Presently, a lot of Geographic Information Systems are operating all over the world, especially in administrations, and one of the problems is to make them cooperate, especially at the data level, such as an institution can profit from the data of another institution. This problem is identified as GIS interoperability since the idea is to share not only data but also programs and services. The ...

The petroleum industry is a technically challenging business with high investments, complex projects and operational structures. There are numerous companies and public offices involved in the exploitation of a new oil field, and there is a high degree of specialization among them. Even though standardization has been considered important in this industry for many years, there is still very lit...

This work presents ongoing research in Pan-European Public Services (PEPS) and Pan-European EGovernment Services (PEGS). This field of work is relatively new and has attracted the attention of the European Commission and of many research organizations and businesses as well. The semantic interoperability issues that may arise when a citizen of one Member State requests a public service from the...

The networked information environment comprising digital libraries, digital collections, and digital repositories increase people’s expectations for information access. Specifically, users anticipate better search capabilities across these networked information resources and the metadata records associated with the resources. The opportunities also exist for improved information exchange or int...

A fundamental premise of the semantic web is that a level of interoperability is guaranteed among applications running in an open environment. By the use of ontologies applications are able to share information and exchange meaningful data. In this context ontology alignment is paramount to assure communication among applications. In this paper we propose an ontology alignment strategy based in...

Semantic interoperability is a process to facilitate the reuse of geospatial data in a distributed and heterogeneous environment. In this process, the provided geospatial metadata that are appropriate for the intended use may be incomplete or not appropriate for data reuse. Thus, the external quality (fitness for use) of these metadata seems important for data reuse, since it has the potential ...

The problem of how to introduce meaning into computer systems so that these can have semantic interoperability; has been the main issue for the construction of Ontologies. Currently, procedures used for its Annotation is made by humans for building a Semantic Network and present conflicts on the consensus of concepts and their meanings. This paper presents and approach for the development of On...

Emergency response is a complex activity involving many actors and heterogeneous spatial data. Two of the major challenges are the integration and extraction of these data and their transmission to emergency management actors. Although significant progress has been made regarding the systemic and syntactic heterogeneity of data in this context, semantic heterogeneity remains insufficiently addr...

As an important data quality dimension, semantic interoperability of data can potentially be improved using data standards. Certain data standards are extensible, allowing users to introduce custom data elements. How interoperable is data created using an extensible data standard? How does extensibility of a data standard affect interoperability of data created using the standard? How does a st...

Interoperability (IOP) is considered a critical success factor to forge ahead in the online provi-sion of public services. Interoperability frameworks shall give guidance to practitioners what to consider and to do in order to enable seamless interaction with other public authorities and clients. The well known European Interoperability Framework (EIF) and many others are designed as multilayer...
