Papers by Pere-Lluís Huguet Cabot
Us vs. Them: A Dataset of Populist Attitudes, News Bias and Emotions (2021.eacl-main)
Copied to clipboard
| Challenge: | Populist rhetoric has risen across the political sphere in recent years, but computational approaches to it have been scarce. |
| Approach: | They propose a dataset of 6861 reddit comments annotated for populist attitudes and a set of multi-task learning models that leverage emotion and group identification as auxiliary tasks. |
| Outcome: | The proposed models leverage emotion and group identification as auxiliary tasks to model populist rhetoric tasks. |
BOOKCOREF: Coreference Resolution at Book Scale (2025.acl-long)
Copied to clipboard
| Challenge: | Existing benchmarks for coreference resolution systems are limited in length and do not adequately assess system capabilities at the book scale. |
| Approach: | They propose a novel pipeline that produces high-quality coreference resolution annotations on full narrative texts and a book-scale benchmark, BOOKCOREF. |
| Outcome: | The proposed pipeline produces high-quality coreference resolution annotations on full texts with an average document length of more than 200,000 tokens. |
Beyond Correlation: Interpretable Evaluation of Machine Translation Metrics (2024.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have shown that MT metrics return assessments as scalar scores that are difficult to interpret, posing a challenge to making informed design choices. |
| Approach: | They propose an interpretable evaluation framework that evaluates MT metrics in two scenarios that serve as proxies for filtering and translation re-ranking use cases. |
| Outcome: | The proposed framework offers clearer insights than correlation with human judgments. |
RAED: Retrieval-Augmented Entity Description Generation for Emerging Entity Linking and Disambiguation (2025.emnlp-main)
Copied to clipboard
| Challenge: | Entity Linking and Entity Disambiguation systems assume static knowledge bases are incomplete and up-to-date, rendering them incapable of handling entities not yet included in the knowledge base. |
| Approach: | They propose a model that retrieves external knowledge to improve factual grounding in entity descriptions. |
| Outcome: | The proposed model outperforms systems that require fixed knowledge sets on Entity Disambiguation and Wikipedia to improve factual grounding in entity descriptions. |
REBEL: Relation Extraction By End-to-end Language generation (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to extract relation triplets from text often involve multiple-step pipelines that propagate errors or are limited to a small number of relation types. |
| Approach: | They propose to use autoregressive seq2seq models to simplify Relation Extraction by expressing triplets as a sequence of text and a model that performs end-to-end relation extraction for more than 200 different relation types. |
| Outcome: | The proposed model achieves state-of-the-art on an array of Relation Extraction and Relation Classification benchmarks and achieves top performance in most of them. |

| Challenge: | Existing approaches to integrate semantics into Natural Language Understanding (NLP) systems are cost-effective and environmental impact-related. |
| Approach: | They propose to provide semantically-annotated corpora for four NLU tasks across five languages and to drop the requirement of closed datasets. |
| Outcome: | The proposed model provides hundreds of millions of silver yet high-quality annotations for four NLU tasks across five languages. |
ReLiK: Retrieve and LinK, Fast and Accurate Entity Linking and Relation Extraction on an Academic Budget (2024.findings-acl)
Copied to clipboard
| Challenge: | Entity Linking and Relation Extraction (EL) are fundamental tasks in Natural Language Processing. |
| Approach: | They propose a Retriever-Reader architecture for Entity Linking and Relation Extraction . they propose an input representation that incorporates the candidate entities alongside the text . |
| Outcome: | The proposed architecture achieves state-of-the-art in in- and out-of domain benchmarks while using academic budget training and with 40x inference speed compared to competitors. |

| Challenge: | Large Language Models (LLMs) have advanced significantly in understanding human text, but semantic representations remain crucial for various applications. |
| Approach: | They introduce a multilingual semantic layer which decouples from disambiguation and external inventories and simplifies the task. |
| Outcome: | The proposed model reduces performance gap between languages and annotators by enabling them to understand semantic relations between concepts in any language. |
The Pragmatics behind Politics: Modelling Metaphor, Framing and Emotion in Political Discourse (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing computational models of political discourse do not incorporate metaphor and emotion in their functions. |
| Approach: | They propose to combine metaphor, emotion and political rhetoric to model political discourse . they show that they advance in three tasks: predicting political perspective of news articles, party affiliation of politicians and framing of policy issues. |
| Outcome: | The proposed models improve political discourse prediction, party affiliation and framing of policy issues. |
Optimizing LLMs for Italian: Reducing Token Fertility and Enhancing Efficiency Through Vocabulary Adaptation (2025.findings-naacl)

| Challenge: | Pretrained Large Language Models (LLMs) are mainly designed for the English language, but are not optimized for non-English languages due to language contamination or multilingual pretraining data. |
| Approach: | They propose a method that leverages neural mapping for vocabulary substitution to optimize LLMs for the Italian language. |
| Outcome: | The proposed method reduces token fertility by 25% and improves grounded alignment strategies. |
