Conversion factor Knowledge Graph
This repository contains the data cleaning steps and mappings of the conversion factor knowledge graph. At the moment, public data includes:
BEIS-UK, from years 2016-2022
- Data is licensed under an Open Government license
- Each data source used is linked in each conversion factor in the KG
Machine Learning impact calculator, from years 2002-2018
- Data is licensed under a MIT license
- Each data source used is linked in each conversion factor in the KG
Work in progress:
- EPA
Query interface
A derreferenceable linked data browser is available at: https://query.cf.linkeddata.es/query, based on https://github.com/TEC-Toolkit/rdf_explorer.
To see information about a conversion factor, just click on its URL, e.g., https://w3id.org/ecfkg/i/UK/BEIS/2021/CF_1.
SPARQL endpoint
All data is loaded in https://sparql.cf.linkeddata.es/cf, in the cf dataset. To perform a query, just URL encode the query:
sh
curl https://sparql.cf.linkeddata.es/cf -X POST --data 'query=YOUR_QUERY_URL_ENCODED' -H 'Accept: application/sparql-results+json,*/*;q=0.9'
For example, the following query retrieves the conversion factors that involve "Butane" (and their corresponding basic metadata)
SPARQL:
```sparql PREFIX ecfo: https://w3id.org/ecfo# PREFIX rdfs: http://www.w3.org/2000/01/rdf-schema#
SELECT ?cf ?source ?context ?target ?scope WHERE { ?cf ecfo:hasTag/rdfs:label "Butane"@en. ?cf ecfo:hasEmissionTarget/rdfs:label ?target. ?cf ecfo:hasEmissionSource/rdfs:label ?source. ?cf ecfo:hasAdditionalContext ?context. ?cf ecfo:hasScope ?scope. } ```
Corresponding curl command:
sh
curl https://sparql.cf.linkeddata.es/cf -X POST --data 'query=PREFIX+ecfo%3A+%3Chttps%3A%2F%2Fw3id.org%2Fecfo%23%3E%0APREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0A%0Aselect++%3Fcf+%3Fsource+%3Fcontext+%3Ftarget+%3Fscope+where%7B%0A++++%3Fcf+ecfo%3AhasTag%2Frdfs%3Alabel+%22Butane%22%40en.%0A++++%3Fcf+ecfo%3AhasEmissionTarget%2Frdfs%3Alabel+%3Ftarget.%0A++++%3Fcf+ecfo%3AhasEmissionSource%2Frdfs%3Alabel+%3Fsource.%0A++++%3Fcf+ecfo%3AhasAdditionalContext+%3Fcontext.%0A++++%3Fcf+ecfo%3AhasScope+%3Fscope.%0A%7D' -H 'Accept: application/sparql-results+json,*/*;q=0.9'
Tutorial
Have a look at our tutorial, showing how to plot the evolution of a conversion factor through the years, together with the corresponding SPARQL queries needed to adapt it to your own.
