GitMA Network#
Note
This class is integrated in the CatmaProject
and AnnotationCollection
class.
See the examples in the introduction.
- class Network(annotation_collections, character_distance=100, edge_func='cooccurrent', included_tags=None, excluded_tags=None, level='tag', network_layout=<function kamada_kawai_layout>)#
Bases:
object
Class to draw annotation coocurrence network graphs.
- Parameters
annotation_collections (List[AnnotationCollection]) – List of included annotation collections.
character_distance (int, optional) – Cooccurrence span. Defaults to 100.
edge_func (str, optional) – Keyword for the function that identifies connected annotations. Either
'cooccurent'
or'overlapping'
. Defaults to cooccurrent_annotations.included_tags (list, optional) – Included tags. If
None
and excluded_tagsNone
all tags are included. Defaults to None.excluded_tags (list, optional) – Excluded tags. Defaults to None.
level (str, optional) – Whether the annotations tag or the values of the given property gets included.
network_layout (callable, optional) – NetworkX Drawing Layout. Defaults to nx.drawing.layout.kamada_kawai_layout.
- edge_func: callable#
The edge function.
- level: str#
The annotation level.
- df: pandas.core.frame.DataFrame#
Merged annotations dataframe
- edges: List[gitma._network.Edge]#
List of edge objects.
- network_graph: networkx.classes.graph.Graph#

- pos: dict#
The node position
- to_gexf(filename='catma_network', directory='./')#
Writes Network Graph to a GEPHI xml file.
- Parameters
filename (str, optional) – The name of the gexf file. Defaults to ‘catma_network’.
directory (str, optional) – The file’s directory. Defaults to ‘./’.
- stats()#
Creates network stats data frame.
- Returns
degree, weighted_degree, betweenness centrality, weighted betweenness centrality
- Return type
pd.DataFrame
- plot(node_size='weighted_degree', node_factor=100.0, node_alpha=15, plot_stats=False)#
Plots network as plotly graph.
- Parameters
