We invite participants to benchmark systems for word sense induction (WSI) across multiple languages. Unlike traditional approaches, this task evaluates WSI without relying on predefined sense inventories, offering a more theoretically plausible framework for understanding word meanings.

Participants will be provided with:

• A set of polysemous target headwords.
• Sentences containing these words in diverse contexts.

The goal is to cluster the sentences according to the sense in which the target word is used.

A different set of headwords and contexts will be provided for each of the following languages: English, Czech, German, Spanish, Estonian, Chinese

For each language, there will be approximately 25 headwords with 1500+ contexts each.
