In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Referring to Fig.1, the step process for showing a kind of error correction method of search key of one embodiment of the invention is shown
It is intended to, can specifically include following steps:
Step 101, upon receiving a search request, the search key in described search request is obtained；
In embodiments of the present invention, searching request can be triggered by operation of the user in terminal device.Above-mentioned end
End equipment can be the mobile terminal devices such as mobile phone, tablet computer, be also possible to the equipment such as desktop computer, the present embodiment is to terminal
The type of equipment is not construed as limiting.
By taking operation of the user on mobile phone as an example.User can input corresponding search key, and point in search box
Beginning search button is hit, to trigger searching request.Certainly, the triggering of searching request can also by other means, such as when
User summarizes input search key and by cursor after removing in search box in search box, and terminal device automatic trigger is above-mentioned to search
Rope request, the present embodiment are also not construed as limiting the triggering mode of searching request.
Search key can be the word or word pair for embodying user's current search demand.It is searched when user inputs in search box
It after rope keyword, can indicate that user wishes that search engine is scanned for according to the keyword, and return to relevant search to user
Hitch fruit.
For example, search result may include introduction to keyboard, key when the search key of user's input is " keyboard "
The purchasing channel of disk, and how to choose a good keyboard etc..
Step 102, it whether determines in preset error correction dictionary comprising error correction keyword corresponding with described search keyword；
In embodiments of the present invention, error correction dictionary can be record user input error-critical word with after corresponding error correction
Keyword between corresponding relationship database.The database can be passing by statistic mass user search history next life
At.
For example, can recorde in error correction dictionary and its phase for some search key " key pan " in error correction dictionary
Corresponding error correction keyword " keyboard ".Above-mentioned corresponding relationship can indicate, when user is when inputting search key " key pan ",
Its true search need may be " keyboard ".Certainly, for different keywords, the error correction term recorded in error correction dictionary can
To include more than one, the present embodiment is not construed as limiting the quantity of the corresponding error correction term of search key of mistake.
In embodiments of the present invention, after getting the search key of user's input, above-mentioned error correction can be inquired first
Dictionary, confirms whether the keyword has corresponding error correction keyword in error correction dictionary.
If not including error correction term corresponding with the search key in error correction dictionary, it can be said that bright user is currently defeated
The search key entered is correct search term, without carrying out correction process to the keyword.For example, " keyboard ".
If including error correction term corresponding with the search key in error correction dictionary, it can be said that bright user is currently entered
Search key may be the search term of mistake, and the keyword is needed to carry out correction process.For example, " key pan ".
Include in error correction dictionary and when searching the corresponding error correction keyword of keyword, step currently can be executed when confirming
103, confirm the confidence level of the error correction keyword.
Step 103, the confidence level of the error correction keyword is determined；
In statistics, the confidence interval (Confidence interval) of a probability sample is to this sample
The interval estimation of some population parameter.What confidence interval showed is that the true value of this parameter has certain probability to fall in measurement result
Around degree.What confidence interval provided is the credibility for being measured the measured value of parameter, i.e., " certain required by front
Probability ".This probability is referred to as confidence level.Therefore, the confidence level of error correction keyword can be used for illustrating the error correction keyword
Credibility.In general, confidence level is higher, the confidence level of the error correction keyword is also higher；Conversely, confidence level is lower, then illustrate
The confidence level of the error correction keyword is also lower.
In embodiments of the present invention, the confidence level of error correction keyword can generate error correction dictionary, or some error correction is closed
Keyword is added to generation when in error correction dictionary, and is recorded in error correction dictionary.Therefore, when determining that some or certain several error correction close
When keyword, the confidence level of each error correction keyword can be directly extracted from error correction dictionary.
It should be noted that certain search keys may include multiple error correction keywords, each error correction keyword
To have a confidence level, which, which can embody, carries out the general of error correction to original search key using the error correction keyword
Rate.
Step 104, it is scanned for based on the confidence level and returns to corresponding search result.
In embodiments of the present invention, the confidence level of an error correction keyword can be simply divided into high confidence level and low
Different ways of search is respectively adopted then according to the difference of confidence level height in two kinds of situations of confidence level.
