Our final goal is to investigate if and how the list of ranked words (using entropy) can be useful in other more practical contexts, such as information retrieval task or automatic classification of bio-medical textual data. In this work, we analyze the effectiveness of the keywords selected by the Montemurro's approach to capture the semantics behind biomedical text collections, and using the spectrum of words we offer a visual representation of the text's content. Besides, we compare the resulting keyword lists with the ones obtained with TF-IDF measure, and discuss some of the most interesting facts obtained from this comparison.
