LeMat-Synth: a multi-modal toolbox to curate broad synthesis procedure databases from scientific literature
LeMat-Synth introduces a multi-modal toolbox leveraging LLMs and VLMs to extract, standardize, and structure synthesis protocols and performance data from 81k open-access materials science papers. This creates LeMat-Synth (v1.0), a dataset of 2.5k structured synthesis procedures spanning 35 methods and 16 material classes. The system achieves high accuracy, validated by expert annotations and an LLM-as-a-judge framework, and provides an extensible open-source infrastructure for data-driven materials discovery.

Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
Comprehensive Corpus Aggregation
LeMat-Synth aggregates a vast corpus from arXiv, ChemRxiv, and OMG24, identifying over 80.9k publications with explicit synthesis procedures. Full-text and figures are parsed using advanced PDF tools, then standardized for consistent formatting. This extensive curation forms the foundation of the LeMat-Synth (v1.0) dataset, enabling scalable analysis.
- 81k+ open-access papers processed.
- Integration of arXiv, ChemRxiv, and OMG24 sources.
- Standardized PDF parsing and post-processing.
Structured Ontology and LLM Pipeline
A formal ontology defines synthesis as discrete operations, capturing actions, precursors, and conditions, implemented via a typed Pydantic schema. Using DSPy with Gemini 2.0 Flash, the system identifies target materials, extracts multi-material syntheses, and generates structured JSON outputs conforming to the ontology. This ensures consistent, machine-readable protocols.
- Domain-specific ontology for 35 synthesis methods.
- DSPy framework with Gemini 2.0 Flash for extraction.
- Structured JSON outputs from text.
Multi-modal VLM for Quantitative Data
Quantitative data from charts and graphs is extracted via a three-stage pipeline: DINO segments multi-panel figures into subplots, ResNet-152 classifies quantitative plots, and Claude 4 Sonnet digitizes charts into (x,y) coordinates and metadata. This process converts visual information into structured data, complementing textual extractions.
- DINO for zero-shot visual segmentation of figures.
- ResNet-152 for classifying quantitative plots.
- Claude 4 Sonnet for digitizing (x,y) coordinates.
Robust Human-LLM Hybrid Evaluation
A comprehensive evaluation protocol assesses extraction accuracy and generalizability using expert annotations and an LLM-as-a-judge framework (Gemini-2.0-flash). A strong Spearman correlation (p=0.72) between human and LLM scores validates the system. This scalable approach confirms high-quality extraction across diverse synthesis methods and material categories.
- Expert annotations for gold-standard benchmark.
- LLM-as-a-judge framework for scalable evaluation.
- High Spearman correlation (0.72) with human scores.

Case Study: LLM-as-a-Judge Validation
Challenge: Evaluating extraction quality at scale without extensive human annotation.
Solution: Implemented a Gemini-2.0-flash LLM-as-a-judge framework, mimicking expert evaluation rubrics to score 2.5k synthesis extractions automatically.
Results: Achieved an average Spearman correlation of p=0.72 with human expert annotations, demonstrating reliable and scalable quality assessment across criteria like material extraction and process steps. This enables broad applicability of the ontology to materials science.
