To identify trends and assign metadata elements such as location and sentiment to the correct entities, Web intelligence applications require methods for linking named entities and revealing relations between organizations, persons and products. For this purpose we introduce Recognyze, a named entity linking component that uses background knowledge obtained from linked data repositories. This paper outlines the underlying methods, provides insights into the migration of proprietary knowledge sources to linked enterprise data, and discusses the lessons learned from adapting linked data for named entity linking. A large dataset obtained from Orell Füssli, the largest Swiss business information provider, serves as the main showcase. This dataset includes more than nine million triples on companies, their contact information, management, products and brands. We identify major challenges towards applying this data for named entity linking and conduct a comprehensive evaluation based on several news corpora to illustrate how Recognyze helps address them, and how it improves the performance of named entity linking components drawing upon linked data rather than machine learning techniques.
