Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic dictionary lookup apparatus, and more particularly to an electronic dictionary lookup apparatus which is incorporated in a word processor or the like and serves as one function of "dictionary lookup" in the word processor or the like.

[0002]

2. Description of the Related Art When a document created in a foreign language is displayed on a CRT of a word processor and a word in this document is to be looked up in a dictionary, the operator previously used the meaning of the word by using a dictionary at hand. I was investigating, but this is inefficient,
An electronic dictionary lookup device has been developed because the burden on the operator is heavy. This electronic dictionary lookup device is incorporated in a word processor or the like as described above, and functions as one of its functions.
Just by designating the above characters with a designating device such as a cursor, the meaning of the word containing that character is automatically displayed on the CRT. You can save time and effort as compared to the one that searches the meaning. Therefore, it is a useful device for efficiently reading a document requiring a dictionary lookup.

Conventionally, an electronic dictionary lookup apparatus of this type operates as follows. Explaining the case where the word "institute" in the document shown in FIG. 3 is subjected to dictionary lookup as an example, first, to an arbitrary character in the word "institute" to be dictionary lookup, in this case, "s". The operator moves the cursor and presses a key for instructing a dictionary search. As a result, the device automatically reads the word "institute" containing the character "s" from the specified character "s", and the word "ins" is read.
The Japanese translation "institution" for "titute" is searched, displayed on the CRT, and the dictionary lookup is completed.The displayed state is shown in FIG.

[0004]

However, if the operator is unfamiliar with the language used in the document, or if the document itself is sophisticated, it is necessary to look up many words in the document in a dictionary. is there. However, in the above-described conventional configuration, only one word including the character designated by the operator is looked up in the dictionary. Therefore, when there are many words to be looked up in the dictionary as described above, only the number of words is increased. There was a problem that the dictionary lookup operation had to be performed and the operation became complicated.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide an electronic dictionary lookup apparatus capable of looking up a large number of words with a small number of dictionary lookup operations even if there are many words to be dictionary lookup. .

[0006]

In order to achieve the above object, the present invention provides an operation for operating a cursor for pointing characters in a document of a first language displayed on a display unit and a dictionary lookup for words. Means and a word extracting means for extracting a word in which the character indicated by the cursor is contained when the operating means is operated, and the word in the document when the operating means is operated, At least one word in the forward or backward direction of the words extracted by the extraction means and in the forward or backward direction, or at least one or more words in each of the forward and backward directions. In a dictionary in which the first language and the second language are stored in association with each other using the word string extracting means for extracting the word string and the words extracted by the word extracting means and the word string extracting means as search keys. Locate and a second reading out language dictionary search means corresponding to said word, the second language read the, characterized by comprising a display means for displaying on the display unit.

[0007]

According to the above construction, first, when the operating means is operated in the state where one character is indicated by the cursor, the word extracting means extracts the word including the character, and the word string extracting means In the document, there is at least one direction in the forward direction or backward direction of the words extracted by the word extracting means, and at least one word in the forward direction or backward direction, or in both the front and back directions. At least one or more of each word is extracted, the dictionary search means searches the dictionary using the words extracted by the word extraction means and the word string extraction means as a search key, and a second word corresponding to the word is searched. The language is read and the display means displays the second
The language of is displayed on the display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the electronic dictionary lookup apparatus of the present invention will be described below with reference to the drawings. This electronic dictionary lookup device is incorporated in a document creation device typified by a word processor, and its configuration is shown in FIG. This electronic dictionary lookup device comprises an input unit 101, a computer main body 102, an external storage unit 103, a buffer 104, and an output unit 105.

The input unit 101 is composed of a mode key for selecting a mode and a regular key used in each mode. The mode key is a dictionary lookup mode key 107 for setting a dictionary lookup mode for dictionary lookup, and a cursor designated word. A word shift mode key 147 for setting a word shift mode for changing to the adjacent word is provided, and the common key is the CRT of the output unit 105.

3, an execution key 114 for inputting characters and numerical values stamped on the CRT 109 to the computer main body 102.

