Description
Technical field
The present invention relates to character computer input field, be specifically related to a kind of system and method that recovers deleted characters.
Background technology
The computer user will be input to computer with Chinese character, needs to use input in Chinese software.At present, input in Chinese software can be divided into keyboard input and non-keyboard input, and what comparative maturity and use were the widest is the keyboard input.Input in Chinese software is a tool software that operates on the computer operating system, is used for the coding of keyboard input or the media data of other non-keyboard input are converted to the Chinese character input.
(1) keyboard input in Chinese software
Keyboard input in Chinese software is to utilize keyboard, imports the method for Chinese character according to certain coding rule.
English alphabet one has 26, and they are corresponding with 26 letters on the keyboard, so for English what Input Software that do not exist, direct inputting English letter gets final product.And the number of words of Chinese character has several ten thousand, they are deleted relation with keyboard without any quilt, for to Chinese character inputting, we must encode to Chinese character, and with these the coding with keyboard on binding be, just can make us import the coding of certain Chinese character by keyboard, be Chinese character according to code conversion then.
At present, the scheme of encode Chinese characters for computer has had hundreds of, wherein operation on computers just has tens kinds, as a kind of pictograph, Chinese character is to come co expression by the sound of word, shape, justice, the coding method of Chinese character input all is to adopt sound, shape, adopted and specific key are interrelated basically, makes up the input of finishing Chinese character according to different Chinese character again.
(2) non-keyboard input in Chinese software
Non-keyboard input in Chinese software comprises handwriting input software, phonetic entry software, OCR Input Software etc.
Handwriting input software is the hand-written Chinese identification Input Software under a kind of pen type environment, the identical Chinese custom of word that writes with a pen, as long as write by usual custom on handwriting pad, computer just can show its identification.Handwriting input software needs supporting hardware handwriting pad, writes the typing Chinese character with pen (can be the hard-tipped pen of any kind) on supporting handwriting pad, and is not only convenient, fast, and character error rate is also lower.Also can write word in the appointed area with mouse, utilize hand-written software to be converted to Chinese character then, just mouse action requires very skilled.
Phonetic entry software is by the microphone sound import, uses a kind of software that converts literal to then.Though use easily, character error rate is still than higher, particularly some unbred professional term and rarely used words.Phonitic entry method requires computer to be equipped with to carry out normal recording at hardware aspect, and has debugged microphone, carries out words input facing to microphone with mandarin pronunciation.If the mandarin accent is nonstandard, the voice training program that provides with it is provided, carry out the training of a period of time, allow software be familiar with this accent, can realize the literal input by speech too.
The OCR Input Software is also referred to as optical character recognition, and it requires that the manuscript of input is converted into figure by scanner and could discern.Therefore, scanner is necessary, and the printing quality of original copy is high more, and the accuracy rate of identification is just high more, and the general preferably literal of block letter is such as books, magazine etc.If the paper of original copy is thinner, then might when scanning, also throw by figure, the literal of back side of paper, disturb last recognition effect.
Along with intelligent the improving constantly of input method, increasing input in Chinese software can both provide intelligent word (being also referred to as whole sentence generates) and phrase input function.Intelligent word is also referred to as the dynamic group speech or whole sentence generates, and to the phrase that does not have in the dictionary, input method can be searched relevant word and speech, helps the importer to form required candidate's phrase.Import whole phrase or sentence by input in Chinese software and can significantly reduce extra making speech and select the speech operation, improve typing speed.
Yet, the encoded influence of reasonable change of repeated code and Chinese of character input method of today, in intelligent word and phrase input, be not at every turn can both the needed result of the right-on user of presenting, the therefore literal in quick correction group speech of needs or the sentence.In makeover process, in order to correct certain literal, literal that may other are correct is deletion earlier, after corrigendum, more correct literal is re-entered then, and not only the literal input efficiency is low for such character input method, and loaded down with trivial details consuming time.
Below in conjunction with an input method of Chinese character above-mentioned shortcoming is described, for example: the user needs input " will take into account its numeral and optical characteristics ".The user by result shown in Figure 1 as can be known, can find not obtain fully the desirable result of user in a succession of coding of input back (following example figure all adopts Chinese phonetic alphabet coding).For " he " is revised as " it ", certain customers are got used to earlier again it being returned modification behind the screen on first candidate word.Backspace key (Backspace) can be got used to using by certain customers, " his numeral and optical characteristics " behind the last screen all deleted, and then screen in " its numeral and optical characteristics " input.In this example, when Chinese character is revised, can cause some repetitive works as can be seen, thereby make Chinese character input efficiency low, loaded down with trivial details consuming time.

