Read the current topics on Blasting News, discuss on EUNOMIA

July 22nd, 2021 by

EUNOMIA provides a dedicated instance powered by Mastodon to enhance the user experience of Blasting News readers. The trial EUNOMIA environment is built on the so-called Vertical Channels which are online communities of engaged users around specific topics. Currently, Blasting News readers can discuss EUNOMIA articles featuring in Covid-19 pandemic and Tokyo 2020 Olympics channels.

Blasting News channels on EUNOMIA instance

Vertical Channels are supported by a unique technology developed at Blasting News that thematically aggregates editorially curated news. In this way, readers can stay informed around the topics of their interest without endless scrolling. Thanks to EUNOMIA, Blasting News dedicated channels now feature a button that links directly to a discussion environment, powered by Mastodon.

Blasting News readers can comment, share and endorse posts as they would do on any social media network. Yet, EUNOMIA environment provides its users the opportunity to rate the reliability of the information provided in an article actively participating on the content assessment. In this context, EUNOMIA readers prioritise trusts over likes having a say on what is communicated on online environments. Furthermore, EUNOMIA supports this trustworthiness assessment with dedicated tools such as the history of a post in the EUNOMIA environment, how certain characteristics have changed over time, the account age and the connections indicating potential trolls.

Furthermore, you can have the EUNOMIA app on your phone so you don’t miss the ongoing discussions. EUNOMIA DC is available on google play and App store.

Apart from the technical value of the trial for the development of the EUNOMIA solution, there are three main kinds of value that this approach is likely to generate: business value for Blasting News as an online publisher, business value for the publishing industry, societal value for the user community.

Let’s examine them in turn.

Business value for Blasting News as an online publisher

Blasting News places its utmost focus on the trustworthiness of its content. It has already been deemed a reliable and trustworthy source by NewsGuard, the international organization established to restore trust and accountability in the news industry. Now, it further expands on its success story of its original and innovative civic journalism concept, which promotes freedom of thought and self-expression of non-professional authors, by introducing a ground-breaking comments facility for its thematic groups’ discussion sections.

EUNOMIA environment provides a comments section to Blasting News readers that allows:

  • Rich and dynamic interaction with other readers in a familiar social media style that breaks away from the typical static comments section
  • Extended functionality supporting users themselves to evaluate the trustworthiness of posts, third-party content and comments

Business value for the publishing industry

Many digital publishers, such as online newspapers and magazines, are in a tenuous relationship with the leading social media providers that nowadays serve as primary marketing tools. In exchange for getting access to audiences, these organizations allow social media to use their content to attract more users and advertisers. However, traditional media companies cannot control who, at what rate, and in what way will display ads alongside their content. They cannot impose rules and stopping mechanisms to advertising that might affect the credibility of their content.

EUNOMIA “nudges” readers to become lifetime and engaged members of a permanent, decentralized and privacy respectful supporting community.

The combined use of EUNOMIA with Mastodon offers digital publishers a true ownership of their social media experience. They can decide how their social media platform is used and how the aggregated use of its content can be monetized. Furthermore, the code is open source and free, guaranteeing control over the platform infrastructure.

Societal value creation

EUNOMIA enhances the potential of co-regulating the quality of digital content encouraging its users to assess themselves content trustworthiness. EUNOMIA supports users in this process providing dedicated tools enabling them for example to look into the provenance of online content, recognise the tone of language among other characteristics.

Overall, this is an excellent example of micro co-regulation, as is the use of blockchain technology in establishing the integrity of the data sharing. Unlike the current regulatory scenario applied to centralised social media such as Twitter or Facebook – who have to choose between absolute inclusivity or taking on the role of publishers and editors – future EUNOMIA-powered social media players can remain neutral platforms allowing their users to take ownership of their content and its trustworthiness.

Workshop on Opinions, Intentions, Freedom of Expression,…, And Other Human Aspects Of Misinformation Online at CHI 2021

June 22nd, 2021 by

EUNOMIA joining forces with the EU funded project Co-inform organised an online workshop exploring the human factors of online misinformation. The workshop was hosted at CHI 2021, one of the most prestigious conferences in computer science, which happened online in early May.

The workshop called  “Opinions, Intentions, Freedom of Expression,…, And Other Human Aspects Of Misinformation Online” emerged from a previous collaboration with Co-Inform. The workshop was a success, attracting researchers from across disciplines and geographical locations (i.e. Canada, the US, Belgium, Germany, Brazil, Austria, Italy, and the UK). Furthermore, at the workshop, a representative of WHO was present. This was another success factor for the workshop given that WHO is a key organisation in the fight against the current infodemic.

The workshop followed an engaging and interactive format splitting the presentations of the 9 accepted research statements and the discussions into 3 clusters; 1. Community and Values; 2. Policies and Regulations; and 3. Tools and Technical Solutions.

Misinformation was analysed from a multi-layer perspective exploring and discussing different aspects of this phenomenon, including our beliefs and the role of emotions in human reasoning of online content, as well as the role of trust. Furthermore, technical characteristics of fact-checking such as accessibility and data harmonisation were discussed. Finally, accountability on social media and regulations of social media platforms were also brought into the debate. 

