Mejora de Contraste y Compensación en Cambios de la Iluminación

In this paper a contrast operator built by means of two primitives involving Weber’s Law is presented. The proposed contrast mapping has two objectives, in the first place the contrast enhancement and in the second, the normalization of the processed image. The contrast enhancement is based on the image background detection; this parameter is computed through the analysis of the regional minimu...

Aprendizaje Automático versus Expresiones Regulares en la Detección de la Negación y la Especulación en Biomedicina

In this paper, we present a machine learning system that identify the negation and speculation signals in biomedical texts, in particular, in the BioScope corpus. The objective of this research is to compare the efficiency of this approach focused on machine learning with which it is based on regular expressions. Among the systems that follow the latter approach, we used NegEx because of its av...

n a paradox experienced by many IT managers, organizational information systems (OISs) are implemented and function exactly as designed—a success by all objective measures—yet users are still disappointed and consider them unsuccessful. Exploring this paradox here, we recommend ways to reduce the root causes of such disappointment. Researchers and practitioners alike have long focused on the su...
