项目摘要

We conducted a preliminary research to construct a cognitive semantic interpretation theory for action verbs based on a formal model as follows :1. A new semantic model was proposed in which each individual is defined as a set forming a volume shifting in a temporal space. Focusing on the subsets of an individual performing an action, its parts involved in each interval were abstracted for the semantic definition of the relevant action verb, i.e. the name for that action. With these, we were enabled to describe an action complex spatiotemporally.2. An interpretive theory for action verbs based on spatiotemporal model was proposed (Nishina '98). To define an action verb, we proposed a sequence of feature sets referring to the parts involved in the action denoted by the verb. An algorithm using a feature sequence was devised for deciding which action is contained in a complex of movements. Several interpretive rules reflecting this algorithm was also defined.3. This model is being further refined as a wire-frame model and its effectiveness was discussed (Nishina '00). The skeleton of an individual was described in a wire frame and its movements were shown to be expressed in rotation formulae, which describe each point as rotating round some axis. Complex action structure was achieved by converting these formulae to individual functions on axis. We confirmed that by comparing this structure with some operations added on it with the defining sequence for an action verb, we can decide if that complex contains the action whose name is that verb. Thus, this model proved to be a test bench for a cognitive formal model for semantic interpretation.

我们进行了初步研究，构建了基于形式模型的动作动词认知语义解释理论：1．提出了一种新的语义模型，其中每个个体被定义为在时间空间中形成体积移动的集合。关注执行某个动作的个体的子集，将每个区间涉及的部分抽象为相关动作动词的语义定义，即该动作的名称。有了这些，我们就能够在时空上描述一个复杂的动作。2．提出了一种基于时空模型的动作动词解释理论（Nishina '98）。为了定义动作动词，我们提出了一系列特征集，指的是动词所表示的动作所涉及的部分。设计了一种使用特征序列的算法来确定复合运动中包含哪个动作。还定义了反映该算法的几个解释规则。 3．该模型正在进一步细化为线框模型，并讨论了其有效性（Nishina '00）。个体的骨骼是用线框来描述的，其运动用旋转公式来表达，该公式将每个点描述为绕某个轴旋转。通过将这些公式转换为轴上的单独函数来实现复杂的动作结构。我们确认，通过将该结构与添加在其上的一些操作与动作动词的定义序列进行比较，我们可以确定该复合体是否包含名称为该动词的动作。因此，该模型被证明是语义解释认知形式模型的测试平台。
