Embodiment

The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here Limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure Completely it is communicated to those skilled in the art.

One of core concept of the present invention is：Aided filter strokes sequence recognition rule is pre-set, is being inputted in user Input button corresponding with aided filter strokes sequence can be clicked in method keyboard at an arbitrary position, then press to input by user In key sequence, Direct Recognition aided filter strokes sequence input by user, so as to be carried out to the corresponding words of phonetic below Filter, reduces the range of choice of follow-up character/word, so as to improve input efficiency.

Embodiment one

With reference to Fig. 1, it illustrates a kind of flow diagram of character input method of the present invention, can specifically include：

Step 110, under the Two bors d's oeuveres input pattern of input method, receiving keystroke sequence input by user；

In embodiments of the present invention, the extra recognition rule for keystroke sequence can be pre-set, that is, is used to identify auxiliary The recognition rule of filtering strokes sequence is helped, such as, button " hspdz " is corresponding " Philosophy folding " respectively, such as h-" one ", s- " Shu ", p-" Pie ", d-" Dian ", z-" second ", then set the button being of little use in guiding button, such as the input method such as #, when defeated When entering in method some or certain several buttons in input guiding button+foregoing hspdz, then the hspdz is accordingly identified For stroke.

It is i.e. preferable, further include：

Sub-step 101, setting different key correspond to each stroke of the writing system, obtain pair of button and stroke respectively It should be related to.

I.e. such as foregoing h-" one ", s-" Shu ", p-" Pie ", d-" Dian ", z-" second ".

Certainly, further include default aided filter strokes sequence and correspond to the pinyin string for filtering which position.

User then can click on respective keys by rule as needed under above-mentioned rule in click keys.

Step 120, judge whether the keystroke sequence includes aided filter strokes sequence；If the keystroke sequence includes Aided filter strokes sequence, then enter step 130；

The keystroke sequence so inputted for user in double-spelling Chinese character input method, can identify therein auxiliary according to above-mentioned rule Help filtering strokes sequence.For not aided filter strokes sequence then, will be according to the normal recognition logic of double-spelling Chinese character input method, will Recognition by pressing keys is phonetic.

Sub-step 121, judges whether there is filtering boot symbol in the keystroke sequence；

For example using # as guide key, 1 (can certainly be n) button for representing next to input is aided filter Stroke.And may also dictate that it is that stroke filtering is carried out to a Chinese phonetic alphabet string before #.Ta#pmen is so inputted with user Exemplified by.First and second recognition by pressing keys are Chinese phonetic alphabet string ta, and the 3rd is #, then has filtering boot symbol.According to foregoing rule Then, 1 button behind is needed to be identified as stroke.

Sub-step 122, if there is filtering boot symbol in the keystroke sequence, is filtered described behind boot symbol at least One recognition by pressing keys is aided filter strokes sequence；

For example by the p behind #, it is identified as " Pie " according to the correspondence of p and stroke.

I.e. wherein, include when identifying aided filter stroke：

Sub-step 1221, is aided filter stroke by corresponding recognition by pressing keys according to the button and the correspondence of stroke.

If the button behind the # is not the foregoing button for having correspondence with stroke, according to the normal of input method Recognition logic is identified, for example input by user is ta#omen, then is identified as ta#pmen, i.e., not auxiliary in the keystroke sequence Filtering strokes sequence is helped, certainly for this kind of situation, the character of defined quantity behind # can not also be handled.

Sub-step 123, judges whether there is filtering boot symbol first symbol in the keystroke sequence；

The embodiment of the present invention can also pass through Macintosh or two guide keys (filtering boot symbol first symbol and filtering boot symbols End mark) input multidigit aided filter stroke.

For example " () " corresponding filtering boot symbol first symbol and filtering boot symbol end mark respectively, character among bracket can be with It is identified as aided filter strokes sequence.And may also dictate that it is that stroke filtering is carried out to a pinyin string before " () ".Such as User inputs ta (ps) men, and first and second recognition by pressing keys are Chinese phonetic alphabet string ta, the 3rd for (, then have filtering guiding First symbol.According to aforementioned rule, n button behind is needed to be identified as stroke, until recognizing).

Sub-step 124, if there is filtering guiding first symbol in the keystroke sequence, sequentially starts the filtering guiding The recognition by pressing keys of symbol below is aided filter stroke, until recognizing filtering guiding end mark, obtains aided filter strokes sequence.

Ps can be so identified as to aided filter strokes sequence " Pie Shu ".

If the button in () is not the foregoing button for having correspondence with stroke, according to the positive general knowledge of input method Other logic is identified, for example input by user is ta (po) men, then is identified as ta (po) men, or user inputs ta (ab) Men, then be identified as ta (ab) men, i.e., do not have aided filter strokes sequence in the keystroke sequence, certainly for this kind of situation, () and character therein can not be handled.

