Partial user-supplied information and user modeling for improving QoS?. Rodrigo Verschae, Mario Köppen and Kaori Yoshida. Simulation Modelling Practice and Theory, 19(1):47-55, January 2011. (URL)

Abstract

The incorporation of user-supplied information has become mandatory for the improvement of QoS? in network systems. There is the question about accommodation of new users of a service, given that information about former users of a service is available. In the present work, we followed two approaches to derive information about new users in the network design and control processes, where both are based on prototype generation for the answers of former users to a QoS? related questionnaire. In the first approach, attempts were made to map user attributes to prototypes. The second approach used a mapping from partial answers to a prototype. As a result, the first approach appeared to be infeasible, while the second showed good results. In the resulting trade-off between number of prototypes and classification accuracy, it is possible, for example, with 8 prototypes for around 1000 users to predict the answers of new users by using only 30% of the answers of former users, while reducing accuracy by only 13% at the same time.
