Subject area-oriented method for recognizing new specialized vocabulary

The invention belongs to the fields of computer application and natural language processing and provides a subject area-oriented method for recognizing a new specialized vocabulary. The principle of the method is that: an initial document is subjected to the steps of text preprocessing, new word string counting, garbage word string filtration, result sorting and the like, and new words found from the document are output. Specialized terms of the subject area can be well found and results are sorted, and therefore the method overcomes the shortcomings of the conventional algorithm and is more favorable for mastering the development trend and the core value of the subject.
