  1. Impact of Using Semantic Social Networks On Organizations Zahra Amin Nayeri Ali Fatalian University of Tehran

  2. PresentationOutline • Centeralization or Decentralization ? • SEBSON Framework: a Semantic based Social Network Framework • Implementation and test Issues • Semantic Social Networks VS. Non Semantic Social Networks

  3. Introduction Increasing tendency toward decentralized structure in business world.

  4. Introduction • Chaos and disorder ? • Constituents of a decentralized organization : • Workgroups • Catalysts • Controllers

  5. Introduction Benefits of using semantic social networks : 1- It reduces the risks associated with decentralization. 2-It reacts faster to changes in environment and organization.

  6. Introduction 3- It generates SN’s and social mining resources faster and cheaper. 4- Improves workflow , synergy and cooperation. 5- Enables easier monitoring and management.

  7. Introduction • SEBSON framework. • Objectives : • To prove the superiority of decentralization in certain environments. • To study abilities enabled by using SEBSON. • Two real world test cases .

  8. Centralization or Decentralization ? • Decentralized Organization : • Norms Rather than rules. • Distribution of Power. • Faster decision making and reaction to change • Efficiency and Performance. • Entrepreneurship

  9. Centralization or Decentralization ? • Hybrid Structure • Has pros of both structures: • Bottom up decision making • Adaption to change

  10. Centralization or Decentralization ? Partitions Work groups Cores

  11. Semantic Web Technologies • Resource Description Framework (RDF) • RDF schema (RDFS) • Dublin Core ™ • Friend of a Friend ( FOAF ) • Jena Semantic Web Framework

  12. Semantic Web Technologies • Dublin Core RDF and Ontologies : • used to describe business procedures. • FOAF : • Social Interactions between workgroups and partitions

  13. Semantic Web Technologies • Reasoning & Knowledge management: • Jena Inference Engine • SPARQL language • RDF triplet stores And SDB layer • Agents : • Social Network Inspector • Social Network Analyzer • Project Manager

  14. SEBSON Framework Programmers & Administrators Users Agents

  15. Environment Issues • Not all environments are suitable for decentralization. • Environment requirements : • Change with fast pace. • Shared interests and functionalities. • Need for synergy and cooperation

  16. Simulation Issues • Process : • Finding possible relations using RDF & DC descriptions • Establishing new relations and updating FOAF tags • Results : • Semantic social network. • Information about structure of organization

  17. Semantic Social Networks VS. Non Semantic Social Networks • Non Semantic Social Network Visualization :

  18. Semantic Social Networks VS. Non Semantic Social Networks • Semantic Social Network Visualization :

  19. Semantic Social Networks VS. Non Semantic Social Networks • SSN : • Better Synergy and Cooperation • Better decision making and adaption to change • Reducing dependency • Better distribution of power • Better adaption to change

  20. Bi - components • SSN : • More reliable • More dependable

  21. Number of K-Cores • SSN : • Relations take place upon projects as opposed to hierarchical positions in SN • Better Synergy and Cooperation

  22. AverageAggregateConstraint • SSN : • More Flexibility • More Adaptability to change • Better Entrepreneurship in workgroups

  23. Betweeness • SSN : • Workgroups are actively in flow of information • Faster and Better Decision Making • Independency of workgroups • More efficiency and performance

  24. Conclusions • Semantic web technologies can be used to ease decentralization • Decentralization benefits were proved : • Synergy • Decision making • Flexibility • Reliability • Adaptability to change • Performance • Efficiency

  25. Conclusions • Additional advantages of using Semantic social networks in organizations : • Providing tools for better management and control • Presenting structural information for social network mining • Making partner finding and recruiting easier
