We need a database of synonyms. Are there any free resources to download?

Question

Computational linguistics

To work, you need bases (text lists) of synonyms, antonyms, paronyms. The more entries, the better. But at the same time, it is desirable that there be some kind of systematization and without unnecessary garbage. There are resources where you can find a synonym for a given word, but in order to get everything at once and for free, I haven’t seen something. Maybe someone met such a linguistic Eldorado?

Answer 1

https://www.wiktionary.org/ not for download, but no one bothers to parse as needed
