19. The computer implemented method of claim 12 , further comprising a graphical user interface that a user can point and/or interact and/or select the graphical objects and/or the links between the graphical objects.
12. A computer implemented method, comprising an implementation using a portion or whole capacity of one or more non-transitory computer readable media with a set of instructions thereon, executable by one or more processing devices, configured, while being or is executed, for representing a context for a body of knowledge by at least one graph comprising: accessing or building a first one or more data structures corresponding to at least one participation matrix representing participation of ontological subjects of a first predefined order into partitions or ontological subjects of a second predefined order of said body of knowledge; accessing, or building in real time, a second one or more data structures corresponding to association strengths between a plurality of ontological subjects of a predefined order; wherein said association strength is a function of: i. probability of occurrences of some of the ontological subjects of the first order in partitions or ontological subjects of a predefined order of the body of knowledge, and ii. co-occurrences of some ontological subjects of the first order in some of partitions or ontological subjects of a predefined order; accessing evaluated, or evaluating in real time, value significances for one or more partitions or one or more ontological subjects of the body of knowledge, based on data of one or more of said first and second one or more data structures and in respect to at least one significance aspect of the one or more partitions or one or more ontological subjects of the body of knowledge; identifying, using one or more data processing or computing devices, a plurality of ontological subjects of the body of knowledge based on their significance values and/or the association strength between at least two of the ontological subjects of the body of knowledge, and representing the identified ontological subjects graphically, by graphical objects and/or symbols and/or connecting at least two of the associated ontological subjects with graphical links based on their association strength to each other.
