding headword ( It is determined whether or not there is a word (steps B14 to B16).

  If it is determined that there is a corresponding headword (step B15 (YES)), whether or not there is a character string before the headword (word) portion searched for the match, that is, in the step B15 It is determined whether or not there is an ignored character based on the determination of “not applicable” (step B17).

  Then, when it is determined that there is a character string remaining before the headword (word) portion searched with the longest match from the character string before the search target word X with reference to the end thereof (step B17 (YES)). A space is inserted at the beginning of the corresponding headword (word) portion (step B18).

  Then, the processes from Steps B14 to B16 are repeated for the ignored character string remaining before the space is inserted (Step B19 → B14).

  Thereafter, in step B17, when it is determined that there is no character string remaining before the headword (word) portion searched from the character string before the search target word X, the processing for the example sentence to be processed is performed. The blank insertion process B-1 is terminated, and a similar process B-1 for the next example sentence is repeatedly executed.

  Accordingly, for example, as shown in FIG. 6A, each example sentence searched and displayed as the example sentence list screen G ′ centered on the search target word X is searched for as shown in FIG. 6B. Spaces P, P1, P2,..., Pn are inserted and separated for each headword (word) that is sequentially searched for the longest match from the side close to the search target word X in the rear character string and the front character string of the target word X. As a result, the search word “treatment” X included in the example sentence, the position of each word, and the order of arrangement thereof can be grasped more clearly and easily.

  FIG. 7 is a diagram showing a specific example in which a space is inserted between headwords (words) in an example sentence in accordance with the blank insertion process B-1 of the first embodiment with the center alignment in FIG. is there.

  FIG. 8 shows the specific processing steps of the longest matching entry word (word) search process based on the head, which is performed on the character string behind the search target word X in the example sentence in the specific example in FIG. It is a figure explaining.

  FIG. 9 shows a specific process of the longest matching entry word (word) search process based on the end, which is performed on the character string ahead of the search target word X in the example sentence in the specific example in FIG. It is a figure explaining.

  That is, as shown in FIGS. 7A and 7B, after the space P is inserted before and after the search target word “treatment” X included in the searched example sentence “physical education ... treatment nerve weakness ...” (step B11). As shown in FIGS. 8A to 8D, first, the longest matching headword (word) search process based on the head of the backward character string “neural ...” is executed, and the corresponding headword As shown in FIG. 7C, spaces P1, P2, and P3 are inserted (steps B12 and BA-1).

  Subsequently, as shown in FIGS. 9A to 9C, the longest matching headword (word) based on the end of the character string “physical education... ) When the search process is executed and the corresponding headword is searched, spaces P4 and P5 are inserted as shown in FIG. 7C (steps B14 to B19).

  As a result, as shown in FIG. 7D, the headwords (words) included in the example sentence “physical education ... therapeutic nerve weakness ...” to be processed are separated by spaces, and FIG. As shown in FIG. 6, the search target word “treatment” X is reflected and displayed as an example sentence list screen G ′ centered.

  Therefore, according to the example sentence search display function of the first embodiment by the mobile device (electronic dictionary) 10 having the above-described configuration, not only the search target word “treatment” X is displayed as the example sentence list screen G ′ centered, For each example sentence, a headword (word) included in the example sentence is searched based on the position of the search target word “treatment” X, and spaces P, P1,..., Pn are sequentially inserted between the searched words. Even if there is a Chinese example sentence search display that makes it difficult to understand word breaks, not only the position of the search word “treatment” X contained in each example sentence but also the words that follow it And the order of arrangement can be understood very clearly and easily.

  In the blank insertion processing A-1 (see FIG. 3) in the top alignment state and the blank insertion processing B-1 (see FIG. 5) in the center alignment state associated with the example sentence search display processing of the first embodiment, processing is performed. In order to search for and extract headwords (words) contained in the target example sentence, the longest match based on the beginning or end of the character string is sequentially searched, but this will be described in the following second embodiment. As described above, after searching for all headwords (words) up to the first or last character of the character string, for headwords (words) consisting of two or more characters, the degree of importance and the number of characters A configuration may be adopted in which selection is made with priority given to the number, and all headwords (words) are sequentially searched and extracted by repeating this process, and spaces are inserted.

