1. INTRODUCTION
The translation landscape has undergone a dramatic transformation due to the emergence of
powerful transformer-based models like Bidirectional Encoder Representations from
Transformers (BERT), Generative Pre-trained Transformer (GPT), and Text-to-Text Transfer
Transformer (T5). These models have revolutionized Natural Language Processing (NLP) tasks,
particularly machine translation, by leveraging the “attention” mechanism. Unlike traditional
sequential models, transformers excel at understanding long-range dependencies within
sentences, enabling them to capture complex grammatical structures and nuances crucial for
accurate translation, (Vaswani et al., 2017). Pre-training on massive datasets as these models are
pre-trained on vast amounts of text data, allowing them to learn general language representations
that can be fine-tuned for specific translation tasks (Devlin et al., 2019; Radford et al., 2019;
Raffel et al., 2020). And, achieving state-of-the-art performance. Transformer models have
consistently outperformed previous approaches in benchmark translation tasks, demonstrating

16
significant improvements in fluency, grammatical correctness, and overall quality, (Ott et al.,
2018; Sockeye Team, 2019).
In today’s interconnected world, language barriers often pose significant challenges in
communication, trade, and understanding across diverse cultures and languages. With the swift
progression of Artificial Intelligence (AI) and NLP techniques, there has been a revolutionary
transformation in translation technology. This transformation has been marked by the advent of
sophisticated transformer-based models: BERT, GPT, and T5. These models have significantly
enhanced the accuracy and efficiency of Machine Translation (MT), leading to a paradigm shift
in the way languages are translated and understood. Zaki, (24) further explains that MT is a
branch of Computational Linguistics (CL) or Natural Language Processing (NLP) that studies the
use of software to convert text or speech across natural languages. It is a web-based software that
converts text into a variety of target languages throughout the world.
The objective of this comparative study is to delve into the intricacies of these cutting-edge
transformer models and analyse their respective strengths and limitations in the context of
translation tasks. BERT, GPT, and T5 represent the pinnacle of NLP, each offering unique
approaches to language representation and understanding. By comparing these models
comprehensively, the study aims at providing valuable insights into their performance, enabling a
deeper understanding of their applications in real-world scenarios.
The study begins by exploring the historical evolution of MT and the challenges faced by
traditional methods. It provides a backdrop to the emergence of transformer-based models,
elucidating the underlying principles that differentiate them from earlier approaches.
Understanding the context is essential to appreciate the significance of these advancements in
Transformer Models provides a detailed explanation of the BERT, GPT, and T5 transformer
architectures. It delves into their core components, including attention mechanisms, encoder-
decoder structures, and pre-training techniques. A comparative analysis of these components sets
the stage for evaluating their impact on translation tasks. BERT in Translation is a bidirectional
model that excels in capturing contextual information from both left and right context words.
This study explores how BERT has been utilised in translation tasks, highlighting its strengths
and limitations. Some researches demonstrate its effectiveness in handling specific language pairs
and nuanced translations.
GPT in Translation is a generative model that focuses on generating coherent and contextually
relevant translations. The study examines into the applications of GPT in MT, emphasising its
ability to produce fluent and contextually appropriate translations. Real-world use cases to
showcase the power of GPT in handling complex sentence structures and idiomatic expressions.
T5 in Translation is a text-to-text transfer model that represents a versatile approach to
translation, treating all tasks as text generation problems. It explores how T5 has been leveraged
for translation tasks, emphasising its flexibility in handling diverse languages and translation
domains. Comparative studies between T5 and traditional translation models highlight its
superiority in various scenarios.
The comprehensive comparative study aims at guiding researchers, translators, and enthusiasts
with a nuanced understanding of how BERT, GPT, and T5 revolutionise translation technology.
Through critical analysis and real-world examples, this study illuminates the transformative
potential of these models, paving the way for a more connected and linguistically inclusive global
community.

Machine Translation (MT) has come a long way since its inception, with significant
advancements driven by various techniques and models. One of the pivotal milestones in the
evolution of MT is the development of transformer models, which have greatly enhanced
translation quality and efficiency. A preliminary assessment is presented on how MT has
evolved, leading up to the transformative role of transformer models. MT research began in the
mid-20th century with rule-based approaches. Early systems depend on linguistic rules and
dictionaries to translate text from one language to another. However, these systems were limited
by the complexity of language and often produced translations of poor quality.
