Echo Engine
Sentiment Propagation
Maps how consumer sentiment propagates across competing brands and geographies. Surfaces monitored review movement context through sentiment network propagation, historical relationship scoring, and analyst-ready evidence review.
Sentiment Does Not Exist in Isolation
When a major brand experiences a meaningful shift in consumer perception, that change does not stay contained. It propagates -- across geographies, across competitor sets, and across consumer segments. Echo Engine is built to model and quantify these cross-brand sentiment cascades.
Using spatial sentiment propagation modeling, Echo Engine maps how a shift in one market is likely to affect adjacent brands and geographies. The dashboard signal is delivered through a fast database-backed proxy for production latency, while deeper simulation work stays on dedicated analysis endpoints.
This is a structured propagation model for how sentiment moves through interconnected brand ecosystems. The goal is to surface earlier context for analyst review, not to pretend the landing page is a fully autonomous decision engine.
Multi-Dimensional Signal Generation
Six practical capabilities that turn review data into monitored propagation context for the desk.
Geographic Propagation Mapping
Models how sentiment shifts in one market propagate to adjacent geographies. A decline in the Northeast may forecast similar movements in the Mid-Atlantic within 2-4 weeks.
Cross-Brand Contagion Analysis
Quantifies how sentiment changes at one brand affect direct competitors and adjacent categories. Captures both negative spillover and positive substitution effects.
Confidence-Weighted Review Labels
Every review movement label includes evidence context based on simulation convergence, historical accuracy, and observed signal strength. No unsubstantiated calls.
Scenario-Weighted Propagation Scoring
Each analysis cycle scores propagation scenarios using historical relationship weights, decay assumptions, and competitor context so the desk can compare likely spillover paths without overstating certainty.
55,000+ Location Network
The propagation model spans our full location universe. Every monitored location serves as both a data input and a potential propagation node in the sentiment network.
Workspace-Level Intelligence
Signals are designed for operational review workflows. Outputs include category-level aggregation, relative review movement, and risk context for monitored chains.
From Shift to Signal
A four-stage pipeline that turns observed sentiment shifts into monitored propagation signals and analyst-ready context.
Shift Detection
When Neural Core identifies a statistically significant sentiment change, Echo Engine ingests the full context: magnitude, velocity, geographic scope, and brand positioning.
Network Modeling
The propagation model maps the detected shift against the brand relationship graph, identifying which competitors, geographies, and consumer segments are most likely to be affected.
Multi-Path Simulation
Propagation scenarios are scored with relationship weights, decay assumptions, and competitive dynamics to generate a probability-weighted view for analyst review.
Review Signal Generation
Simulation results are aggregated into operational review labels with confidence context. Each label includes supporting evidence, expected time horizon, and comparable historical precedents.
