Ambiverse - an amazing open-source suite for natural language understanding

While doing performance benchmarks for Named Entity Linking solutions for our AI/FinTech start-up Risklio, I stumbled upon a very powerful, only just open-sourced framework called AmbiverseNLU. It was developed by Ambiverse and is based on work previously done at the Max Planck Institute¹. The components it uses are more well-known: entity recognition from KnowNER², open information extraction using ClausIE³ and AIDA, an entity detection and disambiguation tool⁴. You can have a look at the demo here. For the former one you can choose whether to use Apache Cassandra or PostgreSQL as a backend, while the last one uses Neo4j.
