I used CoPub 5.0 as my text mining tool in my research. However, I found that the number of abstract related to Alzheimer's disease and lipid metabolism retrieved by CoPub 5.0 are much more lower than PubMed. Could anyone tell me the reason ?
Thank you very much.
Since they are different tools and do different things, is there a reason that the numbers of abstracts should be the same?
Aren't they search articles using keyword entered by users? Both of them access to Medline database,so I thought that their results should be the same. Based on reply, sir, do you mean that they are using different algorithm so their results returned are sure different?
