Article Types and Categories

Article Types and Categories

Trustium analyzes each article using more than 20 key indicators and summarizes the assessment with categories: Credibility, Sentiment and Bias. Red, orange and green icons encourage readers to apply critical thinking and skepticism when appropriate and signal misinformation before they share it.


Trustium can identify many types of articles such as News, Opinion and Satire.


Trustium is designed to assess articles that appear to cover news events accurately and objectively. This type of article conveys the who, what, where, when, why, and how concerning people and events, without giving opinions or biased information.


An opinion article is an article about news events that is not based on neutral facts surrounding the events, but rather expresses a person or organization’s opinions or beliefs about events. Commonly found in pieces labeled as opinion, op-eds, blogs, or editorials.


Satire includes articles often based on true people and events, but with a humorous twist or mocking tone. Satire differs from comedy, in that satirical articles will often present a story related to true events and in the format of a news article, but mocking something. These are often not trying to harm or spread false information, but some satire can trick people into believing it is true. This is often seen on sites such as The Onion and The Borowitz Report.

Categorization of Articles

The following definitions of these categories are provided to help consumers to better understand Trustium’s assessment. In addition, those who provide feedback to correct a story assessment should use these definitions to guide their ratings.



Credibility is assessed on a continuum between credible and questionable. A credible article demonstrates high journalistic standards, does not show bias, and conveys truthful information. A questionable article may lack references to sources, data, expert quotes, or has not been fact-checked. This type of article may convey false information and it may be a clickbait article. It most likely does not adhere to the standards of journalistic writing.


Bias is assessed on a continuum between Impartial and Biased. Impartial articles present facts supported by evidence and quotes from outside, credible sources. It avoids partisan language and makes an effort to account for both sides of an issue, a balance of positive and negative. Biased articles often favor or oppose a subject. They may contain relevant facts, but are primarily focused on convincing the reader to believe in a particular way.


Sentiment is assessed on a continuum between Objective and Emotional. Articles that are Objective may use measured terms to describe events and avoid the use of dramatic or sensational language. Articles that are Emotional may include language that is provocative, sensational or even vulgar. Some hallmarks of emotional articles include the use of all caps or the use of positive or negative adjectives to evoke strong feelings in the reader.
