Métricas de Madurez en Conceptualización de Sistemas Expertos

Planning is very important to run a project so that to develop expert systems or knowledge based systems, that activity has certain particularities that turn it into a complex one. It has to be considered human effort (person/time) cost and time in order to plan. For this there are metrics, that enable to obtain information and to generate knowledge of the evolution and the scope of the project...

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...