For the error correction keyword of high confidence level, can indicate that current search key has biggish probability is that user is defeated
Enter wrong, needs to carry out correction process to it using error correction keyword.At this point it is possible to directly adopt the progress of the keyword after error correction
It searches for and returns to search result.For example, " self ", corresponding error correction keyword " oneself " can have one in error correction dictionary
Higher confidence level can directly carry out error correction, and using after error correction when user is when input " self " scans for it
" oneself " scans for.
And for the error correction keyword of low confidence, it can indicate user's search key input mistake currently entered
Probability is smaller, and it is not absolutely required to carry out correction process to it using error correction keyword.At this point it is possible to according to former search key
Scan for and show in result of page searching error correcting prompt, with prompt the user whether to need to current search key into
Row correction process.For example, in error correction dictionary, " ten " corresponding error correction keyword " world " can have one and lower set
Reliability, when user is when input " ten " scans for, search engine can be carried out according to original search key " ten "
It searches for and returns to corresponding search result, and show error correcting prompt information in results page simultaneously, to prompt the user whether to need
Search is re-started according to " world " after error correction.
Certainly, the above confidence level by error correction keyword is divided into two kinds of situations of high confidence level and low confidence and carries out respectively
Search is a kind of example of the present embodiment, and those skilled in the art can according to actual needs, according to setting for error correction keyword
Reliability is scanned for using other modes, and the present embodiment is not construed as limiting this.
In embodiments of the present invention, upon receiving a search request, the search key in available searching request, and
It determines whether comprising error correction keyword corresponding with the search key in preset error correction dictionary, if including pair in error correction dictionary
The error correction keyword answered, then may further determine that the confidence level of the error correction keyword, be then based on the confidence of error correction keyword
Degree scans for and returns to corresponding search result.The present embodiment determines the need for the search inputted to user by confidence level
Keyword carries out correction process, and different confidence levels can embody the credibility of error correction keyword, so that search engine
The actual search need of user can be farthest matched according to confidence level, solve rely solely in the prior art editor away from
From the problem of error correction can not match user's actual search need is carried out, the efficiency and accuracy rate of search are improved.
Referring to Fig. 2, the step process of the error correction method of another search key of one embodiment of the invention is shown
Schematic diagram can specifically include following steps:
Step 201, error correction dictionary is generated；
In embodiments of the present invention, error correction dictionary can be record user input error-critical word with after corresponding error correction
Keyword between corresponding relationship database.The database can be passing by statistic mass user search history next life
At.
In embodiments of the present invention, the user conversation window of equipment can be obtained first.Above-mentioned user conversation window can be with
It is scanned for by record user using keyword and the information clicked to search result generates, above-mentioned keyword can wrap
Include search key and error correction keyword.
In general, user, when being scanned for using search engine, if the keyword of input is wrong, user can be actively right
It carries out correction process, then changes an other keyword and scans for, until obtaining satisfied search result.Therefore, it uses
Family session window can be used for recording the operation information of user in above process.
In the concrete realization, can by the UUID of equipment (Universally Unique Identifier, it is general only
One identification code) obtain above-mentioned user conversation window.UUID can uniquely determine an equipment, by obtaining on multiple devices
User conversation window, can determine user in search initially used in keyword after keyword and error correction, and be directed to
The click condition of the search result of different keywords.
It is then possible to be based on each UUID, counting user clicks initial search result corresponding with search key respectively
Number, and, click the number of corresponding with error correction keyword error correction search result, and initially search according to above-mentioned user click
The number of hitch fruit and the number of error correction search result, determine the confidence level of each error correction keyword.
In the concrete realization, it can determine the search key that user inputs in each user conversation window, count this and search
Whether rope keyword has corresponding search result to return, if the corresponding initial search result of the search key is sky, alternatively, with
The number of initial search result corresponding with the search key is clicked less than the first preset threshold in family, then can further count
User is after more preferable keyword scans for, and to the number of clicks of the search result of acquisition, searches to click error correction according to user
The number of hitch fruit determines the confidence level of above-mentioned error correction keyword.Generally, the confidence level of error correction keyword is clicked with user and is entangled
The number of wrong search result can have proportional relationship.
