【摘要】： 法律案件讨论对法律学生专业知识学习具有重要的辅助作用,目前他们主要应用论坛作为常用的讨论工具,作为法律案件讨论工具论坛存在发言观点重复度高,发言组织混乱,互动性不强等缺点,影响了讨论的效率。法律讨论信息可视化有助于提高群体沟通的有效性,增强用户掌握处理信息的能力。目前虽然已经有多种法律讨论可视化系统,它们一般以某个法律推理方式为基础,而这种法律推理方式并不符合法律专业学生分析问题的思维方式,因此这些研讨可视化系统很难被法律学生广泛采用。本论文作者尝试设计一个符合法律专业学生分析问题习惯的研讨可视化的系统,提高学生讨论的效率。为了保证该系统符合用户的需要,该系统的设计过程采用以用户为中心的设计方法本论文的工作分为文献调研、用户研究与讨论模型提取、系统可视化设计和原型评估四个阶段。在文献调研阶段,主要了解目前关于法律讨论的相关理论、对话学习理论和信息可视化理论,这些理论作为本文研究的相关基础。在用户研究和讨论模型提取阶段,首先以访谈的形式了解用户讨论的一般习惯和使用论坛的一般情况,然后选取用户充分辩论的讨论内容,以Toulmin模型作为依据分析其中的讨论结构,提取讨论模型,并以焦点小组的形式加以评估和验证。在系统可视化设计阶段,以前期获得的用户需求和法律讨论模型为基础,结合信息可视化理论,设计最终的可视化界面和交互流程。最后阶段,用AXURE制作系统的高保真原型,以可用性测试的方式改进其可用性。此外,本尝试了以Flash和Asp.net为平台,构建系统的框架结构,并实现系统部分功能。在最终的评估中,用户在本系统上完成指定的任务,总体任务完成率达到98.8%,在应用论坛和本系统后对两者用户体验做出评价,本系统在有效性和主观满意度方面显著地高于论坛工具。一定程度上证明系统的有效性。结合本文的研究程,作者总结了将以用户为中心的设计方法应用于信息可视化的一般流程。
[Abstract]:The discussion of legal cases plays an important role in the study of professional knowledge of law students. At present, they mainly use the forum as a common tool for discussion, and as a tool for discussing legal cases, there is a high degree of repetition of views and confusion in the organization of statements. The lack of interactivity affects the efficiency of the discussion. The visualization of legal discussion information can improve the effectiveness of group communication and enhance the ability of users to process information. Although there are already many visualization systems for legal discussion, they are generally based on a certain mode of legal reasoning, which does not conform to the way of thinking of law students analyzing problems. Therefore, these research visualization systems are difficult to be widely used by law students. The author of this paper attempts to design a visualized system of discussion in accordance with the law students' habit of analyzing problems in order to improve the efficiency of students' discussion. In order to ensure that the system meets the needs of users, the design process of the system adopts the user-centered design method. The work of this paper is divided into literature research, user research and discussion model extraction. Visual design and prototype evaluation of the system are four stages. In the stage of literature research, we mainly understand the relevant theories of legal discussion, dialogue learning theory and information visualization theory, which are the relevant foundation of this paper. In the stage of user research and discussion model extraction, the general habits of user discussion and the general situation of using the forum are investigated in the form of interviews, and then the content of the discussion that is fully debated by the user is selected. Based on the Toulmin model, the discussion structure is analyzed, and the discussion model is extracted and evaluated and validated in the form of focus group. In the stage of system visualization design, the final visual interface and interaction flow are designed on the basis of user demand and legal discussion model obtained in the early stage, combined with the theory of information visualization. In the final stage, the high fidelity prototype of the system is made with AXURE, and the usability is improved by usability testing. In addition, based on Flash and Asp.net, the frame structure of the system is constructed, and some functions of the system are realized. In the final evaluation, the user completes the assigned task on the system, and the overall task completion rate reaches 98.8%. The user experience is evaluated after the application forum and the system. In terms of effectiveness and subjective satisfaction, the system is significantly higher than the forum tool. To some extent, the effectiveness of the system is proved. Combined with the research of this paper, the author summarizes the general process of applying the user-centered design method to information visualization.
