This article presents an instrument for evaluating the quality of news aggregators. For its creation, it takes as a reference the set formed by the seven Chinese news aggregators with the largest number of active users. These platforms have been studied applying heuristic evaluation and expert analysis techniques. In this way, the characteristics that give quality to these applications have been identified, formalized and operationalized through the creation of a new evaluation instrument. This instrument is presented as a checklist, characterized by the high number of quality factors that it analyses. In total, the checklist is made up of 8 parameters and 73 indicators, all of them grouped around three quality dimensions: user experience, content and business model. It is concluded that these three dimensions of quality are key to identify and understand the characteristics that, from the point of view of journalistic sustainability, make these news aggregators successful.

The growth of fake news makes users insecure when they consume information. While text-based news is perhaps the most widespread, video is gaining ground quickly, and has been transformed into informative content that can be manipulated, leading to misinformation among users. This article analyses 63 applications for mobile devices that enable the creation of deepfakes. An analysis of the apps is carried out by examining 16 indicators across three dimensions: description of the application, treatment of the image, and data protection. Each application has its peculiarities regarding the modification of the physiognomy of a person, especially their face. In some cases, the legality of the applications is questionable as they can impact people’s fundamental rights. The results demonstrate that, in many cases, the user is not informed of the technology used by the applications, nor the types of data that are collected. In conclusion the apps allow the generation of fake videos by manipulating the physiognomy of people, however, there is a lack of information surrounding the privacy policies of the data they collect. In addition, the use of these applications can damage the image and/or reputation of a person and even supplant their identity.

The SEO culture begins to penetrate newsrooms, showing that it is no longer enough to incorporate experts in content optimization (not even the creation of specialized departments) and it is necessary going one step forward. The impact of the algorithms is transforming the profile of the digital journalists, forcing them to learn SEO production, editing and publication skills, and modifying the media's own agenda setting, giving trends and topics of interest to audiences. In this article, an approach is made to Search Engine Optimization techniques with the aim of exploring, from journalism practice in the core of newsrooms, the opportunities that this emerging profile represents professionally and academically. This work is carried out in a constructive sense, the viability of journalistic companies depends largely on the traffic branch that comes from SEO, but it is also a critical warning of the consequences that these work guidelines can entail in the exercise of Journalism. In this time of disinformation and saturation, the role of media intermediaries appears more necessary than ever and, paradoxically, it is also more disputed than ever by algorithms.

The scores are musical records that have unique characteristics for their production, circulation and use. The objective of this article is to describe and reflect on the main stages of the treatment of musical scores of the collection of Coral USP. This is an exploratory-descriptive work and characterized as an experience report, which presents elements of score cataloging with reference to RDA, the MARC metadata standard, the theoretical reference about the studies about musical notation and the users' needs identified in the informational environment. The organization process of the music score library followed a strategic planning developed in three stages: 1) diagnosis; 2) training; and 3) actions. It was verified that the examples presented denote the possibility of creating descriptive records that represent the scores as documents that can be retrieved in bibliographic management systems. It is concluded that the reading of documents and the cataloging of scores require knowledge of the document structure and musical notation from the cataloger to ensure that the information needs of users are met, especially in the digital environment.

Automated fact-checking consists of automatically determining the veracity of a claim by applying existing artificial intelligence technologies to classify it into one of the categories commonly used by human fact-checkers (true, misleading, false, etc.). This paper presents the first systematic literature review in Spanish on the evolution of research on this topic. It also aims to analyze the level of accuracy of algorithmic solutions and the impact of published work, using descriptive and inferential statistical treatments (chi-square and Kruskal-Wallis tests). According to our results, the highest volume of contributions was concentrated in the last three years, mainly from the Asian region and United States. Papers proposing integrated algorithmic methods or systems predominate. Studies on linguistic models, which still have several limitations and below-average effectiveness, are in the majority. There is little attention to models based on image analysis, and the presence of fake audio detection algorithms is practically nonexistent. In line with previous work, our study concludes that there are no statistically significant differences in the level of accuracy of the diverse algorithmic models proposed, despite their different degrees of technical complexity.

