The document discusses options for building next-generation knowledge building environments. It compares the advantages and disadvantages of different architectural approaches including Knowledge Forum Lite, Advanced, Basic; Google Web Toolkit; PHP+MySQL. It also lists recent and current related projects and possibilities for visualization and semantic analysis tools to integrate. The document aims to determine the best architecture to keep the environment open, scalable, and coordinate different efforts into a coherent framework.

1. Building Next-Generation Knowledge Building Environments Guangzhou, July 12

2. Knowledge Forum Lite Advanced Basic Analytic Tools e.g.: Contribution, SocialNetwork, VocabularyGrowth, Writing, SemanticOverlap, KSV, KBDeX, Lexical Analytic Tools… Java (client) Perl (browser) Tuplestore

3. Knowledge Forum Lite Advanced Basic OLI-KF ? Analytic Tools Java Perl Google Web Toolkit (GWT) … PHP Tuplestore MySQL

4. Google Web Toolkit We write code in Java Google translates it into JavaScript Works with modern browsers Applied in Google Wave, Google Ads, etc Open source Scalable, flexible easy to switch from TupleBase to MySQL Possible to integrate with JavaScript-based visualization techniques, e.g. Protovis

5. PHP+MySQL Motivations SmartBoard/Interactive White Board Mobile devices Widely-used Open source

6. Questions Which architecture? How to keep it open and scalable? How to coordinate all efforts to a coherent framework?

7. Recent and current projects OLI-KF (Carnegie-Mellon) Knowledge Space Visualizer (Toronto) KBDeX (Shizuoka, Japan) Lexical analytic tools (Quebec) Knowledge Connections Analyzer (H.K.) …
