TrustServista’s link analysis algorithm is currently used both for automatically generating the Trending Stories you see on the application’s main page and also determining Patient Zero. It relies on analyzing each article’s text and finding links (URLs) and references to publications (such as “according to Associated Press”, but with no link). This link analysis allows TrustServista to track all references across multiple articles and publications, including social media.
The Enhanced Semantic Linking goes on step further by analyzing the similarity of articles and finding common or very similar content shared across them. It could be excerpts from news agencies, statements and quotes or event entire paragraphs (even slightly modified) that are common to multiple articles, even across different websites. This feature not only enriches the view of a Trending Story and the makes the determination of Patient Zero more accurate, but it accurately find how content is repurposed, with or without mentioning the original content owner.
There are now 3 types of article relationships in TrustServista
