The launch of Wolfram Alpha in May is still one of the most exciting product launches we have witnessed so far this year, even if the enormous hype around it also meant that it disappointed a lot of people who expected a "Google killer." In the last couple of months, however, the Wolfram Alpha team has been working quietly on improving Wolfram's 'computational knowledge engine.' According to Stephen Wolfram's latest post on the Wolfram Alpha blog, things are moving ahead as planned. The company has used the summer months to tweak and extend Wolfram Alpha quietly as it got ready for more people to use it more heavily once the fall semester begins in the US.

Wolfram Alpha, the 'computational knowledge engine' from the makers of Mathematica, received its first major update today. According to Wolfram, this is the first broad update to the core code and data of Alpha since its launch, and includes a number of refinements to the way Alpha handles certain types of data and queries. Specifically, these refinements include combined time series plots of different quantities ("germany gdp vs population"), additional linguistic forms of many types of data and questions, and a number of updates to Alpha's data set, so that it now knows more about planets, foods, and government positions, for example. In total, the team touched about 1.1 million data values in this update and made 1,850 code commits.

Wolfram Alpha, the new "computational knowledge engine" from the makers of Mathematica is scheduled to officially launch on Monday next week, but starting tonight, Alpha will 'soft launch,' starting with a live webcast of the launch preparations tonight. After that, Alpha will gradually open its doors to everybody throughout the weekend. We have had a chance to test a preview version of Alpha for the last seven days, and we are quite impressed with what we have seen so far. Here are some resources for getting up to speed with Alpha, as well as some recommendations for getting started with this powerful, but sometimes frustrating new tool.
