Public Display as Communication Tool for a Co-Located Community

We studied the use of multiple public displays deployed throughout North Quad Residential Hall at University of Michigan. These displays are largely being used for broadcasting official news and provoking informal interactions between residents. Our paper is focused towards use of displays as a communication channel. In particular, our research covers three aspects related to this variation of public displays. Firstly, we determined the impact of using digital displays as a communication channel on other existing channels. Secondarily, we studied the origin and impact of ubiquity created by these devices. Lastly, we observed privacy issues that people have while posting content and thereby establishing their need for a brief awareness of the audience. We conclude by establishing the need for further study of public displays as a communication channel.

Design Suggestions for improving the community experience of XBox-Live

This paper suggests design alternatives for the Xbox Live Community that supports communal interactions through forums, events and reputation scores. The design suggestions are organized into five distinct sections. First section is focused at startup challenges that a newly formed sub-community might face. The second section suggests ways to attract newcomers who would be beneficial to the community. Third section targets sustainability of the community by increasing individual's identity-based commitment. Fourth section looks at tools and practices that could foster peer-to-peer regulation within the community. The last section provides methodologies that could improve quality of an individual's contribution.

Medicine Recommender System for the purpose of suggesting new and alternative medicines

This paper contains reflection of concepts that were taught in SI 583 – Recommender Systems course and an approach to apply these concepts into a new domain for coming up with an efficient recommender.Recommender Systems has been extensively applied to e-commerce websites (Amazon.com) but its application in other domains is very limited. This paper uncovers one such domain, i.e. application of recommender systems for recommending medicines to patients. The medical application of the recommender systems would not only allow one to make wise decisions while purchasing medicines but would also provide a platform for global collaboration of medical experience between doctors.

Network Analysis and Marketing Techniques: Twitter as a Viral Marketing Tool

Our motivation to conduct this analysis was to provide a method for any organization to analyze their social network. In a very short time, Twitter's growth curve has shown a sharp increase from an obscure segment of the web to a must-have for business identities. Twitter proves itself highly useful for individuals and organizations to connect and exchange information. While there are plenty of concerns (e.g., security, management, and interruptions issues) there are also benefits for organizations using the social networking site. Many of these advantages deal with the real-time spreading and gathering of information. Other benefits include gaining competitive intelligence, brand awareness, feedback mechanisms, and human resources assistance.
