Human powered directories
These directories compile listings of websites into specific industry and subject
categories and they usually carry a short description about the website. Inclusion in
directories is a human task and requires submission to the directory producers. Visitors
and researchers over the net quite often use these directories to locate relevant sites and
information sources. Thus directories assist in structured search. Another important
reason is that crawler engines quite often find websites to crawl through their listing and
links in directories. Yahoo and The Open Directory are amongst the largest and most well
known directories. LookSmart is a directory that provides results to partner sites such as
MSN Search, Excite and others. Lycos is an example of a site that pioneered the search
engine but shifted to the Directory model depending on AlltheWeb.com for its listings.
