That's the AI part of the article. Basically, the LHC spits out data so your your Big Data looks small. The first pass was for data confirming/disconfirming some big theories where a specific peek at the data would give meaningful answers. So far the data shows that we had it right to start with. Now, for the next pass, they're expanding how they look at the data to find anything 'unusual'. "Pattern recognition" in this case is a bit harder than just checking for a recurring value, or a "true" in the "Unified theory of everything?" field. We're a bit closer to what we would generally call AI, and at very least some interesting techniques with more interesting followup experiments to weed out false positives.
