Phone communication data Phone communication data from multiple phone extractions. The file NodeList.csv contains the nodes of the multivariate graph and contains the following columns: _nodeID : unique identifier for each entity of the graph _nodeType : specification of node type (phone, person, contact or identifier) _viewIcon: tulip-specific attribute which defines the icon used for each node _viewShape: tulip-specific attribute which defines the shape for each node The file EdgeList.csv contains all edges between the above specified nodes and contains the following columns: _sourceID : unique identifier of source node _targetID : unique identifier of target node _relType : specification of the type of relation (communication, contact association, user account association) _nbCommunications : number of communications exchanged between two given nodes. Attribute present only for edges of type ‘communication’. Nodes and relations can be imported into Tulip using the ‘import csv’ option. In order to create metanodes, only edges describing associations (contacts, user accounts) are used in a first step in order to use the algorithm ‘connected componants’. After importing the communication edges, metanodes can then be created based on the metric value calculated beforehand.
