What tools are you using to build and visualize knowledge graphs in 2020?
I would also be interested in the use cases that justify the usage of KGs in your work.
Also, it would be interesting to know if anyone is using KGs for feature engineering in Machine Learning and how that is working out.
Not using KGs for feature engineering/machine learning, but more for (personal) knowledge management. Using my own open source tool, Contextualise (https://contextualise.dev/ and https://github.com/brettkromkamp/contextualise). Check out the awesome-knowledge-management list for more KG and KM resources: https://github.com/brettkromkamp/awesome-knowledge-managemen...
At a professional level use KGs for educational web services in relation to curricula taxonomies.
