Abstract: A technique for running queries is provided that includes a method and system for managing unstructured data and for capturing uncertain relationships between pieces of data. A structural schema is generated from unstructured data that is configured to evolve in response to user input and incoming data that is changing over the course of an application. The schema is also configured to capture relationships between data that are uncertain or difficult for a person to capture in a consistent or comprehensive manner. The technique is especially advantageous for running and returning meaningful responses to queries that require an ability to connect pieces of data received from unstructured data or disparate sources, including user input, or where the query is directed to information that is uncertain or was not anticipated as useful or relevant at the time the data containing the information was originally received.
