摘　　要：本文详细介绍了基于二叉式分类推理的昆虫分类辅助鉴定多媒体专家系统通用平台TaxoKeys的设计与开发 ,及其所具备的主要特点。该研究根据昆虫分类学的特点 ,将昆虫分类的两项式检索表用数据库表示成系统知识库 ,利用计算机数据结构中二叉树结构的分枝结点搜索技术来实现其推理过程 ,进行昆虫分类的辅助鉴定 ,为昆虫分类专家提供一个通用专家系统平台。该系统具有可扩充性好、设计简单、操作方便等特点 ,同时也适用于一般性生物分类鉴定。另外 。This paper describes the design and development of the platform of a multimedia expert system to assist taxonomic identification, as well as the characteristics of the system. This system, named Taxokeys, is based on the dichotomous reasoning method. From expertise of insect taxonomy, dichotomous taxonomic keys for the Insecta can be revised into a knowledge database in terms of data structure using computer technology. This database can then be used as the basis for insect identification by searching for nodes within dichotomous trees of the data-structure until the final node is reached. In fact, the system is a generalized platform for insect taxonomists to develop their own multimedia expert systems. Taxokeys has such features as ease of adding new data, simplicity in design, and simplicity of operation, and may be useful for biological identification and taxonomic study in general. The possibility of increasing additional functions and potential applications for this system are discussed.
