3arif: A Corpus of Modern Standard and Egyptian Arabic Tweets Annotated for Epistemic Modality Using Interactive Crowdsourcing

摘要

We present 3arif, a large-scale corpus of Modern Standard and Egyptian Arabic tweets annotated for epistemic modality. To create 3arif, we design an interactive crowdsourcing annotation procedure that splits up the annotation process into a series of simplified questions, dispenses with the requirement for expert linguistic knowledge and captures nested modality triggers and their attributes semi-automatically.
