The JBR offers two basic types of indicators: (a) indicators of impact and (b) indicators of bibliometric quality.
The indicators of bibliometric quality are divided into (i) basic and (ii) composite indicators.
(i) basic indicators
The basic indicator scores are primarily intended for editorial boards, to be used in shaping their editorial policies. They provide an insight into the degree of the journal's compliance with the criteria for indexing in international bibliographic databases, in particular the citation indexes WoS and Scopus.
The list and desctiption of the basic indicators are show in the following table:
code |
name and description |
LegArt |
share (%) of legitimate papers, excluding reprinted articles, conference papers |
Equip |
equipment of papers, i.e. full author affiliations, summaries/abstracts in Serbian and a foreign language, keywords in Serbian and a foreign language and acknowledgments (including funding information) |
IntLang |
share (%) of papers published in world languages, i.e. the full text of papers available in a major international language |
NRef |
average number of references per paper, not including papers without cited references |
1+ Ref |
share (%) of papers with at least one cited reference, either in the list of references, footnotes or endnotes |
JourRef |
share (%) of journal references, including local annuals and not including magazines and newspapers |
IntRef |
share (%) of international references, i.e. those published abroad in a foreign language |
AgeRef |
average age of cited references, expressed as the mean/median age in years; the so-called citing half-life |
indConc |
author concentration index, i.e. the share (%) of papers by authors affiliated with different academic institutions in the total number of papers by authors with academic affiliations |
indInt |
author internationality index, i.e. the share (%) of papers by authors affiliated with international academic institutions in the total number of papers not including papers co-authored with local authors |
The basic indicator scores are shown in the tables:
- Bibliometric quality for all evaluated journals, with their rankings for individual years,
- Bibliometric quality for the journals classified in a particular group, with their rankings for individual years, and
- Bibliometric quality on the page Journal's bibliometric portrait, where the data are displayed longitudinally, for all years when the journal was covered by the evaluation.
The basic indicator scores relevant for the impact assessment (authors' concentration index, authors' internationality index, average age of references and self-citation rate) are shown in the table Impact on the page Journal's bibliometric portrait.
(ii) composite indicators
The composite indicator scores are primarily intended for editorial boards, to use them in designing their editorial policies. They are indirectly used to check whether, and to what extent, journals meet ethical standards. The internationality is used in a direct way, as a requirement when allocating journals into the highest tier at the national level (K24). The procedure is described in some details under Journal rating.
The list and the descriptions of the composite indicators and the underlying bibliographic data (variables) are provided in the following table:

ET |
4. Transparency of editing: organizational efficiency and the transparency of editorial procedures |
Online |
online submission, peer review and tracking (using a journal management system) |
Trans |
transparency of procedures (online availability of acceptance/rejection rates and reviewers' decisions to the funding institution and the evaluator) |
I |
5. Internationality: the share of papers in English, references in international languages and papers by foreign authors |
StraAut |
share (%) of papers by international authors (not including articles co-authored with local authors) |
KoAut |
share (%) of papers co-authored between local authors and those affiliated with international institutions |
StraRef |
share (%) of international references, i.e. those published abroad in a foreign language |
EngJez |
share (%) of articles in the English language (full text in English only or both in English and Serbian) |
PQ |
6. Publishing quality: publishing and methodological rigour in applying international standards |
Starost |
average age of cited references, expressed as the mean/median age in years; the so-called citing half-life) |
BrojRef |
average number of references per article (not including articles without references) |
RadStd |
share (%) of legitimate articles (reprinted articles, conference papers and similar items are not considered legitimate) |
CasRef |
share (%) of journal references (including local annuals and not including magazines and newspapers) |
1Ref |
share (%) of articles with at least one reference (not including editorials and similar items) |
The values of individual variables are calculated using a complex analytical procedure and the corresponding weighting formulas in order to determine journals' performance according to each of the six composite indicators. The maximum composite indicator score that a journal can have is:
| code | composite indicators
|
score |
| MQ | Metadata quality: the completeness of article-level metadata in accordance with international standards |
10 |
| AI | Academic integrity: compliance with publishing, ethical and reviewing standards and procedures |
25 |
| VA | Visibility and availability: ensuring that papers are easily located and downloaded |
15 |
| ET | Transparency of editing: organizational efficiency and the transparency of editorial procedures |
20 |
| I | Internationality: the share of papers in English, references in international languages and papers by foreign authors |
20 |
| PQ | Publishing quality: publishing and methodological rigour in applying international standards |
10 |
The composite indicator scores are displayed on the page Journal's Bibliometric Portrait in Table B. composite Indicators, where they are provided for all years in which the journal was evaluated.
Finally, the scores are converted to z-values in order to show the journal's relative performance according to individual composite indicators. The determined scores are displayed in the dynamic radar chart Relative performance, in the form of the journal's profile.
The scores are also displayed in the national citation index (SCIndeks) on the page Bibliometric performance under Bibliometric quality.
