UD for Luxembourgish 
Tokenization and Word Segmentation
- Words are generally delimited by whitespace characters.
- According to typographical rules, many punctuation marks are attached to a neighboring word.
We usually tokenize them as separate tokens (words)
with the exception of:
- The determiner d’ “the” is kept as one token with the apostrophe.
- Abbreviations which are kept as one token with the period.
- Luxembourgish compounds are written as one word and we do not split them.
- There are two classes of multi-word tokens:
- The contractions of prepositions and definite articles. (Example: vum = vun + dem “from the”.)
- Univerbation due to main verb with verb particle. (Example: opzehalen = ze + ophalen “to stop”.)
