1. Method for automatic selection and presentation of digital messages for a user, CHARACTERISED BY the following steps:

  • an interest profile of the user is generated in the form of an interest vector in a K-dimensional space in which K is the number of characteristics that discriminate whether a document is or is not considered relevant for the user, wherein a weight is assigned to each word by the user in accordance with the importance assigned by the user to that word;

    for each message, on the basis of words occurring in the message, a content vector is generated in an N-dimensional space in which N is the total number of relevant words over all messages, with a weight being assigned to each word occurring in the message in proportion to the number of times that the word occurs in the message relative to the number of times that the word occurs in all messages;

    the content vector is compared with the interest vector and their distance is calculated;

    messages for which the distance between the content vector and the interest vector does not exceed a given threshold value are presented to the user.
