Abstract: Embodiments of the present disclosure resolve natural language temporal expressions into temporal values via a temporal expressions processor that parses a given temporal expression into one or more semantic parses, selects an optimal semantic parse and resolves a value for the optimal semantic parse. The temporal values may pertain to one or more calendar dates, one or more calendar periods, one or more clock times, a clock time period and/or a combination of the above.

Abstract: Advanced systems and methods for temporal planning employ a temporal logic for representing and reasoning about temporal constraints over both logic and numeric (discrete and continuous) variables and continuous time. A temporal planning language represents a world model, and adapts the temporal planning language to support formulas expressing the temporal logic. Embodiments of the present disclosure also can receive a temporal planning problem and derive one or more solutions to the temporal planning problem using one or more of the formulas. Embodiments of the present disclosure further address re-planning such as, for example, when a new objective task is added to the set of objective tasks to be performed, when an existing objective task is cancelled, and/or when some event occurs unpredictably and invalidates the current plan.

Abstract: A method and system for reducing the number of cases in a cased based reasoning system that are considered applicable to a current problem for a specific complex apparatus. In addition to a database of previously solved cases, the system has a domain database containing all components that make up a set of apparatus. The system also has a database containing configuration knowledge which defines the components from the domain that are excluded from a specific apparatus. The configuration information is used to filter any cases from consideration as potential solutions if they reference components not in the configuration of the specific apparatus for which the current problem exists. The configuration knowledge is also used to display to the user only the components that make up the specific apparatus for which the current problem exists. The configuration knowledge also includes information on default values for components within the specific apparatus.

Abstract: A method and system for assisting a user in solving a new problem case within a selected domain, such as a complex apparatus.
