| 摘 要： | 语义网络是模拟人脑记忆的知识表征系统,记忆中的概念通过关系结构互相连接,主要有分层结构、主题分类、并列结构、搭配等等.在扩散性语义网络模型中,词义检索始于激活一个概念节点,相关的其他概念继而平行激活,特定方向的激活一定程度上是串行的.语义网络的关系结构影响词义检索.意义关系是主要的语义提示,能缩小潜在的搜索范围,加快识别目标词.

| Abstract: | The semantic network is a system of knowledge representation simulating the memory.Concepts in the memory are connected through relational structures: hierarchical structure,thematic categorization,coordination,etc.In the spreading semantic network,semantic retrieval starts by activating a concept and activation spreads in all directions in parallel,with serial activation in some particular directions.The relational structures affect semantic retrieval.Semantic relations serve mainly as primes which narrow ... |
