Dear all,

After a successful first edition in 2021, we are glad to invite you to the second MultiLexNorm shared task! The shared task will be hosted at WNUT 2025.

As defined in the previous iteration, lexical normalization is: The task of transforming an utterance into its standard form, word by word, including both one-to-many (1-n) and many-to-one (n-1) replacements.

Building on the previous task which focused on Indo-European languages written in the Latin script, we extended the benchmark to include languages written in other scripts. We now include data for Thai, Vietnamese, and Indonesian. The data and more information about the task can be found on:
