Eighteen precomputed tables, each as CSV and JSON: root frequencies, dispersion and counts by surah, lemma frequencies, root-pair association statistics, per-surah stats, verse lengths and recitation durations, formulas and formulaic density, centrality, rhyme summary, fawātiḥ, direct address, discursive pivots, computed structure and its tests, and theme-surah density. Every field is documented in the schema and data dictionary below. For the complete raw pipeline (morphology, per-root files, and every other dataset this site ships), see Datasets.
Generated deterministically by
scripts/build-exports.mjs, which reads
data/roots-summary.json,
data/numbers.json,
data/chronology.json,
data/surah-profiles.json,
data/surah-names.json,
data/morphology/, and the association statistics from
data/association/*.json (written by
scripts/compute-association-stats.mjs). Run either
script twice and the output is byte-identical. Both scripts and
the full pipeline live in the
public repository.

Root frequencies ● ~
All 1,642 roots: raw count, overall normalized frequency (per 1,000 word-units), and per-period count and normalized frequency across the four revelation periods (Cairo 1924 / Nöldeke-Bell).
Root dispersion ●
All 1,642 roots: how evenly each is spread across the 114 surahs, weighted by surah size — Gries's DP, its Lijffijt & Gries normalization, Juilland's D, the count of surahs the root occurs in, and a dispersion-adjusted frequency. Four measures side by side rather than one, because the literature disagrees about which is best. Same figures as the Numbers table and the Roots root-detail panel.
Roots by surah ●
Every root in every surah it appears in: the count, and the rate per 1,000 of that surah's tokens, one row per root per surah. The full matrix behind the per-surah counts on the Roots detail panel, ready for a spreadsheet pivot or a heat map. A missing row means the root does not occur in that surah.
Lemma frequencies ●
Every lemma (dictionary headword) in the corpus: its count, part of speech, root if it has one, most common written form, how many distinct forms it takes, and how many verses and surahs it occurs in. The word-level companion to the root tables, and the list a vocabulary course would start from.
Direct address to the believers ●
Every verse containing yā ayyuhā lladhīna āmanū (“O you who believe”), matched on lemmas so inflected forms count. The list behind the vocative count on Patterns. Other vocatives are not included.
Verse durations ~
Every verse with its length in word-units and how many seconds its recitation lasts in each recording Read plays, one column per reciter. Measured from the audio files' headers; no audio is included. A duration describes one recording's performance, not the text. Summarized as pace on Numbers.
Association pairs ●
Root-pair association statistics (shared verses, LLR, PMI, Dice): the union of every pair appearing in any root's top-25-by-LLR partner list. Same formulas and thresholds as the Roots statistical-associations panel; see the schema for the exact counting rule.
Per-surah stats ● ~
All 114 surahs: verse/word-unit/root counts, vocabulary-diversity ratios, noun/verb percentage, and Cairo 1924 revelation order and period.
Verse lengths ●
Every verse in the corpus with its length in word-units and revelation period.
Formulas ●
Every recurring 3-5 word sequence in the Qur'an, root-view and
surface-view combined, with its first occurrence. Same counts
as Formulas; full occurrence lists are
in data/formulas-root.json and
data/formulas-surface.json.
Centrality ~
All 1,642 roots: degree, weighted degree, betweenness, and eigenvector centrality over the root co-occurrence graph, each with its rank. Same figures as the root detail centrality panel.
Rhyme summary ●
All 114 surahs: verse-ending rhyme family count, dominant key and share, shift count, top refrain, and mean run length. Same figures as the Patterns rhyme panel.
Fawatih ●
The 29 surahs opening with isolated letters (al-muqatta'at) and which of the 14 distinct combinations each uses. No meaning is asserted for the letters.
Discursive pivots ~
137 verses mechanically flagged for opening with a temporal particle while sharing a root with the previous verse, a candidate marker of where a passage turns, not a scholar's reading.
Computed structure ~
Mechanically segmented sections for all 114 surahs (417 sections total), a changepoint model over lexical cohesion, never attributed to any named scholar. See the Dossier "Computed structure" panel.
Structure tests ~
Four block-level mirror-symmetry tests over the computed sections, one row per surah. 0 of 345 candidates reached significance after correction; see Patterns.
Theme-surah density ~
Sparse theme-by-surah matrix: for each surah, the themes whose root-family vocabulary clusters most densely in it (theme-root word-units per 1,000 surah word-units). See Themes.
Schema and data dictionary
Every field, its unit, its counting rule, and its Verified/Nuanced status is documented in both a machine-readable schema and a prose data dictionary:
Everything at once, pinned to a version
One archive holds all eighteen tables in both formats, the schema, the data dictionary, and a citation file, so a download never travels without its provenance. The archive is named by release version and built deterministically: citing v1.3.0 names these exact bytes, and a new release adds a new archive rather than replacing this one. For toolchains that read standard packaging, the same tables are described as a Frictionless Data package and as Croissant JSON-LD.
divinediscourses-data-v1.3.1.tar.gz (all tables + schema + citation + corpus notice)
Earlier releases stay downloadable, because a published citation points at the bytes it was written against: v1.3.0, v1.2.0, v1.1.0, v1.0.0.
