Information Extraction and Information Retrieval
The ever increasing availability of unstructured textual resources in the Web and their potential to be used in applications for the automatic acquisition of knowledge have caused a dramatic rise in research related to Information Extraction (IE) and Information Retrieval (IR). Traditionally, the required textual content was produced by means of manual annotations by human experts on the task at hand, which is too costly in terms of both economic and human resources. In the last decade, new t...Read More

A modular approach for multilingual timex detection and normalization using deep learning and grammar-based methods (2023)
Nayla Escribano, German Rigau, Rodrigo Agerri, A modular approach for multilingual timex detection and normalization using deep learning and grammar-based methods, Knowledge-Based Systems, Volume 273, 2023, 110612, ISSN 0950-7051, https://doi.org/10.1016/j.knosys.2023.110612. (https://www.sciencedirect.com/science/article/pii/S0950705123003623) Abstract: Detecting and normalizing temporal expressions is an essential step for many NLP tasks. While a variety of methods have been proposed for detection, best normalization approaches rely on hand-crafted rules. Furthermore, most of them have been designed only for English. In this paper we present a modular multilingual temporal processing system combining a fine-tuned Masked Language Model for detection, and a grammar-based normalizer. We experiment in Spanish and English and compare with HeidelTime, the state-of-the-art in multilingual temporal processing. We obtain best results in gold timex normalization, timex detection and type recognition, and competitive performance in the combined TempEval-3 relaxed value metric. A detailed error analysis shows that detecting only those timexes for which it is feasible to provide a normalization is highly beneficial in this last metric. This raises the question of which is the best strategy for timex processing, namely, leaving undetected those timexes for which is not easy to provide normalization rules or aiming for high coverage.

A modular approach for multilingual timex detection and normalization using deep learning and grammar-based methods (2023)
Nayla Escribano, German Rigau, Rodrigo Agerri, A modular approach for multilingual timex detection and normalization using deep learning and grammar-based methods, Knowledge-Based Systems, Volume 273, 2023, 110612, ISSN 0950-7051, https://doi.org/10.1016/j.knosys.2023.110612. (https://www.sciencedirect.com/science/article/pii/S0950705123003623) Abstract: Detecting and normalizing temporal expressions is an essential step for many NLP tasks. While a variety of methods have been proposed for detection, best normalization approaches rely on hand-crafted rules. Furthermore, most of them have been designed only for English. In this paper we present a modular multilingual temporal processing system combining a fine-tuned Masked Language Model for detection, and a grammar-based normalizer. We experiment in Spanish and English and compare with HeidelTime, the state-of-the-art in multilingual temporal processing. We obtain best results in gold timex normalization, timex detection and type recognition, and competitive performance in the combined TempEval-3 relaxed value metric. A detailed error analysis shows that detecting only those timexes for which it is feasible to provide a normalization is highly beneficial in this last metric. This raises the question of which is the best strategy for timex processing, namely, leaving undetected those timexes for which is not easy to provide normalization rules or aiming for high coverage.
