reports, deliverables, research notes, scientific publications and much more about the technical development of the helios platform

helios envisions the development of a highly modular platform with a robust core guaranteeing decentralised, privacy, blockchain, monetisation, 3D, VR/AR, and other features where developers can create their own social media apps or develop new modules for extended capabilities. We encourage developers to create most functionality to modules and leave only a minimal set to the app itself. Thus, other developers can benefit from the effort and participate to maintain the modules. As an analogy to such crowdsourcing is Thingiverse in which different designers share their 3D models, or WordPress where different types of users get the best of the ecosystem for the creation of websites, templates, API’s, etc.

helios has reached a main milestone with the development of the Alpha Release of the platform ensuring the interoperability and joint functionality among the core and different modules and components. This version extends the MVP and includes new functionalities such as content detection and improved user profiling.

D1.1 – Data Management Plan, initial version Download This document is the initial version of HELIOS Data Management Plan, including a description of the technical and organisational measures that will be implemented to safeguard the rights and freedoms of the research participants, possible consequences of profiling, and how their fundamental rights will be safeguarded, and how the data subjects will be informed of any possible existence of the profiling or data breaches. The Data Management Plan will provide a better understanding of the data produced, establish mechanism on how shared data will be exchanged and stored and secured with the collaboration tools of the project and what data will be publicly available and how. Not all research data will be openly accessible: Specifically, no such data that can be considered personal data will be published until this initial version is updated with further instructions. This document addresses how the data published by HELIOS will follow FAIR principles – findable, accessible, interoperable and re-usable – including what data the project will generate, whether and how it will be made accessible for verification and re-use, and how it will be curated and preserved. This document will be updated during the project as D1.2 in M18 and D1.3 in M28.

D2.10 – Recruitment and Informed Consent Procedures, H2.1, H2.2DownloadEthics is a vital part of research for all projects funded by the European Union. The HELIOS project will carry out research involving work with human beings and will generate data; therefore, ethical procedures need to be followed. Despite the project will avoid interaction with vulnerable groups, it is important to go over all the procedures when interacting with users, to assess the best way to recruit and involve them into the project activities from an ethical responsible perspective, and also to protect their data. As already mentioned, no vulnerable groups will be involved in the project, still many languages are spoken in Europe, and to guarantee full understanding of all the ethical requirements information, translation into the language of the end user will be guaranteed in different steps. These are some of the profiles that will be involved in the project for testing purposes: Teachers and students, Artists, Scientists, and Journalism professionals.
D3.2 – Final system architecture and API specificationNot available until M18 
D3.4 – Core Release VersionNot available until M24 
D4.1 – Heterogeneous Social Network Graph topology and lifecycleDownloadThis deliverable presents the description of the Heterogeneous Social Graph topology and the lifecycle of the topology. The document describes what the Heterogeneous Social Network Graph is and the local knowledge of the network each node has. The document introduces the local structure of each user, namely Contextual Ego Network, which is a multi-layer network where each layer represents a specific context of the use, and - is implemented by exploiting the ego network social model. The document provides an overview of how a user is identified in the HELIOS social network by introducing the main characteristics of the user profile, and how trust affects the lifecycle of the Contextual Ego Network structure of each user.
D4.2 – Time-dependent Social GraphDownloadThis deliverable presents the modelling of the Heterogeneous Social Graph using a temporal network and describes what the Heterogeneous Social Network Graph is and the importance to model it is using a graph formalism that includes the temporal complexity. Furthermore, introduces the Contextual Ego Network as the local view of each user of the whole Social Overlay. Thanks to the Contextual Ego Network, each user has to maintain information that is local instead of the whole graph, and the Social Overlay is maintained by the means of the union of each local view. The Contextual Ego Network is a multi-layer network where each layer represents a specific context of the user, and each layer is modelled by exploiting the ego network social model. The document moreover provides an overview of some possible studies that can be carried out on each layer, with a special focus on the usage of Graph Neural Networks.

D6.1 – Integration strategy and planningDownload

This deliverable presents the first and preliminary version of the HELIOS project integration plan.

The HELIOS consortium will provide new and updated versions of the HELIOS integration activities in the further documents belonging to the WP6. The document describes the first and preliminary integration approach that will be followed during the project as well as the code version control repository, the staging infrastructure and the tools for supporting the continuous development, integration and operation of the HELIOS Social Network. In the first project phase, the consortium will rely on a private GitLab repository managed by ATOS. At M18 the consortium plans to move the HELIOS code to a public GitHub code repository. Finally, a short description of the main components belonging to the HELIOS architecture together with the preliminary calendar for their integration is also described in the document.

D7.1 – Validation operation planDownloadThis deliverable is part of the work performed in WP7- Piloting, Validation and Evaluation. More precisely, it describes the coordination procedures conducted within task 7.1 - Coordination through the first months of the project (M4-M8, so far). The main objective of this task is to coordinate all activities within HELIOS related to the validation of the services, features, technological developments generated in WP3, WP4 and WP5 and integrated into WP6. With this purpose, it has been defined a structure of procedures and resources to coordinate HELIOS partners and external actors (i.e. entities and communities of users) that will be involved in the preparation, execution and validation activities to be performed during the project.
