Scope

Throughout its history, the IBM Systems Journal has been devoted to software, software systems, and services, focusing on concepts, architectures, and the uses of software. Peer-reviewed scholarly technical papers are published on software design, engineering, testing, implementation, and performance. Subjects covered range from programming code and algorithms, to applications, middleware, and entire software systems. The complexity and interdependence of technology in modern information systems is such that it became appropriate to merge the IBM Journal of Research and Development and the IBM Systems Journal, and this began in 2009.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

External Cites per Doc

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
