Retrieval Event

• CURIE: gmeow:RetrievalEvent
• IRI: https://blackcatinformatics.ca/gmeow/RetrievalEvent
• Category: class
• Defined by: gmeow:slices/graphrag
• Box roles: TBox role (What is this?)

One retrieval against a vector index: the query, the index queried, and the chunks returned — the answer to 'why did the model see this passage?'. An agent-memory recall is a RetrievalEvent too (the core MemoryItem doctrine's read operation). Per-chunk relevance rides gmeow:retrievalScore statement annotations on each gmeow:retrievedChunk triple.

Structure

Subclass of: gmeow:Activity

Practical Pattern
