Paper on metrics fluctuation accepted at Information and Software Technology

We are glad to announce that our paper “Software Metrics Fluctuation: A Property for Assisting the Metric Selection Process” (E. M. Arvanitou, A. Ampatzoglou, A. Chatzigeorgiou and P. Avgeriou) has been accepted for publication at the Information and Software Technology journal.

The paper is the result of collaboration between the University of Groningen and University of Macedonia. The paper introduces the Software Metric Fluctuation (SMF) property, which quantifies the degree to which a metric score varies, due to changes occurring between successive system’s versions

Paper accepted at Information and Software Technology

We are glad to announce that our paper “Studying the Evolution of PHP Web Applications” (T. Amanatidis and A. Chatzigeorgiou) has been accepted for publication at the Information and Software Technology journal and is now available online

Highlights

• We have analyzed the evolution of 30 PHP Web applications.
• First study on Lehman’s laws of software evolution for web applications.
• Laws implying continuous growth and maintenance are confirmed.
• However, laws implying increase of complexity and rapid decrease of the growth rate are not confirmed.
