Complex arithmetic computations, especially if derived from bit-level software descriptions, can be very inefficient if implemented directly in hardware (e.g., by translation of t...
Answering queries over ontologies is an important issue for the Semantic Web. Aggregate queries were widely studied for relational databases but almost no results are known for ag...

Large scale ontology applications require efficient and robust description logic (DL) reasoning services. Expressive DLs usually have very high worst case complexity while tractab...
Reasoning capability is of crucial importance to many applications developed for the Semantic Web. Description Logics provide sound and complete reasoning algorithms that can effe...
This paper presents a three-step approach for interoperabilising heterogeneous semantic resources. Firstly, we construct homogeneous representations of these resources in a pivot ...
