"基于多主体和本体的贸易技术壁垒预警系统的实现" 贸易技术壁垒(Technical Barriers to Trade, TBT)是国际商务中的一大挑战，尤其对于出口导向的企业而言，及时预见并应对这些壁垒至关重要。为了满足这一需求，本文提出了一种结合多主体系统和本体论的预警系统，旨在提升对贸易技术壁垒的预测和预警能力。多主体系统（Multi-Agent System, MAS）是一种分布式计算模型，其中各个智能体代表不同的实体，如企业、政府机构或市场参与者，它们相互协作并独立决策。在本文中，MAS用于模拟复杂的国际贸易环境，每个智能体根据其特定的目标和策略与环境和其他智能体交互。关键的技术涉及选择合适的开发环境，如Java Agent Development Framework (JADE)等，以及采用适当的开发方法，如Agent-Oriented Software Engineering (AOSE)。此外，系统设计考虑了多进程和多线程模式，以实现并行处理和高效的信息交换。为了确保通信的可靠性，研究中可能探讨了消息传递协议（如FIPA-ACL）和一致性维护机制。本体论（Ontology）是知识表示和共享的重要工具，特别是在知识工程和知识管理领域。本体提供了一种形式化的方式来描述和组织领域的概念、属性和关系，使得计算机可以理解和处理领域知识。文章深入探讨了本体的背景，包括其哲学基础和在信息检索、数据集成等方面的应用。它还介绍了本体建模语言，如OWL（Web Ontology Language），以及本体推理和匹配算法。当前的研究状况表明，本体已被广泛应用于知识表示、语义网、智能决策支持系统等领域。文章对未来的发展进行了展望，可能包括更高级的本体学习方法、自动化的本体维护和更新，以及在国际贸易预警中的深入应用。关键词：多主体，本体，技术，贸易壁垒通过这个系统，企业能够及时获取到潜在的贸易壁垒信息，提前进行应对策略的规划，从而降低贸易风险，提高出口的成功率。同时，本体的使用使得知识的共享和理解更加精确，提高了预警系统的智能化水平。这一创新的预警系统为国际贸易提供了一个强大的工具，有助于企业在全球市场中保持竞争力。

Implementation of Early Warning System for Technical Barriers to

Trade based on Multi-Agent and Ontology

Abstract

According to the urgent demand for exports of technical barriers to trade early warning and prediction in the

presence of technical difficulties, we propose TBT early warning technology of multi agent and Ontology

prediction system based on the design scheme, and gives the key technology to realize the. In this paper, the key

technologies of the implementation of multi-agent system are studied deeply, from the developer's perspective,

discusses the development environment, development method selection, multi process and multi thread mode,

realize the reliability of communication and layered structure etc.. The concepts and methods of ontology have

received great attention in the fields of knowledge engineering and knowledge management, and have been

widely used. We introduce its background and related concepts, methods, and the current research situation, and

make a prospect for its future development.

Keywords: Multi-agent, Ontology, technology, trade barrier, early warning and prediction, system design

1. Introduction

According to the WTO's "technical barriers to trade agreement", technical barriers to trade to national

security or the protection of human health and safety, animal or plant life or health, protect the environment and

prevent fraud as a reason to trade protectionism for the purpose of the provisions of technical regulations,

standards, packaging, labeling, certification, inspection and quarantine procedures. Some special technical

conditions are set up to set barriers for other countries to enter their own markets freely. TBT types, including

technical regulations, technical standards barriers, quality certification barriers, packaging and labeling and

green barriers, inspection procedures and inspection procedures, barrier system of units of measurement barriers,

barriers such as bar code.

With China's accession to the WTO and the acceleration of economic globalization and trade liberalization,

TBT has become the main factor to stop China's exports, and it is also increasing year by year. According to

statistics, in 2006, 60% of China's export enterprises were subject to foreign TBT restrictions to varying degrees,

about 45 billion U.S. dollars of exports were affected.

Under the influence of foreign TBT, one of the main reasons that our products are blocked, the enterprises

are limited and the economy is damaged is that our country's information is not sound. Therefore, the

establishment of early warning mechanism of foreign TBT, timely collection and tracking of foreign technical

barriers and green barriers measures related information. As is known to all, there are many kinds of export

products in china. Due to the different technical level and different ideas, different countries generally have

great differences, and these differences are in constant change. At the same time, TBT also has dual nature,

complexity, concealment, flexibility and universality. Because of these reasons, it is difficult to realize the

prediction work of TBT. Because of this, the domestic practical, efficient, timely and accurate TBT early

warning and forecasting system has not yet produced.

Aiming at the problem of the urgent needs of our export products TBT prediction and its implementation

on the proposed early warning forecasting system and multi-agent based on Ontology technology, and gives the

key technology to realize the. The system has the functions of automatic collection and classification of TBT
