Advice needed on Semantic web conference, Journal

Hi,

I have developed  a semantic web based content based video/image search
engine, as part of my master's thesis. I hope it would provide a new way for
searching for multimedia content, also making semantic web more known to
people. Could you suggest some semantic web conferences/ Journals which
would be good for me to publish my work this year. I am located in USA.

Thanks & Regards
Sancho
