# get_relation_cardinality_types_df

Determine the relation cardinality types.

The possible types are given in relation_cardinality_types.

Note

In the current implementation, we have by definition

$1 = \sum_{type} conf(relation, type)$

Note

These relation types are also mentioned in [wang2014]. However, the paper does not provide any details on their definition, nor is any code provided. Thus, their exact procedure is unknown and may not coincide with this implementation.

Parameters:
Return type:

DataFrame

Returns:

A dataframe with columns ( relation_id | relation_type )
