1. A system comprising:

  • a processor;

    a data bus coupled to the processor; and

    a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for;

    receiving data from a data source;

    processing the data, the processing comprising performing a parsing operation on the data, the processing the data identifying a plurality of knowledge elements based upon the parsing operation, the parsing operation comprising ranking of parse options, the processing being performed via a cognitive inference and learning system, the cognitive inference and learning system executing on a hardware processor of an information processing system and interacting with the plurality of data sources, the cognitive inference and learning system and the information processing system providing a cognitive computing function, the cognitive inference and learning system comprising a cognitive platform, the cognitive platform comprising a cognitive engine, the cognitive engine processing the data from the data source; and

    ,storing the knowledge elements within the cognitive graph of a universal knowledge repository as a collection of knowledge elements, the storing universally representing knowledge obtained from the data, the cognitive graph comprising integrated machine learning functionality, the integrated machine learning functionality using extracted features of newly-observed data from user feedback received during a learning phase to improve accuracy of knowledge stored within the cognitive graph;

    performing mapping operations on a query to generate query related knowledge elements based upon the user feedback, the mapping operations generating a set of parse trees using a parse rule set, the mapping operations comprising mapping structural elements to resolve ambiguity, the mapping operations comprising mapping structural elements of the query around a verb of the query, the mapping of the structural elements transforming the structural elements into words higher up an inheritance chain within the cognitive graph, the parse trees being ranked by a conceptualization ranking rule set, the parse trees representing ambiguous portions of the text of the query, the parse trees being used when performing the parsing operations;

    submitting an insight agent query from an insight agent to the universal knowledge repository; and

    ,providing matching results to the insight agent responsive to the insight agent query based upon a matching rule set and a plurality of answer related knowledge elements in the universal knowledge repository.