(Second Embodiment)
FIG. 10 is a flowchart showing the blank insertion process A-2 of the second embodiment in the head aligned state associated with the example sentence search process of the portable device (electronic dictionary) 10.

  FIG. 11 is a diagram showing an example sentence list screen G aligned at the top accompanying the example sentence search process of the portable device (electronic dictionary) 10 and the blank insertion process A-2 of the second embodiment.

  FIG. 12 is a flowchart showing the blank insertion process B-2 of the second embodiment in the center-aligned state accompanying the example sentence search process of the portable device (electronic dictionary) 10.

  FIG. 13 is a diagram showing an example sentence list screen G ′ that is center-aligned in the example sentence search process of the portable device (electronic dictionary) 10 and the blank insertion process B-2 of the second embodiment.

  As shown in FIG. 11A, for example, a plurality of example sentences including the input Chinese search word (word) “treatment” X are searched by the processing of steps S1 to S3 in the example sentence search process in FIG. Then, in the example sentence list screen G that is displayed aligned at the top, in order to display words in each Chinese example sentence in an easy-to-read manner, an instruction “insert blank” is given in response to a user operation ( Step S4 → S6 (YES)), the process proceeds to the blank insertion process A-2 of the second embodiment with the head aligned in FIG. 10 (Step SA).

  When the blank insertion process A-2 of the second embodiment with the head alignment is started, the following process is executed for each searched example sentence.

  That is, the longest matching headword search process based on the Chunichi dictionary (12e) is performed while ignoring the last character sequentially from the example sentence character string to be subjected to the blank insertion processing, and the corresponding headword ( It is determined whether or not there is a word (steps A21 to A23).

  Here, if it is determined that there is a corresponding headword (step A22 (YES)), the character string of the headword (word) searched with the longest match is temporarily stored in the RAM 13 (step A24), and the headword It is determined whether or not the search process has been performed until the character string of the target example sentence to be searched becomes one character (step A25).

  If it is determined that one character has not yet been reached (step A25 (NO)), the last character is ignored and the entry word search process based on the Chinese-Japanese dictionary (12e) is performed as described above. (Steps A23, A21).

  Thereafter, in step A25 (YES), that is, the headword search is repeated for the remaining character strings while the character string of the target example sentence is sequentially ignored, and all the headlines that have been searched for matching are repeatedly searched. If it is determined that the word is temporarily stored, it is determined whether or not there is a headword (word) composed of a character string of two or more characters among all the headwords (words) temporarily stored (step) A26).

  Here, if it is determined that there is no headword (word) consisting of a character string of two or more characters among all the headwords (words) temporarily stored, that is, the headword (word) search target character When it is determined that only the first character in the column corresponds to the headword (word) (step A26 (NO)), the character string exists immediately after the first character searched for the headword. (Step A27). If it is determined that a character string exists (step A27 (YES)), a space is inserted at the end of the corresponding one-word entry word (word) portion (step A28).

  Then, the processing from the steps A21 to A23 is repeated for the series of ignored character strings remaining after the space is inserted (step A29 → A21).

  On the other hand, in step A26 (YES), that is, all the headwords (words) searched and temporarily stored while searching for the headword (word) while sequentially ignoring the last character of the search target character string (example sentence). If it is determined that there is an entry word (word) consisting of a character string of two or more characters, the dictionary database 12e stores each entry word consisting of the character string of two or more characters temporarily stored. The importance levels associated with each other are compared (step A210).

  In addition, since the importance level for a single-word entry word (word) is basically set high, here, the importance levels for entry words (words) composed of a character string of two or more characters are compared. .

  Then, it is determined whether or not there are a plurality of character strings (words) having two or more characters having the highest importance (step A211), and one character string (two or more characters having the highest importance is not present, that is, two or more characters having the highest importance) ( If it is determined that a word is found (step A211 (NO)), it is determined whether or not there is a character string following the character string (word) having the highest importance (step A212). If it is determined that a character string exists (step A212 (YES)), a space is inserted at the end of the corresponding character string (word) part with the highest importance (step A213).

