Interactive web video advertising with context analysis and search

Online media services and electronic commerce are booming recently. Previous studies have been devoted to contextual advertising, but few work deals with interactive web advertising. In this paper, we propose to put users in the loop of collecting contextual ad information with an interaction process, establishing semantic ad links across media platforms. Given an ad video, the key frames with explicit product information are located, which allow users to click favorite key frames for searching ads interactively. A three-stage contextual search is applied to find relevant products or services from web pages, i.e., searching visually similar product images on shopping websites, ranking product tags by text aggregation, and re-search textual items consisting of semantic meaningful tags to make a recommendation. In addition, users can choose automatically suggested keywords to reflect their intentions. Subjective evaluation has demonstrated the effectiveness of the proposed approach to interactive video advertising over the Web. ? 2010 IEEE.EI
