| Challenge: | the Common European Language Data Space (LDS) is an integral part of the EU data strategy, which aims at developing a single market for data. |
| Approach: | the Common European Language Data Space (LDS) is an integral part of the EU data strategy . its decentralised technical infrastructure and governance scheme are currently being developed by the LDS project . |
| Outcome: | the Common European Language Data Space (LDS) is an integral part of the EU data strategy, which aims at developing a single market for data. |

| Challenge: | Europe is a multilingual society, in which dozens of languages are spoken. |
| Approach: | They describe the European Language Grid, which is targeted to evolve into the primary platform and marketplace for LT in Europe by providing one umbrella platform for the European LT landscape. |
| Outcome: | The European Language Grid (ELG) will provide access to 1300 services for all European languages as well as thousands of data sets. |
Less for More: Enhanced Feedback-aligned Mixed LLMs for Molecule Caption Generation and Fine-Grained NLI Evaluation (2025.acl-long)
Copied to clipboard
| Challenge: | Recent trends have led to the use of multimodal models to learn molecular and linguistic representations, either in separate but coordinated spaces or in a common space. |
| Approach: | They propose a novel atomic-level evaluation method leveraging off-the-shelf Natural Language Inference (NLI) models for use in the unseen chemical domain. |
| Outcome: | The proposed method surpasses state-of-the-art models in the unseen chemical domain while relying on a granularity-based evaluation method. |

| Challenge: | Recent advances in LLMs enable artificial facilitation agents to not only moderate content, but also actively improve the quality of interactions. |
| Approach: | They propose a taxonomy on discussion quality evaluation and a new taxonomies for intervention and facilitation strategies. |
| Outcome: | The proposed methods synthesize ideas from Natural Language Processing (NLP) and Social Sciences to provide a taxonomy on discussion quality evaluation, and a roadmap of good practices and future research directions. |
A Digital Language Coherence Marker for Monitoring Dementia (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies have shown that dementia is associated with thought disorders relating to inability to produce coherent communication. |
| Approach: | They propose to capture language coherence as a human-interpretable digital marker for monitoring cognitive changes in people with dementia. |
| Outcome: | The proposed model shows a significant difference between people with mild cognitive impairment, those with Alzheimer’s Disease and healthy controls and high association with clinical bio-markers. |
Reformulating NLP tasks to Capture Longitudinal Manifestation of Language Disorders in People with Dementia. (2023.emnlp-main)
Copied to clipboard
| Challenge: | Dementia is associated with language disorders which impede communication. |
| Approach: | They propose to use a pre-trained language model to automatically learn linguistic disorder patterns by forcing it to focus on reformulated natural language processing (NLP) tasks and associated linguistic patterns. |
| Outcome: | The proposed communication marker outperforms existing linguistic approaches and shows external validity via significant correlation with clinical markers of behaviour. |