  Then, the processing from step A21 to A23 is repeated in the same manner as described above for the series of ignored character strings remaining after the space is inserted (step A29 → A21).

  On the other hand, in step A211, when it is determined that there are a plurality of character strings (words) composed of two or more characters having the highest importance, the plurality of character strings (words) having the highest importance are determined. It is determined whether or not there is a character string following the character string (word) having the largest number of characters (step A214). If it is determined that a character string exists (step A214 (YES)), a space is inserted at the end of the character string (word) portion corresponding to the highest importance and corresponding to the largest number of characters (step A215). .

  Then, the processing from step A21 to A23 is repeated in the same manner as described above for the series of ignored character strings remaining after the space is inserted (step A29 → A21). Thereafter, when it is determined in step A27, A212, or A214 that there is no character string following the headword (word) portion searched from the example sentence under the respective conditions, the processing target The white space insertion process A-2 for the example sentence is terminated, and the same process A-2 for the next example sentence is repeatedly executed.

  As a result, for example, as shown in FIG. 11A, each example sentence searched and displayed as the example sentence list screen G aligned at the top is given importance in order from the beginning as shown in FIG. 11B. Then, spaces P1, P2,..., Pn are inserted and displayed for each headword (word) searched for the longest match, and each word or search word having high importance included in the example sentence is displayed. It becomes possible to easily grasp the position of "treatment" X and the arrangement order thereof.

  Specifically, as shown in FIG. 4B, the head generated through the blank insertion process A-1 of the first embodiment that does not consider the importance of the headword (word) retrieved from the example sentence. In the aligned example list screen G, for example, in the example sentence “physical education…” in the [E] column, a headword (word) “nervation” consisting of four letters following the search word “treatment” X is searched for, and the trailing space P5 11 is inserted, as shown in FIG. 11 (B), the example sentence list screen G with the top alignment generated through the blank insertion process A-2 of the second embodiment in consideration of the importance. Then, it is divided into “nerve” and “weakness” consisting of two letters having higher importance than the “nervous weakness”, and trailing spaces P5 and P6 are inserted respectively.

  On the other hand, as shown in FIG. 11 (A), in the display state of the example sentence list screen G that has been searched for example sentences (step S3), the position on each example sentence that includes the search target word “treatment” X is shown. If it is determined that the “layout” key has been operated by the user for easy viewing (step S4 (YES)), as shown in FIG. 13A, the search target word “treatment” X is edited with the center aligned. The displayed example sentence list screen G ′ is displayed on the display unit 17 (step S5).

  Then, in the example sentence list screen G ′ with the center alignment of the search target word X, an instruction “insert blank” is given in response to a user operation in order to divide words in each Chinese example sentence and display them more easily. Then (step S7 (YES)), the process proceeds to the blank insertion process B-2 of the second embodiment with center alignment in FIG. 12 (step SB).

  When the blank insertion processing B-2 of the second embodiment with center alignment is started, the following processing is executed for each example sentence center-aligned in the search target word X.

  That is, first, a space is inserted before and after the search target word X included in the example sentence to be subjected to the blank insertion process (step B21). Then, for the character string existing after the search target word X (step B22), the blank insertion process of the second embodiment with the head alignment shown in FIG. 10 is executed, and from the head of the target character string A space is sequentially inserted for each headword (word) searched for the longest match in consideration of the importance (step BA-2).

  Then, this time, for the character string existing before the search target word X (step B23), the search is performed sequentially for each headword (word) searched for the longest match by adding importance from the end of the target character string. Processing for inserting a space is executed (steps B24 to B218).

  That is, the longest matching headword search process based on the Chunichi dictionary (12e) is performed while sequentially ignoring the first character from the character string existing before the search target word X, and the corresponding headword ( It is determined whether or not there is a word) (steps B24 to B26).

  If it is determined that there is a corresponding headword (step B25 (YES)), the character string of the headword (word) searched with the longest match is temporarily stored in the RAM 13 (step B27). It is determined whether or not the search process has been performed until the character string of the target example sentence to be searched becomes one character (step B28).

  If it is determined that one character has not been reached yet (step B28 (NO)), the head character search processing based on the Chunichi dictionary (12e) is performed with the leading one character ignored as described above. (Step B26, B24).

