A Topology-Based Metric for Measuring Term Similarity in the Gene Ontology

Table 4

Comparison of performance of our approach with Wang et al., Zhang et al. and annotation-based ones using Pearson’s correlation with enzyme Commission (eC), Pfam and sequence similarity, and resolution. Results are obtained from the CESSM online tool. For each ontology, the top two best scores among 12 approaches are in bold.