The computer main body 102 has an internal storage unit 11.
5 and the central processing unit 116. The internal storage unit 115 is
English document data 116, cursor position information data 117 on the CRT 109, unnecessary word storage location 142 for storing unnecessary words that do not require dictionary lookup, and for translating and displaying the cursor designated word and the secondary cursor designated word. The program 121 is stored. Central processing unit 11
Reference numeral 6 designates a register 118 indicating the number of words designated by the secondary cursor and a register "HOJ" which assists the register 118.
O "119, a register" SHIFT "120 for storing the changing direction when changing the cursor designated word, and a register" J "indicating whether or not the dictionary lookup processing has already been performed.
SHOBIKI "141 is provided, and the program 121 is read out and executed in accordance with an instruction from the input unit 101.

The external storage unit 103 stores dictionary data 122 in which English words are associated with Japanese, and an irregular change table 12 in which the original forms and irregular forms of irregularly changing English words are associated with each other.
Remember 3 As will be described later in detail, when the program 121 translates an English word, the irregular change table 123 is used when the English word is first prototyped. The buffer 104 stores the cursor designated word, the cursor secondary designated word, and Japanese corresponding to these words in association with each other. The output unit 105 is
As described above, the CRT 109 is provided, and an English document according to the document data 116 stored in the internal storage unit 115, a cursor according to the cursor position information data 117, and an English word stored in the buffer 104. And Japanese are displayed on the CRT 109.

The document data 116 in the internal storage unit 115
Represents the position on the screen of the CRT 109 with the secondary coordinates,
The coordinates and the characters of the document are stored in a corresponding state. 2 shows the document data 116 stored in the internal storage unit 115, and FIG. 3 shows the document data 11 shown in FIG.
6 shows a state in which 6 is displayed on the CRT 109. Figure 2
As shown in FIG. 7, the document data 116 is a table in which the left side is a coordinate field and the right side is an English character storage field, and the coordinates and the English characters accommodated in the same row are associated with each other. That is,
The first row "A" in the English character storage field is the coordinate (0,
0), which is located at the beginning of the screen at the upper left corner on the CRT 109 in FIG. Similarly, the “n” in the third row of the English character storage column is the coordinates (0, 2) of the same row.
It corresponds to, and is arranged with a space in between from the position of "A" on the CRT 109. The position information data 117 of the cursor is indicated by coordinates. FIG. 4 shows an example thereof. According to this coordinate data (1, 18), the cursor is located at the position in the document shown in FIG.

The register 118 is a register "MA".
There is an E ”124 and a register“ USHIRO ”125. The register“ MAE ”124 stores a numerical value that specifies how many words up to the previous word from the cursor specified word are to be looked up in the dictionary. 1
25 is a direction opposite to the register "MAE" 124, and stores a numerical value for designating how many words after the cursor designated word the dictionary is looked up. External storage unit 1
The dictionary data 122 of No. 03 has an English column on the left and a Japanese column on the right, and is stored in each column of the English column. An English word corresponds to the same level of Japanese. FIG. 6 shows an example of the irregular change table 123. It is divided into seven columns, from the left end to the right end, "original form", "past form",
"Past participle", "present participle", "comparative", "superlative", "plural", that is, verbs, adjectives, adverbs, and nouns with the same variants I memorize the variants of the so that they come to the same stage. Therefore,
The original form of a word can be extracted from an arbitrary form of an irregularly changing English word.

The program 121 for translating and displaying the cursor-designated word and the secondary cursor-designated word is an initial value setting program 144, a word extraction program 126, a prototype program 127, a word string extraction program 128,
Word change program 129, word shift program 13
0, a comment display program 143. The initial value setting program 144 stores the number of the secondary cursor designated words in the register “MAE” and the register “USHIRO”, stores the unnecessary word in the unnecessary word storage location 142, and stores the initial value in the register “JISHOBIKI” 141. The numerical value "0" is stored as.

