Alt Text Generation for Educational Content Repository

This case study outlines a solution provided by Lumina Datamatics for a client specializing in educational materials. The client faced challenges in generating alt text for over 130,000 images, which was necessary for accessibility compliance. Manual production of alt text was impractical due to time and financial constraints, and the varying metadata across images complicated the integration process. Lumina Datamatics developed a dynamic workflow that combined artificial intelligence and human review to address these challenges. AI programs utilizing Convolutional Neural Networks analyzed the images and generated descriptive content. Pre-trained models and language algorithms were employed to create meaningful alt text, incorporating existing metadata where possible. The solution allowed for swift generation of alt text, improving user experience and compliance with accessibility standards. The client achieved significant cost savings, reducing their budget by 75%, while ensuring high-quality, contextually relevant descriptions for their image repository.
