At present, there are vast amounts of information and applications available in distributed environment with heterogeneous databases, how to find them is a crucial task. An ontology-driven approach is put forward to overcome semantic heterogeneity caused by synonyms and homonyms during keyword-based search in catalogues. An ontology has a key role to play in the development of a spatially aware search...
Spatial information integration implies the ability to access and utilize multi-source spatial information from network environment. Cloud technology provides all kinds of resources service as an approach for spatial information integration, but there are many problems should be noted and resolved. This paper focuses on spatial information integration in network environment. Spatial data heterogeneity...
This paper presents a regional citrus pest forecasting and decision-making system established on Internet supported by Ontology, Expert System (ES), and Geographic Information Systems (GIS). The system adopted ontology to represent knowledge. The terrain data, weather data and pests damage information were interpreted with and merged into ontology. The expert system made a prediction about pests occurrence...
We have to build different SDSS (Spatial Decision Support System) to support different geospatial decisions. Among these SDSS, GIS data and models are usually used repeatedly. Thus, in this paper, we propose a ontology-oriented geospatial decision support system for discovering, efficiently using, and automatically executing GIS data and analysis resource on Internet. By the ontology-based system,...
Matching algorithm for Place Names is one of the most important research topics in the construction of digital gazetteers. Taking account of the morphological characteristics of Chinese Place Names and ontology method, we first pretreat the Chinese Place Names to remove illegal characters, decompose the Chinese Place Names into special names and generic terms, and then use both the Levenshtein Distance(LD)...
Typhoon disaster is a complex system in which the environmental possibilities with hazard (EPH) and the bodies bearing disasters (BBD) are various. And different disasters caused by typhoon not only have their own laws of occurring, developing and turning into disasters, but also have explicit relationships among them. As a modeling tool describing concepts on semantic and knowledge level, ontology...
Geographic information classification is one of the important topics in Geographical Ontology research. Based on the analysis of existing geographical ontological theory research and application research achievements, combining with the particularity of geographic object, this paper has made in-depth research of geographic information classification theory by using ontology and spatial cognition theory...
Geo-ontology is a newly risen research field in geospatial science. It was regarded as one of the most important research area in geospatial information science and digital earth. As the formal representation of geography cognition model or geography conceptual model, geo-ontology can support the description of geography concepts and semantic relationship of concept system well. Getting started with...
Integration and sharing of multiple heterogeneous geographic information and data sources are important for spatial analysis and decision making. However, the sharing and exchange of the geographic information are difficult because of semantic and schema heterogeneity of geographic information in different data sources. This paper presents an intelligent information sharing method of heterogeneous...
In this paper, we study the methods of constructing place-name ontology of Beijing based on attribute properties and spatial relation properties of place-name entities from the perspective of spatial cognition. Firstly, we locate place-name entities in the coordinate frame of Beijing city qualitatively and define the concept of place-name entities combining with the types of them. And then select...
Kanazawa is a historical city with famous traditional architecture, temples and merchant areas etc. The amount of places in these areas is large and each place has their own characteristic, different relations also exist among different places. But these figures and relations are not systematized to become a set of knowledge. This study aims to propose a prototype of personalized route planning system...
Based on the analysis of the existing problems in pixel-based image processing and object based image analysis (OBIA), this paper proposed a Geographic Unit Sequences (GUS) based image analysis approach, designed to apply geographic ontology knowledge to object based image analysis, so that the image analysis results become the carriers of geographic principle rather than the distribution of land...
Location is becoming kind of context fundamental information in ubiquitous computing environment. Location aware applications require a well-formed location model. Current location models can be classified into geometric location models and semantic location models. The former only represents the geometric coordinates without the location semantics. The later represents logical features and their...
In order to solve the existent problem of complexity of classification standard and inconstancy of combining geomorphologic factors in geomorphologic classification system, a Geomor-Onto(geomorphology ontology) is built up to describe complicated geomorphy classification problem. With the formal analysis to the semanteme of geomorphic conception, this paper proposes a logic structure of Geomor-Onto...
Spatial statistic data is location related data which could be visualized on a map that forms a thematic map. Nowadays, more and more spatial related data could be reached through internet as the development of geospatial data sharing. Traditionally, cartography of these data is done by experts manually; however, automatic cartography of the spatial statistic data could be of value to the users in...
A design method for integrated modeling and assessment DSS in Hydroinformatics based on ontology and domain modeling is given. Four levels of design are discussed. First, formal concept analysis is employed for domain ontology analysis and construction in Hydroinformatics. Second, OWL is used as representation language for domain ontology. In third level, metamodel method of domain model is combined...
