HPS: High Precision stemmer

HPS is a multilingual stemming tool based on unsupervised training from unlabeled corpora. HPS proved state-of-the-art performance on several tasks (e.g., Named Entity Recognition, Sentiment Analysis, Language Modeling, Information Retrieval) and in many languages. More technical details can be found in our paper (see [Brychcín and Konopík, 2015]) that has been accepted to the Information Processing and Management journal.
