The project consists in the construction of an RDF Knowledge Graph with RDFLib starting from tabular data. The data is about music.
The main task is to create a RDF Knowledge Graph that follows the next points:
- create an RDFLib Graph from data contained in CSV files,
- integrate the data with DBpedia’s,
- gathering information from unstructured data (Wikipedia),
- include a small ontology and a genres taxonomy,
- materialize inferences,
- query the Graph
- Knowledge Representation and Reasoning (KRR)
- Knowlegde Graph
- RDFLib
- RDF, RDFS
- OWL, OWLRL
- SPARQL
- DBpedia
- WikipediaAPI
Here we can have a quick look at the two starting CSV files. The albums, artists, genre, subgenre, ratings and reviews of these albums are our main topic in the knowledge graph.
