Otto is our semi-automated beer-bot and he's quite clever. He compiles flavour profiles of each beer by pooling, cross-referencing and collating a number of data-sources: the brewer's description; beer festival tasting notes; quantitative data such as IBUs for bitterness and SRM/Lovibond and EBC to determine colour; other classification scheme descriptions; tasting notes from blogs and wikis and a wide range of other sources. He has an extensive vocabulary of beer-flavour descriptors that are mapped to each of the PintPicker flavour attributes on a quantitative scale. He ascribes each source a Trust Quotient (based on how closely that source's descriptions match his own) and applies a set of conflict resolution algorithms wherever he encounters inconsistent information (which is quite common in the brewing and beer-tasting world). He's remarkably accurate (check out his profiles on the site) and unlike us, he can sample loads of beers without falling over! He is a unique example of AI (ale intelligence). But he's not infallible, so all his reviews are thoroughly checked by a human before being uploaded to the site.
