A carefully built, well applied and intuitively surfaced taxonomy can really help us reach the holy grail of search, namely increased recall and precision in results. This work looks at how we construct taxonomies at LexisNexis that match content volume and customer need to provide topics that are granular enough to be actionable, insightful and helpful in decision-making. It covers both rule-based and machine learning classification approaches to content enrichment and demonstrates how we combine these to achieve compelling and differentiating accuracy. It looks at the various ways we have surfaced taxonomy in our products both to enable our customers to get to the comprehensive information they want faster and increasingly to drive powerful analytics. Finally, we look to the future and consider how we can increase usage of our taxonomies both explicitly and ‘hands-free’ in our products to continue to boost relevance, improve findability and better understand query intent.
