A computerized system and method of compressing symbolic information organized into a plurality of documents, each document having a plurality of symbols, the system and method including: (i) automatically identifying a plurality of sequential (also referred to as adjacent) and/or non-sequential symbol (also referred to as non-adjacent) pairs in an input document; (ii) counting the number of appearances of each unique symbol pair; and (iii) producing a compressed document that includes a replacement symbol at each position associated with one of the plurality of symbol pairs, at least one of which corresponds to a non-sequential symbol pair. For each non-sequential pair the compressed document includes corresponding indicia indicating a distance between locations of the non-sequential symbols of the pair in the input document.
