Embodiment
The embodiment of the present application provides a kind of Search Hints method and system, be used for to solve the Search Hints information that prior art exists and the misspelling information is inaccurate or option problem seldom.
Below in conjunction with Figure of description and concrete embodiment technique scheme is described in detail and sets forth.
Embodiment 1
As shown in Figure 1, the embodiment of the present application one provides a kind of method that makes up the prompting dictionary, specifically comprises:
For step 101, based on original dictionary, generate original even numbers group dictionary by even numbers group algorithm, its building process is as follows:
Traveling through at first that whole dictionary is converted into all words with the byte is the Trie tree (dictionary tree) of unit.
Make up the even numbers group then, building process mainly contains following step:
1, initialization active node tabulation adds tabulation to the ground floor node.With base[] array and check[] element of array is initialized as 0, as base[i]=check[i]=represent that this position is for empty 0 the time, as base[i] value be expressed as a state that can finish during for negative value, especially as base[i]＜represent that this node is leaf node during 0 and abs (base[i])=i.
If 2 effort scales are not empty, choose in the Trie tree directly that the maximum node of son node number is present node, finish otherwise make up.
3, visit the subscript position that this node determines its base value and determines direct child node, making the value of each direct child node in the check array is the subscript value of present node.
4, current direct child node is added effort scale, repeating step 2.
As shown in Figure 2, the method as embodiment one provides for step 102, based on original even numbers group dictionary, generates the Search Hints dictionary, specifically comprises:
Step s102a based on original even numbers group dictionary, generates and treats sorted search prompting dictionary; Word prefix according to user input provides complete cue, because the identical word of prefix has a lot, so need sort from high to low to the identical word of prefix according to the marking standard, generates and treats that sorted search points out dictionary.
Step s102b, by the first marking standard, candidate's cue for the treatment of in the sorted search prompting dictionary is given a mark, and obtains the score value of each candidate's cue;
The first marking standard comprises following factor:
1, the word frequency nCorpus of this word in language material, weight is CorpusWeight;
The frequency nHour that this word is imported by the user in 2, one hours, weight is HourWeight;
The frequency nDay that this word is imported by the user in 3, one days, weight is DayWeight;
The frequency nMonth that this word is imported by the user in 4, one months, weight is MonthWeight.
The marking formula is:
Score?1＝CorpusWeight*nCorpus+HourWeight*nHour+DayWeight*nDay+
MonthWeight*nMonth。
Step s102c presses score value from high to low, and ordering candidate cue obtains the Search Hints dictionary.
Step s102c specifically comprises:
Press score value from high to low, described candidate's cue sorts;
From described candidate's cue, obtain score value greater than candidate's cue of a default score value;
Described score value is preset candidate's cue of score value as described Search Hints dictionary greater than one.
Obtain after the mark of candidate's cue, suppose that this default score value is X, then the candidate cue of score value greater than the X correspondence extracted, as the cue in the Search Hints dictionary.
As shown in Figure 3, as embodiment one described method, step 103, based on described original even numbers group dictionary, generate misspelling prompting dictionary, the realization principle of misspelling prompting dictionary is with the realization principle of Search Hints dictionary, make up misspelling prompting dictionary based on even numbers group dictionary, the prompting dictionary is by phonetic--cue is corresponding, and with the pronunciation ID generation Chinese character-pronunciation ID dictionary of Hanzi internal code correspondence, it realizes that principle is integer array that length is Length=65536 (1＜＜16) of application, its subscript value is the ISN of Chinese character correspondence, element value is pronunciation ID, and the method that it generates misspelling prompting dictionary specifically comprises:
Step s103a based on described original even numbers group dictionary, generates with parallel the waiting of the described original even numbers group dictionary misspelling that sorts and points out dictionary;
Step s103b by the second marking standard, gives a mark to the candidate's cue in the described misspelling dictionary of waiting to sort, and obtains the score value of each candidate's cue; The second marking standard is identical with the first marking standard, and the marking standard of each word is comprised following factor:
1, the word frequency nCorpus of this word in language material, weight is CorpusWeight;
The frequency nHour that this word is imported by the user in 2, one hours, weight is HourWeight;
The frequency nDay that this word is imported by the user in 3, one days, weight is DayWeight;
The frequency nMonth that this word is imported by the user in 4, one months, weight is MonthWeight.
The marking formula is:
Score?2＝CorpusWeight*nCorpus+HourWeight*nHour+DayWeight*nDay+
MonthWeight*nMonth。
Step s103c presses score value from high to low, and the described candidate's cue that sorts obtains misspelling prompting dictionary.
Pronunciation ID string in the misspelling prompting dictionary is pronunciation to be converted into ID represent, the benefit of doing like this is can not produce to search ambiguity, information such as user's input is " Xian ", just can not judge only according to phonetic what corresponding Chinese character is, can be " line earlier; existing ... ", also can be " Xi'an ".We are converted into corresponding ID with the phonetic of individual character in order not produce this class problem, so just can avoid the problem of producing ambiguity as " xi=1, an=2, xian=3 ".The phonetic of all words is set up the even numbers group after being converted into pronunciation ID string, generates parallel with it the 3rd array misspelling prompting dictionary simultaneously and preserves the misspelling information.
Wherein, describedly press score value from high to low, the described candidate's cue that sorts obtains misspelling prompting dictionary, specifically comprises:
Press score value from high to low, described candidate's cue sorts;
From described candidate's cue, obtain score value greater than candidate's cue of a default score value;
Point out dictionary greater than candidate's cue of a default score value as described misspelling with described score value.
If the user imports " hundred cross ", after system's marking ordering is finished, if the cue order Baidu from high to low that obtains, ferry-boat, Baidu, system can point out out so: 1, Baidu; 2, ferry-boat; 3 cue such as have the honour to read, and select for the user, have so just avoided the user to cause the Query Result failure because of the mistake input.
