Compilación de un macrotesauro conceptual para los centros españoles de información juvenil

The process of building a thesaurus for the Spanish Youth Information Centres of the seventeen autonomous governments is presented. The previous Thematic Classification of the Spanish Youth Information Net of Centers was used as the starting point. The firs structural model was analysed and deeply, and, after their assessment, the other terms were treated as descriptors inside the new hierarchical structure. As a result, the thesaurus has ten macrohierarchies, a total of 3,384 terms, 2,543 descriptors, 841 linguistic equivalents, 183 use notes explicative, 1,683 associative relations and 1,684 cross-referencesSe presenta el proceso de construcción de un tesauro para los centros de información juvenil de las diecisiete autonomías españolas. Se partió de la macroestructura de la anterior Clasificación Temática de la Red Espafiola de Servicios de Información Juvenil, analizando y modificando profundamente su primer nivel estructural. Los demás términos fueron incorporados tras su evaluación como individuales dentro de la nueva estructura jerárquica. Como resultado, el tesauro quedo configurado en diez macrofamilias que incluyen un total de 3.384 términos, de los cuales 2.543 son descriptores y 841 no descriptores, 183 notas de alcance, 1.638 relaciones asociativas y 1.684 reenvío

Idea Analysis for the Development of Clinical Trial Strategies

Idea Analysis was investigated to determine its ability to organize scientific information and explain the results of specialists\u27 deliberations in designing new clinical trials. Ideas have long been recognized as the engine of creativity. By focusing on the capture of ideas from the scientific literature, idea analysis procedures enable the arrangement of the information into forms consistent with those developed by subject specialists. The most obvious example is the concept structure. Ideas containing a common frequently occurring term/phrase can be depicted as a primary node in the concept network. Related terms will appear as elements associated with that node. Ideas containing couplets of primary nodal terms/phrases can be used to link nodes, thus, completing the paths in the network. Using this methodology, information specialists can build and maintain knowledge structures for use by students, subject specialists and interested others. In contrast with expert systems, idea analysis does not attempt to duplicate thought processes performed by experts in a subject. Instead, it focuses on the management of ideas and the arrangement of those ideas using organizational models. The application of these techniques to the scientific literature dealing with brain tumors and to clinical trial protocols developed by subject specialists is illustrative. This study showed that, in the brain tumor literature and clinical trial protocols, the idea analysis approach was effective in accomplishing the two tasks required: 1. Organization of complex material into succinct and understandable descriptions--tabular and graphic; 2. provision of explanations of expert-derived research strategies and/or plans. This methodology enhanced identification, extraction, computerization and incorporation of ideas into knowledge structures in an efficient and effective manner
