The Semantic Web is the vision of a Web of data usable for both humans but also machines. This web, consists of inter-connected instance data annotated with possibly expressive ontologies. Therefore a tremendous amount of information becomes available that should be processed based on formal semantics attached to it. The Semantic Web community has developed a number of languages (such as RDF, RDF Schema, OWL) that deploy logic for this purpose. Impressive progress has been made on scalable storage, querying and inference for these languages, and they are successfully being deployed on large intranets and medium-scale web-applications.
However existing reasoning techniques often fail to live up to the expectations put into them in this context. They can often neither deal with high number of instances, the expressiveness of the ontologies describing them or the inherent inconsistency and incompleteness of data on the Web.
This special issue is intended to focus on these problems of scalability and robustness of reasoning on the Web, and furthermore to investigate alternative reasoning methods, which take incompleteness and distribution of data and knowledge as inherent properties into account.
