| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Most of the
directories are very general in scope and list websites across a wide
range of categories, regions and languages. But there are also some
niche directories which focus on restricted regions, single languages,
or specialist sectors. One type of niche directory with a large number
of sites in existence, is the shopping directory for example. Shopping
directories specialize in the listing of retail e-commerce sites.
Examples of well known, general, web directories are Yahoo! Directory
and the Open Directory Project is significant due to its extensive
categorization and large number of listings and its free availability
for use by other directories and search engines. However, a debate over
the quality of directories and databases still continues, as search
engines use ODP's content without real integration, and some experiment
using clustering. |
