Three rulebooks, not one
University: degree rules, similarity thresholds, whether a paper-collection thesis is allowed, and how published chapters must be labeled.
Venue: whether the thesis counts as prior publication, whether preprints/theses are exempt, and what to disclose. Copyright: whether figures and text may enter a compilation thesis.
Usually safe patterns
When a thesis chapter maps to a published paper, label the source, contributions, and edits at the chapter head; write a unifying introduction and conclusion rather than pasting five abstracts.
If the thesis came first: treat it as existing text, disclose it, and make sure the journal/conference submission adds enough new material—or follows the venue’s overlap policy.
- Published → thesis: usually fine if labeled per school rules
- Thesis → submission: disclose and check prior-publication policy
- Coauthored papers in a thesis: state your contribution clearly
Similarity and self-plagiarism
University checkers often index your published papers and preprints; high overlap with yourself may flag—follow graduate-school guidance on exclusions and citation labels.
For journals, the issue is usually undeclared duplicate publication, not “sounding like you.” Disclosure plus new contribution matters more than gaming a percentage.
FAQ
- Include a paper still under review in the thesis?
- Often as an “under review” chapter if the school allows—but keep dual-submission and anonymity rules intact for the venue.
- English conference paper vs Chinese thesis?
- Different language does not make them unrelated work. Label sources in the thesis; when submitting to a Chinese journal, explain the conference relationship.
