Cohesion analysis (also called structural cohesion) is often used to explain and develop sociological theories. Members of a cohesive subgroup tend to share information, have homogeneity of thought, identity, beliefs, behavior, even food habits and illnesses (Wasserman, S., Faust, K, 1994). Cohesion analysis is also believed to influence emergence of consensus among group members.

After tragic terrorist attacks by kidnapped airlines on New York and Washington in September 2001 the interest for Al Qaeda in public and media rose immediately. Experts and analysts all over the world started to offer various explanations of Al Qaeda’s origins, membership recruitment, modes of operation, as well as of possible ways of its disruption. Journalists in search of hot topics took over and publicized most of the publicly available materials, often revising them further and making them even more exciting and attractive for wide audiences.

One could thus read or hear that Al Qaeda is “a net that contains independent intelligence”, that it “functions as a swarm”, that it “gathers from nowhere and disappears after action”, that it is “an ad hoc network”, “an atypical organization” (Memon N., H. L. Larsen, 2006), extremely hard to destroy, especially by traditional anti-terrorist / counterterrorist methods.

According to many counterterrorism analysts today, Al Qaeda has evolved from a centrally directed organization into a worldwide franchiser of terrorist attacks (Grier P., 2005). Since war in Afghanistan, which significantly degraded Osama bin Laden’s command and control, Al Qaeda does appear to have become increasingly decentralized. It is now seen by many as more of a social movement than coherent organization (Wikotorowicz Q., 2001).

Al Qaeda did not decide to decentralize until 2002, following the ouster of the Taliban from Afghanistan and the arrest of a number of key Al Qaeda leaders including Abu Zubaydhah, Al Qaeda’s Dean of students, Ramzi bin Al Shibh, the organizer of the Hamburg cell of 9/11 hijackers, Khalid Sheikh Mohammed, the mastermind of 9/11 and the financier of the first World Trade Center attack, and Tawfiq Attash Kallad, the master mind of the USS Cole attack.

In response these and other key losses, Al Qaeda allegedly convened a strategic summit in northern Iran in November 2002, at which the group’s consultative council decided that it could no longer operate as a hierarchy, but instead would have to decentralize (Joseph Felter et. al., 2005).

[page 8]

According to most counterterrorism analysts today, al-Qa’ida has evolved from a centrally directed organization into a worldwide franchiser of terrorist attacks.7 Indeed, since the war in Afghanistan, which significantly degraded bin Laden’s command and control, al-Qa’ida has become increasingly decentralized, and is seen by some as more of a “movement” than any other form of organization.

[page 9]

In 2001, following the ouster of the Taliban from Afghanistan, a number of al-Qa’ida leaders suddenly found themselves in detention centers facing long months of interrogation. Abu Zubaydah, al-Qa’ida’s “dean of students,” who directed training and placement for the group, was captured in Faisalabad, Pakistan, in February 2002. Ramzi Bin al Shibh, the organizer of the Hamburg, Germany cell that formed the core of the 9/11 hijackers, was captured in Karachi, Pakistan, on the first anniversary of the attacks. These and other counterterrorism successes ultimately led to the capture of Khalid Sheik Mohammed, the mastermind of 9/11 and the financier of the first World Trade Center attack, in Rawalpindi, Pakistan, in March 2003. And a month later, Tawfiq Attash Kallad, the mastermind of the USS Cole attack, was apprehended in Karachi. In response to the loss of key leaders, al-Qa’ida allegedly convened a strategic summit in northern Iran in November 2002, at which the group’s consultative council came to recognize that it could no longer exist as a hierarchy, but instead would have to become a decentralized network and move its operations out over the entire world.10

The method focuses on uncovering the patterning of people’s interaction, and correctly interpreting these networks assists “in predicting behaviour and decision-making within the network”.

The method also endows the analyst the ability to measure the level of covertness and efficiency of the cell as a whole, and also the level of activity, ability to access others, and the level of control over a network each individual possesses. The measurement of these criteria allows specific counter-terrorism applications to be drawn, and assists in the assessment of the most effective methods of disrupting and neutralising a terrorist cell. In short IDM “provides a useful way of structuring knowledge and framing further research. Ideally it can also enhance an analyst’s predictive capability”.