  Thereafter, in step B28 (YES), that is, the headword search is repeated for the remaining character strings while the first character of the target example character string is sequentially ignored, and all headlines that have been searched for matching are repeatedly searched. If it is determined that the word is temporarily stored, it is determined whether or not there is a headword (word) composed of a character string of two or more characters among all the headwords (words) temporarily stored (step) B29).

  Here, if it is determined that there is no headword (word) consisting of a character string of two or more characters among all the headwords (words) temporarily stored, that is, the headword (word) search target character If it is determined that only the last character in the string corresponds to the entry word (word) (step B29 (NO)), the character string exists immediately before the one character searched for the entry word at the end. Is determined (step B210). If it is determined that a character string exists (step B210 (YES)), a space is inserted at the head of the corresponding one-word entry word (word) portion (step B211).

  Then, the processes from Step B24 to B26 are repeated for the series of ignored character strings remaining before the space is inserted (Step B212 → B24).

  On the other hand, in step B29 (YES), that is, all headwords (words) searched and temporarily stored while searching for headwords (words) while sequentially ignoring the first character of the character string (example sentence) to be searched. If it is determined that there is an entry word (word) consisting of a character string of two or more characters, the dictionary database 12e stores each entry word consisting of the character string of two or more characters temporarily stored. The associated importance levels are compared (step B213).

  Then, it is determined whether or not there are a plurality of character strings (words) having two or more characters with the highest importance (step B214). If it is determined that a word is found (step B214 (NO)), it is determined whether there is a character string remaining before the character string (word) having the highest importance (step B215). If it is determined that a character string exists (step B215 (YES)), a space is inserted at the head of the character string (word) part of the highest importance level (step B216).

  Then, the processing from Steps B24 to B26 is repeated as described above for the series of ignored character strings remaining before the space is inserted (Step B212 → B24).

  On the other hand, in step B214 (YES), that is, when it is determined that there are a plurality of character strings (words) composed of two or more characters having the highest importance, the plurality of character strings (words) having the highest importance are stored. It is determined whether there is a character string remaining before the character string (word) having the largest number of characters (step B217). If it is determined that a character string exists (step B217 (YES)), a space is inserted at the beginning of the character string (word) portion having the highest importance and corresponding to the largest number of characters (step B218). .

  Then, the processing from Steps B24 to B26 is repeated in the same manner as described above for the series of ignored character strings remaining before the space is inserted (Step B212 → B24). Thereafter, in step B210, B215, or B217, if it is determined that there is no character string remaining before the headword (word) portion retrieved from the example sentence under the respective conditions, the processing target This white space insertion process B-2 for the example sentence is terminated, and the same process B-2 for the next example sentence is repeatedly executed.

  As a result, for example, as shown in FIG. 13A, each example sentence searched and displayed as the example sentence list screen G ′ centered on the search target word X is searched for as shown in FIG. Spaces P, P1, P2,..., For each headword (word) that has been searched for the longest match in order from the side closer to the search target word X in the backward character string and forward character string of the target word X. Pn is inserted and separated to be displayed, so that the search term “treatment” X included in the example sentence and the position of each word having high importance and the arrangement order thereof can be grasped more clearly and easily. Become.

  Specifically, as shown in FIG. 6B, the central word generated through the blank insertion process B-1 of the first embodiment that does not take importance into account for the headword (word) retrieved from the example sentence. In the aligned example list screen G ′, for example, in the example sentence “physical education…” in the [E] column, a headword (word) “nervation” consisting of four letters following the search word “treatment” X is searched for, and a trailing space is found. While P1 is inserted, as shown in FIG. 13 (B), the example sentence list screen center-aligned generated through the blank insertion process B-2 of the second embodiment in consideration of the importance. G ′ is divided into “nerve” and “weakness” consisting of two characters that are more important than the “nervous weakness”, and trailing spaces P1 and P2 are inserted, respectively.

  FIG. 14 shows a specific example in which a space is inserted between each headword (word) taking into account the importance in the example sentence in accordance with the blank insertion processing B-2 of the second embodiment with the center alignment in FIG. It is a figure which shows an example.

