【摘要】 学习外语的过程就是一个范畴化的过程,范畴化的结果就是心理词库在学习者头脑中的形成。因此了解心理词库的内在组织结构并运用它来指导我们的词典编纂就变得非常重要了。 经过认真研究我们认为心理词库的组织结构是词汇语义网络。我们试图运用这种词汇语义网络来指导我们的词典编纂,然而由于纸质词典版面和技术手段有限,我们发现难以在纸质词典中构建完整的词汇语义网络。幸运的是,随着现代计算机技术的发展,我们可以在电子词典中构建这样一个相对比较完善的词汇语义网络。 构建了一个词汇语义网络的电子词典,看上去似乎是一个字母排序词典和分类词典的组合。我们的研究表明,它超越了字母排序词典,也超越了分类词典,甚至不只是将两者结合那么简单。它构建的外部网络涉及到语义关系、语音关系和形态关系,这对于学习者词汇的意义理解和词汇推理能力的提高非常重要。它也构建了一个内部网络,解决了长期以来义项排列不能同时兼顾历史顺序、逻辑顺序、词频顺序和查询效率的问题。 本研究是在语言学、心理语言学、词典学和计算机技术等跨学科理论的共同指导下进行了一系列的创新,同时保持词典原有优势和特色。从理论上提出了在双语词典中构建语义一词汇网络的理念,并且较好地解决了长期以来没有得到解决的义项排序死结,对于未来电子词典的发展提供了较好的理论支持和实践尝试。更多还原

【Abstract】 The process of learning a foreign language is a process of categorization. The result of categorization is to form a mental lexicon in language learner’s mind. So it is very important to know the organization of the mental lexicon so as to provide guidance for our bilingual dictionary compilation.After a careful study we propose that in linguistics the organization of the mental lexicon is represented as a lexical-semantic network. Then we try to use this to guide our dictionary compiling. However, it is very difficult to set up a lexical-semantic network in printed dictionaries because of their limited space and technology. Luckily, with the development of the modern computer technology we can construct a comparatively good lexical-semantic network in the electronic dictionary.The dictionary provided with a lexical-semantic network seems to be a combination of dictionary and thesaurus, but in fact it is more than this. For it consists of an external network as well as an internal network. The former involves the semantic relations and the morphological relations which are very important to comprehend a word and to form the vocabulary referential ability. The latter aims at improving the sense arrangement which has been a tough problem for lexicography.Dictionary users can greatly benefit from such a dictionary. First, they can comprehend a word within a frame so that they can acquire comprehensive knowledge of the lexeme. Secondly, it may facilitate users’ categorization of different entities and concepts. Thirdly, it provides favorable situation for users to enlarge their vocabulary.In brief, the research aims to set up a lexical-semantic network in learner’s dictionary on the basis on a theoretical study of the mental lexicon and the semantic structure as well as prototypical categorization, which would greatly facilitate the FFL acquisition for Chinese learners.更多还原
