Abstract/Resumo
Topic modeling is a challenging task on its own, and when the text being analyzed is very short, the challenge increases significantly, as there are no reliable metrics to evaluate the quality of the generated topics. In this study, several experiments are conducted using different preprocessing methods and various topic modeling techniques to determine which approach produces the best results. The singularity score is also proposed as a metric to evaluate the quality of the topics created.
