Entity graph

Above: “Entity graph” screenshot from mergeflow.net.

getEntityCooccurrenceGraph returns a set of nodes and edges. Each node has assigned an entity class and an ID. The edges reference these node IDs to connect two nodes. The weight refers to the number of documents (nodes) or the number of co-occurrences (edges) respectively.

Method call


Applicable parameters

q, date, sp, site, rows, tagcat, tagtype

The rows parameter is limited to a value of 500 rows per request (which is the recommended value). At least one entity class must be specified with the tagcat parameter to retrieve some data. Set tagtype=custom to include the search terms as nodes.

Sample result

Currently, the EntityClassDesc property of a node has a value assigned only if the node’s entity class is IPC (ID 20).
