Claim One:
1. A method of characterizing biological material in a sample containing genetic material from a plurality of organisms, the method comprising: (a) creating, using a processor having a memory, a reference word table for a plurality of genome reads from a reference database containing genomic identities of organisms comprising: (a1) splitting each of the genome reads into reference words, (a2) creating a list of reference words from the reference words for each of the genome reads, and (a3) storing the lists of reference words in a reference word table in a memory; (b) creating, using a processor having a memory, a list of sample sequence words for each of a plurality of unassembled metagenomic fragment reads generated by sequencing metagenomic fragments extracted from a sample, the creating comprising: (b1) splitting each of the unassembled metagenomic fragment reads into sample sequence words, and (b2) creating a list of sample sequence words from the sample sequence words for each of the unassembled metagenomic fragments; (c) performing, using a processor having a memory, probabilistic methods that compare the sample sequence words in the lists of sample sequence words with the reference words in the lists of references words stored in the reference word table and produce probabilistic results; and (d) determining, using a processor having a memory, the identities of organisms contained in the sample at least to the species level using the probabilistic results.
