 * Topic: "OWL 2: Tools & Applications"


 * Abstract: This is the second of our two back-to-back sessions devoted to OWL 2. Our session chiar, Professor IanHorrocks (co-chair of the W3C OWL 2 Working Group) has brought together an expert panel of OWL 2 researchers and developers to show us some of the state-of-the-art in OWL 2 tools and applications. Again, we will have about 30 minutes for open discussion after all the panel briefings. The panelists and their presentations will include:


 * Please refer also Professor IanHorrocks' two preceding session in the series:
 * * "Scalable Ontology-Based Information Systems" - ConferenceCall_2010_07_22
 * * "OWL 2: The Next Generation" - ConferenceCall_2010_07_29

The OWL API is widely used in various prominent software projects. For example, it underpins various OWL editors and browsers such as Protege 4, The [[NeOn] Toolkit], Swoop and OWL Sight. Moreover, many OWL 2 reasoners, such as [[FaCT]++], HermiT, JCel, Pellet and Racer provide implementations of the OWL API reasoner interface. This talk will cover the main features and design philosophy behind the API, and will give some idea of how the API is used in applications.
 * The OWL API: a Java API for working with OWL 2 ontologies - [ slides ]
 * By: MatthewHorridge (University of Manchester)
 * Abstract: This talk will present the OWL API, which is a high level Application Programming Interface (API) for working with OWL 2 ontologies.
 * Resources:
 * The "OWL API" open source project site - http://owlapi.sourceforge.net


 * The Protégé Tool Suite for Editing OWL Ontologies - [ slides ]
 * By: TimothyRedmond and TaniaTudorache (Stanford-BMIR)
 * Abstract: The Protégé group has developed a suite of tools for editing OWL 2 ontologies. Protégé 4 is the tool of choice for editors who want full OWL 2 support.  Recent developments in Protégé 4 include client-server support  allowing multiple users to access and edit an ontology simultaneously.  Clients can choose to either access the ontology in an offline (svn/cvs) mode or in a live online mode where changes are seen as they occur.  We will talk about the Protégé 4 database backend that allows the storage and fast querying of large ontologies.  In addition we will present WebProtege, which is a powerful collaborative ontology editor that users  access through their web browser.  This version of WebProtégé provides support for collaborative discussion threads and includes full OWL 2 support.

 * The NeOn Toolkit - [ slides ]
 * By: AndreasHarth (The NeOn Project; Institute AIFB; Karsruhe Institute of Technology)
 * Abstract: The NeOn Toolkit is a state-of-the-art, open source multi-platform ontology engineering environment, which provides comprehensive support for the ontology engineering life-cycle. The toolkit is based on the Eclipse platform, a leading development environment, and provides an extensive set of plug-ins (currently over 30 plug-ins are available) covering a variety of ontology engineering activities. Starting with version 2.3 the NeOn Toolkit is based on the OWL API and supports OWL2 features.  The talk will cover basic NTK functionality and the set of OWL2 features that NTK supports.

 * The NeOn Toolkit wiki - http://neon-toolkit.org/wiki/Main_Page


 * Pellet: OWL 2 Reasoner - [ slides ]
 * By: EvrenSirin (Clark & Parsia)
 * Abstract: This talk will introduce OWL 2 reasoner Pellet. Pellet is a sound and complete reasoner that supports all the features in OWL 2. In addition to the core reasoning services consistency checking, classification, and realization; it provides services for SPARQL query answering, explanation of entailments, and module extraction. This talk will briefly describe these features as well as the reasoning extensions to Pellet for closed-world data validation, qualitative spatial reasoning and probabilistic reasoning. Some examples of real-world applications using Pellet will also be described.

