This paper presents an personalized recommendation model to recommend potentially interesting resources to users based on the users' search behaviors and resource properties. This model builds on the user-based collaborative filtering technology and the top-N resource recommending algorithm, which consists of three parts: users' preference description, similar users' calculation and the resource recommending...
In this paper, a similarity evaluating model based on rough formal concept analysis and information content similarity is proposed which evaluates the similarity degree between the concepts. We use the information content approach to automatically obtain part of similarity scores of two concepts which makes up the normal featural and structural evaluating models. Then through our model, the similarity...
Although reputation models are available to encourage good services of sellers as well as punish their bad ones in the C2C ecommerce environment, their anti-fraud ability appears to be weak in general. Based on our TRUST model and the method of combing fraud pattern recognition with Time Window, we propose a Fraud Identification Method which has certain anti-fraud capabilities. Simulation experiments...
There are two principal ideologies in present digital library evaluation model. Divarication between them demonstrates the immaturity of evaluation research to some extent. To resolve such divarication can't only rely on the surface reference and complement from each other, but explore the intrinsic problem of divarication, then we can get ride of constraints and re-building a brand-new evaluation...
In this paper, We briefly present an overview of Markov chain Monte Carlo(MCMC), the MCMC method is studied with LA long beach air pollution PM 2.5 traffic from 2001 to 2007 observations. A linear regression model was built. We carried out statistical and graphical analysis and convergence diagnostics of Monte Carlo sampling output. The conclusion illustrated that the model fitting the datasets very...
As more and more people enter into the virtual world based on the internet, reputation has become the key to punish the bad behaviors of people and encourage the good behaviors of them. How to evaluate effectively the reputation of the participators is the urgent problem which should be solved. The paper provides a combined reputation model TRUST for distributed environment. This model, according...
