Of the 216 abstracts, 122 were assigned to set A and 30 to set B by all curators, whereas for 64 there was disagreement. This spread of results underscores the importance of using several independent annotators in assessing the accuracy of a method: although the criteria for interesting vs. uninteresting abstracts may be relatively clear (as specified above), the interpretation of these criteria can vary considerably from annotator to annotator. Unlike the cell-cycle data, where the correct assessment of each abstract could be determined automatically, for the Arabidopsis data the 'correct' classification was considered to be that defined by the majority vote of the three independent assignments (i.e., 166 for set A and 50 for set B).
When using both sets A and B as input, Caipirini achieved 87% precision (i.e., found 188 correct assignments). Because set C is decomposed in two classes of very different sizes (dominated by set A-like abstracts), we also calculated the Matthew's correlation coefficient and found that Caipirini achieved a good prediction (with correlation equal to 0.6). Of the 24 false positives obtained, fourteen were already ambiguously categorized by manual examination (i.e., one out of the three annotators disagreed; but not the same curator every time), and of the four false negatives, two were also 'ambiguous' (i.e., one of the three annotators disagreed; the same one in both cases). When the curators later focused on the unambiguously annotated as false positive abstracts, they noted that some could be indeed considered as related to resistance, but 'indirectly' (Additional file 2). 2ff7e9595c