 * Application of OASIS Integrated Collaboration Object Model (ICOM) with Oracle Database 11g Semantic Technologies - [ slides ]
 * By: EricChan, RameshVasudevan & AlanWu (ICOM; Oracle); DeirdreLee & LauraDragan (ICOM; DERI)
 * Abstract: OASIS Integrated Collaboration Object Model (ICOM), a proposed standard for integrated and interoperable enterprise collaboration, is an interesting application area for semantic database management tools in Oracle Database 11g Release 2. ICOM is a proposed standard ontology to integrate a complete range of collaboration activities for interoperable collaboration environments. It promotes seamless transitions among the collaboration activities to eliminate the fragmentation of collaboration tools. ICOM is defined from the outset for concomitant representations in Resource Description Framework (RDF) and Unified Modeling Language (UML), as well as in relational tables by some customized Object-Relational Mapping (ORM) schemes. Oracle Beehive collaboration service, which is a provider of ICOM, manages the ICOM-compatible data in Oracle Database to achieve high availability and scalability. By generating the ICOM RDF triples from the relational schema, Oracle database semantic technologies complement the ORM solutions to provide access to RDF/OWL and OO representations of the same dataset in RDBMS. Members of ICOM TC, Oracle Beehive Collaboration Technologies, and Oracle Database Semantic Technologies will jointly present the ICOM RDF modeling of the Ontolog forum data, including member profiles, discussion messages, wiki pages, conferences, etc., and demonstrate the Oracle Database support of OWL 2 RL, SPARQL, and SQL query interfaces for faceted search applications of ICOM RDF representations.

PeterYim: now speaking - Mr. MatthewHorridge (U of Manchester) - "The OWL API: a Java API for working with OWL 2 ontologies"

FrankChum: Are the versions backward compatible?

Axel Polleres: What's the relation OWLAPI vs dig regarding the reasoning interface?

PeterYim: (just for those who are unfamiliar with the process) we will hold Q&A until after all the presentations are done. We should have time for discussion then, hopefully. Feel free to capture your questions or remarks here, partly using this as a placeholder, and partly to document that for the records

PeterYim: now speaking - Dr. TimRedmond & Dr. TaniaTudorache (Stanford-BMIR) - "The Protege Tool Suite for Editing OWL Ontologies"

NicolasRouquette: It is often difficult to tell which ontology asserted a particular axiom and which axioms a particular ontology asserts.

NicolasRouquette: The class browser view in particular shows all classes across all loaded ontologies -- although we can show the ontology-specific prefix to tell which ontology declares a particular class, it is sometimes difficult to get a sense of all the classes declared in a particular ontology.

PeterYim: now speaking - Dr. AndreasHarth (The NeOn Project; Institute AIFB, Karlsruhe Institute of Technology) - "The NeOn Toolkit"

PeterYim: now speaking - Dr. EvrenSirin (Clark & Parsia) - "Pellet: OWL 2 Reasoner"

Axel Polleres: afraid I need to run, thanks for the interesting talks!

PeterYim: thank you for your participation - the entire proceedings will be available on our archives - slides, audio recording, chat transcript, and all (just come back to the session page in a day or two)

RaviSharma: @Evren - Pronto, does it break the distribution into histograms and for each histogram you get the same reasoned answer i.e. is it equivalent to making it deterministic within the histogram for a given axiom (or / Assertion)?

RaviSharma: @Evren - how does Pronto discover inferences that are probabilistic does it apply the above process in previous question in reverse to fill a particular histogram with population / samples?

EvrenSirin: Pronto uses lexicographic entailment algorithms to perform default probabilistic reasoning

EvrenSirin: The semantics is based on first order probabilistic logic

EvrenSirin: The computation of probabilistic inferences has several steps and involves solving linear equations among others

Enrico Franconi: @Evren, which is the reference for the integrity constraint validator? Is it just what we can find on the web page?

EvrenSirin: @Enrico, longer technical report has several corrections: http://www.cs.rpi.edu/%7Etaoj2/publications/ic-tr-2010-0607.pdf

NicolasRouquette: Thanks Evren!

EvrenSirin: There is: Jiao Tao, EvrenSirin, Jie Bao, Deborah L. McGuinness, Integrity Constraints in OWL, AAAI2010

EvrenSirin: http://www.aaai.org/ocs/index.php/AAAI/AAAI10/paper/download/1931/2229
