Theoretical model

Serendipity is making a pleasant and relevant discovery that was unexpected. In SIRUP we argue that a serendipitous recommendation primarily induces interest in a user. Hence, serendipitous recommendations are those that trigger interest in users.

Building on the classic theory of interest by Daniel E. Berlyne and the follow-up work by Paul Silvia, we argue that user interest, and thus serendipity, is determined by two things: novelty (inherent to the recommendation) and coping potential (inherent to the user). Novelty, in turn, is determined by the complexity, familiarity and conflict characteristics of the recommended item.

Based on this logic, we present SIRUP’s theoretical model:
