Java Agent Development Framework

Journal of Emerging Technologies in Web Intelligence, 2013

This article describes JADE Agent Programming Language (JAPL) that allows fast and efficient implementation of intelligent behaviors into mobile agents, based on three logical, FIPA speech acts, and a part of complex procedural script for actions. It integrates the ontologies and defines communication services. Rather than rely on a library of plans, JAPL allows agents to plan from first principles. It also describes how to program the multiple JADE behaviors using JAPL instructions and how to compile JAPL to JAVA classes.

Agent oriented programming is often described as the next breakthrough in development and implementation of large-scale complex software system. At the same time it is rather difficult to find successful applications of agent technology, in particular precisely when large-scale systems are considered. The aim of this paper is to investigate if one of the possible limits may be the scalability of existing agent technology. We have picked JADE agent platform as technology of choice and investigated its efficiency in a number of test cases. Results of our experiments are presented and discussed.

Abstract: Agent technology is widely spread on the software domain and agents can be found in a variety of applications and solutions. Java agents are agents written in the Java™ programming language. Java is considered the perfect language for writing agent solutions.

The semantic gap is distinguished by the difference between two descriptions generated using different representations. This difference has a negative impact on the developer productivity and probably, the quality of the written code. In software development context, the coding phase aims at coding the system consistent with the detailed project developed with a group of designed models. This paper presents an endeavor to consolidate different agent type definitions and implementation concepts for Multi-Agent Systems (MAS) involving the adaptation of the JADE framework regarding the theoretical concepts in MAS. Additionally, it contains a standardization of code generation. The main benefit of the proposed extension is to include the agent internal architectures, entities and relationships in an implementation framework and increase the productivity by code generation, ensuring the consistency between design and code. The applicability of the extension is illustrated by developing a...

This paper describes a novel programming language called JADEL, a language designed to support the effective implementation of JADE multi-agent systems in the scope of model-driven development. First, the urge for a JADE-specific language is motivated and, then, the proposed language is described in detail. The four core abstractions that JADEL supports, namely agents, behaviours, communication ontologies, and interaction protocols, are presented by gradually introducing the specific syntactic rules that the language adopts for them. The sketch of a complete example of a multi-agent system written with JADEL is discussed in the last part of the paper, together with a preliminary quantitative assessment of the language.

Agent oriented programming is often claimed to become the next breakthrough in development and implementation of large-scale complex software systems. At the same time it is rather difficult to find successful applications of agent technology, in particular when large-scale systems are considered. The aim of this paper is to investigate if one of the possible limits could be the scalability of existing agent environments. For this purpose we have selected JADE agent platform and investigated its performance in a number of test-scenarios. Results of our experiments are presented and discussed.

Multi-agent systems have proven to be a powerful technology for building complex distributed applications. However, the process of designing, configuring and deploying agent-based applications is still primarily a manual one. There is a need for mechanisms and tools to help automate the many development steps required when building these applications. Using the Semantic Web ontology language OWL and the JADE platform we have developed a number of models and associated software tools that provide an end-to-end solution for designing and deploying agent-based systems. This solution supports the construction of detailed models of agent behavior and the automatic generation and deployment of agents from those models. We illustrate its use in the construction of a complex multi-agent system called BioSTORM that supports the configuration, deployment, and evaluation of analytic methods for detecting outbreaks of infectious diseases using public-health surveillance data.

Agent-Oriented Programming (AOP) provides an effective level of abstraction for tackling the programming of mainstream software applications, in particular those that involve complexities related to concurrency, asynchronous events management and context-sensitive behaviour. In this paper we support this claim in practice by discussing the application of AOP technologies -Jason and CArtAgO in particular -for the development of smart nomadic applications based on the Google Android platform.

ThePl ioce ne(5.3-2.6 Ma) of Tibet witnessed the drying of the northern Tibetan Plateau and the approach to the Pleistocene Ice Age within the background of intensifying Indian and East Asian monsoons. Yet little is known about Pliocene mammals living on the high Tibetan Plateau despite the fact that fossil mammals elsewhere constitute an important knowledge base for terrestrial environments. The late Miocene to Pleistocene Zanda Basin at the northern foothills of the Himalayas affords a welcome opportunity to evaluate the biological response to environmental change at high elevations. Abundant, well-preserved fossil mammals and fish from an 800-m continuous section of fine-to coarse-grained sediments thus open a rare window into a past biological world. For example, the discovery of an ancestral wooly rhino from Zanda Basin that was the precursor of its late Pleistocene megafaunal descendants leads to our "out-of Tibet" hypothesis, suggesting that the high Tibetan Plateau was a Pliocene cradle for Ice Age cold adaptations. In this paper, we document in detail the mammalian biostratigraphy, chronology, and paleozoogeography based on Zanda Basin fossil mammals. Our high-resolution biostratigraphy and biochronology offer for the first time independent constraints that both support and modify recent magnetostratigraphic correlations. Using characteristic Pliocene and Pleistocene mammals, particularly the small mammal assemblages in the lower part of the section and monodactylid Equus from the upper section, we propose a correlation to C1n to C3An.1r, with an age range of~400 Ka to 6.4 Ma. Within the 800-m Zanda section, the lower 0-150 m is of latest Miocene age, spanning 6.4-5.3 Ma. Sparsely fossiliferous, the lower section has produced five taxa so far: Ochotona, Panthera, Qurliqnoria, Palaeotragus,a n d Hipparion-all are consistent with a late Miocene age. The middle 150-620 m section spans the entire Pliocene. This section is by far the most fossiliferous, including such typical Pliocene small mammals as Prosiphneus, Mimomys, Apodemus,a n dTrischizolagus, as well as large mammals such as Coelodonta thibetana, Hipparion zandaense, Chasmaporthetes, Nyctereutes, Meles, Antilospira, and others. In the upper 620-800 m section the fossils are rare, but do include characteristic Pleistocene taxa such as Equus. Zoogeographically Zanda Basin mammals are a mixture from two major sources. Taxa such as Mimomys, Prosiphneus, Trischizolagus, Chasmaporthetes, Nyctereutes, Meles,andXenocyon are commonly found in north China or east Asia. In contrast, several forms, such as unique species of pikas (Ochotona), squirrels (Aepyosciurus), and ancestral Tibetan antelope (Qurliqnoria), seem to belong to an indigenous Tibetan fauna evolved within the plateau. A lack of shared taxa with the Oriental Realm suggests a formidable barrier by the Himalayas despite a short distance (~100 km) between Zanda Basin and the Indian subcontinent.
