Social-sensed multimedia search. Personalized
search has been studied for many years in
the text domain. The main target has been to
construct accurate and complete user profiles
for re-ranking the search results by measuring
the distance between the search results and user
profiles. More specifically, the user profiles
were represented by an ontology22 and topics,
which are mined from the metadata, search
logs, and social media. Recently, some of these
techniques have been transferred into a personalized
image or video search, especially for
image searches in Flickr.
