SNA and "Clout Rank Algorithm" #SNA-ONA-VNA
Bruce Karney <bkarney@...>
The recent post about SNA at Braintrust spurred this train of though.
Many of us have heard about Google's Page Rank Algorithm. It has grown in complexity over time, but the basic idea has been explained to me as: The rank (or importance) of a web page is based on the NUMBER of other pages that link to it, and the rank of those pages. So, if I create a new web page and only one other page points to mine, the rank of my page depends on how many OTHER pages link to the page that points to mine. That seems reasonable and straightforward. This simple insight has created several hundred Google millionaires in Silicon Valley. My question: does anyone know of a Clout Rank Algorithm that measures a person's ability to exercise "clout" through their social network? Wouldn't such a measure work similarly to Page Ranking? At an extreme, if you were to discover that you were on a subway train suffering from amnesia, knowing no one, you would have zero clout. But if you were Jack Welch or Tony Blair, with thousands of friends and acquaintances, many of them powerful, you would have vast amounts of clout. Has anyone ever managed to construct a quantitative model of this? Would such models provide value to individuals or to businesses? Could a conscious process of trying to acquire more clout be morally positive, if one's intention was to use that clout to improve the world, or are attempts to accumulate clout almost always simply social climing? (By the way, I get the impression from Bill and Melinda Gates recent interest in medical philanthropy that he has been deploying his enormous clout in VERY positive ways.) I'd love to hear from anyone with thoughts to share on this topic. Cheers, Bruce Karney bkarney@... 650-964-3567 (Pacific Time Zone home #) |

Is there a Clout Rank in SNA?

Yes. Depending on which SNA camp you follow, it's viewed a few different ways, but you can very quickly spot the highly connected people (hubs). This level of connectivity can be calculated as degree centrality, but on first pass it is related to how many direct connections a person has. It's a number that says, on average, how close are people in the network. The lower the number, the more direct connections a node has. But you can quickly imagine that a highly-connected person isn't terribly important if all the people in that network are also highly interconnected amongst themselves. (I believe this is something that Google checks for as well - self-referential pages aren't as highly ranked.) So the next thing to look for are nodes that lie between groups of nodes. They may not have as many connections, but they may create connections between important subnetworks. There is also a measure for this, "betweenness." The higher it is, the more brokering power that node has. Finally, you could ask how close is a node to the entire network, which is a similar measure to degree. The results vary, depending on the topography of the network. Closeness looks at how quickly one could communicate with the entire network, rather than the average separation. The result is that less heavily-connected nodes might actually be closer overall. Regards, Jack Vinson, Ph.D. Knowledge Jolt, Inc. http://www.jackvinson.com -----Original Message-----

and just to continue my "the emperor has no clothes" role. The minute you make an SNA result visible, then the criteria are explicit and the system will be gamed. In my view SNA between individuals (i) breaks all ethical standards and/or (ii) cannot be trusted as anything explicit will be gamed.

Google is based on a social network archetype called prestige. It is a SNA concept surfaced in the first-half of 20th Century. It is based on studies of baboons. Brin/Page built Google on this principle, among others. The rest is history. There is a lot of info available for both. There are more billion-dollar companies yet to be released by S/VNA. 'The Bible': http://tinyurl.com/eh3zc 'The Paper': http://tinyurl.com/f2bbp SNA/VNA: http://kmblogs.com/public/item/115274 VN/VNA is a mainstay of KM excellence. In OSI reference parlance SNA/ONA is the physical, data link layers (the knowledge pathways) and VNA is the application layer or business layer (the ecomonic 'whole system'). These 'economic value networks' (EVN) are critical for knowledge-based organizations. They are a topic of active research in our own backyard, by board-mates and colleagues, e.g., "2. Funded by the Bechtel Initiative at Stanford University, I am conducting a project entitled "The Networks of Silicon Valley". Though everyone agrees that the most crucial aspect of Silicon Valley's dramatic success is its networks, there has been virtually no systematic study of their history, structure and functioning. In this project, we propose to map these networks and their evolution over time. Using relational database methods developed in our study of the electricity industry, we will track the affiliation of company principals, trace the "genealogies" of new firms, and show how movements of people among firms continuously shapes and reshapes networks of both individuals and organizations. We also intend to study the institutional complex that supports local industrial activity, including financial, educational, legal, and political sectors. We hope that the end result will be the first comprehensive sociological account of an "industrial district." (Mark Graonovetter, Joan Butler Ford Professor, School of Humanities and Sciences, Chair, Department of Sociology, Stanford University) Also see: http://kmblogs.com/public/item/117131 The SF/Silicon Valley EVN conversations commence April 7, 2006 at UCSF.
