Human powered directories

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 for its listings.
