| Resumo: | In the current scenario of economic hardship, many companies have turned to consumer
information in order to optimize the use of resources for the continuous improvement of their
services. Increasingly these organizations seek to know the wants and needs of their customers,
as well as how the overall quality of their services can be measured and influenced. The overall
objective of this work is to provide managers with a data treatment approach from user service
quality assessments. At this point, this work finds its importance and relevance when studying
consumer satisfaction and offer a means of quality analysis from the SERVQUAL scale and
the grouping of data using Kohonen's self-organizing maps. Thus, this study offers answers to
questions common to several managers, segmenting and describing groups of users according
to their answers to expectations and perception of the quality of a service. For this, the research
collected 824 electronic questionnaires with data from user quality evaluations of the Zila
Mamede Central Library, at the Federal University of Rio Grande do Norte, analyzing them
under the light of data mining tools such as classification, association, grouping and data
summarization. Four groups of respondents, identified as "Improvement", "Urgent Action",
"Adequate" and "Excess", were obtained through the crossing of Kohonen maps related to users'
perceptions and importance. Finally, this research gave the managers of the unit evaluated a
study of the responses to the questionnaire and a data treatment approach to analyze the quality
of the services offered, and also revealed interesting suggestions for future research. |
