Consent through the lens of semantics: state of the art survey and best practices
No full textThe acceptance of the GDPR legislation in 2018 started a new technological shift towards achieving transparency. GDPR put focus on the concept of informed consent applicable for data processing, which led to an increase of the responsibilities regarding data sharing for both end users and companies. This paper presents a literature survey of existing solutions that use semantic technology for implementing consent. The main focus is on ontologies, how they are used for consent representation and for consent management in combination with other technologies such as blockchain. We also focus on visualisation solutions aimed at improving individuals’ consent comprehension. Finally, based on the overviewed state of the art we propose best practices for consent implementation
Relevant Research Questions For Decentralised (Personal) Data Governance
No full textProtecting and preserving individuals’ personal data is a legal obligation set out by the European Union’s General Data Protection Regulation (GDPR). However, the process of implementing data governance to support that, in a decentralised ecosystem, is still vague. Motivated by the need for lawful decentralised data processing, this paper outlines several relevant questions from legal, privacy and technology standpoints that need to be consideredDesign for Sustainabilit
Me want cookie! Towards automated and transparent data governance on the Web
No full textThis paper presents a sociotechnical vision for managing personal data, including cookies, within Web browsers. We first present our vision for a future of semi-automated data governance on the Web, using policy languages to describe data terms of use, and having browsers act on behalf of users to enact policy-based controls. Then, we present an overview of the technical research required to prove that existing policy languages express a sufficient range of concepts for describing cookie policies on the Web today. We view this work as a stepping stone towards a future of semi-automated data governance at Web-scale, which in the long term will also be used by next-generation Web technologies such as Web agents and Solid
Comparison of notice requirements for consent between ISO/IEC 29184:2020 and GDPR
No full textThis article analyses the ISO/IEC 29184:2020 standard and compares its requirements for notice and consent with those specified by the General Data Protection Regulation (GDPR). More specifically, it considers the extent to which the ISO/IEC 29184 standard can be applied to demonstrate compliance with the requirements of the GDPR, and to identify the additional requirements in areas where it is not sufficient. The article concludes with remarks on the potential role of ISO/IEC 29184 as a certification mechanism under GDPR for consent and notice
A model for contextual data sharing in smartphone applications
No full textThe advent of smartphones as a computing device has resulted in a shift in focus towards the design and development of smartphone applications or apps, that allow the user to complete a wide range of tasks on their devices. The users depend on apps installed on their smartphones to access services such as emails, photos, music, browsing, messaging and telephony. However, the overall user experience is disjointed as users are required to use multiple apps to complete a task where each app requires the user to enter the same information as the apps cannot share the data contextually.
This thesis investigates how smartphone apps can perform contextual data sharing with an emphasis on practical integration into the existing platforms and app models. The identification of information and its associated context is necessary to create context definitions that allow different apps to identify the context of the shared data. An approach to model the Context Definitions using computer science concepts such as object-oriented data structures provides flexibility. A context datastore is defined to store and share contextual information between apps, which creates an independence between apps for acquiring information and provides compatibility with the existing security models on various platforms. The model allows apps to retrieve contextual data in a simple and efficient manner without interacting directly with the other apps.
This thesis explains the author's hypothesis of creating contextual services in apps based on the availability of contextual information on a smartphone device. An implementation of the model proving the hypothesis is presented on Android using native tools and technologies available on the platform. The demonstration aims to show the viability of the model through use cases, evaluations and performance metrics.
Finally, the author provides recommendation for developers in adoption of the model, and the efforts required to integrate the implementation into existing platforms and apps. Further research avenues are identified that define the future of research in this area
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
