This collection of papers stems from the Seventh Workshop on the Representation and Processing of Sign Languages, held in May 2016 as a satellite to the Language Resources and Evaluation Conference in Portorož. While there has been occasional attention for sign languages at the main LREC conference, the main focus there is on spoken languages in their written and spoken forms. This series of workshops, however, offers a forum for researchers focussing on sign languages. For the fifth time, the workshop had sign language corpora as its main topic, however not surprisingly, since during the past years, sign language corpora became a major trend in sign language research. This time, the focus was on corpus mining. Once again, the papers at this workshop clearly identify the potentials of even closer cooperation between sign linguists and sign language engineers, and we think it is events like this that contribute a lot to a better understanding between researchers with completely different backgrounds.
