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 versionDownload

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 specificationDownload

The document presents different architectural options for the overall HELIOS platform, which comprises the core, the extension modules to it, and the applications utilizing their functionalities. The architecture is generic enough to be implemented in various operating systems but the document refers to the Android operating system in some sections, as the project has selected and Android-first approach. In addition to the overall architecture, the document presents the currently planned core modules and extension modules and applications, presents the functionalities of each of them, and provides API descriptions for them. This deliverable builds upon D3.1 “Draft system architecture and basic API specification”.

Due to the iterative methodology followed in the project, the detailed architecture choices and the detailed API specifications will be updated according to inputs and feedback from the other work packages and tasks throughout the project. The APIs will be updated throughout the implementation of this architecture in the corresponding repositories of the project.

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.
D4.3 – Mining the social graphDownload

In this deliverable, we explore the state-of-the-art and new approaches for mining heterogeneous social graphs in decentralized time-evolving systems. Such approaches can discover patterns of relations and interactions driven by the underlying preferences of HELIOS users, which in turn can be used to improve the quality of HELIOS applications. In particular, we investigate existing graph mining practices, such as graph clustering and graph neural networks, which can mine the time-evolving organization and preferences of social media users and propose novel protocols and adaptations that help adopt them in the decentralized setting of HELIOS.

To this end, we propose a novel community detection protocol for discovering the community structure of decentralized networks, as well as a novel decentralized adaptation of temporal graph neural networks of mining user preferences. The latter can recommend future interactions with similarly high efficacy to their centralized counterpart in social network datasets with similar properties as those of the envisioned HELIOS networks and are deployed in a graph recommendation module that facilitates social recommendation and analysis tasks. To support the integration of that module with the rest of the HELIOS platform, we also improve the Contextual Ego Network management library.

D4.4 – Define rewarding methodologies DownloadThe purpose of this deliverable is on the one side to analyze which is the best blockchain platform where to build the Helios Rewarding system and on the other side, to define the actions to be rewardable as well as the algorithm to calculate the number of tokens to be distributed for each of the users who contributes on top of HELIOS. In order to do so, an analysis of different rewarding systems used by some of the most popular decentralized social networks has been conducted. Furthermore, different types of the blockchain (permissionless vs permissioned) are investigated. Last but not least, the HELIOS Reward System is defined taking into account use case applicability.

D4.6 – Neuro-based servicesNot available until M24 
D4.7 – Organic social graph creationNot available until M24 
D4.8 – Development of content-aware social graphsDownload

In this deliverable, we explore the development of content-based features to enrich the HELIOS Heterogeneous Social Graph (HSG), and in that way provide support for content-aware user profiling and matching services. To this end, we aggregate the image collections of the HELIOS users and extract semantic information in three complementary ways; the first focuses on analyzing the user interests, the second construct a user representation in a self-supervised way and the third relies on processing pieces of text extracted from the images.

The document provides the main principles of the dissemination and communication strategy to be adopted by all partners, with the definition of the stakeholders' group regarding their potential relationship with HELIOS.
D8.3 – Dissemination Mid-Term ReportDownload

The purpose of this deliverable is to present a report of the communications and dissemination activities that have been conducted within M1-M17 of HELIOS’ project duration, with the aim of maximizing the impact of the project and positioning it among different stakeholders such as Industry, Research Community, General Public, Developers, Media, among others. A comparative analysis of the metrics achieved so far and expected is presented in order to evaluate the effectiveness of the strategy presented on D8.1 and set the pace for future activities that will be performed in order to meet both objectives and KPI’s.

In relation to the dissemination and communication activities, the HELIOS consortium participated in a total of twenty-three (23) events and made twenty-six (26) presentations about the project reaching an estimated audience of 7580 people.

Furthermore, the website has been revamped to offer content according to the current status and progress of HELIOS especially in relation to the HELIOS platform, use cases, and validation apps. Moreover, social media accounts including Twitter and Facebook have been essential to engage with stakeholders and share the word about HELIOS. Until now we have reached 536 posts, 3.472 shares/RT’s, and 4.343 followers/likes. With regards to the dissemination and communication content, a total of ten (10) papers, one (1) press release, three (3) posters, fourteen (14) videos and three (3) newsletters have been produced in this period summarizing the project achievements for the HELIOS-targeted audience. Moreover, a leaflet and roll-up have been created to support HELIOS presence at events.