In the 1990s and 2000s, Statistical Machine Translation (SMT) emerged as a dominant paradigm.
SMT systems used statistical models to learn patterns from large bilingual corpora. These
models, such as phrase-based models, improved translation quality significantly by capturing
statistical relationships between phrases in different languages. Around 2014, Neural Networks
(NNs) revolutionised MT with the introduction of Neural Machine Translation (NMT) models.
Unlike rule-based and statistical methods, NMT used deep learning techniques to directly learn
the mapping from one language to another. Recurrent Neural Networks (RNNs) and Long Short-
Term Memory (LSTM) networks were initially employed for this purpose, providing better
translation quality compared to earlier methods.
The breakthrough came in 2017 with the introduction of the Transformer model, as described in
the paper “Attention is All You Need” by Vaswani et al., (2017). Unlike previous architectures,
transformers relied on self-attention mechanisms, allowing the model to weigh the importance of
different words in the input sentence when generating the translation, (D’Souza, 54). This
attention mechanism enabled transformers to capture long-range dependencies and improved the
quality of translations significantly. Some benefits of Transformer Models in Translation are:
- Transformers can process input sequences in parallel, making them much faster than
sequential models like RNNs. This parallelisation greatly enhanced the efficiency of
translation systems.
- They excel at capturing long-range dependencies in language, allowing them to generate
more contextually accurate translations, especially for complex sentences.
- They can be scaled up to handle large amounts of data, leading to the development of
massive pre-trained models (GPT and BERT), which have further improved translation
quality through transfer learning.
- They have been extended to handle multimodal translation tasks, where both text and
images are translated simultaneously. This capability is crucial for applications like
image captioning and multilingual visual recognition.
Since the introduction of transformers, research in MT has continued to advance. Techniques like
self-supervised learning, reinforcement learning, and iterative back-translation have been
employed to further enhance translation quality and address challenges related to low-resource
languages and domain adaptation. The evolution of MT from rule-based systems to statistical
methods and, finally, to transformer models has significantly improved translation quality and
efficiency. According to D’Souza, (52) transformers, with their ability to capture long-range
dependencies and process input data in parallel, have played a pivotal role in shaping the modern
landscape of MT. Ongoing research and advancements continue to refine translation systems,
making them more accurate, versatile, and applicable in various real-world scenarios.
Moreover, understanding the nuances of BERT, GPT, and T5 models is crucial in the context of
translation technology, as these models represent significant advancements in NLP and have

18
distinct characteristics that make them suitable for various translation tasks. Let us break down
the importance of understanding these models in the context of translation technology:
BERT:
- BERT is considered to comprehend the milieu of words in a sentence. It reads text
bidirectionally (putting into consideration both left and right context in all layers) and
captures the relationships between words.
- Understanding BERT’s contextual embeddings is essential for fine-tuning translation
models. Translators can benefit from these embeddings to handle complex sentence
structures and ambiguous phrases in different languages.
- BERT’s ability to grasp the semantic meaning of words and phrases aids in more
accurate translations, especially for languages with intricate nuances.
GPT:
- GPT models are generative and can produce coherent and contextually relevant text. This
characteristic is useful for generating translations fluently and naturally.
- It generates text autoregressively, meaning it predicts the next word based on the
preceding context. Understanding this sequential nature is vital for translators to create
fluent translations that maintain coherence and meaning.
- It’s creative text generation abilities can be harnessed to explore diverse ways of
expressing ideas and concepts in different languages, making translations more engaging
and culturally appropriate.
T5:
- T5 treats all NLP tasks, including translation, as text-to-text tasks. This unified
framework simplifies the translation process, as both source and target languages are
treated as text inputs, allowing for consistent handling of diverse language pairs.
- It’s ability to learn task-agnostic representations of text allows for efficient transfer
learning. Translators can leverage pre-trained T5 models to adapt to specific translation
tasks, benefiting from the model’s general language understanding capabilities.
