created People in the sun, a consulting firm in the field of big data and artificial intelligence.
Representative of the college of Small and Micro Enterprises, president of the Cluster's
"knowledge" thematic commission since 2011, is president of the board of directors of Cap
Digital.</p>
      <p>His areas of expertise are Big Data, data &amp; text mining, Artificial Intelligence, linguistic
processing and data analysis.</p>

      <p>Abstract. SocialTruth is an European project designed and developed by an international
consortium of 11 partners, whose slogan is “Embedding veracity for social media and web”.
Creating a system that ranks news and certifies their reliability, targeted to professionals and
ordinary users of social media and the web.</p>
      <p>Expert System has conceived a system providing textual and semantic analysis; more concretely
a meta-verification system on story classification and ranking. The global aim of the approach
we have worked on is, based on a golden corpus, comparing an untargeted document to our base
of “qualified documents”. The hypothesis applied lies in the fact that “true news” have a pattern
that our system will highlight, being able to go from a large group of articles to automatically
select a relevant group to compare to a possible “fake news”.</p>
      <p>The system defined goes through the following milestones: The first milestone is the
categorization, having the untargeted document; we analyze it using the categorization process
and reduce the list to compare it to. The second milestone corresponds to narrowing the search
by using the clustering, which means applying an unsupervised categorization among a whole
corpus. The third milestone is the similarity analysis: how similar this document is it to other
equivalent documents? The fourth milestone corresponds to sentiment analysis, whether there is
a strong sentiment present or not in the text and the writing style. Finally, we end up by extracting
the writeprint of the document, language level, tone and type of vocabulary.</p>
      <p>The outcome of our work is the conception of a semantic analyzer that aims at providing
information that will be the input of the expert meta-verification system. The expert
metaverification system will combine the verification results from the content verification services
created from social, semantic and multimedia content, in order to compute a meta-score that
accurately depicts the credibility of the digital content under consideration.</p>
