+ - Wikipedia Used for Artificial Intelligence

eldavojohn writes: "It may be no surprise but Wikipedia is now being used in the field of artificial intelligence. The applications for this may be endless. For instance, the front of spam fighting is a tough one and it looks as though researchers are now turning towards an ontology or taxonomy based solution to fight spammers. The concept is also on the forefront of artificial intelligence and progress towards an application passing the Turing Test and creating semantically aware applications. The article comments on uses of Wikipedia in this manner:
"... spam filters block all messages containing the word 'vitamin,' but fail to block messages containing the word 'B12.' If the program never saw 'B12' before, it's just a word without any meaning. But you would know it's a vitamin," Markovitch said. "With our methodology, however, the computer will use its Wikipedia-based knowledge base to infer that 'B12' is strongly associated with the concept of vitamins, and will correctly identify the message as spam," he added.

+ - scientific basis for race: genome Hamming distance

An anonymous reader writes: Physics professor describes how genetic clustering corresponds to racial identity. Individual genetic data, when plotted in an abstract genome space, tends to cluster into groups corresponding to traditional continental ethnic groups (Europeans, Africans, Asians, etc.). Race is more than a matter of pigmentation or other superficial traits: it determines the likelihood an individual is carrying a particular gene variant.
