ShyWiki for Knowledge Management

  1. 1. A Spatial Hypertext Wiki for Knowledge Management Carlos Solis and Nour Ali [email_address]
  2. 2. Table of Contents <ul><li>Motivation </li></ul><ul><li>The Knowledge Spiral </li></ul><ul><li>Spatial Hypertext Wiki (ShyWiki) </li></ul><ul><li>Knowledge Conversion in ShyWiki </li></ul><ul><li>Conclusions </li></ul>
  3. 3. Motivation <ul><li>Knowledge management activities require to represent different knowledge types. </li></ul><ul><li>Wikis are a popular solution for knowledge management </li></ul><ul><li>Wikis lack of support to represent different types of knowledge, and to perform the knowledge conversions. </li></ul>
  4. 4. Wikis and the Knowledge Spiral Socialization Externalization Internalization Combination Tacit -> Tacit Tacit->Explicit Explicit -> Tacit Explicit -> Explicit
  5. 5. Knowledge Spiral <ul><li>Externalization </li></ul><ul><ul><li>Electronic Brainstorming Tools. </li></ul></ul><ul><ul><li>Wikis have poor support for brainstorming. </li></ul></ul><ul><li>Combination </li></ul><ul><ul><li>Improving and reorganizing the content. </li></ul></ul><ul><ul><li>Concepts, Relations, and Hyperlinks. </li></ul></ul><ul><li>Internalization </li></ul><ul><ul><li>People Learning. </li></ul></ul><ul><ul><li>A wiki is an electronic repository that can be accessed in internet. </li></ul></ul><ul><li>Socialization </li></ul><ul><ul><li>Individual to individual. </li></ul></ul><ul><ul><li>Wikis could provide socialization with agents. </li></ul></ul>
  6. 6. ShyWiki A Wiki of notes A Spatial Hypertext Wiki
  7. 7. Hypertext types Hyperlink Hyperlink Document centred Hypertext Map Based Hypertext Spatial Hypertext
  8. 8. ShyWiki Model
  9. 9. Externalization This is a braistorming
  10. 10. Externalization The result of the prioritization
  11. 11. Combination Implicit Relations A cluster A list A M to N relation Intersection PartOf Connection A 1 To N relation
  12. 12. Combination Typed Hyperlinks
  13. 13. Combination Templates Template name Edited note Note name Associated concept & Cardinality Default content Typed Hyperlink
  14. 14. Combination Templates Relation, Select associated instances, typed link Template Name Attribute
  15. 15. Socialization with agents RDF projection + Web Services
  16. 16. Scenario usage <ul><li>A typical scenario is requirements elicitation </li></ul><ul><li>-Brainstorming </li></ul><ul><li>-Requirements are reorganized spatially (merged, accepted, rejected) </li></ul><ul><li>-Later, they are defined with more detail using a template. </li></ul>
  17. 17. Related work <ul><li>Semantic wikis </li></ul><ul><li>They are oriented to machines and can represent structured knowledge. </li></ul><ul><li>Spatial hypertext systems. </li></ul><ul><li>VKB, Tinderbox, Not for the web neither collaborative. </li></ul>
  18. 18. Conclusions <ul><li>The knowledge spiral involves different knowledge types and knowledge conversions. </li></ul><ul><li>ShyWiki can represent different knowledge types that are needed to give support to the knowledge conversions in the spiral </li></ul><ul><ul><li>Externalization: Brainstorming </li></ul></ul><ul><ul><li>Combination: Implicit visual structures and structured knowledge </li></ul></ul><ul><ul><li>Virtual Socialization: Knowledge published as RDF and web services provided </li></ul></ul>
  19. 19. Future Work <ul><li>Interpretation of the spatial structures using a spatial parser </li></ul><ul><li>Usability evaluation </li></ul>
  20. 20. <ul><li>Thank you </li></ul>