The word extraction program 126 extracts a word including the character from the character designated by the cursor, that is, a word designated by the cursor. The position information data 117 of the cursor in the internal storage unit 115 is read out and the document data 116 is read. This is a program showing a well-known procedure in which a special character located before and after the position information is searched for and found, and a character between the found position information is read out. The special characters here are spaces and?
,! ,:,;,. ,,, etc., which appear at the breaks between words. The prototype program 127 converts the English words used in the document into the irregular change table 123.
Alternatively, it is a program showing a well-known procedure for forming an algorithm. That is, the English words extracted from the document are first searched as the search key in the irregular change table 123, and if there is the same search key in the irregular change table 123, the original form of the same is found. Read out. If not, the ending of the word is "ed", "ing",
It determines which of "er", "est", and "s" it corresponds to, and removes those characters from the ending if any. On the other hand, if those letters are not included in the ending, the word itself is output as the original form.

The word string extraction program 128 extracts several words before and after the cursor-specified word read by the word extraction program 126, that is, a secondary cursor-specified word. The numerical value stored in the "MAE" 124 is read out, then the subsequent word from the cursor designated word is read out by the numerical value stored in the register "USHIRO" 125, and these read word and cursor are designated. The original form of the word is extracted by the original forming program and stored in the buffer 104. The word-by-word recognition follows the known procedure shown by the word extraction program 126.

The word changing program 129 removes unnecessary words from the words extracted by the word string extracting program 128. First, the unnecessary words are read from the unnecessary word storage location 142 of the internal storage unit 115, and then the word string extracting program. Every time 128 extracts a word, it is determined whether or not the extracted word matches the read unnecessary word,
If they match, the word string extraction program 128 discards the word just extracted, changes it to the word next to it, and causes it to be extracted.
The dictionary search program 145 translates each English word stored in the buffer 104 using the dictionary data, and stores these translated Japanese words so as to correspond to the English words.

The word shift program 130 replaces the cursor designated word extracted by the word extraction program 126 with
This is to extract a secondary cursor designated word and Japanese that shifts to the word next to this word and that changes with this shift, that is, the word at the end on the right side in the shift direction in the document and the Japanese for this word. Is omitted from the buffer 104, the word next to the word on the lower side in the shift direction is stored in the buffer 104, and this word is looked up in the dictionary to read out Japanese and this Japanese is stored.

The comment display program 143 displays on the CRT 109 a comment for requesting operator's instruction information for operating each of the above-mentioned programs. The comment display program 143 specifies the number of secondary cursor designated words in the initial value setting, unnecessary words, and cursor designation. Comment the information request such as word change on the CRT. The control operation of the central processing unit 116 will be described below with reference to the following example and flowchart. In this example, a word including the character indicated by the cursor shown in FIG. 3 and three words before and after this word are made to look up in the dictionary, and Japanese corresponding to these words is searched out.
Display these words and Japanese. After that, change the cursor specified word to the next word,
First, it tries to display the next three words and Japanese. The flow charts are shown in FIGS.
8 is a main flowchart of the control operation of the central processing unit 116, FIGS. 8 to 12 show one processing step of the main flowchart shown in FIG. 7, FIG. 8 is a flowchart of initial value setting, and FIG. 9 is a dictionary. FIG. 10 is a flowchart for extracting the secondary cursor designated word in the dictionary lookup flowchart of FIG. 9, FIG. 11 is a flow chart for changing the cursor designated word, and FIG. 12 is a flow chart for changing the cursor designated word in FIG. Are shown respectively.

