C4 Citation list (design cites library workflows in prose form)
The relevant workflow-library papers I drew on were:
| Paper / workflow | Relevant approach used in the recommended outbreak workflow |
|---|---|
| Human-Steered Topic Modelling — Choo et al. (2013), UTOPIAN: User-Driven Topic Modeling Based on Interactive Nonnegative Matrix Factorization | Iteratively classify and refine microblog topics with analyst input; inspect documents, correct misleading terms, merge/split themes, and retrain. |
| Jigsaw: Supporting Investigative Analysis through Interactive Visualization — Stasko et al. (2008) | Extract and validate entities such as places, hospitals, landmarks, organizations, and dates from posts; keep links to original text for evidential inspection. |
| From Movement Tracks through Events to Places — Andrienko et al. (2011) | Identify significant locations through density-based clustering of repeated spatial/temporal events, then analyze their timing and spatial recurrence. Adapted here to symptom-report hotspots rather than movement events. |
| Spatio-temporal Analysis and Modelling — Andrienko & Andrienko (2013) | Aggregate observations into spatial time series; group areas with similar temporal behavior; model temporal patterns; inspect spatial and temporal residuals to refine explanations. |
| Partition-Based Regression Modelling — Mühlbacher & Piringer (2013) | Build interpretable explanatory models incrementally, inspect feature relationships visually, then use residual patterns to identify missing factors or interactions. |
| Detecting Stable Cross-Impact Patterns in Bivariate Time Series — Andrienko et al. (2026) | Examine lagged relationships between a possible driver and later outcomes. Suggested for assessing whether changes in wind conditions consistently precede changes in downwind symptom-report activity. |
| MobilityGraphs: Visual Analysis of Mass Mobility Dynamics via Spatio-Temporal Graphs and Clustering — von Landesberger et al. (2016) | Suggested as an optional extension if anonymized aggregate mobility flows become available, to assess whether mobility between areas explains the apparent progression of outbreak activity. |
These papers informed the workflow structure; the epidemiological transmission hypotheses and validation requirements were designed specifically for the Vastopolis scenario.
