Abstract: Architectures and techniques are presented that can more efficiently update derived data products in response to updated source data. Source data is typically stored in source tables, whereas a materialized view of a query can generate a derived table based on the state of the source tables at the time the query is executed. When source data changes (e.g., in response to late-arriving input data), rather than recomputing the entire derived table (e.g., by again executing the original query, which can be expensive), an invertible relationship between timestamps can be leveraged to identify only those portions of the derived table that are affected by the update. Therefore, a new defining query can be generated to update only those portions of the derived table that are affected by the source data update.

Abstract: Systems and methods utilize a data model database which includes a plurality of symbol data types. Each of the plurality of symbol data types have one or more symbol data fields. The data model database further includes a plurality of concrete data types. Each of the concrete data types have one or more language-agnostic concrete fields associated with each of the one or more symbol data fields. Each of the one or more language-agnostic concrete fields apply one or more concrete constraints to each of the corresponding symbol data fields. The data model database further includes a plurality of carrier data types. The plurality of carrier data types having one or more language-specific carrier fields associated with each of the one or more language-agnostic concrete fields. Each of the one or more language-specific carrier fields apply one or more carrier constraints to each of the corresponding language-agnostic concrete fields.

Abstract: A method and apparatus for enriching metadata are disclosed. For example, the method implemented via a processor monitors metadata associated with a first webpage of a plurality of webpages, the first webpage having been determined to be similar to a second webpage of the plurality of webpages, detects a change to the metadata associated with the first webpage, determines whether the change to the metadata associated with the first webpage invokes an update to a metadata associated with the second webpage, and processes the update of the metadata associated with the second webpage when the change invokes the update to the metadata associated with the second webpage.

Abstract: Aspects of the subject disclosure may include, for example, embodiments include receiving first user-generated input from a recruiter device. The recruiter device is associated with a manager of a group. Further embodiments include generating a first smart contract between an applicant and the manager according to the first user-generated input. The generating of the first smart contract comprises generating the first smart contract on a blockchain. Additional embodiments can include providing the applicant access to the group according to the first smart contract, receiving second user-generated input from the recruiter device, and generating a second smart contract between a record keeper and the manager according to the second user-generated input. The generating of the second smart contract comprises generating the second smart contract on the blockchain. Also, embodiments can include providing the record keeper access to the group according to the second smart contract. Other embodiments are disclosed.

Abstract: Recommendation systems are widely used in Internet applications. In current recommendation systems, users only play a passive role and have limited control over the recommendation generation process. As a result, there is often considerable mismatch between the recommendations made by these systems and the actual user interests, which are fine-grained and constantly evolving. With a user-powered distributed recommendation architecture, individual users can flexibly define fine-grained communities of interest in a declarative fashion and obtain recommendations accurately tailored to their interests by aggregating opinions of users in such communities. By combining a progressive sampling technique with data perturbation methods, the recommendation system is both scalable and privacy-preserving.

Abstract: A system for providing continuous monitoring of data quality in a dynamic feed environment is disclosed. In particular, the system utilizes a feed inspection tool to detect anomalies in data gathering detected from feed metadata and anomalies in data measurement detected based on file contents. In order to do so, the feed inspection tool may aggregate, for a plurality of aggregation intervals, data feeds and associated metadata feeds. Once the data feeds and metadata feeds are aggregated, the feed inspection tool may generate, for a baseline model feed, baseline statistical models by utilizing historical data of the aggregated feeds in sliding windows of different lengths. The feed inspection tool may then identify, for a plurality of monitoring time delays, data outliers by comparing the aggregated feeds with the baseline model feed. A data quality feed based on the data outliers identified may then be generated and published.
