Systems and methods are provided for receiving an input comprising one or more attributes, selecting a subset of query options from a list of query options relevant to the attributes of the input, and based on query optimization results from an audit of previous queries, determining a priority order to execute each query in the set of queries based on the query optimization results, and executing each query in the priority order to generate a candidate list. For each candidate in the list of candidates, systems and methods are provided for selecting a subset of available workflows based on relevance to the candidate and based on workflow optimization results, determining an order in which the selected subset of workflows is to be executed, and executing the selected subset of workflows in the determined order to generate a match score indicating the probability that the candidate matches the input.
