Abstrac: In the following article we present an overview of recent works oriented to the query planning with quality control in the Information Systems Based on Mediators. In our study the quality in plans and resulting information of the queries are important aspects. We describe proposals oriented to face the problem from a Web Information Systems viewpoint, by means of traditional query optimization, Multiagent Systems and Mediators Systems. Finally, we present some open problems in this field and we describe an initial proposal to face them.

Resumen: En el siguiente artículo se presenta una revisión de los recientes trabajos orientados a la Planificación de Consultas con control de calidad en los Sistemas de Información Basados en Mediadores, teniendo en cuenta la calidad tanto de los planes, como de la información resultado de las consultas. Se describen las propuestas orientadas a enfrentar el problema desde el marco de acción de los Sistemas de Información Web, pasando por la optimización de consultas tradicional, los Sistemas Multiagente y los Sistemas Mediadores. Por último se presentan algunos problemas abiertos en este tópico de investigación y se plantea una propuesta inicial para enfrentarlos.
