To reach this, they first collect ratings on something from a large number users, and then perform the calculation through some algorithms. The algorithms, however, don't take the credibility of user himself into consideration. The paper proposes a ranking model based on user's credit, which takes user's credit as his weight integrated into his rating, and thus information submitted by different users has different effectiveness. The steps to implement this is firstly to cluster users by K-means to find out senior users, then to evaluate something synthetically by Attribution Coordinate Synthetic Evaluation on condition that senior users' rating is weighted, and finally to get ranking list. The simulation for film recommendation validates the model for recommendation system.","PeriodicalId":126161,"journal":{"name":"IEEE International Conference on Granular Computing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125772376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed method employs the hierarchical evaluation method based on fuzzy rules and artificial neural networks. The proposed method integrates the fuzzy logic and the artificial neural networks, which overcomes the shortcomings of redundant fuzzy rules. The evaluation index system is determined based on the universal principle and the research fruits of the former scholars home and abroad. We build a fuzzy neural network evaluation model to achieve the final evaluation goal of the digital resources. In addition, to evaluate the performance of the proposed approach, we compare its results with GRA-BPN model.

Nevertheless, there are flaws of selecting the weight of upper and lower approximation, defining the density of samples and searching the center in the Rough K-means Clustering Algorithm with Weight Based on Density. Aiming at the flaws, this paper proposes a solution to search initial central points and combines it with a distance measure with weight which is based on attribute reduction of rough set to achieve the algorithm. This improved algorithm decreases the level of interference brought by the isolated points to the k-means algorithm, and makes the clustering analysis more effective and objective. This experiment was performed by testing the true data sets. The results showed that the improved algorithm is effective, especially to those data sets with huge redundance.","PeriodicalId":126161,"journal":{"name":"IEEE International Conference on Granular Computing","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131733482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