- Translators can fine-tune T5 models for specific translation domains or styles, tailoring
the translation output to meet specific requirements, such as technical, literary, or
conversational translations.
Understanding the unique features and capabilities of BERT, GPT, and T5 models empowers
translators to choose the right model for specific translation tasks. This knowledge also enables
the fine-tuning and customisation of these models to improve the accuracy, fluency, and cultural
appropriateness of translations in diverse linguistic contexts. Keeping pace with advancements in
these NLP models is essential for the continuous improvement of translation technology,
ensuring high-quality translations that resonate with the target audience. For Zaki, (27) NLP “is
the ability of computers to understand human language. Natural language is human language and
computers can analyse, understand, alter and generate it”. This is further used for translation
purposes in MT as corpus, text or data.
Moreover, the performance of these models on translation tasks can vary based on the specific
dataset, training techniques, and evaluation metrics. Generally, T5, being specifically designed
for text generation tasks like translation, often outperforms BERT and GPT on translation-related
benchmarks. However, it’s essential to note that the field of NLP is rapidly evolving, and newer
models and techniques might have been developed. It is against this background that the
researcher finds it essential to explore the power of these transformer models in translation
technology.

19
The rationale behind the study is to evaluate and compare the transformer models in translation
technology.
The objectives of the study are to:
i. Identify the transformer models in terms of quality and effectiveness in translation
tasks,
ii. Evaluate their efficacy in translation technology,
iii. Compare the transformer models and their contribution in revolutionising
The justification of the study is their architecture, capabilities, and applications in the context of
translation technology. The study considers the returns of transformer models such as
instantaneous input sequence processing, handling language’s long-range dependencies, and
managing numerous translation tasks. It is through recognition of these transformer models’
exceptional structures that permits translators to select the best transformer model for particular
translation tasks and adjust them for better accuracy, fluency, and cultural relevance in translation
processes.
2. LITERATURE REVIEW: TRANSFORMER MODELS - A DEEP DIVE
The review offers an explanation of transformer architecture, focusing on the key components
such as attention mechanisms, encoder-decoder structure, and self-attention mechanisms. It
provides an in-depth analysis of BERT, GPT, and T5 models, exploring their unique features,
training methodologies, and underlying principles. BERT, GPT, and T5 models are Large
Language Models (LLMs) used for various NLP tasks. In the context of email spam detection,
LLMs have shown superior performance compared to traditional machine learning techniques
such as Naïve Bayes and Light GBM, especially in scenarios with limited training samples.
Spam-T5, a fine-tuned Flan-T5 model, outperforms other LLMs and baseline models in detecting
email spam, particularly when training samples are scarce, (Varginia, et al., 2021). In the field of
relation extraction for drug-protein interactions, BERT-based models and T5 models have been
explored. Larger BERT-based models have generally performed better, while the T5 text-to-text
approach shows promising results and has room for further research, (Jianmo et al., 2021). T5
models have also been investigated for generating sentence embeddings, with encoder-only
models outperforming BERT-based sentence embeddings on transfer tasks and Semantic Textual
Similarity (STS). Scaling up T5 to billions of parameters consistently improves downstream task
performance, (Xin, et al, 2021). In predicting drug-protein interactions, an ensemble model
combining fine-tuned BERT, sentence BERT, and T5 models achieved high performance, with
the best model achieving an F-1 score of 0.753, (Peng et al, 2019). With the above literatures,
these models are proved to be efficient and provide promising results compared to the previous
models.
Furthermore, GPT models have proven extraordinary competences for Natural Language
Generation (NLG) and MT together with GPT-3. They attain competitive translation quality for
high-resource languages but have restricted capabilities for low-resource languages. Hybrid
approaches that join GPT models with other translation systems can enhance translation quality
further, Maysa, (2023). GPT-3 has been evaluated for translating specialised Arabic text to
English and has shown generally comprehensible translations but struggles with capturing
nuances and cultural context, (Hendy., A, et al., 2023). Chat GPT, another GPT model, has been
evaluated for its understanding ability and performs well on inference tasks but inadequate in
tackling rewording and resemblance tasks. Overall, GPT models have promising potential for

20
translation tasks, but further research is needed to expand their abilities and address their
limitations, (Hasin, R., et al., 2023) and (Mamatha, A., et al., 2023). It is based on these reasons
that translators need to understand these transformer models potentials and application for better
results.
