Semantic search alone is not enough to capture all connected facts, they will capture the semantically most identical memory only.
Tested on HotpotQA public dataset:
Vector + BM25 + entity graph: BothFound@5 71.5% Vector + BM25 only: BothFound@5 59.5%
Entity graph is the game changer to extract connected facts.
More Benchmark result:
LongMemEval-S: 84.8% recallAll@5 LoCoMo-10: 59% vs zep cloud 28%
