Formality Considered Harmful: Experiences, Emerging Themes, and Directions on the Use of Formal Representations in Interactive Systems 总被引:1,自引:0,他引:1
Frank M. Shipman III Catherine C. Marshall 《Computer Supported Cooperative Work (CSCW)》1999,8(4):333-352
This paper reflects on experiences designing, developing, and working with users of a variety of interactive computer systems. The authors propose, based on these experiences, that the cause of a number of unexpected difficulties in human-computer interaction lies in users' unwillingness or inability to make structure, content, or procedures explicit. Besides recounting experiences with system use, this paper discusses why users reject or circumvent formalisms which require such explicit expression, and suggests how system designers can anticipate and compensate for problems users have in making implicit aspects of their tasks explicit. The authors propose computational approaches that address this problem, including incremental and system-assisted formalization mechanisms and methods for recognizing and using undeclared structure; they also propose non-computational solutions that involve designers and users reaching a shared understanding of the task situation and the methods that motivate the formalisms. This paper poses that, while it is impossible to remove all formalisms from computing systems, system designers need to match the level of formal expression entailed with the goals and situation of the users -- a design criteria not commonly mentioned in current interface design. 相似文献

一种基于静态词法树的程序相似性检测方法* 总被引:1,自引:0,他引:1
传统的程序相似性检测工具并不能有效地检测出一些常见的高级词法、语义理解变换的抄袭方式。首先归纳了学生常用的三类抄袭手段,然后给出了基于词法树的程序相似性检测方法。以C语言为例,总结了生成词法树的结构体,并对程序的词法树进行主数据流、结构控制流和时序流分析后得出结构体依赖图;使用形式化的图同型方法来判断代码是否相似,还给出了一个聚类方法以获得彼此相似的程序子集。通过与JPlag、BuaaSim系统针对一组典型的抄袭样本集进行评测结果对比,本方法具有更好的检测效果。 相似文献

风景旅游历史文化的时空物化——梁祝文化村策划规划构思 总被引:3,自引:0,他引:3
随着我国度假休闲热的兴起,许多地方都在积极开发建设风景旅游区。在风景旅游区的规划设计中如何充分挖掘其历史积淀和文化内涵,并运用景观规划设计手段加以物化,塑造了特色鲜明的风景旅游形象,这是具有普遍意义而又难以把握的难题。本文以梁祝文化村(上虞市洪山湖旅游度假村)策划规划为例,试图就此作一初步探讨。 相似文献

Facility inspection is crucial for ensuring the performance of built assets. A traditional inspection, characterized by humans’ physical presence, is laborious, time-consuming, and becomes difficult to implement because of travel restrictions amid the pandemic. This laborious practice can potentially be automated by emerging smart technologies such as robotics and building information model (BIM). However, little has been known on how such automation can be achieved, concerning the knowledge-intensive nature of facility inspection. To fill the gap, this research aims to develop a knowledge-driven approach that can synergize knowledge of diverse sources (e.g., explicit knowledge from BIM, and tacit experience in human minds) to allow autonomous implementation of facility inspection by robotic agents. At the core the approach is an integrated scene-task-agent (iSTA) model that formalizes engineering priori in facility management and integrates the rich contextual information from BIM. Experiments demonstrated the applicability of the approach, which can endow robots with autonomy and knowledge to navigate the challenging built environments and deliver facility inspection outcomes. The iSTA model is publicized online, in hope of further extension by the research community and practical deployment to enable automated facility inspection using robotics and BIM. 相似文献
