Linking accounts corresponding to different products together to create a group so that group processing can be performed at the group level while independent processing of the accounts is performed at the account level. The method links the accounts into a group by linking a financial record for each account to group master data for the group. The group master data includes information about the group, including group parameters and a group identifier. A group typically includes a key account and one or more dependent accounts. The relationship between a dependent account and the group is specified by a dependent strategy. A dependent strategy specifies group level processing options for the account. The relationships between the accounts and the group are flexible to accommodate changes in the status of the group cardholders.

Enhanced links in a message composition surface are described. A uniform resource locator (URL) may be identified while a user is composing a message in a message composition surface of an electronic message such as an email. A source of the URL and the file type of the document linked to by the URL can be determined and a preview of the document can be rendered in the message composition surface. When the source is a cloud storage location, access permissions for the document can be adjusted from within email—without the user navigating to a file management site of the cloud storage. When the file type is a productivity application, a link rendering element can call a productivity application service to provide interaction functionality for the productivity application file and facilitate the rendering of the productivity application file.

Record Linkage (RL) is the task of identifying two or more records referring to the same entity (e.g., a person, a company, etc.). RL models can be based on Cost Sensitive Alternating Decision Trees (ADTree), an algorithm that uniquely combines boosting and decision trees algorithms to create shorter and easier-to-interpret linking rules. These models can be naturally trained to operate at industrial precision / recall operating points, and the shorter output rules are so clear that it can effectively explain its decisions to non-technical users via score aggregation or visualization. The models significantly outperform other baselines on the desired industrial operating points, and the improved understanding of the model's decisions led to faster debugging and feature development cycles.

A computer on which an SIP message delivery program is running stores records for respective entities of an SIP message that contains location information into a table in a storage device. Each record links virtual host identifying information to identify a virtual host that receives an SIP message only when the entities contain predetermined location information with the predetermined location information that is a content of the receipt condition. The computer receives an SIP message from an SIP server on a network, and searches the table for a record whose receipt condition in an entity matches location information in the corresponding entity in the received SIP message, for each of entities in a predetermined order. When a record is detected, the computer delivers the received SIP message to the virtual host that is distinguished by the virtual host identifying information included in the detected record.
