Typical behaviour of semantic similarity measures. Semantic similarity vs. sequence similarity results using Resnik's measure with the BMA approach: A - using the LRBS sequence similarity metric; B - using the RRBS metric; in red - full dataset results (points) and modelling curve (line) composed of two additive normal cumulative distribution functions; in green - non-electronic dataset results (points) and modelling curve (line) composed of a single normal cumulative distribution function. The results for the full dataset show a bimodal-like behaviour: there is a second increase in semantic similarity after a first plateau has been reached, which is more pronounced in A, but also visible in B. This behaviour is absent in the non-electronic dataset.
