Recommendation method based on singular value decomposition and classifier combination

The invention discloses a recommendation method based on singular value decomposition and classifier combination. The recommendation method comprises the steps of computing average score and probability distribution of an item through data preprocessing; training a singular value decomposition model through a stochastic gradient descent method, computing an entropy set of a scored item set of the user in item classification through a computing method of entropy, and determining an uncertainty critical value of the item; and comparing and predicting uncertainty and critical value of the item to determine whether to use a classifier, and recommending N items with highest scores in all non-scored items of the user through a Top-N method. According to the method, individual recommendation is produced on the basis of analysis of historical score data of the user; predicting score of a designated item i is acquired through a singular value decomposition algorithm, information entropy of the item for each user is calculated so as to determine whether to classify, and final prediction score of the item is acquired through the classifier, so that the accuracy of the recommendation method is improved.

Subjective question scoring model and scoring method based on deep learning BERT-CNN

The invention discloses a subjective question scoring model and scoring method based on deep learning BERT-CNN. The subjective question scoring model comprises a BERT conversion word vector matrix module, a CNN semantic feature extraction module, a similarity calculation module and a scoring module, wherein the BERT conversion word vector matrix module is used for converting an answer text into aword vector matrix, and then transmitting the word vector matrix of each answer to the CNN semantic feature extraction module; the CNN semantic feature extraction module is used for acquiring a semantic feature vector of the answer text, includes a convolution layer and a pooling layer, and is used for obtaining semantic feature vectors of the answer texts and then transmitting the signals to thesimilarity calculation module for calculating a similarity value between the answer text semantic feature vectors and transmitting the similarity value to the scoring module for determine the score ofthe answer text. The subjective question scoring model is applied to subjective question scoring, can effectively reduce the labor cost, and can solve the problems that due to the fact that only keyword matching is carried out in manual scoring, the scoring result is inaccurate, and scoring is not fair.

Score prediction method and device, computer equipment and storage medium

The invention relates to a score prediction method and device, computer equipment and a storage medium. The score prediction method comprises the steps: receiving a user ID and an article ID, and obtaining a user preference feature, an article preference feature, comment information corresponding to a user, and comment information corresponding to an article; obtaining a text feature matrix corresponding to the comment information; obtaining comment information usefulness according to the text feature matrix, the user preference features and the article preference features, and obtaining swarmintelligence features according to the comment information usefulness and the text feature matrix; mapping the user preference features and the article preference features to a feature space of the swarm intelligence features to obtain user hidden features and article hidden features; and obtaining a prediction score of the user for the article. According to the score prediction method, the groupintelligence features are obtained through the comment information of the users and the articles, and then the hidden features of the articles are extracted through the group intelligence features toobtain the matching scores of the users and the articles, and the scoring accuracy of the recommendation system can be effectively improved.

The invention relates to a dynamic extensible voice quality inspection scoring method. The method comprises the steps of acquiring recording audio data of an object subjected to quality inspection, converting the acquired recording audio data into text data in a text format, converting the text data into a voice oscillogram, detecting service taboo languages according to the text data, generatinga first score deduction value; and detecting emotion abnormality according to the voice oscillogram, generating a second score deduction value, obtaining a quality inspection score of the recorded audio data according to the first score deduction value, the second score deduction value and the full score, and feeding back a judgment result of the quality inspection score, service taboo languages existing in the text data and whether the recorded audio data has abnormal emotion or not. The voice quality inspection scoring method is an automatic quality inspection scoring method, does not need to specially set quality inspection personnel, further avoids the problem of large quality inspection workload, reduces personnel investment cost, avoids loss of scoring fairness due to subjective judgment of the quality inspection personnel, and is relatively high in accuracy.
