introduction & use cases

Hi all
I'm Hui Miao from Digital Media at Samsung. I joined the company last year
and worked on intelligent systems in digital televisions. My background is
data mining and software engineering. Before joining Samsung, I did several
intelligent agents related research projects in Seoul National University.
Currently I'm working in the university collaborating with researchers
there. This is my first time working in W3C. Since I'm a new comer
in standardization and also w3c, there must be lots of things to be learned.
However, I'm very interested in this kind of work and will work harder. : )

About the use case, we are interested in the recommendation systems
currently. 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
