1. Mapping co-authorships with BibExcel

2. Please get scientometrics.out from http://www8.umu.se/inforsk/Bibexcel/scientometrics.out http://www8.umu.se/inforsk/Bibexcel/scientometrics.out..and look at it in BibExcel Choose Whole string and Sort descending and then press Start

3. View the cit file, scroll and you will see some names in big letters and some with spelling variants like VANRAAN AFJ, van Raan AFJ, Van Raan A

4. To fix the problem select the out-file and run Edit outfiles/Convert Upper Lower Case/Good for author/cited author in outfile this will make a low-file

5. Select the low-file and make a new cit-file by pressing Start The new cit-file has big and small letters in last names, spaces and hyphens in last names have been removed And Vanraan AFJ has now almost twice as many papers.

6. You may now go even further by only accepting one initial. Select the low-file and run Edit out-files/Keep only author’s first initial Then the 1st-file is created. Select the 1st-file and press Start. Look! Vanraan has one additional paper and Moed got two more However, there is a potential risk that last name plus first initial might refer to two different persons

7. Note: To remove potential duplicate names select the 1st-file and choose Make new out-file and Remove Duplicates and press Start. Then use the oux-file! Then make a new cit-file based on the oux-file!

8. To make co-authorships: View the cit-file. Copy names down to 15 papers from The list, Clear the list and Paste them back to The List Select the oux-file and run Analyze/Co-occurrence/Make pairs via listbox (answer No to the first question) The coc-file has the co-occurrences
