<strong>Practical Pattern Matching</strong><div>Danna Voth</div><p>Humans are fascinated by patterns, and they can spot them well?in fact, that?s one area where humans excel over computers. But research is producing interesting competition as scientists discover and employ new methods of automated pattern recognition. Practical applications include finding genes, detecting cancer-causing chemicals in molecules, searching out potential terrorists, and predicting terrorist threat levels, as well as recognizing speech patterns and creating a nanotechnology resource library.</p><p><strong>"Sassy" Chatbot Wins with Wit</strong><div>Benjamin Alfonsi</div><p>When you sit down for an online chat with computer scientist Rollo Carpenter, you're not quite sure if it's him on the other end or his virtual alter ego, a chatbot named George. And that, in a nutshell, is the point of Carpenter's research. In the 2005 Loebner Prize contest, a panel of judges found George to be the most convincing conversationalist of the four chatbot participants, which included reigning three-time champion Alice. The contest, launched in 1990 by Hugh Gene Loebner and touted as "the first formal instantiation of a Turing Test," gauges the contestants' "intelligence" levels.</p></p>
