From Messy to Clean with Ontotext Refine

Exploring the new features of the Ontotext's tool for data wrangling, string splitting and triple spinning.

The recording of this webinar is available on YouTube.

From Messy to Clean with Ontotext Refine

Ontotext Refine (formerly OntoRefine) is an intuitive no-code tool to clean and transform data into structured RDF using a freely accessible visual mapping interface.

Ontotext Refine supports analyzing input data, applies data cleaning and transformation algorithms, maps string values into knowledge graph concepts, and imports the generated model into GraphDB. Based on the popular OpenRefine, it offers a visual RDF mapping interface with a command line tool to automate all steps and integration with secured GraphDB endpoints.

This webinar will be a demonstration of how to use Ontotext Refine to transform messy tabular data into clean and structured RDF data, presented by Nikola Tulechki, Knowledge Engineer & Data Scientist at Ontotext. He will first show the graphical interface to interactively clean, enrich and map sample data to RDF. Then, he will show how easy it is to turn the work into a batch job that can be executed using Ontotext Refine’s new command line interface on any input data of the same shape. Come and join him!
