SpråkpolisenBot is a reddit bot that corrects Swedish language errors on the subreddit /r/sweden. More specifically it targets incorrect usages of 'de' and 'dem'.
The bot uses a transformer neural network which was specifically trained to perform "token classification". The model was named DeFormer, as a word play on transformers and because it deforms instances of de and dem. DeFormer predicts each word piece (token) in a sentence in to one of three categories: ord, DE or DEM. Further details on the model powering SpråkpolisenBot can be found at the DeFormer repository.
