- 7 abstract "ABox abduction is the process of finding statements that should be added to an ontology to entail a specific conclusion. In this paper, we propose an approach for probabilistic abductive reasoning for SHIQ. Our evaluations show that the proposed approach significantly extends classical abduction by effectively and correctly estimating probabilities for abductive explanations. Lastly, based on the ideas proposed for SHIQ, we describe a tractable algorithm for probabilistic abduction in DL-lite_R.".

- 8 abstract "In the last years, reasoning over very large ontologies became more and more important. In our contribution, we propose a reasoning infrastructure, which can perform instance checking and instance retrieval over ontologies with semi-expressive terminological knowledge and large assertional parts.The key idea is to 1) use modularizations of the assertional part, 2) use some kind of intermediate structure to find similarities between individual modules, and 3) store information efficiently on external memory. For evaluation purposes, experiments on benchmark and real world ontologies were carried out. We show that our reasoning infrastructure can handle up to 1 billion ABox assertions. To the best of our knowledge this is the first system to provide sound and complete reasoning over SHI ontologies with such a huge number of assertions.".

- 11 abstract "DBpedia is the semantic mirror of Wikipedia. DBpedia extracts information from Wikipedia and stores it in a semantic knowledge base. This semantic feature relies in making complex queries inferring relations among articles which sometimes are missing in Wikipedia. This difference generates an information gap between DBpedia and Wikipedia. Could be improved Wikipedia with DBpedia new information to reduce this gap? How this new information should be added to Wikipedia? In this article, we propose a path indexing algorithm (PIA) who takes a data set of a DBPedia query and returns the best representative path to be applied in the Wikipedia. We evaluate the results of applying PIA to express the relation between people and their birth city.".
