Ego Networks: ‘Pogi,’ ‘Kuya,’ ‘Sexy’ and ‘Tanda’

The visualizations here are inspired by the following news articles that link Ramon B. Revilla, Jr., Juan Ponce Enrile, and Jinggoy Ejercito Estrada to Napoles NGOs and notebooks: read this (Whistle-blowers bare Napoles pork records), this (Bong, JPE, Jinggoy ‘suki’ to Napoles NGOs), and this (Enrile, Estrada, Revilla linked anew to Napoles pork scam). Kindly note that the visualizations provided below do not put forth any additional insights that have not been presented yet to the public in the reports written on the subject matter (kindly refer to the articles provided). The graphs are created as schematic diagrams — to make the information more pleasing to the eyes and palatable to those who are too lazy busy to read on the topic.

Data visualization or data visualisation is the study of the visual representation of data, meaning “information that has been abstracted in some schematic form, including attributes or variables for the units of information”.

In a previous post, a network visualization of the NGO-legislator relationships was constructed from the table provided in Annex A of the Special Audit Report of COA (for CY 2007-2009). The resulting network is a bipartite network (a network with two types of nodes).

The full bipartite network generated from Annex A of the SAO report by the COA. The red nodes represent NGO-nodes, while the blue nodes represent Legislator-nodes. The size of the nodes show the total amount associated to the nodes.

A network has, in general, two elements: the Nodes and the Edges (links). The nodes represent the entities in the set, while the edges represent relationships. Having a network visualisation can help highlight interesting patterns within a dataset. What I have set up in this post is a bipartite network — a network with two (2) types of nodes: NGO (red nodes) and Legislator (blue nodes). A link is drawn between an NGO-node and a Legislator-node if they are “involved” in the same project. – Network Patterns in Pork

Using the same network, a union of filtered ego network was extracted from the full network using three “ego” nodes (or three focal nodes) namely: Ramon B. Revilla, Jr., Juan Ponce Enrile, and Jinggoy Ejercito Estrada.

Ego networks consist of a focal node (“ego”) and the nodes to whom ego is directly connected to (these are called “alters”) plus the ties, if any, among the alters.

The resulting filtered network is shown below.

In the Rappler news report titled “Bong, JPE, Jinggoy ‘suki’ to Napoles NGOs,” a “list of all Napoles-linked NGOs that COA found” is provided. A snapshot of the list is provided below.

Incorporating this information in the union network of ego networks above, we have

Union networks of ego networks highlighting “Napoles-controlled” NGO’s.

To those who are interested in seeing who the other legislators who funnelled funds in these NGOs where the trio are linked are, a union network of the three ego networks (of depth 2) is provided.

A union network of three ego networks of depth equal to 2:  include other legislators  linked to the NGOs linked to focal nodes.
