Knowledge-intensive processes are widely used to recover from errors, handle exceptional cases and complaints, and to improve or adapt a process itself. In this context, evolved Business-Process Reengineering (BPR) techniques are changing to give some answers to this reality. In…

This paper describes an approach to On Line Analytical Processing (OLAP), expresed in the declarative programming paradigm.
We define a collection of functions that capture some of the functionality currently provided by multidimensional database product. This is done by defining…

An important problem in Mineralogy, is to accomplish an adequate representation of a great amount of data coming from different geological environments, in order to characterize a particular geologic region in terms of its tectonic setting. With such Databases of…

DATA INTEGRATION IS A PROCESS OF RETRIEVING, MERGING AND STORING OF DATA ORIGINATED IN HETEROGENEOUS SOURCES OF DATA. THE MAIN PROBLEM FACING THE DATA INTEGRATION IS THE STRUCTURAL AND SEMANTIC HETEROGENEITY OF PARTICIPATING DATA. A CONCERN OF RESEARCH COMMUNITIES IN…

EL MONITOREO DEL MEDIO AMBIENTE ES UNA DE LAS MUCHAS APLICACIONES DE LAS REDES INALÁMBRICAS DE SENSORES. DADO QUE ESTAS REDES ESTÁN DENSAMENTE POBLADAS Y QUE LAS VARIACIONES LOCALES DE VARIABLES AMBIENTALES SON PEQUEÑAS, LOS NODOS DE SENSADO GENERAN UNA…

IN PATTERN RECOGNITION (FEATURE SELECTION, SUPERVISED CLASSIFICATION, UNSUPERVISED CLASSIFICATON, ETC) DATA MODIFICATIONS ARE VERY COMMON. THIS DUE TO MANY REASONS, FOR EXAMLE: DATA ACQUISITION ERROR FIXING; SPECIALIST CHANGES SAMPLE CLASSIFICATION; ELIMINATION OF SOME DATA; NEW DATA; ETC. THEN, MANY TIME…

HOY EN DÍA, EL USO DE SISTEMAS DE COMUNICACIÓN DIGITALES HA AUMENTADO DE TAL FORMA QUE EL ANCHO DE BANDA EN LAS REDES RESULTA AFECTADO. ESTE PROBLEMA PUEDE SOLUCIONARSE IMPLEMENTANDO ALGORITMOS DE COMPRESIÓN DE DATOS EN DISPOSITIVOS DE COMUNICACIÓN REDUCIENDO…

IN THIS PAPER, AN EXTENSION TO THE C-MEANS ALGORITHM THAT CONSIDERS OBJECT DESCRIPTIONS WITH QUANTITATIVE AND QUALITATIVE FEATURES (MIXED DATA) IS PROPOSE. IN ADDITION, THE ALGORITHM CONSIDERS MISSING DATA. THESE KINDS OF DESCRIPTIONS (MIXED DTA) ARE VERY FRECUENT IN SOFT…

A DATA STRUCTURE USEFUL FOR PREFIX SEARCH IN A VERY LARGE DICTIONARY WITH AN ANLIMITED QUERY STRING IS DISCUSSED. THIS PROBLEM IS IMPORTANT FOR MORPHOLOGICAL ANALYSIS OF INFLECTIVE LANGUAGES, INCLUDING PARTICULARY DIFFICULT CASES SUCH AS GERMAN WORD CONCATENATION OR JAPANESE…

THE THESIS PRESENTS AN APPROACH TO VERIFY THE CONSISTENCY OF GENERALIZED GEOSPATIAL DATA AT A CONCEPTUAL LEVEL. THE PRINCIPAL STAGES OF PROPOSED METHODOLOGY ARE ANALYSIS, SYNTHESIS, AND VERIFICATION. ANALYSIS IS FOCUSED ON EXTRACTING THE PECULIARITIES OF SPATIAL RELATIONS BY MEANS…
