Our procedure for deriving semantic representations is based on the hypothesis that if U contains named-entities that realize the distinguished attributes, that R will include the relevant relation in the domain ontology.
there is a trend for mappings to be rated higher for the food attribute (df=1, F=3.14, p=0.08) and the value attribute (df=1, F=3.55, p=0.06) for consistency, suggesting that perhaps it is easier to learn some mappings than others.
