Chris Robison

If you're interested in a bit of detail on how the tech works, RuleSpace's Chris Robison used the phrase "proximity mapping" - word-pattern recognition based on words' locations relative to each other - in describing to us how the technology recognizes words in context.It "learns" how to recognize these patterns by being fed "very large samples of representative content - for example, porn," Chris said.After being given a lot of these samples the technology starts to "boil them down" to a "category model" that has unique features and patterns the technology can instantly identify.The tech also uses a sample of "what we call 'anti-content' - things that are absolutely not porn, for example, 'chicken breasts'," he added.

Probably the best technological solution to a problem like Candy's - proposed by Chris Robison, a tech expert at RuleSpace (the company behind AOL's filtering services) - is to install a personal "firewall" - software often used by families with fast (DSL or cable modem) connections to the Internet to block or control Net-wide access to their home PCs.
