Abstract

Over the past few years, several alternative approaches have been suggested to represent the spatial knowledge that emerges from natural environments. This paper introduces a rule-based approach whose objective is to generate a spatial semantic network derived from several humans reporting a navigation process in a natural environment. Verbal descriptions are decomposed and characterized by a graph-based model where actions and landmarks are the main abstractions. A set of rules implemented as first order predicate calculus are identified and applied, and allow to merge the common knowledge inferred from route descriptions. A spatial semantic network is derived and provides a global and semantic view of the environment. The whole approach is illustrated by a case study and some preliminary experimental results.
