Comparison of 6 top-level python NLP libraries!http://blog.itpub.net/31509949/viewspace-2212320/Natural language Processing (NLP) is becoming more and more popular today, especially in the context of deep learning and development. In the field of artificial intelligence, natural language processing (NLP) understands and extracts important information from text, and further

In addition to the keywords (keywords) and the built-in types and functions (builtins), Python provides more functionality through libraries (that is, modules).The Common libraries (modules) are as follows:1) Python Runtime service* The Copy:copy module provides a shallow copy and deep copy of the composite (compound)

Numpy and Scikit-learn are common third-party libraries for Python. The NumPy library can be used to store and handle large matrices, and to some extent make up for Python's lack of computational efficiency, precisely because the presence of numpy makes Python a great tool in the field of numerical computing; Sklearn is the famous machine learning library in
