5 Steps to Read Foreign-Language Research Papers Faster: A Workflow for Researchers That Cuts Your Reading Time in Half

"It takes me two or three hours to get through a single paper." "I keep reading on even when I haven't understood what a figure means." These are the frustrations our team hears most often when we talk with researchers and graduate students. From PhD candidates to corporate R&D scientists, the struggle to read papers written in a foreign language—Chinese, Japanese, English, or any language that isn't your own—seems to be shared across every career stage.

While building Languise, our team interviewed many researchers and graduate students. One comment from a third-year PhD student has stuck with us: "It's not that I can't read the foreign text—it's that I don't know where to start reading." That single remark is what led our team to focus on reading strategy. What these interviews made clear is that, for most people, "reading slowly" stems not from language ability but from the order in which they read and the tools they choose.

In this article, we've organized the efficient reading methods that researchers actually use into five steps, and we explain how AI tools can help at each one.

Why Does Reading a Foreign-Language Paper Take So Long?

Researchers are estimated to spend about 23% of their total working time reading scientific papers (PLOS ONE, 2017). That works out to roughly 9–10 hours a week. What's more, between 1993 and 2005 the number of papers an individual researcher read per year rose from 188 to 280, while the total time spent reading barely increased. In other words, the time available for each paper keeps shrinking.

Looking at these numbers, our team was reminded once again that what researchers need isn't "more time to read," but "a reading framework that lets them understand more in the same amount of time."

The main reasons reading a foreign-language paper takes so long boil down to three habits:

• Trying to read straight through from start to finish
• Spending too much effort interpreting figures and tables
• Stalling on technical terms

5 Steps to Read Foreign-Language Papers Efficiently

STEP 1: Start with the Abstract and the Figures (the first 10 minutes)

Nearly all experienced researchers practice one strategy: not reading from the beginning. One study found that 98.6% of science and health researchers read the abstract first to judge whether the paper is worth reading in full (PLOS ONE, 2024).

Here's the concrete procedure:

1. Read the abstract to grasp the paper's main claim (2 min)
2. Skim through all the figures, tables, and graphs (3 min): read at least the captions
3. Read the final paragraph of the Conclusion or Discussion (2 min): check what the authors are concluding
4. Decide whether the paper is worth reading closely (3 min): if relevance is low, stop here

By advancing only the papers you judge "worth reading" to the next step, you can screen a large volume of papers in a short time.

STEP 2: Understand the Structure Before Diving into the Body

Papers in the sciences follow the IMRAD structure, and each section has a fixed role. Once you understand this structure, the key to efficiency is changing the order in which you read depending on your goal.

"I just want the conclusion of this study" → Abstract + Conclusion. "I want to apply the method to my own research" → focus on Methods. Adjust your reading order and depth to match your goal.

STEP 3: Understand the Figures Before You Translate

One question our team hears often is: "I worked hard to translate the body text, but I still couldn't understand the figures." A paper's conclusions are condensed into its figures and tables—if you can read them, your comprehension of the body text improves dramatically. Conversely, if you leave the figures for later, you'll keep reading without grasping "what point is this trying to make."

There are three keys to reading figures and tables efficiently:

• Read the caption first to understand what the figure or table is showing
• Understand what the axes mean before reading the numbers
• Check the error bars and significance markers

If you use an AI tool, choose one that translates while preserving the PDF layout. With tools that misalign figure captions or axis labels, you can't tell which translation corresponds to which figure. Languise keeps the original layout intact even for two-column papers or those containing figures and tables, so you can view the figure and its translation side by side (if other tools offer the same capability, the same approach applies).

STEP 4: Make "Look It Up Later" a Hard Rule for Unfamiliar Terms

The habit that slows down reading a foreign-language paper the most is stopping to look up every unfamiliar word as it appears. Do this and you break the flow of the text, making it harder to grasp the big picture.

What our team recommends is using an "in-paper AI question" feature. The workflow is to read through the paper once, then ask the AI about the parts you didn't fully understand.

• "Please explain the role of p38 MAPK in Section 3 in plain terms."
• "What do the error bars in Figure 3 represent?"
• "What prior research does this study's methodology build on?"

When you have an environment where you can ask an AI about a paper's content after translating it, the effort of consulting dictionaries or searching for related articles drops dramatically. That said, when you ask an AI about a paper's content, always confirm whether the AI is answering "based on having actually read the PDF of that paper."

STEP 5: Lock In What You've Read Through Output

The final step to reading papers efficiently is not letting "read and done" be the end of it. Among the researchers our team interviewed, those who read with the highest efficiency were, without exception, producing some kind of output from what they read.

A few simple methods:

• Write down three points in your own words: "What did this study reveal?" "What method did it use?" "How does it relate to my own research?"
• Record passages you might use in your own paper or report, along with the figure or table number
• Leave critical notes—"Is this assumption valid?" "Isn't the sample size too small?"

For example, one pharmaceutical R&D researcher our team interviewed kept up this format for two months and found that reading follow-up papers from the same author group took less than half the time it used to. When you read the first paper carefully and leave notes, reading the next one becomes simply a matter of "reading by comparison." Build this output habit, and your comprehension speed rises every time you read the next paper on the same topic.

The "Speed × Comprehension" Matrix: Criteria for Choosing a Tool

When it comes to reading foreign-language papers more efficiently, the choice of tool is a factor you can't ignore. The comparison below is based on the priorities our team set while developing Languise, and we've organized it as a general-purpose set of criteria you can use to evaluate tools other than Languise as well. Use it as a reference for picking the tool that fits your needs.

Depending on the use case, a general-purpose translation tool is sometimes the best fit. However, for two-column science papers, papers heavy with equations and figures, or any case where you read a single paper in depth, we recommend using a tool with features purpose-built for reading research papers.

Conclusion: Combining Reading Strategy and Tools Changes How You Read Papers

Reading foreign-language papers efficiently doesn't require better language skills alone. By combining a reading-order strategy (nonlinear reading) with the right tools, many researchers have substantially shortened the time they spend reading papers.

To recap the five steps from this article:

1. Read the abstract, figures, and conclusion first, and decide whether to read closely before anything else
2. Understand the IMRAD structure, then change your reading order according to your goal
3. Understand the figures before the body text, then move into close reading
4. Make it a firm rule to ask an AI about unfamiliar terms later
5. Lock in your understanding with a three-line summary as output

For researchers who "have to read more than ten papers a week," a workflow that translates while preserving the PDF layout and combines side-by-side source display with an AI question feature is especially effective. One trend our team is observing is that, as AI tools advance, the difference in reading efficiency is driven less by "translation accuracy" and more by the literacy of "in what order, and how, you read."

[Supplement: For Those Reading Patents and Technical Documents]

Our team's audience includes not only researchers but also patent attorneys, IP professionals, and R&D staff in pharmaceuticals, chemicals, and manufacturing. For patent specifications and technical reports, the usual reading order isn't IMRAD but "claims → specification → drawings." And when screening a large volume of competitors' patents, an efficient approach is to rapidly translate only the abstract-equivalent "summary" to judge relevance, then read closely only the ones that matter. The five steps in this article focus on academic papers, but the thinking behind each one can be applied to patents and technical documents as well.
