Collaborative filtering recommendation method based on user clustering and project association analysis

The invention discloses a collaborative filtering recommendation method based on user clustering and project association analysis in order to solve the problems of cold start, data sparseness, low recommendation accuracy and the like of a traditional collaborative filtering recommendation algorithm. According to the method, an improved fuzzy C-means clustering algorithm is adopted to mine the preference degree of hidden features of a user, and an association analysis strategy based on pre-judgment screening is adopted to screen a frequent item set. On the basis, the algorithm uses a user characteristic preference matrix and a user scoring matrix to calculate the similarity between users, uses a frequent item set matrix and a user scoring matrix to calculate the similarity between items, and combines the user similarity and the item similarity to calculate the prediction score of the users for items which are not scored, thereby realizing Top-K recommendation. Compared with a traditional collaborative filtering recommendation algorithm based on a user and a collaborative filtering recommendation algorithm based on a project, the method can effectively avoid the cold start problem and the data sparsity problem, and has better recommendation quality.
