Ontotext Refine description from the product owner, Nikola Tulechki.
Ontotext Refine is a free application for automating the conversion of messy string data into a knowledge graph. It is built for data engineers and subject matter experts who need to explore, clean and understand their data and then quickly map and transform any structured data to RDF schema.
The tool supports analyzing the input data, applies various data cleaning and transformation algorithms, maps the string values into knowledge graph concepts and imports the generated model into GraphDB.
The application is based on the popular OpenRefine tool and includes a visual RDF mapping interface, a command line tool to automate all steps and integration with secured GraphDB endpoints.
