A Conceptual Design Towards Semantic Geospatial Data Access
نویسندگان
چکیده
This paper presents a conceptual design for connecting ontological and geospatial knowledge bases so that the system can take advantage of the semantic power of ontologies and data storage/analysis/query power of geospatial systems. The design is based on common-place queries, such as “what is a canyon/route/road” or “where is the canyon/route/road X.”

Towards constructing an Integrative, Multi-Level Model for Cognition: The Function of Semantic Networks
Integrated approaches try to connect different constructs in different theories and reinterpret them using a common conceptual framework. In this research, using the concept of processing levels, an integrated, three-level model of the cognitive systems has been proposed and evaluated. Processing levels are divided into three categories of Feature-Oriented, Semantic and Conceptual Level based o...
متن کاملReal Time Semantic Interoperability in Ad Hoc Networks of Geospatial Data Sources: Challenges, Achievements and Perspectives
Recent advances in geospatial technologies have made available large amount of geospatial data. Meanwhile, new developments in Internet and communication technologies created a shift from isolated geospatial databases to ad hoc networks of geospatial data sources, where data sources can join or leave the network, and form groups to share data and services. However, effective integration and sha...
متن کاملA Conceptual Framework to Support Semantic Interoperability of Geospatial Datacubes
Today, we observe a wide use of geospatial databases that are implemented in many forms (e.g. transactional centralized systems, distributed databases, multidimensional datacubes). Among those possibilities, the multidimensional datacube is more appropriate to support interactive analysis and to guide the organization’s strategic decisions, especially when different epochs and levels of informa...
متن کاملDeriving Semantic Description Using Conceptual Schemas Embedded into a Geographic Context
Information integration and semantic heterogeneity are not trivial tasks. An integrated view must be able to describe various heterogeneous data sources and its interrelation to obtain shared conceptualizations. In this paper, we propose an approach to make a conceptualization of the real world based on conceptual schemas, which are used to generate a semantic description of the geospatial doma...
