Copied to clipboard
| Challenge: | a newly published Danish sentiment lexicon with a high lexical coverage was compiled using lexicographic methods and linked data. |
| Approach: | They propose to use lexicographic methods to compile a Danish sentiment lexicon with a high lexical coverage by linking words from a thesaurus to a comprehensive monolingual dictionary. |
| Outcome: | The proposed lexicon contains 13,859 Danish polarity lemmas and includes morphological information. |

| Challenge: | Language Technologies (LTs) are a powerful means to break down language barriers impacting business, cross-lingual and cross-cultural communication in Europe. |
| Approach: | They present an overview of the European LT landscape and the current state of play in industry and the LT market. |
| Outcome: | The present study outlines funding programmes, activities, actions and challenges in the different countries with regard to LT, including the current state of play in industry and the LT market. |

| Challenge: | The central word register for Danish is an open source lexicon project for general AI purposes funded and initiated by the Danish Agency for Digitisation in 2020. |
| Approach: | They propose to use existing fine-grained sense inventory to compile a more AI-appropriate sense granularity level of the vocabulary. |
| Outcome: | The proposed lexical resource is based on the fine-grained sense inventory from Den Danske Ordbog (DDO) it is designed to be more practical and suitable for AI, omitting outdated language and slang, merging subtle and rare sub-senses with their main sense, disregarding sub-domains, etc. |
A Danish FrameNet Lexicon and an Annotated Corpus Used for Training and Evaluating a Semantic Frame Classifier (L18-1)
Copied to clipboard
| Challenge: | a Danish FrameNet is a lexicon based on the Danish Thesaurus . it is significantly faster than building a new one from scratch . |
| Approach: | They propose a way to efficiently compile a Danish FrameNet based on the Danish Thesaurus . they present the corresponding corpus annotations of frames and roles and show how this can be used for a semantic frame classifier . |
| Outcome: | The proposed approach is faster than building a lexicon from scratch. |
World Class Language Technology - Developing a Language Technology Strategy for Danish (2020.lrec-1)
Copied to clipboard
| Challenge: | Danish government adopts ambitious strategy for LT and artificial intelligence . 35 million DKK will be spent over a period of 6 years to develop platform . |
| Approach: | They describe the process behind the development of the language-related parts of the strategy . they describe how focus areas and recommendations for the LT strategy were established . |
| Outcome: | The Danish government adopted a new, ambitious strategy for LT and AI in March 2019 . the focus areas and recommendations for the LT strategy were established based on user feedback . |

| Challenge: | a new dataset aims to align monolingual dictionaries with a single sense level for 15 languages . this dataset covers a wide range of languages and resources . |
| Approach: | They propose to manually align monolingual dictionaries with possible semantic relationships . they use 15 languages to create a new baseline for the task of monolingual word sense alignment . |
| Outcome: | The proposed dataset covers 15 languages and covers the more challenging task of linking general-purpose language. |
Probing for Hyperbole in Pre-Trained Language Models (2023.acl-srw)
Copied to clipboard
| Challenge: | Hyperbole is a common figure of speech that involves the use of exaggerated language for emphasis or effect. |
| Approach: | They conduct edge and minimal description length probing experiments on three pre-trained language models to explore the extent to which hyperbolic information is encoded . they also annotate 63 hyperbole sentences from the HYPO dataset according to an operational taxonomy to conduct an error analysis to explore encoding of different hyperboli categories. |
| Outcome: | The results show that hyperbole is encoded in a limited extent in pre-trained models and mostly in the final layers. |
Towards a Gold Standard for Evaluating Danish Word Embeddings (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing word embedding models resemble semantic similarity solely by distribution, but there seems to be a need for future judgments to measure similarity in full context and along more than a single spectrum. |
| Approach: | They propose a model-agnostic similarity goal standard for evaluating Danish word embeddings based on human judgments made by 42 native speakers of Danish. |
| Outcome: | The goal standard is applied to evaluate Danish word embeddings on 42 native speakers of Danish. |
Towards a Danish Semantic Reasoning Benchmark - Compiled from Lexical-Semantic Resources for Assessing Selected Language Understanding Capabilities of Large Language Models (2024.lrec-main)
Copied to clipboard
| Challenge: | a semantic reasoning benchmark for Danish is compiled from human-curated lexical-semantic resources. |
| Approach: | They present a semantic reasoning benchmark for Danish compiled semi-automatically from a number of human-curated lexical-semantic resources. |
| Outcome: | The proposed datasets are compiled semi-automatically from human-curated lexical-semantic resources. |

| Challenge: | euphemisms are a linguistic device used to soften discussions of uncomfortable topics . euphorias are used to refer to death in a less direct manner during a period of secularization . |
| Approach: | They propose to use a corpus of Danish and Norwegian novels to detect death-related euphemisms . they use pre-trained language models to detect euphoric and literal references to death . |
| Outcome: | The proposed method improves on state-of-the-art language models. |
