1. A medical computer-based cognitive inference engine comprising:

  • an inquiry interface configured to receive an inquiry over a network;

    a medical knowledge database configured to store medical data objects, wherein each one of the medical data objects has data object attributes; and

    at least one server coupled with the inquiry interface and that is, upon execution of software instructions stored in a non-transitory computer readable memory by at least one processor, configurable to;

    receive, via the inquiry interface, the inquiry, wherein the inquiry relates to at least one patient;

    search the medical knowledge database to satisfy at least a portion of the inquiry, wherein the search identifies medical data objects related to the inquiry;

    select one or more reasoning rules sets from a plurality of reasoning rules sets as a function of data object attributes of the medical data objects related to the inquiry;

    generate a plurality of hypotheses comprising at least one of a recommended change to a treatment protocol or a likely response to a treatment protocol for the at least one patient by (1) applying the one or more reasoning rule sets to the data object attributes of the medical data objects related to the inquiry, and (2) determining correlations among the medical data objects related to the inquiry, wherein applying the one or more reasoning rule sets comprises mapping the data object attributes to a namespace related to known medical concepts, and weighting the mapped data object attributes based on medical reasoning criteria;

    assign merit scores for the plurality of hypotheses that account for one or more aspects of the data object attributes related to the inquiry and the one or more reasoning rule sets, wherein each merit score comprises a measure of validity of a hypothesis of the plurality of hypotheses; and

    rank at least some of the plurality of hypotheses by comparing at least some of the merit scores, wherein the at least some of the plurality of hypotheses are configured to be presented on a display of a computing device according to the ranking.
