The main theme of ESAS 2014 is Applying Semantic Web technologies in developing software agents, mobile agents and multi-agent systems towards the integration of heterogeneous and mobile services in smart environments especially through big data, social networks, crowd sourcing, e-health, public web well-being, on-line education, and intelligent learning environments.  ESAS workshop series aims at garnering the synergy of both semantic and multiagent technologies by taking up both the Semantic Web and the web services or agent based systems aspects of the common research issue. Topics of interest span a wide spectrum in both theory and practice of autonomous semantic agents, context-aware intelligent agents, semantic web services, software agents, mobile agents, intelligent systems, agent architectures, multi-agent systems, agent communities, develop and inference ontology, cooperation and goal seeking through ontology, safety & security in systems, other QoS issues, and so on.     We envisage a strong undercurrent of intelligent software agents, mobile agents, and MAS running through this workshop; side by side with the use of semantic technologies, there are several foci of interest:Software Agents, Mobile Agents, and MAS: issues relating to architecture, implementation, coordination, service levels, security of pervasive semantic or otherwise agents.Agent, MAS and Semantic Web Technologies: concomitant utilization of specific technologies in agent, MAS, and semantic Web implementations; semantic agent communities & applications; case studies of best-practice MAS applications; projects in the making;Ontologies for Agents and MAS: agent cooperation and coordination ontology; ontology of workflow in MAS; ontologies for distributed applications and integration; sharing and semantic interoperability; discovery and operations on ontologies; trust & security issues;Platforms for semantic agent and MAS implementation: languages, frameworks, tools, integrated development environments and software engineering practices supporting semantic or otherwise software agent & MAS architectures, coordination, trust & security mechanisms, description, discovery and composition of agent-based services.Semantic Intelligence and Applications:  Big data, social network and crowd sourcing, e-health and web well-being, on-line education and intelligent learning environments applications based on ontology and semantic intelligence.Other subjects of relevance in semantic technologies, semantic software agents, mobile agents, agent-based and multi-agent systems.
