The Pareto principle (also known as the 80/20 rule) states that about 80% of the consequences are created by 20% of the causes. In this paper we describe the distribution of several aspects of YouTube, a website used for online video sharing, to see if the Pareto principle applies to these aspects. These aspects include the views and comments of videos, and the videos uploaded and comments post...

Speech transcription of web videos requires first detecting segments with transcribable speech. We refer to this as segmentation. Commonly used segmentation techniques are inadequate for domains such as YouTube, where videos may have a large variety of background and recording conditions. In this work, we investigate alternative audio features and a discriminative classifier, which together yie...

Detailed data on the recreational use of drugs are difficult to obtain through traditional means, especially for substances like Dextromethorphan (DXM) which are available over-the-counter for medicinal purposes. In this study, we show that information provided by commenters on YouTube is useful for uncovering the toxicologic effects of DXM. Using methods of computational linguistics, we were a...

Our characterization is over 3.4 million videos and 400,000 video responses collected from Y...
