ABSTRACT

Using network theory, the researchers visualize and analyze relationships that can be found in the Priority Development Assistance Fund (PDAF) allocation from the released 2012 report of the Commission of Audit (COA). Strong community structure was seen in the legislator-legislator co-funding network and NGO-NGO co-funding network as indicated by the high values of modularity, 0.5 and 0.4 respectively. Also, communities in the legislator-legislator network do not correspond to parties but they do try to incorporate members of the ruling party.

 

INTRODUCTION

Various systems in nature are driven by mechanisms with non-trivial interactions. From language (Roxas & Tapang 2010) to politics (Zhang et al. 2008), these systems are highly complex with behaviors that are hard to predict. However, these systems are still of interest to us, so their analysis has driven the development of new methods. One possible method is to study the small-scale interactions between the individual elements along with their patterns and structure. The researchers want to see if these patterns and structures reflect real properties of the system. This is the basis of using network science to analyze systems.
A network is a simple way to represent a set of objects or nodes that have relationships with each other. These objects are called nodes or vertices, while call the relationship between them is called an edge (Barrat et al. 2008). Depending on the data set, edges could represent different kinds of relationships. In a social network, these could be friendship relations (Wang & Wellman 2010) or co-authorships in a congressional setting (Fowler 2006). Edges in networks can have values attached to them (weighted networks) or be set to have a uniform weight of one for unweighted networks (Barrat et al. 2008). . . . . read more