First, the dictionary look-up mode key 107 of the input unit 101 is operated to set the mode to the dictionary look-up mode instead of the mode for processing a normal word processor (S10). Then, first (see FIG. 8), the comment display program 143 and the initial value setting program 144 are read and executed. On the CRT 109, a comment "Y if initial value setting is to be made, N if not to be input" is displayed, and the operator waits for input (S20). When the operator inputs Y (S21), a comment "number of words before the cursor-specified word?" Is displayed, and the operator waits for input. When a numerical value is input (S22), the input numerical value is stored in the register "MA
Store it in E. In this case, enter the numerical value "3".
Then, this numerical value is stored in the register "MA" of the internal storage.
It is stored in E ″ 124 (S23).
Comment on 9: "Number of words after the cursor-specified word?"
Is shown. When a numerical value is input (S24), the input numerical value is stored in the register "USHIRO" this time (S25). In this case, the numerical value is "3" as in the previous case.
Enter. Then, this value is registered in the register "USH
IRO ”125. Further, the comment“ Y is set if the unnecessary word is set, N is set if not set. If “Y” is input, the unnecessary word is set,
If it is "N", no unnecessary word is set. In this case, since there are no unnecessary words, "N" is input (S26, S27).
Then, "0" indicating that there is no unnecessary word is stored in the unnecessary word storage location 142 of the internal storage unit. This completes the setting of the initial value. The case where "Y" is input will be described later with an example. When the initial value is not set (S21), the register "M
The numerical value "1" is input to AE "and the register" USHIRO "(S31), and" 0 "is stored in the unnecessary word storage location 142 (S32).

When the initial value setting is completed, the dictionary lookup process starts. First, the word extraction program 126 is called and executed. That is, the cursor designated word is extracted (S43). In this case, since the cursor points to the character "s" as shown in FIG. 3, the document is written based on the position information data (1,18) of the cursor in the internal storage unit 115 shown in FIG. Cursor specified word “inst” from data
“Iute” is read (S43).

Next, the word string extracting program 128 is read out and executed in accordance with the procedure for extracting the secondary cursor designated word shown in FIG. 10 (S44). First, the cursor designated word read out earlier is processed into a prototype (S50). It should be noted that this prototype processing is executed by calling the prototype program 127, and is a publicly known one that prototypes English words by the irregular change table 123 or an algorithm as described above. In this case, the cursor designated word is "i
Since it is "nstate", the word is used as a search key to search the irregular change table 123 shown in Fig. 6. There is no same thing as this word "institute". Next, "ed" and the ending of the word If there is no match, the "ed" part is removed from the word.If there is no match, the same operation as "ed" is performed for "ing", and if there is no match, the "er" is continued. "Es
t "and then" s "and the above process is repeated. If there is no match, this word itself is shown as the original form. In this case, the above characters" ing "," ed "," e "are used.
"r", "est", and "s" are not included in the endings, so "i"
nstateute "is output as it is.

Next, a place for storing the cursor designated word (hereinafter referred to as "0" designated place) is set (S5).
1) The cursor designated word is stored in this place (S5)
2). Next, the storage location of the word to be looked up in the dictionary is set in the buffer 104 (S53). First, register "MAE" 1
24 is read out, and a place is provided in the buffer 104 so that it is located at a position before the "0" designated place by the numerical value thereof (hereinafter, the "0" designated place is immediately adjacent to the "1" designated place, "2" designated place, next to it "3" designated place ...
Called. ) ”And register“ USHIRO ”1
25 is read out, and after the "0" designated place, just as in the above, as many places as the numerical value are provided in the buffer 104 (hereinafter, "-" is immediately adjacent to the "0" designated place.
1 "designated place, its neighbor is called" -2 "designated place, its neighbor is called" -3 "designated place, ...) Furthermore, Japanese for those English words is stored below each designated place. Set the location, in this case register "MAE" 12
4 and the register "USHIRO" are both 3, and the cursor designation word is "institute", the buffer 104 stores the location setting and the word as shown in FIG.

Next, a word is stored in each designated place, and FIG.
The processing of the word string extraction program indicated by 0 is completed. That is, first, the register "MAE" 124 is read again, and this numerical value is stored in the register "HOJO" (S
54). Next, if this register "HOJO" is read and the numerical value is not 0 (S55), 1 is subtracted from this numerical value and the result is stored in the register "HOJO" (S56), and the word immediately before the cursor designated word is written in the document data. Is read from (S57). Then, the prototype program 127 is read again, and the prototype of the English word just read is extracted (S5
8) The data is stored in the "1" designated location of the buffer 104 (S59). Next, the register "HOJO" is read again, and if this numerical value is not 0 (S53), 1 is subtracted from this numerical value and stored in the register "HOJO" in the same manner as described above. Then, the word immediately before the cursor designated word is read from the document data, the original form of this English word is extracted in the same manner as described above, and stored in the "2" designated location of the buffer 104. Thereafter, the above processing is performed until the value of the register "HOJO" becomes 0 (S56 to S59).

