Applied Named Entity Recognition @ Bloomberg

Bloomberg deals with a wealth of heterogeneous data, including (but not limited to): reports from financial analysts, earnings releases, company filings, news stories, web scrapes, social media posts, ticker symbols, and pricing information of a wide variety of securities. With 80% of financial data in unstructured formats, the ability to quickly identify named entities automatically is essential to understanding this content.

We will briefly introduce Bloomberg’s products that use this technology and present the unique challenges related to Bloomberg’s data and business. We will then present four of our recent publications that aim to tackle the following challenges: heterogeneity of content, temporal data drift, ensuring high precision in tagging or tagging entities as they are typed.
