The third paper deals with the evolution of news presentation in online newspapers, monitoring their visual progress from simple digital editions that merely served to dump content from print newspapers (rigidity) to sophisticated multi-format multimedia products with interactive features (exuberance) [34]. [PERSON], [PERSON], and [PERSON] (2021) conducted a longitudinal study on the design of online media, analyzing the front pages of five general information Spanish newspapers (elpais.com, elmundo.es, abc.es, lavanguardia.com, and elperoidico.com (accessed on 20 April 2023)) over the past 25 years (1996-2020). Further, six interviews were conducted in parallel with managers of different online media outlets. The evaluation results, combining content analysis and subjective assessment of the interviewees' responses, revealed an evolution from static and rigid layouts to dynamic, mobile, and responsive formats, displaying a balance between text and visual elements. The analysis included the language used, multimedia features, audience habits, and the degree of the offered interactions. Hence, without explicitly tackling semantic services evolution, the current work indicated presentation and functional changes in the online media frontpages, some of which are triggered by shifting to Web 3.0, while others point to the need for further semantic automations, customizations, and personalization in the upcoming Web eras, 3.0 and beyond (Contribution 3). The fourth paper focuses on collecting and processing diverse and heterogeneous information, where multimedia data can be extracted from different sources on the Web [19]. In the context of the Journalism 3.0 vision, [PERSON], [PERSON], [PERSON], [PERSON], and [PERSON] (2021) explore the possibility of creating a tool for utilizing Earth observations, i.e., to manage the massive volumes of image data, thus helping media industry professionals in the selection, usage, and dissemination of such (news) content to the public. Hence, intending to make productive satellite images for professionals who are not familiar with image processing (as other related tools require), a novel platform is implemented to automate some of the journalistic practices, i.e., to detect and receive breaking news information early in real time (especially for events related to disasters, such as floods and fires) to retrieve and collect Earth observation images for a certain event and to automatically compose personalized articles adapted to the authors' writing styles. The crafted EarthPress platform comprises the user interface, the user manager, the database manager, the breaking news detector, the data fusion, the data/image processing, the journalist profile extractor, and the software bot (EarthBot) that is responsible for the text synthesis, thus containing dominant semantic web features. Based on the conducted analysis and assessment, EarthPress represents an added-value tool, not only for professional journalists or editors in the media industry but also for freelancers and article writers who use the extracted information and data in their articles (Contribution 4). The fifth paper casts light on the semantic preprocessing of Web and Social Media informatory streams, aiming to detect breaking news events, especially those suited for drone coverage (e.g., physical disasters, such as earthquakes or storms, fire or traffic accidents, traffic jam problems, etc.) [18]. [PERSON], [PERSON], [PERSON], [PERSON], and [PERSON] (2021) elaborate on the need for news validation and documentation using piece-of-evidence material, such as visual and multimedia documents of photo/video footage. While reporters and mobile journalists can serve this requirement, a quick on-sitepresence is not always feasible due to access or distance/time difficulties that might cause unwanted delays and poor capturing quality. To face these demands, Drone Journalism (DJ) uses Unmanned Aerial Vehicles (UAVs)/drones to help journalists and news organizations capture and share breaking news stories.
