Text mining and machine learning methodologies have been applied toward knowledge discovery in several domains, such as biomedicine and business. Interestingly, in the business domain, the text mining and machine learning community has minimally explored company annual reports with their mandatory disclosures. In this study, we explore the question “How can annual reports be used to predict cha...

System analysts are service providers who are required to work closely with users for the purpose of defining, developing and implementing computer-based systems. Analysts and users in pdvate organizations may have different expectations and proficiencies than those in public organizations, in part due to the types of appli. cations required. Beliefs about how others are supposed to perform and...

Collaborative visual analytics (CVA) involves sensemaking activities within teams of analysts based on coordination of work across team members, awareness of team activity, and communication of hypotheses, observations, and insights. We introduce a new type of CVA tools based on the notion of “team-first” visual analytics, where supporting the analytical process and needs of the entire team is ...

BACKGROUND Studying rare outcomes, new interventions and diverse populations often requires collaborations across multiple health research partners. However, transferring healthcare research data from one institution to another can increase the risk of data privacy and security breaches. METHODS A working group of multi-site research programmers evaluated the need for tools to support data se...

The enormous increase in the volume of remotely sensed data that is being acquired by an ever-growing number of earth observation sensors, led to the situation where the image analysts are at risk to be overwhelmed by the number of images to process. A way to cope with this situation is to use automated feature extraction (AFE) tools to help the image analysts in the extraction of geospatial fe...

BACKGROUND Multilevel models (MLM) offer complex survey data analysts a unique approach to understanding individual and contextual determinants of public health. However, little summarized guidance exists with regard to fitting MLM in complex survey data with design weights. Simulation work suggests that analysts should scale design weights using two methods and fit the MLM using unweighted and...

The purposes of this study were to describe an analytical technique for determining selected 2-dimensional geometric characteristics of a knee joint using lateral knee radiographs and to examine the inter- and intra-analyst reliability of this technique. Five lateral knee radiographs of different knee flexion angles (25-85 degrees at intervals of 15 degrees ) were obtained from five subjects. T...
