Finding Rotten Eggs: A Review Spam Detection Model using Diverse Feature Sets
Published in: KSII Transactions on Internet & Information Systems
Oct 01, 2018
Social media enables customers to share their views, opinions and experiences as product reviews. These product reviews facilitate customers in buying quality products. Due to the significance of online reviews, fake reviews, commonly known as spam reviews are generated to mislead the potential customers in decision-making. To cater this issue, review spam detection has become an active research area. Existing studies carried out for review spam detection have exploited feature engineering...

Currently, Big Data is an important concept due to the pervasive use of electronic devices, computerization, and information sharing worldwide. Despite the focus on Big Data, studies lack an explicit definition of the Big Data concept. Big Data is assumed to present natural solutions to government and private sectors, but the practical results of Big Data in other sectors are still unknown. This paper discusses Big Data concerning two perspectives: decision-making process and knowledge creatio...
Managing patients’ data with clinical decision support systems: a factual assessment
Published in: Journal of Decision Systems
Sep 30, 2018
In assessing the benefits of using e-health systems, the main goal of this study is to evaluate the real use of the clinical decision support system (CDSS) between 2007 and 2014 in Canada’s healthcare sector. The quantitative method was based on data collected by the National Physician Survey in Canada. Results indicate that 63.8% of healthcare providers were using a CDSS at work in 2014 to help them in the decision-making process, a sixfold improvement since 2007. As for usage rate by s...

On Utilizing Model Transformation for the Performance Analysis of Queueing Networks
Published in: Journal of Software Engineering and Applications
Sep 28, 2018
In this paper, we present an approach for model transformation from Queueing Network Models (QNMs) into Queueing Petri Nets (QPNs). The performance of QPNs can be analyzed using a powerful simulation engine, SimQPN, designed to exploit the knowledge and behavior of QPNs to improve the efficiency of simulation. When QNMs are transformed into QPNs, their performance can be analyzed efficiently using SimQPN. To validate our approach, we apply it to analyze the performance of several queueing netwo...

Abstract: Over the last quarter of the 20th century, higher education institutions (HEIs) were affected by social and economic policy changes. These changes encouraged HEIs to adopt entrepreneurial behaviour and act as a business. This paper is a review, critique, and discussion of literature on the new shape of higher education institutions and the need for transformational leadership in entrepreneurial universities. This review shows that academic leaders are needed to build and maintain the ...
