Suggestions

Hi YuYan,
Thank you very much for reading my page and your kind suggestions:

1. In the first paragraph of the introduction section, I tried to elaborate the case where User Adaptive Systems are appreciated as some questions which establish the foundation of this field. As this assignment was about reviewing two papers, I tried to be loyal to the material of the papers and just evaluate them in conclusion sections. I didn't find presenting a separate motivational example, any useful as two concrete and complete cases (experiments) are reviewed.
2. You're right, I just changed its position to be presented before the procedure section.

Thanks again for your valuable suggestions ;)
