Knowledge Graphs in NLP Definition

Knowledge Graphs in NLP represent interconnected relationships and entities, creating a structured network of knowledge that machines can interpret. These graphs link people, places, concepts, and events, enabling machines to understand and infer context in text data, making them essential for applications like question answering, information retrieval, and sentiment analysis. Key technologies in creating knowledge graphs include ontology-based models, RDF (Resource Description Framework), and SPARQL querying.

Knowledge Graphs in NLP Explained Easy

Imagine a big web where everything in the world is connected with strings—like a map that connects words, ideas, and objects. For example, if you connect "dog" to "animal" and then to "bark," you create links showing how these ideas relate. In NLP, knowledge graphs help computers understand these connections to make sense of words and meanings.

Knowledge Graphs in NLP Origin

Knowledge graphs have origins in early AI research focused on representing structured knowledge. Over the last few decades, as AI and computational linguistics advanced, knowledge graphs have become more sophisticated, especially with Google introducing a Knowledge Graph in 2012 to enhance search results with contextual information.

Knowledge Graphs in NLP Etymology

The term "knowledge graph" refers to a graph-based structure that encodes knowledge, where nodes represent entities and edges represent their relationships.

Knowledge Graphs in NLP Usage Trends

Recently, knowledge graphs have gained popularity in sectors requiring advanced NLP capabilities, like e-commerce, digital assistants, and content recommendation systems. They’re crucial for enhancing user experiences by providing precise, context-aware responses. The shift towards explainable AI has also boosted interest in knowledge graphs, as they offer a transparent representation of data connections.
