CWSI Workshop 2022

3rd Connected World/Web & Semantic Interoperability Workshop – 7 November 2022

Paper Deadline Extended until 28 September

A Connected World/Web of Things is an emerging area that not only requires development of infrastructure but also deployment of new data services capable of supporting multiple, scalable (cloud-based) and interoperable (cross-systems and cross-domain) applications.

In the race of designing the Connected World/Web as part of the Future Internet architecture, academia and Information and Communication Technology (ICT) industry communities have realized that a common problem to be tackled is the interoperability of the data and their availability for providing information services.

Worldwide there is an increasingly focusing on how to evolve communications technologies to enable a Connected World, thus Semantic-enabled Web of Things systems will need to interact and be interconnected for offering the always-promoted everything-connected interoperability paradigm.

The Connected World/Web & Semantic Interoperability workshop provides to developers, scientific researchers, industry experts and general audience interested in the evolution of the Internet of connected things world, the possibility to explore interoperability research challenges and provide a room to expose their research scientific ideas and progress and also explore new trends and opportunities of using semantic web technologies for solving problems and creating new solutions on emerging specialized paradigms like the current Internet of connected Things or simply acknowledge as Internet of Things (IoT).

Workshop Topics

In this emergent Connected World/Web of Things dynamic environment, where technology evolves rapidly and thus data sources change formats at all the time, there is a strong requirement to integrate multiple information sets. This describes the necessity to be interoperable at the data/event level so that it becomes easier to combine/aggregate data/event coming from heterogeneous data sources. This raises also the challenge of being able to look up/discover data source and relevant data.

Semantic Web has been identified as one of the most popular methods and technologies that in combination with communication services enlighten the convergence and interoperability. However, there are yet gaps to ensure semantic interoperability in a Connected World also to ensure cross-domain interworking: Healthcare, Wellbeing, Smart Ageing, Smart Cities, Agriculture, and Industrial Internet.

Relevant related topics for this workshop include, but are not limited to:

• Semantic/non-semantic methods, models, and formats for interoperability,
• Linked Data approaches for World/Web of Connected Things data integration,
• Information frameworks/systems and models for data exchange,
• Knowledge representation and connected World/Web domain models.
• Architectural building blocks and their ability to be integrated into multi-tiered systems
• Cross-domain semantics and cross-domain Interoperability models
• Design and development of Connected World/Web of Things systems;
• Data analytics for Connected World/Web of Things applications;
• Streaming data integration and complex events processing;
• Sensor data management, actuation and smart behaviour;
• Security/privacy/trust in a Connected World/Web of Things;
• Supporting web of things implementations with semantic web technologies;
• Marketplaces for semantic/non-semantic interoperable systems, applications and services;
• Use-cases and implemented applications demonstrators and proof of concepts;
• Alignment between different description models for Services/Resources/Entities;
• Standardization, Communities and Initiatives;

The above list is not exhaustive, and we would like to encourage participants to be creative.

i3-MARKET Workshop: The Price of Data 14 July

The Price of Data - Workshop with experts from i3-MARKET and EUHubs4Data

Why join the Workshop?

This workshop will enable companies to understand better how to determine the value of data and data sets when attempting to buy or sell on data marketplaces. This will be done by looking at how companies can access data marketplaces and then hosting an interactive session to determine how such platforms arrive at values for data exchanges. Through this, participants will learn how they can price their data and develop new business models. To complement this, the audience will be introduced to the training resources available through the EUHubs4Data Federation support catalogue, which helps companies develop new business models, price data and establish data exchanges.

Description of the Workshop

With data being described as the “new oil”, how can SMEs correctly value and price their data to create new revenue streams and business models to take advantage of the new data economy? Understanding the value of the data you produce can be a complex process, as the standard factors to determine pricing may no longer apply when valuing data.

Establishing new business and pricing models for your data is one way companies can benefit from Europe’s data economy, but creating new models can be difficult without understanding the market.

In this workshop, the business and data experts (from the Athens University of Economics) and training professionals from the KNOW CENTRE Digital Innovation Hub (part of the EUHubs4Data project) will help SMEs to understand how they can put a value on their data and begin to trade in the data economy, through an interactive session that explains the process of creating a business model for data exchanges.

The i3-MARKET presenters, the Athens University of Economics and Business, will explain how SMEs access European data markets (using the example of i3-MARKET technology) and how they intend to price data exchanges on the platform, based upon your input of how your company operates and trades data. This interactive session will also allow you to better understand the value of the data you have generated so that you can begin to price your data appropriately.

