Information and Communication Technologies have radically changed the way in which we access and share information. However, accessibility for all is still far from being a reality. People with Intellectual or Developmental Disabilities (IDD) currently have very limited access to the information society and, in particular, to social media websites. Even though the recent technological advances have provided valuable support for people with disabilities, the focus has in most cases been placed on sensory and physical impairments, while IDD is normally not on the agenda of technology developers. In this paper, we will describe how the Able to Include project is changing this situation, using various Natural Language Processing (NLP) techniques. We will also describe how the pilot studies guide us in improving our tools.
