Associative vs. Analogous Reasoning

There are many different types of reasoning, but not too many have been successfully automated beyond deductive linear reasoning and various statistical methods. What alternative methods has the Web facilitated? One obvious candidate is associative reasoning, where reasoning on the basis of associations - which can be extremely unpredictable and personalized - takes one down a train of thought [202]. So, for example, the classic case of associative reasoning is given in Proust's novel Remembr...

 Page Rank Algorithm and the Kleinberg's HITS algorithm

The most famous quality measure is PageRank [221], discussed earlier, which builds on the intuition that a page which is cited by many other pages is likely to be of significant quality. The insight of PageRank is that the obvious way to subvert that model is to set up a load of dummy pages to cite the page which one wanted to boost. But if a page is cited by many other pages which themselves have a high PageRank, then it is likely to be of high quality. The PageRank method has another intuit...
