Abstract: A flow control technique prevents exhaustion of storage resources in an exactly once semantics (EOS) system of a storage input/output stack executing on a node of a cluster. An EOS server may service transactions sent by an EOS client and issue replies with results to the EOS client. In order to replay the transactions during normal operation after recovery from a crash, the EOS server persistently stores the transactions in the storage resources until an acknowledgement of completion is received from the EOS client for each pending transaction. The EOS client may issue a checkpoint acknowledgement, e.g., as a prune record, after a periodic interval that marks the completion of all pending transactions issued prior to the record. The EOS server need only log the prune record (rather than each pending transaction) to thereby prevent exhaustion of the storage resources, while also minimizing logging overhead of the server.

Abstract: The present disclosure provides for analyzing data stored in a data protection storage system to determine a prospective storage scheme that provides a more efficient use of storage resources in the data protection storage system. Data can be analyzed to identify a set of data suitable for long term storage in an archive. Data can be analyzed to identify a set of data suitable for deletion to reduce duplicate copies of data, and remove expired data. Protection policies that provide double coverage of data, causing additional inefficient storage of data, can be identified. A prospective amount of freed storage and other savings can be calculated, if all or part of the prospective storage scheme is implemented, where the prospective amount of freed storage and other savings can be displayed to in a report. A prospective storage scheme may also be determined for a client system that stores live data.

Abstract: A computer-implemented method for indexing backup file metadata may include 1) identifying a request to perform a full backup of a volume, 2) identifying a file metadata index for previous backups of the volume, 3) adding a current key uniquely identifying the file within the full backup and an identifier of the full backup to the file metadata index, 4) comparing the current key to the file metadata index to determine whether the current key is represented in the file metadata index, and 5) adding file metadata to the file metadata index for each file within the volume that is uniquely represented by the current key of the file within the file metadata index. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Systems and methods that enable removal of data from an endpoint, while not propagating such removal to other endpoints when synchronizing data sources associated therewith. A designation component can indicate items as forgotten items, wherein such items are being known to an endpoint and deleted therefrom—yet, reintroduced therein and reappearing (e.g., as a create) upon re-synchronizing with the replica over again. Moreover, the forgotten items can employ additional metadata such as in from of an additional bit that indicates whether an item is a forgotten item.

Abstract: An audience selection system for the selection of an entity, based on an entity's consumption history without requiring the storage of a content descriptor for identifying content previously accessed by the entity. By directly and/or indirectly observing the usage of words used to locate content through a search engine over time for a population, a list of depersonalized keywords can be discovered, creating the ability to characterize content based on depersonalized keywords. A protected consumption history can be recorded for an entity using depersonalized keywords instead of recording a content descriptor for identifying the content. Depersonalized keywords do not uniquely identify content. Associating depersonalized keywords with an entity does not mean that the entity has used those depersonalized keywords; it only means that the entity has accessed content which has been accessed in the past by other entities in a population using the depersonalized keywords.

Abstract: A system, method and computer program product for archiving image, audio, and text data with metadata encapsulation in a client-server storage library is described. The server receives and holds the images, audio, or text to be archived in an image, audio or text logical partition which includes a directory of the images, audio, or text. The information is encapsulated in a metadata wrapper and stored in the library as a closed image, audio, or text file along with a closed copy of the directory. The closed image, audio, or text directory is also stored in the client. The images may be encapsulated in MXF, DICOM, Tape Archive (TAR) or GZIP formats. The storage library may have magnetic tapes, magnetic disks or optical disks as storage media.

Abstract: A search request for medical content can be initiated by a user, and the medical content that is relevant to the search request can be identified. The identified medical content can be ranked based on the number of times the content has been referenced as well as by the healthcare provider that referenced the medical content. The relevant identified medical content can then be displayed in an ordered list that is ordered based on the number of times the content has been assigned.

Abstract: The present disclosure includes techniques pertaining to computer implemented systems and methods for processing semi-structured data. In one embodiment, semi-structured data in a data source is analyzed and structural information about the data is generated. The semi-structured documents may comprise a plurality of fields having associated values. Documents may be analyzed to determine particular fields in the plurality of semi-structured documents. Statistics may be generated to determine, for example, a frequency that each particular field appears in the plurality of semi-structured documents. Particular fields and associated frequencies and other statistics may be stored in a memory, for example.

Abstract: Presented herein are methods of replicating versioned and hierarchical data structures, as well as data structures representing complex transactions. Due to interdependencies between data entities and a lack of guaranteed message ordering, simple replication methods employed for simple data types cannot be used. Operations on data structures exhibit dependencies between the messages making up the operations. This strategy can be extended to various types of complex transactions by considering certain messages to depend on other messages or on the existence of other entries at the data store. Regardless of origin, these dependencies can be enforced by suspending the processing of messages with unsatisfied dependencies until all of its dependencies have been met. Alternately, transactions can be committed immediately, creating entities that include versioned identifiers for each of their dependencies. These entities can then be garbage collected of the parent objects are not subsequently created.

