Claim 6:
7. The community question-answer web site answer sorting method combined with active learning according to claim 1, wherein: in step 2, after the statistical analysis on the question-answer data set, three rules are obtained and formalized; firstly, in the CQA web site, under a same question, optimal answers are ranked higher than non-optimal answers; secondly, in the CQA web site, under the same question, there is no difference in sorting order between non-optimal answers; and finally, in the CQA website, the answers to questions in a same field as the target questions are ranked higher than those to questions in a different field from the target questions; the above three rules are formalized as follows:

(qi,(qi,ail)(qi,(qi,aim))

(qi,(qi,ain))≅(qi,(qi,aim))

(qi,(qj,ajn))(qi,(qk,aim))

where m≠1, n≠m, and the symbol  indicates that for the target question qi, a candidate question-answer pair (qi, ail) is ranked higher than a candidate question-answer pit (qi, aim), that is, a sorting label is 1, and the symbol ≅ indicates that for the target question qi, there is no sorting relationship between the candidate question-answer pair (qi, aiu) and the candidate question-answer pair (qi, aim), that is, the sorting label is 0;
a program is designed to automatically construct the labeled training set L based on the three formalized rules.
