Cabell's Classification Index©
Perspective matters.
Cabell’s CCI© is a unique way to look at journal quality that considers disciplinary perspectives in assessing journal influence. The reality of journal evaluation is that research is increasingly cross-disciplinary and, accordingly, an individual journal might publish articles relevant to several fields. As such, researchers in different fields often use and value the same journal differently. For example, a top journal in computer science might sometimes publish articles about educational technology, but researchers in educational technology might not really “care” about this journal the same way that computer scientists do. Conversely, top educational technology journals likely publish some articles about computer science, but these journals are not necessarily as highly regarded by the computer science community. In short, we think that journal evaluations must be more than just a number. To better illustrate this dynamic, we must ask, “How and to whom is this journal important?”

How the CCI© helps.
To help you answer this question, we developed the CCI©, a contextual citation metric that ranks journals within each of the disciplines and topics in which it publishes. This means that a journal that publishes in both computer science and educational technology will have an influence classification for each of those two disciplines. Further, within each discipline, the CCI© classifies a journal’s influence for each topic that it covers. This gives researchers and tenure committees a way to evaluate not just how influential a journal is, but also the degree to which a journal influences different disciplines. Researchers, librarians, and tenure committees all use the CCI© to better understand how academic journals align with their objectives. Between choosing a journal for publication, managing library purchases, or evaluating faculty CVs, the CCI© gives academics the tools to understand journal evaluation dynamics.

Accessing the CCI©.
The CCI© tool is included as a part of every Cabell’s subscription; each journal result has a CCI© interface built into the journal’s details. To use it, simply click on either the CCI© thumbnail or open the journal details and scroll down until you see “Contextual Influence (CCI©) Report”. From here you can select disciplines that you are subscribed to and, by clicking on individual disciplines, view the classifications for the journal’s topics. For a more detailed explanation on using the CCI©, use the step-by-step guide found here.

How the CCI© works.
To generate the CCI©, we calculate the average citations per article for each journal from the preceding 3 year period, then put each journal into a z-score transformed distribution for each discipline and topic. This yields, for each discipline and topic that any journal publishes in, an individual ranking environment that consists only of the titles that publish therein. From there, we use the distribution to categorize each of the journals within each environment into one of three influence classifications that approximate the top 10% (Premier), 11-20% (Significant), and >20% (High). Because journals must achieve a certain threshold for citation activity to be included in the underlying citation database, any journal ranked by the CCI© is considered to exhibit a relatively high level of influence. Journals with insufficient citation activity to be included in the citation database are marked as either “Qualified” or “Novice”, depending on how long they have been publishing. Journals that are younger than 5 years old are “Novice”, likely not having been around long enough to generate significant citation activity. Other journals with no underlying citation data are marked “Qualified”.


Difficulty of Acceptance©
Choosing your outlet is as important as the research itself.
In order for your research to have real impact, it first must be seen. When the efficacy of your research and the progression of your career is at stake, maximizing the visibility of your work is a priority. But let’s face it – some journals are hard to get into and some are very hard. Cabell’s DA© is a better way for researchers to gauge a journal’s exclusivity, to highlight their own accomplishments for tenure, and to balance the need for visibility with the very real difficulties of getting accepted.

How the DA© helps.
The Cabell’s DA© rating quantifies a journal’s history of publishing articles from top performing research institutions. These institutions tend to dedicate more faculty, time, and resources towards publishing a lot and publishing well. A journal that accepts more articles from these top performing institutions will tend to expect the kind of quality or novelty that the availability of resources better facilitates. So, researchers use the DA© to find the journals with the best blend of potential visibility and manageable exclusivity.

Accessing the DA©.
The DA© is included as a part of every Cabell’s subscription; each journal with a DA© rating has it built into the journal’s details. To use it, open the journal’s details and scroll down until you see “Difficulty of Acceptance”. Here you can see the relative difficulties of acceptance for each discipline that the journal is in and that you are subscribed to.

How the DA© works.
To generate the DA©, we calculate the average number of times an article from a top performing institution publishes in each journal, then analyze them across a z-score transformed distribution for each discipline. From there, we use the distribution to categorize each of the journals into one of three difficulty classifications that approximate the top 10% (Rigorous), 11-20% (Significantly difficult), and >20% (Difficult).

Institutional Publishing Activity©
Knowing the institutional landscape.
Whether you are considering new institutions for employment or trying to keep your publishing objectives on track, the IPA© can help you make informed career decisions or better evaluate your research goals. The IPA© is an objective measure of each university’s influence in scholarly communication. Simply, the IPA© lets you know how universities stack up against each other in terms of the robustness of their research programs.

How the IPA© helps.
If you are interested in joining a university with a more research-oriented culture, consider sending your application to universities with a higher IPA©. As an administrator, you can use the IPA© to evaluate how your institution’s research program is performing compared to other institutions.

Accessing the IPA©.
IPA© ratings are included as a part of every Cabell’s subscription. To access the IPA©, find the blue search area while you are signed in to your subscription. From here, change the search to “IPA©” or “institutional publishing” and select a discipline from one that you are subscribed to and filter by other criteria. Initiating a search will then return a list of institutions and their respective IPA© ratings. For a more detailed explanation on using the IPA©, use the step-by-step guide found here.

How the IPA© works.
Faculty from institutions with a higher IPA© rating tend to publish more articles in more highly cited academic journals than those with a lower rating. This measure often indicates that an institution is willing and able to dedicate more resources toward research and publishing.
