1. A computer implemented method of constructing at least one ontological subject map from a composition of ontological subjects, describing a universe, comprising: one or more computing devices, processing the composition comprising: selecting a plurality of ontological subjects participated in the composition; partitioning the composition to a plurality of partitions; constructing one or more data structures corresponding to at least one co-occurrence matrix with entries showing the co-occurrences of a number of said ontological subjects with each other in a desired number of partitions of the composition wherein the rows and columns of the co-occurrence matrix are indicative of ontological subjects, wherein an entry of the co-occurrence does not depend on linguistics semantic relations of the ontological subjects of the composition; constructing one or more data structures corresponding to at least one association matrix, using the data of the entries of said at least one co-occurrence matrix wherein entries of a row or a column of the association matrix are indicative of association values between an ontological subjects and one or more ontological subjects of the composition, the one or more computing devices, further processing the at least one association matrix according to predefined rules to attain data corresponding to at least one adjacency matrix of the at least one ontological subject map representable by nodes and connections wherein the nodes are indicative of the ontological subjects and the connections indicate associations between the connected nodes, wherein the ontological subjects are mapped over a multilayer map and said adjacency matrix configured to indicate the connections of desired number of ontological subjects in the map and wherein each of the desired number of ontological subject is connected to at least one growing node in the map, wherein said growing node have connection to at least another node in a layer below itself; and storing at least some of data, corresponding to at least one of the co-occurrence matrix or the association matrix or the adjacency matrix or the map, embedded in one or more data structures with predefined formats, into one or more non-transitory computer readable media.
