7th AIS SigPrag International Conference on Pragmatic Web (ICPW 2012)

  1. 1. The Pragmatic Web (and its many relations) Adrian Paschke Hans WeigandCorporate Semantic Web Faculty of Economics Freie Universität Berlin Tilburg University Co-Chairs Pragmatic Web www.pragmaticweb.info7th AIS SIGPRAG International Conference Session on Pragmatic Web at 6th International Symposium on Rules RuleML 2012 Montpellier, France, August 2012
  2. 2. The Semantic Web• "The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation." – Tim Berners-Lee, James Hendler, Ora Lassila, The Semantic Web 2007 W3C Semantic Web Stack• „Make the Web understandable for machines“ 2
  3. 3. Core Semantic Technologies1. Rules – Describe conclusions and reactions from given information (inference) – Declarative knowledge representation: “express what is valid, the responsibility to interpret this and to decide on how to do it is delegated to an interpreter / reasoner”2. Ontologies – Ontologies described the common knowledge of a domain (semantics): • “An ontology is an explicit specification of a conceptualization “ T. Gruber  Semantics interoperability between (connected) vocabularies 3
  4. 4. Corporate Semantic WebCorporate Semantic Web (CSW) isused to describe the application ofSemantic Web technologies andKnowledge Managementmethodologies in corporateenvironments. 4
  5. 5. Corporate Semantic Web 1. Application of Semantic Web technologies in enterprise information systems (Semantic Enterprise) • Collaborative workflows and (business) process management (e.g. Internet of Services, e-Science workflows, Semantic Business Process Management) • Knowledge Management (e.g. Semantic Knowledge Management, Semantic Corporate Memory, Semantic Ad-hoc BI and Semantic CEP) 2. Corporate = Business Context • Application of Semantic Web technologies under economical considerations and business conditions (e.g. cost models, return on investment) 5
  6. 6. Corporate vs. Public Semantic Web• Closed information systems / Intranet solutions with known interfaces between systems, services and domains• Known user groups within enterprise network(s)• Usage of the existing enterprise IT infrastructure, information, and knowledge is constrained by the existing business rules, policies and workflows/processes• Data view: closed, often (semi-)structured data with known data models (e.g., relational, object-oriented, XML, …)• Logic view: partial closed world assumption, partial unique name assumption, constructive views 6
  7. 7. Social Semantic WebThe concept of the Social SemanticWeb subsumes developments inwhich social interactions on the Weblead to the creation of explicit andsemantically rich knowledgerepresentations. (Wikipedia) 7
  8. 8. Social Semantic Web vs.Public/Corporate/Pragmatic Semantic Web• Social Semantic Web = Web of collective knowledge systems• Focus: Tools in which the central social interactions on the Web plays a role. These tools lead to the development of explicit semantic representations• Combines technologies, strategies and methods of the Semantic Web, Social Software and Web 2.0• Finds applications in Corporate Semantic Web as well as Public Semantic Web and in particular Pragmatic Web 8
  9. 9. Pragmatic Web• The Pragmatic Web consists of the tools, practices and theories describing why and how people use information. In contrast to the Syntactic Web and Semantic Web the Pragmatic Web is not only about form or meaning of information, but about interaction which brings about e.g. understanding or commitments. (www.pragmaticweb.info) 9
  10. 10. Language Action Perspective• The Language Action Perspective (LAP) argues that language is not only used for exchanging information, (as in reports or statements etc.) but also to perform actions (as in promises, orders, requests, and declarations etc) (Schoop 2001; Weigand 2003). 10
  11. 11. The Pragmatic Web - Internet as a platform of communication and coordination• Distinguishing the physical event as such (happening in time/space) from – the value it has for humans / agents in terms of commitments – leading e.g. economic value  The value aspect highlights the “why” of the coordination. 11
  12. 12. Organisational Semiotics• Organisational semiotics examines the nature, characteristics and features of information, and studies how information can be best used in the context of organised activities and business domains. (Kecheng Liu et al. 2002) 12
  13. 13. Pragmatic Agent Web The Pragmatic Agent Web utilize theSemantic Web with multiple interactingintelligent agents which collaborate onthe Web and put independent meta data,ontologies and local data into a pragmaticcontext such as communicativesituations, organizational norms, purposesor individual goals and values. (Paschke2007) 13
  14. 14. Pragmatic Agent Web• Utilize the heterogenous Semantic Web resources, meta data and meaning representations with intelligent agents and web-based services with the ability to understand the others intended meaning (pragmatic competence) – Formal Logic Representation vs. (Controlled) Natural Language Representation• Collaborate in a communicative conversation-based process where content and context is interchanged in terms of messages (relation of signs) between senders and receivers (interpreters/users). – Loosley-coupled vs. de-coupled interactions – Fixed negotiation and coordination protocols vs. free conversations• Pragmatic layer/wrapper around semantic/content e.g. by KQML / ACL like speech-act primitives (e.g. assert(content), retract(content), query(kb)) – Model, negotiate and control shared and invividual meanings  requires learning and knowledge adaption / updates 15
  15. 15. Conclusion: Challenges for the Pragmatic WebConnectedness Intelligence / Wisdom understanding Pragmatics principles Knowledge Understanding Sematics patterns Information / Content Understanding relations SyntaxData Ontologies Rules ??? Understanding (Logic) (Logic) (Human Logic + Machine Logic) 16
