Se evaluó el rendimiento de
cinco índices no paramétricos de riqueza de especies (ICE, Jack1, Jack2, Chao2 y
Bootstrap) utilizando inventarios disponibles para tres grupos de vertebrados dentro de la
Reserva de Biósfera Bañados del Este, Uruguay. Los datos utilizados…

The structured techniques for systems analysis and design are still the most widely known. One of the alternatives of this technique is the JAD methodology (Joint Application Design). This methodology is an improvement with respect to the existing ones -…

The Web has became an obiquitous resource for distributed computing making it relevant to investigate new ways of providing efficient access to services available at dedicated sites. Efficiency is an ever-increasing demand which can be only satisfied with the development…

Este trabajo explora la división de atributos en grupos para poder
mejorar la desambiguación de acepciones (WSD) mediante la combinación de sistemas
entrenados en cada uno de estos grupos de atributos. Los resultados conseguidos
demuestran que sólo k-NN es capaz…

Most search methods in metric spaces assume that the topology of the object collection is reasonably regular. However, there exist nested metric spaces, where objects in the collection can be grouped into clusters or subspaces, in such a way that…

The concept of “approximate” searching has applications in a vast number of fields. Some examples are non-traditional databases (e. g. storing images, fingerprints or audio clips, where the concept of exact search is of no use and we search instead…

This paper shows models of data description that incorporate uncertainty like models of data extension EER, IFO among others. These database modeling tools are compared with the pattern FuzzyEER proposed by us, which is an extension of the EER model…

blic Keys Schemes usually generate two pairs of keys that bear some mathematical relation-usually, a relation of the field known as Number Theory. Identifying a key from another that is given is a problem of great difficulty. This paper presents…

AWA es una arquitectura general para representar información
lingüística producida por procesadores lingüísticos. Nuestro objetivo es definir un
esquema de representación coherente y flexible que sea la base del intercambio de información entre herramientas lingüísticas de cualquier tipo. Los análisis…

Numerical Taxonomy aims to group in clusters, using so-called structure analysis of operational taxonomic units (OTUs or taxons or taxa) through numerical methods.
These clusters constitute families. Structural analysis, based on their phenotypic characteristics, exhibits the relationships, in terms of…
