It is not a bloated NLP library. Instead, it focuses on basic stuffs such as sentence splitter and tokenizer, bigram statistical test, phrase extractor, keyword extractor, stemmer, POS tagging, relevance ranking. Combined with various machine learning algorithms e.g. HMM, maxent, CRF, etc., you can work out advanced applications such as sentiment analysis, named entity recognition, etc.
