    L’objectiu d’aquest treball és l’anàlisi d’errors continguts en un corpus d’informes mèdics en llenguatge natural i el disseny d’una tipologia d’errors, ja que no hi va haver una revisió sistemàtica sobre verificació i correcció d’errors en documentació clínica en castellà. En el desenvolupament de sistemes automàtics de detecció i correcció, és d’interès aprofundir en la naturalesa dels errors lingüístics que es produeixen en els informes clínics per tal de detectar-los i tractar-los adequadament. Els resultats mostren que els errors d’omissió són els més freqüents en la mostra analitzada i que la longitud de la paraula sens dubte influeix en la freqüència d’error. La tipificació dels patrons d’error proporcionats permet el desenvolupament d’un mòdul basat en coneixements lingüístics, actualment en curs, que serà capaç de millorar el rendiment dels sistemes de correcció de detecció i correcció d’errors per al domini biomèdicThe objective of this work is the analysis of errors contained in a corpus of medical reports in natural language and the design of a typology of errors, as there was no systematic review on verification and correction of errors in clinical documentation in Spanish. In the development of automatic detection and correction systems, it is of great interest to delve into the nature of the linguistic errors that occur in clinical reports, in order to detect and treat them properly. The results show that omission errors are the most frequent ones in the analyzed sample, and that word length certainly influences error frequency. The typification of error patterns provided is enabling the development of a module based on linguistic knowledge, which is currently in progress. This will help to improve the performance of error detection and correction systems for the biomedical domain.This work was supported by the Spanish National Research Agency (AEI) through project LaTe4PSP (PID2019-107652RB-I00/AEI/10.13039/501100011033).

    Psychographic Traits Identification based on political ideology: An author analysis study on spanish politicians tweets posted in 2020

    Get PDF
    In general, people are usually more reluctant to follow advice and directions from politicians who do not have their ideology. In extreme cases, people can be heavily biased in favour of a political party at the same time that they are in sharp disagreement with others, which may lead to irrational decision making and can put people’s lives at risk by ignoring certain recommendations from the authorities. Therefore, considering political ideology as a psychographic trait can improve political micro-targeting by helping public authorities and local governments to adopt better communication policies during crises. In this work, we explore the reliability of determining psychographic traits concerning political ideology. Our contribution is twofold. On the one hand, we release the PoliCorpus-2020, a dataset composed by Spanish politicians’ tweets posted in 2020. On the other hand, we conduct two authorship analysis tasks with the aforementioned dataset: an author profiling task to extract demographic and psychographic traits, and an authorship attribution task to determine the author of an anonymous text in the political domain. Both experiments are evaluated with several neural network architectures grounded on explainable linguistic features, statistical features, and state-of-the-art transformers. In addition, we test whether the neural network models can be transferred to detect the political ideology of citizens. Our results indicate that the linguistic features are good indicators for identifying finegrained political affiliation, they boost the performance of neural network models when combined with embedding-based features, and they preserve relevant information when the models are tested with ordinary citizens. Besides, we found that lexical and morphosyntactic features are more effective on author profiling, whereas stylometric features are more effective in authorship attribution.publishedVersio

    [SPA] La adquisición de competencias transversales es fundamental para el desarrollo de las competencias profesionales que buscan fomentar los nuevos planes de estudios desarrollados en los últimos años. En esta comunicación presentamos el enfoque docente seguido para fomentar la adquisición de estas competencias tales como la comunicación oral, el trabajo en equipo, la búsqueda de recursos en Internet y las capacidades de análisis y síntesis. El enfoque se basa en el desarrollo de unas presentaciones grupales que fueron evaluadas de manera formal de acuerdo a unos criterios de calidad tanto por los propios compañeros de forma grupal como por el profesor. A lo largo de esta comunicación explicamos el proceso seguido, los resultados de las distintas evaluaciones de los trabajos llevadas a cabo por los alumnos, su comparación con la evaluación del profesor y, finalmente, la valoración de la experiencia tanto por parte de los alumnos como del profesor. [ENG] The acquisition of cross-curricular competences is a key issue in the learning process defined in the new degrees adapted to the European Higher Education Area. In this paper we present the approach we have followed to foster the acquisition of cross-curricular competences such as oral communication, group work, the search of resources in the Internet and analysis and synthesis capabilities. Our approach is based on the development of group presentations that will be evaluated by students (peer-assessment) and professors according to a set of quality criteria. This paper explains the process followed in the experience, the results of the different assessments made by students, a comparison with the professors’ evaluations and, finally, the satisfaction of the students and professors with the experience

