The BDI Agent-Based Programming Language: BDI - APL
(Students: Wei Zhao 2002, Allen J. Arnold 2002, Dong Shi Zhang 2003)(Advisor: Dr. C.-H. Jo):

ABSTRACT Agent-based programming is emerging as a new programming paradigm for the next decades. The most popular concept, which is used in the agent-based programming, is the BDI concept. "B" stands for Believe (Data), "D" represents Desire (Goal) and "I" stands for Intention (Plan). Agent-base programming is composed with one or more Agents. Each agent has it's own B, D and I. In order to achieve some goal (Desire), the agent can analyze the related data (Belief) and choose an appropriate plan (Intention). Some kind of intelligence has to be added into the agent-based programming, so that the agent can dynamically choose certain plans to achieve it's goals. Unfortunately, there have been no proper programming languages, which can support agent programming naturally. Even though there are some agent-based languages, which are mostly based on the Java programming language, can support the BDI concept, some of them are hard to use and they cannot really and dynamically manipulate the BDI property. Therefore, we have developed our own language called APL (Agent-based Programming Language). It works on Java Virtual Machine (JVM). With the help of JDBC technique, we can dynamically manipulate the knowledge base which contains B, D and I. This project is to build a compiler for the APL. The APL compiler will take the APL program as input, compile it and generate Java bytecodes, which can run on the Java Virtual Machine (JVM). In this project, the Java programming language, the Java Virtual Machine, and some compiler tools such as Lex and Yacc will be used.

The Agent-Based Modeling Technique: AMT
(Students: Jeffrey M. Einhorn 2002, Guobin Chen 2003)(Advisor: Dr. C.-H. Jo):

ABSTRACT A success in agent programming is based on providing a good development of a feasible modeling methodology and its successful application in the real world. There are a few frontier research works in this area so far, but none of them suggests a seamless development methodology from modeling to implementation via agent concepts. The aim of this work is to produce an agent modeling technique that provides a consistent guide to develop software based on the BDI-agents.

Agent-Based Stock Trading
(Student: Xin Feng)(Advisor: Dr. C.-H. Jo):

ABSTRACT In this work, we develop a unique implementation scheme of the Belief-Desire-Intention (BDI) model to be used in an agent-based application using Java. The example prototype system we develop is the Agent-based Stock Trader (AST) that is a stock-trading expert based on intelligent agents. Agents in AST are based on the Belief-Desire-Intention (BDI) model in artificial intelligence. This work proposes a new idea to show how to program the BDI-based agents using the Java programming language, and how to make an agent-based application more intelligent and flexible. This work contributes new implementation scheme of the BDI agents in the Java programming language useful on many applications. This work can also show how nicely implement the BDI agents with Java while manipulating BDIs intelligently and dynamically at runtime. Using our concepts and implementation scheme, the internet-based application like stock trading can be more intelligent and flexible.

A Restaurant Finder using Belief-Desire-Intention Agent Model and Java Technology
(Student: Dr. Dongqing Lin, UM-Dulluth)(Advisor: Dr. C.-H. Jo):

ABSTRACT It has been becoming more and more important to design systems capable of performing high-level management and control tasks in interactive dynamic environments. At the same time, it is difficult to develop and maintain such complex systems with our traditional software techniques. The agent-oriented/based systems, rooted in a different view of computational entities, offer prospects for a qualitative change in this aspect. In this work, we adopt the basic architecture of a Belief-Desire-Intention (BDI) agent model and develop a more intelligent and dynamic searching model for agent programming. In the BDI model, the Desire is the goal to achieve or event to handle, the Intention is a set of plans to realize the predefined goal or react to a specific situation, and the Belief is the knowledge about the agent itself and the varying environment. Applying BDI concepts, we will build an experimental framework in our Restaurant Finder system. The belief, desire and intention are initially established as separate classes as in the object-oriented analysis and design, then these classes will be integrated as basic units for a BDI agent. The agent will possess learning behavior based on the user's feedback and the principle of inferring preferences. In addition, the agent will also update its knowledge dynamically based on analysis of user's interaction with the system. The dramatic increase in the use and availability of mobile devices has resulted in the ability to access information anytime and anywhere. Our Restaurant Finder system is designed for use on mobile phones. This system has architecture. The client tier is a J2ME (JavaTM 2 Micro Edition) emulator for the primary interface. In the middle tier, the Apache Tomcat Server will be installed to process the client's request, update the system database, and send back the recommendation. The information tier is a database system using the IBM Cloudscape database. The Restaurant Finder system will Cloudscape database. The Restaurant Finder system will J2ME Mobile Information Device Profile (MIDP) client application design.

(Student: A. S. M. Rokanuzzaman)(Advisor: Dr. C.-H. Jo):

The UND Atmospheric Science Department pursues research project related to weather related data acquisition, data processing, and data storage. The processed data is intended to make available to end users who may be a novice user in Atmospheric Science or may be a scientist in this field. The end users are considered to be unfamiliart with the data processing complexities. Hence, the end users will be given maximum flexibility in retrieving data from UND Atmospheric Sciences Department. UND Atmospheric Sciences Department maintains a website, which mainly focuses on weather related research works. From this work, the website can be updated so that the user may use nice user interface to use the system easily, and the new system provides the result as a function of several parameters in graphical forms. The data acquisition, data processisng performed by Atmospheric Sciences Department will be stored for retrieval by the Atmospheric Radiation Measurement (ARM) investigators or any interested party or individual. Through the new system, any individual can determine which citation flight data and variables to request from the archive. The end users can view the data in graphical form with no knowledge of data aquisition, data processing complexities. The user can view the data as finished product in graphical forms. The data represented in graphical forms will help researchers, faculty members, and students around the world to enhance their horizon of knowledge in Atmospheric Science. The participant in this research have worked as a research assist in the UND Atmospheric Sciences. The basic knowledge on Java internet programming, Java Server Programming, and distributed computing are expected, but not required to accomplish this project.

Design and Implementation of a Concurrent Object-Oriented Language

We have developed and implemented the Parallel-C++ language on various machines. This research work is to re-design the language concepts to support mobile agent computing, and implement it on a concurrent machine. Any experimental programming using the language adaptable for the real world applications such as aerospace simulation or mobile computing is also possible. The technique used here can be applied to develop any compiler or interpreter for both general purpose programming languages and special purpose languages (such as command languages for database, robot or aerospace manipulation). It also can be applied to extract any pattern in scientific/engineering data (such as sensing, GIS information, or satellite information) and trasform into other format/patterns.
