Huge amounts of unstructured textual data are the foundation of ARTIS®. Data sources, such as financial news, annual reports, or business descriptions, ensure a broad picture.
Hundreds of thousands of documents are individually evaluated, and each document’s relevance to the respective theme is calculated by a state-of-the-art NLP ranking function.
Among all relevant documents, companies are tagged, extracted, and mapped against Solactive’s proprietary symbology data base.
Each company’s theme relevance is calculated. These theme relevancies, i.e., “ARTIS® scores”, are used to rank companies according to their thematic fit. The resulting universe of companies is the basis for the index construction.
