It keeps the matching of predicates and role fillers, but changes how two fillers are compared: an idf-weighted distributional n-gram accuracy, computed from word embeddings trained on a monolingual corpus of the output… 3. **[MEANT: An inexpensive, high-accuracy, semi-automatic metric for evaluating translation utility based on semantic roles](https://md.research.elamur.ai/free/en/papers/lo-2011-meant-inexpensive-high-accuracy-semi/)** *(2011)* MEANT judges translation utility, meaning whether a reader can recover who did what to whom. For each predicate in the reference and in the output it aligns predicates by lexical similarity, aligns the role fillers of each aligned pair by weighted bipartite matching, and computes a weighted F-score over the matched… ## Co-authors (10) - [Alon Lavie](https://md.research.elamur.ai/free/en/authors/alon-lavie/) - André F.
