This project collects a number of core libraries for Natural Language Processing (NLP) developed by Cognitive Computation Group.

CogComp's main NLP libraries

Each library contains detailed readme and instructions on how to use it. In addition the javadoc of the whole project is available here.

Module	Description
nlp-pipeline	Provides an end-to-end NLP processing application that runs a variety of NLP tools on input text.
core-utilities	Provides a set of NLP-friendly data structures and a number of NLP-related utilities that support writing NLP applications, running experiments, etc.
corpusreaders	Provides classes to read documents from corpora into core-utilities data structures.
curator	Supports use of CogComp NLP Curator, a tool to run NLP applications as services.
edison	A library for feature extraction from core-utilities data structures.
lemmatizer	An application that uses WordNet and simple rules to find the root forms of words in plain text.
tokenizer	An application that identifies sentence and word boundaries in plain text.
transliteration	An application that transliterates names between different scripts.
pos	An application that identifies the part of speech (e.g. verb + tense, noun + number) of each word in plain text.
ner	An application that identifies named entities in plain text according to two different sets of categories.
md	An application that identifies entity mentions in plain text.
relation-extraction	An application that identifies entity mentions, then identify relation pairs among the mentions detected.
quantifier	This tool detects mentions of quantities in the text, as well as normalizes it to a standard form.
inference	A suite of unified wrappers to a set optimization libraries, as well as some basic approximate solvers.
depparse	An application that identifies the dependency parse tree of a sentence.
verbsense	This system addresses the verb sense disambiguation (VSD) problem for English.
prepsrl	An application that identifies semantic relations expressed by prepositions and develops statistical learning models for predicting the relations.
commasrl	This software extracts relations that commas participate in.
similarity	This software compare objects --especially Strings-- and return a score indicating how similar they are.
temporal-normalizer	A temporal extractor and normalizer.
dataless-classifier	Classifies text into a user-specified label hierarchy from just the textual label descriptions
external-annotators	A collection useful external annotators.
