Abstract
A method of locating relevant documents wherein documents are given a fingerprint comprising weights associated with particular topic categories of a classification system, each weight representing a degree to which the document relates to the particular topic category. Documents whose fingerprints have a predetermined degree of mathematical overlap with the fingerprint may be considered relevant. A user is alerted to new relevant documents. Advertisers can offer advertisements near search results that achieve a predefined amount of relevance to text submitted by the advertiser rather than bidding on keywords. Unwanted content may be blocked from the search and filters to further refine the search may be used. E-mail spam may be blocked using textual relevance rather than keywords. Visual cues linked to a hierarchy of relevance help display the relevant documents. The methods may be used in combination with keyword searching.
