Situation
Legal practitioners needed fast, reliable briefs from long judgments, but typical AI summaries can hallucinate facts or repeat themselves—making outputs hard to trust.
Task
Build a system that produces concise case briefs while proving where each key fact came from and minimizing repetition, focusing on Zimbabwean High Court and Supreme Court judgments.
Action
- Implemented a hybrid summarization pipeline: extract key sentences, then generate a coherent brief from the extracted content.
- Added similarity-based redundancy filtering to prevent repeated statements in the final summary.
- Introduced explainability by linking key statements back to source paragraph indices for verification.
Result
- Delivered verifiable summaries where users can trace claims back to the judgment text.
- Reduced hallucination risk by grounding generation in extracted source sentences.
- Improved readability by removing repetitive content for cleaner briefs.
