Large-Scale Examination of Academic Publications Using Statistical Models
نویسندگان
چکیده
We describe our experiences in three collaborative visual analytics projects. The projects center on large-scale examination of academic publications using statistical models. Each project involves a multidisciplinary team of social scientists, machine learning researchers, and experts in various academic fields. We highlight design guidelines learned from these experiences. In many cases, effective analysis results only after aligning the visualization with the analysis tasks, the capabilities of the modeling tools, and concepts meaningful to the domain experts. Substantiating findings from the analyses often requires verifying and modifying the underlying statistical models. In the examples below, we demonstrate that alignment allows analysts to verify model outputs by comparing them to domain knowledge and gain trust in the validity of findings derived from the models. Verification often leads to model modifications (changes in assumptions, parameter search, or sensitivity analysis); visualization can expose modeling abstractions, and help model builders better understand and alter the characteristics of the models. Displaying appropriate units of analysis also facilitates communication among collaborators with different backgrounds and expertise.

The use of test scores from large‐scale assessment surveys: psychometric and statistical considerations
Background Recent publications have re-ignited interest in the approach to modeling used to generate achievement measures for large scale assessments such as NAEP and PISA. Even though the foundations and statistical methodology behind these models have been extensively covered for over 3 decades (Mislevy 1984, 1985; Mislevy and Sheehan 1987), there continue to be concerns about their ability t...
متن کاملA TWO-STAGE DAMAGE DETECTION METHOD FOR LARGE-SCALE STRUCTURES BY KINETIC AND MODAL STRAIN ENERGIES USING HEURISTIC PARTICLE SWARM OPTIMIZATION
In this study, an approach for damage detection of large-scale structures is developed by employing kinetic and modal strain energies and also Heuristic Particle Swarm Optimization (HPSO) algorithm. Kinetic strain energy is employed to determine the location of structural damages. After determining the suspected damage locations, the severity of damages is obtained based on variations of modal ...

Climate change is found to be the most important global issue in the 21st century, so to monitor its trend is of great importance. Atmospheric General Circulation Models because of their large scale computational grid are not able to predict climatic parameters on a point scale, so small scale methods should be adapted. Among downscaling methods, statistical methods are used as they are easy to...
متن کاملEffect of large blocks position on stability analysis of block-in-matrix slopes
Bimrocks are complex geomaterials that are defined as mixtures of rocks composed of geotechnically significant blocks within a matrix of finer texture. Bimslopes are made from bimrocks and are usually seen in weathered and shallow environments. Some characteristics of blocks affecting the strength of bimrocks include VBP (Volumetric Block Proportion), orientation, and arrangement, which have im...
