A discussion on trust requirements for a social network of eahoukers Manuel Graña J. David Nuñez-Gonzalez Bruno Apolloni 1HAIS 2013, Salamanca, 11 sept.

Index 1.- Introduction 2.- Trust related definitions 3.- A conceptual map description of a SandS session 4.- Discussion 2HAIS 2013, Salamanca, 11 sept.

1.- Introduction MAKE A DECISION RISK uncertainy about results we expect unknown consecuences Based on INFORMATION SOURCES TRUST that we built in FEEDBACK PROCESS bad results TRUST + + TRUST - - good results 3HAIS 2013, Salamanca, 11 sept.

1.- Introduction TRUST APPLICATION CONTEXTS Networking, semantic web, computational models, game theory and agents, software engineering, education, medical sensor networks, industrial digital ecosystems, e-commerce. Home appliance management and interaction in the domestic environment. SandS project eahoukers Home appliances deal with benefits from generated knowledge Intelligent layer that produces NEW SOLUTIONS 4HAIS 2013, Salamanca, 11 sept.

2.- Trust related definitions Trust Properties TRUST PROPERTIES Distance- based aging Reflexivity Asymmetry Dynamicity Time-based aging Non Transitivity Personalization/ Subjetivity Context- dependency Non antisymmetry 5HAIS 2013, Salamanca, 11 sept.

2.- Trust related definitions Trust Models Models – Cognitive – game theoretical – Hybrid Modes of trust – Establishment – Reasoning – Action Types of trust – Basic – General – Situational Representations – fuzzy terms, logic values, real numbers, Integers and arrays 6HAIS 2013, Salamanca, 11 sept.

2.- Trust related definitions Trust Metrics Zhang’s Metrics – Binary State Metric – Discrete Scale Metric – Propabilistic Metric – Hybrid or multi-metric trust – Negative values 7HAIS 2013, Salamanca, 11 sept.

3.- A conceptual map description of a SandS session SandS project eahoukers Home appliances deal with benefits from generated knowledge Intelligent layer that produces NEW SOLUTIONS 8HAIS 2013, Salamanca, 11 sept.

4.- Discussion Conflicts In Sands project, trust computing can be involved in: – Identification of rogue users that may try to sabotage competitors’ appliances. – Quality of the recommendations coming from an specific user. – Consensus between users, meaning that they agree on the quality evaluation of the results. 9HAIS 2013, Salamanca, 11 sept.

4.- Discussion Mechanism HAIS 2013, Salamanca, 11 sept.10 USER RECIPE EVALUATION TRUST proposes Consulte & evaluate attribute Implicit attribute
