Simulating Food Evacuation Behavior : An application of Quasi-isomorphic Knowledge Model

本研究旨在建立一个仿真模型，模拟洪水突发事件下市民个体疏散行为的决策过程。本研究包括三个部分：第一年，利用视频图像构建实验情境，对20名被试进行虚拟洪水疏散体验，并对被试的行为进行分析，以确定被试的决策过程。并记录了出声思考的过程，以揭示他们的决定是什么，以及他们是如何做出这些决定的。从协议中提取与疏散决策相关的命题。大多数有声思维协议都是类似于口语的畸形句子。此外，日语中的命题还附有各种情态表达。针对这两种歧义产生的原因，我们提出了一种分离情态和命题的方法， ...更多信息 第二年，运用句子的功能分类法，将行为命题和事实命题区分开来。在此基础上，对疏散行为进行了分类，包括信息收集、疏散准备、通信和疏散。结果表明，及物动词的意义可以分析使用情况限制，从而使相应的及物动词检测到的四个类别。与预期相反，意义分析不需要语用解释，可能是因为决策上下文是固定的，就像本研究一样。命题的三个不同方面被确定：1）时间框架，2）对象的案例相关性，和3）描述形式。最后，将上述检测到的事实规则和行为规则建模到模拟器中，并成功地模拟了经验主体和非经验主体之间的差异。少

The purpose of this study is to build a simulation model to emulate decision process of individual citizens' evacuation behaviors in the face of flood emergency. The study consists of three parts : 1)protocol experiment for collecting think aloud protocol, 2)detecting factual-inference rules and behavioral rules from the recorded protocol, and 3)simulate the decision process.In the first year, an experimental setting was constructed by using video image to give virtual flood evacuation experiences to the 20 subjects, and recorded the think aloud protocol to reveal what are their decisions and how they come about such decisions. From the protocol, the propositions related to evacuation decision are extracted. Most of think aloud protocols are ill-formed sentences similar to spoken language. Besides that, various modality expressions are attached to proposition in Japanese. To deal with these two causes of ambiguity, we developed a method to separate modality and proposition and a method … More to transform ill-formed sentence to well-formed sentence.In the second year, behavioral propositions and factual propositions are separated using the functional classification of sentence. Then four categories of evacuation behaviors, information gathering, preparation of evacuation, communication, and evacuation, are detected. It is shown that the meaning of transitive verves can be analyzed using case restriction, thus enabling to correspond transitive to the four categories detected. Against the expectation, the meaning analysis does not require pragmatic interpretation, probably because the decision context is fixed like in this study.In the final, third year, factual propositions are analyzed. Three different aspects of propositions are identified : 1)time frame, 2)case relatedness of objects, and 3)descriptive forms. Finally, the factual rules and behavioral rules detected above are modeled into a simulator and can emulate successfully the difference between the experienced subjects and the non-experienced subjects.
