Abstract: Examples of the disclosure enable generating, maintaining, and/or updating a model configured to identify content for a segment. In some examples, a plurality of keywords associated with accessing webpages are retrieved. A plurality of keyword scores corresponding to the keywords are generated. Based on the keyword scores, a subset of keywords are identified as being associated with the segment. The subset of keywords are compared with content keywords associated with content to determine whether to include the content in a subset of content associated with the segment. Users associated with the subset of content are identified. Based on metrics associated with the users, the users are labeled for generating a training set associated with the segment. Aspects of the disclosure enable a predictive model to be generated, maintained, and/or updated in a calculated and systematic manner for increased performance.

Abstract: A data mapping architecture for mapping between two or more data sources without modifying the metadata or structure of the data sources themselves. Data mapping also supports updates. The architecture also supports at least the case where data sources that are being mapped, are given, their schemas predefined, and cannot be changed. The architecture includes a mapping component that receives respective metadata from at least two arbitrary data models, and maps expressions between the data models.

Abstract: The present invention relates to a system and methodology to facilitated data object persistence. An object schema is utilized to provide metadata for types in addition to what is provided by the type system for an underlying programming language. This metadata is then utilized by the system to translate data to and from user objects during a materialization or persistence process. The object schema provides information external to programming logic and type definitions. Consequently, the object schema can be deployed independent of an application thereby allowing the persistence storage of user objects to change without force the user to recompile and deploy application code.
