There are several libraries and frameworks available for building production-level NLP (natural language processing) applications. Here are some popular ones along with the programming languages they use:
Natural Language Toolkit (NLTK): NLTK is a popular NLP library for Python. It provides support for tasks such as tokenization, stemming, part-of-speech tagging, and parsing.
Stanford CoreNLP: Stanford CoreNLP is a suite of NLP tools written in Java. It provides support for tasks such as named entity recognition, sentiment analysis, and coreference resolution.
Apache OpenNLP: Apache OpenNLP is an NLP library for Java. It provides support for tasks such as tokenization, sentence segmentation, part-of-speech tagging, and named entity recognition.
spaCy: spaCy is a Python-based NLP library that provides support for tasks such as tokenization, part-of-speech tagging, named entity recognition, and dependency parsing. It is known for its speed and efficiency.
Gensim: Gensim is a Python library that provides support for tasks such as topic modeling and document similarity analysis.
Hugging Face Transformers: Hugging Face Transformers is a Python-based library that provides support for various NLP tasks, including natural language understanding and generation, text classification, and question-answering.
These libraries and frameworks are widely used in industry and research for building production-level NLP applications. The choice of library and programming language will depend on the specific requirements and goals of the project.
Stanford NLP and Apache OpenNLP are both widely used natural language processing (NLP) libraries, but there are some differences between them in terms of features, performance, and ease of use.

In summary, both Stanford NLP and Apache OpenNLP are powerful NLP libraries with their own strengths and weaknesses. The choice of library will depend on the specific requirements and goals of the project. If a wider range of features and high accuracy are important, Stanford NLP may be a better choice. If speed and efficiency are more important, Apache OpenNLP may be a better choice.
