Long Input Dialogue Summarization with Sketch Supervision for Summarization of Primetime Television Transcripts 

This paper presents our entry to the CreativeSumm 2022 shared task, tackling the problem of prime-time television screenplay summarization based on the SummScreen Forever Dreaming dataset. Our approach utilizes extended Longformers combined with sketch supervision including categories specifically for scene descriptions. Our system was able to produce the shortest summaries out of all submissions. While some problems with factual consistency still remain, the system was scoring highest among competitors in the ROUGE and BERTScore evaluation categories.