    This paper presents the FinancES 2023 shared task, organized in the IberLEF 2023 workshop, within the framework of the 39th International Conference of the Spanish Society for Natural Language Processing (SEPLN 2023). The aim of this task is to extend the challenge of sentiment analysis in Spanish to the financial domain, in order to extract the sentiment that a piece of financial information can have for several actors, including the main economic target (i.e., the specific company or asset where the economic fact applies), other companies (i.e., the entities producing the goods and services that others consume) and consumers (i.e., households/individuals). Specifically, two tasks are proposed and evaluated separately. One to identify the main target and to determine the sentiment polarity towards such target, and a second task to assess the sentiment towards both other companies and consumers. The ranking includes results for 10 different teams proposing novel approaches, mostly based on Transformers and generative language models.Este artículo resume la tarea FinancES 2023, organizada en el taller IberLEF 2023, dentro del marco de la 39ª Conferencia Internacional de la Sociedad Española de Procesamiento del Lenguaje Natural (SEPLN 2023). El objetivo de esta tarea es mejorar la materia de la minería de opiniones en español dentro del ámbito financiero realizando el análisis de sentimientos desde distintos puntos de vista. En concreto, se proponen y estudian dos tareas que son evaluadas de forma independiente. La primera tarea consiste en (i) identificar el actor principal asociado a una noticia financiera, y (ii) el sentimiento expresado hacia dicho actor. La segunda tarea consiste en determinar el sentimiento de la noticia (i) hacia otras empresas (i.e., otros agentes económicos), y (ii) hacia los consumidores (i.e., la sociedad). El ranking incluye los resultados de 10 equipos diferentes que proponen enfoques novedosos, en su mayoría basados en Transformers y modelos generativos del lenguaje.This work is part of the research project AIInFunds (PDC2021-121112-I00) funded by MCIN/AEI/10.13039/501100011033 and by the European Union NextGenerationEU/PRTR.

    This paper presents the PoliticEs 2022 shared task, organized at IberLEF 2022 workshop, within the framework of the 38th International Conference of the Spanish Society for Natural Language Processing. This task aims to extract the political ideology from a given user’s set of tweets. Specifically, it focused on the identification of the gender and the profession, as demographic traits, and the political ideology from a binary and multi-class perspective, as a psychographic trait. The PoliticEs task attracted 63 teams that registered through CodaLab. Finally, 20 submitted results and 14 presented working notes describing their systems. Most of the teams proposed transformer-based approaches, although some of them also used traditional machine learning algorithms or even a combination of both approaches.Este artículo presenta la tarea PoliticEs 2022, organizada en el taller IberLEF 2022, en el marco de la 38 edición del Congreso Internacional de la Sociedad Española para el Procesamiento del Lenguaje Natural.

    All sequence files are available from the Genbank database (accession numbers MK142774-MK142779). The protocol is available from protocols.io (DOI: dx.doi.org/10. 17504/protocols.io.xmyfk7w).Noble pen shell or fan mussel, Pinna nobilis Linnaeus (1758), protected since 1992, was incorporated into the Spanish Catalogue of Threatened Species (Category: Vulnerable, Royal Decree 139/2011). The status is presently in the process of being catalogued as critically endangered, pending approval by Spanish Government (https://www.mapama.gob.es/ es/biodiversidad/participacion-publica/Borrador_OM_situacion_critica.aspx). The International Union for the Conservation of Nature (IUCN) alerted the countries of the Mediterranean basin to the “emergent situation” due to serious mortality events suffered by the fan mussel, putting it in serious risk of extinction. Thus, emergency actions have been implemented by Spanish authorities in which several research institutes from all over the country are involved. The parasite, Haplosporidium pinnae, was recently characterized by histology, TEM, SEM and molecular biology techniques and it was considered responsible for the mass mortality of P. nobilis in the Mediterranean Sea. In this context, the aim of this study has been to develop species-specific quantitative PCR (qPCR) protocol carrying out a fast, specific and effective molecular diagnose of H. pinnae. In this sense, the detection limit for qPCR was equal to 30 copies of SSU rDNA / ng of DNA using plasmid alone and when 100ng DNA of non-infected oyster were added. The qPCR assay revealed that 94% of the 32 analysed mantle tissues of fan mussel were infected by H. pinnae, showing a high sensitivity and specificity for its detection (100% if we don’t consider negative and too much degraded samples). This technique will allow us to make quicker follow-ups of the disease, allowing us to get a better understanding of its evolution in order to help in the rescue of P. nobilis populationsProject MAPAMA ref. 28-5310LIFE IPE INTERMARES(LIFE15 IPE ES 012)IFAPA-UCV 014/2018 and co-funded by PHENOFISH ProjectState Plan for Scientific and Technical Research and Innovation 2013-2016, MINECO, ref.
