Natural Language Generation Systems

AutoSummary uses Natural Language Processing to generate a contextually-relevant synopsis of plain text. It uses statistical and rule-based methods for part-of-speech tagging, word sense disambiguation, sentence deconstruction and semantic analysis. Platforms: Windows, Mac, Linux

Butler is a program that can take natural language input and search for the information that the user wants. It is in C# .NET. For example, the user might say 'Tell me about the Grand Canyon.' The program would say, 'The Grand Canyon is in Arazona.' Platforms: Windows, Mac, Linux

J2SE implementation of the Dictionary Server Protocol (DICT) that allows a client to access dictionary definitions from a set of natural language dictionary databases. Platforms: Windows, Mac, Linux

The EPAL Editor allows users to specify complex EPAL privacy policies using natural language constructs through a GUI interface. Platforms: Windows, Mac, Linux

Example-based Development of Grammars (EDG) is a system implemented in Lisp for building natural language grammars andlexicons incrementally and interactively. Platforms: Windows, Mac, Linux

The Helsinki Finite-State Transducer toolkit is intended for processing natural language morphologies. The toolkit is demonstrated by wide-coverage implementations of a number of languages of varying morphological complexity. Platforms: Mac, Linux

HERAKLES is a reasoning broker framework for OWL (Web Ontology Language) reasoning systems. Platforms: Windows, Mac, Linux

The JINSECT toolkit is a Java-based toolkit and library that supports and demonstrates the use of n-gram graphs within Natural Language Processing applications, ranging from summarization and summary evaluation to text classification and indexing. Platforms: Windows, Mac, Linux

MutationFinder is a biomedical natural language processing (NLP) system for extracting mentions of point mutations from free text. MutationFinder achieves high performance (99% precision, 81% recall on blind test data) as an information extraction system Platforms: Windows, Mac, Linux

The nlpFarm is a Natural Language Processing (NLP) resource where early research prototypes (Java) can evolve into robust and useful open source. Our farmstead collaborates under the OpenNLP initiative, in order to make NLP software publically available. Platforms: Windows, Mac, Linux

Nalasys is a natural language system that allows users to specify instructions to the computer in natural language. By defining words with intrinsic data the system recognizes, a user will be able to program a system using his own words. For now the system can use several programmatic languages... Platforms: Windows, Mac, Linux

OpenCCG, the OpenNLP CCG Library, is a collection of natural language processing components and tools which provide support for parsing and realization with Combinatory Categorial Grammar (CCG). Platforms: Windows, Mac, Linux

OpenNLP provides the organizational structure for coordinating several different projects which approach some aspect of Natural Language Processing. OpenNLP also defines a set of Java interfaces and implements some basic infrastructure for NLP compon Platforms: Windows, Mac, Linux

Talk Agent Project is creating a framework that allows developers to create inteligent agents which accept commands in natural language (English). Software agents are created by adding new ontologic knowledge and software components to the framework. Platforms: Windows, Mac, BSD, Linux

Grok is a library of natural language processing components, including support for parsing with categorial grammars and various preprocessing tasks such as part-of-speech tagging, sentence detection, and tokenization. Platforms: Windows, Mac, Linux

The zaubertrank is a programming system based on natural language, not parsed, but assembled from given statements. It aims to be easily accessible for non-programmers as well as useful for developers. The idea is to demystify program code. Platforms: Windows, Mac, Linux

Thinknowlogy is grammar-based software, designed to utilize the logic contained within grammar, in order to create intelligence through natural language, which is demonstrated by: * Programming in natural language; * Reasoning in natural language: drawing conclusions, making assumptions (with... Platforms: Windows, Mac, Linux

NLTK * the Natural Language Toolkit * is a suite of open source Python modules, data and documentation for research and development in natural language processing. This site is the home of NLTK development. . NLTK Home - the starting point for users including download instructions . Source -... Platforms: Mac

A natural language parser is a program that works out the grammatical structure of sentences, for instance, which groups of words go together (as "phrases") and which words are the subject or object of a verb. Probabilistic parsers use knowledge of language gained from hand-parsed sentences to... Platforms: Mac

Stanford CoreNLP provides a set of natural language analysis tools which can take raw English language text input and give the base forms of words, their parts of speech, whether they are names of companies, people, etc., normalize dates, times, and numeric quantities, and mark up the structure...
