N-grams for Polish - how to build a Lucene database?

1

There’s a 7 GB zip file with a set of n-grams for Polish created by the Wrocław University for Science and Technology, with a CreativeCommons BY-SA 4.0 license. It has 2-grams, 3-grams and even some 4-grams, but they’re all in .txt format, as tables of words.

How do I convert this into a lucene database usable by LanguageTool?

You might find background information at Finding errors using Big Data - LanguageTool Wiki. Please be aware that having ngrams available won’t do anything - making use of the in LT requires significant investment besides building the ngram data.
