DEXML: A First Step Toward a UML Based Implementation Framework for PLCS

2011

Data exchange specifications not only must be broad and general to achieve acceptance, but also must be customizable in a controlled and interoperable manner to be useful. The Product Life Cycle Support (PLCS) suite of data exchange specifications (known as DEXs) uses templates to enable controlled customizability without sacrificing breadth or interoperability. DEXs are business context-specific subsets of ISO 10303 Application Protocol (AP) 239, subject to additional constraints imposed by the templates. A PLCS template defines how AP239 entities and their attributes will be instantiated using an externally-defined controlled vocabulary defined in a Reference Data Library. Template instan…

La iconografía en la era digital: hacia una heurística para el estudio del contenido de las imágenes medievales

2014

Este artículo invita a reflexionar sobre la validez de la iconografía como método para describir los temas representados en las obras artísticas medievales. En esta ocasión, se ha puesto un mayor énfasis en investigar sus implicaciones epistemológicas y los sesgos que resultan del proceso de transformar las imágenes en palabras. El objetivo principal es tratar de que aflore la llamada 'brecha semántica', una especie de barrera que impide representar verbalmente un medio no léxico, como es el visual, de manera satisfactoria y sin mermas. Tras un sucinto recorrido por el pensamiento griego, con un especial interés por la écfrasis, se sugiere que el aparente equilibrio entre las capacidades se…

El arte de poesía castellana. Desde el pensamiento poético de Encina hacia una colección digital de tratados poéticos

2017

This paper presents the project Poetriae, focusing on the steps already taken and on the ongoing work, as well as on its methods and future steps. Mainly, Poetriae aims at building a digital library of Medieval and Golden Age Castilian poetry treatises. It will create digital editions for them, by philologically marking up each metrical and poetic concept in an unambiguous way, in order to allow treatises to be retrievable not just by bibliographic metadata, but also by key concepts, such as poetic genre, stanza types, rhyme, etc. The project also intends to enable automatic analysis and visualizations of such data. Design and application of specific vocabularies for poetry and metrics are …

Perspective: Essential study quality descriptors for data from nutritional epidemiologic research

2017

Pooled analysis of secondary data increases the power of research and enables scientific discovery in nutritional epidemiology. Information on study characteristics that determine data quality is needed to enable correct reuse and interpretation of data. This study aims to define essential quality characteristics for data from observational studies in nutrition. First, a literature review was performed to get an insight on existing instruments that assess the quality of cohort, case-control, and cross-sectional studies and dietary measurement. Second, 2 face-to-face workshops were organized to determine the study characteristics that affect data quality. Third, consensus on the data descrip…

The current progress in sequencing projects calls for rapid, reliable and accurate function assignments of gene products. A variety of methods has been designed to annotate sequences on a large scale. However, these methods can either only be applied for specific subsets, or their results are not formalised, or they do not provide precise confidence estimates for their predictions. We have developed a large-scale annotation system that tackles all of these shortcomings. In our approach, annotation was provided through Gene Ontology terms by applying multiple Support Vector Machines (SVM) for the classification of correct and false predictions. The general performance of the system was bench…
