Assigning UAT Keywords to Astronomy Literature in Science Explorer

Abstract

Para mejorar la facilidad de búsqueda y la relevancia de los artículos astronómicos indexados en Science Explorer (SciX), estamos experimentando con métodos de aprendizaje automático que asignan palabras clave del Tesauro Unificado de Astronomía (UAT, por sus siglas en inglés). El UAT proporciona palabras clave para revistas de la Sociedad Astronómica Estadounidense (AAS, por sus siglas en inglés), Publicaciones de la Sociedad Astronómica del Pacífico (PASP) e Icarus. Sin embargo, desde los primeros artículos en SciX, ningún sistema ha servido a todas las revistas de la comunidad astronómica.. Como vocabulario controlado por el Sistema Simple de Organización del Conocimiento (SKOS), el UAT puede combinar términos alternativos y vincular conceptos relacionados dentro de la astronomía, la heliofísica y las ciencias planetarias. También puede promover el descubrimiento interdisciplinario al conectar conceptos similares en tesauros de otras disciplinas científicas. Como recurso de código abierto, aportado por la comunidad y con licencia libre de la AAS, el UAT se adapta continuamente a los avances científicos. El etiquetador de palabras clave de IA en Scix (KAILAS, por sus siglas en inglés) es una versión del modelo Indus de la NASA optimizada para más de 18 000 artículos astronómicos con palabras clave UAT asignadas por los autores. Seleccionamos el texto de entrenamiento de acuerdo con todos los acuerdos editoriales aplicables. La vista de resúmenes de SciX incluye las asignaciones actuales, a medida que las mejoramos en base a comentarios de la comunidad. A petición de la NASA, el Sistema de Datos Astrofísicos (ADS) se está expandiendo para abarcar la heliofísica, las ciencias planetarias y las ciencias de la Tierra. SciX es la nueva biblioteca digital multidisciplinaria basada en ADS.

To improve the findability and relevance of astronomy papers indexed in the Science Explorer (SciX), we are experimenting with machine-learning methods that assign keywords from the Unified Astronomy Thesaurus (UAT). The UAT supplies journal keywords for the American Astronomical Society (AAS), Publications of the Astronomical Society of the Pacific (PASP), and Icarus. However, from the earliest papers in SciX, no single system has served the astronomical community across all its journals. As a Simple Knowledge Organization System (SKOS) controlled vocabulary, the UAT can combine alternative terms and link related concepts within astronomy, heliophysics, and planetary science. It can also promote cross-disciplinary discovery by connecting to similar concepts in thesauri of other scientific disciplines. As a community-contributed, open-source resource liberally licensed by the AAS, the UAT continuously adapts to scientific advances. Keyword AI Labeler At Scix (KAILAS) is a version of the NASA Indus model fine-tuned on over 18,000 astronomy papers with author-assigned UAT keywords. We selected the training text consistent with all applicable publisher agreements. SciX abstract view includes current assignments as we continue to improve them based on community feedback. At the request of NASA, the Astrophysics Data System (ADS) is expanding to serve heliophysics, planetary science, and earth science. SciX is the new multidisciplinary digital library based on ADS.
