What exactly is considered a constrained submission? Can we use e.g. lexicons, embeddings, clusteres, sentiment labels etc. ?
Thanks for answer.

This has been addressed several times in the Google group of the task as well. Constrained systems are *only* trained on the provided data for this task, whereas for unconstrained systems additional training data (e.g. collected and annotated by the participants themselves) were used. The constrained/unconstrained distinction only applies to the training data, not to data used for feature engineering, i.e. constrained systems can make use of additional resources like lexicons, dictionaries, embeddings...
Kind regards
