1. A computer-implemented system for storing and retrieving knowledge, comprising:

  • a processor executing a sequence of instructions, and a memory, the sequence of instructions defining;

    a text analyzer having an input which receives a signal representing information expressed as natural language and which produces at an output a signal representing annotated information;

    a parser having an input which receives the annotated information signal from the text analyzer and which produces and stores in the memory a linked knowledge model thereof; and

    a user interface presenting at least one pair of complementary relationships to an operator, through which the operator can navigate the linked knowledge model to retrieve knowledge;

    wherein the linked knowledge model includes a first node defining a first task and a second node defining a second task, each stored in the memory, the first node and the second node forward and backward linked to each other, the first task defining why the second task is performed and the second task defining how the first task is performed.
