Improving Hypernymy Extraction with Distributional Semantic Classes (L18-1)
Copied to clipboard
| Challenge: | Existing methods for extracting hypernyms focus on the acquisition of binary hypernies . |
| Approach: | They propose a distributionally-induced semantic class for extracting hypernyms . they also use distributional semantics to induce sense-aware semantic classes . |
| Outcome: | The proposed method improves the quality of the hypernymy extraction in terms of precision and recall. |
Generalized Tuning of Distributional Word Vectors for Monolingual and Cross-Lingual Lexical Entailment (P19-1)
Copied to clipboard
| Challenge: | Lexical entailment (LE) is a core asymmetric lexical relation that supports tasks like taxonomy induction and text generation. |
| Approach: | They propose a generalized Lexical ENtailment model that captures a specialization function allowing for LE-tuning of the entire distributional vector space and not only the vectors of words seen in lexical constraints. |
| Outcome: | The proposed model improves on graded LE and shows 20% improvement over state-of-the-art LE detection. |
