While the current approach demonstrates significant advancements in literary translation, several limitations remain that could be addressed for further improvement:
Limited Contextual Awareness: The Incremental Decoding framework relies on a fixed number of previous sentences for context. This may not be sufficient for capturing long-range dependencies in complex narratives, where earlier events or themes can influence later parts of the text. To improve this, the model could implement a dynamic context window that adjusts based on the narrative structure, allowing it to consider a broader range of preceding sentences.
Handling Ambiguities and Nuances: Literary texts often contain ambiguities, metaphors, and cultural references that may not translate directly. The current model may struggle with these nuances. Enhancing the model's ability to recognize and interpret such elements through additional training on annotated literary datasets could improve its translation quality.
Incorporating Authorial Voice: Preserving the author's unique voice and style is crucial in literary translation. The current approach may not fully capture these subtleties. Future improvements could involve training the model on a wider variety of authors and styles, allowing it to learn and replicate different literary voices more effectively.
Evaluation Metrics: The reliance on BLEU scores for evaluation may not fully capture the quality of literary translations, which often require subjective assessments of style and coherence. Incorporating human evaluations or developing new metrics that account for literary qualities could provide a more comprehensive assessment of translation quality.
Scalability and Efficiency: As the model scales to handle larger texts or more complex literary works, computational efficiency may become a concern. Exploring model compression techniques or more efficient architectures could help maintain performance while reducing resource requirements.
By addressing these limitations, the approach can be refined to tackle the complexities of literary translation more effectively, resulting in translations that are not only accurate but also rich in literary quality.
