In this lecture, Austin presented his project about Image Tagging Networks. Tags are keywords that link to a resource like an image, video, web page, or blog. They are usually entered by users without using a controlled vocabulary. They help to improve search, organization, spam detection, and repudiation systems. Austin will focus on Flickr and using its API to see if there is any correlation between image popularity and tags. Previous work consists of Yahoo Research and the UC Berkley School of Information. They found that most tags were unclassified, but those that were contained location or "other" keywords.
Next, Guoxun presented his project on aerosol networks. Aerosol is an important study because many pollutants are aerosols and they can have an affect on climate change, health, and the economy. Aerosols are an important global problem because they can travel on trade winds. Guoxun will focus on California and how ozone is transported across the state. Previous work consists a study of Clark County Air Quality in March of 2006 by Robert A. Baxter of T&B Systems. The concentration of ozone increased during commuter hours and was spread widely across the state by winds.
