Within the ever-evolving landscape of computational linguistics, bridging language barriers has led to remarkable innovations, particularly in regions characterised by a wealthy tapestry of languages. Southeast Asia, with its linguistic diversity, presents a novel challenge for language technology. Traditional models often need assistance to know the nuanced differences and similarities across languages akin to Indonesian, Thai, Vietnamese, Malay, and Lao, which significantly hampers their applicability in real-world scenarios.

A team of researchers from the Sea AI Lab and Singapore University of Technology and Design has introduced “Sailor,” an ambitious suite of language models tailored to the linguistic intricacies of the Southeast Asian region. Unlike conventional approaches which may depend on generic, one-size-fits-all models, Sailor distinguishes itself through a meticulous data handling process that features careful curation, aggressive deduplication, and progressive mixture algorithms. This technique ensures that Sailor is deeply attuned to the linguistic nuances of the Southeast Asian languages, thereby facilitating more accurate and meaningful text generation and comprehension.

Built upon the robust Qwen 1.5 models, Sailor has been pretrained on an expansive corpus that ranges between 200 and 400 billion tokens, with a deliberate give attention to languages from the Southeast Asian region. This extensive pretraining has equipped Sailor with the potential to know and generate text across a broad spectrum of languages, thereby setting a brand new precedent in the sphere of multilingual language technology. The model variants offered by Sailor, starting from 0.5B to 7B in size, are designed to satisfy diverse computational needs, ensuring broad accessibility and utility.

The efficacy of Sailor models is underscored by their performance across various benchmarking tasks, a testament to their superior design and implementation. In tasks akin to query answering, commonsense reasoning, reading comprehension, and standardized exams tailored to Southeast Asian languages, Sailor models have demonstrated remarkable proficiency. As an example, within the question-answering category, the Sailor-7B model achieved a 57.88% exact match rating on the XQuAD (Thai) benchmark, a 60.53% rating on TydiQA (Indonesian), and 53.81% on XQuAD (Vietnamese), outperforming its predecessors and establishing latest benchmarks for accuracy and reliability.

Sailor’s performance in commonsense reasoning and reading comprehension further exemplifies its advanced understanding capabilities. Within the XCOPA benchmark, the Sailor-7B model attained an accuracy of 72.2% across Thai, Indonesian, and Vietnamese tasks, showcasing its adeptness at interpreting and reasoning with complex text. Similarly, in reading comprehension, evaluated through the Belebele benchmark, Sailor-7B’s scores were impressively high, with 44.33% in Indonesian, 45.33% in Vietnamese, and 41.56% in Thai.

In conclusion, Sailor’s introduction is a big step forward in the hunt for comprehensive language models that may navigate the complex linguistic landscape of Southeast Asia. By combining advanced methodologies with an inclusive approach to language diversity, Sailor addresses the pressing need for tailored language technologies within the region and offers a blueprint for future advancements. The success of Sailor in benchmarking tasks highlights the potential of specialised models in enhancing our understanding and interaction in the sphere of computational linguistics.
