  • Design & Development of a Knowledge Community System Le Phan Huu Bang Project Number: H022560 Advisor: Assoc Prof Poo Chiang Choon, Danny
  • Agenda Introduction   System Components  Implementation  Conclusion  Demonstration  Q&A
  • Introduction – Why K-Comm? Knowledge sharing is important  ◦ Vital for company to survive ◦ Many questions are repetitive ◦ Knowledge can only grow by sharing Difficult to encourage sharing  knowledge ◦ People are reluctant to share ◦ Knowledge = Power ◦ People do not trust each other
  • System at a Glance
  • K-Comm – The Features K-Comm is a knowledge-focused social  network  Social Network Environment: blogs, forums, friends, groups, file sharing, etc.  Knowledge-based Features: ◦ Questions & answers: seek and contribute knowledge ◦ Get linked to people who might have the answers ◦ Share knowledge ◦ Collaborate with like-minded people
  • Similar Systems
  • K-Comm – The Selling Points Combination of various features   Intuitive UI  Not another Yahoo! Or Google Answers  Not another social network  Not another blog  Not another forum
  • K-Comm Comparison Yahoo! & Social Blogs & Features Goggle KMS K-Comm Networks Forums Answers Blogs Forums Friendship Groups Q&A Quality control Enhanced Domain General Personal Specific Specific General
  • System Components Core Library Q&A Display User Profiling Widgets Questions & Answers Rating K-Comm System Social Networking Point System User Interface Skill Level System
  • User Profiling Package
  • Social Networking
  • Questions & Answers Package Ask and answer questions   Search for questions and answers  Evaluate questions and answers  Organize questions and answers
  • Ask and Answer Questions Users can ask and answer questions   System will evaluate the users, the questions and answers according to the activities and ratings  Questions are categorized into different categories and by using tags  List of categories can be updated
  • Ask and Answer Questions
  • Search and Organize Q&As Using the Search box   Using the Latest and Interesting tab  Using the widgets
  • Evaluation Evaluate the questions and answers  System will analyze and evaluate the questioners  and answers
  • User Interface Simple, intuitive and user friendly   Look cool: Ajax, drag & drop  I can find what I want to find  Flexible, easy to use and learn
  • Implementation Elgg framework as a foundamental  platform for the system  Elgg K-Comm ◦ Social networking ◦ Plug-in  Q&As, customized look and feels ◦ Elgg Data Model  more Object-oriented approach ◦ Metadata and annotations  users’ contributions and knowledge value estimation ◦ Widget  tools to manage and organize Q&As
  • Elgg Data Model
  • Core Library Question   Answer  Category  Skillrecord
  • Core Library
  • Widgets Each widget has a view and edit  interface  Register the widget with Elgg through the start.php in the Q&A plug-in
  • Widgets
  • User Interface Implemented as a plug-in  extensible and  reusable  Provide the layout for Q&A component  Make use of jQuery plug in for effects
  • Skill Level System Ratings of answers and questions can  be a good basis to evaluate the level of knowledge that the poster possesses  Help the users identify the potential of knowledge sharer  Something missing from other similar systems
  • Skill Level System – An example John Mary 25 25 20 20 15 15 Best Answers Best Answers Answer Count Answer Count Question Count Question Count Answer Rating 10 Answer Rating 10 Question Rating Question Rating 5 5 0 0 Car Computer Travel Car Computer Travel
  • Skill Level System – An Example Skill Level for John and Mary John Car Computer Travel Mary 0 1 2 3 4 5 6 7 8 9
  • Skill Level System Requirements In scale of 10   Calculated based on ◦ Ratings of questions and answers ◦ Total number of questions and answers ◦ Best answers Not decrease due to inactivity 
  • Skill Level System - Formula
  • Conclusion Specifications of the system  ◦ Definition ◦ Features ◦ Characteristics Implementation approach   Implement fundamental core features and components  Maintain flexibility, extensibility an reusability
  • Future Features Presentation  ◦ Concept-map, mind map ◦ Tree view Analysis of Q&As  ◦ Concept extraction  Automated Q&As ◦ Information retrieval: e.g. searching based on profile or relevant hits Tag relationship 
