A method of generating a sequence of commands to gather information using a directed tree graph includes providing a plurality of goals, each goal having a weighting, and a set of commands that lead to completion of the goals. A directed tree graph is constructed comprising a root node, respective leaf nodes associated with the goals, and one or more parent nodes. Each node is associated with one command, the command having the potential to complete any goals associated with the node and all the goals associated with any subordinate nodes. The priority of each command is determined, based on the sum of the goal weightings of leaf nodes subordinate to the node associated with the command. One or more commands is executed, a command having a higher priority being executed before a command having a lower priority.

A mechanism is provided in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions which are executed by the at least one processor and configure the processor to implement a conversation scope system, comprising a conversation scope controller and a conversation scope extractor, for progressively extending conversation scope in a multi-user messaging platform. The conversation scope controller captures an utterance input by a user into a chat platform. The conversation scope extractor determines a conversation scope for the utterance based on at least one entity extracted from the entity. The conversation scope controller directs the utterance to a messaging chat room based on the determined conversation scope.

An approach is described for authenticating a user. An associated method includes displaying a dynamic image on a display screen, detecting a user interaction with the displayed image, and detecting a duration of the detected user interaction. The method further includes comparing the detected user interaction and the detected duration with a stored user interaction and a stored duration. The method further includes authenticating the user upon determining that the detected user interaction matches the stored user interaction and the detected duration matches the stored duration. In an embodiment, the method further includes transmitting the detected user interaction and the detected duration to a remote device. In such embodiment, the method step of comparing the detected user interaction and the detected duration with the stored user interaction and the stored duration is performed by the remote device.

User authentication using temporal knowledge of dynamic images

Message validation in a service-oriented architecture defines a message structure using XML data types. Context-independent validity constraints are specified using an XML schema. Context-specific validity constrains are specified in an intermediary data structure for a specific service operation. A service interface including the XML schema and the intermediary data structure is published.
