摘要	Appraisal analysis is the systematic study of evaluative language — how speakers and writers express feelings, make judgements, value things, take a stance toward other voices, and turn the volume of their evaluations up or down. Developed by James Martin and Peter White within the interpersonal metafunction of systemic functional linguistics, the appraisal framework codes evaluative meaning along three systems: ATTITUDE (the kinds of feeling expressed), ENGAGEMENT (how the text positions itself among alternative voices and viewpoints), and GRADUATION (how evaluations are intensified or softened, sharpened or blurred). The method makes the often-invisible work of evaluation explicit, showing how texts construe stance and build alignment with their readers.	Corpus-Assisted Discourse Studies (CADS) is a mixed-methods approach that combines the quantitative power of corpus linguistics with the interpretive depth of discourse analysis to investigate how meanings, evaluations, and ideologies are constructed across large collections of text. Pioneered by Alan Partington and colleagues, CADS uses corpus techniques such as keyness, collocation, and concordancing to identify patterns no analyst could find by reading alone, then 'shunts' back to close qualitative reading to interpret what those patterns mean in their discursive context.
