A Linguistic Foundation for Communicating Geo-Information in the context of BML and geoBML
Abstract
Battle Management Language (BML) is a formal language for military communication, i.e., exchanging orders and reports. Orders and reports refer to geo-information. In particular, orders use overlays to connect geo-information to task assignments. The problem studied by this project is how to formalize geo-information and overlays, and to connect this formalized information to BML orders and reports such that a system can process them coherently and operate on the processed orders and reports in the way intended. BML expressions can be generated by the Command and Control Lexical Grammar (C2LG) that is based on linguistic principles (i.e., lexicality, principle of coherence, principle of completeness). In the project, the grammar has been broadened. In addition, formal representations of tactical spatial objects and of overlays have been developed that, on the one hand, are XML representations and, on the other hand, can be connected to C2LG expressions, such that the expressions can be parsed to argument structures which include both the task assignment information and the corresponding geo-information. To preserve the linguistic principles, so-called overlay excerpts have been defined and developed. These excerpts ensure that only those parts of an overlay are connected to a task assignment which are of relevance for that assignment. The central elements of these overlay excerpts (and thus also the elements of the overlays) are formal representations of tactical spatial objects (mostly control features). These tactical spatial objects derive from the geoBML process. In order to make them processable in connection with formal orders and reports, the formal representation of the tactical spatial objects also has been structured in accordance with the linguistic principles and in accordance with doctrine.
