When we talk about translation quality, we do not simply mean translating every word correctly and following punctuation rules. One of the main goals of a translated text is to convey the meaning of the original material as accurately as possible. It is important to understand that a word-for-word or literal translation does not always achieve this. The way terms, phrases, and entire sentences are translated directly affects how readers perceive the text. To ensure that the translation faithfully conveys everything intended in the source text, a translation quality review is necessary. It involves a structured set of methods and procedures, which we will discuss in this article.
Why Translation Quality Cannot Be Assessed “At a Glance”
Many people believe that determining whether a translation is good simply requires reading it and assessing it “at a glance.” However, this is a serious mistake because such an approach can reveal only obvious shortcomings and does not show how accurately the author’s intended meaning has been conveyed. The same word can have completely different meanings depending on where and how it is used, so context must always be taken into account.
It is also not always possible to determine the writing style on a first read; often, only the general meaning is immediately clear. Yet style is highly important because it affects how the target audience perceives the text. To account for all of these factors, a systematic approach is needed when assessing translation quality. The text must be evaluated against multiple criteria, which together determine the overall quality of the translated material.
What Is LQA and What Does the Review Include?
LQA is a methodology that uses a range of techniques to assess a translated text against several evaluation criteria. These include:
- accuracy. The first step is to make sure that the translation preserves the meaning conveyed in the source text. This does not mean checking only the translation of individual words. Phrases and complete sentences must also be reviewed, since together they shape the overall meaning of the text. Particular attention should be paid to words whose meaning may vary depending on the context in which they are used in the target language. It is also essential to ensure coherence between sentences;
- grammar, style, and terminology. The second stage involves reviewing the grammar, writing style, and terminology used in the translation. The text should be checked for spelling and punctuation errors, as well as for correct syntax and sentence structure. The writing style is equally important and should match that of the source material - for example, it may be formal and reserved or more casual and friendly, with a more informal way of addressing the target audience. Terminology should also be reviewed. What matters here is not a literal translation of each term, but whether it conveys the exact meaning intended in the source text;
- compliance with tone of voice and local conventions. The third stage focuses on ensuring that the translation is consistent with the brand’s tone of voice and the linguistic conventions of a specific target market. This includes the localization of currencies, units of measurement, date formats, and proper names.
Only a comprehensive approach can ensure a high-quality translation that preserves both the meaning and the writing style of the original text.
How Translation Errors Are Evaluated
Once the translation is complete, it needs to be reviewed. During this process, errors may be identified, and it is useful to classify them according to their severity. The relevant text fragment is recorded, the type of error is specified, and the correction is documented. In other words, both the “before correction” and “after correction” versions are provided. Once all identified errors have been addressed, the text is reviewed again to determine how much it has improved and whether it now meets all requirements for translation accuracy, style, and context. Consistently classifying errors can also reveal recurring issues. This makes it easier to avoid them in future translations.
Error Categories and Severity Levels
To assess the quality of a translated text, it is reviewed for translation errors, which are classified into three categories:
- critical. These are errors that can significantly alter the meaning of the content. As a result, the target audience may interpret the material very differently from what was originally intended. This can lead to serious consequences, particularly in areas such as legal or medical content or technical instructions;
- major. These errors reduce the overall quality of the translation but do not fundamentally change the meaning of the text. Even so, they must still be corrected;
- minor. These include punctuation and syntax issues, as well as wording that may sound unnatural to native speakers because the text has not been properly adapted.
Each error can be assigned a score on a three-point scale, such as 3, 2, or 1. The higher the score, the lower the translation quality.
Quality Metrics Based on MQM
MQM is a framework used to evaluate translation quality across multiple criteria. These may include accuracy at the word, phrase, and sentence levels, the overall meaning conveyed by the text, its style, and how it is likely to be perceived by the target audience. Grammar can also be assessed separately, including syntax, punctuation, spelling, and the correct use of grammatical structures.
By evaluating each criterion individually, it becomes possible to form an overall picture of the quality of the translated material. Error classification also helps determine how well the translation meets established quality standards. Once the text has been assessed, the errors identified under each criterion should be corrected to achieve a high standard of translation quality. This is precisely how translation quality metrics support a comprehensive approach to text review, helping ensure that the translation fully reflects the source material in both meaning and style.
Quality Control Tools: Glossaries, Translation Memory, and QA Checkers
To ensure that a translation matches the source text as closely as possible, specialists use a range of translation quality assurance tools. These include:
- glossaries. These function as reference resources containing terminology and guidance on how specific terms should be used. Each term can also include an explanation of the context in which it should be used. This is particularly useful in specialized fields such as medicine, law, and technical documentation, including manuals and instructions;
- translation memory. This is a database that stores previously translated segments for future reuse. If the same segment appears again, an existing translation is available. This helps prevent the same content from being translated differently or interpreted inconsistently across different contexts;
- QA checkers. These tools make it possible to identify errors quickly, including issues that can be difficult to detect during a manual review.
Tools like these are commonly used in professional translation services to help maintain a high standard of translation quality.
How Clients Can Check a Translation Without Knowing the Language
Of course, not every client knows the language into which their content needs to be translated. However, the translation still needs to be reviewed. In this case, the best option is to work with specialists who can assess it using a range of methods and tools. Only a comprehensive translation review can provide an objective assessment of its quality, including grammatical correctness, accuracy, intended meaning, and writing style. The reviewer should also be provided with all requirements for the text, as well as the glossary used during the translation process.
