We describe an activation-based model of word recognition and apply it to the process of resolving the meaning of homographs presented in context. The interpretation of homographs was assessed by asking participants to decide whether a target word was related to the meaning of a sentence containing a homograph. These relatedness decisions varied systematically with the relative frequency of the homograph meanings, delay, and the nature of the sentence context. In the model, it was assumed that orthographic and contextual information combine additively to determine the activation of word meanings, and that the probability of a "related" response is determined by the activation level of the related meaning. The model accurately accounts for all observed effects, as well as their interaction. We conclude that the core process of lexical ambiguity resolution may be quite simple.
我们描述了一种基于激活的单词识别模型，并将其应用于解决语境中同形异义词含义的过程。通过要求参与者判断目标单词是否与包含同形异义词的句子的含义相关，来评估对同形异义词的解释。这些相关性判断随同形异义词含义的相对频率、延迟以及句子语境的性质而系统地变化。在该模型中，假设正字法和语境信息相加结合以确定单词含义的激活，并且“相关”反应的概率由相关含义的激活水平决定。该模型准确地解释了所有观察到的效应及其相互作用。我们得出结论，词汇歧义消解的核心过程可能相当简单。