Next, instead of the register "MAE" 124, the register "USHIRO" 125 is read, and this numerical value is stored in the register "HOJO" (S60). After that, words are extracted in the same manner as above, but different from the above. , "-1" designated place, "-2" designated place, "-3" designated place, and so on, in the order of extracting the extracted words (S62 to S65). FIG. 14 shows the storage state of the buffer 104 after the above processing is completed.

Next, returning to FIG. 9, the dictionary search program 1
45 is read out and executed (S45). First, buffer 1
The English word in the "0" designated place in 04 is read, the dictionary data 122 is searched using this as a search key, and the Japanese for that English word is read out and stored in the lower storage location of the "0" designated place. Next, the English word at the "1" designated location is read, the dictionary data 122 is searched using this as a search key in the same manner as described above, and the Japanese word for that English word is read out and stored in the lower storage location of the "1" designated location. Remember. After that, the same processing as described above is performed for each designated location. In the present case, the English word "ins" in the designated location "0" shown in FIG.
"title" is read out, and this is used as a search key.
The dictionary data 122 shown in is searched to read the Japanese language "institution", and this is stored in the lower storage location of the "0" designated location. Next, the English word in the designated place of "1" is "the".
Then, the Japanese "that" is stored in the lower storage location of the designated location "1". After that, the same processing as described above is performed for each designated location, and the result is as shown in FIG.

Next, the contents of the buffer 104 are displayed on the CRT 109 of the output unit 105 (S47), "1" is stored in the register "JISHOBIKI" 141 (S47), and the dictionary lookup processing is terminated. In the display, the storage locations of the English word and the Japanese language at the left end of the buffer 104 shown in FIG. 15 are associated with the first row of the CRT 109, and the second storage location from the left edge is associated with the second row from the top. Similarly, after that, the third storage location from the left end,
On the CRT 109, it corresponds to the third row from the top. The contents of the buffer 104 shown in FIG. 15 are displayed on the CRT 109 in FIG.

Next, returning to FIG. 7, the comment display program 143 displays a comment on the CRT 109 such that a comment "dictionary lookup mode key when ending dictionary lookup and cursor designation word change, and word shift mode when cursor designation word change is performed. Key ”. When the word shift mode key 147 is operated (S14, S15), the cursor designated word changing process is performed according to the processing procedure shown in FIGS. 11 and 12 (S16). First, as shown in FIG. 11, the register “JISHOBIKI” 141 is read, and if the numerical value is “1”, the cursor designation word change processing is performed according to the procedure shown in FIG. 12 (S65, S6).
6) If "0", "Cannot change word designated by cursor" is displayed on the CRT 109 (S65, S67). The reason why the word designated by the cursor cannot be changed when the register “JISHOBIKI” 141 is “0” is
The dictionary lookup process for the cursor specified word has not been performed yet,
This is because the cursor designated word and the secondary cursor designated word are not fixed. In this case, word shift mode key 1
Operate 47. Then, word shift program 1
Read out 30 and execute according to the procedure shown in FIG.
First, the forward key 112 or the backward key 113 and the execute key 114 are operated to specify whether the word is before or after the cursor-specified word (S70). In this case, the forward direction key 112 is operated to specify the word "The" before the cursor specifying word "institution". When the direction key is operated, the position information data 117 of the cursor in the internal storage unit is changed to the position information data of the character included in the changed word. In this case, the position information of the cursor in the internal storage unit changes to the coordinates (1, 26) indicating the letter "T" of the word "The". Further, the operated direction key is the front direction key 11
If it is 2, the register “SIFT” 140 is “0”. If the backward key 113, the register “SIFT” 140 is “1”.
Memorize The position of the cursor on the CRT 109 is also changed by changing the position information data of the cursor.

