Systems and methods are disclosed for preprocessing caller-agent pairs in a contact routing center, along with an intelligent routing system. A method includes determining at least one agent data for each agent of a set of agents, determining at least one caller data for each caller of a set of callers, and determining a score for each possible caller-agent pair of the set of agents and the set of callers using the agent data and the caller data in a pattern matching algorithm. The scores for each possible caller-agent pair may then be stored, e.g., in a look-up table, for retrieval, where matching a caller of the set of callers to an agent of the set of agents is based on the previously determined or calculated scores. For example, the caller-agent pair having the best score of all potential caller-agent pairs may be connected.
