Universal Grammatical Dependencies for Portuguese with CINTIL Data, LX Processing and CLARIN support (2022.lrec-1)
Copied to clipboard
| Challenge: | a new collection of quality language resources is presented for the computational processing of the Portuguese language . the framework for the mapping between linguistic form and meaning is centered on the notion of grammatical relation . |
| Approach: | They propose a new set of quality language resources for the computational processing of the Portuguese language under the Universal Dependencies framework. |
| Outcome: | The proposed framework provides for the mapping between linguistic form and meaning representations. |

| Challenge: | Scientific knowledge is grounded on falsifiable predictions and therefore its credibility and raison d'être rely on the possibility of repeating experiments and getting similar results as originally obtained and reported. |
| Approach: | They propose a collaborative task which is collaborative rather than competitive and supports reproduction of research results. |
| Outcome: | The proposed task is called REPROLANG-The Shared Task on the Reproduction of Research Results in Science and Technology of Natural Language Processing (LREC2020). |
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. |
Reproduction and Revival of the Argument Reasoning Comprehension Task (2020.lrec-1)
Copied to clipboard
| Challenge: | Reproduction of scientific results is essential for scientific development across all disciplines. |
| Approach: | They evaluate scientific reproduction of arguments reasoning comprehension systems . they find reproducing results of previous work is a basic requirement for validating hypothesis . |
| Outcome: | The proposed systems were compared with the revised data set and scored in line with the results of the argument reasoning comprehension task. |
Shortcutted Commonsense: Data Spuriousness in Deep Learning of Commonsense Reasoning (2021.emnlp-main)
Copied to clipboard
| Challenge: | a recent study has found that commonsense reasoning models are learning transferable generalizations . commonsensibility is a human capacity that has been a core challenge to Artificial Intelligence since its inception. |
| Approach: | They conduct an analysis of benchmarks that involve commonsense reasoning . they find that most datasets experimented with are problematic . commonsensence is a quintessential human capacity . |
| Outcome: | The proposed model is able to perform well on commonsense reasoning tasks . the model is not learning transferable generalizations or taking advantage of shortcuts . |

Copied to clipboard
| Challenge: | a new corpus of literary documents in Portuguese is presented . it includes close to 4 million words from over 200 complete documents . the corpus is suitable for research in language technology and digital humanities . |
| Approach: | They present the BDCames Collection of Portuguese Literary Documents, a new corpus of literary texts written in Portuguese. |
| Outcome: | The BDCames Collection of Portuguese Literary Documents is a new corpus of literary documents written in Portuguese . it includes close to 4 million words from over 200 complete documents from 83 authors in 14 genres . the corpus is suitable for research in language technology and language science and digital humanities . |

| 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. |
