Contextual information extractor with model explainability calculator

Embodiments of the invention are directed to accurate resource interaction opportunity decisioning. Contextual information is extracted, in real-time or otherwise, which takes into account the circumstances surrounding the presentation of resource interaction opportunities to the potential user. A decisioning model from amongst a plurality of models is determined based on implementation of an explainability calculator that assesses the accuracy, peril and complexity of the models in relation to the resource interaction opportunity decisions rendered by the models. A relationship builder is implemented that is configured to build a relationship network amongst potential users and resource interaction opportunity providers and subsequently use the indirect relationships provided by the network as a basis for determining which resource interaction opportunity providers should provide resource interaction opportunities to the potential users.
