BANNER is released under the Common Public License 1.0 and can be tested online or downloaded from the releases page, though the CVS repository contains more recent updates. BANNER is constantly being improved, so you may wish to subscribe to the updates mailing list to be notified of new releases and bug fixes.
BANNER was written and is maintained by Bob Leaman and is advised by Dr. Graciela Gonzalez, both members of the BioAI lab at Arizona State University.
We have compared BANNER to the official results of the Second BioCreative Challenge Evaluation. Following the protocol for the BioCreative 2 gene mention task, BANNER was trained for this evaluation on the entire BioCreative 2 gene mention task training set and tested on the test set, both of which can be downloaded from the BioCreative 2 datasets. A difference of 1.23 or more f-measure is statistically significant, a difference of 0.35 or less is not (p < 0.05). Both the version of BANNER as published and the current version of BANNER, which includes a dictionary feature and is available in the CVS repository, are listed.
|System or author||Rank at BioCreative 2||Precision (%)||Recall (%)||F-Measure|
|BANNER (as published)||-||87.18||82.78||84.92|
|Baumgartner et. al.||11 (median)||85.54||76.83||80.95|
We have also compared BANNER to ABNER and LingPipe (existing freely-available software), on two different corpora, using 5x2 cross-validation.
