What word can I use for things with the same external appearance but with different inherent meanings.
For example, assume that in a social network, different users make friendships. All of the relations are thus friendship relations, a single type of relation. However, from an analytical viewpoint they may have different meanings/intents/... . For example, one may have been formed because the two persons are relative, another may have been formed because they are colleagues, and another may have been formed because one is interested in the posts the other person posts. These different meanings/intents/... may have different effects in some application.
Is modal a good word to be used in these examples: multi-modal relationships, modal-specific networks (a network in which all relations have a single meaning). What about modality? (e.g., multi-modality)
