analyzing the connections between friends and followers INFOGRAPHIC: The state of broadband Internet worldwide - Technology - GMANews.TV - Official Website of GMA News and Public Affairs - Latest Philippine News In terms of average Internet broadband download speed alone, the Philippines lags behind roughly two-thirds of the world. The country is bested not just by world superpowers such as China and the US, it is also surpassed by small countries such as Lithuania and Kenya. The Philippines ranks 139 out of 185 countries. Why does this matter? Access to affordable high-speed Internet is a key to economic growth and job creation in developing countries, according to the World Bank. The Bank found that "for every 10 percentage-point increase in high-speed Internet connections there is an increase in economic growth of 1.3 percentage points." That could mean that laggard nations that quickly build capacity for broadband can swiftly catch up with others, and that the Philippines could be missing another opportunity to create more jobs and keep its talented workers home. The Philippines also has a long way to go in terms of Internet penetration. You can view the raw collated data here.
Small-world network Small-world network exampleHubs are bigger than other nodes Average vertex degree = 1,917 Average shortest path length = 1.803. Clusterization coefficient = 0.522 Random graph Average vertex degree = 1,417 Average shortest path length = 2.109. Clusterization coefficient = 0.167 In the context of a social network, this results in the small world phenomenon of strangers being linked by a mutual acquaintance. Many empirical graphs are well-modeled by small-world networks. Properties of small-world networks[edit] This property is often analyzed by considering the fraction of nodes in the network that have a particular number of connections going into them (the degree distribution of the network). ) is defined as R. Examples of small-world networks[edit] Examples of non-small-world networks[edit] Networks are less likely to have the small-world properties if links between nodes arise mainly from spatial or temporal proximity, because there may be no short path between two "distant" nodes.
Chicago Lobbyists Force-Directed Graph Visualization Created by Christopher Manning Summary This visualization includes the 50 highest paid lobbyists in Chicago, their clients, and the agencies they lobby. The data was compiled from ChicagoLobbyists.org in 2010. Blue Nodes: LobbyistsGrey Nodes: ClientsGreen Nodes: Agencies The radius of the Blue(Lobbyist) and Grey(Client) nodes is relative to the amount of money associated with them. Nodes closer to the center have more connections than nodes on the outer edge. Controls Hover a node to highlight the connected nodes and show the names and dollar amounts associated to that node.

Gapminder: Unveiling the beauty of statistics for a fact based world view. Connected: The Power of Six Degrees A very rich documentary about the new science of network. It is built around reproducing the “Six degrees of separation” experience. The main concepts are well explained and the history of discoveries is emphasized with many examples and interviews of the researchers. I personally think the documentary is well realized and may be understood by any public. The first part is about small worlds model and explaining why six degrees works. Warning: the video is no longer available, due to right owner’s decision to remove it from vimeo. EDIT: Video available here To go further : Found here. Related Posts: No related posts.
