How do I split and match keywords within an article? For example, the following articles:

I want to write down some of the words in the article as a keyword to use when the user publishes the article. Are there any algorithms/ideas that can achieve this requirement? Or can you only read and summarize/extract the keywords manually?
------Solution--------------------
1 A keyword table (can be added)
2. Calculate keyword Frequency
Don't do your own participle, hehe
Edit (the person/position referred to here) is still needed
------Solution--------------------
The 1 system Keyword table automatically matches the replacement keyword.
2 Specify keywords when user input

2, the processing of the document when the landlord posted sample text
3, the code is now written, about the algorithm problem please correct me
