- 2. 2 Agenda • About Corporate Semantic Web • Corporate Semantic Engineer • Corporate Semantic Search • Corporate Semantic Collaboration • Summary and Future
- 3. 3 Semantic Web – An Introduction • "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 • „Make the Web understandable for machines“
- 4. 4 Semantic Technologies 1. 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
- 5. 5 About Corporate Semantic Web 1. Application of Semantic Web technologies in enterprise information systems (Semantic Enterprise) • Collaborative workflows and (business) process management (e.g. e-Science workflows, Semantic Business Process Management) • Knowledge Management (e.g. Semantic Knowledge Management, Semantic Corporate Memory) 2. Corporate = Business Context • Application of Semantic Web technologies under economical considerations and business conditions (e.g. cost models, return on investment)

- 8. 8 Semantic Content (Semantic Data) 1. Automatic extraction of semantic from non-semantic data • Linked Data Extraction • Ontology Learning 2. (New) Semantic Data and Knowledge Engineering and Development • Manual (e.g. semantic text editor, semantic Wiki, semantic CMS, ontology-/rule-engineering) • Automated (e.g., user activity mining, text analysis)
- 9. 9 Semantic Knowledge Semantic Knowledge Management and “Semantic Organizational Memory" • Relevant knowledge • e.g. reuse of knowledge, faster search, faster knowledge transfer, efficient processes, etc. • Semantic archives and knowledge repositories • e.g. Linked Data, knowledge clouds, semantic Wikis, semantic knowledge bases such as triplestores, semantic personal CMS, etc. • Semantic integration of data from different heterogeneous sources of corporate knowledge • Analysis of the semantic data, in order to detect implicit knowledge and semantically represent it
- 10. 10 Semantic Applications (Semantic Intelligence) Semantic applications for • Corporate Semantic Engineering • Methods and tools for the management of corporate information and processes • Support for the development of semantic enterprise solutions and products/services • Semantic Corporate Search • Solutions for semantic search in information repositories • Semantic Corporate Collaboration • New semantic collaboration platforms with which information, processes and knowledge can be collaboratively share, used and managed
- 11. 11 • Learning and Training • Decision makers and employees • Economic considerations, • i.e. business context • Estimation of costs and benefits • Development and usage of new Corporate Semantic Web technologies • Incentives for adoption and use of semantic technologies Pragmatics

- 13. 13 Domains of the Corporate Semantic Web • Corporate Semantic Engineering • Methods and tools for the precise, high-quality and economical development and management of ontologies and rule bases for business information and processes • Semantic support for the software and process engineering • Semantic Corporate Search • Solutions for the semantic search in controlled information resources with defined quality of service improvements • Semantic Corporate Collaboration • New semantic collaboration and support platforms with which different enterprise domains or parts of virtual organizations can collaboratively collect, use and manage information, processes / services and knowledge
- 14. 14 • Ontology modularization and integration • Ontology versioning • Ontology cost estimation models for corporation • Ontology evaluation Corporate Semantic Engineering Corporate Semantic Engineering
- 15. 15 Example: Corporate Ontologies • Ontology supported Semantic Knowledge • Semantic Bridges between Heterogeneous Information Systems • Asynchronous evolution of the stand-alone systems and underlying corporate (background) knowledge Corporate Wikis Corporate Blogs Corporate Websites Corporate Ontologies CRM Corporate Structure
- 16. 16 Selection/Integration/Development EvaluationValidation Feedback Tracking Population Deployme nt Reporting ENGINEERING USAGE Corporate Ontology Lifecycle Model (COLM) Example: Ontology Engineering and Life Cycle
- 17. 17 Example: Modularization and Integration Integrated View Modul 1 … … Modul n Modul 2 Modul n-1 Core Ontology Domain Ontology Application Ontology Domain 1 Domain 2
- 18. 18 Semantic Corporate Search • Search in non-semantic data • Search personalization • Multimedia search • Search contextualization Corporate Semantic Search
- 19. 19 Example Personalized Search Skill Ontology Example: Query „Java“ (+ Personal Skill Profile (Java + C++ Knowledge) ) d (Java, C++) = d (Java, Object Oriented) + d (C++, Object Oriented) = (0.25-0.0.0625) + (0.25-0.0625) = 0.375 sim(Java, C++) = 1 – 0.375 = 0.625 (Semantic Similarity) => also propose job offers for C++ programmer
- 20. 20 Semantic Search Iterative search by the user. Advantage: low entry costs Challenege: query strategy Text corpus is fact base. Advantage: unstructured content accessible Challenge: ask a valid question Background-knowledge used during search. Advantage: captures all latent answers Challenge: Ontology design
- 21. 21 Semantic Corporate Collaboration • Knowledge extraction by mining user activities • Collaborative tools for modeling ontologies and knowledge • Dynamic access to distributed knowledge • Evolution of ontologies and knowledge by collaborative work Corporate Semantic Collaboration
- 22. 22 Information Sources: Knowledge Management: Workflows Knowledge Semantik Information Events & Process Context Relations & Interpretation Content BPM BPMBPM BPM Work flow Workflow Literature Colleagues Databases Experts Product Contents Example: Semantic Collaboration Workflows and BPM Business Processes
- 23. 23 Example: Mediated Semantic Business Process Modeling Heterogeneous Corporate/Domain Ontologies
- 24. 24 Example: Semantic Business Process Management % receive query and delegate it to another party rcvMsg(CID,esb, Requester, acl_query-ref, Query) :- responsibleRole(Agent, Query), sendMsg(Sub-CID,esb,Agent,acl_query-ref, Query), rcvMsg(Sub-CID,esb,Agent,acl_inform-ref, Answer), ... (other goals)... sendMsg(CID,esb,Requester,acl_inform-ref,Answer). •Paschke, Rule Responder BPM / ITSM Project •Barnickel, Böttcher, Paschke, Semantic Mediation of Information Flow in Cross-Organizational Business Process Modeling, 5th Int.

- 25. 25 Corporate Semantic Web What comes next?
- 26. 26 Corporate Semantic Web Corporate Semantic Web (CSW) focuses on the application of Semantic Web technologies and semantic Knowledge Management methodologies in corporate environments.
- 27. 27 Corporate vs. Public Semantic Web • Closed information systems / Intranet solutions with often 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 structured data with known data models (e.g., relational, object-oriented, XML, …) • Logic view: partial closed world assumption, partial unique name assumption, scoped constructive views
- 28. 28 Social Semantic Web vs. Corporate 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
- 29. 29 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
