The Stanford API supports several classifiers. We will examine the use of the ColumnDataClassifier class for general classification and the StanfordCoreNLP pipeline to perform sentiment analysis. The classifiers supported by the Stanford API can be difficult to use at times. With the ColumnDataClassifier class, we will demonstrate how to classify the size of boxes. With the pipeline, we will illustrate how to determine the positive or negative sentiment of short text phrases. The classifier can be downloaded from http://www-nlp.stanford.edu/wiki/Software/Classifier.
