# LCWAEvaluationLoop¶

Bases: EvaluationLoop[Mapping[Literal[‘head’, ‘relation’, ‘tail’], LongTensor]]
For brevity, we only describe evaluation for tail prediction. Let $$(h, r, t) \in \mathcal{T}_{eval}$$ denote an evaluation triple. Then, we calculate scores for all triples $$(h, r, t')$$ with $$t' \in \mathcal{E}$$, i.e., for replacing the true tail $$t$$ by all entities.
