When searching for information on the web, unless you know the address of the
web site you are seeking, most use a search engine. There are many search
engines on the internet, some that specialise in newsgroups or databases. Many
search engines are programmed to mine for data using algorithms for sorting and
categorising the data, whilst ‘web directories’ are maintained by human editors,
although some search engines may use a mixture of algorithmic and human
interaction. |
