1, Grade A and Grade I.

By SSCI, a&; Periodicals included in HCI.

SSCI and A & M human-computer interaction are important symbols to measure the level of scientific research. Academics usually think that SSCI is a&; The HCI paper is at the front.

2. Level A and Level II

CSSCI journal.

The academic level of CSSCI periodicals is recognized and respected by domestic educational circles, and it is an important data for counting the construction effect of "2 1 1 Project" and applying for key disciplines and doctoral programs at all levels. Some CSSCI journals are recognized as representative top journals in universities.

3. level a, level 3

It is an authoritative professional journal of two disciplines.

An important periodical with a level above Class B can be used as an important index for the comparison of scientific research ability of colleges and universities, doctoral dissertations, the declaration of provincial and national key disciplines, and the evaluation of teachers' senior titles, and is usually an important periodical of a certain specialty.

4. category b

Other journals included in CSSCI, as well as papers included in ISSHP, Xinhua Digest, China Social Science Digest, Guangming Daily and People's Daily, are regarded as Class B. ..

5. category c

Journals that are not included in CSSCI but included in the Outline of Chinese Core Journals have an important influence in the discipline, and most of them are journals published by young teachers in colleges and universities.

123 area:

The Division Table of China Academy of Sciences selects academic influence as the division method, and arranges all journals in various disciplines in descending order according to academic influence (3-year average IF), and divides them into four regions in turn, so that the total influence of journals in each region is the same.

The specific method is as follows:

1. Arrange the periodical collections of each discipline in descending order of 3-year average IF (the number is n), and calculate the following steps in this order.

2. The top 5% journals (5% of the total journals in this discipline, that is, 5%*n) are 1 regional journals.

3. For the remaining 95% logs, calculate the sum of their 3-year average IF (S), and then sum 1/3(S/3). The total influence of journals in the other three regions is S/3.

4. Counting from the 1 periodicals in the periodical collection in the previous step (that is, the periodical collections except those in the 1 area), IF the sum of their three-year average IF (S2) is equal to the sum calculated in the previous step (S/3), then these periodicals are periodicals in the 2 areas; Similarly, it can be divided into three journals, and the rest are all four journals (S2=S3=S4= S/3).

Extended data:

Selection of top journals:

In order to select more excellent periodicals on the basis of zoning method, top periodicals are also set up in large-scale zoning.

The selection method of top journals is as follows:

Divide the periodicals in 1 area into top-level scope; In the two years in Zone 2, the journals with the total cited frequency index in the top 10% are also included in the top periodical collection.

The definition principle of 20 15 top journals has changed, and the consideration factors of peer review have been added on the basis of the above quantitative measurement rules.

For a few journals, although they are not within the scope of the top journals classified by the above quantitative methods, they are considered as journals with high academic influence after scientific peer review, and they are directly adopted to join the top journals.