For example, can determine that the keyword is first after user inputs some keyword in search box and scans for
It is no that there is corresponding search result.If not with the search result of the Keywords matching, it may be considered that the keyword be mistake
Keyword accidentally.It, then can be further according to user to the search result if there is the search result with the Keywords matching
Click condition, determine whether the keyword correct.Specifically, if group of subscribers clicks the corresponding search result of the keyword
Number be less than certain numerical value, it is believed that the keyword may be mistake.It is closed at this point it is possible to continue counting user in replacement
After keyword scans for and obtains search result, to the click condition of search result.Then, according to user to the key after replacement
The click condition of the corresponding search result of word, determines the confidence level of the keyword.In general, click of the group of subscribers to search result
Number is more, then the confidence level of the corresponding error correction keyword of the search result is higher.
In embodiments of the present invention, after the confidence level for obtaining error correction keyword, original search key can be based on
Error correction dictionary is generated with corresponding error correction keyword and its confidence level.
Step 202, upon receiving a search request, the search key in described search request is obtained；
Step 203, it whether determines in preset error correction dictionary comprising error correction keyword corresponding with described search keyword；
Step 204, if so, determining the confidence level of the error correction keyword；
Step 205, if the confidence level is scanned for less than the second preset threshold using described search keyword, and
Show search result corresponding with described search keyword and the Correcting Suggestion information for the error correction keyword；
Step 206, it if the confidence level is more than or equal to second preset threshold, is carried out using the error correction keyword
Search, and show search result corresponding with the error correction keyword；
Since step 202 to step 206 is similar to step 104 with step 101 in above-described embodiment, can mutually refering to,
Therefore the present embodiment repeats no more step 202 to step 206, and concrete implementation mode may refer to step 101 to step 104
In record.
It should be noted that the corresponding error correction keyword of a search key may include multiple in error correction dictionary.
Therefore, when scanning for using error correction keyword, the corresponding target error correction term of the maximum value of confidence level can be determined first, so
It is scanned for afterwards using above-mentioned target error correction term, and shows search result corresponding with the target error correction term.
Step 207, according to the confidence level of the error correction keyword, the error correction dictionary is modified.
It in embodiments of the present invention, not only can searching according to user by obtaining the user conversation window of every equipment
Rope click condition determines error correction keyword and its confidence level, so that error correction dictionary is generated, it can also be according to each error correction keyword
Confidence level and its situation of change, above-mentioned error correction dictionary is modified, guarantee error correction dictionary accuracy.
In the concrete realization, after showing search result corresponding with error correction keyword, if user continues using original
Search key scans for, then can reduce the confidence level of the error correction keyword；When the confidence level of error correction keyword is less than
When three preset thresholds, for example, third predetermined threshold value can be 0, at this point it is possible to which above-mentioned error correction keyword is deleted from error correction dictionary
It removes.
For example, user is scanned for using some keyword, if system according to the suggestion of error correction dictionary, to the keyword
Correction process has been carried out, and has returned the search result scanned for according to error correction keyword to user.But if user does not have
Have and clicks the search result, but selection continues to scan for using original keyword, it may be considered that in error correction dictionary
The error correction keyword may be mistake, at this point it is possible to reduce the confidence level of the error correction keyword.When the confidence of error correction keyword
When degree is reduced to certain numerical value, such as the numerical value can be 0, then can delete the error correction keyword from error correction dictionary.
In embodiments of the present invention, by obtaining user conversation window, error correction dictionary can be generated, to carry out in user
When search, correction process can be carried out according to the error correction keyword recorded in the error correction dictionary.Since user conversation window can
Search history of the user under different search scenes is recorded, the correction process carried out according to error correction dictionary is obtained
The error correction keyword for meeting current search scene meets the actual search demand of user, improves the efficiency and accuracy rate of search.
In addition, can also be adjusted to the confidence level of each error correction keyword according to user conversation window, to realize to error correction term
The amendment in library further improves the accuracy of error correction dictionary.
