  The corpus reported in this paper was developed for the evaluation of a
domain-specific Text to Knowledge Mapping (TKM) prototype. The TKM prototype
operates on the basis of both a combinatory categorical grammar (CCG)
linguistic model and a knowledge model that consists of three layers: ontology,
qualitative and quantitative layers. In the course of this evaluation it was
necessary to populate these initial models with lexical items and semantic
relations. Both elements, the lexicon and semantic relations, are meant to
reflect the domain of the prototype; hence both had to be extracted from the
corpus. While dealing with the lexicon was straight forward, the identification
and extraction of appropriate semantic relations was much more involved. It was
necessary, therefore, to manually develop a conceptual structure for the domain
which was then used to formulate a domain-specific framework of semantic
relations. The conceptual structure was developed using the Cmap tool of IHMC.
The framework of semantic relations- that has resulted from this study
consisted of 55 relations, out of which 42 have inverse relations.
