Automatic Essay Assessor (AEA) is a system that utilizes information retrieval techniques such as Latent Semantic Analysis (LSA), Probabilistic Latent Semantic Analysis (PLSA), and Latent Dirichlet Allocation (LDA) for automatic essay grading. The system uses learning materials and relatively few teacher-graded essays for calibrating the scoring mechanism before grading. We performed a series o...

In 2005, the International Society of Urological Pathology (ISUP) introduced several modifications to the original Gleason system that were intended to enhance the prognostic power of Gleason score (GS). The objective of this study was to clinically validate the 2005 ISUP Gleason grading system for its ability to detect metastasis. We queried our institutional RP database for men with NCCN clin...

Correlation of Visick grading was done with serial endoscopies in 19 patients operated for duodenal ulceration. Deeper mucosal lesions like ulceration showed good association with Visick grading (100%), while superficial mucosal lesions were mostly asymptomatic and therefore, caused disparity in grading. Moreover, as symptoms and endoscopic findings changed with passage of time, it was conclude...

BACKGROUND AND PURPOSE Novel angiographic grading scales for the assessment of intracranial aneurysms treated with flow-diverting stents have been recently developed because previous angiographic grading scales cannot be applied to these aneurysms. The purpose of this study was to evaluate the inter- and intraobserver variability of the novel O'Kelly Marotta grading scale, which was developed s...

Systematic screening for diabetic retinopathy using retinal photography has been shown to reduce the incidence of blindness among people with diabetes. The implementation of diabetic retinopathy screening programmes faces several challenges. Consequently, methods for improving the efficiency of screening are being sought, one of which is the automation of image grading involving detection of im...

BACKGROUND Preoperative histologic grading was used to decide the length of the margin of resection in adenocarcinoma of colon and rectum. OBJECTIVES The aim of the present study was to determine the accuracy of preoperative histologic grading by comparison with postoperative histologic grading. MATERIAL AND METHOD Preoperative and postoperative histologic grading of patients with adenocarc...

For visual grading experiments, which are an easy and increasingly popular way of studying image quality, hitherto used data analysis methods are often inadequate. Visual grading analysis makes assumptions that are not statistically appropriate for ordinal data, and visual grading characteristic curves are difficult to apply in more complex experimental designs. The approach proposed in this pa...

This well-designed site has links that cover multiple aspects of testing and grading from a basic introduction to testing and measurement to such specific issues as improving multiple choice tests and advice on writing and grading essay questions. Assessment Terminology: A Glossary of Useful Terms (New Horizons for Learning). This site contains clear definitions of assessment terms from account...

Computer grading of hardwood lumber promises to avoid regrading of the same lumber because of disagreements between the buyer and the seller. However, the first generation of computer programs for hardwood lumber grading simplify the process by modeling defects on the board as rectangles. This speeds up the grading process but can inadvertently put a board into a lower grade because rectangular...

AIMS To assess the cost-effectiveness of an improved automated grading algorithm for diabetic retinopathy against a previously described algorithm, and in comparison with manual grading. METHODS Efficacy of the alternative algorithms was assessed using a reference graded set of images from three screening centres in Scotland (1253 cases with observable/referable retinopathy and 6333 individua...
