SPARQL Queries: Molecular Entities as Structured Data on the Web

Queries allow discovering new knowledge from data. In addition, queries can combine existing data with data obtained from other sources.

The dataset includes seven SPARQL queries (Queries directory) and results (Results directory). The queries were made using Apache Fuseki and Rasqal on the chemical molecules datasets DS1, DS2, DS3, DS4, and DS5 published at https://data.mendeley.com/datasets/n9xwfs5fcj/1. The mentioned datasets contain molecules described in structural data formats (JSON-LD, RDFa, and Microdata).
