Right for the Wrong Reasons: Diagnosing Syntactic Heuristics in Natural Language Inference (P19-1)
Copied to clipboard
| Challenge: | lexical overlap heuristics are effective for frequent example types but break down in more challenging cases. |
| Approach: | They propose to use a set of examples to test whether a sentence entails another . they propose to adopt three fallible syntactic heuristics for statistical NLI models . |
| Outcome: | The proposed model performs poorly on the HANS dataset, suggesting they have adopted these heuristics. |

| Challenge: | morphological parsers for two Afroasiatic languages are developed using a parser-combinator paradigm . the paradigm allows rapid development and ease of integration with other systems, but at a cost of non-optimal theoretical efficiency. |
| Approach: | They propose a rule-based morphological parser paradigm for Tigrinya and Oromo languages . they use a parsers-combinator paradigm instead of a finite-state paradigm . |
| Outcome: | The proposed paradigm allows rapid development and ease of integration with other systems, but at cost of non-optimal theoretical efficiency. |