Also, BERT, GPT, and T5 transformer architectures are all related to NLP. BERT combines
Transformers with a neighbor-attention mechanism to improve relation extraction tasks in
biomedical literature, (Po-Ting, 2021). GPT is a Transformer-based language model that has
achieved groundbreaking results in tasks like poetry generation and summarisation, (Topal,
2021). Transformers, in general, have revolutionised NLP by addressing issues like vanishing
gradient problems and enabling parallelisation in sentence processing, (Grail, 2021). These
architectures have been applied to various tasks, including downstream tasks in NLP, such as text
generation and summarisation, (Zheng, 2021). BERT, in particular, is an implementation of the
Transformer architecture developed by Google, (Turton, 2021).
2.1. Comparative Study of the Variant Models
A comparative analysis of the variants BERT, GPT, and T5 models is made below: BERT is a
transformer-based model designed for Natural Language Understanding (NLU) tasks. For Zaki,
(27) NLU implies “the understanding of language by linguists and translators”. It is fully
linguistics, as it deals with each system of phonology, morphology, syntax and pragmatics.
It pre-trains a language model on a large corpus of text in a bidirectional manner, enabling it to
capture context from both the left and right sides of a word. The Strengths in BERT excel in tasks
requiring a deep understanding of the context, such as question answering and text completion.
Its bidirectional approach allows it to capture intricate relationships between words in a sentence.
The limitation of BERT requires large amounts of data and computational resources for training.
It processes text sequentially, making it computationally intensive and slower for long texts.
GPT, developed by Open AI, is another transformer-based model introduced in 2018. Unlike
BERT, GPT is designed for NLG tasks. For Zaki, (27), NLG is a “computer process that
generates natural text and speech from pre-defined data”. It is pre-trained to predict the next word
in a sentence, enabling it to generate coherent and contextually appropriate text. The strengths of
GPT are excellent for tasks like text generation, translation, and creative writing. It generates text
auto regressively, meaning it predicts one word at a time, which can be advantageous for certain
applications. The limitations of GPT’s unidirectional nature might limit its understanding of
context, as it only considers the preceding words in a sentence. It might face challenges in tasks
requiring precise comprehension and extraction of information.
T5, introduced by Google Research in 2019, is a versatile transformer-based model. Unlike
BERT and GPT, T5 frames all NLP tasks as text-to-text tasks, unifying different tasks under a
common text-based format. It is pre-trained to convert one form of text into another, allowing it
to handle a wide array of tasks. The strengths of T5’s text-to-text framework simplify the task-
specific architectures, making it highly flexible and easy to apply to various NLP tasks. It
achieves state-of-the-art performance across multiple benchmarks due to its unified architecture.
The limitations of T5’s performance might be prejudiced by the superiority and variety of the
training data for diverse tasks. Training and fine-tuning T5 models can be resource-intensive,
especially for large-scale applications.
The variant models BERT, GPT, and T5 have been compared in various studies. A study found
that BERT achieved higher accuracy compared to other models on the Stanford Question
Answering Dataset (SQuAD), (Melek, 2023). Another study evaluated the performance of GPT

21
and BERT models in detecting protein-protein interactions (PPIs) and found that BERT-based
models achieved the best overall performance, (Devshree, 2020). GPT-4, despite not being
explicitly trained for biomedical texts, showed similar performance to the best BERT models in
detecting PPIs, (Hasin, 2023). Additionally, a comparative analysis of DL models for sentiment
prediction in customer reviews found that fine-tuned BERT outperformed other DL models in
terms of accuracy and performance measures, (Anandan, 2022). Overall, these studies highlight
the effectiveness of BERT and GPT models in various NLP tasks, including question answering,
PPI identification, and sentiment prediction.
Furthermore, BERT excels in tasks requiring deep contextual understanding, making it suitable
for applications like question answering and sentiment analysis. GPT is ideal for text generation
tasks, such as creative writing and story generation, where coherent and contextually relevant text
is essential.T5 offers a unified solution for various NLP tasks with its text-to-text framework,
enabling easy adaptation and fine-tuning for specific applications.
