Large language models (LLMs) exhibit outstanding performance in machine translation via in-context learning. In contrast to sentence-level translation, document-level translation (DOCMT) by LLMs based on in-context learning faces two major challenges: firstly, document translations generated by LLMs are often incoherent; secondly, the length of demonstration for in-context learning is usually limited. To address these issues, we propose a Context-Aware Prompting method (CAP), which enables LLMs to generate more accurate, cohesive, and coherent translations via in-context learning. CAP takes into account multi-level attention, selects the most relevant sentences to the current one as context, and then generates a summary from these collected sentences. Subsequently, sentences most similar to the summary are retrieved from the datastore as demonstrations, which effectively guide LLMs in generating cohesive and coherent translations. We conduct extensive experiments across various DOCMT tasks, and the results demonstrate the effectiveness of our approach, particularly in zero pronoun translation (ZPT) and literary translation tasks.

通过上下文学习，我们提出了一种上下文感知提示方法（CAP），使得大型语言模型能够通过上下文学习生成更准确、连贯、一致的翻译。CAP结合多级注意力，在当前句子中选择与之最相关的句子作为上下文，从这些句子中生成一个摘要。随后，从数据存储中检索与摘要最相似的句子作为演示，有效地指导大型语言模型生成连贯一致的翻译。我们在各种文档级机器翻译任务中进行了大量的实验，结果表明我们的方法在零代词翻译（ZPT）和文学翻译任务中特别有效。
