Multi-modal knowledge retrieval system with graph-constrained semantic search

A computing system is disclosed for augmenting semantic retrieval using structured knowledge constraints. The system obtains content segments from one or more source documents and processes the content through a dual-indexing pipeline that generates vector embeddings and constructs a graph representation of inter-segment relationships. A vector index and a graph-based structure are maintained in parallel to support retrieval workflows. Upon receiving a search query, the system initiates vector-based retrieval to identify semantically similar segments and concurrently traverses the graph to identify contextually connected segments. Retrieved segments are cross-referenced using constraint resolution logic that evaluates identifier overlap, relationship proximity, and graph alignment metrics. The system adjusts relevance scores using adaptive weighting and structural validation and produces a unified ranking of content segments. Validated results may be presented for review, integrated into external applications, or refined through feedback signals that update scoring parameters and edge weights over time.
