Semantic Web reasoning systems are confronted with the task to process growing amounts of distributed, dynamic resources. This thesis presents a novel way of approaching the challenge by RDF graph traversal, exploiting the advantages of swarm intelligence. The nature-inspired and index-free methodology is realised by self-organising swarms of autonomous, light-weight entities that traverse RDF ...
