  We present Etymo (https://etymo.io), a discovery engine to facilitate
artificial intelligence (AI) research and development. It aims to help readers
navigate a large number of AI-related papers published every week by using a
novel form of search that finds relevant papers and displays related papers in
a graphical interface. Etymo constructs and maintains an adaptive
similarity-based network of research papers as an all-purpose knowledge graph
for ranking, recommendation, and visualisation. The network is constantly
evolving and can learn from user feedback to adjust itself.
