Graph

KGX makes use of an in-memory labelled property graph for representing a Knowledge Graph.

To support a wide variety of graph libraries, KGX has a Graph API which abstracts over the underlying graph store.

Should you want to add support for a new graph store,

  • create a new class that extends kgx.graph.base_graph.BaseGraph.
  • modify the graph_store variable in kgx/config.yml.

kgx.graph.base_graph.BaseGraph

BaseGraph is the base Graph API that can be used to abstract over any graph, as long as the graph is capable of successfully representing a property graph.

.. automodule:: kgx.graph.base_graph
   :members:
   :inherited-members:
   :show-inheritance:

kgx.graph.nx_graph.NxGraph

NxGraph is basically an abstraction on top of networkx.MultiDiGraph.

The NxGraph subclasses kgx.graph.base_graph.BaseGraph and implements all the methods defined in BaseGraph.

.. automodule:: kgx.graph.nx_graph
   :members:
   :inherited-members:
   :show-inheritance:
