GICS Documents — Introduction

Some documents collected by Bilby are relevant to to one or more nodes in the GICS taxonomy tree, used by analysts to classify equities down to one of four levels of granularity: sectors, industry groups, industries and sub-industries. Bilby enriches the data rows corresponding to such documents with fields describing these GICS nodes and their degree of relevance to the document. These enriched rows form the gics dataset. Note that if a document is relevant to three gics nodes, then it generates three rows in the gics dataset. For this reason, the number of rows in a daily gics table returned by the Bilby API can exceed the number of documents Bilby collects on this day.
