Knowledge Graph Creation with Ontology Validation – 1-Day Project

I am looking for a skilled data scientist to create a comprehensive knowledge graph within 1 day and a maximum budget of 50 Euros. The project involves processing and extracting data from three CSV files and two JSON files to populate an ontology for advanced data analysis. Responsibilities include building the knowledge graph, enhancing it using SPARQL queries for meaningful insights, and defining at least five SHACL node shapes with a minimum of three property shapes each to validate the graph’s structure and integrity. Tools required for the project include OpenRefine, RML, RML Mapper, and YARRRML. Deliverables include a fully populated knowledge graph, a set of SHACL validation shapes, and a concise PDF report (maximum 10 pages) documenting the methodology, tools, results, and key insights. Applicants should have expertise in data analysis, knowledge graph creation, SPARQL, and experience with the specified tools, along with strong documentation and communication skills. If you can meet these requirements and deliver high-quality results within the given time and budget, I look forward to your application.
