Unverified50% confidenceFactExact time
Document information extraction is a mature research direction in natural language processing; traditional approaches rely on rule templates or regular expressions, deep learning methods train sequence labeling or question-answering models on annotated samples, and vision-based document understanding models (such as the LayoutLM series) further jointly model text and layout.

UnverifiedInformation Extraction is a classic task in natural language processing, whose goal is to identify entities, attributes, and relations from unstructured text and convert them into structured fields; traditional approaches rely on rule templates or sequence labeling models, while extraction based on large models typically uses prompting plus structured output.76% similarUnverifiedThe extraction process of document extraction agents relies on the instruction-following capability of large language models, and input text quality directly affects field extraction accuracy.74% similarUnverifiedThe research adopts a combination of feature extraction and semantic mapping, distilling import tables, section characteristics, suspicious API calls, and so on into structured descriptions, which are then handed to the model for reasoning, so that the key binary information input to the model is presented in the form of textual semantics.73% similarUnverifiedThe paper uses manually written style examples to prompt a language model to convert original exhaustive commands into intent-centered weak instructions, batch-generating paired training data.72% similarUnverified上下文工程指系统性地设计、筛选和组织输入给大语言模型的信息，使模型在有限的上下文窗口内获得最高质量的参考材料72% similar
