Nineteen teams presented results for the Gene Mention Task at the BioCreative II Workshop. 
In this task participants designed systems to identify substrings in sentences corresponding to gene name mentions. 
A variety of different methods were used and the results varied with a highest achieved F1 score of 0.8721. 
Here we present brief descriptions of all the methods used and a statistical analysis of the results. 
We also demonstrate that, by combining the results from all submissions, an F score of 0.9066 is feasible, 
and furthermore that the best result makes use of the lowest scoring submissions.
