Rank-word lexicon, JournalistLabs.
Matched over the job title only, lowercased, whitespace collapsed, & read as and.
A word is in the lexicon when it puts the holder above or below a plain title.

NARROW SET — the report's set. Every count, share and ranking uses it.
  senior       \b(senior|snr|sr\.?)\b
  head of      \bhead\s+of\b
  director     \bdirector\b
  chief        \b(chief|editor[\s\-]in[\s\-]chief)\b
  deputy       \bdeputy\b
  executive    \b(executive|exec)\b
  lead         \blead\b
  vp           \b(vp|vice\s+president)\b
  principal    \bprincipal\b

WIDE SET — the narrow set plus the two words below. Reported in the wide_* columns
as a second reading; never used to rank.
  head (bare)  \bhead\b
  managing     \bmanaging\b

junior words, counted in their own columns and never part of the rank count
  assistant    \b(assistant|asst\.?)\b
  associate    \b(associate|assoc\.?)\b
  junior       \b(junior|jr\.?)\b
  trainee      \b(trainee|apprentice)\b

any rank word = a narrow rank word or a junior word.

English job-noun test, used in the language check
  \b(editor|reporter|journalist)\b

Language check rule: a title counts when it carries no narrow rank word and
no English job noun. No country list and no junior word is used.
