针对航空航天文档异构、非结构化导致的跨产品分析难题,提出结合 KG 与 LLM 的测试数据提取和验证方法,并通过卫星电子板案例及 LLM 基准评估其性能与自动化收益。

摘要:

航空航天制造企业(如 Thales Alenia Space)设计、开发、集成、验证并确认具有高复杂度、低产量特征的产品。它们会仔细记录每个产品的所有阶段,但由于文档中数据的异构性和非结构化性质,跨产品分析颇具挑战。本文提出一种混合方法,利用知识图谱(KG)与大语言模型(LLM)相结合,提取并验证这些文档中包含的数据。我们考虑了一个聚焦于卫星电子板相关测试数据的案例研究。为此,我们扩展了 Semantic Sensor Network 本体。我们将报告的元数据存储在 KG 中,而实际测试结果存储在可通过 Virtual Knowledge Graph 访问的 parquet 中。验证过程采用基于 LLM 的方法进行管理。我们还开展了一项基准测试研究,以评估最先进的 LLM 在执行该任务时的性能。最后,我们分析了将既有的人工数据提取与验证流程自动化,以用于后续跨报告分析的成本和收益。

英文摘要:

Aerospace manufacturing companies, such as Thales Alenia Space, design, develop, integrate, verify, and validate products characterized by high complexity and low volume. They carefully document all phases for each product but analyses across products are challenging due to the heterogeneity and unstructured nature of the data in documents. In this paper, we propose a hybrid methodology that leverages Knowledge Graphs (KGs) in conjunction with Large Language Models (LLMs) to extract and validate data contained in these documents. We consider a case study focused on test data related to electronic boards for satellites. To do so, we extend the Semantic Sensor Network ontology. We store the metadata of the reports in a KG, while the actual test results are stored in parquet accessible via a Virtual Knowledge Graph. The validation process is managed using an LLM-based approach. We also conduct a benchmarking study to evaluate the performance of state-of-the-art LLMs in executing this task. Finally, we analyze the costs and benefits of automating preexisting processes of manual data extraction and validation for subsequent cross-report analyses.
