Web directories

Web directories are efforts to classify by subject matter all different types of Internet sites. Web directories are usually arranged as some sort of interconnected hierarchy consisting of several layers. Web directories enable users to search the web by subject matter. Some examples:

Search engines

Search engines (at least text-based ones) are vehicles that allow users to find Internet sites that contain particular text, words or phrases. The basic technology employed by just about every search engine involves, at its most simple level, a matching of query terms to terms in a document (with many, many complex variations on this single theme). Once the search engine has retrieved documents containing the text specified by the user, the search engine then ranks the pages or sites retrieved. The ranking mechanisms vary greatly among search engines, with sophisticated techniques being employed to rank retrieved sites along different parameters. Meta-search engines are retrieval mechanisms that gather the results of a particular query from several search engines. The trend in search engine technology is to personalize (or at least allow manipulation of) results based on the individual user (or what the search engine can glean about the individual).
