an "interactive search workflow" application that allows users to refine their search queries by providing alternative or additional search parameters on-the-fly (e.g. tags, translations & other sources), while showing live search results from various data sources such as yahoo, flickr & youtube.
the application generates a hierarchical tree visualization. the blue nodes represent the type of source where the related words come from. the white nodes can be added to the Query List.
