Goble %K benchmark %K OAEI %K Ontology Alignment %X The Ontology Alignment Evaluation Initiative is a set of benchmarks for evaluating the performance of ontology alignment systems. In this paper we re-examine the Conference track of the OAEI, with a focus on the degree of agreement between the reference alignments within this track and the opinion of experts. We propose a new version of this benchmark that more closely corresponds to expert opinion and confidence on the matches. The performance of top alignment systems is compared on both versions of the benchmark. Additionally, a general method for crowdsourcing the development of more benchmarks of this type using Amazon’s Mechanical Turk is introduced and shown to be scalable, cost-effective and to agree well with expert opinion. %B 13th International Semantic Web Conference (ISWC 2014) %I Lecture Notes in Computer Science, Springer %C Riva del Garda, Italy %V 8797 %P 148-163 %8 10/2014 %G eng %0 Conference Paper %B The Semantic Web - ISWC 2013 - 12th International Semantic Web Conference, Sydney, NSW, Australia, October 21-25, 2013, Proceedings, Part II %D 2013 %T A Linked-Data-Driven and Semantically-Enabled Journal Portal for Scientometrics %A Yingjie Hu %A Krzysztof Janowicz %A Grant McKenzie %A Kunal Sengupta %A Pascal Hitzler %E Harith Alani %E Lalana Kagal %E Achille Fokoue %E Paul T.

Noy %E Eva Blomqvist %X We present a new approach to adding closed world reasoning to the Web Ontology Language OWL. It transcends previous work on circumscriptive description logics which had the drawback of yielding an undecidable logic unless severe restrictions were imposed. In particular, it was not possible, in general, to apply local closure to roles. In this paper, we provide a new approach, called grounded circumscription, which is applicable to SROIQ and other description logics around OWL without these restrictions. We show that the resulting language is decidable, and we derive an upper complexity bound. We also provide a decision procedure in the form of a tableaux algorithm. %B The Semantic Web - ISWC 2011 - 10th International Semantic Web Conference, Bonn, Germany, October 23-27, 2011, Proceedings, Part I %I Springer %V 7031 %P 617-632 %8 10/2011 %G eng %R 10.1007/978-3-642-25073-6_39
