Abstract: A method for event detection includes: obtaining a subpopulation data from a graph structure for performing a graph analysis, wherein the subpopulation data is associated with personality and demographic characteristics of users; obtaining a user profile associated with a target user; inferring psychological traits of the user by performing the graph analysis based on the user profile and the subpopulation data; performing an outcome linkage analysis based on labeled event outcome profiles and the inferred psychological traits to generate personalized knowledge graph data associated with the target user; and profiling, monitoring, or performing an anomaly detection for event data streams based on the personalized knowledge graph data.

Abstract: A system and a method for providing a digital intervention relating to user interactions. A system may have at least one processor configured to perform operations comprising: receiving input data from at least one client device; accessing a data model configured to determine, based on historical data, risk levels associated with the user interactions; inserting the input data into the data model; receiving, from the data model, an indication that at least one determined risk level associated with the user interactions exceeds a preset threshold; and providing, in response to the at least one determined risk level exceeding the preset threshold, the digital intervention.