3. APPLICATIONS OF BERT, GPT, AND T5 TRANSFORMERS MODELS IN
TRANSLATION TECHNOLOGY
The variant models BERT, GPT, and T5 have practical applications in the field of translation
technology. GPT has been used for question-answering systems and can be applied to further
NLP tasks such as text classification, Named Entity Recognition (NER), and language
translation, (Dai, 2023). According to Zaki, (26) NER is “the procedure that a machine follows in
finding the name entities”. The subtask of information extraction in Artificial Intelligence (AI)
known as NER looks for and verifies named entities mentioned in the unstructured text that fall
into pre - defined categories like names of people, organisations, places, medical codes, time
expressions, quantities, monetary values, and percentages. BERT has been explored for Neural
Machine Translation (NMT) and has shown promising results when used as contextual
embedding in the encoder and decoder of the NMT model, (Zhu, 2020),(Sabharwal et al., 2021).
It has been used for supervised NMT tasks, achieving state-of-the-art results on benchmark
datasets, (Clinchant, 2019) and (Garg, 2020). T5 (text-to-text transfer transformer) can be used
for translation tasks, as it has been shown to achieve high translation quality when fine-tuned on
translation datasets.
BERT, GPT, and T5 are advanced NLP models with practical applications in translation
technology. Some practical applications of these models in the field of translation are: BERT-
based models have been used for improving translation quality by generating contextual
embeddings of words and phrases in departed and arrived languages. GPT-based models can be
fine-tuned for translation tasks, where the model generates fluent and contextually relevant
translations given a source text. T5 models can be applied to translation tasks by framing
translation as a text-to-text problem, where the input is a text prompt in the departed language,
and the output is the translated text in the arrived language. The field of AI and NLP is rapidly
evolving, and new applications and advancements. A transformer model is presented in the figure
below:

22

The translation process in the transformer model starts from a sentence or text in the source
language as input and ends in the target language as output. The transfer follows certain
procedures from encoder, input, and output embeddings such as self-attention, feed-forward, and
to decoder following linear and SoftMax calculating output probabilities for the translation result.
4. METHODOLOGY
The population of the study focuses on the comparison between BERT, GPT, and T5 transformer
models in revolutionising translation. The study tries to establish the application of these models
in translation technology. It is based on the facts and results of the models in translations and
from translation experts. The theory of meaning and the study applies a comparative, scientific
and technical approach to compare and analyse the facts about transformer models.
5. RESEARCH FINDINGS
The transformer-based models BERT, GPT, and T5 are powerful and have significantly
contributed to the advancement of NLP tasks, including translation technology. While they have
distinct architectures and purposes, they have collectively pushed the boundaries of MT and have
been instrumental in revolutionising the field. They are logically presented based on their
introduction as follows: BERT was introduced by Google in 2018 and revolutionised the way
researchers approached NLU tasks. Unlike previous models, BERT is bidirectional and can
understand the context of a word based on its surrounding words in a sentence. It has been used
in various ways to enhance translation technology, particularly in the area of contextual word
embeddings. Translation models utilising BERT embeddings can generate more accurate and
contextually relevant translations, by understanding the context of words in both source and
target languages.

23
T5 was introduced by Google in 2019 and takes a unified approach to various NLP tasks,
including translation. Instead of treating translation as a sequence-to-sequence task, T5 frames all
NLP tasks as text-to-text tasks. This means that both the input and output are treated as text
strings. For translation, the source language text is treated as the input text, and the target
language text is treated as the output text. This approach allows T5 to handle translation
consistently with other NLP tasks. T5 models have achieved state-of-the-art results in MT tasks,
by pre-training on a large corpus of text and fine-tuning on translation-specific data.
GPT was developed by Open AI and focuses on generating coherent and contextually relevant
text based on a given prompt. While GPT is not specifically designed for translation tasks, its
ability to generate human-like text has been harnessed in certain translation applications. GPT-
based systems can provide reasonably good translations, especially for shorter texts. By
conditioning the model on a source language prompt and allowing it to generate text in the target
language, However, its unidirectional nature (it generates text from left to right) can limit its
effectiveness for some translation tasks where understanding the entire sentence context is
crucial.
