Ethnoscience Taxonomy
Also known as: Folk Taxonomy, Ethnographic Semantics, New Ethnography Taxonomy, Folk Classification Analysis
Ethnoscience taxonomy is the ethnoscientific, or 'new ethnography,' approach to recovering how a culture classifies its world by eliciting the native terms of a domain and the inclusion and contrast relations that link them. Through structured interview questions — especially 'Is X a kind of Y?' and 'What kinds of Y are there?' — the researcher discovers which categories nest under which and which categories stand opposed at the same level. Organizing these relations produces a folk-taxonomic tree: a hierarchy of native categories built from the informants' own words rather than from scientific classification imposed from outside.
Key highlights
- Recovers classification in the informants' own categories and language, keeping the analysis fully emic.
- Reveals the hierarchical depth of folk knowledge that flat elicitation methods cannot show.
- Uses simple, replicable structural questions (inclusion and contrast) that travel well across cultures.
- Produces an interpretable taxonomic tree that integrates naturally with frame elicitation and pile-sort results.

When to use it
Use ethnoscience taxonomy when your goal is to describe how a culture itself classifies a domain — plants, animals, illnesses, kin, occupations — as a hierarchy of named categories in the people's own terms. It is the method of choice when emic accuracy and the structure of folk knowledge matter more than mapping items onto scientific categories. It assumes the domain is lexically rich and hierarchically organized and that informants share enough of the classification to elicit a coherent tree. It is less appropriate for domains that are dimensional rather than hierarchical, for thinly lexicalized domains with few native terms, or when you need quantitative similarity measures, for which pile sorting or triad tests are better suited.
Strengths & limitations
- Recovers classification in the informants' own categories and language, keeping the analysis fully emic.
- Reveals the hierarchical depth of folk knowledge that flat elicitation methods cannot show.
- Uses simple, replicable structural questions (inclusion and contrast) that travel well across cultures.
- Produces an interpretable taxonomic tree that integrates naturally with frame elicitation and pile-sort results.
- Assumes domains are organized as neat hierarchies, whereas many folk classifications are partial, overlapping, or cross-cutting.
- Heavily dependent on a few skilled informants, so individual idiosyncrasy can masquerade as shared structure.
- Labor-intensive interviewing makes large samples and broad coverage costly.
- Yields qualitative structure rather than quantitative similarity, limiting statistical comparison.

Frequently asked
What is the difference between a taxonomy and a contrast set?
A taxonomy is the whole nested hierarchy of categories linked by 'is a kind of' inclusion relations, from a broad cover term down to specific kinds. A contrast set is a single horizontal layer within it: the group of mutually exclusive categories that are all kinds of the same superordinate term and that contrast with one another. The taxonomy stacks contrast sets vertically through levels of inclusion.
How does ethnoscience taxonomy relate to frame elicitation?
They are complementary parts of the same tradition. Frame elicitation, using substitution frames such as 'Is X a kind of Y?', supplies the inclusion and contrast judgments that the taxonomy is built from, while componential analysis identifies the features that distinguish sibling categories. Ethnoscience taxonomy organizes those judgments into the hierarchical tree; frame and componential analysis explain why categories sit where they do.
Is a folk taxonomy the same as a scientific classification?
No. A folk taxonomy reflects how a particular culture names and nests categories in its own terms, which may group or split organisms quite differently from scientific (Linnaean) taxonomy and may rely on use, appearance, or cultural significance rather than biological descent. The method deliberately keeps the analysis emic, so the resulting tree is a model of native classification, not a correction of it.
