What Does a Information Scientist (AI) Do?
Information Scientists design systems for organizing and accessing knowledge. They develop ontologies that formally represent domain knowledge, build knowledge graphs connecting entities and relationships, design information architectures that help users find and understand information, develop semantic search and retrieval systems, and apply AI to improve information discovery and inference.
A Typical Day
Ontology design: Design ontology representing medical knowledge for health company
Knowledge graph: Build and maintain knowledge graph of diseases, treatments, symptoms
Information architecture: Design taxonomy for enterprise knowledge management system
Semantic search: Implement semantic search system understanding user intent
Reasoning: Develop inference rules enabling automatic knowledge discovery
Integration: Integrate knowledge graph with downstream applications
Quality: Ensure knowledge graph quality and consistency
Key Skills
Career Progression
Information scientists typically lead knowledge management and information architecture programs. May become Director of Knowledge Management or Chief Information Officer.
