Thanks :)

Do you mean the distance between two countries in a map of a co-authorship network? In such a map, the distance between two countries approximately reflects the number of co-authored publications of the countries (after normalizing for the total number of co-authored publications of each of the two countries). In general, the closer two countries are located to each other, the larger their number of co-authored publications.

fractional counting

Thanks for the answer
but I still need some help. on the generated map we have the display of several countries. I need to know what research is related to each country. For example, Italy had 40 articles. How to generate a list with 40 articles related to Italy?

Thank you so much!

Thanks Ludo for your assistance. I have realised that the problem was specifically associated with conferences.. Articles seem to be find.

Thanks Ludo for your reply. I will try again and see what happens.

It worked, Thanks.

I also have the same problem, I already downloaded from PoP with keyword and save the result as RIS, however when a choose create a map with bibliographic data, the co-occurrence fitur was disabled. Could you give me advise about that (VosViewer 1.6.15). Thanks

Thank you for your quick response.
I am doing bibliographic coupling.
and how can we explain the mentioned information in the case of co-citation?

I thank you so much for your response. If I can ask, if axes have no meaning, and if we have item A and item B with the same distance with item C, why we can have item A above item C (in vertical distance) and item B next item C (in horizontal distance), I could understand how VOS find the distance, but how it located such items, I could not get it. I am sorry if I am missing an obvious point here.

Thank you for your kind support. "sources of primary data by country" : For example, an author published an article who is working at Harvard University which is his affiliation but he used data from Malaysia. So the source of data was Malaysia and his affiliation was Harvard. I wanna know how to find source of data using VOSviewer? or is there any other software for this purpose?

Thanks very much Ludo. I will give it a try.

Thank you for your answer ! I already use the data source Web of Science and it doesn't work... By "the data you provide as input to the software" you mean the key words I enter in the first place in the search engine?

Is it possible to use when we have about one hundred documents?

More on this issue:
Exactly the same problem when trying to run VOSviewer within web browser.
Splash image displays and then closes.
java 8 reinstalled and reverified.

Thank you so much!!! you saved me many hours of work.

Perfect, I am clear now. Thank you

I use different sources, for example, I downloaded bibliographic data of our library OPAC (Sirsy Simphony), to analysis thesis and dissertations to know the most researched topics. Or sometimes I mix information of different databases or sources from grey literature, to do a state of art

I would first like to say thank you for your reply is a much appreciated your quick response and support with this software.
It would be important that this term is included . I was thinking along the same lines I tried increasing the threshold to include all terms instead of the standard 60%. The term did appear when I did this but it still had a relatively low occurrence count compared to the individual five year period. I also tried all the other settings in regards to binary counting full counting abstract only et cetera see if it had a similar pattern and it did. Just wondering if you could help me with the command to make sure it counts this time for the combined library. Just that I'm doing this analysis for a research team and it can going to struggle to explain why the term is so prevalent in the five year periods and then when I combine the citations it disappears. Do you know why the occurrence count would be so much lower than the five year periods in both binary and full counting in the combined library compared to the 5 Years Libraries. I would assume when I combine it is not identifying all the occurrences of that term to be important not counting every one of them as it does in the five year period versions. We were planning to make a table which would count the occurrence of the term in each five year period with the idea that it should add up to the same as combined library with all years?
