- In the realm of entity linking and data enrichment, having a robust backend algorithm is only half the battle. Equally critical is the ability to visualize and interact with the results efficiently. Enter KOALA-UI, a modern front-end application designed by SINTEF to complement powerful entity linking algorithms like Crocodile while setting the stage for future integrations.
Why KOALA-UI Matters
Entity linking often involves working with large, complex datasets that require both automation and human oversight. Traditional tools struggle with:
- Scalability: Handling thousands of records without performance bottlenecks.
- Usability: Simplifying complex workflows for non-technical users.
- Flexibility: Supporting diverse backends and entity linking algorithms.
KOALA-UI addresses these challenges by offering an intuitive, interactive interface that combines automation with human-in-the-loop verification, ensuring high-quality results for downstream tasks like analytics and decision-making.
Key Features of KOALA-UI
- Interactive Visualization
KOALA-UI provides real-time visual feedback on entity linking results, including confidence scores, unresolved entities, and enriched metadata. The clean, tabular design ensures users can quickly interpret and act on the data.

- Human-in-the-Loop Verification
Balancing automation with human expertise, KOALA-UI allows users to review and confirm entity matches or make corrections when necessary. This ensures the system continuously learns from user feedback, improving accuracy over time.

- Scalability for Large Datasets
Optimized for handling thousands of records, KOALA-UI employs techniques like efficient memory management to maintain responsiveness, even with industrial-scale datasets.
- Customizable Filters and Search
Users can apply advanced filters to refine their search based on entity types or confidence scores, enabling precise control over the data enrichment process.

- Future-Proof Design
While currently integrated with Crocodile, KOALA-UI is built to support any backend entity linking algorithm via a consistent API format. This makes it a versatile tool for evolving data enrichment needs.
How KOALA-UI Works
- Dataset Loading: Users upload datasets into the system via a simple interface. Columns are automatically classified as Named Entities (NE) or Literals (LIT).
- Entity Linking in Action: The backend algorithm – Crocodile processes the data, returning enriched tables with linked entities and confidence scores.
- User Interaction: Users review results in real-time through the interactive table view, leveraging filters and semantic details to refine matches as needed.
- Export Enriched Data: Once verified, the enriched dataset can be exported for further analysis or integration into downstream applications.
