In centralised reputation models, a reputation system receives feedback about the interactions among the agents. Each agent evaluates the behaviour of the agents with whom it interacts and informs the reputation system. The system puts together all evaluations and stores such rep- utations. In contrast, in distributed reputation models, each agent evaluates and stores the reputations of the agents with whom it has interacted with and is able to provide such information to other agents. With the aim to cope with the problems of centralised and distributed rep- utation mechanisms3, we proposed the use of a hybrid mechanism [12]. In the distributed part of such a mechanism, agents evaluate the behaviour of other agents by exchanging opinions and storing such information. An opinion has to be justified by providing, for instance, the set of violated norms that contribute to that opinion. This work is framed in organisational environments that provide a minimum set of organisational mechanisms to regulate agents\u2019 interactions. Formally, an organisation is defined as a tuple g, , , \u03c6, x0, \u03d5, om, om where g represents the set of agents participating within the organisation; is the set of actions agents can perform; stands for the environmental states space; \u03c6 is a function describing how the system evolves as a result of agents actions; x0 represents the initial state of the system; \u03d5 is the agents\u2019 capability function describing the actions agents are able to perform in a given state of the environ- ment; om is an organisational mechanism based on organisational norms; and om is an organisational mechanism based on roles that defines the positions agents may enact in the organisation (see [5] for more details). Agents participating in the field of such organisations are involved in different situations. A situation is defined as a tuple g, , , T , that represents an agent g, playing the role , while performing the action , through a time period T . As detailed in [5], different types of situations can be defined following this definition. For instance, situations in which an agent performs an action, regardless of the role it is playing \u2013 g, , , \u2013, or situations in which an agent is playing a role along a time period, regardless the action it performs \u2013", "snippet_links": [{"key": "the-agents", "type": "definition", "offset": [285, 295]}, {"key": "the-system", "type": "definition", "offset": [404, 414]}, {"key": "to-provide", "type": "clause", "offset": [630, 640]}, {"key": "such-information", "type": "definition", "offset": [641, 657]}, {"key": "other-agents", "type": "definition", "offset": [661, 673]}, {"key": "an-opinion", "type": "clause", "offset": [963, 973]}, {"key": "provide-a", "type": "definition", "offset": [1137, 1146]}, {"key": "the-organisation", "type": "clause", "offset": [1352, 1368]}, {"key": "state-of", "type": "clause", "offset": [1562, 1570]}, {"key": "the-actions", "type": "clause", "offset": [1631, 1642]}, {"key": "able-to-perform", "type": "clause", "offset": [1654, 1669]}, {"key": "based-on", "type": "definition", "offset": [1743, 1751]}, {"key": "more-details", "type": "clause", "offset": [1904, 1916]}, {"key": "field-of", "type": "definition", "offset": [1947, 1955]}, {"key": "an-agent", "type": "clause", "offset": [2074, 2082]}, {"key": "time-period", "type": "clause", "offset": [2145, 2156]}, {"key": "types-of", "type": "clause", "offset": [2191, 2199]}], "samples": [{"hash": "4EABTzCi0FI", "uri": "/contracts/4EABTzCi0FI#previous-work", "label": "Reputation Based Agreement", "score": 19.725402832, "published": true}, {"hash": "7o1vnmMM6Ar", "uri": "/contracts/7o1vnmMM6Ar#previous-work", "label": "Reputation Based Agreement", "score": 19.0, "published": true}], "hash": "770908f40cd6dd8bdbd40d8d9db66d34", "id": 2}, {"size": 3, "snippet": "Broadcast: For the standard communication model with a complete synchro- nous network of pairwise authenticated channels, Pease, Shostak, and \u2587\u2587\u2587- port [PSL80] proved that perfectly secure broadcast is achievable if and only if less than a third of the players is corrupted: t < n/3. This tight bound more generally holds with respect to a network of secure channels and unconditional security, i.e., when even allowing a negligible error probability, as proven by \u2587\u2587\u2587\u2587\u2587\u2587 and \u2587\u2587\u2587 [KY].