  FIG. 15 shows the longest matching entry word (word) search process taking into account the importance performed for the character string behind and the character string ahead of the search target word X in the example sentence in the specific example of FIG. It is a figure explaining the concrete process of no.

  That is, as shown in FIGS. 14A and 14B, after the space P is inserted before and after the search target word “treatment” X included in the searched example sentence “physical education ... treatment nerve weakness ...” (step B21). 15 (A) and 15 (B), the longest matching headword (word) search process is performed, taking into account the importance of the backward character string “neural ...”, based on the beginning of the character string. As shown in FIG. 14 (C), spaces P1, P2, P3, and P4 are inserted each time a corresponding headword is searched with priority given to the importance and the maximum number of characters (step B22, BA-2). .

  Subsequently, as shown in FIG. 15 (C), the longest matching headword (word) taking the importance of the character string “physical education... ) Every time a search process is executed and a corresponding headword is searched with priority given to the highest importance and the most number of characters, spaces P5 and P6 are inserted as shown in FIG. B218).

  As a result, as shown in FIG. 14D, the headwords (words) prioritizing the importance included in the example sentence “physical education ... treatment nerve weakness ...” to be processed are separated by spaces. As shown in FIG. 14E, the search target word “treatment” X is reflected and displayed as an example sentence list screen G ′ centered.

  Therefore, according to the example sentence search display function of the second embodiment by the mobile device (electronic dictionary) 10 having the above-described configuration, not only the search target word “treatment” X is displayed as an example sentence list screen G ′ centered, For each example sentence, a headword (word) included in the example sentence is searched with priority on the basis of the position of the search target word “treatment” X, and spaces P and P1 are sequentially inserted between the searched words. ,..., Pn are inserted and displayed so that even in the case of Chinese example sentence search display in which word separation is difficult to understand, not only the position of the search word “treatment” X included in each example sentence, Each word that follows before and after and the arrangement order thereof can be clearly and easily grasped with very high accuracy.

  In the blank insertion process A-2 (see FIG. 10) in the top alignment state and the blank insertion process B-2 (see FIG. 12) in the center alignment state associated with the example sentence search display process of the second embodiment, After searching for all headwords (words) up to the first character at the beginning or end of the column, for headwords (words) consisting of two or more characters, priority is given to the level of importance and the number of characters. In this configuration, all headwords (words) are sequentially retrieved and extracted by repeating this process, and a space is inserted. However, as described in the third embodiment, the retrieved headlines Instead of word priority, selection and extraction is performed on the basis of the high frequency of use (appearance) of the entry word in all example sentences and the large number of characters. By repeating this process, all entry words (words) are sequentially extracted. Search and extract It may be configured to go to insert the over nest.

(Third embodiment)
FIG. 16 is a flowchart showing the blank insertion process A-3 of the third embodiment in the head aligned state associated with the example sentence search process of the portable device (electronic dictionary) 10.

  The difference between the blank insertion process A-3 of the third embodiment in the head alignment state associated with this example sentence search process and the blank insertion process A-2 (see FIG. 10) of the second embodiment is the second embodiment. In steps A210 to A215 of the form blank insertion processing A-2, the search is performed with priority given to headwords (words) having high importance and a large number of characters, and the space Pn is inserted at the end. In steps A310 to A315 of the form blank insertion processing A-3, there is only a place where a headword (word) having a high use frequency of example sentences and a large number of characters is preferentially searched and extracted, and a space Pn is inserted at the end.

  At this time, the usage frequency in the example sentence of the headword (word) retrieved from the example sentence is read out from the headline example sentence usage frequency table 12 f stored together with the dictionary database 12 e in the ROM 12 and referred to.

  As a result, for example, as shown in FIG. 11A, each example sentence searched and displayed as the example sentence list screen G aligned at the top is used sequentially from the beginning as shown in FIG. 11B. , Pn is inserted and separated for each headword (word) searched for the longest match, and each frequently used word included in the example sentence The position of the search term “treatment” X and the arrangement order thereof can be easily grasped.

