Tóm tắt	Pile sorting is an elicitation technique in which informants are handed a set of cards — one per item in a cultural domain — and asked to group them into piles of items that 'go together.' By recording which items each person places in the same pile and aggregating across many informants, the researcher builds a similarity matrix that reveals how the culture organizes the domain, which is then visualized with multidimensional scaling and clustering.	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.
