“…Abdelmoty, Smart et al [1] propose the use of two frameworks, plus OWL, to build and maintain ontologies of places. Huang e Deng [18] propose the use of SWRL to Express spatiotemporal rules and to build geo-ontologies. GeoNet, created by Lopez-Pellicer, Silva et al [24] is implemented in RDF and comprises a set of classes and their properties, specified using WKT (Well-Known Text), GML (Geography Markup Language), and other geospatial standards.…”

The volume of spatial information on the Web grows daily, both in the form of online maps and as references to places embedded in documents and pages. Considering the spatial information needs of users, it is often necessary to recognize, within a document's text, the places to which it refers. This article presents a next-generation gazetteer, a toponymic dictionary which expands from the traditional cataloguing of place names and includes geographic elements such as spatial relationships, concepts and terms related to places. As such, we call it an OntoGazetteer, i.e., a gazetteer which also records semantic connections among places. The ontological gazetteer provides factual A previous version of this paper appeared at GEOINFO 2010, the Brazilian Symposium on Geoinformatics. and semantic support to solving several common problems in geographic information retrieval. This paper presents the OntoGazetteer and demonstrates its applicability to a place name disambiguation problem. Along with other problem solutions to which the OntoGazetteer can contribute, we present a case study on recognizing and disambiguating place names within news sources.

“…The client includes input interface of query requirements and output interface of query results, and users can input query conditions and and get query results through them. The core of framework is placed in the server, in which there are such 3 layers as interface layer, data layer and reasoning layer [9]. The spatio-temporal query of agricultural geographic information includes such 3 methods as ordinary query of agricultural geographic information(called OQAGI for short), simple query of agricultural geographic information based on semantics(called SQAGIBS for short) and complicated query of agricultural geographic information based on semantics(called CQAGIBS for short).…”

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.

In future, GIS will develop in the direction of popular application. Geography information sharing has become a stringent problem needed to resolve. Because people's cognition of real geographic world is different from each other, semantic discrepancy comes into being. As a result, Realization of geography information sharing has firstly to realize GIS's semantic sharing. Geo-ontology provides generally accepted concepts in geographic information domain and explicit formalized definitions thereof, so as to resolve the problem different geographic cognition gives rise to and inter-translation problem of description logic thereof. Geo-ontology can be applied to integration and sharing of geographic information. Start with the process of abstraction and generalization from real geographic world to computer world, this paper analyzes the source of semantic heterogeneity, and introduces geographic feature and its representing generalized geographic objects. Then this paper analyzes relationships between geo-ontology and geographic feature in detail, finally lay emphasis upon research on how to use geo-ontology to represent geographic features.GIS is about to enter into a popular application stage, and geography information sharing has become a stringent problem needed to resolve.Geography information sharing is communication process among data-producer, system and user, thereinto involving not only data itself but also semantics of data. Semantics is the meaning of concepts of things in the real world data corresponding to, as well as relationships among those semantics, which is explanation and logic representation of data in a certain domain. Semantics expresses people's cognition of real world by abstract of cognition model or formalized definition of geographic concepts. Since different discipline has different cognition model with regard to the same real world, semantic heterogeneity comes about, which includes naming heterogeneity and cognition heterogeneity. GIS semantics sharing lays emphasis on the ability of dealing with semantics discrepancy. Semantics interoperation may make GIS semantics keep a certain accuracy, integrity and consistency in the conversion and application process, so as to realize GIS semantics sharing that is the most effective. Consequently it is realized that geographic information can be more effectively utilized. Geo-ontology provides accepted concepts in geographic information domain and gives explicit and formalized definition of them, in order to solve the problem different geographic cognition give rise to and the intertranslating problem of logic description, which is applied to integration and sharing of geographic information.Owing to the above reasons, we have to research the following problems: (1) Abstracting process from the real geographic world to the computer world, and analyzing the source of bringing about semantic heterogeneity. (2) How to adopt geographic feature integrating geometric attributes with non-geometric attributes to represent abstracted geographic objects...
