Abstract:
1. A method of indexing ontological subjects of at least one composition into at least one ontological subject index, said index may correspond to a map and/or a graph of ontological subjects derived from the composition, comprising: a. decomposing the at least one composition to at least one partition; b. extracting at least some of ontological subjects of said at least one composition; c. constructing one or more data arrays corresponding to at least one participation matrix representing participation of at least one of said extracted ontological subjects into one or more of said partitions by having a non-zero value in the corresponding entries of the participation matrix, wherein each row of the participation matrix is representative of one of said extracted ontological subjects and each column of the participation matrix is representative of said partitions or vice versa, d. constructing one or more data arrays, corresponding to at least one matrix representing co-occurrences of each two of desired some of said some of ontological subjects, in the at least one partition of the at least one composition, from the one or more data arrays corresponding to said at least one participations matrix, e. constructing the at least one ontological subject index from said one or more data arrays, corresponding to said at least one matrix representing co-occurrences of ontological subjects and/or to said at least one participation matrix, said index may correspond to a map and/or a graph configured to uniquely assign one or more of the ontological subjects in the map wherein each ontological subject is connected to at least one of, other than itself, said uniquely assigned ontological subjects; and f. processing and/or storing the data of the index onto one or more non-transitory computer readable storages.
