 Internet-Literate Student Skills

An understanding of what the Internet is. "I found it on the Internet" is not an accurate statement. You found it on a computer connected to the World Wide Web. Ways to formulate queries. Typing "childhood obesity" into a search engine is not the best way to discover what health problems are associated with being overweight. Students need to know about Boolean searches, adding prefixes such as SITE and FILETYPE, and more. For example, "site:.edu childhood obesity" will yield search results fr...

 The Problem of Machine-Aggregated Knowledge

he nuts and bolts of artificial-intelligence research can often be more usefully interpreted without the concept of AI at all. For example, in 2011, IBM scientists unveiled a “question answering” machine that is designed to play the TV quiz show Jeopardy. Suppose IBM had dispensed with the theatrics, and declared it had done Google one better and come up with a new phrase-based search engine. This framing of exactly the same technology would have gained IBM’s team as much (deserved) rec...

If an AI works by aggregating the works of the sum total of human knowledge, should the humans that discovered that knowledge be compensated? Science works the same way, but ideas remain free.

 Using Google is Like Watching Fox News or MSNBC

That's something I picked up in science, I suppose -- wanting to know the other side of the story, testing one's ideas against the alternative. Of course, one is naturally predisposed to what one already believes. Early nurturing and education is not to be discounted. One might even have a genetic nudge toward liberality or conservatism. Still, it behooves one to approach alternative views with an open mind, or at least as open as one can manage. [...] And now I read Sue Halpern reviewing ...

 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...

The page rank algorithm is very similar to an algorithm for ranking research papers by counting the number of other papers referencing them.
