User generated content, e.g. available through social networking sites on the Web, offers a wealth of information. The aim of PARIS is to study adequate natural language, image and video understanding techniques to make use of this information. This is challenging as user generated content is often present in language that is not well-formed or in visual material that is not professionally captured. An important application of PARIS to evaluate the natural language, image and video understanding techniques is personalised advertising, where advertisements are searched and generated that fit the world of living of users. This personalisation should remain in line with legal requirements concerning personal data protection and intellectual property rights.