In one embodiment, delete key comprises backspace key.Catching delete instruction can pass through the touch potential that IMM-IME (Inputmethod manager-Input method editor, input method manager-Input Method Editor) catches backspace and obtain.In one embodiment, obtain user's number of times, and judge the number of deletion literal, thereby determine that being deleted the quilt of its corresponding characters of literal in record cell 30 deletes the position according to the number of times that obtains by backspace by input method manager-IMM-IME.
The system of the recovery deleted characters that Fig. 2 embodiment of the present invention is proposed below in conjunction with an input method of Chinese character describes.
For example the pinyin string that is input in the input frame of user is " yao ' jian ' gu ' ta ' de ' shu ' zi ' he ' guang ' xue ' te ' xing ", and the Chinese character that generates at the candidate word list box is " will take into account his numeral and optical characteristics ".Record cell 30 is preserved the pinyin string of input frame input and the Chinese character that the candidate word list box generates.
In the Chinese character that the candidate word list box generates, an erroneous words " he " occurred, need correct.Delete by the pinyin string of importing in 401 pairs of input frames of the character deletion module in the character deletion detecting unit 40, in one embodiment, character deletion module 401 comprises backspace key (Backspace).In delete procedure, obtain 25 backspace number of times by the input method system framework, and determine to be deleted the position of pinyin string at record cell 30 according to the backspace number of times that obtains, also determined that the quilt of being deleted pinyin string and corresponding Chinese character thereof deletes scope.For example: can determine to be deleted the position of pinyin string " ta ", it is deleted the 9th character of inverse of calculating to " yao " from 30 store characters of record cell " yao ' jian ' gu ' ta ' de ' shu ' zi ' he ' guang ' xue ' te ' xing " from " xing ".Can determine to be deleted the position of pinyin string " de ", the 8th pinyin string of inverse that its correspondence is calculated to " yao " from record cell 30 pinyin string that writes down " yao ' jian ' gu ' ta ' de ' shu ' zi ' he ' guang ' xue ' te ' xing " from " xing ".
Undelete among the embodiment one, when user's input Pinyin string " ta ", after " it " chosen screen, character match module 501 was deleted the quilt of pinyin string in record cell 30 according to the quilt that detects to delete the position (was aforesaidly to calculate successively to " yao " from " xing " this moment, " ta " corresponding reciprocal the 9th pinyin string for example), the pinyin string " ta " of judging input whether with record cell 30 in stored with to be deleted the corresponding pinyin string of pinyin string identical, identical by determining relatively later on the 9th pinyin string reciprocal, under identical situation, character and literal recover module 502 in input frame in the output record unit 30 pinyin string after the 9th pinyin string reciprocal and in the candidate word list box 30 storages of output record unit and the 9th pinyin string reciprocal after the Chinese character that is complementary of pinyin string.
In another undeletes embodiment, when user's input Pinyin string " ta ' de ", after " it " chosen screen, this moment, character match module 501 was deleted the correspondence position (be aforesaid inverse 8th pinyin string and 9th pinyin string of from " xing " to " yao " calculating) of pinyin string in record cell 30 according to the quilt of knowing, the pinyin string " ta ' de " of judging input whether with record cell 30 in stored with to be deleted corresponding pinyin string identical, all identical by determining after relatively, character and literal recover module 502 in input frame in the output record unit 30 pinyin string after the 8th pinyin string reciprocal and in the candidate word list box 30 storages of output record unit and the 8th pinyin string reciprocal after the Chinese character that is complementary of pinyin string.
