Abstract: In some examples, a messaging service facility receives a message from a spoke device requesting a service provided by a target device. The messaging service facility determines, in response to the message received at the input address of the cell, an output address of the cell. The messaging service facility sends the message to the target device using the determined output address to provide access of the service by the spoke device.

Abstract: Embodiments of the present invention provide a service access control system having a service object for providing services, a messaging service facility and one or more spoke entities for accessing services provided by the service object, wherein the messaging service facility comprises one or more cells each having an input address and an output address, wherein at least one of the input address and the output address is linked to the other via a cryptographic key, the cell providing a message communication link between the spoke entity and a set of functions on the service object associated with the cell.

Abstract: Systems and methods for classification of documents based on topic to which the documents pertain are described herein. In one implementation, the method comprises computing a probability of a document being topical based on a number of constituent elements that are topical and a total number of constituent elements and computing a probability of the document being anti-topical based on a number of constituent elements that are anti-topical and the total number of constituent elements. The method further comprises determining whether the probability of the document being topical is greater than the probability of the document being anti-topical. Thereafter, the method includes classifying the document as topical on determining the probability of the document being topical to be greater than the probability of the document being anti-topical.

Abstract: A communication access control system includes a messaging service facility and a computing system. The computing system has a permanent memory and hosts a plurality of access control cells (each having an input and an output address); a messaging service to send messages between at least some of the access control cells; and a control service to define a link. The link is selected from a C-link, an F-link, and a Q-link. The C-link connects the output address of a first read-write cell of the access control cells to the input address of a second read-write cell of the access control cells. The F-link connects a forwarder address to the input address of at least one of the access control cells. The Q-link connects the output address of at least one of the access control cells to a queue address.

Abstract: Embodiments of the present invention provide a service access control system having a service object (110, 510) for providing services, a messaging service facility (120, 14, 520) and one or more spoke entities (140, 530, 540) for accessing services provided by the service object (110, 510) , wherein the messaging service facility (120, 14, 520) comprises one or more cells (210) each having an input address (220) and an output address (230), wherein at least one of the input address and the output address is linked to the other via a cryptographic key, the cell (210) (210) providing a message communication link between the spoke entity and a set of functions on the service object (110, 510) associated with the cell (210).
