Abstract: A method accesses information related to a reference entity through a display device. The method includes providing an ontology describing the reference entity and entities, the reference entity and the entities being classes of the ontology or being arranged into classes, the classes having respective properties; receiving information for identifying the reference entity; and calculating a network of entities out of the entities, the entities having relationships with the reference entity, according to the properties. The method further includes identifying portions available on an area of the display device, according to the classes of the ontology; assigning the entities to at least one of the display area portions; selecting a display area portion out of the display area portions; and displaying, on the display device, images and/or text data for indicating at least part of the entities of the network assigned to the selected display area portion.

Abstract: Elements of a database object are removed. The database object is stored as a plurality of different object portions, where each object portion is associated with one or more versions of transaction identifiers stored separately from the database object. An oldest transaction identifier is determined for a transaction for which data portions of the database object remains visible. Each object portion is examined and object portions with a threshold amount of data to remove are determined based on a comparison of the transaction identifiers for those object portions and the oldest transaction identifier. Data from the database object are removed in response to a sufficient quantity of data is to be removed from object portions containing the threshold amount of data.

Abstract: The disclosed embodiments disclose techniques for managing opportunistic locks in a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in the cloud storage systems; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem. During operation, a client sending a request to access a file from a cloud controller also requests an opportunistic lock for the file. If there are no other outstanding client accesses on the other cloud controllers that preclude the requested opportunistic lock, the cloud controller grants the client file access and the opportunistic lock.

Abstract: Systems and methods for managing state data from monitored entities in a computing environment are described. In a push-based approach, a publisher computer obtains state data of an element from the monitored entities and sends the state data on to a subscriber computer. From the state data, the publisher computer generates one metadata record for the element that is updated as newer state data is obtained such that each element is associated with just one record. The publisher computer scores and ranks the records of the elements based on a time since previous state data was sent to the subscriber computer, a magnitude of a change, and the existence of one or more event flags. The publisher computer schedules and queues the state data according to their ranking. The highest priority record in a queue is sent only when a timing signal indicates that state data can be sent.

Abstract: Regarding a management of data stored in a folder to which a permission range of access is set, a data management apparatus is caused to perform (a) a detection region setting step which sets a detection region for detecting a preliminary operation, which is for storing any data into a destination folder which can store data; and (b) a storing limitation step which limits the storing of the data into the destination folder in cases where the preliminary operation is detected at the set detection region, and the access permission range set for the destination folder is different from the access permission range set for a source folder storing the data originally.

In one embodiment of the invention, a data synchronization method can be provided to include assembling a group of initial updates for synchronization, consulting a synchronization log of updates excluded from past synchronizations to determine updates already applied during past synchronizations, removing updates already applied during past synchronizations from a filtered set of updates, and synchronizing the filtered set of updates. In this regard, assembling a group of initial updates for synchronization can include assembling a group of initial updates having a timestamp greater than a timestamp for an immediate past synchronization.

Abstract: In one example embodiment, a method is implemented to relink a data item. The method includes identifying that a data item, referenced by a referencing document, is absent from a data item location for the data item indicated by the referencing document. User preference data, indicating a designated relink location to search for absent data items, is accessed. The relink location is searched for the absent data items. Another example embodiment may include a method to relink a current data item to a replacement data item location by accessing user preference data and searching a relink location for a replacement data item in accordance with the relink location indicated by the user preference data.

Abstract: A method for performing block-level incremental backups of file system volumes using a pseudo device layer of a volume manager. A driver associated with a snapshot backup program is configured to back up the full pseudo disk upon receipt of a backup request, and not automatically performed upon startup. Incremental backups are performed thereafter using a driver that has been modified to include a monitor that tracks writes during backups. The standard I/O routine of the kernel is overwritten with an I/O routine that tracks write operations. The volume manager is called back to perform the incremental backup operations upon each write operation. The going down routine of the kernel is also overwritten to track any updates to the volume manager. If the volume manager is updated, the data structure is cleared and future backups are performed from a subsequent full backup.

Abstract: Techniques are provided for encoding/decoding binary XML data in a client program before sending/receiving the XML to/from a database server. By encoding the binary XML at the client, the overhead of parsing the XML text is avoided by the database server, thus improving database server scalability. Also, the XML data is sent by the server to the client in the binary form, and the binary format is decoded by the client program to perform the necessary operations.

Abstract: The World Wide Web (WWW) can be modelled as a labelled directed graph G(V,E,L), in which V is the set of nodes, E is the set of edges, and L is a label function that maps edges to labels. This model, when applied to the WWW, indicates that V is a set of hypertext documents or objects, E is a set of hyperlinks connecting the documents in V, and the edge-label function represents the anchor-text corresponding to the hyperlinks. One can find a probabilistic ranking of the nodes for any given label, a ranking of the labels for any given node, and rankings of labels and pages using flow based models. Further, the flows can be computing using sparse matrix operations.
