Abstractive summarization of line graphs from popular media

Information graphics (bar charts, line graphs, etc.) in popular media generally have a discourse goal that contributes to achieving the communicative intent of a multimodal document. This paper presents our work on abstractive summarization of line graphs. Our methodology involves hypothesizing the intended message of a line graph and using it as the core of a summary of the graphic. This core is then augmented with salient propositions that elaborate on the intended message.
