Extraction of metadata of citations from Web Of Science #18

Closed chandryou closed 6 years ago

chandryou commented 6 years ago

I'm trying to extract citation data of clinical guidelines (currently focusing on American and European hypertension guidelines) from Web Of Science. I found that I couldn't extract whole citations of the guideline (WoS showed 615 citations, but only metadata from about 500 articles can be extracted). It is not a problem of this package, but is their anyone who have an experience like this?

As explained in the bibliometrix tutorial, WoS does not allow to download more than 500 records at time. You can download your whole collection splitting it in two files: 1) select from record 1 to 500 for the first one, then download it; 2) select from record 501 to 615 for the second one and then download it.

To import the two files in bibliometrix, please use the function readFiles: D<-readfiles("filename1.txt","filenames.txt")

Another way to import the two files in bibliometrix is to use the biblioshiny app (included in bibliometrix package). You only need to put the two WoS files into a zip file and later read it by using the loading page of biblioshiny app.

Thank you @massimoaria for answering this thread. I'd tried the exact way you explained. But I'd got only about 550 records. I couldn't figure out why...
