We provided 3 (three) fine-grained taxonomies for aspect-based sentiment analysis and opinion summarization applications in Portuguese. The taxonomies of fine-grained opinions (hierarchically organized aspects) contain explicit and implicit aspects extracted web reviews on smartphones, digital cameras, and books. The taxonomies are available in OWL format.
