The service provider will do collaborative filtering based on metadata in various kinds of videos from different content providers, like epg in tv programs, mpeg-7, and etc. Some video on the web does not have explicit metadata and html extraction is required to including such resource in the recommendation. The use scenarios would be like the following: content creator can create, update, delete, query the metadata easily and add access rights to it content provider organize the metadata and video from content creator. the metadata would be in the video file or store metadata and video separately recommendation service provider query the metadata from the content provider and do related tasks end user can get the metadata also The standardized metadata makes related data mining, recommendation easier. In mepg-7, there're related parts, however, it merely appears in other standards. Youtube like video would be one of the contents, however, various content providers in this category usually have different medata and some of them do not provide explicit api. I'm looking forwards to work in the group with all of you. Have a good day. Hui
