Frist meet and talk with prof. Vilas. – It was quite good, at least the topic has been scoped down. From 'Personalization services for e-learning in a Peer-to-Peer Semantic Web environment' to 'Personailzation services for e-learning' 
Sound better as he said Peer-to-Peer is on of the concept in Sematic Web, but it is low layer. Now we should focus on the upper layer and let's assume that we have a huge database for an e-learning application so that we can access and provide some services to. – It is good then.
He also said he would emprasize for 'special study' on finding other related works and defined how our works would be better – also we needed to find the way for evaluation. – That's the concept for working – needed to do some progress and presentation on the coming Friday.
