1 Workpackage 2: Norms

2 WP2 (Norms): The Problem How to specify normative systems to regulate MAS, so that they may be properly implemented and one may reason about them

3 WP2: The problem Regulated MAS Declarative vs. procedural specification of conventions Higher level abstraction Richer governance models Dynamic conventions Reason about the norms Designer of the MAS / individual participant Offline / Online Language: Expressiveness Computational model (proof thy.) Implementation

4 WP 2 Norms: Tasks T2.1Computable Language for Normative Systems (Carles Sierra) Dedication T2.2 Individual Reasoning about a Normative System (Pablo Noriega) Dedication T2.3 Declarative specification of Electronic Institutions (Marc Esteva) Dedication

5 T2.1: Objective Design and implement a practical machine executable language for specifying norm regulated MAS that may be used by MAS designers as well as participating agents to reason about the normative system itself.

6 Task 2.1: Content A Computable Language for Normative Systems Expressiveness –Typical norms: facts, deontic modalities, conditions, associated actions, temporal features,... –Other normative features: authority, jurisdiction, hierarchy, conflict resolution policies,... Practical to implement and use Reason about norms –Convenient semantics & proof theory

7 Task 2.1 Activities A study of normative temporal logics –Formal properties –Operational semantics NTL-based language for normative systems Model checking and other proof theoretic tools for NTL- languages Reasoning about norms Examples of normative systems

8 T2.1 Workplan Phase 1: Identify needs and available technologies. Choose best features for a computable NTL-based language –Study of NTLs and relevant proof-theoretic mechanisms –Expressiveness requirements for normative systems –Desiderata for a system that supports reasoning about norms D2.1.1 A NTL primer (18 R) Phase 2: Design and implementation of a normative language D2.1.2 A machine readable language for norms (24 R) Phase 3: Construction and use of actual normative systems D2.1.3 Implementation of actual normative systems (40; 54 R&S)

9 T2.2: Objective Propose an agent architecture for agents that deliberate about their norm aware behaviour within a norm regulated social system

10 T2.2 Content Individual Reasoning About a Normative System Individual reasoning perspectives Introspective outlook (adopting, breaking a norm) vs pro-social outlook (social conformance, negotiation, group deliberation) Agent architectures to deliberate about norms Individuals reasoning off-line How to know what one is supposed to do and not to do. Criteria for norm compliance. Adapting behaviour to comply with rules. Individuals reasoning on-line Deciding when to infringe or comply with a norm. Adapting to the social environment Adopting evolving normative requirements

11 T2.2: Activities An agent architecture to reason about norms and actions. –BDI+Commit (context logics)+T2.1 language Evaluating norm adoption and compliance from an individual agent’s perspective: –Graded commitments. –Values, preferences and motivation –Coherence, cognitive dissonance. Reasoning about norms within society (adapting, conforming, defaulting and transgressing) –Peer-pressure and individual profiling –Argumentation, persuasive actions, sanctions –Collective decision-making (Game-theoretic models-judgement aggregation) Prototyping and deployment of agent populations in EIs

12 T2.2 Workplan Phase 1: An architecture for morally enabled agents. –Study and choice of relevant modalities, inference and coherence- maintenance mechanisms –Public and private moral-reasoning features (values, preferences, moral awareness,...) –Normative state D2.2.1 A BDI+C agent architecture (18 R) Phase 2: Introspective reasoning about norms (adoption, compliance and infringement) D2.2.2 Norm adoption models from a subjective perspective (24 R) Phase 3: Morally enabled agents in a norm-regulated EI. D2.2.3 An implementation of BDI+C agent societies in EIs (40; 54 R&SW)

13 T2.3 Objective Executable Norm-regulated Electronic Institutions

14 T2.3 Content (1) Commitment Management Commitment consistency. Can commitments be fulfilled? Reasoning at design and at run-time. Dynamic and concurrent commitment acquisition and fulfilment. Centralised versus distributed commitment management Global (institution) and local (agent) fulfilment.

15 T2.3 Content (2) Declarative language Expressiveness requirements for interaction conventions specification Mapping of the current EI procedural specification into the declarative language. More flexible specification, control and enforcement of the institutional rules.

16 T2.3 Content (3) Declarative language Integration Consistency between the declarative and procedural specifications. Realisability of a declarative specification. Updating of conventions at run-time. (Related to Autonomic Electronic Institutions) Reasoning about conventions at design and run-time.

17 T2.3 Activities Dynamic commitment management model Integration of the declarative language with the current procedural specification of institutions. Extension of EIDE platform.

18 T2.3 Workplan Phase 1: A dynamic commitment management model –Analysis of how commitments propagate –Commitment conflict management D2.1A dynamic commitment management model (12 R) Phase 2: Integration between procedural and declarative specifications D2.3.2 A norm-based extended EI model. Month (24 R) Phase 3: Extension of EIDE to support the commitment models and declarative-procedural specifications. D2.3.3 Declarative-procedural specification of EIs. (40 R&S)
