Abstract: While discharging a data chunk, the chunk is compressed into a storage block. If the chunk is found to be too large to be able to be completely compressed into the storage block, certain characteristics of the data chunk are examined to determine whether or not the data chunk should be split. If the data chunk should be split, a remaining portion of the data chunk is compressed to a storage block that is next in chronological order to the original storage block. If the data chunk should not be split, all of the data chunk is moved to the next chronological storage block while leaving any remaining space in the storage block as unused.

Abstract: A system, method, and medium for performing incremental backups of a Microsoft SQL server database. A snapshot of the database is created, and then a map identifying the changed extents is retrieved from the snapshot. The changed extents are then retrieved from the snapshot and stored in a backup storage device. For a restore operation, a full database backup file is written to a storage device and then the changed extents from a stored incremental backup file may be merged with the full backup file. Next, the database server is notified of the reconstructed file and then the reconstructed file is mounted by the database server as a live instance of the database.

Abstract: According to embodiments of the present invention, one or more computer processors determine that a predetermined workload threshold associated with an invalidated object is not exceeded and transmits an invalidation command associated with the invalidated object to the owner of the invalidated object. The one or more computer processors instruct the modifier of the invalidated object to retain possession of a first lock on the object beyond the transaction. The one or more computer processors determine that a usage pattern associated with the invalidated object matches a predetermined usage pattern for selecting a lock that can be retained beyond an associated transaction and transmits a second lock a requestor. The one or more computer processors instruct the modifier to release possession of the first lock to the owner and transmit a first image of the current version of the invalidated object to the owner for subsequent transmission to the requestor.

Abstract: Mechanisms are provided, in a question and answer (QA) system, for monitoring changes in answers to previously submitted questions. A question is received for which an answer is to be generated. One answer for the question is generated and the question, answer, and a notification party are registered in a question registration data structure. Another answer to the question is generated, at a later time than when the previous answer was generated. A degree of a change in the two answers to the question is determined. An answer change notification is transmitted to the notification party based on the degree of the change in the two answers to the question. The notification party may be the source of the question or a registered party to which notifications are to be sent.

A hypertext link to the identified location of the search term within the ML document is configured.

Abstract: A query of spatial data is received by a database comprising a columnar data store storing data in a column-oriented structure. Thereafter, a minimal bounding rectangle associated with the query is identified using a tree-order scanning technique. A spatial data set that corresponds to the received query is then mapped to the physical storage in the database using the identified minimal bounding rectangle. Next, the spatial data set is then retrieved. Related apparatus, systems, techniques and articles are also described.

Abstract: Content object tags at a content hosting service are used to classify stored content objects. Tags and clusters of tags (groups of one or more associated tags) can be recommended to a user of the content hosting service based on a user context, such as the browsing, viewing, uploading, or searching of content objects. Tags are scored based on content objects tagged with the tags in a targeted subset of content objects and a baseline subset of content objects, and based on the relevance of the content objects tagged with the tags. These tag scores can be weighted, and one or more tags can be selected for recommendation based on the weighted tag scores. Tag clusters can be selected for recommendation using a cluster hierarchy and determining whether a targeted subset of tags occur within a maximum number of tag clusters at a particular hierarchy level.

Abstract: One or more mobile devices make measurements while moving along a path. Each measurement may comprise a specific group of identifiers of wireless transmitters, and strengths of corresponding wireless signals. A set of measurements are made in a sequence along a path, and the subsets of the measurements are identified for satisfying a test on a value of a measure of similarity of measurements included in the subset. A new place of relevance is identified, by comparing the just-described subsets of the measurements with similar subsets of additional measurements (e.g. by clustering). Alternatively, a known place of relevance (e.g. having a label) is identified, by comparing the just-described subsets of the measurements with pre-computed model of measurements. Also, the just-described subsets of the measurements may be compared with corresponding subsets of measurements of another path, e.g. to identify common portions therein.
