Claim 9:
10. A community question-answer website answer sorting system combined with active learning, comprising: a memory; a processor; a question-answer data representation module configured for extracting text features of the question-answer data, and expressing a question title and answer content after word segmentation and stop word removal as a word vector matrix; calculating a community feature of the question-answer data based on community data related to question-answer, mapping a total number of approval answers to a question and a number of user answers to (0,1) through a question long tail factor and a user long tail factor, multiplying the community feature of the question-answer data by the question long tail factor and the user long tail factor to replace an original community feature of the question-answer data, and inputting the community feature of the question-answer data into a Community Question Answering-Convolutional Neural Network (CQA-CNN) model to represent the question-answer data as a distributed vector; a training set construction and answer sorting module configured for performing statistical analysis on a question-answer data set, formalizing a statistical result into rules, and automatically constructing a preliminary labeled training set based on the rules; constructing a answer sorting model based on the CQA-CNN model, and predicting a sorting relationship between any two candidate answers; constructing an unlabeled training set, and selecting an additional sample from the unlabeled training set for manual labeling by combining active learning; merging labeled results into the preliminary labeled training set to retrain the answer sorting model, and using the answer sorting model after retraining for community question-answer website answer sorting.
