Workshop 2: Cemantle

A word-guessing game using semantic similarity

What is Cemantle?

Cemantle is a game where you try to find a secret word. After each guess, you get a score showing how semantically close your word is to the target. The score is not based on spelling, but on meaning.

The game uses Word2Vec embeddings under the hood: the same technology we explored in TP1.

How to Play

1. Go to cemantle or its french counterpart cemantix
2. Type a word and submit
3. You'll get a similarity score (higher = closer to the target)
4. Use the feedback to narrow down your guesses
5. Find the secret word!

Tip: Start broad (common nouns, verbs) then get more specific as you get warmer.

Questions to Consider

• How does this connect to what you saw in the 2D embedding visualization?
• If two words have similar scores, does that mean they're similar to each other?
• Could you "cheat" by knowing how Word2Vec was trained?
