publication counts different between citespace and WOS

[lei]

Hi, Prof.Chen and all citespace users

When I count the publication numbers of one journal<journal of="" geodesy="">, I find it is not the same between WOS analysis and the citespace. </journal>

For example:
This is from WOS website:
作者 记录 % of 1969 TEUNISSEN PJG 58 2.946 SCHUH H 54 2.743 FEATHERSTONE WE 40 2.031 SJOBERG LE 37 1.879 GRAFAREND EW 36 1.828 BEUTLER G 32 1.625 KLEES R 32 1.625 JAGGI A 30 1.524 DACH R 28 1.422 HEINKELMANN R 27 1.371 HUGENTOBLER U 27 1.371 KUSCHE J 27 1.371 GE MR 24 1.219 HIRT C 24 1.219 STEIGENBERGER P 24 1.219 YUAN YB 24 1.219

Could you explain the reason?
Thanks

Sorry for the chaos format.

Just one simpler example:
In WOS, author TEUNISSEN PJG has 58 publications.
In Citespace author TEUNISSEN PJG has 21.

OK..
I found the reason. I need to use the name alias.
Thanks!

It is also possible if your search result is not comprehensive, which is usually the case. If an author has been cited by N records on WoS, but your query only covers a subset of the N records, then there is no way for CiteSpace to find more than the citations made in the subset.

[Md. Mahiuddin Sabbir]

Dear Dr Chen,

I agree with your explanation. But in my case (when running bibliographic coupling with -1 link retaining factor and look back years) for a particular paper, published in 1974, WoS shows 353 citations, whereas citespace shows just 1 citation.

Also, this paper particularly did not show enough impact when I ran DCA. I guess something is wrong with my calculation?

Could you explain the reason?

Thanks.

[Chaomei Chen]

First of all, the question is how many of the 353 articles that cite your 1974 paper are included in your dataset. They may not be captured by your initial search.
Second, the node type makes a big difference, which means whether you treat this particular paper as 1) a citing article or 2) a cited reference. For 1), you should use bibliographic coupling, but for 2) you need to use DCA.

[Md. Mahiuddin Sabbir]

I got your points, Dr. But, I guess the problem is not with the dataset as I ran the data in VOSviewer, and it shows 345 citation counts for 1974 paper.

Would it be possible that I send you the dataset that includes a total 137 record, and you run the DCA and bibliographic coupling to find the actual problem?

Thanks!

[Chaomei Chen]

A 137-record dataset cannot possibly contain 345 citing articles. What CiteSpace shows you is the actual count based on your dataset. If you want to see the total citations on WoS, you can do that in CiteSpace by using the WoS button. I suggest you check the record of the 1974 paper in your dataset and search for the TC value, it should be 345, which would explain why VOSviewer shows you that. In other words, it would explain it if VOSviewer does not calculate the value based on your dataset; instead, it simply uses the value of the TC field. How can you get 345 citation counts if you only have 137 records to work with? I suggest you slow down and make sure you understand these points and, more importantly, basic concepts. Otherwise, you may misinterpret what you see, which is not anybody wants.

Hello Lei,

Would you please explain how to use the name alias?

Thanks.

[lei]

Hi Md. Mahiuddin Sabbir
The name alias could be useful when the names of the same author are not uniform in WOS database. This is usually related to the name abbreviation or reverse of first and second name.

In such case, you can right click name grid and set add to alias list(primary), and the nu-uniform name as add to alias list(secondary).

Then re-run the Go.

[Md. Mahiuddin Sabbir]

Many thanks, Lei.
