Boris Galitsky and Mark Levene: On the economy of Web links: Simulating the exchange process
In the modern Web economy, hyperlinks have already attained monetary value as incoming links to a Web site can increase its visibility on major search engines. Thus links can be viewed as investment instruments that can be the subject of an exchange process. In this study we build a simple model performed by rational agents, whereby links can be bought and sold. Through simulation we achieve consistent economic behaviour of the artificial Web community and provide analysis of its micro– and macro–level parameters. In our simulations we take the link economy to its extreme, where a significant number of links are exchanged, concluding that it will lead to a winner take all situation.
Susan L. Gerhart: Do Web search engines suppress controversy?
Web behavior depends upon three interlocking communities: (1) authors whose Web pages link to other pages; (2) search engines indexing and ranking those pages; and (3) information seekers whose queries and surfing reward authors and support search engines. Systematic suppression of controversial topics would indicate a flaw in the Web’s ideology of openness and informativeness. This paper explores search engines’ bias by asking: Is a specific well–known controversy revealed in a simple search? Experimental topics include: distance learning, Albert Einstein, St. John’s Wort, female astronauts, and Belize. The experiments suggest simple queries tend to overly present the "sunny side" of these topics, with minimal controversy. A more "Objective Web" is analyzed where: (a) Web page authors adopt research citation practices; (b) search engines balance organizational and analytic content; and, (c) searchers practice more wary multi–searching.
