Twitter semantic analysis

Expert System, an italian technological firm that specializes in semantic web and natural language processing has released a tool that allows you to analyze your tweets and produce nice charts that depict the topics you tweet about. This tool functions thanks to their COGITO software that gets entities out of words. The same tool also powers ambitious project like OKKAM which aims to avoid the birth of different URI referring to the same entities.
