The expert system is a small AI, designed to search computers for certain patterns. They are used to track people, find intruders or anything else in the area of pattern recognition. For example, if the user wants to know if someone is a mage. The expert system immediately begins to collect all available information, comparing it to known mages and making assumptions on its own. For example, if the person has been seen with known mages, has won on the lottery 100% more than average, has an almost perfect medical record and is known to be regarded as an eccentric, then the expert will inform the user that it is 88% chance for the person to have an awakened avatar, and 65% chance for him to be a true mage, given this information.
These Expert systems are constantly tracking certain people the technocracy have become interested in, noticing if something odd happens. They also search for intruders in their systems, nodes, breaches of the Gauntlet and general weirdness.
