Schema mapping and data mapping have been two topics widely studied in traditional database related communities. Recently, with the rising interest in the semantical web, the tasks of integrating heterogeneous information sources, both in a schema and a data instance level, are becoming of more practical importance. Current efforts at resolving these two mapping tasks, namely, schema mapping an...

The Semantic Web is rapidly becoming a defacto distributed repository for semantically represented data, thus leveraging on the added on value of the network effect. Various ontology mapping techniques and tools have been devised to facilitate the bridging and integration of distributed data repositories. Nevertheless, ontology mapping can benefit from human supervision to increase accuracy of ...

Ontology mapping is the key to data interoperability in the semantic web. This problem has received a lot of research attention, however, the research emphasis has been mostly devoted to automating the mapping process, even though the creation of mappings often involve the user. As industry interest in semantic web technologies grows and the number of widely adopted semantic web applications in...

Our approach offers an alternative way for dynamic web-based mapping. An Internet file system can be accessible via web browsers in which users can upload, download, view, and execute files. Our system will allow users select shape files from the web interface of the Internet file system for mapping using the ArcIMS services. The integration of the ArcIMS with the Internet file system provides ...

In this paper, we describe a mapping language for converting data contained in arbitrary spreadsheets into the Web Ontology Language (OWL). The developed language overcomes shortcomings with existing spreadsheet mapping techniques, including their restriction to well-formed spreadsheets reminiscent of a single relational database table and verbose syntax for expressing mapping rules when transf...

AbstrAct The semantic Web suggests to annotate Web resources with machine-processable metadata; and on-tologies, as means to conceptualize and structure knowledge, are seen as the key to realize the vision of the semantic Web. However, ontologies themselves do not provide semantic interoperability, since a single ontology cannot be used to represent all kinds of domains and applications. Ontolo...

This paper introduces an approach to mapping relational database contents to ontologies. The current effort is motivated by the need of including into the Semantic Web volumes of web data not satisfied by current search engines. A graphical tool is developed in order to ease the mapping procedure and export enhanced ontologies linked to database entities. Moreover, queries using semantic web qu...

The main objective of this research was to develop a web-based geographic information system (GIS) based on detailed analysis user preferences from the perspective forest research, management and education. An anonymous questionnaire used elicit for hardware platform evaluations web-mapping applications, data, GIS tools. Mobile slightly more often than desktop GIS. Web-mapping applications that...
