Elsevier Smart Content LDR SemTech 2012

Published on

A session from SemTech SF in June 2012

Abstract: As access to a richer set of knowledge and research continues to be critical to the healthcare community, the users of healthcare and life science solutions are demanding the same level of discoverability, integration, and innovation from their professional tools that they enjoy in their personal applications. Through the Smart Content initiative Elsevier seeks to semantically enrich its diverse offerings of health sciences content to both improve the performance of existing online resources as well as to enable the creation of the next generation of digital products. In this session, Alan Yagoda will discuss Elsevier’s efforts in developing Smart Content capabilities to power a new portfolio of strategic product offerings. The journey into smarter search and discovery resulted in a new infrastructure with a rich set of semantic capabilities include the development of a standardized medical taxonomy called EMMeT (Elsevier’s Merged Medical Taxonomy), indexing and content enrichment, and linked data services.