Next, if the numerical value stored in the register "SIFT" 140 is "0", the leftmost English word and Japanese among the respective English words and Japanese stored in the buffer 104 are erased. At the same time, the other English words and Japanese are re-stored in the designated locations on the left side (S72).
Further, the cursor position information data and the register "USH"
IRO ”125 is read, document data is searched based on these information, and the word preceding the word including the character currently indicated by the cursor by the numerical value of the register“ USHIRO ”125 is read (S73), After that, the prototyping program 127 is read out and executed, the prototypical form of the read word is extracted (S74), and as described above, the leftmost English words and English words other than Japanese and Japanese are placed on the left adjacent designated location. As a result of re-storing, the read word is stored in the designated position at the right end of the buffer 104 in which nothing is stored (S75), and the dictionary is looked up using this word as a search key, The Japanese word for this word is read out and stored in the lower part of the designated place at the right end just stored (S81) On the other hand, if it is "1", it is stored in the buffer 104. Of the respective English words, the rightmost English word and Japanese are erased from the memory, and the other English words and Japanese are stored again in the right adjacent place (S77) Next, the register "USHIRO" 125 Register "MA
After changing to E ″ 124, the same processing as described above is performed, the English word is stored in the leftmost position of the buffer 104, and the Japanese language is stored in the lower row (S78 to S81), and the cursor designated word changing processing is ended.

In this case, the register "SIFT" 140 is "1", the cursor position information is (1, 26), and the register "USHIRO" 125 is "3". The designated word becomes "The", and the third word after this becomes "460", and this "460" is stored in the rightmost position of the buffer 104. FIG. 17 shows the storage state of the buffer 104 at this time. The reason why the lower part of "460" is blank is that there is no Japanese for "460" as a result of looking up the dictionary. The processing in S14 and S15 described above is performed again. That is, on the CRT 109, a "dictionary lookup mode key when ending the dictionary lookup and changing the cursor designated word, a word shift mode key when changing the cursor designated word" is displayed, waiting for the input, and the word shift mode key is displayed. When 147 is operated, the above processing (S70 to S81) is repeated, and when the dictionary lookup mode key is operated, the dictionary lookup processing is completed. Although the unnecessary words are not set in the above example, the case where the unnecessary words are set to “the” and “by” in the above embodiment will be described below as an example. When the unnecessary words "the" and "by" are input by the alphabet key and the execution key after the numerical value of the cursor designated word is input, the unnecessary words "the" (hereinafter referred to as the first unnecessary word) and "by". "(Hereinafter, referred to as a second unnecessary word.)
Is stored in the internal storage unit. Then, when the word changing program 129 shown in FIG. 10 is read and executed, the word string extracting program 128 is different from the above-described example.
The unnecessary word is read before the secondary cursor word is extracted by. Then, every time a word is extracted and prototyped by the word string extraction program 128 (S26, 61),
It is determined whether or not the original form of this word is the same as the unnecessary word, and if it is the same, the extracted word is changed to the adjacent word. In this case, first, the Unnecessary word "the" and the second unnecessary word "by" are read out. Then, the word string extraction program 128 extracts and standardizes the words. This prototyped word is "the", and this word and the first unnecessary word "t"
This is the same as "he". This word (hereinafter referred to as an unnecessary matching word) is not stored in the buffer 104, and the next word is extracted and prototyped. The next word is "kept".
The original form is “keep” according to the irregular change table 123 of FIG. 6, and this word is not the same as the first unnecessary word and the second unnecessary word. It is stored in a designated place (“1” designated place) that should be initially stored. After that, the above processing is repeated for each designated location in the buffer 104. In FIG. 18, in the document shown in FIG.
The storage state of the buffer 104 in the above case in which the unnecessary words are set to “the” and “by” is shown as “e”.

Although the case where English is taken as a document and it is read in Japanese has been shown, the present invention is not limited to this. For example, the document may be German, French, or Spanish. , Russian, etc., the language to be read and the various languages mentioned above are also possible, and even if the words are not separated by special characters such as spaces, such as Japanese, By dividing the language into words, Japanese documents can be treated like English above.
