Abstract

UN SISTEMA INFORMATICO TOMA COMO ENTRADA UNA JERARQUIA DE ERRORES INICIAL KB{SUB,0} Y UN CONJUNTO DE TRANSCRIPCIONES DE SESIONES ANOTADAS C={<{PI}{SUB,J}, {RH}{SUB,J}>} Y SE LE PROPORCIONA UN CONJUNTO ESPECIFICADO DE OPERADORES DE REVISION T = {{DS}{SUB,J}} EN DONDE CADA {DS}{SUB,J} ES T SITUA UNA JERARQUIA DE ERRORES KB EN UNA JERARQUIA {DS}{SUB,J}(KB). A ESTA JERARQUIA DE ERRORES REVISADA {DS}{SUB,J} (KB) SE LE LLAMA UN VECINO DE KB Y EL CONJUNTO DE TODOS LOS VECINOS DE KB, N(KB) = {{DS}{SUB,I}(KB)} ES LA VECINDAD DE LOS KB. EL SISTEMA INFORMATICO UTILIZA T PARA ESCALAR DESDE LA JERARQUIA DE ERRORES INICIAL KB{SUB,0} A TRAVES DE JERARQUIAS SUCESIVAS KB{SUB,1}...KB{SUB,M}, CON UNA EXACTITUD EMPIRICA MAS ALTA SUCESIVAMENTE SOBRE C. LA JERARQUIA FINAL, KB{SUB,M}, ES UN OPTIMO DE POSICION EN EL ESPACIO DEFINIDO POR LOS OPERADORES DE REVISION. EN CADA PASO, PARA IR DESDE UNA JERARQUIA DE ERRORES KB{SUB,I} HASTA SU VECINO KB{SUB,I+1}, LA PRESENTE INVENCION DEBE EVALUAR LA PRECISION DE KB{SUB,I}SOBRE C, ASI COMO LA PRECISION DE CADA KB ES N(KB{SUB,I}). SI SE ENCUENTRA QUE CUALQUIER KB ES MAS PRECISO QUE KB{SUB,I}, ESTA JERARQUIA KB{SUP,*} SE CONVIERTE EL NUEVO PATRON, ETIQUETADO KB{SUB,I+1}, Y EL PROCESO DE REVISION DE LA TEORIA SE REPITE, BUSCANDO UN VECINO DE ESTE KB {SUB,I+1} QUE SEA MAS PRECISO QUE KB{SUB,I+1} SOBRE EL CONJUNTO DE EJEMPLOS DE C. DE LO CONTRARIO, SI NINGUN KB ES MAS PRECISO QUE KB{SUB,I}, EL PROCESO DE ESCALADA VOLVERA A ESTE A KB{SUB,I} Y CONCLUIRA.
