Bringing Structure into Summaries: Crowdsourcing a Benchmark Corpus of Concept Maps
Tobias Falke, Iryna Gurevych · 2017
Concept maps can be used to concisely represent important information and bring structure into large document collections.Therefore, we study a variant of multidocument summarization that produces summaries in the form of concept maps.However, suitable evaluation datasets for this task are currently missing.To close this gap, we present a newly created corpus of concept maps that summarize heterogeneous collections of web documents on educational topics.It was created using a novel crowdsourcing approach that allows us to efficiently determine important elements in large document collections.We release the corpus along with a baseline system and proposed evaluation protocol to enable further research on this variant of summarization. 1
