Medical records contain many terms that are difficult to process. Our aim in this study is to allow visual exploration of the information in medical databases where texts present a large number of syntactic variations and abbreviations by using an interface that facilitates content identification, navigation, and information retrieval. We propose the use of multi-term tag clouds as content representation tools and as assistants for browsing and querying tasks. The tag cloud generation is achieved by using a novelty mathematical method that allows related terms to remain grouped together within the tags. To evaluate this proposal, we have carried out a survey over a spanish database with 24,481 records. For this purpose, 23 expert users in the medical field were tasked to test the interface and answer some questions in order to evaluate the generated tag clouds properties. In addition, we obtained a precision of 0.990, a recall of 0.870, and a F1-score of 0.904 in the evaluation of the tag cloud as an information retrieval tool. The main contribution of this approach is that we automatically generate a visual interface over the text capable of capturing the semantics of the information and facilitating access to medical records, obtaining a high degree of satisfaction in the evaluation survey.

Tag clouds are tools that have been widely used on the Internet since their conception. The main applications of these textual visualizations are information retrieval, content representation and browsing of the original text from which the tags are generated. Despite the extensive use of tag clouds, their enormous popularity and the amount of research related to different aspects of them, few studies have summarized their most important features when they work as tools for information retrieval and content representation. In this paper we present a summary of the main characteristics of tag clouds found in the literature, such as their different functions, designs and negative aspects. We also present a summary of the most popular metrics used to capture the structural properties of a tag cloud generated from the query results, as well as other measures for evaluating the goodness of the tag cloud when it works as a tool for content representation. The different methods for tagging and the semantic association processes in tag clouds are also considered. Finally we give a list of alternative for visual interfaces, which makes this study a useful first help for researchers who want to study the content representation and information retrieval interfaces in greater depth.

Tag clouds are now very popular in websites because of its ability to recruit the activity of web users into effectively information retrieval. In recent years, although there are many researches on English tag clouds, few are known about Chinese tag clouds. In this paper, we investigated the layout of the Chinese tag cloud, and analyzed eight visual features of the Chinese tag cloud according to users browsing behavior. Our results could provide a theoretical reference for the tag cloud designers.

Changes in the teaching methodology of an undergraduate psychology course are described. The goals were to increase student responsibility for and participation in the course and to promote critical thinking systematically. Responsibility was increased by having students write their own essay questions for exams. Active participation during class meetings was encouraged by using the technique of Socratic dialogue. Critical thinking was promoted by utilizing Bloom's taxonomy. Student responses on course evaluation forms indicated a high degree of satisfaction with these methods.

Piping design for ‘revamp’ projects in the process industry requires the retrieval of large amounts of ‘as-built’ data from existing process plant installations. Positional data with a high degree of accuracy are required. Photogrammetry, the science of measurement from photographs, was identified in Imperial Chemical Industries plc (ICI) as a suitable tool for information retrieval. The mathematical formulation enabling the definition of three-dimensional positions from photographic information is described. The process of using ICI's photogrammetric system for the definition of complete objects such as structures and pipes is illustrated. The need for specialized photogrammetric software for design purposes is explained. A case study describing how the photogrammetric system has been applied is described and graphical outputs from this exercise are shown. It is concluded that this particular photogrammetric system has proved to be a cost effective and accurate tool for the retrieval of ‘as-built’ information.

El presente estudio tiene como objetivo conocer el grado de satisfacción de los usuarios con los servicios deportivos del Campus Universitario de Espinardo. En el estudio participaron 61 sujetos de ambos sexos y con un rango de edad entre 18 y 66 años. Para la realización de la encuesta se utilizó un instrumento validado, el "Cuestionario de valoración de servicios deportivos (EPOD2)". Los resultados muestran como los clientes manifiestan un alto grado de satisfacción en prácticamente todas las dimensiones analizadas. Los apartados de variedad, modernidad y mantenimiento de materiales y posibilidades de sugerencias son los que presentan un mayor grado de descontento por parte de los usuarios de las instalaciones, aunque a nivel general la satisfacción en estos ítems sigue siendo superior al 50%. En conclusión, la satisfacción por parte de los usuarios es muy alta, manifestando solo necesidades de mejora en aspectos concretos de algunas dimensiones.

There is an explosion in the amount of textual documents that have been generated and stored in recent years. Effective management of these documents is essential for better exploitation in decisional analyses. In this context, the authors propose their CobWeb multidimensional model based on standard facets and dedicated to the OLAP (on-line analytical processing) of XML documents; it aims to provide decision makers with facilities for expressing their analytical queries. Secondly, they suggest new visualization operators for OLAP query results by introducing the concept of Tag clouds as a means to help decision-makers to display OLAP results in an intuitive format and focus on main concepts. The authors have developed a software prototype called MQF (Multidimensional Query based on Facets) to support their proposals and then tested it on documents from the PubMed collection.
