SHER: A Scalable Highly Expressive Reasoner

Achille Fokoue
Software Research Group
IBM Thomas J. Watson Research Center
Hawthorne, New York

An impediment to the realization of the semantic web vision has been the inability of semantic web systems to successfully scale to large and expressive knowledge bases. In this talk, I will present advances in scaling ontology reasoning made over the past three years at IBM Research. I will also discuss three concrete applications of scalable ontology reasoning that illustrate its value and potential to transform how information is integrated, analyzed and exchanged. The first application showcases the use of ontology reasoning to automate common labor intensive and error prone clinical tasks, such as cohort selection of patients for clinical trials, infectious disease monitoring, and clinical decision support. An obstacle to automating these tasks is the need to bridge the semantic gap between raw patient data, such as laboratory tests, and the way clinicians interpret this data. The second demonstrates how ontologies can be effectively used to cleanse the output of text analytics over large text corpora. Finally, the last application shows how SHER technology enables efficient semantic search over biomedical literature.

Achille Fokoue (http://domino.researc...) is a researcher at IBM T.J. Watson Research Center, NY, USA. His research interests include knowledge representation and reasoning, data management, information integration, and concrete applications of semantic technologies in an enterprise context. His current work focuses on developing theories, algorithms and systems for scaling reasoning over large and very expressive description logics knowledge bases. He currently serves as IBM representative at the W3C OWL 2.0 Working Group.

    I think SHER is one of the most important contributions to the use of semantic web technology in real world applications. Without scaling, we can only work on toy problems and is just not getting us anywhere.

    Very clear presentation on a very useful subject.

    Enjoyed it! At least I think of know what I did not quite understand - e.g. - does the model abstraction which allows the weeding out of inconsistencies (e.g. "a singleton course instructor cannot be both man and a woman") , in and of itself yield the performance gains in querying (e.g. in the other example " give me all the people who visited France last year" ), given that the class membership is not present in the abstraction?

    Interesting talk, but the speaker spent way too much time on the model abstraction. Would have been interesting to see some real examples.

    Seemed a bit too advanced for most in the crowd - perhaps in this case the presentation should have been shortened, with the interested participants following up with the presenter afterwards.

    I really enjoyed the talk. It was advanced but had very good information

    Good and advanced session. I wish we had more time to spend on the actual SHER demo. And I also really enjoyed Panos presentation.
