English Wiktionary Parsed Data

Structured linguistic data extracted from the English Wiktionary dump into JSONL. Even though it's the "English" Wiktionary, it is not limited to English, that is just one of many many languages it supports, but definitions are in English.

Covers definitions, IPA pronunciations, etymologies, translations, inflection tables, derived/related terms, synonyms, antonyms, descendants, and more across over a thousand languages.

Contents 

base/
  language.json
  string/
    english.jsonl
    hebrew.jsonl
    tibetan.jsonl
    sanskrit.jsonl
    chinese.jsonl
    greek.jsonl
    latin.jsonl
    arabic.jsonl
    ...
  • string/<language>.jsonl has one JSONL file per language. Records are sorted alphabetically by the string field.
  • language.json lists every language as { slug, name }, sorted alphabetically by name.

They are called "strings" b/c they can be not just words, but prefixes/suffixes/affixes, letters, multi-word terms, phrases, etc..

Usage 

from datasets import load_dataset

strings = load_dataset("cluesurf/wiktionary-english", "string") # default
languages = load_dataset("cluesurf/wiktionary-english", "language")
