[embodiment]
Fig. 1 shows the flow process of an embodiment Chinese word input method, and the method flow process detailed process is as follows:
In step S10, obtain input string.
In step S20, judge that can input string carry out phonetic expansion, if so, enter step S40, otherwise enter step S30.In one embodiment, input string is carried out to syllabification, input string is carried out to syllabification and can realize according to existing syllabification method, after syllabification, obtain ultima, according to ultima, judge that can input string carry out phonetic expansion.When the ultima of input string may be the phonetic prefix of certain expansion syllable, judge that input string can carry out phonetic expansion.For example, get ultima for " on " after syllabification, it may be the phonetic prefix of " ong ", can carry out phonetic expansion; Again for example, get ultima for " h " after syllabification, it may be the phonetic prefix of " he ", " hong " etc., judges that it can carry out phonetic expansion.
In step S30, show that five words that input string is corresponding or pinyin word are as candidate word.In one embodiment, when input string can not carry out phonetic when expansion, according to the mixed defeated mode of normal five phonetics, process, show that five words that input string is corresponding or pinyin word are as candidate word.
In step S40, input string is carried out to phonetic expansion.Conventionally, the character string of user's input is not inputted completely, for example user's input " wozho ", that it may think input is " wozhong ", " wozhou " etc., but now in dictionary, can not find the pinyin word corresponding with input string, and when user is input to the 4th yard, at five phonetics, mix under defeated pattern, due to five four yards unique, can directly will on five corresponding input string words, shield, and cannot export user want input pinyin word.Therefore need input string to carry out phonetic expansion.Fig. 2 shows the method flow that in an embodiment, input string is carried out to phonetic expansion, and detailed process is:
In step S402, obtain the ultima of input string.Because syllable user above only inputs simplicity or input spelling conventionally, input string is carried out after syllabification, only need expand the ultima of input string.
In step S404, search the expansion syllable obtaining take ultima as phonetic prefix.In one embodiment, set in advance and stored the syllable list after all expansions and expanded the phonetic prefix list of syllable.For example, take syllable " a " as prefix, the syllable after corresponding expansion has " ao ", " ai ", " an ", " ang " etc.Getting after the ultima of input string, in the syllable list from the expansion of prior storage, searching the expansion syllable take ultima as phonetic prefix.For example, input string is " wzho ", and the expansion syllable finding take ultima " zho " as phonetic prefix is " zhong ", " zhou " etc.
In step S50, from dictionary, search pinyin word corresponding to input string after expansion, judge in dictionary whether have pinyin word corresponding to input string after expansion, if so, enter step 70, otherwise, enter step S60.In one embodiment, after the ultima of input string is expanded, the input string after being expanded.For example, in upper example, the input string after expansion is " wzhong ", " wzhou ".Search the pinyin word that input string after expansion is corresponding from dictionary before, need carry out syllabification to the input string after expansion, for example " wzhong " is divided into " w ' zhong ", and " wzhou " is divided into " w ' zhou ".Input string is carried out to syllabification can be realized according to existing syllabification method, at this, repeats no more.And to the simplicity in input string, can search all simple or compound vowel of a Chinese syllable of its correspondence, for example " w " finds " wo ", " wai ", " wa " etc.Afterwards, from dictionary, search obtain with expand after pinyin word corresponding to input string.
In step S60, show that five words corresponding to input string are as candidate word.In one embodiment, when searching in dictionary when with pinyin word corresponding to input string after expansion, illustrate that input string cannot phonetic identification, according to normal five-stroke input method processing, five words corresponding to demonstration input string are as candidate word.
In step S70, show that five words that described pinyin word and described input string are corresponding are as candidate word.In one embodiment, when in dictionary, can find with expand after pinyin word corresponding to input string time, show that the pinyin word finding is as candidate word, under the mixed defeated pattern of five phonetics, show that five words that described input string is corresponding are as candidate word simultaneously.
Demonstrate after candidate word, can be by corresponding Chinese character output according to user's selection.
Fig. 3 shows the flow process of another embodiment Chinese word input method, and the method flow process detailed process is as follows:
In step S100, obtain input string.
In step S200, judge that whether input string is input to the 4th character, if so, enters step S400, otherwise enters step S300.
