RepGraph: Visualising and Analysing Meaning Representation Graphs
Jaron Cohen, Roy Cohen, Edan Toledo, Jan Buys · 2021
We present RepGraph, an open source visualisation and analysis tool for meaning representation graphs.Graph-based meaning representations provide rich semantic annotations, but visualising them clearly is more challenging than for fully lexicalized representations.Our application provides a seamless, unifying interface with which to visualise, manipulate and analyse semantically parsed graph data represented in a JSON-based serialisation format.RepGraph visualises graphs in multiple formats, with an emphasis on showing the relation between nodes and their corresponding token spans, whilst keeping the representation compact.Additionally, the web-based tool provides NLP researchers with a clear, visually intuitive way of interacting with these graphs, and includes a number of graph analysis features.The tool currently supports the DMRS, EDS, PTG, UCCA, and AMR semantic frameworks.A live demo is available at https://repgraph.vercel.app/.
