Abstract: Data investigations are performed by querying a plurality of data sources. A system receives an investigation input and queries a plurality of data sources in accordance with the received input. The system receives, in response to the querying, response data from the plurality of data sources, and generates and stores a data structure representing relationships between the first investigation input and the first response data. The data structure may be in the form of a knowledge graph. The system may generate and display a visualization of the data structure. The system may generate and store a record of investigation steps used to generate the data structure, such that the investigation steps may be applied in future instances, for example using different inputs, to generate new data structures.

Abstract: A method for reducing a patron's waiting time at a walk-in facility includes providing a communications network, wherein the communications network includes a first communications link between a patron and a walk-in facility. The method includes providing a queue, receiving a consultation request via the first communications link, reserving a position in the queue in response to the consultation request, determining a time period before a consultation is available, and providing notice to the patron of the determined time period, wherein the patron may wait at a location other than the walk-in facility during the determined time period, thereby reducing the patron's need to wait at the walk-in facility before being consulted at the walk-in facility.
