Party A shall accept the report by February 15, 2023.Conflict:Party A must accept the reportbeforeproject completion, which itself has a later acceptance date.Hierarchical Conflict| A general clause contradicts a specific clause, or an appendix contradicts the main body.Clause A (General): Any dispute arising under this agreement shall be resolved by arbitration in London.Clause B (Specific): Disputes related to payment defaults shall be resolved exclusively by the courts of New York.Conflict:General arbitration clause versus specific court jurisdiction for payment.Scope Conflict| Clauses define the scope of rights, obligations, or subject matter in an inconsistent manner.Clause P: This agreement covers all software developed by Party A for Party B during the project term.Clause Q: Party A retains all intellectual property rights for any derivative works created from the software during the project term.Conflict:Clause P implies Party B owns all software developed, while Clause Q allows Party A to retain rights for derivative works, potentially creating ambiguity over ownership scope.Omission/Ambiguity| While not a direct conflict, a lack of clarity or a missing essential term can lead to future disputes, which a good agent should flag.Clause R: Payment will be made upon satisfactory completion.Issue:Satisfactory completion is subjective and undefined, a potential source of future conflict.1.2 挑战对于AI而言解析这些冲突面临多重挑战自然语言理解 (NLU) 的深度法律文本充斥着专业术语、冗长的句子结构、复杂的从句和模糊的表述。简单的关键词匹配远远不够需要深层语义理解。上下文感知单一条款的意义往往依赖于合同中的其他条款、定义部分甚至序言和附录。AI需要建立全局的上下文理解。逻辑推理许多冲突并非直接的字面矛盾而是通过一系列逻辑推理才能发现的隐含矛盾。例如一个条款赋予了某方权利而另一个条款却施加了限制导致权利无法行使。规模与效率面对数万字甚至数十万字的合同如何在合理的时间内完成全面、准确的审查对计算资源和算法效率提出高要求。领域知识的整合法律合规审查不仅要看合同本身还要参照相关的法律法规、行业标准和判例法。Agent需要整合这些外部知识。二、法律合规审查 Agent 的架构设计为了应对上述挑战我们设计了一个模块化的法律合规审查 Agent。其核心思想是将复杂的审查任务分解为一系列可管理的子任务并通过流水线式的处理流程逐步实现从文本解析到冲突识别再到建议生成的全过程。2.1 Agent 高层架构概览我们的Agent可以被抽象为以下几个核心模块文档摄入与预处理模块 (Document Ingestion Preprocessing):负责将各种格式的合同文档转换为可供机器处理的纯文本并进行初步清洗。条款分割与实体识别模块 (Clause Segmentation NER):将长文本合同分解为独立的条款并识别出条款中的关键法律实体如当事人、日期、金额、管辖区等。语义理解与表示模块 (Semantic Understanding Representation):将每个条款及其识别出的实体转化为机器可理解的深层语义表示。冲突检测引擎 (Conflict Detection Engine):基于语义表示运用规则、机器学习和逻辑推理等技术识别条款间的各类冲突。法律知识库集成模块 (Legal Knowledge Base Integration):提供外部法律法规、判例、行业标准等知识用于验证冲突和生成建议。修改建议生成模块 (Recommendation Generation Module):针对检测到的冲突结合法律知识库生成具体的修改建议。下图展示了Agent的整体工作流程以文字描述代替图示[合同文档 (PDF/DOCX)] | v [1. 文档摄入与预处理] | (纯文本) v [2. 条款分割与实体识别] | (结构化条款列表 实体信息) v [3. 语义理解与表示] | (条款嵌入向量 语义图) v [4. 冲突检测引擎] --------------------------- | | v | [5. 法律知识库集成] --------------------------- | (冲突报告 相关法律依据) v [6. 修改建议生成模块] | (最终审查报告 修改建议) v [审查报告与修改建议]2.2 模块详细解析与代码示例接下来我们将逐一深入探讨每个模块的功能、技术选型和实现细节。2.2.1 文档摄入与预处理模块此模块是Agent的入口负责将不同格式的合同文档如PDF、DOCX转换为统一的纯文本格式并进行基础清洗。技术选型PDF解析PyPDF2,pdfminer.six,fitz(PyMuPDF)DOCX解析python-docxOCR (针对扫描件)Tesseract-OCR(结合Pillow进行图像处理)代码示例基础文本提取import os from PyPDF2 import PdfReader from docx import Document def extract_text_from_pdf(pdf_path: str) -

np.ndarray: 获取条款的语义嵌入向量。 embedding model.encode(clause_text) return embedding # 示例使用 if __name__ __main__: clause1 Party A shall deliver the Goods to Party Bs warehouse by March 15, 2023. clause2 The delivery date for the products is on or before March 10, 2023. clause3 Party A is responsible for the quality assurance of the delivered items. embedding1 get_clause_embedding(clause1) embedding2 get_clause_embedding(clause2) embedding3 get_clause_embedding(clause3) print(Embedding for Clause 1 shape:, embedding1.shape) # 计算语义相似度 from sklearn.metrics.pairwise import cosine_similarity similarity_1_2 cosine_similarity(embedding1.reshape(1, -1), embedding2.reshape(1, -1))[0][0] similarity_1_3 cosine_similarity(embedding1.reshape(1, -1), embedding3.reshape(1, -1))[0][0] print(fSimilarity between Clause 1 and Clause 2: {similarity_1_2:.4f}) print(fSimilarity between Clause 1 and Clause 3: {similarity_1_3:.4f}) # 可以看到语义相似的条款1和2会有更高的相似度分数这为冲突检测提供了基础。2.2.4 冲突检测引擎这是Agent的核心推理模块负责识别条款间的矛盾。它会结合多种策略从不同层面发现冲突。技术选型规则匹配基于关键词、否定词、特定短语如 notwithstanding, subject to, except that和实体关系的精确匹配。语义相似度与矛盾检测利用文本嵌入计算条款间的相似度。对于高相似度的条款对进一步使用更专业的矛盾检测模型如基于自然语言推理NLI任务微调的模型来判断是否存在逻辑矛盾。逻辑推理构建条款的谓词逻辑表示并使用SMTSatisfiability Modulo Theories求解器或Datalog等技术进行一致性检查。这对于发现隐含冲突尤其有效。知识图谱推理如果构建了知识图谱可以通过图遍历和图模式匹配来发现不一致性。代码示例基于语义相似度和简单规则的冲突检测from sklearn.metrics.pairwise import cosine_similarity import numpy as np import itertools # 假设我们有以下已嵌入的条款 # embeddings [emb1, emb2, emb3, ...] # clauses [clause_text1, clause_text2, clause_text3, ...] def detect_conflicts(clauses: list[str], embeddings: list[np.ndarray], similarity_threshold: float 0.8) -

Refer to [NY_UCC_2-201]. elif priority conflict in prompt.lower(): return Recommendation: Clarify the precedence of Clause 3 over Clause 4 by adding To the extent of any conflict, Clause 3 shall prevail over Clause 4. This resolves ambiguity regarding notwithstanding and subject to phrases.

This prevents future disputes. Refer to [PAYMENT_TERMS_BEST_PRACTICE]. else: return Recommendation: Review the conflicting clauses with legal counsel for precise wording.
