objectives: the current study aimed to first assess the quality, popularity and importance of websites providing persian health-related information, and second to evaluate the correlation of the popularity and importance ranking with quality score on the internet. materials and methods: the sample websites were identified by entering the health-related keywords into four most popular search eng...

Backround. University rankings are getting very high international media attention, this holds particularly true for the Times Higher Education Ranking (THE) and the Shanghai Jiao Tong University's Academic Ranking of World Universities Ranking (ARWU). We therefore aimed to investigate how reliable the rankings are, especially for universities with lower ranking positions, that often show incon...

Computational docking is the core process of computer-aided drug design; it aims at predicting the best orientation and conformation of a small molecule (drug ligand) when bound to a target large receptor molecule (protein) in order to form a stable complex molecule. The docking quality is typically measured by a scoring function: a mathematical predictive model that produces a score representi...

the objective of this study is to measure the city of tehran’s environmental quality in 2006 (the last census year). primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. based on t...

We construct statistical models to assess whether hospital size will impact the ability to identify "true" hospital ranks in pay-for-performance (P4P) programs. We use Bayesian hierarchical models to estimate the uncertainty associated with the ranking of hospitals by their raw composite score values for three medical conditions: acute myocardial infarction (AMI), heart failure (HF), and commun...

ethods: The National Commission on Prevention Priorities (NCPP) guided this update to a 2001 ranking of clinical preventive services. The NCPP used new preventive service recommendations up to December 2004, improved methods, and more complete and recent data and evidence. Each service received 1 to 5 points on each of two measures—clinically preventable burden and cost effectiveness—for a tota...

We participated in the matching and ranking subtask in TRECVid challenge 2017. The task here was to return a ranked list of the most likely text descriptions that correspond to each video. We adopted a joint visual semantic embedding approach for image-text retrieval and applied to the video-text retrieval task utilizing key-frames extracted by dissimilaritybased sparse subset selection approac...

The process of getting recognized and appreciated in the academic community through journal rankings usually takes many years. The editors of LOGISTICS RESEARCH are glad to report that Jourqual, the professional ranking through the German Association for Business Research (i.e. the “Verband der Hochschullehrer für Betriebswirtschaft”, the 1850 member German equivalent to the United States’ Acad...

In this paper, we deal with efficiency of the diversification of results returned by Web Search Engines (WSEs). We extend a search architecture based on additive Machine Learned Ranking (MLR) systems with a new module computing the diversity score of each retrieved document. Our proposed solution is designed to be used with other techniques, (e.g. early termination of rank computation, etc.). F...

In this paper we are reporting the results obtained participating in the “Evaluating Word Sense Induction and Discrimination Systems” task of Semeval 2007. Our totally unsupervised system performed an automatic self-term expansion process by mean of co-ocurrence terms and, thereafter, it executed the unsupervised KStar clustering method. Two ranking tables with different evaluation measures wer...
