ink.base.graph.KnowledgeGraph

class ink.base.graph.KnowledgeGraph(connector, prefixes=None, extract_inverse=False)

Bases: object

Knowledge graph class representation

This graph builds and stores the internal knowledge graph representations. It stores and builds the neighborhoods of the nodes of interest through the initialized connector.

Parameters

  • connector (ink.base.connectors.AbstractConnector) – Connector instance.

  • prefixes (list) – Optional dictionary of prefixes which should be mapped.

__init__(connector, prefixes=None, extract_inverse=False)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(connector[, prefixes, extract_inverse])

Initialize self.

extract_neighborhoods(data, depth[, …])

Function which extracts all the neighborhoods of a given set of nodes of interest.

neighborhood_request(noi)

Function to make a neighborhood request of a certain instance.
extract_neighborhoods(data, depth, skip_list=None, verbose=False, jobs=1)

Function which extracts all the neighborhoods of a given set of nodes of interest.

Parameters

  • data (list) – List of node of interests.

  • depth (int) – The maximum depth of the neighborhood.

  • skip_list (list) – List with relations which are not taken into account when traversing the neighborhoods.

  • verbose (bool) – Parameter to show tqdm tracker (default False).

Returns

List of dictionaries containing the neighborhood until the defined depth for each instance of the dataset.

Return type

list

neighborhood_request(noi)

Function to make a neighborhood request of a certain instance.

Parameters

noi (str) – URI of Node Of Interest (noi).

Returns

Dictionary with all values specified as in the connector string.

Return type

dict
