To provide AI researchers with modern tools for dealing with the explosive\ngrowth of the research literature in their field, we introduce a new platform,\nAI Research Navigator, that combines classical keyword search with neural\nretrieval to discover and organize relevant literature. The system provides\nsearch at multiple levels of textual granularity, from sentences to\naggregations across documents, both in natural language and through navigation\nin a domain-specific Knowledge Graph. We give an overview of the overall\narchitecture of the system and of the components for document analysis,\nquestion answering, search, analytics, expert search, and recommendations.\n
