Abstract

We present an initial ontology for tactical behaviors conducted by unmanned ground vehicles (UGVs). We focus on activities, which are the denotations of verbs, notably 'move' but also 'look (for)' and several others. These take collective subjects, allowing activities to be attributed to units at various hierarchical levels. The semantics of verbs must consider the denotations of their grammatical complements; that is, we must consider entire verb frames. The thematic relations of the noun-phrase complements are critical, but prepositions also play an important role. FrameNet is an online lexical database of frames derived from text corpora. Our other major resource is Levin's classification of verbs according to how changes in their frames affect their meanings. Although natural languages have a large variety of words for aspects of tactical behaviors, there is motivation to get by with as few basic verbs as possible. A variety of meanings can often be associated with a verb by altering its frame, and we can impose co-reference constraints on combinations of frames to generate structures denoting more complex activities. A simple grammar is developed for the verbs of interest. Protege-Frames ontologies include classes that inherit from linguistically inspired classes but capture domain-specific notions.
