1. A system for processing information, comprising:

  • a computer for running software programs in a distributed network, said computer including a processing means in communication with said distributed network;

    at least one storage means in communication with said processing means for storing programs and information; and

    at least one data agent in said distributed network for conducting a specific response to commands generated by said processing means;

    wherein said computer, said at least one storage means, and said at least one data agent are operable for;

    learning associations of natural language artifacts in unstructured data sources, wherein said artifacts include at least one of words, phrases, subjects, predicates, modifiers, and other syntactic forms; and

    learning semantic and syntactic relationships in structured data sources, wherein said structured data sources are in conventional formats used by relational database systems;

    further wherein learned associations resulting from said learning associations of natural language artifacts are formed using grouping of one natural language artifact in an interaction window with another at least one natural language artifact in said interaction window, based on a criteria of shared features of one or more sets from said grouping constituting measurements from said data sources;

    further wherein said criteria of shared features are dynamically determined without the use of a priori classifications and using conditional probability constraints between sets of learned associations; and

    further wherein said grouping creates a network of conditional probabilities between all encountered natural language artifacts or a subset thereof, determined by consideration of conditional interaction probabilities based on a history of measurements from said data sources.
