LibraryEvaMap

A python library that can assess the quality of an RDF mapping.

Installation

Installation in a virtualenv is recommended.

Assuming you already have python 3 and pip installed

pip install EvaMap

Initialize EvaMap

First, instantiation of an EvaMap object takes three parameters:

1. rdf_ontology: The ontology used in the yarrrml_mapping in RDF (turtle, xml or n3)
2. yarrrml_mapping: The RDF mapping of the json_data in YARRRML
3. json_data: The dataset in JSON format

from EvaMap.EvaMap import EvaMap

evamap = EvaMap(rdf_ontology, yarrrml_mapping, json_data)

Assess the mapping

You can assess the quality of the yarrrml_mapping by using the evaluate_mapping method:

evamap.evaluate_mapping()

Retrieve results

After evaluation, you can retrieve the total score of the yarrrml_mapping with get_total_score() method:

evamap.get_total_score() # e.g., 0.6805555555555557

or, a list of Dict representing score for each dimensions, metrics and feedbacks with get_complet_result() method:

evamap.get_complet_result()
