In this paper, we present an approach to student's evaluation in a well-defined domain based on a semantic network. A similarity matrix based on the semantic memory structure of humans is used to build a semantic distance model in order…

Muchos son los factores que determinan la dinámica de poblaciones de plantas entre los cuales hay demográficos (variabilidad ambiental,
densidad poblacional, etc.) y genéticos (variabilidad genética de los individuos, deriva genética y/o depresión por consanguinidad). Entender
los efectos de esos…

El centro de iniciación del aprendizaje histórico - geográfico lo constituye la localidad. Es donde el alumno confronta diariamente su cotidianidad, es el hecho simple, lo que siente, vive y mantiene contacto todos los días, es su lugar de desenvolvimiento,…

This paper describes the development of an image retrieval
system that combines probabilistic and ontological information1. The
process is divided in two different stages: indexing and retrieval. Three
information flows have been created with different kind of information
each one:…

Inside an organization there is information that can only be generated by people, then, when a decision maker in any time and anywhere of an organization requires this information, he/she has to solicit it to who has the ability of…

Most formalisms for representing common-sense knowledge allow incomplete and potentially inconsistent information. When strong negation is also allowed, contradictory conclusions can arise. A criterion for deciding between them is needed. The aim of this paper is to investigate an inherent…

Semantic, Syntax and Pragmatic represent in themselves three different
approaches to the same concern: semiotic structure.
The aim of this paper is to provide a general view of Landowskian Semiotics,
discussing the results achieved from different fields of knowledge to…

Current approaches to generation for machine translation make use of direct-replacement templates, large grammars, and knowledge-based inferencing techniques. Not only are rules language-specific, but they are too simplistic to handle sentences that exhibit more complex phenomena. Furthermore, these systems are…

This paper describes the connection memory, a machine for concurrently manipulating knowledge stored in semantic networks. We need the connection memory because conventional serial computers cannot move through such networks fast enough. The connection memory sidesteps the problem by providing…

En este trabajo describimos la primera prueba sistemática realizada para evaluar el rendimiento de Sentitext, un sistema de análisis de sentimiento aún en fase de desarrollo. A diferencia de la mayoría de los sistemas existentes, el funcionamiento de Sentitext está…
