科学子语言根据话语社区（DC）的需求而发展，新词被创造出来，并且通过现有词汇表达的含义逐渐发生变化。就中心概念相互关联而言，相似的关系模式出现在它们的表面结构、词语中。因此，给定词汇项的“参考框架”可以在该单词的特定流派词汇环境中找到。这是通过搭配揭示的，使用互信息统计来衡量。进一步假设科学子语言的概念框架可以通过封闭组搭配网络来可视化。这些网络可以通过有向图在本地进行演示，但网络被认为是一种更合适的方式来演示各个项目之间关系的复杂性。搭配网络被视为形成给定子语言中任何“单词”的独特参考框架
Scientific sublanguages evolve in accordance with the needs of the Discourse Community (DC) with new words being coined and a gradual change in the meanings expressed through existing lexis. In so far as the central concepts relate to each other, similar relational patterns emerge in their surface constructs, words. Consequently, the "frame of reference" for a given lexical item is to be found in the genre-specific lexical environment of that word. This is revealed through collocation, as measured using Mutual Information statistics. It is further posited that the conceptual frameworks of scientific sublanguages can be visualised through closed set collocational networks. These networks may be demonstrated locally through digraphs, but the network is posited as a more suitable means of demonstrating the complexity of relationships between individual items. The collocational networks are seen as forming the unique frame of reference for any "word" within a given sublanguage
