BACKGROUND: Clinical trial protocols are the foundation for advancing medical sciences, however, the extraction of accurate and meaningful information from the original clinical trials is very challenging due to the complex and unstructured texts of such documents. Named entity recognition (NER) is a fundamental and necessary step to process and standardize the unstructured text in clinical trials using Natural Language Processing (NLP) techniques. METHODS: In this study we fine-tuned pre-trained language models to support the NER task on clinical trial eligibility criteria. We systematically investigated four pre-trained contextual embedding models for the biomedical domain (i.e., BioBERT, BlueBERT, PubMedBERT, and SciBERT) and two models for the open domains (BERT and SpanBERT), for NER tasks using three existing clinical trial eligibility criteria corpora. In addition, we also investigated the feasibility of data augmentation approaches and evaluated their performance. RESULTS: Our evaluation results using tenfold cross-validation show that domain-specific transformer models achieved better performance than the general transformer models, with the best performance obtained by the PubMedBERT model (F1-scores of 0.715, 0.836, and 0.622 for the three corpora respectively). The data augmentation results show that it is feasible to leverage additional corpora to improve NER performance. CONCLUSIONS: Findings from this study not only demonstrate the importance of contextual embeddings trained from domain-specific corpora, but also shed lights on the benefits of leveraging multiple data sources for the challenging NER task in clinical trial eligibility criteria text.

The World Register of Marine Species (WoRMS), The Interagency Taxonomic Information System (ITIS, Report Taxonomic Serial No 157821), and Wikispecies all identify Leske (1778) as the author of the taxon Echinoidea. They base this attribution on the synonymy of Durham et al. (1966: U297) who stated Class ECHINOIDEA Leske, 1778 [nom. transl. Bronn, 1860, p. 295 (ex order Echinoidea dOrbigny, 1852 [sic], p. 114, nom correct. pro ordo Echinus Leske, 1778, p. xvi [sic])]. This confusing construction led to a strange result in which the taxon Echinoidea was attributed to an author who never used that name (Leske), whilst it deprived the author who established it (Schumacher) and the one who first conceived the grouping (Bruguire) of any credit. This note examines the works of various authors credited with the authorship of the taxon Echinoidea, particularly Leske, dOrbigny, von Zittel, and Bronn, and concludes that the taxon Echinoidea should be attributed to Schumacher, 1817.

This article attempts to hypothetically reflect on how historians of science will write their research on the development of the covid-19 pandemic in Israel in the future, within a context that includes: the political crisis experienced by the country at that time; the history of the public health institutions established from the time of the first Jewish settlers in Palestine, at the beginning of the twentieth century, and slightly modified by a law of 1994; the conceptual schemes developed during the last decades by historians of public health and pandemics in general.

El presente artículo representa un intento de reflexionar hipotéticamente sobre la manera en que los historiadores de la ciencia escribirán en el futuro sus investigaciones sobre el desarrollo de la pandemia de la covid-19 en Israel, dentro de un contexto que incluye: la crisis política que vivió el país en esos momentos; la historia de las instituciones de salud pública establecidas desde la época de los primeros colonos judíos en Palestina, a principios del siglo XX, y modificadas ligeramente por una ley de 1994; los esquemas conceptuales desarrollados durante las últimas décadas por historiadores de la salud pública y las pandemias en general.
