Preface: analyze key words

How to extract the corresponding keywords from a text?

I have thought about using machine learning method for lexical analysis before, but the accuracy of the test in the project is not enough. At this time, there is the idea of HanLP- Chinese language processing package to extract keywords.

Download: .jar .properties data and other files

Here is the official website download address HanLP download, 1.3.3 packet download

Configure the environment in intellij and run the first demo

Configure the jar package in the project to add dependencies.

File- > Project Structure- > Modules- > Dependencies- > + Jars

Transfer the properties file to the src root directory, and modify root to your own dataset path

Failed to load the corresponding table of character types: D:/BaiduYunDownload/data-for-1.3.3/data/dictionary/other/CharType.dat.yes

Solution: check to see if the file is available under the error page, and if not, download one online. For example, here, because I only use part of its functions, I no longer download it for convenience. Here I directly change the file name of a file-successfully run it!
