"VOSviewer [4] is a computer program developed for bibliometric mapping and it is based on a new method for visualizing similarities between objects called VOS (visualization of similarities). Borrowing an idea from [1], the aim of this paper is to extend the applications of the program, finding a way to describe the similarities between response patterns in the Rasch model. The similarity index proposed considers three different points of view: we can consider a response pattern more or less similar to another looking at the co-occurrences between the responses given, the difference between their total scores and the \u201Cdistance\u201D between their probabilities. Combining these three ideas in a single formula we may find an interesting way to explain the data and to visualize it in a clear and effective way with VOSviewer."@en . "[8BD601BF7D6C]" . . "5"^^ .
