% 0.18/0.38 % Comments : This is a simple test problem for reasoning in/about SUMO.
% 0.18/0.38 % Initally the problem has been hand generated in KIF syntax in
% 0.18/0.38 % SigmaKEE and then automatically translated by Benzmueller's
% 0.18/0.38 % KIF2TH0 translator into THF syntax.
% 0.18/0.38 % : The translation has been applied in two modes: local and SInE.
% 0.18/0.38 % The local mode only translates the local assumptions and the
% 0.18/0.38 % query. The SInE mode additionally translates the SInE-extract
% 0.18/0.38 % of the loaded knowledge base (usually SUMO).
% 0.18/0.38 % : The examples are selected to illustrate the benefits of
% 0.18/0.38 % higher-order reasoning in ontology reasoning.