Following this session, KNOW CENTER, one of the Digital Innovation Hubs in the EUHubs4Data DIH Federation, will explain the resources available within the Federation to help SMEs develop new business models and better understand how they can take advantage of their data, and join Europe’s data economy.

Using Big Data and Data Marketplaces to power Digital Transformation for European SMEs

Using Big Data and Data Marketplaces to power
Digital Transformation for European SMEs

i3-MARKET organised a workshop at the 2022 Data Week, on 3rd June, between 12.00 and 14.00 CEST.

The workshop demonstrated to SMEs how the i3-MARKET Backplane will enable them to access a vastly greater marketplace of data, both for sourcing new datasets and providing their own datasets on European marketplaces. This was done through an examination of the existing business models, opportunities and challenges that SMEs encounter with European data and data marketplaces, and using the i3-MARKET Backplane as a possible tool to improve that access. The system was briefly demonstrated to show how they could use it themselves.

The Workshop was divided in three short sections: the first section was a panel debate, where experts discussed how SMEs could benefit from new digital technologies and the challenges of adopting new technologies and tools, and whether they are properly designed for SMEs to take advantage of.

The second section looked more in depth at the i3-MARKET backplane, including how the design processes attempted to make the tool as SME friendly as possible, and demonstrated the backplane in action with the results of our industrial pilots.

The final section engaged the audience via a feedback session to discuss their experiences and user stories with regard to data sharing and using data marketplaces and to discuss new business models that can be derived through the expanding data economy.

SME Forum Report: Understanding the Needs of Data Users and Data Owners

SME Forum Report: Understanding the Needs of Data Users and Data Owners

On 31 January, i3-MARKET hosted an SME Forum with members of the European DIGITAL SME Alliance, to hear their thoughts and feedback on how they currently use data and data marketplaces, with the purpose of using this information to help develop the i3-MARKET backplane to better serve the needs of European SMEs. 45 people took part in the Forum, which began with presentations from the i3-MARKET coordinator to introduce the current European landscape for data marketplaces and the benefits that greater data sharing would have for the European data economy. After providing this high-level overview, i3-MARKET technical partners then demonstrated the backplane technology that the project is developing, highlighting how this could be used by European companies to access multiple data marketplaces across a range of sectors.

Following these presentations, the participants were divided into thematic breakout sessions to discuss in more detail their experiences and motivations for using data marketplaces with i3-MARKET partners. From these discussions, i3-MARKET was able to understand several important factors that can help inform the development of the backplane to ensure that it suits the needs of its users.

One key takeaway from the Forum was that there was a stark divide between the participants in attendance as to how much time they would be willing to spend to connect to the Backplane, as some would be willing to invest more than two weeks to onboard, while others would only want to spend less than two days – and the split of participants was nearly 50/50 along this divide. This contrast could be interpreted in a number of ways, but this would suggest that perhaps some companies are still struggling to find value through data marketplaces and therefore don’t see them as a something worth investing time in. In this breakout room, the split between data providers and data consumers was also nearly 50/50, highlighting two of the key audiences that the project can engage with, and potentially form the basis of future Forums or workshop. It would be interesting to investigate further whether there is alignment between company role (data provider/data consumer) with regard to the Backplane and their willingness to invest time into onboarding, as this could reveal motivations for companies engaging with the Backplane. It did appear from initial discussions that data providers were willing to spend time onboarding, and data consumers not as interested.

The second takeaway from the meeting is that companies were interested to understand further how the Backplane could impact their business models. There were several comments regarding the incentives to use the Backplane and how i3-MARKET conceptualised transactions. Timoleon presented the i3-MARKET business models, highlighting where value could be derived for the users of the Backplane.

There was also discussion regarding the value proposition of the Backplane for SMEs, which can be considered at two levels: firstly, the practical, felt benefits of integrating with an ecosystem of data marketplaces: i.e being able to find already sorted/indexed data, more markets for data providers to sell to, greater ease-of-use for buyers, easier to source relevant data for testing new applications; and secondly, higher level, more abstract benefits, that potentially relate to the develop of the data economy, such as development of new innovations and the creation of new business models around data sharing. While it can be quite easy for the project to demonstrate how the Backplane will provide the practical benefits for companies, the conversation around the abstract level benefits – which may be required to convince non-data user companies to begin using data in their business practices, may need development, and in this, i3-MARKET is perhaps only one voice among many.

