Spatio-Temporal Reasoning and Query of Agricultural Geographic Information Based on Geo-Ontology and SWRL

摘要

This paper brings forth building spatio-temporal reasoning architecture and spatio-temporal query system based on adopting geo-ontology to represent spatio-temporal information knowledge and employing SWRL rules to express spatio-temporal reasoning rules. When carrying through spatiotemporal reasoning this paper adopts Jess to be a reasoner, which is the core of the whole architecture. Before carrying through reasoning this paper transforms geo-ontology and SWRL rules into fact base and rule base of Jess. After carrying through reasoning this paper uses obtained new facts to update original geo-ontology. In spatio-temporal query system this paper adopts input interface employing geo-ontology to conduct query requirement, and divides spatio-temporal query into three levels such as ordinary spatio-temporal query, simple spatio-temporal query based on semantics and complicated spatio-temporal query based on semantics. Under the background of experiment system of digital tobacco 3S, this paper develops spatio-temporal query architecture of agricultural geographic information based on geo-ontology and SWRL spatio-temporal reasoning rules. Through comparing and analyzing experiment result, this paper points out that spatio-temporal reasoning and spatio-temporal query based on geo-ontology and SWRL rules are future development orientation of spatio-temporal query of agricultural geographical information. The experiment case can provide powerful support for decision-making and management of planting tobacco.
