Applications of Language Studies defines plagiarism as:
"The unattributed appropriation of intellectual content—including concepts, textual expressions, structural frameworks, or research findings—through verbatim reproduction, inadequate paraphrasing, or misrepresentation of provenance."
All following constitute academic misconduct:
Presenting others' work as original scholarship
Reproducing verbiage or ideas without attribution
Falsifying source documentation
Preserving source syntax through superficial lexical substitution
Deriving >30% of content from single sources (even with attribution)
Unauthorized use of visual elements (figures/images/graphs) without:
Copyright holder permission
Contextual citation
ALS employs industry-standard plagiarism detection software (iThenticate) to screen submissions. Manuscripts undergo similarity analysis pre-peer-review with these thresholds:
| Similarity Index | Action |
|---|---|
| < 20 % | Proceed to peer review |
| 15-30% | Mandatory revision with source remediation |
| > 30% | Immediate rejection |
Plagiarism discovered after publication triggers:
COPE-guided investigation
Retraction for severe violations (>25% unattributed content)
Correction for localized infractions
Attribute all non-original content using APA/MLA conventions
Secure written permissions for copyrighted materials
Distinguish verbatim text via:
Quotation marks (short passages)
Block indentation (>40 words)
Deposit linguistic data/corpora in disciplinary repositories (e.g., TalkBank, CLARIN)
Disclose AI-assisted writing in Methods section (excluding grammar tools)
Special Consideration: Linguistic researchers must properly attribute
Unpublished corpus data
Fieldwork informant contributions
Translated/adapted materials
