                            CALL FOR PAPERS
----------------------------------------------------------------------

The workshop  on Declarative Agent Languages  and Technologies (DALT), in  its tenth  edition this
year,  is a  well-established forum  for researchers  interested  in  sharing  their experiences  
in  combining declarative  and  formal approaches  with  engineering and  technology aspects  of 
agents  and  multiagent systems.   Building complex  agent systems calls for models  and 
technologies that ensure predictability, allow for  the verification of properties,  and guarantee 
flexibility. Developing  technologies  that can  satisfy  these requirements  still poses  an  
important   and  difficult  challenge.   Here,  declarative approaches  have the  potential of  
offering solutions  satisfying the needs   for  both  specifying   and  developing   multiagent  
systems. Moreover,  they  are gaining  more  and  more  attention in  important application   areas
such  as   the  semantic   web,  service-oriented computing, security,  and electronic contracting.

DALT 2012 will be held as a satellite workshop of AAMAS 2012, the 11th International  Joint 
Conference  on Autonomous  Agents  and Multiagent Systems,  in June  2011 in Valencia, Spain.   
Following the  success of nine previous editions, DALT will again aim at providing a discussion 
forum to  both (i) support  the transfer of declarative  paradigms and techniques  to   the  
broader  community  of   agent  researchers  and practitioners, and (ii) to bring  the issue of 
designing complex agent systems  to  the  attention  of  researchers  working  on  declarative 
languages and technologies.

DALT 2012 will have as a special interest topics those future trends of the web, where declarative 
languages and technologies for multiagents systems will play an effective role: in particular, 
social computing (models of social interactions, trust, commitments, and contracts; social  
environments based on declarative technologies) and its related semantic issues (explicit 
representation of knowledge and mechanisms for allowing societies of agents to reason on that).

----------------------------------------------------------------------
                           TOPICS OF INTEREST
----------------------------------------------------------------------

DALT topics of interest include, but are not limited to:


DALT 2012 special topic: declarative approaches for agent-based social computing
* models of social interactions among agents
* models of buiness interactions among agents
* models of trust, commitments, and reputation for agents
* declarative description of contracts and negotiation policies
* social environments based on declarative technologies
* Semantic Web-aware declarative agents

General themes:
* specification of agents and multi-agent systems
* declarative approaches to engineering agent-based systems

Formal techniques:
* (constraint) logic programming approaches to agent systems
* distributed constraint satisfaction
* modal and epistemic logics for agent modeling
* game theory and mechanism design for multi-agent systems
* semantics of agent communication
* model checking agents and multi-agent systems
* agent communication and coordination languages
* protocol specification, verification, and reasoning

Declarative models:
* declarative models of agent beliefs, goals and capabilities
* declarative models of bounded rationality
* declarative approaches for agent-based grid computing
* declarative paradigms for the combination of heterogeneous agents
* declarative approaches to organizations and electronic institutions
* agent-inspired declarative approaches to Web services and service-oriented computing

Applications of declarative techniques to:
* multi-agent systems for service-oriented computing
* agent-based grid computing
* security and trust in multi-agent systems
* e-health, e-commerce, e-learning, sociotechnical systems, social networks, virtual organizations.

Evaluation of declarative approaches:
* experimental analysis of declarative agent technologies
* industrial experiences with declarative agent technologies

                        SUBMISSION INSTRUCTIONS
----------------------------------------------------------------------

We  welcome and  encourage  the submission  of high-quality,  original papers, which  are not being
submitted  simultaneously for publication elsewhere.  Papers  should be written in  English, 
formatted according to the Springer LNCS style,  and not exceed 16 pages. Paper submission is 
electronic via the conference website.

----------------------------------------------------------------------
                          WORKSHOP PROCEEDINGS
----------------------------------------------------------------------

Printed copies of  the proceedings will be available  at the workshop.
Assuming a sufficient number of high-quality submissions, we are again going to  consider the 
publication of formal  post-proceedings with an international  publisher.   The post-proceedings  
of  DALT 2003  (LNAI 2990), DALT 2004  (LNAI 3476), DALT 2005 (LNAI  3904), DALT 2006 (LNAI 4327),
DALT 2007 (LNAI  4897), DALT  2008 (LNAI  5397),  DALT 2009 (LNAI  5948), and DALT 2010 (LNAI 6619)
have  been published  by Springer-Verlag  in the Lecture Notes in Artificial Intelligence series.
