“…There has been much research in the area of graphical mapping tools, e.g. [9,10], however we believe there are many challenges still to be addressed. In particular, our focus has been on defining strategies that hide the burden of logical languages, that are generally used to express ontology alignments, from the domain expert.…”

“…The benefits of using ontologies, especially in heterogenous environments where more than one ontology is used, can only be realized if this process is effective. The trend is to provide graphical tools capable of creating alignments during design-time in a (semi-)automatic manner [2,10,9]. These alignments consist of mapping rules, frequently described as statements in a logical language.…”

Abstract. In a semantic environment data is described by ontologies and heterogeneity problems have to be solved at the ontological level. This means that alignments between ontologies have to be created, most probably during design-time, and used in various run-time processes. Such alignments describe a set of mappings between the source and target ontologies, where the mappings show how instance data from one ontology can be expressed in terms of another ontology. We propose a formal model for mapping creation. Starting from this model we explore how such a model maps onto a design-time graphical tool that can be used in creating alignments between ontologies. We also investigate how such a model helps in expressing the mappings in a logical language, based on the semantic relationships identified using the graphical tool.

Ontology mapping is the process whereby semantic relations are defined between two ontologies at conceptual level, which in turn are applied at data level transforming source ontology instances into target ontology instances. This paper focuses on the formalisation, representation and automatic specification of semantic relations between two ontologies. The described approach grounds on the notion of service, which represents not only the transformation capabilities of the system, but also the expertise in the manipulation of semantic relations. The main contributions of this paper are the formalisation of the ontology mapping process and the specification of the multidimensional service-oriented architecture.

“…The work presented in [29] provides an encoding of the extensible knowledge on commonly found semantic conflicts, providing an automatic way of comparing and manipulating contextual knowledge of different information sources, which is used for semantic transformation across heterogeneous databases. In [33], the MAFRA Toolkit is presented, the tool helps a domain expert to work on ontology mapping tasks. Whereas these previous approaches are concerned with the specification of semantic conflicts that arise between different sources, ours is concerned with the particular problem of identifying pairs of corresponding terms in different ontologies.…”

Abstract. This paper proposes a cooperative approach for composite ontology mapping. We first present an extended classification of automated ontology matching and propose an automatic composite solution for the matching problem based on cooperation. In our proposal, agents apply individual mapping algorithms and cooperate in order to change their individual results. We assume that the approaches are complementary to each other and their combination produces better results than the individual ones. Next, we compare our model with three state of the art matching systems. The results are promising specially for what concerns precision and recall. Finally, we propose an argumentation formalism as an extension of our initial model. We compare our argumentation model with the matching systems, showing improvements on the results.
