It can complete basic tasks such as word segmentation, part-of-speech annotation, naming entity recognition, etc. The usage process includes installing pipinstallnltk, downloading corpus such as punkt and wordnet, importing modules and calling functions to process text, such as word_tokenize to implement word segmentation, pos_tag for part-of-speech annotation; it also supports stop word filtering, word form restoration and other functions, but attention should be paid to problems such as text preprocessing and weak Chinese support. It is recommended to use spaCy or transformers for large-scale processing.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
