We designed an input dialogue to collect the disability information of learners. The learners are supposed to enter their proﬁle information, which could also be automatically inferred from the context in parts. The form of the input dialogue is generated from our AccessibleOCW ontology using SPARQL queries. It asks the learners to input their disabilities, available devices, and personal preferences.
We used SPARQL to query the ontology, using Fuseki as the SPARQL server. We created a SPARQL client in React that accesses our ontology on the Fuseki server.
