Abstract: This invention relates to a computer-based method and apparatus for facilitating the retrieval, classification, and distribution of information. In one embodiment, a method for providing information relating to a topic comprises specifying a first and second topic, specifying a relationship between the two topics, receiving a first and second piece of information, associating the first piece of information with the first topic and the second piece of information with the second topic, requesting information associated with the first topic, and receiving the information associated with the first and second topics.

Abstract: This invention relates to a computer-based method and system for facilitating the retrieval, classification, and distribution of information. In one embodiment, a method for providing information comprises providing a plurality of entities, each having an entity type, providing a plurality of relationships among the entities, each relationship having a relationship type and direction, and constructing an entity-relationship network comprising the entities and relationships. The method further includes receiving a plurality of information items, facilitating the association of the information items with at least one corresponding entity, receiving a request for information items associated with a selected one of the entities, determining a subset of the entities based on the selected entity, the relationships, the relationship types and the relationship directions, and providing the information items associated with the subset of the entities.

Abstract: A clustered computer system includes a shared data storage system, preferably a virtual shared disk (VSD) memory system, to which the computers in the cluster write data and from which the computers read data, using data access requests. The data access requests can be associated with deadlines, and individual storage devices in the shared storage system satisfy competing requests based on the deadlines of the requests. The deadlines can be updated and requests can be killed, to facilitate real time data access for, e.g., multimedia applications such as video on demand.

Abstract: A method and system for calculating an environmental score are described and generally related to calculating a score for a separately accountable business unit, where the score is indicative of external costs for the business unit. A computer system for calculating a score for a separately accountable business unit, the score being indicative of a level of unaccounted for external environmental cost of economic activities of the separately accountable business unit, the system includes accessing means for accessing accounts data indicative of recognized costs for the separately accountable business unit, accounts processing means for processing the accounts data by adding external environmental costs to the recognized costs and for calculating the score for the separately accountable business unit using the processed accounts data.
