There are many entity-attribute tables on the Web that can be utilized for enriching the entities of knowledge bases (KBs). This requires the schema mapping (matching) between the Web tables and the huge KBs. Existing solutions on schema mapping are inadequate for mapping a Web table and a KB, because of many reasons such as (1) there are many duplicates of entities and their types in a KB; (2)...

This paper characterizes the requirements of geographic information systems (GIS) middleware and its components for dynamic registering and discovering of spatial services specifically for collaborative modeling in environmental planning. The paper explores the role of Web services with respect to implementation standard and protocols and identifies implementation features for exposing distribu...

Ontologies are developed to describe data semantics on the Semantic Web. Given the distributed nature and scale of the Semantic Web, a large number of ontologies with different terminologies and structures will be created to describe the same concepts and domains. Without semantic mapping, information fluidity within the Web could be blocked at the boundaries of these ontologies. Therefore, ont...

The web is one of the important sources of information for different data integration systems. Semantic web represents the knowledge in web through ontologies. When knowledge is to be shared across different sources, integration of ontologies is achieved by means of ontology mapping and merging. When the ontology evolves from one state to another the mapping becomes stale and the user may not r...

It is cost effective and environmentally rational to develop renewable energy source in sthe territories of decentralized supply, since it allows replacing diesel power generation. Yakutia has a high potential for the development solar 64 % its area zone supply. The features web mapping—interactivity, multiscale availability—are useful assessment big multi-temporal data on resources at regional...

Due to the widespread availability of web mapping services , Internet users can now contribute cartographic content and easily create, modify, and share geographic maps. Several web mapping services that are currently available enable users to geographically locate text, pictures, and movies on a map and then share them with family, friends, and other interested users. However, few services giv...

The geospatial domain is influenced by the Web developments; consequently, an increasing number of geospatial web services become available through Internet. A rich description of geospatial web services is required to resolve semantic heterogeneity and achieve semantic interoperability of geospatial web services. However, existing geospatial web services descriptions and semantic mapping appro...
