JEL: Applying End-to-End Neural Entity Linking in JPMorgan Chase

TL;DR

This paper introduces JEL, an end-to-end neural entity linking model tailored for enterprise knowledge graphs, demonstrating state-of-the-art performance in linking financial news mentions to company entities.

Contribution

The paper presents a novel neural entity linking approach that effectively handles enterprise-specific data, outperforming existing methods tuned for Wikipedia entities.

Findings

JEL achieves state-of-the-art accuracy in linking financial news to company entities.

The model is deployable at enterprise scale for real-time alerts.

Methodology is adaptable to other enterprise-specific entity linking tasks.

Abstract

Knowledge Graphs have emerged as a compelling abstraction for capturing key relationship among the entities of interest to enterprises and for integrating data from heterogeneous sources. JPMorgan Chase (JPMC) is leading this trend by leveraging knowledge graphs across the organization for multiple mission critical applications such as risk assessment, fraud detection, investment advice, etc. A core problem in leveraging a knowledge graph is to link mentions (e.g., company names) that are encountered in textual sources to entities in the knowledge graph. Although several techniques exist for entity linking, they are tuned for entities that exist in Wikipedia, and fail to generalize for the entities that are of interest to an enterprise. In this paper, we propose a novel end-to-end neural entity linking model (JEL) that uses minimal context information and a margin loss to generate entity embeddings, and a Wide & Deep Learning model to match character and semantic information respectively. We show that JEL achieves the state-of-the-art performance to link mentions of company names in financial news with entities in our knowledge graph. We report on our efforts to deploy this model in the company-wide system to generate alerts in response to financial news. The methodology used for JEL is directly applicable and usable by other enterprises who need entity linking solutions for data that are unique to their respective situations.
