A Probabilistic Graphical Model For Topic And Preference Discovery On Social Media, Lu Liu, Feida Zhu, Lei Zhang, Shiqiang Yang Oct 2012

A Probabilistic Graphical Model For Topic And Preference Discovery On Social Media, Lu Liu, Feida Zhu, Lei Zhang, Shiqiang Yang

Research Collection School Of Computing and Information Systems

Many web applications today thrive on offering services for large-scale multimedia data, e.g., Flickr for photos and YouTube for videos. However, these data, while rich in content, are usually sparse in textual descriptive information. For example, a video clip is often associated with only a few tags. Moreover, the textual descriptions are often overly specific to the video content. Such characteristics make it very challenging to discover topics at a satisfactory granularity on this kind of data. In this paper, we propose a generative probabilistic model named Preference-Topic Model (PTM) to introduce the dimension of user preferences to enhance the …

When Antitrust Met Facebook, Christopher S. Yoo Jul 2012

When Antitrust Met Facebook, Christopher S. Yoo

All Faculty Scholarship

Social networks are among the hottest phenomena on the Internet. Facebook eclipsed Google as the most visited website in both 2010 and 2011. Moreover, according to Nielsen estimates, as of the end of 2011 the average American spent nearly seven hours per month on Facebook, which is more time than they spent on Google, Yahoo!, YouTube, Microsoft, and Wikipedia combined. LinkedIn’s May 19, 2011 initial public offering (“IPO”) surpassed expectations, placing the value of the company at nearly $9 billion, and approximately a year later, its stock price had risen another 20 percent. Facebook followed suit a year later with …


Beyond Coase: Emerging Technologies And Property Theory, Christopher S. Yoo Jun 2012

Beyond Coase: Emerging Technologies And Property Theory, Christopher S. Yoo

All Faculty Scholarship

In addition to prompting the development of the Coase Theorem, Ronald Coase’s landmark 1959 article on the Federal Communications Commission touched off a revolution in spectrum policy. Although one of Coase’s proposed reforms (that spectrum should be allocated through markets) has now become the conventional wisdom, his other principal recommendation (that governments stop dedicating portions of the spectrum to particular uses) has yet to be fully embraced. Drawing on spectrum as well as Internet traffic and electric power as examples, this Article argues that emerging technologies often reflect qualities that make defining property rights particularly difficult. These include the cumulative …


Network Neutrality And The Need For A Technological Turn In Internet Scholarship, Christopher S. Yoo May 2012

Network Neutrality And The Need For A Technological Turn In Internet Scholarship, Christopher S. Yoo

All Faculty Scholarship

To most social scientists, the technical details of how the Internet actually works remain arcane and inaccessible. At the same time, convergence is forcing scholars to grapple with how to apply regulatory regimes developed for traditional media to a world in which all services are provided via an Internet-based platform. This chapter explores the problems caused by the lack of familiarity with the underlying technology, using as its focus the network neutrality debate that has dominated Internet policy for the past several years. The analysis underscores a surprising lack of sophistication in the current debate. Unfamiliarity with the Internet’s architecture …


The Practicality Of Cloud Computing, Xiaohua (Cindy) Li Jan 2012

The Practicality Of Cloud Computing, Xiaohua (Cindy) Li

Librarian Publications

Since its inception, cloud computing has become the current paradigm. Organizations of different size and type have embraced the concept because of its both technological and economic advantages. Sacred Heart University Library has recently published its newly designed website on the cloud. For a small academic library, what does it mean to put their online data on the cloud? This paper will analyze and discuss the advantages of cloud computing, and some potential obstacles created by it through the author’s observations. This paper hopes the uniqueness of the case will contribute to the improvement of cloud computing experience of other …
