Abstract

At present, the verification of consistency between two merchant vessel documents that address the same subject matter and are prepared or processed by different operators remains dependent on manual checks and is considerably time-consuming. Accordingly, this study aims to design and develop a document consistency comparison framework for two interrelated document sets by a multi-stage process consisting of rule-based techniques assisted by Natural Language Processing in an offline environment. The proposed framework is intended to enhance verification efficiency and processing speed while mitigating the risk of data leakage. The verification procedure comprises four sequential stages: 1) Exact Matching, 2) Fuzzy Matching, 3) Semantic Similarity, and 4) Natural Language Inference. The experiment was conducted using four categories of data comprising 2,000 files in total: 500 report files (.docx), 500 text-based reference files (.pdf), 500 image-based reference files (.pdf), and 500 gold-label files (.csv) containing ground-truth annotations for 10 target fields. These datasets were employed to assess the performance of the proposed framework using multiple evaluation metrics. The results on the same dataset used to tune the thresholds indicate that the proposed framework improves the Pass rate. For Text-based documents, the Pass rate increased from 87.90% to 96.50%, whereas for Image-based documents, it increased from 72.40% to 85.10%. The highest binary F1-scores were 0.982 and 0.920, respectively.
