The CLEVER search engine incorporates several algorithms that make use of the Web's hyperlink structure for discovering high-quality information. It can be exceedingly difficult to locate resources on the World Wide Web that are both high-quality and relevant to a user's informational needs. Traditional automated search methods for locating information on the Web are easily overwhelmed by low-quality and unrelated content. Second generation search engines have to have effective methods for focusing on the most authoritative documents. The rich structure implicit in hyperlinks among Web documents offers a simple, and effective, means to deal with many of these problems. Additional Information: Publications:
Here’s a visualization concept I came up with a while back to look at the way search engines and word-of-mouth affects hit frequency on the iBiblio web-traffic log. iBiblio consists of around 420 sites. Each one of the circles you see represents one of the websites. The size of each pie slice inside grows with respect to the number of hits by individual search engines (see the legend for which ones). The size of the circle grows with respect to the overall number of hits by people other than search engines. Hits are counted by number of unique incoming IP addresses per day. Links get drawn between cliques of websites where more than 1/4th of the unique IP addresses are the same on that day, meaning, more or less, that those sites often share traffic. The total amount of data was around 10TB and the visualization took about a day to process into a static animation. The original is meant to run on a wall-sized (16′x9′) or on our specialized visualization dome.
