The use of data mining techniques in healthcare has been noticing an increased relevance over the last few years, being applied with a variety of objectives, with the most common one being the automatic diagnostic process. In this process, data mining techniques have achieved interesting and successful results. However, when it comes to prognosis the same quality of results is not being achieve...

In this paper, we presented the annotation propagation tool we designed to be used in conjunction with the BRAT rapid annotation tool. We designed two experiments to annotate a corpus of 60 files, first not using our tool, second using our propagation tool. We evaluated the annotation time and the quality of annotations. We shown that using the annotation propagation tool reduces by 31.7% the t...

This session features exciting keynote speeches by Rajeev Madhavan (Chairman & CEO, Magma Design Automation), Michael Reinhardt (CEO & President, RubiCAD), and Shekhar Borker (Intel Fellow & Director of Circuit Research Lab). In the first keynote speech, titled “Addressing the IC Designer’s Needs: Integrated Design Software for Faster, More Economical Chip Design”, Rajeev Madhaven highlights th...

Crowdsourced demarcations of object boundaries in images (segmentations) are important for many vision-based applications. A commonly reported challenge is that a large percentage of crowd results are discarded due to concerns about quality. We conducted three studies to examine (1) how does the quality of crowdsourced segmentations differ for familiar everyday images versus unfamiliar biomedic...

Examining the validity of test results using specialised methods is still a relatively new venture and many different approaches are taken to the same task. This paper discusses some of the reasons why discrepant results and differing conclusions may be arrived at by clinicians or researchers, depending on their theoretical and practical choices. These choices include whether to test for effort...

BACKGROUND This study aimed at determining the validity of the Pediatric Quality of Life Inventory 4.0 (PedsQL™ 4.0) for the measurement of health-related quality of life (HRQOL) in Colombian children. METHODS Validation study of measurement instruments. The PedsQL™ 4.0 was applied by convenience sampling to 375 pairs of children and adolescents between the ages of 5 and 17 and to their paren...

Researchers are gaining an interest in the concept of wisdom, a more holistic yet often ineffable educational outcome. Models of wisdom abound, but few have rigorously tested measures. This study looks at Brown's (2004a, 2004b) Model of Wisdom Development and its associated measure, the Wisdom Development Scale (WDS; Brown & Greene, 2006). The construct validity, measurement invariance, criteri...

This paper investigates validity analysis of alternative clustering results obtained using the algorithm named Multiobjective K-Means Genetic Algorithm (MOKGA). The reported results are promising. MOKGA gives the optimal number of clusters as a solution set. The achieved clustering results are then analyzed and validated under several cluster validity techniques proposed in the literature. The ...
