Communicating KnowledgeCommunicating KnowledgeLesson to Learn and Conclusion

• Commercializing semantic technology has already been come true in Asia.

• Scalability : 1B is not enough. We need 10B~100B!!! We have to consider distributed architecture!

• Data interoperability is the KEY for NG Mobile, Ubiquitous Computing and also the Web.

• Valuable Applications : Semantic Search, Personalization and Recommendation.

• We are going to real service business based on semantic web.
