International Classification:

G06F 1730

US Classification:

707 7

Abstract:

A method and system for evaluating the relevancy of an incoming message to a plurality of users are disclosed. Similarity scores indicating similarities of the incoming message to features of a plurality of messages are generated. Relevancy scores are generated for the plurality of users indicating relevancies of the incoming message to the plurality of users based on the similarity scores and a plurality of user profiles including information descriptive of the plurality of users preferences for the features.

Abstract:

A method and apparatus for providing information to a plurality of users based on the relevancy of the information to the users are disclosed. An incoming message is received. Similarity scores are generated indicating similarities of the incoming message to features of a plurality of messages. Relevancy scores are generated for the plurality of users, the relevancy scores indicating relevancies of the incoming message to the plurality of users based on the similarity scores and a plurality of user profiles including information descriptive of the plurality of users preferences for the features of the plurality of users. Message information derived from the incoming message, the relevancy scores, and the plurality of user profiles is delivered to at least some of the plurality of users.

Abstract:

An archive cluster application runs in a distributed manner across a redundant array of independent nodes. Each node preferably runs a complete archive cluster application instance. A given nodes provides a data repository, which stores up to a large amount (e. g. , a terabyte) of data, while also acting as a portal that enables access to archive files. Each symmetric node has a set of software processes, e. g. , a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests to the node for data (i. e. , file data), the storage manager manages data read/write functions from a disk associated with the node, and the metadata manager facilitates metadata transactions and recovery across the distributed database. The policy manager implements one or more policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage.

Abstract:

A file protection scheme for fixed content in a distributed data archive uses computations that leverage permutation operators of a cyclic code. In an illustrative embodiment, an N+K coding technique is described for use to protect data that is being distributed in a redundant array of independent nodes (RAIN). The data itself may be of any type, and it may also include system metadata. According to the invention, the data to be distributed is encoded by a dispersal operation that uses a group of permutation ring operators. In a preferred embodiment, the dispersal operation is carried out using a matrix of the form [IC] where Iis an n×n identity sub-matrix and C is a k×n sub-matrix of code blocks. The identity sub-matrix is used to preserve the data blocks intact. The sub-matrix C preferably comprises a set of permutation ring operators that are used to generate the code blocks.

International Classification:

US Classification:

707797

Abstract:

A versioned file system comprises a set of structured data representations. At a first time, an interface creates and exports to a data store a first structured data representation corresponding to a first version of a local file system. The first structured data representation is an XML tree having a root element, one or more directory elements associated with the root element, and one or more file elements associated with a given directory element. Upon a change within the file system (e. g. , file creation, file deletion, file modification, directory creation, directory deletion and directory modification), the interface creates and exports a second structured data representation corresponding to a second version of the file system. The second structured data representation differs from the first structured data representation up to and including the root element of the second structured data representation. The data store may comprise a cloud storage service provider.
