In the present embodiment, step 101 is an optional step, and just the user can be to the processing of classifying of the interest point information in the interest point data base, can be not yet to the processing of classifying of the interest point information in the interest point data base.After the user is to interest point data base classification processing, interest point information after classification handled is as coupling retrieval source, the processing if the interest point information during the user does not classify to interest point data base is classified, then Mo Ren coupling retrieval source is all interest point informations in the interest point data base.
Step 102, obtain the phonetic tone of at least one Chinese character in the first letter of pinyin of at least two Chinese characters in the point of interest title to be checked of user input and at least two Chinese characters respectively.
At present embodiment, the user can be by 26 alphabet keys of A～Z and 4 input processes that digital keys comes completing steps 102 of 1～4, and being called " Wuhan University " with user's point of interest name to be checked below is that example is introduced following step.
At first analyze the first letter of pinyin and the phonetic tone of each Chinese character in " Wuhan University ", wherein the phonetic of " force " word is: WU, the phonetic tone is: falling tone.In the present embodiment, the first letter of pinyin of " force " word is: W, and the phonetic tone is: 3;
The phonetic of " Chinese " word is: HAN, the phonetic tone is: falling tone.In the present embodiment, the first letter of pinyin of " Chinese " word is: H, and the phonetic tone is: 4;
The phonetic of " greatly " word is: DA, the phonetic tone is: falling tone.In the present embodiment, the first letter of pinyin of " greatly " word is: D, and the phonetic tone is: 4;
The phonetic of " " word is XUE, and the phonetic tone is: rising tone.In the present embodiment, the first letter of pinyin of " " word is: X, the phonetic tone is: 2.
In the present embodiment, the user can import the first letter of pinyin and the phonetic tone of each Chinese character successively according to the order of Chinese character in the point of interest title, and concrete steps are as follows:
Step 201, obtain the first letter of pinyin and the phonetic tone of each Chinese character in the point of interest title to be checked of user input successively;
Just, at first obtain the first letter of pinyin of first Chinese character of user input and the phonetic tone of first Chinese character; Obtain the first letter of pinyin of second Chinese character of user input and the phonetic tone of second Chinese character then; For example: at first obtain the first letter of pinyin and the phonetic tone of user's input " force " word, the character string of promptly obtaining input is " W3 ", obtains the first letter of pinyin and the phonetic tone of user's input " Chinese " word then, and the character string of promptly obtaining input is " H4 ";
Step 202, judge whether also to need to import the first letter of pinyin and the phonetic tone of other Chinese characters in the point of interest title to be checked, if, continue the first letter of pinyin and the phonetic tone of other Chinese characters in the input point of interest title to be checked, the first letter of pinyin of all Chinese characters and phonetic tone in obtaining point of interest title to be checked; Otherwise, finish obtaining step.
Just, judge the first letter of pinyin and the phonetic tone that whether also need to import other Chinese characters in " Wuhan University ", can find that by execution in step 201 first letter of pinyin and the phonetic tone of " university " two Chinese characters need input in addition, continue the first letter of pinyin and the phonetic tone of input " greatly " word this moment, be input of character string " D4 ", the first letter of pinyin and the phonetic tone of input " " word, be input of character string " X2 ", after character string " W3H4D4X2 " input finishes, can judge obtaining step 102 is finished, mate the Chinese character retrieval phrase according to the character string " W3H4D4X2 " of input then, promptly execution in step 103.
Certainly, in the present embodiment, the user also can import the first letter of pinyin of each Chinese character at first successively according to the order of Chinese character in the point of interest title, after the first letter of pinyin input of Chinese character finishes, imports the phonetic tone of each Chinese character more successively, and concrete steps are as follows:
Step 301, obtain the first letter of pinyin of Chinese character in the point of interest title to be checked of user input successively;
Just, obtain the first letter of pinyin of " Wuhan University " middle Chinese character of user's input successively, the character string of promptly obtaining is " WHDX ";
Step 302, according to point of interest title to be checked, judge whether to obtain the first letter of pinyin of other Chinese characters in the point of interest title to be checked of user's input, if, continue to obtain the first letter of pinyin of other Chinese characters in the point of interest title to be checked of user's input, the first letter of pinyin of all Chinese characters in obtaining point of interest title to be checked, otherwise, obtain the phonetic tone of Chinese character in the point of interest title to be checked of user input successively.
Just, judge whether to obtain the first letter of pinyin of other Chinese characters in the point of interest title to be checked of user's input according to point of interest title " Wuhan University " to be checked, if, continue to obtain the phonetic alphabet of other Chinese characters, the input of the first letter of pinyin of all Chinese characters finishes in point of interest title to be checked, first letter of pinyin owing to all Chinese characters in " Wuhan University " that obtained user's input in the step 301, next, can import the phonetic tone of Chinese character in " Wuhan University " successively, i.e. input of character string " 3442 ".After character string " WHDX3442 " input finishes, can judge obtaining step 102 and be finished, remove match retrieval Chinese character phrase according to the character string " WHDX3442 " of input then, promptly execution in step 103.
In the present embodiment, the capital and small letter of first letter of pinyin is general, and promptly A is equal to a, and a is equal to A, so the user both can import the first letter of pinyin of capitalization, also can import the first letter of pinyin of small letter.
Step 103, according to the phonetic tone of at least one Chinese character in the first letter of pinyin of at least two Chinese characters obtaining and at least two Chinese characters, in default interest point data base, mate retrieval with community string index community, must with the Chinese character phrase to the point of interest title of point of interest name-matches to be checked.
In the present embodiment, can adopt fully coupling retrieval or fuzzy matching retrieval, when adopting coupling retrieval fully, character string default in the character string of having only input and the community string index community is one by one at once, and just the match is successful in judgement, otherwise be that it fails to match.When for example the user has only correct input of character string " W3H4D4X2 ", " WHDX3442 " and " W3%D4X2 ", could mate retrieval by step 103 and obtain " Wuhan University ", because what adopt is to mate retrieval fully, therefore can effectively improve the accuracy of phonetic retrieval, wherein community string index community " W3%D4X2 " can mate with the character string " W3D4X2 " of user's input.
Certainly in order to simplify the operation, also can adopt the fuzzy matching retrieval, just character string and the community string index community with input carries out fuzzy matching.
In this enforcement, the user can import the first letter of pinyin of at least two Chinese characters, phonetic tone with these at least two Chinese characters, be that the character string that the user imports is " W3H4 ", can judge the character string " W3H4 " and community string index community " W3H4D4X2 " fuzzy matching of input this moment by the fuzzy matching retrieval, and also can obtain " Wuhan University " by step 103 coupling this moment.
In the present embodiment, the user also can import the first letter of pinyin of at least two Chinese characters, the phonetic tone of at least one Chinese character at least two Chinese characters, be that the character string that the user imports is " W3H ", can judge the character string " W3H " and community string index community " W3H4D4X2 " fuzzy matching of input by the fuzzy matching retrieval equally, thereby also can obtain " Wuhan University " by step 103 coupling.
When the user only imports the phonetic tone of at least one Chinese character at least two Chinese characters, the phonetic tone that this phonetic tone can be first Chinese character, it also can be the phonetic tone of second Chinese character, when the user selects to import the phonetic tone of second Chinese character, the character string that the user need import is " WH4 ", also can judge the character string " WH4 " and community string index community " W%H4DX4 " fuzzy matching of input this moment by the fuzzy matching retrieval, and wherein character " % " is an asterisk wildcard.Owing to reduced the character string number of user's input, thereby can improve the efficient of phonetic retrieval.
