We propose a method for searching coordinate terms using a traditional Web search engine. “Coordinate terms” are terms which have the same hypernym. There are several research methods that acquire coordinate terms, but they need parsed corpora or a lot of computation time. Our system does not need any preprocessing and can rapidly acquire coordinate terms for any query term. It uses a conventional Web search engine to do two searches where queries are generated by connecting the user’s query term with a conjunction “OR”. It also obtains background context shared by the query term and each returned coordinate term.
