kgheartbeat 0.2.4

Library that allows to perform Knowledge Graph (Linked Open Data) quality analysis.

KGHeartbeat API

Library that allows you to perform Knowledge Graph (Linked Open Data) quality analysis.

Installation

pip install kgheartbeat

Calculate the Availability dimension

from kgheartbeat import KnowledgeGraph

# Instanziate a KnowledgeGraph class, passing the id of the kg to be analyzed
kg = KnowledgeGraph('dbpedia')

# Check the SPARQL endpoint availability
sparqlAv = kg.checkEndpointAv()
# Check if the links for download the dataset is up
checkDump = kg.checkDownload()
# Check if there are any inactive links
inactiveLks = kg.checkInactiveLinks()
# Calculate the URI's deferenceability (based on 5000 randomly recoverable uri). THIS COULD TAKE TIME, DEPENDS ON THE SPEED OF THE ENDPOINT (~45 min. for DBpedia)
uriDef = kg.getURIsDef()

#Print all the results
print(f"SPARQL endpoint availability: {sparqlAv}\n \
       RDF dump link availability: {checkDump}\n\
       Any inactive links: {inactiveLks}\n\
       URIs deferenceability: {uriDef}")

Calculate the Licensing dimension

from kgheartbeat import KnowledgeGraph

# Instanziate a KnowledgeGraph class, passing the id of the kg to be analyzed
kg = KnowledgeGraph('taxref-ld')

#Search for the machine-redeable license
mr_license = kg.getLicenseMR()
#Search for a human-redeable license
hr_license = kg.getLicenseHR()

print(f"Machine redeable license: {mr_license}\nHuman-redeable license: {hr_license}")

Calcuate the Versatility dimension

# Instanziate a KnowledgeGraph class, passing the id of the kg to be analyzed
kg = KnowledgeGraph('bncf-ns')

#Find the different serialization formats available (e.g. .rdf, .n3, .xml)
formats = kg.getSerializationFormat()
#Get languages if is indicated
languages = kg.getLanguages()
#get all the links to access the KG
link_access = kg.getAccessAtKG()

print(f"Serialization formats: {formats}\nLanguages: {languages}\n Link to access the KG:{link_access}\n")
