Abstract:
The last couple of years have witnessed a huge surge in usage of the Internet due to the availability of several interactive applications of Web 2.0. Growth in both web users and varieties of online objects has been observed. In this paper, we propose a growth model for online emerging user–object bipartite networks to investigate selection behaviors of web users. According to model, both sets of users and objects grow constantly but edges arrive only from user set. The network evolves by arrival of external edges brought by new users and/or internal edges from old users. These external and internal edges are attached with a combination of preferential and random attachment mechanism. We have considered different attachment procedures for external edges of new users and internal edges of old users. To validate our model, we have taken nine different real online networks with distinct objects. Our results show good agreement between empirical data and theoretical model. We report mean absolute deviation (MAD), mean square error (MSE) and root mean square error (RMSE) for the proposed growth model. We emphasize on significant inferences about selection behaviors of web users after interpreting parameters’ values of the model. We also report detailed analysis of randomness in selection of new and old users that gives interesting inferences for each of the considered online networks.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
