Web Noise
Recommendations and details concerning the critical evaluation of resources are important when the information is made available on a web site. When evaluating information on the web, it is important to ask: "Who created this web page?", "Who placed this information on the web?", "Is the information biased?" In other words, it is important to critically assess information found on the web.
A significant problem associated with "web noise" is the lack of controlled vocabulary. New methods are being developed to provide web pages with controlled indexing (such as XML -- Extensible Markup Language), but for all practical purposes, the vast majority of web pages do not feature controlled indexing; they are keyword-searchable only, as a result, web search engine searching is not generally precise and efficient for in-depth searching.
