  Automatic text analysis methods, such as Topic Modelling, are gaining much
attention in Humanities. However, scholars need to have extensive coding skills
to use such methods appropriately. The need of having this technical expertise
prevents the broad adoption of these methods in Humanities research. In this
paper, to help scholars in the Humanities to use Topic Modelling having no or
limited coding skills, we introduce MITAO, a web-based tool that allow the
definition of a visual workflow which embeds various automatic text analysis
operations and allows one to store and share both the workflow and the results
of its execution to other researchers, which enables the reproducibility of the
analysis. We present an example of an application of use of Topic Modelling
with MITAO using a collection of English abstracts of the articles published in
"Umanistica Digitale". The results returned by MITAO are shown with dynamic
web-based visualizations, which allowed us to have preliminary insights about
the evolution of the topics treated over the time in the articles published in
"Umanistica Digitale". All the results along with the defined workflows are
published and accessible for further studies.
