Multidimensional Knowledge Graphs: Future of RAG
Read Full Article: Multidimensional Knowledge Graphs: Future of RAG
In 2026, the widespread use of basic vector-based Retrieval-Augmented Generation (RAG) is encountering limitations such as context overload, hallucinations, and shallow reasoning. The advancement towards Multidimensional Knowledge Graphs (KGs) offers a solution by structuring knowledge with rich relationships, hierarchies, and context, enabling deeper reasoning and more precise retrieval. These KGs provide significant production advantages, including improved explainability and reduced hallucinations, while effectively handling complex queries. Mastering the integration of KG-RAG hybrids is becoming a highly sought-after skill for AI professionals, as it enhances retrieval systems and graph databases, making it essential for career advancement in the AI field. This matters because it highlights the evolution of AI technology and the skills needed to stay competitive in the industry.

GraphQLite: Embedded Graph Database with SQLite
Read Full Article: GraphQLite: Embedded Graph Database with SQLite
GraphQLite is an SQLite extension designed for those building GraphRAG systems who prefer not to use Neo4j for storing knowledge graphs. It introduces Cypher query support, allowing users to store entities and relationships in a graph structure and utilize Cypher for context expansion during data retrieval. By integrating with sqlite-vec for vector search, GraphQLite provides a comprehensive embedded RAG stack within a single database file. It also includes graph algorithms like PageRank and community detection, which help identify key entities and cluster related concepts. This extension is particularly useful for developers looking for a streamlined solution to manage graph data efficiently. This matters because it offers a lightweight, integrated alternative for handling complex graph data without the overhead of additional database systems.
