Resumen
Los sistemas de búsqueda de respuestas (SBR) son una alternativa a los tradicionales sistemas de recuperación de información tratando de ofrecer respuestas precisas y comprensibles a preguntas factuales, en lugar de presentar al usuario una lista de documentos relacionados con su búsqueda. Se ha evaluado la eficacia de cuatro SBR disponibles en la Web �QuALiM, SEMOTE, START, y TrueKnowledge�, mediante una amplia muestra de preguntas de definición, factuales y de lista, pertenecientes a distintos dominios temáticos. Se utilizó una colección de 500 preguntas cuyas respuestas fueron valoradas por los usuarios y, posteriormente, se aplicaron varias medidas para su evaluación (MRR, TRR, FHS, MAP y precisión). Se observa que START y TrueKnowledge presentan un nivel aceptable de respuestas correctas, precisas y en una secuencia bien ordenada. Los resultados obtenidos revelan el potencial de esta clase de herramientas en el ámbito del acceso y la recuperación de información de dominio general.
