GrapAL: Connecting the Dots in Scientific Literature
Christine M. Betts, Joanna Power, Waleed Ammar · 2019
We introduce GrapAL (Graph database of Academic Literature), a versatile tool for exploring and investigating a knowledge base of scientific literature that was semiautomatically constructed using NLP methods.GrapAL fills many informational needs expressed by researchers.At the core of Gra-pAL is a Neo4j graph database with an intuitive schema and a simple query language.In this paper, we describe the basic elements of GrapAL, how to use it, and several use cases such as finding experts on a given topic for peer reviewing, discovering indirect connections between biomedical entities, and computing citation-based metrics.We open source the demo code to help other researchers develop applications that build on GrapAL. 1
