Semantic Data Management (Dagstuhl Seminar 12171)

Abstract

This report documents the program and the outcomes of Dagstuhl Seminar 12171 "Semantic Data Management". The purpose of the seminar was to have a fruitful exchange of ideas between the semantic web, database systems and information retrieval communities, organised across four main themes: scalability, provenance, dynamicity and search. Relevant key questions cutting across all of these themes were: (i) how can existing DB and IR solutions be adapted to manage semantic data; and (ii) are there new challenges that arise for the DB and IR communities (i.e. are radically new techniques required)? The outcome was a deeper, more integrated understanding of the current state of the art on semantic data management and a the identification of a set of open challenges that will inform the three communities in this intersection.

Evolution of Ontologies using ASP

Abstract

RDF/S ontologies are often used in e-science to express domain knowledge regarding the respective field of investigation (e.g., cultural informatics, bioinformatics etc). Such ontologies need to change often to reflect the latest scientific understanding on the domain at hand, and are usually associated with constraints expressed using various declarative formalisms to express domain-specific requirements, such as cardinality or acyclicity constraints. Addressing the evolution of ontologies in the presence of ontological constraints imposes extra difficulties, because it forces us to respect the associated constraints during evolution. While these issues were addressed in previous work, this is the first work to examine how ASP techniques can be applied to model and implement the evolution process. ASP was chosen for its advantages in terms of a principled, rather than ad hoc implementation, its modularity and flexibility, and for being a state-of-the-art technique to tackle hard combinatorial problems. In particular, our approach consists in providing a general translation of the problem into ASP, thereby reducing it to an instance of an ASP program that can be solved by an ASP solver. Our experiments are promising, even for large ontologies, and also show that the scalability of the approach depends on the morphology of the input.
