The box-plot method was used to construct reference systems by subject category in order to study these differences and make better use of the subject category section, all the subject categories listed in the SCI JCR since are being examined, Solari and Magri , This study is still being carried out, but at least three families of subject categories can be outlined.
We chose to illustrate these three families in fields of interest to INRA fig. This figure recalls the box-plot of the frequency distribution for all journals all subject categories combined. These box-plots cannot be superposed. The second family of subject categories represented by "Plant Sciences", has group limits which are more or less equivalent to those of the total journal population.
Moreover, in this subject category, no extreme group exists. Construction of journal groups from the impact factor of all the journals in the SCI JCR 94 and journals from 3 scientific subject categories. Group in which the two journals A and B belong according to their impact factor. By introducing the notion of belonging to a journal group, these reference systems shed light on the differences between subject categories and make intra- and inter-journal subject category evaluation possible. Take as an example two studies published in two different journals.

The second is published in journal B whose impact factor is 1. Yet, in its subject category, journal A comes into the central group.

In other words, dividing journals into groups make comparison between subject categories possible, thereby avoiding misleading interpretations when just the impact factor is consulted. Take for example the Japanese journal Bioscience, Biotechnology and Biochemistry. Published since , this journal has an impact factor of 0. In the overall population, i. Position of the journal Bioscience, Biotechnology and Biochemistry within the population of journals and within the subject categories population from its impact factor. This communication will only present analysis on the impact factor.
INRA's written production for in the Institute's database of researcher's publications, comes to Determination of the group to which INRA articles belong by the impact factor of the journal in which they are published: We started by examining how the articles were spread over the reference system for the whole journal population, all subject categories combined fig.
The aim of our study was not to touch on the methodology adopted by the ISI and how citations are counted, as they have been dealt with widely in the literature e. Courtial , ; Callon et al. However, we would like to point out that the SCI JCR characterises the container the journal rather than the contents the article and its intrinsic qualities. It is true that it is the only tool of its kind and for the last 20 years has continuously and methodically gathered information on approximately scientific journals supposedly covering all subject categories. Today, very high impact factor journals are taken as references.

This use which is essentially based on isolated impact factor values has no doubt led to the over- or under-estimation of journals and in consequence of research findings and laboratories. Our rereading of the data based on the notion of belonging to a group of journals enables fuller more nuanced judgements to be made on journals. Our reference systems could be used in processes of evaluation that are based on scientific journals.

When one document A mentions or refers to another document B , the latter has been cited by the former as a source of information, as support for a point of view, as authority for a statement of fact, etc. The term "citation" is used to indicate not only the fact that document B has been cited in a reference of document A, but also the description of document B contained in the reference. In this sense, citation and reference are frequently used interchangeably.
The immediacy index of journal X would be calculated by dividing the number of all current citations of current source items published in journal X by the total number of articles journal X published that year The JCR impact factor is basically a ratio between citations and recent citable items published. Thus, the impact factor of Journal X would be calculated by dividing the number of all current citations of source items published in Journal X during the two previous years by the number of articles Journal X published in those two years Source item generally refers to an item published in any journals processed for coverage in a citation index.
In the JCR, however, only original research articles, review articles are counted for all listed journals. In the JCR a source journal is a citing journal.
