Source Credibility [DEPRECATED]

Please note that this service has been deprecated and may be removed without warning. It has been replaced by the Domain Credibility service.

An application that annotates URLs within a document and assigns to each a score that details how credible a source the URL points at. Clearly this makes the most sense for URLs pointing twoards known sources of news.

Default annotations
:DomainCredibility Annotations spanning URLs for which we have credibility information about the responsible domain. A URL may have more than one of these annotations spanning it if we have credibility information from multiple sources. These have additional optional features:
  • credibility-source, the source from which the credibility information was collected.
  • credibility-timestamp, the date on which the credibility information was collected or last updated.
  • credibility-score, a score between 0 and 1 that signifies how credible the source is. A higher score suggests the source is more credible.
  • credibility-color, green for credible, red for less so, with grey in the middle of the range.
  • credibility-resolved-url, the full URL that the URL in the document resolved to. This is important in the case of URL shorteners etc.
  • credibility-domain, the credibility info is domain based (rather than URL based) and this feature shows the domain used to lookup the details in each of the sources we use.
  • credibility-category, if a label was provided by the original source this will be based through in it's original form. The exact set of labels changes over time (as we pull in new sources) but currently includes: left, left center, center, right center, right, pro science, Conspiracy, fake news, clickbait, Conservative, fake, Liberal, Satire, and unreliable. Note that because there is no normalization of these labels there is repetition and overlap.
:URL The features from the DomainCredibility annotation with the lowest credibility-score are attached to a single URL annotation.
