Computing controversy News

Controversy news are the outcome of a multi-step process including:

Content Collection

RavenPack analyzes textual content from high-quality sources to identify events that match any of the targeted categories. Documents considered include English and non-English news in 13 languages, and social sources.

Information Extraction

Additional filters ensure the data remains focused on contemporary observations. The exact process is fully documented.

Signal Construction

Controversy factors are then produced for each detected company, 7 times per day, at midnight UTC and at the open & close in New York, Paris, and Tokyo. The score itself is on a positive, open-ended scale that quantifies the magnitude of a controversy along with its relevance in the media. It is influenced by the volume of news behind a controversy, the number of languages where it is picked up, the same for number of sources, its novelty, and whether the controversy is able to carry a headline. The signal also applies a decay to aging controversy reports.

Factor Composition

Controversy Factors are gathered in daily files that detail all the companies for which controversies have been detected on a given universe.
