Quality of service evaluation of a university library using text mining and Kohonen self-organizing maps
Survey data on service satisfaction of customers of a university library are analyzed. Viscovery SOMine is used to identify and exclude outliers and to form four groups of customers with high vs. low expectations and high vs. low service experience. A text analysis model is evaluated on top of the defined groups.

Text mining of medical records for radiodiagnostic decision-making
Radiology department records of children who had undergone a CT scan procedure at Nagasaki University Hospital in the year 2004 are analyzed using Viscovery SOMine. Keywords are identified with a significance value within the narratives of the medical records that could predict and thereby lower the number of unnecessary CT requests by clinicians. This method can be used to reduce overuse of medical radiation, which poses significant health risks and staggering costs, especially with regard to children.
Mining informetric data with self-organizing maps
This article describes three bibliometric models: 1) scientific performance of Latin America in the field of agriculture, 2) the visibility of Latin America in scientific journals, 3) research trends in biomedicine associated with non-linear dynamics. Viscovery SOMine is used for clustering with respect to bibliometric indices, such as number of references in different journals, number of citations and number of keywords.
