Abstract: Reductions to bandwidth storage resource use needed to safely and securely provide longitudinal data related to individuals to authorized parties from disparate sources are realized by employing the present disclosure. As the data related to the individual are held by various originating and aggregating databases in a variety of formats, with each database having different sharing policies, and the user similarly specifying different access permissions to personal data, a hub that manages access in a hybrid distributed/aggregated mode enables requestors to review data at a single point of access in accordance with specified access permissions from the databases or the individual. Reduced weight records, using permitted data fields, are aggregated and links to the records are provided according to the determined permission levels.

Abstract: The present disclosure is directed to dynamically determining the breadth of user intent reflected in a given search query. For example, historical user behaviors are used to construct a mapping that links particular search queries (or their constituent keyword strings) to items that users interact with during a predetermined window of time after submitting the query. The number of categories or browse nodes associated with these items (or a most popular subset thereof) is used to determine whether the search intent is broad or narrow. For broad searches, the present disclosure causes output of a specialized user interface that facilitates browsing of items in the browse nodes or categories, in place of the typical search results user interface.

Abstract: A media content tagging system includes a computing platform having a hardware processor, and a system memory storing a tag selector software code configured to receive media content having segments, each segment including multiple content elements each associated with metadata tags having respective pre-computed confidence scores. For each content element, the tag selector software code assigns each of the metadata tags to at least one tag group, determines a confidence score for each tag group based on the pre-computed confidence scores of its assigned metadata tags, discards tag groups having less than a minimum number of assigned metadata tags, and filters the reduced number of tag groups based on the second confidence score to identify a further reduced number of tag groups. The tag selector software code then selects at least one representative tag group for a segment from among the further reduced number of tag groups.

Abstract: A method uses natural language processing for visual analysis of a dataset by a computer. The computer displays a data visualization based on a dataset retrieved from a database using a set of one or more queries. The computer receives user input (e.g., keyboard or voice) to specify a natural language command related to the displayed data visualization. Based on the displayed data visualization, the computer extracts one or more independent analytic phrases from the natural language command. The computer further computes semantic relatedness of extracted analytic phrases, and computes analytical functions associated with the extracted analytic phrases, thereby creating functional phrases. The computer requeries the database using an updated set of one or more queries based on the created functional phrases, thereby retrieving an updated dataset. The computer then displays an updated data visualization using the updated dataset.

Abstract: The present disclosure involves analyzing data relevancy of particular fields within one or more databases in a big data system. In one example method, an interaction with at least one of a plurality of monitored data sources is identified, wherein the identified interactions is associated with a particular field of a database table of one of the monitored data sources. A set of data associated with the interaction is determined which includes an identification of each field associated with the identified interaction and a count of a number of interactions associated with each particular field. A relevancy index table is updated to include the determined set of data, wherein each identified field is associated with a row in the index table. At least one relevancy rule is identified for the relevancy index table and is executed to generate a relevancy score for at least one of the fields.

Abstract: In an example, data from a source location is merged into a target location containing existing data, in which the source location and the target location contain tuples of data. For each tuple in the source location, during a single operation, a determination is made as to whether there is a matched tuple in the target location that satisfies a predetermined condition. For each matched tuple that satisfies the predetermined condition, the matched tuple in the target location is updated with a count value that is equal to a count of the matched tuple in the source location and the target location. In addition, for each tuple that does not have a matched tuple that satisfies the predetermined condition, the unmatched tuple is inserted into the target location.

Abstract: Data stream quality management for analytic environments includes deploying, into a runtime environment upstream from an analytic module, an ingress quality specification (IQS) module. The IQS module receives a data stream and analyzes a subset of data of the data stream to determine if the subset of data meets a quality expectation of the analytic module. The subset of data is annotated to indicate a quality status based on whether the subset of data meets the quality expectation of the analytic module. The data stream is output with the annotated subset of data to the analytic module, and the analytic module analyzes the data stream to assess an operating characteristic of an upstream device.

Abstract: Software for a website hosting a content-aggregation service generates a first representation of interests for a user. The first representation includes a plurality of entities including pivot entities and extended entities, where the extended entities result from a nearest-neighbor search of word embeddings. Each of the extended entities is associated with a nearness score that is weighted using a distance of the extended entity from one of the pivot entities. For each of a plurality of articles ingested by the content-aggregation service, the software generates a second representation that associates an aboutness score with each of the plurality of entities. The software uses the first representation, a similarity measure, and the second representations to create rankings of the plurality of articles. The software receives a request for access to the content-aggregation service from the user and serves the user a content stream based at least in part on the rankings.
