Introduction to Neural Translation

Neural translation is the most advanced form of machine translation, using deep learning technology and artificial intelligence to generate precise and smooth translations of texts. This article aims to briefly introduce neural translation, discuss its history and provide basic information about its functioning. In recent years, neural translation has gained popularity and become a key element of modern intercultural communication.

The history of neural translation dates back to the 1950s. In the 1960s, scientists began experimenting with the first machine translation models. At that time, however, translations were far from perfect and often generated texts that were difficult to understand. As technology progressed, researchers began to explore different machine translation methods, such as rule-based and statistical translation.

In 2014, a breakthrough occurred when Google researchers presented the first model of translation based on neural networks. The neural translation is based on deep learning technology, which allows computers to learn from big data analysis. Neural networks learn to recognize patterns and relationships between different text elements, allowing them to generate high-quality translations that are similar to human translations.

The functioning of neural translation can be compared to the work of the human brain. Neural networks comprise multiple layers, each analysing different aspects of the text. For example, one layer can analyze syntax, another can analyze semantics, and another can analyze context. Thanks to this structure, neural networks can understand the complexity of language better than other machine translation methods and generate more smooth and precise translations.

Neural translation has many advantages that make it increasingly popular in various fields. First, it allows you to translate texts faster than traditional methods, especially when time is key in business or scientific environments. In addition, neural translation can generate high-quality translations, enabling it to compete successfully with human translations. Finally, neural translation can continually learn and refine its skills, which means that its translation quality will improve as it analyzes more texts.

Neural translation is a revolutionary approach to machine translation that is fundamentally rooted in the structure and functioning of the human brain. Artificial neural networks, which are the foundation of this technology, mimic the operation of the brain by having multiple layers of interconnected nodes. Each layer is responsible for processing specific aspects of information, such as syntax, vocabulary, and grammar.

Using training data, these networks learn to recognize patterns and relationships between words, progressively increasing their precision with each layer. This results in highly accurate translations that are almost indistinguishable from human translations. Neural translation is a powerful tool that has revolutionized the translation industry, enabling businesses to communicate with their customers in more languages and with greater ease.

Deep learning

Deep learning is a game-changer in the field of machine translation.

The beauty of deep learning lies in its ability to learn from large amounts of data, allowing it to identify patterns and relationships between words that would be impossible for a human translator to detect. It can then use this knowledge to produce highly accurate translations, even for complex sentences with multiple clauses and idiomatic expressions.

Another advantage of deep learning is its ability to adapt to different data types. Whether the input is a text, image, or sound, deep learning algorithms can be trained to recognize and interpret it with incredible accuracy. This makes it a versatile tool for various applications, from language translation to image recognition and speech synthesis.

Deep learning is a powerful technique for improving machine translation accuracy and efficiency. Its ability to learn from large amounts of data and discover hierarchical patterns in that data make it a valuable tool for businesses looking to communicate with customers in multiple languages. As technology evolves, we can expect even more impressive results from deep learning in machine translation.

Translation of sequence-to-sequence

The basic algorithm used in neural translation is the sequence-to-sequence (seq2seq) model. This model consists of two main components: an encoder and a decoder. The encoder analyzes and converts the input sentence into a numerical representation, which is then passed to the decoder. The decoder converts the numeric representation into an output sentence in the target language. This process uses techniques such as recursive neural networks (RNNs) or attention mechanisms that allow context and relationships between words in translation to be considered.

What is the quality of neural translation?

The quality of neural translation can be defined as the degree to which machine translation reflects the meaning of the source text in the target text while maintaining grammatical, lexical, stylistic and semantic correctness. The quality of neural translation depends on many factors, such as the precision of the neural model, understanding the context or the ability to convey language nuances.

Metrics and assessments of the quality of neural translation

There are many metrics for assessing the quality of neural translation; none are perfect. Here are some of the most popular.

• BLEU (Bilingual Evaluation Understudy) – a metric comparing machine translation with a reference translation (or several reference translations) made by a human translator. BLEU assesses the similarity between the translations in terms of the words, phrases and grammar used.

• TER (Translation Edit Rate) – a metric based on the number of edits (adding, deleting, replacing words) necessary to bring machine translation to the level of reference translation.

• METEOR (Metric for Evaluation of Translation with Explicit ORdering) – a metric that considers both precision, i.e. the ratio of correct words in machine translation to all words, and completeness, i.e. the ratio of correct words in machine translation to all words in the source text.

Neural translation quality assessment tools

In addition to the quality assessment metrics, many tools allow you to automate the process of evaluating machine translations. Here are some of them.

OpenKiwi – a machine learning tool that allows you to assess the quality of machine translation at the level of words or phrases. OpenKiwi allows you to train your own quality assessment models, useful in specialized fields or languages.

Neural translation quality assessment process

Neural translation quality assessment is a process that consists of several stages. Here are the most important of them.

Reference translation – to assess the quality of a machine translation, a reference translation is needed, i.e. a translation made by a professional human translator. The reference translation serves as a benchmark for quality assessment metrics and tools.

Automatic evaluation – using selected metrics and tools, machine translation is evaluated in precision, fullness, grammar or style. As a result of the automatic evaluation, numerical values are obtained that reflect the quality of the machine translation.

Expert assessment – because no metric or tool is perfect, expert assessment, i.e. the assessment of machine translation by professional translators or linguists, is essential. Experts evaluate machine translation in terms of understanding the context and transmitting language nuances or specialist terminology.

Analysis of the results – based on the automatic and expert evaluation results, it is possible to draw conclusions about the quality of neural translation, identify areas for improvement and adapt the neural model to specific needs.

Challenges in assessing the quality of neural translation

Neural translation quality assessment is a complicated process, and the performance of metrics or tools does not always reflect the actual quality of the translation. Here are some challenges you may encounter when evaluating the quality of neural translation.

• The subjectivity of assessment – the quality of the translation is often subjective and different translators may have different opinions about what is correct or better. Therefore, the expert evaluation must be based on common criteria and guidelines.

• The diversity of languages – it may be more difficult to assess the quality of neural translation for less widely used or complex grammatical structures. In such cases, there are fewer reference translations, which makes it difficult to assess the quality.

• The context and nuances – quality assessment metrics often cannot fully consider the context or language nuances. Therefore, expert evaluation is necessary to assess whether the neural translation is adequate and understandable.

• The specialized terminology – assessing the quality of neural translation can be particularly difficult in the case of specialized texts, where terminology and expressions are unique to a given field. In such cases, experts in the field may be needed to evaluate the machine translation.

Improving the quality of neural translators

Evaluating the quality of neural translation is not just a means of diagnosis but also a way of enhancing the performance of neural models. Here are some strategies to improve the quality of neural translation.

Fine-tuning the model - adapting the neural model to specific needs by further training it on source and reference texts in a given field or language.

Collaborating with experts - consulting with translators or linguists can help understand problems related to context, nuances, or specialist terminology and implement appropriate adjustments in the neural model.

Integrating with other technologies - combining neural translation with other technologies, such as artificial intelligence, natural language processing (NLP), or unsupervised learning, can lead to better machine translation results.

In summary

Assessing the quality of neural translation is an integral part of the machine translation process. By utilizing appropriate metrics, tools, and evaluation processes, it is possible to diagnose the quality of the neural translation and improve the neural models for even better results. Challenges related to quality assessment, such as subjectivity, language diversity, context, and specialist terminology, require both automatic and expert evaluation.
