A Data Mining Study of Sindec Complaints in the Period 2013-2017

“…The possible data mining operations will depend on the data to be processed, and if they have an attribute that defines the result obtained for the data (called class or target). For example, in text clustering there is usually no target attribute, and the initial goal is to cluster texts so that similar documents belong to the clusters [Jo et al 2017].…”

“…For text data, some of the standard pre-processing include the removal of accents and non-graphic characters. It may also be necessary to remove punctuation and adjust letter case [Jo et al 2017]. Text data may also represent categories, and in some cases, it may be necessary to structure text data as numeric data.…”

Mapping a Research Field: Analyzing the Research Fronts in an Emerging Discipline

“…Wordclouds are used mostly to visualize a data set collected from surveys or forms. Among its advantages are: (a) its ability to abstract towards the essential, identifying and grouping existing patterns in writing [10], (b) they help to provide a general sense of the text (the same visceral response does not occur when looking at a text page) through the analysis of sentiment [14], (c) they provide a quick response on possible topics of interest and research for their community [15], (d) the visual representation of data generates impact among the audience, stimulating more questions than answers, and (e) they allow to share the results of the research in a way that does not require a deep understanding of the technicalities. Its link with the bibliometric analysis can be established considering the keywords field as the set of data collected from users (researchers) in a form (submit manuscript).…”
