Expert systems and information retrieval: examples of applications

Abstract

The new information and communication technologies have provided with new techniques in information sources retrieval. The possibility to access to great databases —both specific and multidisciplinary— has transformed automated information retrieval a normal practice. That is why information systems must be created with the aim of the use and dissemination of the information stored in them, and having in mind the final user’s access as a very convenient goal. So, the design and implementation of tools to make easier information retrieval is a thriving research line. Several of such systems are described, as research projects of the European Union or in the field of public administration citizen’s information. The interfaces are classified into three levels: remind and type (e. g., retrieval languages), take a glance and do (menus), and talk, listen and ask, based on expert systems. Some examples of each category developed by the author of the paper are explained, together with their design and implementation methodology. These experiences demonstrate that using Artificial Intelligence tools and techniques results in the satisfaction of both the developer and the user.
