Computerized analysis of a concept map (CM) syntactic and semantic characteristics can become a complex task, whose results can be doubtful if the map contains either graphical or textual ambiguities. In the specific case of using CMs in education, the use of the results of automatic structural analysis of a map in learning assessment implies the existence of entirely computable maps, capable of coping with the inherently ambiguous nature of the language used in their construction, which results in imprecise concepts and linking phrases. This imprecision hinders initiatives toward computer processing of CMs. In this paper, we present a strategy to minimize the imprecision of linking phrases, by analyzing the nature of inclusivity in hierarchies of concepts in CMs. We present a formal extensible notation capable of distinguishing among the subtleties of these hierarchies. Based on this formalization, it is possible not only to determine precisely the dimension of inclusivity specified in a proposition, but also to define methods capable of determining the semantic distance between propositions in CMs.
