List of symbols

En français · по-русски

This page lists the symbols in Apertium used to denote part-of-speech and further morphological features, as well as chunk tags used for more syntactic functions, as well as XML tags.

This page also documents alignment between Apertium morphological tags and Universal Dependencies POS tags and features.

This is meant to be a glossary of symbol names in alphabetical order with notes. Some of these names are specific to particular packages or language pairs, as not all languages have the same grammatical features (most don't have spatial distinction in articles for example).

If you were wondering what the symbols #, /, @, +, ~ or * mean, read Apertium stream format.
