The rapid development of social networks has woven themselves into people's daily life and become indispensable platforms with superior commercial and scientific values. Both companies and governments have discovered the potential effectiveness of employing social network users for information diffusion. Rather than only selecting a group of users who are interested in target topic, it is more beneficial...
Friendship prediction in social networks is useful for various applications, such as friend/place recommendation and privacy management. In this paper, we propose a friendship prediction approach by fusing the topology and geographical features in location based social networks (LBSNs). We investigate the features of users' relationship both online and offline and quantify the contributions of selected...
This article introduces the main idea of decision-making behavior testing scenario management system. Based on the study of the classic experiments in theory of behavioral decision effect, testing scenarios are designed for testing decision-making behavior of business executives, and then a management system is developed to achieve dynamic management of testing scenarios. Behavioral decision theory...
This paper explores the problem of user experience evaluation, in particular the quantitative evaluation of group user experience, in the ubiquitous computing environments. Firstly, the classification and definition of four different categories of user groups are proposed and the notion of group user experience is introduced. Secondly, we analyze the quantitative evaluation of group user experience...
A new type of sensor with magnetic fluid (MF) for differential pressure, based on MFpsilas unique features of both liquidity and magnetic properties is introduced in this paper. A model of this sensor is given, and magnetic filed in the model is simulated and analyzed in this paper. The simulation results show that the theory inference is reliable. Some experimental studies on the sensor model are...
