语言学语域的学术词组研究

在总结语言学语域249个常用学术词组后,发现它们与AFL的差别源于后者包括大量的自然科学语料、偏重于FTW、在同义词词组选择上有不同的偏好。在语言学语域内部,词典比教材更接近AFL,更多地指向背景的抽象框架属性、偏重于时空指示、多用同位结构、突出对信息本身的呈现、通过联想拓宽知识面、呈现给读者更多的学术资源而不是总结差异、更多地使用被动结构、不挑明较深层的因果关系而是由读者自己去领悟和发现。

学术词组中词汇语法连续体的双向互动研究

本文以学术词组库(Academic Formulaic List)中的407个学术词组为基础,运用型式语法(Pattern Grammar)和构式语法(Construction Grammar)的研究方法,发现学术词组的内部结构具有连续体特征,词汇、语法和准构式(mid-level construction)构成从简单到复杂的连续体,互动模式包括连续体两端的双向互动,以及中间环节对连续体两端的衔接与互动。互动源于连续体各环节内部以及三个环节之间各种力量的动态作用。
