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 |

Hi in my opinion what you are actually thinking on it's a machine-learning system, so ontologies here are not needed and could be somewhat countert intuitive to use. For example stereomood: http://www.stereomood.com/ uses an approache based on machine learning, if i'm not wrong. The task it's interesting and there are many research on that since some years, the basic approach could be:
Starting from here there are a lot of options to be considered to the actual implementation: i think you basically need a machine learning engine (suche as weka, for example), in order to collect emerging evidence from the data and the metadata, that you could use in some kind of cluster drive approach (with information retrieval) or to map them into a commonsense ontology (which i think it's really hard to construct on topic so fuzzy and personal by means of definition) I hope this help |