  FIG. 17 is a flowchart showing the blank insertion process B-3 of the third embodiment in a center-aligned state accompanying the example sentence search process of the portable device (electronic dictionary) 10.

  The blank insertion process B-3 of the third embodiment in the center aligned state associated with the example sentence search process is different from the blank insertion process B-2 (see FIG. 12) of the second embodiment in the second embodiment. The blank insertion process A-2 (see FIG. 10) by the head alignment of the second embodiment is incorporated in step BA-2 of the blank insertion process B-2 of the embodiment, whereas the blank insertion of the third embodiment is incorporated. In step BA-3 of the process B-3, the blank insertion process A-3 (see FIG. 16) by the head alignment of the third embodiment is incorporated, and the blank insertion process B- of the second embodiment is further incorporated. In steps B213 to B218 of FIG. 2, search and extraction is performed with priority given to headwords (words) having high importance and a large number of characters, and the space Pn is inserted at the head, whereas blank insertion processing B of the third embodiment is performed. -3 steps In 313~A318, located in the place where sentences frequency of use is high and the number of characters is often an entry word search extracted space Pn in the priority the (word) go to top insertion.

  At this time, similarly to the blank insertion processing A-3 of the third embodiment in the head aligned state, the usage frequency in the example sentence of the headword (word) retrieved from the example sentence is stored together with the dictionary database 12e in the ROM 12. Read from the example sentence usage frequency table 12f of the headword to be referred to.

  As a result, for example, as shown in FIG. 13A, each example sentence searched and displayed as the example sentence list screen G ′ centered on the search target word X is searched for as shown in FIG. Spaces P, P1, P2,..., For each headword (word) that has been searched for the longest match in order from the side closer to the search target word X in the backward character string and the forward character string of the target word X. Pn is inserted and separated and displayed so that the search term “treatment” X included in the example sentence and the position and order of each frequently used word can be understood more clearly and easily. Become.

  FIG. 18 shows the longest matching headword (word) in consideration of the frequency of use in the example sentence implemented for the character string behind and the character string ahead of the search target word X in the example sentence in the specific example in FIG. It is a figure explaining the specific process process of a search process.

  That is, as shown in FIGS. 14A and 14B, after the space P is inserted before and after the search target word “treatment” X included in the searched example sentence “physical education ... treatment nerve weakness ...” (step B31). 18 (A) and 18 (B), first, the longest matching headword (word) search process is performed with the use frequency as a reference for the rear character string “neural ...”. As shown in FIG. 14C, spaces P1, P2, P3, and P4 are inserted each time a corresponding headword is searched with priority on the use frequency and the maximum number of characters (steps B32 and BA-3). .

  Next, as shown in FIG. 18 (C), the longest matching headword (word) taking into consideration the frequency of use of the character string “physical education... ) Every time a search process is executed and a corresponding headword is searched with a high usage frequency and the highest number of characters as a priority, spaces P5 and P6 are inserted as shown in FIG. B318).

  As a result, as shown in FIG. 14D, the headwords (words) prioritizing the frequency of use included in the example sentence “physical education ... therapeutic nerve weakness ...” to be processed are separated by spaces. As shown in FIG. 14E, the search target word “treatment” X is reflected and displayed as an example sentence list screen G ′ centered.

  Therefore, according to the example sentence search display function of the third embodiment by the portable device (electronic dictionary) 10 having the above-described configuration, not only the search target word “treatment” X is displayed as an example sentence list screen G ′ centered, For each example sentence, the headwords (words) included in the example sentence are searched based on the position of the search target word “treatment” X with a high use frequency priority, and spaces P and P1 are sequentially inserted between the searched words. ,..., Pn are inserted and displayed so that even in the case of Chinese example sentence search display in which word separation is difficult to understand, not only the position of the search word “treatment” X included in each example sentence, Each word that follows before and after and the arrangement order thereof can be clearly and easily grasped with very high accuracy.

  In the example sentence search and display function of each embodiment, a structure is provided in which a space P is inserted between each entry word (word) included in the searched example sentence to clearly separate and display the boundary between the words. However, the means for separating and displaying the boundaries between the words is not limited to the insertion of the space P, but may be configured to insert some symbols such as a comma [,] to delimit the boundaries.
