Lojban is a very precise language. It can be used as an intermediate language in machine translation tools. for example English <-> Lojban <-> Polish manual : https://lojban.org/publications/cll/cll_v1.1_xhtml-chapter-chunks/ has corpora https://corpus.lojban.org/ but need large parallel corpora It will be good if will possible integrate Abstract WIkipedia with Lojban as any more language,