Sub-step 125, judges whether functional button is combined with the input of character keys in the keystroke sequence；

In embodiments of the present invention, function button can also be set, receive the character that user inputs together with function button Button, for example, ctrl+ " p ", wherein p could alternatively be arbitrarily with the relevant character of stroke.And also could dictate that it is to ctrl+p A pinyin string before carries out stroke filtering.For example user inputs ta ctrl+pctrl+s men, wherein the ta first inputted, Ctrl and p is to input at the same time, and ctrl and s is to input at the same time afterwards, then the men inputted.

Sub-step 126, judges that functional button is combined with the input of character keys in the keystroke sequence, then will be described defeated The character keys entered in combination are identified as aided filter strokes sequence.

For previous example, then first and second recognition by pressing keys for the Chinese phonetic alphabet string ta, ctrl and p are while defeated Enter, identification p correspondences " Pie ", ctrl and s are to input at the same time, and identification s corresponds to " Shu ", then obtains aided filter strokes sequence " Pie Shu ".

If the character keys inputted at the same time with function button certainly are not the foregoing buttons for having correspondence with stroke, It can fail to see and be clipped in the pinyin string of input method.Such as ta ctrl+octrl+s men, then pinyin string ta and men, and auxiliary are identified Stroke s is filtered, since o does not correspond to stroke, then nonrecognition, is also not input in pinyin string.

If the keystroke sequence does not include aided filter strokes sequence, it is by the recognition by pressing keys in the keystroke sequence Pinyin string；

Step 130, for the keystroke sequence before or after the aided filter strokes sequence corresponding to pinyin string, Matched with the aided filter strokes sequence with the word corresponding to the pinyin string and/or the first strokes sequence of word；

, can be according to advance regulation, to aided filter strokes sequence after identification obtains aided filter strokes sequence Before or after keystroke sequence corresponding to pinyin string, with corresponding to the aided filter strokes sequence and the pinyin string Word and/or the first strokes sequence of word matched.

Such as foregoing regulation, the pinyin string before auxiliary stroke filtration sequence is filtered, for ta#pmen, then with " Pie " the corresponding words of ta are filtered, can obtain " they "；For ta (ps) men, then with " Pie Shu " carry out the corresponding words of ta Filtering, can obtain " they "；For ta ctrl+pctrl+s men, then with " Pie Shu " and the corresponding words of ta are filtered, can be with Obtain " they ".

It is of course also possible to provide to filter the pinyin string before auxiliary stroke filtration sequence, filtering principle is similar.

Step 140, according to auxiliary strokes sequence and the matching result of the first strokes sequence, it is corresponding each to adjust each pinyin string The display location of word and/or word.

Input such as " tamen " for normal Two bors d's oeuveres, can obtain word " they ", " they ", " they ", " pyller " etc. Candidate, then for being filtered mentioned by aided filter strokes sequence to the phonetic before it, then can obtain " they " Deng less, more accurately candidate, then using these more accurately candidate word and/or word as upper screen candidate item initially.

The embodiment of the present invention is due in double-spelling Chinese character input method, for the letter of a-z input by user, by the knowledge of double-spelling Chinese character input method Not, it is that corresponding pinyin string can be split as by the regulation of the initial and the final, and each pinyin string can correspond to different words, is spelled The combination of sound string can also correspond to different words, and the embodiment of the present invention can be clicked at an arbitrary position in user in entering method keyboard Input button corresponding with aided filter strokes sequence, then in keystroke sequence input by user, Direct Recognition user inputs Aided filter strokes sequence, so as to be filtered to the corresponding words of pinyin string below, reduce the selection model of follow-up character/word Enclose, so as to improve input efficiency.

In embodiments of the present invention, can be with for the first strokes sequence of the corresponding each word of each each pinyin string and/or word At least the first stroke of each word is extracted, by least the first stroke is combined as the first strokes sequence described in each word.For example take the of each word One composition the first stroke screening sequence, or take the first two strokes of each word to form the first stroke screening sequence etc..It is so described Aided filter strokes sequence is formed with by least first stroke of the corresponding each word of each each pinyin string and/or each word of word The first strokes sequence matched.

Sub-step 541, by the aided filter strokes sequence and the complete pen by the corresponding each word of each pinyin string and/or word The first strokes sequence for drawing sequence composition is matched；

The complete stroke of the corresponding each word of each pinyin string and/or each word of word can be extracted in embodiments of the present invention Come, form the first strokes sequence, such as " Asia ", the complete strokes sequence of " Asia " is " a Shu Shu Pie Dian mono- ", the complete stroke in " continent " Sequence is " mono- Dian Pie Dian Shu Dian Shu " of Dian Dian, then the first strokes sequence of composition is " a mono- Dian Dian of Shu Shu Pie Dian, mono- Dian Pie Dian Shu Dian Shu ", the aided filter Strokes sequence can be matched with first strokes sequence.

And/or sub-step 542, by the aided filter strokes sequence with by the corresponding each word of each pinyin string and/or word First strokes sequence of first stroke composition matches.

The complete stroke of the corresponding each word of each pinyin string and/or each word of word can be extracted in embodiments of the present invention Coming, form the first strokes sequence, such as foregoing " Asia ", the first stroke of " Asia " is " one ", and the first stroke in " continent " is " Dian ", The first strokes sequence so formed is " Dian ", and the aided filter strokes sequence can be matched with first strokes sequence.

