Abstract

Querying and sharing Web proteomics data is not an easy task. Given that, several data sources can be used to answer the same sub-goals in the Global query, it is obvious that we can have many candidates rewritings. The user-query is formulated using Concepts and Properties related to Proteomics research (Domain Ontology). Semantic mappings describe the contents of underlying sources. In this paper, we propose a characterization of query rewriting problem using semantic mappings as an associated hypergraph. Hence, the generation of candidates’ rewritings can be formulated as the discovery of minimal Transversals of an hypergraph. We exploit and adapt algorithms available in Hypergraph Theory to find all candidates rewritings from a query answering problem. Then, in future work, some relevant criteria could help to determine optimal and qualitative rewritings, according to user needs, and sources performances.
