HowNet Literature Search Notes
Preface
Sophomore took a course in literature retrieval. I was interested and took a note. Now refer to it. You can learn from it when you write a paper in the future.
But it was a little superficial. At that time, my feeling about papers was boring. At that time, I used Baidu, Jianshu, and Zhihu to collect information. I didn't take it seriously because I didn't do scientific research.
But now it is found that HowNet is still necessary for reference. Especially after the graduation project to write thesis.
In fact, I have read now that CNKI document retrieval is more accurately information gathering ability.

to sum up
I think the core of document retrieval is the ability to collect information.
It has been there since ancient times. It's just that in ancient times it is the library of books, and in modern times it is the electronic library of books (CNKI);
Information collection ability (collection channels): external data (websites, newspapers, TV) and internal data (personal connections, eyeliner); the stronger the information collection ability, the more data obtained and the higher the credibility;
Information analysis ability (domain knowledge): general knowledge (mathematics), professional knowledge (economics, geography, computer science); the stronger the information analysis ability, the better the ability to understand and process information, and the ability to distinguish credibility and ability In conclusion;
Information application ability (thinking): combine vertical and horizontal. Using information gathering ability and information analysis ability to face complex problems can find solutions.
