# Source Trust Tuple **Domain:** Austin Research / Concepts **Doc Type:** Corpus analysis **Source basis:** Supplied research cluster with linked references; see the [[wiki/Austin Research Evidence Map|evidence map]] for verification scope. The **Source Trust Tuple** is the six-part representation described in UT’s announcement of the [[wiki/Surety BioEvent App|Surety BioEvent App]]: **Identity, Expertise, Reputation, Experience, Authority, and Separation**. It characterizes a data source so an optimization process can evaluate its suitability for particular surveillance goals. The key operation is contextual weighting. A source that helps seasonal influenza estimation may mislead during a pandemic; collecting more of it can worsen the estimate. BioEvent therefore treats source choice as part of inference itself. The tuple concerns the reliability of observations and their providers. VVUQ concerns the calculation and adequacy of a model. Both matter to consequential prediction, but neither can substitute for the other. The public announcement names the dimensions without supplying a complete operational scoring specification. ## Connected entries [[wiki/Surety BioEvent App|Surety BioEvent App]] · [[wiki/Suzanne Barber|Suzanne Barber]] · [[wiki/Biosurveillance Ecosystem|Biosurveillance Ecosystem]] · [[wiki/Provenance|Provenance]] · [[wiki/Verification Validation and Uncertainty Quantification|Verification Validation and Uncertainty Quantification]] · [[wiki/Information Asymmetry|Information Asymmetry]] · [[wiki/Biometric Presentation Attack Detection|Biometric Presentation Attack Detection]] · [[wiki/Google Flu Trends|Google Flu Trends]] · [[wiki/Multi-Use Inference and Control|Multi-Use Inference and Control]] · [[wiki/Xpress and Xtend|Xpress and Xtend]] ## Sources and corpus context - [[research/The Austin Executable Loop|The Austin Executable Loop — master document]] - [Prof. Suzanne Barber Awarded DTRA Grant for Work on Surety BioEvent App](https://ece.utexas.edu/news/prof-suzanne-barber-awarded-dtra-grant-work-surety-bioevent-app) **Cluster:** [[wiki/Austin Executable Loop|Austin Executable Loop]] · [[wiki/Austin Research Evidence Map|Austin Research Evidence Map]]
