TheSemanticWebisamajorendeavoraimingatenrichingtheexistingWeb withmeta-dataandprocessingmethodssoastoprovideweb-basedsystemswith advanced,so-called“intelligent”,capabilities.Theseadvancedcapabilities,striven forinmostSemanticWebapplicationscenarios,primarilycallforreasoning. Specialized reasoning capabilities are already offered by Semantic Web lan- guagescurrently being developed suchas the OWL family together with Triple, SPARQL,orontology-basedapplication-specificlanguagesandtoolslikeBPEL. Theselanguages,however,aredevelopedmostlyfromfunctionality-centered(e.g. ontologyreasoningoraccessvalidation)orapplication-centered(e.g.Webservice retrievalandcomposition)perspectives.Aperspectivecenteredonthereasoning techniques complementing the above-mentioned activities appears desirable for SemanticWebsystemsandapplications.Moreover,thereisthegeneralreasoning underlying the Semantic Web technologies, such as Description Logics, Hybrid Logics, and others like F-Logic and Logic Programming semantics. Theworkshopserieson“Principles andPracticeofSemanticWebReasoning – PPSWR” beganin 2003(cf. Springer LNCS 3208)in response to the need for a forum for the discussion of emerging work on various forms of reasoning that areorcanbeusedontheSemanticWeb,withastronginterestinrule-basedlan- guagesandmethods.TheworkshopaddressesbothreasoningmethodsfortheSe- manticWeb,andSemanticWebapplicationsrelyinguponvariousformsofreason- ing.Since2003,whentheconferencewasheldinMumbai,India,co-locatedwith ICLP,ASIAN,andFSTTCS,theworkshophasbeenorganizedyearly:thesecond workshop(LNCS3208)tookplacein2004inSt.Malo,France,inconjunctionwith ICLP2004;the thirdworkshoptookplaceintheDagstuhlConferenceCenterin Germany,withinaoneweekDagstuhlSeminar(LNCS3703). The technicalprogramofPPSWR2006comprisedaninvited talk by Harold Boleyon“The RuleMLFamily of WebRuleLanguages”,andthepresentationof 14 refereed technical articles selected by the ProgramCommittee among the 25 submitted.These14articlesdiscussvariousaspectsofreasoningontheSemantic Web ranging from more theoretical work on reasoning methods that can be applied to the Semantic Web, concrete reasoning methods and query languages for the Semantic Web, to practical applications. Besides the presentationof the technical articles, one sessionwas devoted to thepresentationanddemonstrationof6systems,allofthemrelatedtoreasoning IV Preface on the Semantic Web. A description of eachof these systems is also part of this volume. Duringthe workshop,informalon-siteproceedingsweredistributed.Thepa- pers in this volume have been revised by the authors based on the comments fromthe refereeingstageandensuingdiscussionsduringthe workshopandhave been subject to a final acceptance by the ProgramCommittee.

The RuleML family of Web rule languages contains deriva- tion (deduction)rulelanguages, whichthemselveshaveawebized Data- log language astheirinnercore. DatalogRuleML’s atomicformulas can be(un)keyedand (un)ordered.InheritingtheDatalog features, Hornlog RuleMLaddsfunctional expressions as terms. In Hornlogwith equality, suchuninterpreted(constructor-like)functionsarecomplementedbyin- terpreted(equation-defined)functions.Thesearedescribedbyfurtheror- thogonaldimensions“single-vs.set-valued”and“first-vs.higher-order”. Combinedmodallogicsapplyspecialrelationsasoperatorstoatomswith an uninterpretedrelation, complementing the usual interpreted ones. 1 Introduction Efforts in Web rules have steadily increased since they were brought into focus by the RuleML Initiative [http://ruleml.org] in 2000, includ- ing DARPA’s DAML Rules [http://www.daml.org/rules], IST’s REWERSE [http://rewerse.net], ISO’s Common Logic [http://cl.tamu.edu], OMG’s Produc- tion Rule Representation (PRR) [http://www.omg.org/docs/bmi/06-02-08.pdf] as well as Semantics of Business Vocabulary and Business Rules (SBVR) [http://www.businessrulesgroup.org/sbvr.shtml], and W3C’s Rule Interchange For- mat (RIF) [http://www.w3.org/2005/rules]. RuleML has co-evolved with some of these other efforts as well as with the Semantic Web Rule Language (SWRL) [http://www.w3.org/Submission/SWRL], the Semantic Web Services Language (SWSL) [http://www.w3.org/Submission/SWSF-SWSL], and the Web Rule Lan- guage (WRL) [http://www.w3.org/Submission/WRL]. This has been supported by, and influenced, RuleML’s modular design. The specification of RuleML constitutes a modular family of Web sublan- guages,whoserootaccessesthelanguageasawholeandwhosemembersidentify customized,combinablesubsetsofthelanguage.Eachofthefamily’ssublanguages has anXML Schema definition,Web-addressedby a URI, whichpermits inheri- tancebetweensublanguageschemasandprecisereferencetotherequiredexpres- siveness.The family structure providesan expressiveinclusionhierarchyfor the (cid:2) Thanks to David Hirtle for creating the family’s XML Schemas, and the RuleML SteeringCommitteeforguidance.ThisresearchwaspartiallysupportedbyNSERC.
