Multi-Source Context Fusion(MSCF)
Intelligently combines contextual information from multiple sources with quality weighting and conflict resolution
Core Mechanism
Fuses context from multiple heterogeneous sources (indexes, APIs, databases, agents) into a unified, high-quality evidence set using source-quality scoring, alignment/entity resolution, conflict resolution, and provenance‑aware packing—so generation is grounded in the most relevant, timely, and authoritative information.
Workflow / Steps
- Register sources and capabilities: indexes, APIs, tools, agent endpoints; define schemas and access policies.
- Retrieve/ingest per source with hybrid search or tool calls; capture metadata (recency, authority, permissions).
- Normalize + canonicalize: deduplicate near‑duplicates; unify schemas; perform entity resolution and ID mapping.
- Score candidates: relevance, recency, authority, consistency, and coverage; calibrate per‑source weights.
- Align + reconcile: map entities/claims across sources; detect contradictions and temporal ordering.
- Fuse results: use late/ensemble fusion (e.g., Reciprocal Rank Fusion) or learned aggregators with confidence weights.
- Resolve conflicts: apply policies (temporal precedence, source authority, majority/consensus, abstain/defer).
- Assemble context: compress and pack with citations, timestamps, and source attributions within token budgets.
- Generate + verify: produce answer; check faithfulness/groundedness; iterate if confidence or coverage is low.
- Log + evaluate: record per‑source contribution, costs, latency; run ablations to quantify fusion gains.
Best Practices
When NOT to Use
- A single authoritative, fresh source already satisfies quality and SLOs.
- Hard real‑time paths with tight p95 latency where fusion overhead breaks budgets.
- Strict compliance regimes that prohibit cross‑source mixing or external augmentation.
- Sparse or highly conflicting sources without a viable resolution policy or human review.
- Severe cost constraints where additional sources do not measurably improve outcomes.
Common Pitfalls
- Near‑duplicate inflation causing biased scores and repeated context.
- Over‑weighting popularity/recency signals → drift or stale claims overriding authoritative corrections.
- Ignoring permissions/tenancy; leaking restricted data into fused context or logs.
- No temporal reconciliation: mixing outdated and current facts without validity windows.
- Unbounded context packing leading to truncation and lost citations.
Key Features
KPIs / Success Metrics
- Answer faithfulness/groundedness and citation coverage; contradiction rate.
- Fusion gain vs best single source and vs no‑fusion baseline (quality uplift).
- Redundancy/duplication rate after dedup; entity resolution precision/recall.
- Recency hit rate and freshness adherence; authority agreement rate.
- Latency p50/p95 and cost per answer; tokens packed per answer.
Token / Resource Usage
- Late/ensemble fusion to limit packing; prefer RRF/weighted votes over concatenating large contexts.
- Per‑source top_k and dynamic budgets; compress extractively with citations; sample by marginal gain.
- Cache per‑source retrieval/reranks; reuse across hops and related queries.
- Use lightweight models for scoring/evaluation; reserve strongest model for final synthesis.
- Stream results and early‑exit when confidence and coverage meet thresholds.
Best Use Cases
- Enterprise 360° customer view: CRM + support + analytics + communications.
- Compliance, finance, or risk where multiple authoritative sources must agree.
- Research synthesis combining papers, structured databases, and web sources with citations.
- Multi‑agent systems aggregating specialist outputs into a coherent, validated summary.
- Incident response and observability: logs + metrics + traces + tickets for rapid triage.
