Hi, I am quite new at the field of semantic web and i need some
help in order to conduct my research. I came up with the idea of
a tangible interface which would take as an input the
physiological sense of the user and recognize the emotion of it
and the system can recommended simultaneously a playlist of
songs and a collection of pictures. My basic idea is when for
example a user is sad, the system can recommended a playlist of
happy songs and a collection of pictures that provides positive
feelings to the user. As for the methodology of the system, I
thought about align 3 ontologies together (emotion, music,
pictures). Is it right the way that I am thinking or there is
another way like tag acquisition? If it is possible, what
sources shall i look into? And about the recommendation method,
should i look for the semantic-based recommendation?  Also, in
the recommendation machines why knowledge base(construction of
ontologies) is an important component?  Thank a lot for your
valuable help, Debbie  asked 19 Dec
