Populating and Leveraging Semantic Knowledge Graphs to Supercharge Search

Explore how to enhance search capabilities by creating and utilizing semantic knowledge graphs in this conference talk from Haystack US 2023. Learn techniques for detecting, acquiring, and organizing knowledge from text using automated Natural Language Processing (NLP) methods, enabling searches for concepts rather than just keywords. Discover how to recognize conceptual entities and relationships from English documents and insert them into a semantic knowledge graph. Uncover new possibilities for both offline and online applications, including building synonym lists, enriching documents, query expansion and relaxation, tuning boosts, choosing optimal query handlers, and performing user intent recognition. Understand the benefits of loading additional text to expand the system's knowledge base and improve long-tail query matching. Gain insights into how subject matter experts can explore and refine the graph, making additions and corrections to further enhance search performance.