“In an engaging atmosphere, the discussions led to new insights for creating more ethical and impacting technical solutions, which will soon be published by the organisers and participants” as eloquently concluded Dr Lara Schibelsky Godoy Piccolo, Researcher at The Open University and co-organiser of the workshop.

EUNOMIA’s blockchain engine acts as a trust machine

April 14th, 2021 by

Data integrity is a term that refers to the reliability and assurance (validity) of data. One of the main challenges of social media is how to create assurances of data validity, at the same time safeguarding that the data have not been tampered.

In EUNOMIA, all posts are annotated with a “magic” icon (see the image below). When this special icon appears on a post, it means that its blockchain technology guarantees that the integrity of the data e.g., number of trusts, the number of followers and other information related to the post have not been tampered by any administrator or cyber attacker. However, it does not validate whether the post is trustworthy or not. This is for you to decide!

But why is data integrity so important? In cyberspace, online data are likely to be exposed to data manipulations by malicious actors that could use this to their advantage. Especially in social media such actors are distributing compromised pieces of data to their advantage, either to make others act on such data by spreading misinformation (e.g., propagate rumors) or by leveraging on the credibility of other people to claim authorship on certain pieces of digital work (either in plain text or in some visual form).

From the other hand, the actual content creators of such digital artifacts would like to guarantee data integrity towards their online communities (i.e., consumers) of such data. Lastly, and most importantly, they would like to be ensured that there are safeguards in place preventing such manipulation events from happening by other online users.

But how can one certify and prove that the data being presented are free from any data manipulation? EUNOMIA is using a trust engine which builds on a blockchain backbone to provide integrity assurance of the information stored. In addition, the blockchain layer of EUNOMIA creates audit trails of the information to log all the state changes or revisions made to the data.

But isn’t this the same as logging data in some database? Audit trails stored in the same way as the application data are equally vulnerable to tampering and manipulation attacks. There is no mechanism to make hard assertions about data integrity or validate the integrity of such data. In EUNOMIA, we are using a blockchain backbone to make such assertions that can validate the integrity of arbitrary data, and provide for traceability.

But how is this ensured? Blockchain technology builds on a peer-to-peer network where clients (aka nodes) maintain replicas of a distributed data structure (i.e., the blockchain). This data structure organizes pieces of information in the so-called blocks that are linked together with the use of a cryptographic hash function. In brief, the cryptographic hash function is used to create hashes of the information from each block that are linked with each other; since the hash of a block encapsulates the hash of the previous block as a pointer, thus forming a reversed linked list (aka the chain).

This unique characteristic of this data structure is critical for ensuring data integrity. If an attacker attempts to change any piece of information within a past block then the hash of the block changes, resulting in an unresolved pointer breaking the chain. This unreferenced block will not be accepted by the rest of the network.

In addition to cryptographic hashes that build a unique data structure, a blockchain network employs a safeguard mechanism (so-called consensus) that allows independent nodes to, coordinate, approve, and agree on which data should be appended on the data structure. Since the consensus algorithm operates under a distributed environment this ensures that there is no single point of failure, and no central control of the information that could be compromised.

EUNOMIA’s blockchain backbone leverages on the unique characteristics of: blockchain-based hash validation, and consensus offered by the technology to safeguard data attestations and guarantee the integrity of the data.

Exploring political bias in false information spread on social media

February 24th, 2021 by

Social media has become a key source of online news consumption. However, at the same time, social media users are not passive news consumers. They can further distribute online information to their networks and beyond. It is easy then to understand how information that is not always factual or information that promotes hate and violence can be amplified on social media.

This use of social media has an unimaginable impact on the real world as many recent events have shown. One such example is that of the Capitol deadly attack in January 2021, in which social media had a major role to play. Misinformation regarding the transparency of the election process had been spread through social media generating distrust and anger against the newly elected president. Riots are also said to be organised through groups on social media.

It is evident, that social media and misinformation can be harmful and from a political perspective it can threaten democracy. Through our work in the EUNOMIA project, we adopted an interdisciplinary approach to examine political bias in the engagement with false information.

EUNOMIA, a 3-year EU-funded Innovation project, aims to shift the culture in which we use social media focusing on trust, nudging social media users to prioritise critical engagement with online information before they react to it. To this end, it provides a toolkit that supports social media users to assess information trustworthiness. In developing effective solutions, it is necessary to understand the human and societal factors of misinformation.

Our interdisciplinary approach

Within the project, our interdisciplinary team at Trilateral Research leads the work of understanding the social and political considerations in the verification of social media misinformation, and the findings directly feed into further development of the tools. Our approach involved three key stages:

  • Stage 1 – TRI’s social scientists undertook desk-based research to understand the political challenges associated with verifying social media information. This provided insights on how political affinity can influence engagement with misinformation
  • Stage 2 – 19 interviews were conducted with citizens, traditional media journalists, and social media journalists by social scientists. The interviews highlighted how the language used on social media can indicate political bias. Furthermore, information and sources which are politically biased or radicalised are not perceived to be trustworthy.
  • Stage 3 – Building on the findings from stages 1 and 2, Trilateral’s technical team undertook a social network analysis to gain insights on the role of political bias in the engagement with misinformation on social media.

