Understanding the Impact of Geographical Distance on Online Discussions 
IEEE Transactions on Computational Social Systems  
Discussion topics, geographical distance, location(country), online content, topic classification 
People in geographically close areas tend to show similarities in their interests such as sports, food, and festivals, which is often reflected in their discussion. Lifestyle and the way of communication among people living nearby play an essential role in this similarity. However, with the popularity of online social media platforms, communication with distant persons has become much easier and frequent. In one sense, social media platforms help in breaking the barrier of distance and bring people across geography closer. With this, a comprehensive study is required to understand whether geographical distance still has a significant impact on discussion or it has already faded and made us a global citizen. Moreover, if there is an impact of geographical distance on discussion, then it would be interesting to investigate whether this impact is uniform across different topics of discussion or not. This understanding will help in targeted marketing, advertisement, and policy-making. In this article, we analyze the geotagged tweet data collected for a period of around five months for three countries, USA, U.K., and India, each with diverse cultures and unique identities. We measure the impact of geographical distance at a finer granularity (within a country) in online discussions in terms of content similarity and other geographical parameters of topical tweets. This article reflects that there is a significant homogenization in online discussions with respect to geographical distance; however, this homogenization is not similar across all the topics of discussion and location. The impact varies depending on the topic of discussion and location.

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.
