摘要
The invention relates to a method and system for representing the relevance of electronic documents in relation to user-specific search and interest profiles. The relevance of each respective document in relation to specific search profiles is essentially determined by counting words. Documents and search profiles are interpreted as vectors, individual words are considered as vector components and the frequency of words is seen as values of vector components. The document vectors and search profile vectors are projected on a common plane and the angle formed by the vectors is used to measure the conformity of said document in relation to the respective search profile. The results of analysis are represented in three dimensions enabling the documents to be arranged in such a way that similar documents are located next to each other or documents which are relevant to a search profile are arranged close to said search profile. The system can be especially used in searches in computer networks such as Internet or for databank searches and visualization of library contents, archives or complex data stock of all varieties.
