Figure 2 Map of the terms selected (n = 420) from the records included (n = 1141) after searching in web of science^TM (records published in English during 1991-2013). The map was built by using the visualization of similarities approach. The terms in the title/abstract text corpus of each record were selected from 18145 terms by assuming the minimum number of term occurrences = 5; only the presence/absence of a term in a record was retained. The colors define the clusters of related items. The size of each circle is related to the number of occurrences.

Figure 3 Bibliographic coupling of authors (n = 126) from the records included (n = 1141) after searching in web of science^TM (records published in English during 1991-2013). The map was built by using the visualization of similarities approach. The selection was performed from a pool of 5017 authors, assuming the minimum number of records/author = 5. The colors define the clusters of related authors. The size of each circle is related to the number of links.
