I recently shared my thoughts on LinkedIn about the potential of AI Agents and how this technology could be utilised to develop self-managing AI systems. In the case study I discussed explored methods for monitoring hundreds of news articles and presenting the most relevant ones to a Key Account Manager.
Building upon this concept, I discovered a fascinating academic paper titled “Beyond Human Translation: Harnessing Multi-Agent Collaboration for Translating Ultra-Long Literary Texts” by Minghao Wu, Yulin Yuan, Gholamreza Haffari, and Longyue Wang, which delves into a similar multi-agent approach but applied to the complex domain of literary translation.
The paper introduces TRANSAGENTS, a groundbreaking multi-agent system based on large language models (LLMs) designed for literary translation. By leveraging the collective capabilities of multiple agents, TRANSAGENTS mirrors the traditional translation publication process, addressing the intricate demands of translating literary works. The system establishes virtual agent profiles with detailed attributes to enhance the realism of the translation process simulation.
The authors propose two innovative evaluation strategies: Monolingual Human Preference (MHP) and Bilingual LLM Preference (BLP). MHP assesses translations from the perspective of monolingual target language readers, focusing on fluidity, readability, and cultural appropriateness, without influence from the original text. BLP employs advanced LLMs to directly compare translations with the original texts. Despite lower d-BLEU scores, empirical findings demonstrate that TRANSAGENTS translations are preferred by both human evaluators and LLMs over human-written references, particularly for genres requiring domain-specific knowledge.
Case studies highlight TRANSAGENTS’ strengths in producing diverse, vivid descriptions and adapting to cultural contexts. However, significant content omission is identified as a limitation. They claim a cost analysis indicates that using TRANSAGENTS can reduce literary translation costs by 80x compared to professional human translators.
TRANSAGENTS employs two key agent collaboration strategies: Addition-by-Subtraction and Trilateral Collaboration. Addition-by-Subtraction involves an Addition agent extracting relevant information and a Subtraction agent eliminating redundancies. Trilateral Collaboration divides roles into Action (implementing instructions), Critique (providing feedback), and Judgment (final decision-making). The translation workflow consists of a Preparation stage (team selection, translation guideline documentation) and an Execution stage (translation, localization, proofreading, final review).
Standard evaluation using d-BLEU shows that TRANSAGENTS performs poorly compared to baselines. However, the authors argue that d-BLEU has limitations in assessing literary translation quality. The preference-based evaluation methods also have some limitations related to document segmentation, evaluator demographics, scale, and reference quality, which future research should address.
This paper makes significant contributions by introducing a novel LLM-based multi-agent approach to literary translation, proposing innovative human and LLM-based evaluation methods, and providing in-depth analyses of the system’s strengths and weaknesses. While there are limitations to the current work, it lays important groundwork for future research and I’m sure the tool vendors are watching this very closely.