To complement this, it was agreed that the status of the Backplane as a non-profit technology based on an open-source approach was a positive indicator.

The Forum also helped the project partners identify some challenges that companies will face when adopting the backplane. Trust in the sources of data was raised as a particular concern, as users would like to be sure of the accuracy and legitimacy of the data that they will be receiving. Ensuring user trust in the system can be achieved through greater communication of the privacy, trust and security design features of the backplane. The sharing of data was also discussed, as consent would be needed from data owners before sharing their data across different platforms.

Further to this, there was interest in the anonymisation techniques that would be used and whether these could result in loss of information when transferring data. Another challenge that was raised was the supply of data for the platform. The access to large amount of data that the Backplane provides is a pull factor for SMEs to use the platform and in the World Café session there was interest in understanding the onboarding process for big data suppliers to ensure that there was a strong supply of data for companies to access.

The challenges of different data models and how companies would like to access data was raised by ATOS during this session, but it appears that there was no consensus on the type of data standardisation that would be preferred by companies. This could be explored further in a follow up meeting, as enabling ease-of-access is a good value proposition for the backplane. Another issue that was raised was how

Thanks to the hard work of partners in preparing an interesting and relevant workshop and the attendees for sharing their thoughts, experiences and opinions, i3-MARKET was able to host an informative and engaging SME Forum that will contribute to the design of the Backplane and hopefully its adoption by SMEs looking to benefit from greater access to data. The Forum provided some clear insights into the value of the platform, as well as highlighting areas in which the consortium needs to deal with challenges. Given the diversity of companies that took part in the forum, there are many avenues that can be explored in the future for further requirements gathering, including organising workshops by user type and offering more practical onboarding services for the companies that are already interested in using the backplane.

DigitalAroundTheWorld event report

DigitalAroundTheWorld event report

On 21 October 2020, i3-MARKET contributed to the DigitalAroundTheWorld conference with an experts’ panel on «Bringing the Data Platforms Perspective in IoT». Seven experts among the i3-MARKET partners were panellists in the session: Martin Serrano, Carolin Rubner, Septimiu Nechifor, Tomas Pariente Lobo, Bruno Michel, Jean-Loup Dépinay, and Cinzia Rubattino. They presented different perspectives on the evolution of Digital transformation and the role Data/AI/IoT technologies have played influencing it. The partners focused on four application areas of the project: Automotive Industry, Industrial IoT, Intelligent Manufacturing and Smart Health / Active Healthy Aging.

In-house data is not enough for many organizations embarked in Digital Transformation. On the other hand, there is a clear trend towards capitalizing data via data platforms or data marketplaces. Tomás Pariente Lobo, from Atos, presented existing data sharing initiatives and data marketplaces and the need to federate these efforts. Therefore, i3-MARKET is working on simplifying access to multiple marketplaces.

Carolin Rubner, from Siemens AG, presented data platforms and marketplaces for intelligent manufacturing. Indeed, data platforms and marketplaces for sharing or trading data assets in intelligent manufacturing ecosystems need to be based on trust. Therefore, future i3-MARKET solutions need to integrate trust-enabling properties such as openness and fairness, security and privacy, consensus-based ruling, and non-centralized control to make these marketplaces successful.

Jean-Loup Dépinay, from Idemia, then explained that Data Markets need to ensure security of transactions and enforcement of users’ privacy, as well as new ways to control accounting, governance, identity and transactions. Therefore, i3-MARKET is proposing to base this control on a tamper-proof ledger (to register transactions), consensus-based governance (every changes approved by all nodes), and cryptographic keys (all transaction signed). Through a hardware wallet embedded in a card or a SIM card, we will target to enable this control for every users in a smooth way in their personal environment using smartphones.

Finally, Bruno Michel, from IBM, focused on the Smart Health sector. The COVID-19 pandemic triggered an e-Health upsurge, due to overloaded health systems and infection risks posed by doctor visits or caregiver visits to support for elderly living independently.
To maximize usefulness and versatility of e-Health systems, monitoring needs to be coupled with artificial intelligence. In this aspect, human centric sensing and computing promotes moving intelligence to data and not data to intelligence, as well as the use of federated learning on local data. However, both approaches as well as use of simulated data can ease increasing constraints due to privacy legislation.
