ResearcherID is an identifying system for scientific authors. The system was introduced in January 2008 by Thomson Reuters. This unique identifier aims at solving the problem of author identification and correct attribution of works. In scientific and academic literature it is common to cite name, surname, and initials of the authors of an article. Sometimes, however, there are authors with the same name, with the same initials, or the journal misspells names, resulting in several spellings for the same authors, and different authors with the same spelling.
