Abstract

This paper presents a report processing method with object-centered semantics. The syntactic analysis is performed along classical generative principles, though with a deliberately simple output as a list of index-value doublets, which the semantic module processes using methods in an object-oriented framework. The final representation is made of two types of object-centered structures: first, case like, event level dated structures corresponding to the input clauses: second, detailed representation of the current state of an agent of the reference world, plus records for the follow-up of a task over time. Uncertainty, imprecision and prevision are handled using specialized fields. This framework is applied to the processing of daily naval reports in English.
