SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Journal of Systems and Software publishes papers covering all aspects of software engineering and related hardware-software-systems issues. All articles should include a validation of the idea presented, e.g. through case studies, experiments, or systematic comparisons with other approaches already in practice. Topics of interest include, but are not limited to:
• Methods and tools for, and empirical studies on, software requirements, design, architecture, verification and validation, maintenance and evolution
• Agile, model-driven, service-oriented, open source and global software development
• Approaches for mobile, multiprocessing, real-time, distributed, cloud-based, dependable and virtualized systems
• Human factors and management concerns of software development
• Data management and big data issues of software systems
• Metrics and evaluation, data mining of software development resources
• Business and economic aspects of software development processes
The journal welcomes state-of-the-art surveys and reports of practical experience for all of these topics.
The goal of the Controversy corner is both to present information and to stimulate thought and discussion. Topics chosen for this coverage are not just traditional formal discussions of research work; they also contain ideas at the fringes of the field's "conventional wisdom". Articles in this category will succeed only to the extent that they stimulate not just thought, but action.
New Ideas and Trends Papers
New ideas, especially those related to new research trends, emerge quickly. To accommodate timely dissemination thereof, JSS introduces the New Ideas and Trends Paper (NITP). NITPs should focus on the systems/software engineering aspects of new emerging areas, including: the internet of things, big data, cloud computing, software ecosystems, cyber-physical systems, green/sustainable systems, continuous software engineering, crowdsourcing, and the like. We distinguish two types of NITPs:
- A short paper that discusses a single contribution to a specific new trend or a new idea.
- A long paper that provides a survey of a specific trend, as well as a (possibly speculative) outline of a solution.
New Ideas and Trend Papers warrant speedy publication.
