Automatically Creating a Lexicon of Verbal Polarity Shifters: Mono- and Cross-lingual Methods for German (C18-1)
Copied to clipboard
| Challenge: | a large number of verbal polarity shifters are available for multiple languages, but only English has a sizable lexicon of them. |
| Approach: | They use methods to create large lexicon of verbal polarity shifters in germany . they bootstrap annotated verbs with a supervised classifier and apply them to German . |
| Outcome: | The proposed method is able to create a large lexicon of verbal polarity shifters in germany . it reduces annotation effort by leveraging cross-lingual information from the English lexico . |
Introducing a Lexicon of Verbal Polarity Shifters for English (L18-1)
Copied to clipboard
| Challenge: | Negation words can change the sentiment polarity of a phrase, but there are more than 1200 other polarities. |
| Approach: | They propose a lexicon of verbal polarity shifters that covers the entirety of verbs found in WordNet. |
| Outcome: | The proposed lexicon covers the entirety of verbs found in WordNet. |
How to be FAIR when you CARE: The DGS Corpus as a Case Study of Open Science Resources for Minority Languages (2022.lrec-1)
Copied to clipboard
| Challenge: | a corpus of recordings of members of the deaf community in germany is published under the FAIR principles . CARE principles are used to ensure data is open and respects indigenous and minority group stakeholders. |
| Approach: | This article describes how the DGS Corpus implemented the CARE principles . the principles were introduced as a guide to good open data practices . they also help identify how openness of data should be limited or adjusted . |
| Outcome: | The DGS Corpus is a large collection of recordings of members of the deaf community in germany . the CARE principles have been used to help the corpus achieve its goals . |
ATC-ANNO: Semantic Annotation for Air Traffic Control with Assistive Auto-Annotation (2020.lrec-1)
Copied to clipboard
| Challenge: | ATC communications are a challenging domain for automatic speech recognition (ASR) due to the time-sensitive nature of their task, annotators must have prior experience with ATC communication. |
| Approach: | They propose a tool for the transcription and semantic annotation of air traffic communications. |
| Outcome: | The proposed tool can annotate four times as many utterances in a single time. |
Enhancing a Lexicon of Polarity Shifters through the Supervised Classification of Shifting Directions (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing polarity shifter lexica only specify when a word can cause shifting, but do not specify when this is limited to a single shifting direction. |
| Approach: | They propose a classifier that determines the shifting direction of polarity shifters by using resource-driven features and data-driven feature. |
| Outcome: | The proposed classifier enhances the largest available polarity shifter lexicon. |