Abstract: Method, system, and programs for providing enhanced query term suggestions. Candidate query terms may be obtained based on a prefix of incomplete query terms received. The candidate query terms may be ranked, at least partially based on, their similarities with respect to query terms previously entered in the same search session as the incomplete query term. In some implementations, for determining such similarities, feature vectors and/or signatures may be stored in association with query terms. Similarity between a candidate query term and query terms in the same search session as the incomplete query term may be determined using the feature vectors and/or signatures associated therewith.

Abstract: A computer implemented system and method for selecting and notifying operators of the option to enable a record activation feature for a short interval of time for the records they offer in a selected geographic area. Enabling record activation for a record indicates that the record may be booked by a user without first requesting the operator to manually approve the transaction request and waiting for the operator's approval of the request. Before selecting and notifying operators, a demand for database requests is predicted. Operators that are most likely to offer their record for record activation are identified. A quality score is determined for each identified record based on the likelihood that the record will get booked once the operator has programmatically enabled record activation. The records needed to fulfill the demand for database requests are selected based on their quality score and the operators of the selected records are notified of the option to enable record activation.

Abstract: Disclosed aspects relate to managing a stream computing environment using a projected database object. A set of realized data of a realized database object of a database management system (DBMS) may be compared with a set of projected data of a projected database object of the DBMS. The set of realized data of the realized database object and the set of projected data of the projected database object may be compared with respect to the DBMS that relates to the stream computing environment. An outlier subset of the set of projected data may be identified based on comparing the set of realized data with the set of projected data. Based on the outlier subset of the set of projected data, an outlier response action may be executed in the stream computing environment.

Abstract: A process is described for assessing the suitability of particular keyword phrases for use in serving contextually relevant content for display on pages of network-accessible sites. In one embodiment, the process involves scoring the key phrases based in part on collected user behavioral data, such as view counts of associated social media content items. A process is also disclosed in which selected keyword phrases on a page are transformed into links that can be selected by a user to view bundled content that is related to such keyword phrases.

Abstract: Described herein are computer-implemented systems and methods for automatically disambiguating author names for a plurality of publications so as to create clusters of author name mentions that are with high probability associated with a single author identity for each cluster. Also described are systems and methods for assigning the clusters to respective unique author identities, automatically and/or based on human input (e.g., as received from authors, co-authors, or administrative curators).

Abstract: A method operates an infotainment system in order to provide an overview of audio data records detected by a music output device. An evaluation device arranges the detected audio data records into an audio data record group according to a selection criterion, e.g. the artist. The evaluation device determines a value of a predetermined user-relevant evaluation variable for each audio data record. On the basis of the respective values, the evaluation device then determines a ranking list of the audio data records in each audio data record group. The evaluation device generates a digital image for each audio data record and assigns the images of those audio data records that are combined into an audio data record group to an image group. The position of the images in an image group depends on the position of the respective associated audio data record in the ranking list.

Abstract: In general, the invention relates to a method and system for migrating tables in databases. The method may include calculating a first plurality of migration factors for a first set of tables in a source database using a plurality of pre-calculated factors and a first plurality of dynamically-calculated factor, where each of the first plurality of migration factors is associated with one of the first set of tables. The method may further include selecting a first table from the first set of tables to migrate based on the first plurality of migration factors; and migrating the first table to a target database.

Abstract: A database language (e.g. SQL) is extended to define a transient field whose value is derived from data stored in a database. The value of the transient field is calculated by the database engine for consumption as needed by the application layer, for example as part of a particular data model. The value of the transient field may not be materialized as a persistent field in the underlying database table, or may be selectively materialized based upon a heuristic or hint. Certain embodiments may implement the transient field as a basic elaboration on standard SQL utilizing an identifier. Some embodiments may implement the transient field as an entity where SQL has been extended to accommodate concepts of a higher-level Entity Relationship Model (ERM). The use of constants and/or floating values (e.g. a current time) in connection with transient fields, is also disclosed.

Abstract: Disclosed aspects relate to managing a stream computing environment using a projected database object. A set of realized data of a realized database object of a database management system (DBMS) may be compared with a set of projected data of a projected database object of the DBMS. The set of realized data of the realized database object and the set of projected data of the projected database object may be compared with respect to the DBMS that relates to the stream computing environment. An outlier subset of the set of projected data may be identified based on comparing the set of realized data with the set of projected data. Based on the outlier subset of the set of projected data, an outlier response action may be executed in the stream computing environment.

Abstract: Embodiments for data deduplication of an initial snapshot of a data set in a storage system by a processor. An intra-snapshot similarity index, inclusive of representations of the data inside the initial snapshot, is built. The intra-snapshot similarity index is used for deduplication of the initial snapshot. The intra-snapshot similarity index is merged with a global similarity index.
