Comparing Constraints for Taxonomic Organization (N18-1)
Copied to clipboard
| Challenge: | Using general ontologies and domain-specific ontology, taxonomies encode knowledge that is important for understanding systems. |
| Approach: | They propose to modify a non-transitive branching algorithm to explicitly incorporate synonymy into the taxonomy structure to give it a faster performance. |
| Outcome: | The proposed method outperforms the best transitive algorithm while giving comparable performance over a dataset of local taxonomies. |
Learning Scalar Adjective Intensity from Paraphrases (D18-1)

| Challenge: | Existing lexical resources do not include the relative intensities of adjectives. |
| Approach: | They propose a method to automatically learn relative intensity relation between scalar adjectives . they use a paraphrase-based method that assumes that a pair of adjectives is "really hot" a similar method is used to infer the polarity of indirect answers to "yes/no" questions . |
| Outcome: | The proposed method improves the quality of systems for ordering sets of scalar adjectives and inferring the polarity of indirect answers to "yes/no" questions. |
Automated Paraphrase Lattice Creation for HyTER Machine Translation Evaluation (N18-2)
Copied to clipboard
| Challenge: | Existing machine translation evaluation metrics use synonyms and paraphrases to reward meaning-equivalent but lexically divergent translations. |
| Approach: | They propose a machine translation evaluation metric which exploits reference translations enriched with meaning equivalent expressions. |
| Outcome: | The proposed metric achieves medium performance on large and noisier datasets . it is compared with the existing HyTER evaluation metric . |
