支持交互的信息查询系统可用性原则的研究

Research on the Usability Principles of Information Search Systems for Supporting Interaction

信息查询系统可用性研究经过近半个世纪的发展,研制出数量庞大、种类多样的可用性原则,但存在着难于理解、难于查找使用的问题。文中提出先按可用性条目所适用的交互阶段划分,再按其所影响的可用性特性进一步细分,从而形成支持交互的信息查询系统可用性原则的组织结构。根据这一组织结构,选择与信息查询系统有关的六种有代表性的可用性原则,将可用性条目组织成一个支持交互的信息查询系统可用性原则,既可以从交互阶段的角度又可以从可用性特性的角度查找使用条目。利用支持交互的信息查询系统可用性原则的组织结构,为可用性条目管理提供了一个组织体系,为理解可用性条目提供了情境因素,不仅有利于查找使用可用性条目,还有利于深入地研究可用性原则及其条目。

After fifty years＇ development of research on the usablilty of information search systems,numerous and multitudinous types of usability principles have been raised.However,the problems of hard to understand and operate still remain.This paper first classifies the usability items according to the interaction stages of information search,and then,classifies the usability items according to the usability characteristics that it affects,which leads to the forming of the organizational structure of the usability principles of information search systems for supporting interaction.In accordance with the organizational structure,six typical usability principles relating to the information search systems build a usability principle of information search systems for supporting interaction.It enables the item-searching function to be operated by the requirements of interaction stages and usability characteristics.The utilization of the organizational structure devises an organizational system for managing usability items and provides a specific circumstance for further understanding towards them,which benefits not only the searching for usability items but also the deeper and further study on usability principles.
