Stephen Wolfram, creator of Mathematica (which I used to use a lot) and author of A New Kind of Science, blogged about his current project, Wolfram|Alpha. The web site won’t fully launch till May, and his blog post is lacking in details, but the project seems to be some combination of search engine, natural language processing, and expert-curated semantic models. Definitely something to watch.
Yahoo Developer Network has a new video on how they use Hadoop to analyze and filter spam. This is part 1 of a series, and it’s just background info on the size of their spam problem and how Hadoop is more scalable than their previous DB solution. Hopefully future episodes will have more meat.
