Directly copy/paste from
Wikipedia.
By the way people are going to research due to merit reward
. I just avoid him to report plagiarism as well he try to research.Nopes, This guy copied from that paper (the PDF reference in the post). Since I do not expect a research paper to be plagiarized, and both paper and wikipedia having same definition, I make assumption might be wikipedia is plagiarized.
PS: Still make me wonder how somebody looking for a simple definition find a complex research paper in which definition is in the third page of the research paper not even in the first and did he/she really read that paper to that point?
I also agreed with @r1s2g3 and I don't think it can be taken as plagarised contents. He/she looking for research paper before giving the answer is actually better than just posting spam. If she/he read that research paper before posting means something to me and even worth a Merit(at least for me). Since the introduction of Merit system, people are going to read even research papers before posting. So isn't that good thing rather criticizing?
I don't know why people are thinking that details in the Wikipedia is always right and those are not plagarised from anywhere. Actually some of the details are incorrect in Wikipedia and academic communities normally not taken details published in the Wikipedia as trusted sources for cites, since those details can be manipulated.
