+# MatPROV
+
+**MatPROV** is a dataset of materials synthesis procedures extracted from scientific papers using large language models (LLMs) and represented in [PROV-DM](https://www.w3.org/TR/prov-dm/)–compliant structures.

+
+## Files
+

+
+## Data format
+
+The main dataset file is `MatPROV.jsonl`, where each line corresponds to one paper’s structured record.
+Each record contains:
+
+- `doi`: DOI of the source paper  
+- `label`: Identifier for the extracted synthesis procedure, encoding the material's chemical composition and key synthesis characteristics (e.g., `CuGaTe2_ball-milling`)  
+- `prov_jsonld`: A PROV-JSONLD structure describing the synthesis procedure  
+
+### Example
+
+```json
+{
+  "doi": "10.1002/advs.201600035",
+  "label": "Fe1+xNb0.75Ti0.25Sb_composition variation",
+  "prov_jsonld": {
+    "@context": [
+      {"xsd": "http://www.w3.org/2001/XMLSchema#", "prov": "http://www.w3.org/ns/prov#"},
+      "https://openprovenance.org/prov-jsonld/context.jsonld",
+      "URL of MatPROV's context schema omitted for double-blind review"
+    ],
+    "@graph": [
+      {
+        "@type": "Entity",
+        "@id": "e1",
+        "label": [{"@value": "Fe", "@language": "EN"}],
+        "type": [{"@value": "material"}],
+        "matprov:purity": [{"@value": "99.97%", "@type": "xsd:string"}]
+      }
+      ...
+    ]
+  }
+}
+```
+
+## Dataset construction summary
+
+- Source papers collected: 1648
+- **Relevant Text Extraction**
+  - 32 papers contained no synthesis-related text
+  - → 1616 papers remained
+- **Synthesis Procedure Extraction**
+  - 48 papers contained no synthesis procedure
+  - → 1568 papers remained (final dataset)
+
+The DOIs of these 1568 papers and their extracted data are included in `MatPROV.jsonl`.
+For details on the filtering status of each DOI, see `doi_status.csv`.
+
+## Ground Truth annotations
+
+- A subset of papers was manually annotated by a single domain expert.
+- Files are stored in `ground-truth/` and named as `<DOI>.json`.
+
+## Few-shot examples
+
+- Prompt examples used for LLM extraction are provided in `few-shot/`.
+- Files are stored in `few-shot/` and named as `<DOI>.txt`.
