After the Dot-Bomb: Getting Web Information Retrieval Right This Time
Marcia Bates, an academic expert on usable information retrieval. suggests that if web entrepreneurs and VCs had known about the history of IR and library experiences, they would not have wasted investments in problematic approaches such as "push" technology. She offers seven suggestions to improve web retrieval: use faceted rather than hierarchical classification; don't try for a single "true" classification (and avoid the term 'ontology'); use subject and domain information retrieval vocabulary; remember the Bradford distribution; plan for explosive growth; provide tools for "human content processing"; learn from the history of information retrieval.
The Robots.txt file is a cooperative way to request that crawlers and spiders avoid certain parts of web sites. This free server module watches for spiders which read pages disallowed in robots.txt, and blocks all further requests from that IP address. It is particularly useful for blocking email address harvesters, while still allowing legitimate search engine spiders. Be sure to double-check your robots.txt file (use one or more of the robots.txt checkers), before implementing it, and to watch your server logs carefully. The August 2002 version (0.6) works with Apache 1.3 on FreeBSD and Linux.
