contradicted | Adjacent module rows are spaced 8.0 m apart, measured center-to-center. | m | 8.0 | row_spacing | Row center-to-center spacing | Row Geometry Schedule, Table 2: "Row center-to-center spacing: 6.5 m." | direct_contradiction | Row Geometry Schedule, Table 2 | The schedule specifies a center-to-center spacing of 6.5 m, which conflicts with the claim of 8.0 m using the same measurement basis. |
supported | The minimum clearance between the finished grade and the lowest module edge in the crop lane is 2.4 m. | m | 2.4 | clearance_height | Minimum module clearance height | Field Layout Basis, Section 3.2: "At the crop-lane crossing, the lowest module edge is set 2.4 m above finished grade." | direct_support | Field Layout Basis, Section 3.2 | The excerpt states that the lowest module edge at the crop-lane crossing is 2.4 m above finished grade, matching the claimed clearance and location. |
insufficient_evidence | The peak-season midday shade fraction beneath the array is below 25%. | below 25% | shading | Peak-season midday shade fraction | Crop-Light Design Note, Section 4.1: "The modules are arranged in east-west bands to provide alternating sun and shade across the growing area." The section provides no quantified shade fraction or measurement period. | context_only | Crop-Light Design Note, Section 4.1 | The excerpt describes an alternating sun-and-shade pattern but gives no shade fraction or peak-season midday measurement. It therefore does not establish whether the claimed threshold is met. |
Agrivoltaic System Design Fact Verification Dataset
This dataset focuses on technical claims about agrivoltaic system structures and design parameters, including module layout, clearance height, row spacing, shading, and light conditions. Its structured JSON records include source evidence, verification labels, and evidence-to-claim relations. They support evaluation of whether models can verify claims against engineering materials, identify how evidence relates to a claim, and provide traceable rationales for benchmark testing and technical document review.
Technical Specifications
| Field | Type | Description |
|---|---|---|
| verdict | string | The label indicating whether the cited evidence supports the claim. |
| claim_text | string | The original technical claim about agrivoltaic system structure, layout, clearance, spacing, shading, or light conditions. |
| claimed_unit | string | The unit associated with the claimed value, when applicable; an empty string indicates that no unit is stated. |
| claimed_value | string | The value or qualitative condition asserted by the claim, represented as text to support numeric and nonnumeric claims. |
| claim_category | string | The technical category used to classify the claim. |
| parameter_name | string | The design parameter addressed by the claim, such as module clearance height, row spacing, or shading level. |
| source_evidence | string | The evidence excerpt and any available source citation or location, such as a document title, page, or section. |
| evidence_relation | string | The relationship between the cited evidence and the claim being evaluated. |
| evidence_reference | string | The specific page, section, table, figure, or passage supporting the rationale, when identifiable. |
| verification_rationale | string | A concise explanation connecting specific information in the source evidence to the verdict, rather than relying solely on general domain knowledge. |
