GN system evaluation. Results from the GN system evaluation. (A) GN system performance (F-measure) as it relates to the combined gene tagger performance. (B) GN system performance based on each of the three methods for combining gene tagger output (Overlapping, Consensus, Consensus followed by Overlapping). (C) GN System performance highlighting the combination of the overlapping filter with and without use of the dictionary-based GM system. Data points generated using the other filters are shown in gray. (D) Same as C, with the presence/absence of another representative tagger shown. (E) and (F): GN system performance as it relates to combined gene tagger precision and recall, respectively.
