Fuente: Wipo "digitalization" In some implementations, a device displays supplemental information in connection with a digital work. The supplemental information may include a visual representation that represents one or more occurrences of an object in the digital work. The visual representation may include an area representative of an expanse of the digital work. At least one marking is located in the area in correlation to a location of an occurrence of the object in the digital work. In some examples, the visual representation may include a plurality of markings representing multiple occurrences of the object in the digital work, with a first or leftmost marking positioned in the area in proportion to a first occurrence of the object in the digital work. A second or rightmost marking may be positioned in the area in proportion to a final occurrence of the object in the digital work.
