Communications of the ACM is the leading print and online publication for the computing and information technology fields. Read by computing's leading professionals worldwide, Communications is recognized as the most trusted and knowledgeable source of industry information for today’s computing professional. Following the traditions of the Communications print magazine, which each month brings its readership of over 100,000 ACM members in-depth coverage of emerging areas of computer science, new trends in information technology, and practical applications, the Communications website brings topical and informative news and material to computing professionals each business day. ACM's membership includes the IT industry's most respected leaders and decision makers. Industry leaders have for more than 50 years used the monthly Communications of the ACM magazine as a platform to present and debate various technology implications, public policies, engineering challenges, and market trends. The Communications website continues that practice.

Impact Factor

The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. In other words, the impact factor of 2020 is the average of the number of cited publications divided by the citable publications of a journal. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Normally, journals with higher impact factors are often deemed to have more influence than those with lower ones. However, the science community has also noted that review articles typically are more citable than research articles.

Other Journal Impact Indicator

Any journal impact factor or scientometric indicator alone will not give you the full picture of a science journal. That’s why every year, scholars review current metrics to improve upon them and sometimes come up with new ones. There are also other factors to sider for example, H-Index, Self-Citation Ratio, SJR (SCImago Journal Rank Indicator) and SNIP (Source Normalized Impact per Paper). Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications


Communications of the ACM

SCImago Journal Rank (SJR)

SCImago Journal Rank (SJR indicator) is a measure of scientific influence of scholarly 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.
