Google Directory

A popular search engine with many features. It uses the ODP RDF dumps in the directory section.

Up until now, we've shown you how to choose search terms and craft your queries to locate the information you seek. 

 

This section describes how to browse by following links on Google's Directory.

Google Directory Information 

 

 Google's web-search index is built automatically by computers that crawl the web. On the other hand, Google's Directory is created by volunteer human-subject matter experts who contribute to the Open Directory Project (www.dmoz.org). The raw open-source directory is used not just by Google, but also by Netscape Search, AOL Search, Lycos, HotBot, and DirectHit. The volunteers evaluate, classify, and annotate each entry. The entries are then ranked by Google's PageRank algorithms.

 

Use Google's Directory when you want to explore by clicking on topics, i.e., browse. For example, learn about travel by clicking on the Travel category, which is included in the top-level category Recreation, which in the future we'll abbreviate as Recreation > Travel.

 

Directory drawbacks include size, timeliness, and coverage. Since computers can crawl the web and add index entries much faster than humans can travel the web and evaluate pages, most directories, including Google's, have significantly fewer entries than searchable indices. Since directory links are maintained by hand, upkeep and maintenance are time-consuming. It's difficult for editors to keep up with the dynamic nature of the web. Because different people edit, annotate, and add entries, some categories in a directory are well-populated and others are sparse.
