WikiVision: Visual similarity search tool for Wikimedia Commons Open, Needs Triage | **Tags:** Toolforge, Wikimedia-Commons, Computer-Vision --- ## WikiVision Tool Proposal ### Description This proposal introduces WikiVision, a visual similarity search tool for Wikimedia Commons that enables users to find visually similar images using computer vision technology. Users can upload an image or reference existing Commons files to discover related visual content across the repository. **Distinction from existing search**: Traditional Commons search relies on text-based metadata, categories, and descriptions. WikiVision provides visual content analysis to discover relationships that aren't captured in textual descriptions, enabling semantic visual discovery across Commons' media files. **Motivation**: Wikimedia Commons hosts over 100 million media files, making visual content discovery challenging through traditional text-based search alone. Many valuable images remain hidden due to inadequate metadata or language barriers. Visual similarity search addresses this gap by enabling discovery based on image content rather than textual descriptions, benefiting researchers, educators, content creators, and accessibility advocates who need alternative ways to explore visual relationships. ### Planned Features #### Core Functionality 1. **Visual Similarity Search** • Upload image files to find similar content in Commons • Search by Commons filename or URL reference • Display results with similarity scores and metadata • Basic filtering by similarity threshold and result limits 2. **Web Interface** • Drag-and-drop file upload capability • Integration with Commons API for metadata retrieval • Mobile-friendly responsive design • Direct links to Commons file pages 3. **Search Modes** • Semantic similarity: Find images with similar subjects/concepts • Visual similarity: Match composition, colors, and visual elements • Cross-category discovery: Find connections across different Commons categories ### Technical Implementation The tool implements a computer vision pipeline with the following components: #### 1. Feature Extraction • Pre-trained computer vision models (CLIP or similar) to extract visual features from Commons images • Batch processing of existing Commons images to build searchable index • Efficient vector storage for fast similarity matching #### 2. Web Application • Flask/FastAPI backend hosted on Wikimedia Toolforge • Responsive web interface for image upload and search • Integration with Commons API for metadata and file information • Real-time similarity search against pre-computed feature database #### 3. Search Processing • Compare uploaded images against indexed Commons images • Return ranked results with similarity scores • Filter and format results with Commons metadata ### Example Use Cases #### Use Case 1: Educational Content Discovery **User Command**: Teacher uploads an image of the Mona Lisa to find similar Renaissance artwork. **System Response**: WikiVision returns visually similar Renaissance portraits from Commons, including works by Da Vinci, Raphael, and contemporary artists with proper licensing information for educational use. **Benefit**: Enables educators to discover related visual content without needing specific artwork knowledge or titles. #### Use Case 2: Research and Academic Work **User Command**: Historian researching industrial machinery searches for images similar to a specific steam engine design. **System Response**: WikiVision identifies other steam engines with similar designs, construction periods, and related industrial equipment from Commons archives. **Benefit**: Accelerates research by revealing visual connections not apparent through traditional text-based search. #### Use Case 3: Content Quality Control **User Command**: Commons administrator checks recently uploaded files for potential duplicates. **System Response**: WikiVision flags images with high similarity scores for review, identifying potential duplicates or derivative works that require administrative attention. **Benefit**: Improves Commons quality through automated assistance in duplicate detection and copyright compliance. --- WikiVision addresses a significant gap in Commons content discovery by enabling visual similarity search. The tool would benefit educators, researchers, content creators, and accessibility advocates who need alternative ways to explore the visual relationships within Commons' vast media collection. The implementation leverages established computer vision techniques and Toolforge infrastructure to provide a practical solution that complements existing text-based search capabilities. ## Risk Assessment ### Technical Risks - **Scale Challenge**: Processing 100M+ images may exceed initial storage/compute estimates - **Performance**: Search response times may be slower than expected with large dataset - **Model Accuracy**: Computer vision models may not work well for all image types **Mitigation Strategies:** - Start with subset of Commons images (1M) for proof of concept - Implement caching and optimization strategies - Test multiple vision models to find best performance ### Community Risks - **Low Adoption**: Users may not discover or use the tool - **Quality Concerns**: Results may not meet community expectations - **Maintenance**: Long-term maintenance and updates may be challenging **Mitigation Strategies:** - Engage Commons community early for feedback - Implement user feedback mechanisms - Plan for sustainable maintenance model ## Success Criteria ### Phase 1 (Proof of Concept) - [ ] Working prototype with 100K Commons images indexed - [ ] Basic web interface allowing image upload and search - [ ] Search results return in <5 seconds - [ ] Positive feedback from 10+ beta testers ### Phase 2 (Full Launch) - [ ] Full Commons dataset (10M+ images) searchable - [ ] 1000+ monthly active users within first 3 months - [ ] Average search accuracy rated >3.5/5 by users - [ ] Tool mentioned positively in Commons community discussions #### 4.
