The pressure to publish in multiple languages is intensifying across academia. International journals increasingly require translated abstracts. Researchers in non-English-speaking countries need to make their work accessible to local audiences as well as global ones. Institutions distribute translated summaries of key research to policymakers, press, and partner organizations.
This guide provides a specialized workflow for translating academic papers, focusing on preserving complex equations, figure labels, and charts while ensuring technical terminology remains accurate across disciplines.
Academic papers present a unique translation challenge: they mix multiple content types on every page. Prose arguments sit alongside mathematical notation, chemical formulas, statistical tables, figures with embedded labels, and charts with translated axis text.
Traditional text-extraction tools ignore everything that isn’t plain text. They extract the prose, translate it, and miss every figure, equation, table, and embedded label. The result requires a designer to reassemble the document — at significant cost.
Translayer works with the page as a whole image, translating all visible text including embedded chart labels and figure captions, while preserving every mathematical and chemical expression exactly as rendered.
What Translates vs. What Stays
Understanding which elements translate and which stay unchanged is important for academic content:
Translates:
- Body text (prose, arguments, methodology descriptions)
- Abstract and conclusion sections
- Section headings and subheadings
- Figure captions and table titles
- Chart axis labels and legend text
- Table headers and cell text (if the cells contain prose)
- Footnotes and endnotes
- In-text citation context (surrounding text; citation markers stay unchanged)
Does not translate (preserved as-is):
- Mathematical equations and formulas
- Chemical structures and notations
- Numeric values in tables (these are numbers, not words)
- Citation markers ([1], Smith et al., etc.)
- Statistical notation (p-values, confidence intervals as numeric expressions)
- Acronyms established as terminology
Discipline-Specific Vocabulary
Every academic field has specialized vocabulary. Some terms translate directly; others are either left in English (the international convention) or have specific translations established by the target language’s academic community.
Medicine and biology: Medical Latin terms are often retained across languages (Latin being the historical language of science). However, clinical procedure names, drug names, and diagnostic terms have regulated translations in many countries.
Mathematics and physics: Most notation is universal. The prose surrounding it uses precise disciplinary vocabulary where the “correct” translation in the target language may differ from the literal translation.
Social sciences: The most translation-sensitive field. Concepts like “agency,” “habitus,” “praxis” carry specific theoretical meanings in particular academic traditions. A literal translation may miss the theoretical reference entirely.
Computer science: Many English terms are used internationally without translation (algorithm, software, interface, API). Forcing translations can produce awkward results in languages where the English terms are standard.
Build your terminology prompt before translating. Consult a colleague who works in the target language academic community to validate key term choices.
Handling Equations
Mathematical equations appear in two forms in academic papers:
Inline equations — Short expressions within running text, rendered as part of the text flow. Translayer identifies these and preserves them as visual elements, translating only the surrounding text.
Display equations — Numbered, centered equations on their own line or in equation boxes. These are also preserved as visual elements. The equation number (if present on the side) is treated as a non-translatable identifier.
What Translayer translates in equation contexts:
- The variable definitions that appear after equations (“where x represents the initial concentration”)
- Equation labels in captions or the surrounding text
- Units of measurement that appear in text (but not within equations)
Charts and Figures
Academic charts typically contain:
- Chart title — usually a caption below the figure; translated
- Axis labels — embedded text on x and y axes; translated
- Legend entries — series labels within the chart; translated
- Data labels — values displayed on data points or bars; usually numbers, preserved
- Annotations — text boxes or arrows pointing to specific data features; translated
For figures (diagrams, schematics, microscopy images, etc.):
- Figure caption — translated
- Labels — text pointing to elements of the figure; translated
- Scale bars — numeric values + units; units may translate, values preserved
Resolution matters for charts: If your source PDF renders charts at low resolution (under 150 DPI), small axis label text may be blurry. For papers with small-text-heavy figures, extract at 600 DPI.
Reference Lists
Reference lists present a specific decision: do you translate reference titles?
Standard academic practice:
- Authors’ names — NOT translated (unless you are translating to a language using a different script, in which case romanization conventions apply)
- Journal names — NOT translated (standard abbreviations are international)
- Book titles in the references — convention varies:
- Some traditions: translate in brackets “[Title translated]”
- Others: leave original title, add “[in Language]” notation
- Most common for general audiences: leave untranslated
Specify your preference in the custom prompt if you have a specific convention to follow.
The Abstract: Your Most Important Page
The abstract is the most-read page of any academic paper. It is the page that appears in search engines, databases, and journal listings. Translated abstracts dramatically expand discoverability.
For abstracts, after AI translation:
- Have a domain expert (not just a language expert) review the translated abstract
- Verify that all key technical claims are translated accurately
- Check that the contribution statement is clear in the target language
- Ensure statistical results are reported correctly
A 200-word abstract review by a bilingual domain expert takes 15–30 minutes and is the highest-value review investment you can make.
Use Cases by Academic Role
Individual researcher: Translating papers for submission to regional journals, conference proceedings in other languages, or institutional repositories requiring local language versions.
Journal editor: Preparing translated abstracts or full-text translations for international editions or multilingual proceedings volumes.
Research institution: Translating working papers, reports, and research summaries for policy audiences, partner institutions, or public communication.
Graduate student: Translating thesis chapters for advisor review in different language contexts, or translating source material papers from other languages.
Summary
In summary, translating academic papers requires a system that can handle the complex interplay of prose, equations, and charts. By using Translayer’s image-based translation and following discipline-specific terminology guidelines, researchers can efficiently disseminate their work to a global audience without losing technical precision.
Frequently Asked Questions
How does Translayer handle mathematical equations in academic papers?
Translayer treats equations as visual elements rather than text. It identifies and preserves them exactly as they are rendered in the original, translating only the surrounding prose and labels.
Can AI translate labels within charts and figures?
Yes. Unlike traditional text-extraction tools, Translayer works with the page as an image, allowing it to detect and translate embedded axis labels, legend entries, and figure annotations.
What is the best way to ensure terminology accuracy in a specific scientific field?
We recommend using a discipline-specific terminology prompt. List your key terms and their preferred translations before processing to ensure consistency with the target language's academic community.
Should I translate the reference list in my paper?
Standard academic practice is to leave author names and journal titles untranslated. For book titles, you can choose to leave them as-is or add a translation in brackets, which can be specified in your custom prompt.
