Reading the signal · The weighting · Element

The frequency

How often the theme appears.

The part

What it is

Counted from the coded set, as a share of respondents rather than of comments, since one person can raise a theme three times.

Tracked across periods, since a theme rising is more informative than a theme being common.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
