Reputation concerns may help to achieve efficiency in cases where imperfect information impedes it. In this paper I highlight the endogenous property of reputation and analyze how it undermines the effectiveness of reputation to achieve efficiency. More reputation implies the possibility of undertaking more activity. At the same time, more activity generates more signals under which reputation ...

In dynamic ubiquitous computing environments, system entities may be classified into two main categories that are, in principle, in conflict. These are the Service Resource Requestors (SRRs) wishing to use services and/or exploit resources offered by the other system entities and the Service Resource Providers (SRPs) that offer the services/resources requested. Seeking for the maximisation of t...

Developmental Biology's excellent reputation in Freiburg goes back to the days of the Hans Spemann who received the Nobel prize for his groundbreaking discovery of an "organizer center" in early amphibian embryos that controls the behavior and fate of surrounding cells. Today the University of Freiburg is one of the few universities in Germany that offers a full curriculum in Developmental Biol...

Gavagai used its commercially available system for the filtering and polarity tasks in the evaluation campaign for online reputation management systems at CLEF 2013. The system is built for large scale analysis of streaming text and as part of the services Gavagai provides, it measures the public attitude visavi targets of interest. This mechanism — with no adjustment for this specific task — w...

This paper introduces a set of principles for governing the design and operation of online reputation systems. We also introduce the design, architecture, and implementation of a flexible, general-purpose framework, called Pythia, for building reputation systems. We give a sample application of our framework to illustrate its use.

Reputation-management, as proposed for dynamic and open systems aims to provide mechanism for analysing the behaviour of agents, and to distribute this information so that the impact of the actions of those acting against the interests of a community can be limited. We study the assumptions that underpin this decisionmaking role for reputation-management and highlight its limitations with regar...

The objective assessment of the prestige of an academic institution is a difficult and hotly debated task. In the last few years, different types of University Rankings have been proposed to quantify the excellence of different research institutions in the world. Albeit met with criticism in some cases, the relevance of university rankings is being increasingly acknowledged: indeed, rankings ar...
