    Este artículo trata el problema de análisis de investigación científica a través de múltiples colecciones disciplinarias. Nuestro método se aplica en: (1) descubrimiento sin supervisión de temas científicos a través de múltiples disciplinas; (2) comparación de los temas de misma disciplina; y (3) análisis temporal.

    This paper addresses the problem of scientific research analysis across multiple research literature collections. We use topic modeling in three novel comparative tasks: (1) unsupervised discovery and comparison of scientific topics across multiple disciplines; (2) comparison of topics within the same discipline; (3) analysis of topic evolution over time within and across disciplines and trend analysis.