Covert networks like terrorist networks remain mingled with socially oriented networks (like families, organizations etc.) in the real world. The buzz word for covert networks is “secrecy” and hence to discover such networks (technically, to discern distinctive patterns in the activities and communications of such dark networks) can be very tricky and often misleading due to unavailability of authentic data or in some cases availability of “doctored” data. This issue has especially blown up in the recent past and after the September 11, 2001 tragedy, it has been in the limelight so much so that it is worthwhile to take a close look at the distinguishing properties of such networks. For Example:

(1) In bright networks, actors who are highly central are typically the most important ones. On the contrary, peripheral players (or “boundary spanners” as they are typically called) may be huge resources to a terrorist group although they receive very low network centrality scores. This is because they are well positioned to be innovators, since they have access to ideas and information flowing in other clusters. Similarly, in an organization, these peripheral employees are in a position to combine different ideas and knowledge into new products and services. They may be contractors or vendors who have their own network outside of the company, making them very important resources for fresh information not available inside the company (Krebs V., 2002, Hanneman, R., 2000).

(2) The role of a “broker” (Krebs V., 2002) is a very powerful role in a social network as it ties two hitherto unconnected constituencies / groups together but of course, it is a single-point of failure. These broker type roles are often seen in terrorist networks. Such nodes are also referred to as “cutpoints” (Hanneman, R., 2000).

Modeling a cohesive subgroup mathematically has long been a subject of interest in social network analysis. One of the earliest graph models used for studying cohesive subgroups was the clique model (Luce, R., Perry A., 1949). A clique is a subgraph in which there is an edge between any two vertices. However, the clique approach has been criticized for its overly restrictive nature (Scott, J, 2000), Wasserman, S., Faust, K., 1994) and modeling disadvantages (Siedman [sic], S. B., Freeman, L. C., 1992).

Alternative approaches were suggested that essentially relaxed the definition of cliques. Clique models idealize three important structural properties that are expected of a cohesive subgroup, namely, familiarity (each vertex has many neighbors and only a few strangers in the group), reachability (a low diameter, facilitating fast communication between the group members) and robustness (high connectivity, making it difficult to destroy the group by removing members).

Different models relax different aspects of a cohesive subgroup. Luce R. introduced a distance based model called n-clique (Luce, R., 1950). This model was also studied along with a variant called n-clan by Mokken (Mokken, R., 1979).

However, their originally proposed definitions required some modifications to be more meaningful mathematically.

These drawbacks are pointed out and the models are appropriately redefined in (Balasundaram, B. et al, 2005). All these models emphasize the need for high reachability inside a cohesive subgroup and have their own merits and demerits as models of cohesiveness. In this paper we also discuss on a degree based model and called k-plex (Wasserman, S. et al, 2004). This model relaxes familiarity within a cohesive subgroup and implicitly provides reachability and robustness. These drawbacks are pointed out and the models are appropriately redefined in [7], as described in Section 2. All these models emphasize the need for high reachability inside a cohesive subgroup and have their own merits and demerits as models of cohesiveness.

The main idea is to use as a measure of the centrality of a node i the drop in the network efficiency caused by deactivation of the node. The importance I (nodei) of the ith [sic] node of the graph G is therefore:

I (nodei) ≡ Δ E = E (G) − E (G − nodei) , i = 1,...,N, (2)

Where G − nodei indicates the network obtained by deactivating nodei in the graph G. The most important nodes, i.e. the critical nodes are the ones causing the highest ΔE.

The centrality measures address the question, “Who is the most important or central person in the network?” There are many answers to this question, depending on what we mean by important. Perhaps the simplest of centrality measures is degree centrality, also called simply degree.

Though simple, degree is often a highly effective measure of the influence or importance of a node: in many social settings people with more connections tend to have more power.

A more sophisticated version of the same idea is the so-called eigenvector centrality (which is also known as centrality of a centrality). Where degree centrality gives a [simple count of the number of connections a vertex has, eigenvector centrality acknowledges that not all connections are equal.]
