A Syntax-Aware Edit-based System for Text Simplification

no code implementations RANLP 2021 Oscar M. Cumbicus-Pineda, Itziar Gonzalez-Dios, Aitor Soroa

Edit-based text simplification systems have attained much attention in recent years due to their ability to produce simplification solutions that are interpretable, as well as requiring less training examples compared to traditional seq2seq systems.

Text Simplification

Principled Paraphrase Generation with Parallel Corpora

1 code implementation ACL 2022 Aitor Ormazabal, Mikel Artetxe, Aitor Soroa, Gorka Labaka, Eneko Agirre

Round-trip Machine Translation (MT) is a popular choice for paraphrase generation, which leverages readily available parallel corpora for supervision.

Ontology Population Reusing Resources for Dialogue Intent Detection: Generic and Multilingual Approach

no code implementations RANLP 2021 Cristina Aceta, Izaskun Fernández, Aitor Soroa

This work presents a generic semi-automatic strategy to populate the domain ontology of an ontology-driven task-oriented dialogue system, with the aim of performing successful intent detection in the dialogue process, reusing already existing multilingual resources.

Does Corpus Quality Really Matter for Low-Resource Languages?

no code implementations15 Mar 2022 Mikel Artetxe, Itziar Aldabe, Rodrigo Agerri, Olatz Perez-de-Viñaspre, Aitor Soroa

The vast majority of non-English corpora are derived from automatically filtered versions of CommonCrawl.

Image Captioning for Effective Use of Language Models in Knowledge-Based Visual Question Answering

1 code implementation15 Sep 2021 Ander Salaberria, Gorka Azkune, Oier Lopez de Lacalle, Aitor Soroa, Eneko Agirre

Our results on a visual question answering task which requires external knowledge (OK-VQA) show that our text-only model outperforms pretrained multimodal (image-text) models of comparable number of parameters.

Improving Conversational Question Answering Systems after Deployment using Feedback-Weighted Learning

1 code implementation COLING 2020 Jon Ander Campos, Kyunghyun Cho, Arantxa Otegi, Aitor Soroa, Gorka Azkune, Eneko Agirre

The interaction of conversational systems with users poses an exciting opportunity for improving them after deployment, but little evidence has been provided of its feasibility.

Conversational Question Answering in Low Resource Scenarios: A Dataset and Case Study for Basque

no code implementations LREC 2020 Arantxa Otegi, Aitor Agirre, Jon Ander Campos, Aitor Soroa, Eneko Agirre

Conversational Question Answering (CQA) systems meet user information needs by having conversations with them, where answers to the questions are retrieved from text.

Evaluating Multimodal Representations on Visual Semantic Textual Similarity

1 code implementation4 Apr 2020 Oier Lopez de Lacalle, Ander Salaberria, Aitor Soroa, Gorka Azkune, Eneko Agirre

In the case of textual representations, inference tasks such as Textual Entailment and Semantic Textual Similarity have been often used to benchmark the quality of textual representations.

Analyzing the Limitations of Cross-lingual Word Embedding Mappings

no code implementations ACL 2019 Aitor Ormazabal, Mikel Artetxe, Gorka Labaka, Aitor Soroa, Eneko Agirre

Recent research in cross-lingual word embeddings has almost exclusively focused on offline methods, which independently train word embeddings in different languages and map them to a shared space through linear transformations.

Interoperability of Annotation Schemes: Using the Pepper Framework to Display AWA Documents in the ANNIS Interface

no code implementations LREC 2016 Talvany Carlotto, Zuhaitz Beloki, Xabier Artola, Aitor Soroa

That is often caused by the different linguistic formats used across the applications, which leads to attempts to both establish standard formats to represent linguistic information and to create conversion tools to facilitate this integration.

Two Architectures for Parallel Processing of Huge Amounts of Text

no code implementations LREC 2016 Mathijs Kattenberg, Zuhaitz Beloki, Aitor Soroa, Xabier Artola, Antske Fokkens, Paul Huygen, Kees Verstoep

This paper presents two alternative NLP architectures to analyze massive amounts of documents, using parallel processing.

Improving distant supervision using inference learning

no code implementations IJCNLP 2015 Roland Roller, Eneko Agirre, Aitor Soroa, Mark Stevenson

Distant supervision is a widely applied approach to automatic training of relation extraction systems and has the advantage that it can generate large amounts of labelled data with minimal effort.
