内容摘要

根据学习即范畴化的认知规律和心理词库的相关研究成果,词汇学习是新旧知识的联结,这种联结包括词汇之间形似、音似和语义关系的联结。人们已习得的词汇,是以类似网络的形式,存储在大脑中,而不是像词典中的词汇,以字母顺序来排列。其中词汇语义网络被认为是目前反映心理词库组织最理想的模型。在词汇语义网络中,词用接点来表示,接点和接点之间通过词的形似、音似和各种语义关系而相互连接。接点之间的距离由词汇之间联结程度的强弱决定。由于词汇的学习不仅仅是学习新词汇,更是学习词汇之间的各种关系,因此,在学习词典中应用词汇语义网络提供词汇的各种关系将大大有利于学习者的词汇习得。然而,纸质词典由于空间和技术的限制,很难提供完善的词汇语义网络,无论是按照字母编排还是按照概念编排的词典在提供词汇语义网络方面都存在不足之处。电子词典由于其自身的优势,例如几乎没有空间限制,多方式搜索,可应用超链接、多媒体等技术,可以提供较为完善的词汇语义网络。事实上,英国五大学习词典(光盘版)在这方面已经有了卓有成效的尝试。而国内研制的英汉电子词典则在提供词汇语义网络方面远远不足。与此相关,一些研究已经提出在阅读和词汇教学中应用语义网络的成果,但这些研究主要是探索如何在课本教学中根据图式理论构建词汇的宏观网络,很少涉及词汇之间由于形似、音似和各种语义关系构成的词汇语义网络。研究在英汉双语词典中应用词汇语义网络及其具体编纂方法的更是少有提及。因此,本文在语言学、心理语言学、词典学和计算机技术等学科的相关理论共同指导下,改进当前的词汇语义网络的语音、形态和各种语义关系,据此分析和借鉴英国五大学习词典(光盘版)提供词汇语义网络的方式,探讨如何在英汉电子词典中体现较为完善的词汇语义网络,并提出具体的编纂建议和实例。
