Unformatted text preview: CS-103 Bruce Hoppe October 23, 2007 Homework 6 1) the 2) The rich-get-richer phenomenon appears in the rounded area between the vertical drop and the horizontal decrease to zero. The longer the curve, the greater effect. The birds of a feather effect appears in the length of the decreasing horizontal line in the Long Tail. The decrease seems to stretch out as more and more "friends" catch on to the trend and join the original consumer. John Cassidy seems to say that in this part of the Long Tail, the power distribution is at low point. "Six Degrees," however, claims that, during the Long Tail, the power distribution is at one of its highest points. 3) 4) There are a few differences between the roughly-stable end-state model, and the scale-free network. The scale-free network allows for node decay as time passes, which means that several edges would then be eliminated and replaced elsewhere. The scale-free network does not allow for this, meaning that the number of edges changes, but never the number of nodes. Towards the end of the scale-free network's life, the number of nodes would drop off sharply, and there would be a definite decrease in the number of edges overall. The roughly-stable end-state model continues to increase the number of edges up until the simulation is over. 5) As more and more users develop connections between their search query terms and the final websites they select from the Grokker results, Grokker will continue to develop the results for that specific term by including the chosen result in one of the initial result listings. This will increase efficiency and result in an increase in the number of edges between each search term. ...
