AWARE – DAG-transformations for Semantic Analysis
Aarno Lehtola, Timo Honkela · DSpace repository (University of Tartu) · 1988
AWARE is a knowledge representation language for specifying NLU inference rules.AWARE-system takes as its input the parse trees of NL utterances and further refines them by using DAG-transformations (Directed Acyclic Graph) and recursive descent translation techniques.AWARE has been used for semantic analysis in our Finnish language database interface.The input dependency tree is transformed first into a predication DAG and then reduced into a conceptual database query.
