خلاصه	The sentence-frame substitution task is a frame-elicitation technique in which the researcher builds a small set of sentence frames — templates such as 'Can you get X from Y?' or 'Is X a kind of Y?' — and asks informants to judge, for each item and each frame, whether the completed sentence is true or sensible. Each item is slotted into every frame in turn, and the yes/no verdicts are tallied into an item-by-attribute matrix. That binary matrix is the raw material for componential and ethnoscience analysis, which uncovers the features that distinguish the items of a cultural domain.	The triad test is an elicitation technique for measuring perceived similarity among the items of a cultural domain. Informants are shown items three at a time and asked to pick the one that is most different (or, equivalently, which two are most alike). Across many triads and many informants, the pattern of which items are repeatedly kept together yields a fine-grained similarity matrix that is analyzed with multidimensional scaling and clustering.
