Considering relabeling as 'pairwise interacts with'

Note that this relationship type, and sub-relationship types may be redundant with process terms from other ontologies. For example, the symbiotic relationship hierarchy parallels GO. The relations are provided as a convenient shortcut. Consider using the more expressive processual form to capture your data. In the future, these relations will be linked to their cognate processes through rules.
