LingPipe 3.1.0 has some important bug fixes: small set generics, dictionary chunker case sensitivity, and dictionary training of chunkers.
There are new classifiers (Perceptron, K-nearest-neighbor and TF/IDF) and a new clusterer (K-means) based on a new feature extraction interface and vector distances.
There are also some new tutorial sections: chunking text into noun phrases and verb phrases, and dictionary-based entity extraction.