In step S300, show that five words that input string is corresponding or pinyin word are as candidate word.Due to according to five-stroke input method, being input in the 4th yard, if four yards are unique, can directly above shield (being about to candidate word output), when being input to the 5th yard, automatically will in the acquiescence candidate word of four yards, shield.Therefore, input string outputed to before the 4th, all can process according to the mixed defeated mode of normal five phonetics, thereby show that five words that input string is corresponding or pinyin word are as candidate word.
In step S400, judge that can input string carry out phonetic expansion, if so, enter step S500, otherwise return to step S300.When input string can not carry out phonetic expansion, also according to the mixed defeated mode processing of normal five phonetics.
In step S500, input string is carried out to phonetic expansion.About the method for input string being carried out to phonetic expansion, can, with reference to as mentioned above, at this, repeat no more.
In step S600, from dictionary, search pinyin word corresponding to input string after phonetic expansion, judge in dictionary whether have pinyin word corresponding to input string after expansion, if so, enter step S800, otherwise enter step S700.
In step S700, show that five words corresponding to input string are as candidate word.
In step S800, show and search the pinyin word that obtains and/or five words corresponding to described input string as candidate word.Because input string has been input to four yards, four yards have five words of unique correspondence, show that five words that input string is corresponding are as candidate word, meanwhile, show that pinyin word that the input string searched after the phonetic expansion obtaining is corresponding is as candidate word.Like this, avoided owing to being input to four yards, pinyin string is not inputted complete and be there is no corresponding pinyin word, but five four yards unique upper screens, thereby can not get user and want the situation of the pinyin word of input.
Fig. 4 shows a character input system in embodiment, and this system comprises expansion judge module 10, phonetic expansion module 20, searches module 30, dictionary 40 and candidate word output module 50, wherein:
Expansion judge module 10, for obtaining input string, judges that can input string carry out phonetic expansion; When phonetic expansion module 20 can carry out phonetic expansion for determining input string when expansion judge module 10, input string is carried out to phonetic expansion; Search module 30 for from dictionary, search with expand pinyin word corresponding to input string; Dictionary 40 is for storing five words and pinyin word, and candidate word output module 50 is for showing that five words that the pinyin word that finds and input string are corresponding are as candidate word.
In one embodiment, expansion judge module 10 judges that can input string carry out phonetic expansion, if can, notify phonetic expansion module 20 to carry out phonetic expansion to input string, otherwise, according to the mixed defeated mode of normal five phonetics, process, by candidate word output module 50, export five words that input string is corresponding or pinyin word as candidate word.
Fig. 5 shows a phonetic expansion module 20 in embodiment, and this phonetic expansion module 20 comprises that syllable acquisition module 200, syllable search module 202 and expansion syllable memory module 204, wherein:
In one embodiment, search module 30 and from dictionary 40, search pinyin word corresponding to input string after expansion, and judge in dictionary 40, whether there be pinyin word corresponding to input string after expansion, if exist, 50 of candidate word output modules show that corresponding pinyin word is as candidate word, under the mixed defeated pattern of five phonetics, show that five words that input string is corresponding are as candidate word simultaneously; Otherwise, illustrate input string cannot phonetic identification, according to normal five-stroke input method processing, candidate word output module 50 shows that five corresponding words are as candidate word.Afterwards, the candidate word output that user can be selected.
In one embodiment, expansion judge module 10 is further used for when input string is input to the 4th character, obtains input string and judges that can described input string carry out phonetic expansion.Due to according to five-stroke input method, being input in the 4th yard, if four yards unique, can directly above shield (being about to candidate word output), when being input to the 5th yard, automatically will in the acquiescence candidate word of four yards, shield, therefore, input string outputed to before the 4th, all can process according to the mixed defeated mode of normal five phonetics, thereby show that five words that input string is corresponding or pinyin word are as candidate word.When the 4th character of input string input, the pinyin string of user's input may be imperfect, 10 of judge modules of expansion judge that can described input string carry out phonetic expansion, according to judged result notice phonetic expansion module 20, carry out phonetic expansion, described candidate word output module 50 is further used for when described input string can carry out phonetic expansion and can find pinyin word corresponding to input string after expansion from dictionary, searches five words that the pinyin word that obtains and/or input string are corresponding described in demonstration as candidate word.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
