Is there any alternative company tracking the impact factor of novel journals before the 5-years? Does the novel journals know their expected impact factor ahead of time?
I think it started in 2008, as it is presented in the Wikipedia site.

And according to this site, it seems new owner (The buyers are private equity funds affiliated with Toronto-based Onex Corp. and Baring Private Equity Asia) for the web of science are there since July 11, 2016
On July 11, 2016, Thomson Reuters announced that it is selling its science and intellectual property division for US$3.55 billion in cash to a pair of private equity fund managers. The division employs 4,100 people in 75 offices in 40 countries, with a headquarters in Philadelphia. The buyers are private equity funds affiliated with Toronto-based Onex Corp. and Baring Private Equity Asia
Yes, check the above reference cited by Muayyad.
The impact factor for a journal is calculated based on a three-year period, and can be considered to be the average number of times published papers are cited up to two years after publication. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones.

Yes. Impact factor for a period (e.g., 2yr, 5yr etc.) can be estimated ahead of the publication of Thomson Reuters Journal Citation Report (usually published in June-July every year).
You can estimate journal-wise, based on number of citation received last year of all publications (published in previous 2yr or 5yr period respectively) divided by total number of citable documents published by that particular journal during that period.
You can check it in Web of Science in the month of January-February. You can extract approximate figure from SCOPUS also. However pls. remember estimated result will be approximate (~10% deviation from estimation based on Web of Science, and up to 20% deviation from Scopus result is possible).
Reputed journals also track their citation. They know their approximate impact factor 5-6 month ahead of publication of Journal Citation Report.
Hi,
Before the journal's impact factor is published, you may calculate it from the Science Citation Index data, for 2 or 5 years' period. I did this once when I sent an article to a journal that was not included in JCR and did not have an impact factor yet, but I wished to see its chances for having IF in the near future, so I estimated its impact by dividing the the citations received during 2014 by the number of papers appearing during 2012 and 2013. Few months later the journal had an IF and was included in JCR.
