Based on the given datasets, an ontology should be engineered, the data shall be integrated in a knowledge graph as well as the business questions should be answered from that graph.
Objectives
A company want to make their knowledge graph accessible via a SPARQL service.
The SPARQL service need to answer business questions, examples:
- Find related products (e.g. cluster by packaging size or weight)
- Find services / products without a product manager
- Find services / products without responsible department
- Identify alternative experts that can take over responsibility
Three datasets exists and these data have to be reusable in a knowledge graph accessible via a SPARQL service.
A XML file of an organisational structure of the client:
