Lexical Substitution for Evaluating Compositional Distributional Models (N18-2)
Copied to clipboard
| Challenge: | Compositional Distributional Semantic Models (CDSMs) model the meaning of phrases and sentences in vector space. |
| Approach: | They propose to use lexical substitution to evaluate CDSMs by comparing a LexSub-annotated corpus with a manual LexSub annotation. |
| Outcome: | The proposed model outperforms simple component-wise CDSMs and performs on par with the context2vec LexSub model using the same context. |
A Tale of Three Parsers: Towards Diagnostic Evaluation for Meaning Representation Parsing (2020.lrec-1)
Copied to clipboard
| Challenge: | Empirical results suggest that the proposed methodology can be meaningfully applied to parsing into graph-structured target representations, uncovering hitherto unknown properties of the different approaches. |
| Approach: | They propose to map from natural language utterances to graph-based encodings of its semantic structure using contrastive and diagnostic evaluation techniques. |
| Outcome: | The proposed method can be meaningfully applied to parsing into graph-structured target representations, uncovering hitherto unknown properties of the different systems that can inform future development and cross-fertilization across approaches. |
