[adapt def] semantic expressiveness

current definition: a quality which inheres in an entity by virtue of its ability to store and represent knowledge in a form accessible to human and/or machines.

From Discussion at sprint: Knowledge is not directly represented, but meaning is represented so that knowledge can be inferred. We suggest to change the definition:

A quality which inheres in an entity by virtue of its ability to represent meaning in a form that is accessible to humans and/or machines and allows knowledge inference.
