The HOLiFOOD infrastructure

The HOLiFOOD infrastructure is a sophisticated, AI-driven platform specifically designed to enhance food safety measures. This platform represents an innovative integration of AI models and robust data management systems, aimed at providing advanced predictive analytics essential for contemporary food safety practices.


Components of the HOLiFOOD Infrastructure

  • Data Layer
    • This foundational layer is tasked with managing a wide array of data types. It encompasses both structured and unstructured data segments.
    • Structured Data Management: Utilizes relational database management systems for efficient storage and retrieval of structured data originating from various work packages.
    • Unstructured Data Management: Leverages Elastic search databases for handling unstructured data forms such as laboratory test results and public food safety announcements.
    • This layer plays a crucial role in gathering, cleaning, and preparing data, which forms the backbone for training sophisticated AI models.
  • AI Management Layer
    • Serving as the central hub of the infrastructure, this layer is dedicated to AI Model Management.
    • It effectively hosts and executes trained AI models, leveraging the capabilities of Creme’s infrastructure to ensure these models are always ready for deployment.
    • This layer is instrumental in ensuring that the transition from data processing to AI model implementation is seamless and efficient.
  • AI Services Layer
    • Houses critical components such as the Timeseries & Forecasting Engine, integral to the platform’s predictive capabilities.
    • The Predictions Engine, part of this layer, utilizes advanced forecasting algorithms to analyze incident data as time series.
    • This functionality allows the AI models to not just analyze past and present data but also to project future trends and incident numbers, enhancing the platform’s predictive accuracy and utility.
  • Interface Layer
    • Positioned as the uppermost layer, it serves as the primary point of interaction with external systems.
    • Includes innovative components like the Federated Querying Module, which enables a distributed querying mechanism across different data sources, thus enhancing the platform’s reach and efficiency.
    • An API Gateway is also included, ensuring secure and managed access to the services and data offered by the underlying layers.


Elaborate on Stakeholder Requirements

  • Internal Stakeholder Requirements
    • Derived from detailed internal interviews with leaders of WPs 1 and 2, focusing on identifying the essential requirements for the technical development of the HOLiFOOD infrastructure.
    • A structured approach to these interviews was employed to comprehensively understand specific needs, ranging from data types, storage, and access requirements to handling sensitive data.
  • External Stakeholders (Living Labs)
    • Insights from the Synergy Days event provided valuable information about the expectations and requirements of external stakeholders regarding AI tools in food safety.
    • These insights included a strong inclination towards AI-driven optimization, efficient standardization, and cost-effective solutions in food safety.
    • The feedback pointed out the technical necessities, like high-performance computing infrastructure and qualified staff, and highlighted the challenges, such as digital resource availability and financial constraints.
