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。
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 down the scope of searching and quicken the retrieval of the target.
