title: NLP - Sentence Segmentation
body: <p>I am a newbie trying my hands on sentence segmentation in NLP.
  I am aware tokenizers are available for the same in NLTK. But I wanted to build my own sentence segmenter using Machine Learning algorithm like Decision Tree. But I am not able to gather training data for it. How should be the data. How should it be labelled, since I wanted to try first using supervised learning. Any sample data already available? Any help will be useful. I searched in net for nearly a week and now posting the same for help. Thanks in advance.</p>
