Common Sense Computing Initiative

When people communicate, they rely on a large body of shared common sense knowledge in order to understand each other. Many barriers we face today in artificial intelligence and user interface design are due to the fact that computers do not share this knowledge. To improve computers’ understanding of the world that people live in and talk about, we need to provide them with usable knowledge about the basic relationships between things that nearly every person knows.In 1999, we began a project at the MIT Media Lab to collect common sense from volunteers on the internet. Ten years later our project has expanded to encompass many different areas, languages, and problems. Currently, the English site has over a million sentences from over 15,000 contributors.

Open source search engines every developer should know about.

Search is a crucial feature of any website.  Even if your navigation is crystal clear, it still doesn’t cater for those power users and return visitors that remembered a particular piece of content, or want to find collections of information stored on your site in the same topical areas.

Typically search is one of the most poorly implemented pieces of technology on a site, with developers opting for the standard the out of the box solution which comes with most modern content management systems – and in many cases doesn’t do justice to your content. I thought I’d take a look at what other enterprise level and open source search engines out there to find and index the information on your site faster, and provide users with a deeper, more relevant resultset.
