This benchmark covers original non-disclosure agreement text, amendments, clauses from different versions, and claims about current obligations, terms, or clause content. It includes cases involving unclear version relationships, incomplete amendment histories, and conflicting clauses, with labels indicating whether the available documents sufficiently support each claim and explaining the basis for that judgment. It supports the training and evaluation of legal document verifiers, particularly their ability to identify version issues, assess evidentiary sufficiency, and explain their conclusions.

Technical Specifications
| Field | Type | Description |
|---|---|---|
| file_name | string | File name |
| evidence_basis | array | Lists the clauses, documents, or version clues supporting the verification outcome. Entries may include clause numbers and relevant excerpts. |
| reasoning_summary | string | Explains how the document contents, version relationships, and clause conflicts support the verification outcome. |
| verification_claim | string | A claim about a current obligation, term, or clause content that must be verified against the supplied agreement materials. |
| base_agreement_text | string | The original non-disclosure agreement or the agreement text used as the starting point for comparison. |
| current_term_summary | string | Summarizes the current obligation, term, or relevant clause content that can be established from the materials, or explains why it cannot be determined. |
| identified_conflicts | array | Lists conflicts relevant to the claim among clauses in different versions or documents. This may be an empty array when no conflict is identified. |
| verification_outcome | string | A summary conclusion about the relationship between the claim and the available evidence. |
| insufficiency_reasons | array | Lists the reasons the claim cannot be sufficiently determined. This may be an empty array when the evidence is sufficient. |

FAQ
Frequently Asked Questions
- What does the benchmark contain?
- It includes base NDA text, amendment and other version texts, claims to verify, and annotations such as whether each claim can be sufficiently determined, the verification outcome, reasons for insufficient evidence, and relevant supporting clauses. It focuses on how version relationships and clause conflicts affect the assessment.
- How should evidence sufficiency be assessed?
- Assess whether the supplied agreement text, amendment documents, version clues, and relevant clauses are enough to determine the current obligation or term. Unclear version relationships, missing links in the amendment history, or unresolved clause conflicts should be treated as potential evidence gaps and explained in the reasoning.
- What are suitable use cases?
- The benchmark can support training and evaluation of legal document verifiers, testing contract review tools, and research on version tracking and evidence sufficiency. It is intended for model development and evaluation and does not replace legal advice from a qualified lawyer on a specific agreement.
- How can I access the data and check its license?
- Consult the dataset product page for available versions, delivery details, and license terms, and follow the stated license scope. Before use, confirm that activities such as data processing, redistribution, and commercial use are permitted under the applicable terms.