In addition, the present invention in input frame, export described in the store character deleted the character behind the position and output has been stored in the candidate word list box with the described literal that is complementary by character after deleting the position in, the candidate word list box also export with described other candidate characters that are complementary by character after deleting the position for you to choose, particularly occur under the situation of many places mistake in same character corresponding character, when one of them literal of corrigendum, the character and literal in the candidate word list box behind output record unit institute correspondence position, also in other candidate word option, automatically generate and the identical match options of text word more.In one embodiment, the pinyin string that the user is input in the input frame is " yao ' jian ' gu ' ta ' de ' shu ' zi ' he ' ta ' de ' guang ' xue ' te ' xing ", and the Chinese character of screen is " will take into account his numeral and his optical characteristics " on the candidate word list box is selected.The Chinese character that mates with pinyin string that record cell 30 is preserved the pinyin string of input frames input and select screen from the candidate word list box.After " he " is modified to " it ", in addition under the situation that " he " and the corresponding characters " ta " by judging correction and " he " in the Chinese character that will recover and corresponding characters are identical, first option of exporting in the candidate word list box is " numeral and his optical characteristics ", second option exporting in the candidate word list box selected for the user for " numeral and its optical characteristics ", and this is the process of an intelligence coupling.
The system of the recovery deleted characters that Fig. 5 embodiment of the present invention is proposed below in conjunction with an input method of Chinese character describes.
For example the pinyin string that is input in the input frame of user is " yao ' jian ' gu ' ta ' de ' shu ' zi ' he ' guang ' xue ' te ' xing ", and the Chinese character of screen is " will take into account his numeral and optical characteristics " on the candidate word list box is selected.The Chinese character that mates with pinyin string that record cell 30 is preserved the pinyin string of input frames input and select screen from the candidate word list box.
An erroneous words " he " occurred in screen and Chinese character character match in the candidate word list box, selecting, need correct.Delete by the Chinese character that shields in the 601 pairs of selections of literal removing module in the literal deletion detecting unit 60, and detected and deleted the quilt of its corresponding pinyin string of Chinese character in record cell 30 and delete the position by deleting the corresponding character position computing module 602 of literal.
In one embodiment, literal removing module 601 comprises backspace key (Backspace).In delete procedure, obtain 9 backspace number of times by the input method system framework, and determine that according to the backspace number of times that obtains being deleted the quilt of its corresponding pinyin string of Chinese character in record cell 30 deletes the position, also determined that the quilt of being deleted pinyin string and corresponding Chinese character thereof deletes scope.For example, can determine by the position of Chinese character " he ", its correspondence from record cell 30 Chinese character of storing " to take into account his numeral and optical characteristics " from " property " to " will " the 9th Chinese character of inverse of calculating, thereby determine that " he " corresponding pinyin string quilt in record cell 30 deletes the position.Can determine that the quilt of its correspondence deletes the position of pinyin string " ta " (being aforesaid the 9th pinyin string of inverse of calculating successively to " yao " from " xing "), the Chinese character of storing " to take into account his numeral and optical characteristics " from " property " to " will " the 8th Chinese character of inverse of calculating, thereby determine " " corresponding quilt delete pinyin string " " quilt in record cell 30 deletes position (being aforesaid the 8th pinyin string of inverse of calculating successively to " yao " from " xing ").
Undelete among the embodiment one, when user's input Pinyin string " ta ", after " it " chosen screen, character match module 501 is deleted the quilt of its corresponding pinyin string of Chinese character in record cell 30 according to the quilt that detects and is deleted the position at this moment, the pinyin string " ta " of judging input whether with record cell 30 in stored with to be deleted the corresponding pinyin string of pinyin string identical, identical by determining relatively later on the 9th pinyin string reciprocal, under identical situation, by character and literal recover module 502 in input frame in the output record unit 30 pinyin string after the 9th pinyin string reciprocal and in the candidate word list box 30 storages of output record unit and the 9th pinyin string reciprocal after the Chinese character that is complementary of pinyin string.
In another undeletes embodiment, when user's input Pinyin string " ta ' de ", after " it " chosen screen, character match module 501 is deleted the quilt of its corresponding pinyin string of Chinese character in record cell 30 according to the quilt that detects and is deleted position (being aforesaid the 9th pinyin string of inverse and the 8th pinyin string of calculating to " yao " from " xing ") at this moment, the pinyin string " ta ' de " of judging input whether with record cell 30 in the inverse the 9th that write down identical with the 8th pinyin string, if it is all identical, recover module 502 with the 8th pinyin string that pinyin string is later reciprocal and corresponding Chinese character output thereof in the record cell 30 by character and literal, be about to " shu ' zi ' he ' guang ' xue ' te ' xing " and " numeral and optical characteristics " output.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
