This slide is a section header titled "What is a Knowledge Graph?" It defines a knowledge graph as a knowledge base using graph-structured data to represent entities, events, and relationships with semantics.

The slide titled "Key Definitions" describes a knowledge graph as a system that stores interlinked entity descriptions, encodes relationships and semantics, and enables knowledge representation and reasoning. Examples provided include Google's KG and Wikidata.
The timeline outlines the history of knowledge graphs, starting with 1970s entity-relationship models and the 2010s rise of Semantic Web technologies like RDF and OWL. It highlights Google's 2012 Knowledge Graph launch for better search, followed by 2020s enterprise and AI adoption.
1970s: Entity-Relationship Models Emerge Foundational concepts for modeling data entities and relationships introduced. 2010s: Semantic Web Technologies Rise RDF, OWL, and linked data standards fuel structured web knowledge. 2012: Google Launches Knowledge Graph Google introduces KG to improve search via entity understanding and connections. 2020s: Enterprise and AI Adoption Knowledge graphs integrated into enterprise systems and AI applications widely.
The slide "Popular Implementations" highlights key knowledge graphs and graph databases. It lists Google Knowledge Graph as the largest public KG, DBpedia (RDF from Wikipedia), Wikidata (multilingual structured data), Neo4j (enterprise graph database), and Stardog (enterprise KG platform).
In knowledge graphs, entities are discrete nodes representing objects, events, or concepts like people, places, dates, or ideas, forming structured data building blocks. Relationships link these entities using flexible, natural language predicates to capture nuanced connections beyond rigid schemas, enabling rich interactions.

The slide "Visualizing a Knowledge Graph" depicts a graph where nodes represent entities or concepts, and edges illustrate relationships between them. This structure highlights interconnections and enables semantic queries and inference.

This slide serves as a section header titled "Advanced Applications." Its subtitle highlights "Reasoning over data and entity alignment in knowledge graphs."
Reasoning over data and entity alignment in knowledge graphs
Using Knowledge Graphs (KG) for reasoning enables querying highly interconnected data and performing inference through semantic relationships. It also supports seamless integration with AI/ML models and real-time retrieval from dynamic knowledge sources.
Entity Alignment aligns identical entities across multiple graphs to enable seamless data integration. It leverages embeddings and machine learning for similarity detection, boosting knowledge graph accuracy and completeness.
