The Challenge of Corn Futures Forecasting
Accurately predicting short-term corn futures prices is a persistent challenge for agricultural stakeholders. Traditional models, often relying solely on historical price data, struggle to capture the complex, real-time dynamics influenced by information flows, market sentiment, and sudden shifts in media attention.
Our Novel Hybrid AI Approach
This study introduces a two-stage hybrid framework: an LSTM neural network for robust price-only predictions, followed by a Ridge regression residual correction. This correction integrates dynamically extracted news attention features from the GDELT Global Knowledge Graph, providing incremental predictive power without adding undue model complexity. Unlike traditional sentiment analysis, our model focuses on the intensity and persistence of news coverage, demonstrating superior predictive value in highly volatile agricultural markets.

Performance Overview: Hybrid vs. Baseline
| Model | RMSE (¢/bu) | MAE (¢/bu) | R² | DirAcc |
|---|---|---|---|---|
| LSTM Baseline | 9.024 | 5.801 | 0.991 | 0.492 |
| Hybrid (LSTM + News) | 8.998 | 5.789 | 0.991 | 0.516 |
Attention Outperforms Sentiment
A critical insight from our analysis is the profound impact of media attention intensity and persistence over traditional sentiment polarity. Ridge regression feature attribution revealed that while sentiment variables (like average tone or positive/negative share) received zero weight, attention-related features (z-scored coverage, rolling intensity, run lengths of high coverage) were dominant predictors. This indicates that how much and how long agricultural topics are covered matters more than the emotional tone of the news.
The improvements in directional accuracy were most notable during periods of moderate news intensity, suggesting that sustained, relevant information flow provides the most actionable signals for short-term price movements.
Real-Time Market Edge for Agriculture
Informed Trading & Risk Management
For commodities traders, this framework offers a significant edge. By providing a +2.4 percentage point increase in directional accuracy, especially during periods of moderate news intensity, the model helps anticipate market turns. This translates to more precise short-term hedging strategies and improved risk management, allowing for better entry and exit points in volatile corn futures markets. The transparency of the Ridge correction further enables traders to understand why a correction is suggested, building trust in the AI's recommendations.
Operational Efficiency & Reproducibility
The lightweight and modular design ensures high computational efficiency, enabling frequent retraining and real-time deployment on standard hardware. This is crucial for rapidly evolving markets where timely information is paramount. The use of open-access GDELT data and a transparent two-stage architecture makes the framework highly reproducible and scalable, reducing reliance on proprietary data or complex, opaque deep learning systems.
Beyond Corn: A Blueprint for Commodity Intelligence
This hybrid approach establishes a transferable blueprint for integrating unstructured textual data into other commodity price forecasting pipelines. Future applications could include early-warning systems for supply chain disruptions, policy impact assessments, or enhancing price predictions across various agricultural products by dynamically weighting news influence under different market conditions.
