SemJoin: Semantic Join Optimization

What it contributes

Uses an LLM advisor to route joins between clustering-based candidate pruning and classification into a shared label space.

How to read the evidence

Short preprint evaluated on three datasets; routing success on those workloads does not establish universal optimality.

We checked the primary publication record and abstract. This profile summarizes author-reported work; it does not claim a full-paper audit, implementation audit, or independent reproduction.
