SEMANTIC ANALYSIS OF ECONOMIC SURVEYS
Jean-Christophe Planes, Philippe Trigano · Applied Artificial Intelligence · 1993
This paper presents the principles of the semantic analysis used in a system for the summary of economic surveys. We will focus on the conceptual representation that is based on semantic primitives. Because of the different relations (casual or structural links) between concepts, this model is powerful in the representation of language structural properties. Besides, the summary goal allows a proper definition of significant features necessary for the elaboration of a taxonomy. The requested adaptability to various and overlapping economic domains induces a hierarcfucal organization of primitives sets. The notion of reference then allows the definition of contextual links between concepts. The analysis is composed of two phases. The first one is syntactico-semantic and builds a conceptual representation of the sentence content according to the conceptual graphs formalism. The second one, essentially pragmatic, removes the paraphrastic structures that would not be detected by the syntactico-semantic phase and leads to a synthesis network.
