Abstract Qualitative Spatial Reasoning (QSR) is a subfield of Artificial Intelligence that addresses the formal knowledge representation of spatial problems without relying on measures, coordinates, or numeric models, just on symbolic mapping of expressions and logic calculi, so it often relates to linguistic semantics and computational linguistics. This project presents a semantic-computational inquiry into spatiality in natural language utterances in order to put forth both descriptive and inferential models capable of rendering a qualitative calculus for the deictic perspective, which is one of the most commonly used perspective systems in conversational contexts. With a formal ontology of spatial objects embedded, this calculus should be easily integrated to Natural Language Inference algorithms. Theoretical foundations of spatial relations representations such as the figure / ground distinction and perspectives systems are discussed and a fragment of the deictic perspective calculus is introduced. | |
