Claims

C1strongest claim

We present the BenGER (Benchmark for German Law) framework, an open-source web platform that integrates task creation, collaborative annotation, configurable LLM runs, and evaluation with lexical, semantic, factual, and judge-based metrics. BenGER supports multi-organization projects with tenant isolation and role-based access control, and can optionally provide formative, reference-grounded feedback to annotators.

C2weakest assumption

That integrating task design, annotation, LLM execution, and multi-metric evaluation into a single web platform with tenant isolation and role-based access will meaningfully improve transparency, reproducibility, and participation by non-technical legal experts compared to existing split workflows.

C3one line summary

BenGER is a collaborative web platform that integrates end-to-end workflows for creating, annotating, running, and evaluating benchmarks on German legal tasks with large language models.