These variant models brought about the revolution from their ability to capture complex linguistic
patterns, contextual nuances and semantic meanings in both source and target languages.
Researchers, practitioners and developers continue to develop and build upon these innovations
leading to more advancements in MT systems.
6. RESEARCH IMPLICATIONS
BERT, GPT, and T5 are all powerful transformer-based models that have significantly impacted
various NLP tasks, including translation technology. Some of the implications of these models in
the field of translation are:
- BERT, GPT, and T5 models have demonstrated superior performance in understanding
context and generating fluent and contextually relevant translations. These models can
capture complex linguistic patterns and nuances, leading to improved translation quality,
especially for ambiguous or context-dependent phrases.
- BERT, being a bidirectional model, captures contextual information effectively. It
understands the meaning of words in the context of surrounding words, enabling it to
produce contextually accurate translations. This is particularly useful for languages with
ambiguous word meanings.
- GPT is a generative model, that can produce coherent and contextually appropriate
translations. Its ability to generate text sequentially allows it to create fluent translations
that follow the natural flow of the target language. GPT-based models can generate
longer translations with consistent style and tone.
- T5, based on a text-to-text approach, treats all NLP tasks, including translation, as
converting one kind of text to another. This framework allows T5 to handle translation in
a unified manner, making it versatile and adaptable to various language pairs and
domains. T5’s ability to frame translation as a text-generation task contributes to its
effectiveness in this area.
- GPT and T5 models have shown promising results in few-shot and zero-shot translation
scenarios. Few-shot translation involves providing the model with a few examples of the
translation task, allowing it to generalise and translate similar phrases accurately. Zero-

24
shot translation involves translating language pairs the model has never seen during
training. Both capabilities open the door for more flexible and adaptable translation
systems.
- These transformer models can be fine-tuned for multiple languages, enabling the
development of multilingual translation systems. This is especially valuable for
languages with limited labeled data, as these models can leverage the knowledge learned
from high-resource languages to advance translation quality for low-resource languages.
- BERT, GPT, and T5 models can be fine-tuned on specific domains or topics, allowing
developers to create domain-specific translation systems. The customisation enhances the
accuracy and relevance of translations in specialised fields such as legal, medical, or
technical translations.
While these models offer remarkable capabilities, challenges such as biases in training data,
ethical concerns related to content manipulation, and the potential for reinforcing existing
stereotypes in translations need to be addressed. Researchers and practitioners must be mindful of
these issues while deploying these models in real-world applications. In summary, BERT, GPT,
and T5 transformer models have significantly advanced the field of translation technology by
providing state-of-the-art solutions for various translation challenges. Their ability to understand
context, generate fluent translations, handle multilingual tasks, and adapt to specific domains
makes them pivotal in the development of advanced and versatile translation systems. However,
it is essential to handle ethical concerns and biases to guarantee accountable and reasonable use
of these technologies in translation applications.
7. CONCLUSION
The conclusion summarises the key findings of the study and emphasises the significance of
BERT, GPT, and T5 models in revolutionising translation technology. It highlights the potential
of these models to bridge language barriers, improve cross-cultural communication, and pave the
way for more accurate and natural translations in the future. This study has helped to provide
readers and translators with a thorough understanding of the transformative impact of BERT,
GPT, and T5 models on translation technology, offering valuable insights for researchers,
practitioners, and enthusiasts in the field of NLP and MT.
8. RECOMMENDATIONS
The rapid advancement of AI-driven translation tools necessitates translators to modify their
approaches to optimise the advantages and minimise the drawbacks of these technologies. When
AI is used effectively and with a thorough awareness of both its strengths and weaknesses, it can
greatly improve human-AI cooperation and collaboration in translation. The suggestions in this
study are meant to assist educators of translation in preparing language specialists to operate
efficiently using state-of-the-art technologies, they should do the following:
- Pay attention to creative translation and specialised translation fields,
- Offer a thorough investigation of AI-based translation systems,
- Develop computational and programming abilities,
- Pay attention to proofreading and modifying translations,
- Create more challenging evaluation assignments.
