Talk:Content filtering
From Wikipedia, the free encyclopedia
Content_filtering#Filtering_methods basically speaks more about email content filtering. Can it further be improved by adding methods used by content filtering proxies and application layer firewalls, for web content filtering?

[edit] A rather narrow definition.
"Content filtering is the technique whereby content is blocked or allowed based on analysis of its content, rather than its source or other criteria."
The term "content filtering" IS often used to refer to filtering of content based not only on its nature, but its source as well, as part of the context. For instance, a filter might block a web page mentioning bomb-building techniques if the source is a terrorist website, but not if it is a news site. Perhaps the article should clarify that the term is often used this way to refer to filtering of content, regardless of basis, as opposed to filtering of content based only on the content itself. The narrower definition is more rarely used.
On what is the exclusionary definition based? Should it perhaps read "...based on analysis of its content and/or context, although some would not include context in a narrower definition."?