Recognizing and avoiding the impact of fake news in electoral times is an area of concern for institutions, academia and citizens because it affects the quality of democracy. Under this premise, the Ecuador Verifica coalition was created to mitigate the impact of disinformation networks, contribute to the evaluation of the veracity of political discourse, and provide citizens with tools to discern between true and false information. The purposes of the work are to share the Ecuador Verifica coalition scheme and to evaluate its work. The methodology is qualitative through case studies and semi-structured interviews. The fight against disinformation is a collective effort, Ecuador Verifica approaches it from multiple perspectives and thanks to the confluence of actors from diverse backgrounds: media, civil society and academia, although the incorporation of the private and public sectors would help diversity.

Social Media Live Television (SMLTV) is a derivation of Social Media Live Streaming (SMLS) and refers to the broadcast of content usually associated with the live television experience through social networks. The nature of interactive video also allows this type of content to facilitate audience participation and the search for sustainable experiences for content publishers. This paper studies the SMLTV broadcasts made by Facebook Watch in 63 matches of the 2020 Copa Libertadores for users of the South American social network. The results not only allow detecting the performance obtained by these publications, but also facilitate the understanding of what are the main differences between a Social Media Live Television broadcast and a conventional television broadcast when covering the same live event. All this allows us to understand how SMLTV changes and improves the way of watching television through social networks, opening opportunities for the sustainable development of this type of broadcasts for its content publishers.

Històries del Punt is a documentary, interactive and community project that aims to restore and revalue the shared memory of the working class of Mataró (Barcelona). It is conducted through the recovery and reuse of certain sources that have usually been overlooked by historians (i.e. amateur photos, images from local broadcasts, factory films and oral memory). Its aim is to build a "place of memory" for a city that came to be mostly dependent (80%) on the textile industry. Still today, the town has merely written its technological and political history. The process that gave birth to the project has led to a conception of memory from the collective sphere. We have focused on apparently minor elements that usually do not compete in History. We have rediscovered not only sources, but also unknown historical facts such as a clandestine abortion network, small-scale sabotage, solidarity networks, undeclared work, the psychology of migration, motherhood... and, above all, we have highlighted a shared material experience within the diverse working class of Mataró.

The University of Siena preserves the historical archive of the former neuropsychiatric hospital of Arezzo (1901-1990) with the aim of conserving, rearranging, studying and enhancing the material (administrative, medical, audiovisual, iconographic) present therein. The article reflects on the possible "educational use" of this plurality of materials and on the need for the Archive to continue to be defined as a space for multidisciplinary research-intervention for all those subjects (especially health and care professionals) interested to know and explore the relationship between mental illness and mental hospital confinement.

El caso Grimau consistió en la detención, condena y fusilamiento de uno de los líderes comunistas más importantes de la lucha contra el franquismo infiltrado en 1962 en la España de Franco, y su correspondiente proceso judicial repleto de irregularidades gravísimas incluido un supuesto intento de suicidio. Esta noticia no hubiera tenido un impacto internacional sino hubiera sido por Radio España Independiente (REI), conocida por la opinión pública como La Pirenaica, una emisora clandestina subvencionada por la Unión Soviética. La metodología utilizada ha sido utilizar los Archivos Históricos del Partido Comunista de España, sección de guiones de Radio España Independiente, desde el siete de noviembre de 1962, día en el que Julián Grimau fue detenido, hasta el 20 de abril de 1963, cuando fue ejecutado. Un total de 164 días de emisiones consultadas. Las conclusiones más importantes son: Destacar que, a pesar de las graves irregularidades del proceso judicial y el fuerte impacto de su ejecución en la opinión pública mundial este caso no ha formado parte en la conciencia actual de la opinión pública española.