Sub-step 543, for each initial candidate item, obtains the first stroke sequence of each initial candidate item from dictionary Row.

In embodiments of the present invention, the stroke of each word can be preserved in dictionary in advance, which can be when mounted with visitor Family end is installed under the specified path of system.

In the embodiment of the present invention, receive user input aided filter strokes sequence process before, among or afterwards, The first strokes sequence of the corresponding each word of each each pinyin string and/or word can be extracted from dictionary.Certainly such as the institute of embodiment one State, the first stroke that at least first stroke is formed of each word of the corresponding each word of each each pinyin string and/or word can be extracted Draw sequence.

Sub-step 544, when the first strokes sequence of the aided filter strokes sequence and the initial candidate item is incomplete During matching, the first of the strokes sequence input by user and the initial candidate item is judged using the error correcting model based on stroke The matched probability of strokes sequence；

In practical applications, user input aided filter strokes sequence when, may input error, such as input " fast " word When, by five-stroke input method " one, Shu, Pie, Dian, second " exemplified by, correct stroke order should be " one Pie Dian " of Dian Dian Shu second, and for erect the heart Other input then easily malfunctions, such as " Shu Dian Dian ", then the input of this kind mistake then can by based on the error correcting model of stroke to its into Row judges, judges the first stroke sequences match of strokes sequence input by user each word corresponding with each pinyin string and/or word Probability.

Sub-step 545, when the matched probability is more than threshold value, then judge the aided filter strokes sequence with it is described In first stroke sequences match of initial candidate item.

When judging that the strokes sequence input by user is corresponding with each pinyin string by the error correcting model based on stroke The probability of the first stroke sequences match of each word and/or word when being more than certain threshold value, then it is believed that the aided filter pen In the first stroke sequences match for drawing sequence each word corresponding with each pinyin string and/or word；It is on the contrary, then it is assumed that not match On.

Preferably, further include：

Sub-step 546, it is described based on stroke using the binary or n-tuple relation of words in phrase and/or sentence, structure Error correcting model；

Binary crelation, the probability occurred in succession for representing two elements, i.e. P (B | A), under conditions of representing that A occurs, B The probability of appearance.N-tuple relation is derived by binary crelation.

In embodiments of the present invention, can be straight according to phrase or sentence according to advance statistics phrase and the stroke of words The direct binary of word or n-tuple relation connect determines the probability that stroke occurs.For example happy strokes sequence is " one Pie Dian of Dian Dian Shu second Pie second Shu Pie Dian ", obtain that " the corresponding happy probability of one Pie Dian Pie second Shu Pie Dian " of Dian Shu Dian second is 90%, and " one Pie Dian Pie second Shu Pie Dian " of Shu Dian Dian second are right by statistics It is 79% to answer happy probability, and so on, so as to build the error correcting model based on stroke.In this way, for not matching each spelling The stroke of the corresponding each word of sound string and/or word screens sequence, can judge that stroke is sieved according to the above-mentioned error correcting model based on stroke The matching probability of sequence each word corresponding with each pinyin string and/or word is selected, if greater than threshold value, for example more than 60%, then may be used Think that the corresponding each word of each pinyin string and/or word are matched.

And/or sub-step 547, using the binary or n-tuple relation between the stroke for forming each word, build the base In the error correcting model of stroke.

For example " one Pie Dian " of Dian Dian Shu second are that statistics can obtain strokes sequence, and " one Pie Dian " of Dian Shu Dian second correspond to " fast " word to the stroke of " fast " word Probability be 90%, " probability of corresponding " fast " words of one Pie Dian " of Shu Dian Dian second is 80% to strokes sequence, and similar principles can build and be based on The error correcting model of stroke.Stroke screening sequence and each pinyin string pair can also be judged according to the above-mentioned error correcting model based on stroke The matching probability of each word and/or word answered, if greater than threshold value, such as more than 60%, then it is believed that each pinyin string is corresponding each Word and/or word are matched.

Step 550, according to auxiliary strokes sequence and the matching result of the first strokes sequence, it is corresponding each to adjust each pinyin string The display location of word and/or word.

The embodiment of the present invention is due in double-spelling Chinese character input method, for the letter of a-z input by user, by the knowledge of double-spelling Chinese character input method Not, it is that corresponding pinyin string can be split as by the regulation of the initial and the final, and each pinyin string can correspond to different words, is spelled The combination of sound string can also correspond to different words, and the embodiment of the present invention can be clicked at an arbitrary position in user in entering method keyboard Input button corresponding with aided filter strokes sequence, then in keystroke sequence input by user, Direct Recognition user inputs Aided filter strokes sequence, so as to be filtered to the corresponding words of pinyin string below, reduce the selection model of follow-up character/word Enclose, so as to improve input efficiency.Also, the embodiment of the present invention can realize the filtering of strokes sequence, be not limited to single stroke Filtering.
