The purpose of the invention described below is to make the information available via the Internet (broadly defined to include intranets and extranets) more useful for applications which need to distinguish not only the factual content, but also other dimensions of information content. One example of a type of information content which is not factual is emotional content Current search engines allow for keyword searches, but it is quite cumbersome to use these engines to pick out sites with specific emotional tones. For-instance, suppose one wanted to use a currently existing search engine to pick out all of the English language internet sites containing predominantly negative references to Microsoft corporation. The English language is complex enough that the task of forming the right keyword and phrase list is formidable. Simply looking for adjectives like "bad" or "disappointing" or "frustrating", etc combined with the keyword Microsoft will yield thousands of false matches. Such a search would also miss many overall negative sites because the methods of expressing negativity in the English language are so varied.
