To write in a foreign language is a difficult task, even for an experienced author. Problems include choosing the right word or preposition in a given context, finding a wording which is commonly used, and avoiding the use of grammatical forms which reflect the author's native language. The Netspeak Web service assists authors to overcome these issues by using the World Wide Web as a source of common language. The service can be queried with short text phrases to determine their customariness on the Web. Wildcard characters can be added to the query to search for variations and synonyms of the query phrase, which will be returned as ranked list with respect to their occurence frequency on the Web.
