Table 6 Facets extraction evaluation

Facet	Concepts	Resources	Precision	Recall	F-measure
Input	259	399	0.69	0.93	0.73
Output	266	274	0.6	0.94	0.64
Method	136	210	0.44	0.53	0.35
Disease	142	144	-	-	-
Species	292	287	-	-	-

This table shows the number of concepts that our approach has automatically extracted for each facet and the number of resources that are annotated with those concepts. Moreover, for the input/output and method facets the precision, recall and F measures are shown. These measures have been calculated for the automatically extracted information with respect to the GS. The disease and species facets have not been evaluated because of their poor representation in the GS.
