A General Theory of Classificatory Sorting Strategies: 1. Hierarchical Systems
Abstract
It is shown that the computational behaviour of a hierarchical sorting-strategy depends on three properties, which are established for five conventional strategies and four measures. The conventional strategies are shown to be simple variants of a single linear system defined by four parameters. A new strategy is defined, enabling continuous variation of intensity of grouping by variation in a single parameter. An Appendix provides specifications of computer programs embodying the new principles.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
