Welcome to Graph Data Science: https://derwen.ai/docs/kgl/

The kglab library provides a simple abstraction layer in Python 3.7+ for building knowledge graphs, leveraging Pandas, NetworkX, RAPIDS, RDFLib, Morph-KGC, pythonPSL, and many more.

SPECIAL REQUEST:
Which features would you like in an open source Python library for building knowledge graphs?
Please add your suggestions through this survey:
https://forms.gle/FMHgtmxHYWocprMn6
This will help us prioritize the kglab roadmap.

"Feels like it's a Hugging Face for graphs! 🤯"

See the "Getting Started" section of the online documentation.

We recommend installing from PyPi or conda:

python3 -m pip install kglab

pipenv install kglab

conda env create -n kglab
conda activate kglab
pip install kglab

If you work directly from this Git repo, be sure to install the dependencies:

python3 -m pip install -U pip wheel
python3 -m pip install -r requirements.txt

pipenv install --dev

Alternatively, to install dependencies using conda:

conda env create -f environment.yml --force
conda activate kglab

Then to run some simple uses of this library:

import kglab

# create a KnowledgeGraph object
kg = kglab.KnowledgeGraph()

# load RDF from a URL
kg.load_rdf("https://bigasterisk.com/foaf.rdf", format="xml")

# measure the graph
measure = kglab.Measure()
measure.measure_graph(kg)

print("edges: {}\n".format(measure.get_edge_count()))
print("nodes: {}\n".format(measure.get_node_count()))

# serialize as a string in "Turtle" TTL format
ttl = kg.save_rdf_text()
print(ttl)

See the tutorial notebooks in the examples subdirectory for sample code and patterns to use in integrating kglab with other graph libraries in Python: https://derwen.ai/docs/kgl/tutorial/

WARNING when installing in an existing environment:
Installing a new package in an existing environment may reveal
or create version conflicts. See the kglab requirements
in requirements.txt before you do. For example, there are
known version conflicts regarding NumPy (>= 1.19.4) and TensorFlow 2+ (~-1.19.2)

docker build --pull --rm -f "docker/Dockerfile" -t kglab:latest .
docker run -p 8888:8888 -it kglab

docker build --pull --rm -f "docker/testsuite.Dockerfile" -t kglabtest:latest .
docker run --rm -it kglabtest
