Hi As far as I know there is no portugese lemmatizer on official opennlp site. In general such models are not easily available, at least for less popular languages.
I developed an application to automatically compute sentence-detector, tokenizer, pos-tagger and lemmatizer from Universal Dependencies language files. For now models are generated for 19 languages (including portugese). Main app: https://github.com/abzif/babzel Pre-trained models: https://abzif.github.io/babzel/models.html Enjoy!
