A Search Engine for Discovery of Scientific Challenges and Directions. (arXiv:2108.13751v3 [cs.CL] UPDATED)

Keeping track of scientific challenges, advances and emerging directions is a
fundamental part of research. However, researchers face a flood of papers that
hinders discovery of important knowledge. In biomedicine, this directly impacts
human lives. To address this problem, we present a novel task of extraction and
search of scientific challenges and directions, to facilitate rapid knowledge
discovery. We construct and release an expert-annotated corpus of texts sampled
from full-length papers, labeled with novel semantic categories that generalize
across many …
