Natural-language processing (NLP) can be used to answer a variety of questions about unstructured text data, as well as facilitating open-ended exploration.
It can be applied to datasets such as emails, online articles and comments, tweets or novels. Although the source is text, transformations are applied to convert this data to vectors, dictionaries and symbols which can be handled very effectively by q. Many operations such as searching, clustering, and keyword extraction can all be done using very simple data structures, such as feature vectors and bag-of-words representations.
The following requirements cover those needed to initialize running of the NLP library
A number of Python dependencies also exist for this library. These can be installed using Pip as outlined at KxSystems/nlp.
$ pip install -r requirements.txt
or via Conda
$ conda install --file requirements.txt
Besides those installed via the above code there is also a requirement that the English model be downloaded for Spacy:
$ python -m spacy download en
Tensorflow and Tensorflow_text are not a requirement to run this library, however, if installed, extra functionality is included.
The library is available from KxSystems/nlp.
Alternatively the library is available as a Docker image.
If you have Docker installed you can run:
