Abstract: A method comprising: generating, by a computing system, a change graph that represents a change to an ontology graph; generating, by the computing system, an impact score for the change graph by applying at least one of a deterministic rule and a machine learning technique to the change graph; and outputting, by the computing system, the change graph and the impact score for the change graph to a subscriber system.

Abstract: The present invention is a method and apparatus for first integrating the operation of various independent software applications directed to the management of information within an enterprise. The system architecture is, however, an expandable architecture, with built-in knowledge integration features that facilitate the monitoring of information flow into, out of, and between the integrated information management applications so as to assimilate knowledge information and facilitate the control of such information. Also included are additional tools which, using the knowledge information enable the more efficient use of the knowledge within an enterprise, including the ability to develop a context for and visualization of such knowledge.

Abstract: A non-volatile memory module includes a charging circuit, a battery couple to the charging circuit, a volatile memory and an electronic switch coupled between the volatile memory and the battery.

Abstract: An XOR controller which is capable of performing the XOR operations necessary to generate a new parity value corresponding to new data being written to a disk storage device from a host computer without the intervention of the storage subsystem microprocessor. In one embodiment the storage subsystem microprocessor controls the loading of the new data from the host and old data and parity from a disk storage device into cache memory, if such data is not already in cache memory, and creates the appropriate data structures. The storage subsystem microprocessor then loads the XOR controller with a pointer to a table in cache memory containing information needed by the XOR controller to perform the XOR operations. The XOR controller, upon completion of the XOR operations on all the data, informs the storage subsystem microprocessor of such completion. Thereafter, the microprocessor causes the new data and new parity to be written to the disk storage device from the cache memory.

Abstract: A controller capable of performing the flexible addressing of memory modules. In one embodiment, involving cache memory, a cache controller maintains, for each slot in cache memory, a read base address and a write base address for the slot and certain characteristics of the SIMM residing in the slot. The use of separate write and read addresses permits more than one cache memory SIMM to be written to with a single write address and permits cache memory to be non-contiguous and thus more robust with respect to SIMM failures. The maintenance of a table of SIMM characteristics permits volatile and non-volatile SIMMs to be used together in cache memory.
