The growth of regional trade blocks has been one of the major developments in international relations in recent years. Regional agreements vary widely but, all have the objective of reducing barriers to trade between member countries that in most cases result in increasingly trade flows and economic growth. This paper attempts to explore the results of trade integration in ECO, EU and OIC block...

The CyberWater project is created to develop an open data and model integration framework for studying complex environmental water problems, where diverse online sources can be directly accessed by models without any need of users’ extra effort on the tedious tasks preparation their models. We present our design development a novel generic agent toolkit in context CyberWater, which enables user...

In this paper we present the Data and Knowledge Model (DK-model) that integrates the representation of data and certain types of knowledge in a semantic data model. The ER model is used as a basis for the DK-model. The main features of the DK-model are modularity of modelling, generalization/spe-cialization hierarchies, deductive capabilities in the form of so-called virtual attributes, and inh...

In information ecosystems, semantic heterogeneity is known as the root issue for the difficulties of data integration, and the Relational Model is not designed for addressing such challenges, i.e. to re-use data that is modeled from other sources in the local data model design. Although researchers have proposed many different approaches, and software vendors have designed tools to help the dat...
