The hephaistos toolkit consists of loosely coupled tools for Knowledge Graph Construction (KGC), Human-in-the-Loop (HumL) integration and evaluation (Eval). Tools are designed with a certain user group in mind, namely knowledge engineers (KE), non-technical users (NTU), developers (Dev) and Semantic Web practitioners (SW). They can be applied before, during or after the main construction phase. Some of them are ready to use (live), others need some effort to be usable (recoverable) and few are closed source or are discontinued. If available, links to a demo, the codebase and the research paper are provided.
