Requirements Analysis for an Open Research Knowledge Graph [article]

Arthur Brack, Anett Hoppe, Markus Stocker, Sören Auer, Ralph Ewerth
2020 arXiv   pre-print
Recently, several initiatives have proposed knowledge graphs (KGs) for organising scientific information as a solution to many of the current issues.  ...  In this paper, we aim to transcend this limited perspective by presenting a comprehensive analysis of requirements for an Open Research Knowledge Graph (ORKG) by (a) collecting daily core tasks of a scientist  ...  However, semantic search engines employ latent representations of KGs and text (e.g. graph and word embeddings) [6] .  ...
