This abstract includes examples of each of the five bio-entities that PubTator identifies. Note the correct identification of mentions to non-small cell lung cancer regardless of whether the text uses the full term or its abbreviation, NSCLC. Likewise, PubTator correctly interprets the term “patients” as a reference to a species, Homo sapiens. Although this abstract uses protein-level nomenclature to describe gene variants (e.g. “XRCC1 Arg399Gln”), the authors distinguish genotypes with nucleotides rather than amino acids (e.g. “the XRCC1 399A/A genotype”). This variability is an example of the challenges inherent to named entity recognition of gene mutations.
