This document summarizes a presentation on the OpenNLP toolkit. OpenNLP is an open-source Java toolkit for natural language processing. It provides common NLP features like tokenization, sentence segmentation, part-of-speech tagging, and named entity extraction. The presentation discusses how these features work using pre-trained models for different languages. An example is also given showing how OpenNLP could be used to extract tags from a website and display them in a tag cloud. The presentation concludes by providing contact information for the presenter.
