TLDR
This paper argues that, for capturing the mapping between different ontologies, the direct use of a DL, even a very expressive one, is not sufficient, and it is necessary to resort to more flexible mechanisms based on the notion of query.Abstract:
One of the basic problems in the development of techniques for the semantic web is the integration of ontologies. In this paper we deal with a situation where we have various local ontologies, developed independently from each other, and we are required to build an integrated, global ontology as a mean for extracting information from the local ones. In this context, the problem of how to specify the mapping between the global ontology and the local ontologies is a fundamental one, and its solution is essential for establishing an ontology of integration. Description Logics (DLs) are an ideal candidate to formalize ontologies, due to their ability to express complex relationships between concepts. We argue, however, that, for capturing the mapping between different ontologies, the direct use of a DL, even a very expressive one, is not sufficient, and it is necessary to resort to more flexible mechanisms based on the notion of query. Also, we elaborate on the observation that, in the semantic web, the case of mutually inconsistent local ontologies will be very common, and we present the basic ideas in order to extend the integration framework with suitable nonmonotonic features for dealing with this case.read more

Ontology mapping: the state of the art
TL;DR: Ontology mapping is seen as a solution provider in today's landscape of ontology research as mentioned in this paper and provides a common layer from which several ontologies could be accessed and hence could exchange information in semantically sound manners.

Learning to map between ontologies on the semantic web
TL;DR: Glue is described, a system that employs machine learning techniques to find semantic mappings between ontologies and is distinguished in that it works with a variety of well-defined similarity notions and that it efficiently incorporates multiple types of knowledge.

On the decidability of query containment under constraints
TL;DR: This work addresses query containment under constraints within a setting where constraints are specified in the form of special inclusion dependencies over complex expressions, built by using intersection and difference of relations, special forms of quantification, regular expressions over binary relations, and cardinality constraints.

On the relative expressiveness of description logics and predicate logics
TL;DR: It is shown that the descriptions built using the constructors usually considered in the DL literature are characterized exactly as the predicates definable by formulas in \ tL3, the subset of first-order predicate calculus with monadic and dyadic predicates which allows only three variable symbols.
The Information Manifold
TL;DR: The Information Manifold is described, a system for browsing and querying of multiple networked information sources that demonstrates the viability of knowledge representation technology for retrieval and organization of information from disparate information sources.
