Start with lawful, rate‑limited connectors, rotating identities respectfully, and caching to avoid redundant pulls. Normalize text encodings, strip boilerplate, and mark provenance so sources remain traceable. Careful batching keeps costs predictable, while backpressure prevents downstream overload. The ingestion layer becomes a steady heartbeat, ensuring review volume rises without drowning the summarizer or flooding dashboards with duplicated, noisy fragments.
Cleaning data should not erase meaning. Instead of crushing everything into star scores, maintain sentence‑level references, product variants, and version tags. Keep regional context and language cues, because a charger complaint in one country may be irrelevant elsewhere. With careful schemas, the summarizer can respect context, compare apples to apples, and tell you when a mismatch would distort conclusions.
Mix open and hosted models: fast smaller models for clustering, stronger ones for nuanced summarization. Cache aggressively, batch prompts, and tokenize smartly to reduce spend. Guardrails prevent off‑topic generations, and a fall‑back policy handles timeouts gracefully. The result is a responsive system that keeps quality high while ensuring total cost of ownership remains predictable as volume grows.
Measure more than fluency. Track factual consistency via citation checks, aspect coverage, contradiction handling, and user‑rated usefulness. Build a golden set of annotated reviews for regression tests, and simulate adversarial inputs like coordinated review spikes. With continuous evaluation, you know when a model upgrade actually helps, and avoid quiet quality regressions that only surface as user churn later.
Invite editors and domain experts to correct summaries, mark missing aspects, and approve category glossaries. Feed their actions back into training through preference data and constraint updates. Prioritize interventions where confidence is low or impact is high. This selective curation keeps throughput fast, improves quality where it matters, and builds organizational ownership rather than a mysterious black‑box dependency.
