Textual Entailment for Effective Triple Validation in Object Prediction
Andrés García-Silva, Cristian Berrío, José Manuel Gómez-Pérez
Knowledge base population seeks to expand knowledge graphs with facts that are typically extracted from a text corpus. Recently, language models pretrained on large corpora have be…
Capturing Pertinent Symbolic Features for Enhanced Content-Based Misinformation Detection
Flavio Merenda, José Manuel Gómez-Pérez
Preventing the spread of misinformation is challenging. The detection of misleading content presents a significant hurdle due to its extreme linguistic and domain variability. Cont…
SpaceQA: Answering Questions about the Design of Space Missions and Space Craft Concepts
Andrés García-Silva, Cristian Berrío, José Manuel Gómez-Pérez +3
We present SpaceQA, to the best of our knowledge the first open-domain QA system in Space mission design. SpaceQA is part of an initiative by the European Space Agency (ESA) to fac…
On the Impact of Knowledge-based Linguistic Annotations in the Quality of Scientific Embeddings
Andres Garcia-Silva, Ronald Denaux, Jose Manuel Gomez-Perez
In essence, embedding algorithms work by optimizing the distance between a word and its usual context in order to generate an embedding space that encodes the distributional repres…
Understanding Transformers for Bot Detection in Twitter
Andres Garcia-Silva, Cristian Berrio, Jose Manuel Gomez-Perez
In this paper we shed light on the impact of fine-tuning over social media data in the internal representations of neural language models. We focus on bot detection in Twitter, a k…
Classifying Scientific Publications with BERT -- Is Self-Attention a Feature Selection Method?
Andres Garcia-Silva, Jose Manuel Gomez-Perez
We investigate the self-attention mechanism of BERT in a fine-tuning scenario for the classification of scientific articles over a taxonomy of research disciplines. We observe how…
ISAAQ -- Mastering Textbook Questions with Pre-trained Transformers and Bottom-Up and Top-Down Attention
Jose Manuel Gomez-Perez, Raul Ortega
Textbook Question Answering is a complex task in the intersection of Machine Comprehension and Visual Question Answering that requires reasoning with multimodal information from te…
Linked Credibility Reviews for Explainable Misinformation Detection
Ronald Denaux, Jose Manuel Gomez-Perez
In recent years, misinformation on the Web has become increasingly rampant. The research community has responded by proposing systems and challenges, which are beginning to be usef…
Assessing the Lexico-Semantic Relational Knowledge Captured by Word and Concept Embeddings
Ronald Denaux, Jose Manuel Gomez-Perez
Deep learning currently dominates the benchmarks for various NLP tasks and, at the basis of such systems, words are frequently represented as embeddings --vectors in a low dimensio…
Enabling FAIR Research in Earth Science through Research Objects
Andres Garcia-Silva, Jose Manuel Gomez-Perez, Raul Palma +24
Data-intensive science communities are progressively adopting FAIR practices that enhance the visibility of scientific breakthroughs and enable reuse. At the core of this movement,…
Not just about size - A Study on the Role of Distributed Word Representations in the Analysis of Scientific Publications
Andres Garcia, Jose Manuel Gomez-Perez
The emergence of knowledge graphs in the scholarly communication domain and recent advances in artificial intelligence and natural language processing bring us closer to a scenario…
