Semantic Equivalence Detection: Are Interrogatives Harder than Declaratives? (L18-1)
Copied to clipboard
| Challenge: | Semantic Text Similarity (STS) tasks are often not seen as similar to semantic equivalence detection tasks. |
| Approach: | They propose to assess the performance of different approaches to STS over different types of textual segments. |
| Outcome: | The proposed methods differ in performance over different types of textual segments, including declaratives and interrogatives, under conditions of comparability. |
Browsing and Supporting Pluricentric Global Wordnet, or just your Wordnet of Interest (L18-1)
Copied to clipboard
| Challenge: | a wordnet browser that allows to consult wordnet content is presented in this paper . the paper presents a browser that meets design requirements and complies with the most ample range of design features. |
| Approach: | They propose a wordnet browser that meets design requirements for wordnets . they use existing browsers to analyze their functionalities and build a new browser . |
| Outcome: | The proposed browser meets design requirements and complies with the most ample range of design features. |
Large Scale Author Obfuscation Using Siamese Variational Auto-Encoder: The SiamAO System (2020.starsem-1)
Copied to clipboard
| Challenge: | Existing approaches to author obfuscation are largely heuristic, but they can be used to attack author identification. |
| Approach: | They propose a deep learning architecture for constructing adversarial examples against similarity-based learners and explore its application to author obfuscation. |
| Outcome: | The proposed architectures show that they can be used to attack author obfuscation . the proposed architecture shows that it can be applied to obliquacy of text . |
Comparative Probing of Lexical Semantics Theories for Cognitive Plausibility and Technological Usefulness (2020.coling-main)
Copied to clipboard
| Challenge: | lexical semantics theories advocate that the meaning of words is represented as an inference graph, a feature mapping or a cooccurrence vector. |
| Approach: | They propose to probe different lexical semantics theories for their levels of cognitive plausibility and technological usefulness. |
| Outcome: | The proposed approach is superior to the other approaches, the authors argue . they show that the feature-based approach is more useful and more plausible than the other ones . |

| Challenge: | Lexical semantic networks are pervasive in natural language processing . Lexical ontologies play a key role in virtually all major applications . |
| Approach: | The present paper presents the MWN.PT WordNet for Portuguese . it is the largest high quality, manually validated and cross-lingually integrated wordnet of Portuguese based on the Princeton WordNet of English . |
| Outcome: | The MWN.PT WordNet for Portuguese includes 41,000 concepts expressed by 38,000 lexical units. |
