You can find related papers and academic articles by entering keywords or paper topics for search. These search engines will provide abstracts, citations and full-text links (if any).

2. Academic database: ScienceDirect, IEEE Xplore, ACM digital library and other academic databases are used. These databases collect a large number of academic journals, conference papers and dissertations. You can search according to the title of the paper, the author's name or keywords, and get the detailed information of the relevant paper and the full-text download link (if you have permission).

3. Academic social platforms: Use academic social platforms, such as ResearchGate and Academia.edu, which provide personal homepages of researchers and their papers. You can get their latest papers by paying attention to interested researchers.

4. Library: Go to the school or local library and use the academic resources and databases provided by the library for retrieval. Some university libraries or national libraries also provide online academic resources and databases.

Please note that some papers may need to be paid to get the full text. You can try to contact the author or look it up in the academic database of paid subscription. In addition, in order to ensure the academic credibility of the paper you find, you should check the citation of the article, the qualification of the author and the reputation of the research institution.
