Vocabulary data report

Movie and episode vocabulary difficulty: a data report

The current website dataset can describe vocabulary coverage, entry types, definitions, and translations. It cannot yet support a public ranking of the easiest or hardest titles. This report publishes both findings with the same weight.

Publication status: this report is available for transparency but remains excluded from search indexing. A difficulty leaderboard will not be published until the source data can be independently reproduced, sample rules pass, and a named editorial approval is recorded.

Direct answer

The current source contains 200 movie and episode pages with 19,882 title-entry placements. Definitions are present for 100% of those placements, and translations across the eight learner languages are present for 100% of possible placement-language pairs.

Those facts describe the exported vocabulary inventory. They do not measure subtitle-token density, listening speed, comprehension, or a title's overall difficulty. Slovnyx therefore does not publish a movie ranking from this dataset alone.

What can be measured now

Inventory size
Page count, title-entry placements, distinct dictionary entries, and word-versus-phrase counts can be reproduced directly.
Definition and translation coverage
Coverage can be calculated as non-empty values divided by all expected values in the current export. Coverage does not prove that every definition or translation is pedagogically ideal.
Visible preview size
The website's server-rendered preview policy currently starts with 100 entries per title.

What is still missing for difficulty comparisons

  • A complete, reviewed occurrence denominator for every compared movie or episode—not only the words selected for display.
  • One validated familiarity or difficulty method applied to the entire comparison cohort.
  • Rules for minimum sample size, missing evidence, ties, and titles from different formats or runtimes.
  • A reproducible source plus recorded editorial approval for the exact published table.
A list of rare-looking words is not the same thing as a measured movie difficulty score.

Method and limitations

  1. Read the generated movie and episode page source used by this build.
  2. Count title-entry placements, distinct entry IDs, definitions, translations, and word-or-phrase classifications by format.
  3. Round coverage to one decimal place. Publish aggregate rows only; do not export dialogue, subtitle sequences, or private data.
  4. Fail closed on difficulty: no density or difficulty result appears when the required denominator is absent.

The snapshot covers the current web publication cohort, not all movies or television. Entries may repeat across titles. A title-entry placement is one entry attached to one title, so it is not the same as a unique word or a subtitle occurrence. Translation coverage is presence-only and does not replace native review.
