SCI and SSCI are very important academic databases, which can be used to query the impact factors of various journals. The impact factor represents the frequency and range of articles cited by the journal and is an important index to measure the importance of the journal. By querying the impact factors of journals, we can better understand the quality and influence of journals, and then choose the appropriate journals to contribute or quote.

To query the impact factors of journals, you need to go to official website of SCI or SSCI, and enter the journal name or ISSN (International Standard Journal Number) in the search bar to find the information of related journals. Then click on the journal name to enter the journal page, and you need to browse the impact factor data of the journal. Generally speaking, the data of impact factors are published once a year, and the rankings or evaluations of journals in different disciplines are often listed in detail.

The influence factors can't fully represent the academic value of journals. The influence factor only ranks the cited articles in a certain year, which is influenced by many factors, such as the number of articles, the cited professional fields and regions. Therefore, when choosing a periodical, we need to comprehensively consider many factors such as periodical distribution cycle, audience, academic level, popularity and so on.

The meaning of journal impact factors

The impact factor of a periodical is an index to measure its importance and academic influence. It is calculated by using the citation of papers published in this journal in a certain period, and it is one of the important indicators to judge the importance and influence of an academic journal.

The calculation period of the impact factor is two years, and the IF index refers to the sum of the cited times of all papers published in this journal in a certain year (usually in the last 12 months), divided by the total number of papers published in this journal in that year. Therefore, the higher the impact factor, the more times the papers published in this journal are cited by other academic researchers, and the higher its academic quality and influence.

Influence factors are very important for scholars and academic journals. For scholars, choosing to publish papers in journals with high impact factors can better show their academic research level, help improve their personal influence and gain more academic opportunities; For academic journals, publishing papers with high impact factors can attract more scholars' attention and improve their visibility and influence in the academic circles where high-quality papers are flooding and flowers are blooming.
