To illustrate the point that Bob made in class about tagging and controlled vocabularies, you may want to take a look at SociallyDelicious. Prateek, Yo-Shang and I created this tool last year in IOLab. The main idea is to see show people tag bookmarks in del.icio.us and whether their tagging behavior is influences by their level of expertise.

This week's New Yorker recently featured an interesting article about phone books. Once a source for information retrieval, "its legitimacy as a reference tool was undermined long ago-- first by 411, then by the Internet and smartphones."

In an attempt to reduce spam, scams, and the spread of pornography via cell phone, the Chinese government is requiring citizens and visitors to provide identification when purchasing a SIM card. Working with government-control telecom companies, convenience store owners and street vendors, China hopes to organize a system in which all cell phone numbers and SIM cards can be linked to an individual.

In his legendary TED talk, Hans Rosling, a global health researcher from Sweden, presents a tool called "Gapminder" which uses a simple and intuitive visualization of complex macroecononmic information to clearly point out particular global trends. This tool (available online) has access to a bulk of information about almost all countries in the world regarding GDP, HIV, CO2 emissions etc. starting from 1800. Rosling successfully bridges the gap by providing an interactive interface that allows the exporation of vast data sets in an intuitive and entertaining way.

As with just about everything for which one would create an ontology, the beer ontology could have been done a few different ways, but I actually think having fermentation style on the first level works well and seems logical (to me, anyway, as someone who has a few batches of homebrew under my belt). However, there are a few picky points of contention. "Bitter" doesn't really belong in its own alongside those styles because a bitter beer is usually a heavily hopped pale ale, and since you include pale ale as its own term, then bitter could spring from that.
