Abstract

Spatial reasoning has gradually become a research hotspot in some domains such as GIS and spatio-temporal database. At present many spatio-temporal methods put forward by scholars are methods based on logic or algebra by and large, and researches on formalization representation and reasoning of geographic spatio-temporal knowledge are few. Geo-ontology researches detailed connotations and hierarchy relationships of concepts of geographic spatial information in the geoinformatics domain and offers semantic annotations of concepts. Semantic and spatio-temporal relationships can fuse into geo-ontology and form knowledge base of geo-ontology. But OWL, an ontology representation language, canpsilat describe determining and reasoning rules of spatio-temporal relationships owing on account of its limitation. At the same time SWRL can make up the deficiency of OWL, which implements the combination of Horn-like rules and OWL knowledge base by adopting highly abstract syntax to express knowledge represented by OWL ontology. This paper does a research on adopting geo-ontology to represent semantic and spatio-temporal relationships and applying SWRL to express spatio-temporal rules, which lays the solid foundation of spatio-temporal reasoning.

A framework is developed in which spatio-temporal predicates can be obtained by temporal aggregation of elementary spatial predicates and sequential composition, and two approaches are considered to consider possible transitions between spatial configurations.

The theory thus accounts for qualitative spatial information, dealing with underspecified, symbolic information when accurate data are not available or unnecessary, and gives a basis for commonsense spatio–temporal reasoning by presenting a number of significant deductions in the theory.

A new method which describes spatio-temporal relations between objects is described which is able to track the objects and therefore the relations between them online so that the authors are able to interpret situations over time during the game.
