The Cost of Trust in the Dynamics of Best Attachment
Vincenza Carchiolo, Alessandro Longheu, Michele Malgeri, Giuseppe Mangioni · 2015
The need of trust is growing in several contexts as e-commerce, virtual communities, distributed on-line services and many others as an essential precautionary component for users during interactions with strangers, either other people or virtual agents. Generally trust metrics endorse principle the higher trust, more legitimate that user will be''; a consequence is that getting trusted must require some effort, otherwise all participants would easily achieve high trustworthiness. In this work we study how a user can achieve and preserve a good trust and what costs it requires over time; we also investigate some heuristics that allow reducing complexity in exploring rank-effort space especially for large networks.
