Abstract

For many, the greatest benefit of the Web is to allow a growing number of services to be accessed from offices and homes. Today’s Web grants direct access to financial, travel, commercial, and trading information at the same time that it facilitates buying and selling books, electronic equipment, stocks, bonds, and airline tickets, just to mention a few among myriad other options. The possibilities seem infinite, but the underlying Web technology falls short at a crucial point: there is no information about information. Any ordinary search will typically bring, together with the desired results, a large amount of worthless information. This situation, known to database experts as the “low precision, high recall” scenario, is hindering the usability of search engines. To ameliorate this situation, it is paramount to properly index Web resources, in other words, to add annotation elements that explain what the Web resources are about.
