Tropes Zoom was a desktop search engine and semantic analysis software from Acetic/Semantic-Knowledge. Originally written by Pierre Molette in 1994 in partnership with University Paris 8, it was the first search engine based on semantic networks to be widely known.Unlike other search engines, Tropes Zoom suggested that the user replace each identified word with a hypernym. Thus, the search is not carried out directly on the words chosen, but on the totality of their semantic equivalents.