Stage 3 involved the team examining a network of 579 influential Twitter accounts of UK Members of Parliament and a sample of 49 false information accounts. Using UK politics as a case study, enabled the technical team to contribute to the existing heavily US-focused research.

The analysis was conducted using a step-by-step approach.

Within the UK context, the findings suggest that most of the accounts engaging with false information have a Conservative leaning. This can be explained in two ways:

  • False information can be generated and spread mainly by Conservative-leaning accounts, or
  • There is bias in the way fact-checkers label the false information accounts.

The insights emerging from Trilateral’s interdisciplinary approach can be used in the design and development process of relevant tools for tackling misinformation. It also invites fact-checkers and data scientists to explore potential bias when they label accounts as sources of false information. Furthermore, it contributes to media literacy, raising awareness of social media users regarding trustworthiness assessment and further engagement with online information.

The findings encourage social media users to examine the characteristics of accounts that generate and promote content especially with regard to political bias.

EUNOMIA at the Industry Forum of GlobeCom 2020

December 22nd, 2020 by

In the era of COVID-19 pandemic, social media have become a dominant, direct and highly effective form of news generation and sharing at a global scale. This information is not always trustworthy as exemplified by the wide spread of misinformation that proved dangerous for public health. Prof. Charalampos Patrikakis from the University of West Attica -partner of EUNOMIA project- co-organised an event focusing on “Fighting Misinformation on Social Networks” at the Industry Forum session of the Global Communications Conference 2020. GlobeCom2020 is one of the IEEE Communications Society’s two flagship conferences dedicated to driving innovation in nearly every aspect of communications.

The event included presentations by academics and industry representatives followed by an open discussion. Prof. Patrikakis delivered a presentation on “EUNOMIA project: a decentralized approach to fighting fake news”. His presentation referred to the concept of EUNOMIA on the adaptation of information hygiene routines for protection against the ‘infodemic’ of rapidly spreading misinformation. Moreover, EUNOMIA presentation included a more extensive graphic description of the project’s toolkit with its four interrelated functional components: The information cascade, Human-as-Trust-Sensor interface, Sentiment and subjectivity analysis and the Trustworthiness scoring. Participants were also invited to register on EUNOMIA in order to see how this works in real-time.

The pathway to trustworthiness assessment; Sentiment Analysis identification

December 14th, 2020 by

As the amount of content online grows exponentially, new networks and interactions are also growing tremendously fast. EUNOMIA user’s trustworthiness indicators provide a boost towards a fair and balanced social network interaction.

Sentiment analysis is one of EUNOMIA’s trustworthiness indicators assisting users to assess the trustworthiness of online information. It relies on the automatic identification of the sentiment expressed in a user post (negative, positive, or neutral). A sentiment analysis algorithm employs principles from the scientific fields of machine learning and natural language processing. Current trends in the field include AI techniques that outperform traditional dictionary-based approaches and provide unparalleled performance.

Dictionary-based techniques work as follows:  A list of opinion words such as adjectives (i.e. excellent, love, supports, expensive, terrible, hate, complicated), nouns, verbs and word phrases constitute the prior knowledge for extracting the sentiment polarity of a piece of text. For example, in “I love playing basketball” a dictionary-based method would identify and consider the word “love” to infer the positive polarity of the expression.

Figure 1. Sentiment Analysis of user opinions

Unfortunately, these methods are unable to grasp long-range sentiment dependencies, sentiment fluctuations or opinion modifiers (i.e. not so much expensive, less terrible etc.) that exist in abundance in user-generated text.

Figure 2. Demo of how the core of the sentiment analysis component works in EUNOMIA.

We use two models that process user generated content in parallel. The first model relies on sentiment patterns to extract polarity. For example in “not so much expensive” the model would identify the relation between “not” and “expensive” and would assign positive polarity in  comparison to a dictionary-based method that would only rely on the negative word “expensive”.

The second model is an advanced machine learning model, that relies on a trained neural network and it can identify sentiment fluctuations of longer range. Therefore, the first model (pattern-based) relies on sentiment patterns to extract the sentiment orientation, while the second, relies on a neural network that is trained on labeled data and is capable of distinguishing between positive/neutral/negative text with high accuracy.

The output of both models is processed by an ensemble algorithm that decides on the final sentiment classification and the degree that the models are confident about their predictions.

The results of the sentiment analysis process provide one of EUNOMIA’s indicators. Sentiment and emotion in language is connected quite frequently with subjectivity and on many occasions with decietful information. EUNOMIA raises an alert and then the user, by consulting additional meta-information like EUNOMIA’s other indicators can investigate the content further and decide if it is valid and can be safely consumed or shared further to the community.
