Owing that class diagrams constitute the backbone of object-oriented (OO) software development, many metrics were proposed to measure internal quality attributes such as the structural complexity, coupling, size, etc. But none of the proposed metrics take into account the added complexity when class diagrams are complemented by Object Constraint Language (OCL) expressions. OCL expressions impro...

Metrics have long been used to measure and evaluate software products and processes. Many metrics have been developed that have lead to different degrees of success. Software architecture is a discipline in which few metrics have been applied, a surprising fact given the critical role of software architecture in software development. Software product line architectures represent one area of sof...

community detection is a task of fundamental importance in social network analysis. community structures enable us to discover the hidden interactions among the network entities and summarize the network information that can be applied in many applied domains such as bioinformatics, finance, e-commerce and forensic science. there exist a variety of methods for community detection based on diffe...

Introduction: In the current study, we compared h5-index provided by Google Scholar (GS), impact factor (IF) provided by web of sciences (WOS), and SCImago journal rank indicator (SJR) provided by SCOPUS for quality assessment of nuclear medicine journals. Methods: 2013 h5-index, 2012 IF, and 2011 SJR of nuclear medicine journals were extracted from their publishers namely GS, WOS, and SCOPUS....

Recent research has shown that business process models from practice suffer from several quality problems. In particular, the correctness of control flow has been analyzed for industry-scale collections of process models revealing that error ratios are surprisingly high. In the past the structuredness property has been discussed as a guideline to avoid errors, first in research on programming, ...
