What?
  • we want to know about strong or weak relationship intensity between two users

  • also the user can control evolution of his or her relationships to friends

Abstract

We present a method for analysis of the evolution of userís relationships and its evaluation by means of developed web-based application, which approximates the userís relationships with other users in time. This approximation is based on varied userís activities performed in social networks. Example of this activity is sending a message or uploading common photography. Such activity we denote as a rate factor.

We can use many sources of userís activities to evaluate proposed method. We chose for the experiment well known and popular social portal Facebook. We developed software tool named IRe to realize the proposed method. In the experiment we achieved many results, one of them is that the method calculated relationship intensity for first ten best friends with 88% precision.
