Purpose: The purpose of this article is to propose, based on a model of an interaction semantics, a certain understanding of the ''meaning'' of the exchanged characters within an interaction. Methodology: Based on a model of system interaction, I structure the model of interaction semantics similar to the semantics of a formal language: first, I identify adequate variables in my interaction model to assign values to, and second, I identify the interpretation function to provide meaning. Thereby I arrive at a model of interaction semantics which, in the sense of the late Ludwig Wittgenstein, can do without a 'mental' mapping from characters to concepts. Findings: The key findings are a better understanding of the tight relation between the informatical approach to model interactions and game theory; of the central 'chicken and egg' problem, any natural language has to solve, namely that to interact sensibly, we have to understand each other and to acquire a common understanding, we have to interact with each other, which I call the 'simultaneous interaction and understanding (SIAU)' problem; why ontologies are less 'semantic' then their proponents suggest; and how 'semantic' interoperability is to be achieved. Value: The main value of the proposed model of interaction semantics is that it could be applied in many different disciplines and therefore could serve as a basis for scientists of natural sciences and humanities as well as engineers to understand each other more easily talking about semantics, especially with the advent of cyber-physical systems.

翻译：目的：本文旨在基于交互语义学模型，提出对交互中交换字符"意义"的特定理解。方法：基于系统交互模型，我构建了类似于形式语言语义学的交互语义学模型：首先，在我的交互模型中识别适当的变量以赋值；其次，识别解释函数以提供意义。由此，我得出一个交互语义学模型，该模型在路德维希·维特根斯坦晚期的思想意义上，无需从字符到概念的"心智"映射。发现：关键发现包括：对建模交互的信息学方法与博弈论之间紧密联系的更深入理解；任何自然语言都必须解决的核心"鸡与蛋"问题——即要合理交互，我们必须相互理解，而要获得共同理解，我们又必须相互交互（我称之为"同步交互与理解(SIAU)"问题）；本体论为何不如其支持者所声称的那般具有"语义"性；以及如何实现"语义"互操作性。价值：所提出的交互语义学模型的主要价值在于可广泛应用于众多不同学科，因此可作为自然科学、人文学科科学家以及工程师在讨论语义学（尤其是在网络-物理系统兴起的背景下）时更容易相互理解的基础。
