Interactive virtual conversation interfaces are provided herein. An example method includes receiving a digital document that has textual information, utilizing one or more forms natural language processing of the digital document, based on the nature of the digital document, to ascertain a hierarchical structure of the plain textual information, and determine topics within the plain textual information, generating a tree structure based on relationships between topics of the plain textual information, wherein the topics are arranged into the tree structure, and generating a virtual conversation interface that receives queries and presents responses to the queries using the tree structure.

A method for securing messages includes obtaining, at a message server, a message for a user of a message service hosted by the message server. The message includes a header and the header includes a digital signature signed by an author of the message and a list of one or more recipients of the message. The method includes determining whether the digital signature by the author is valid and determining, using the list of one or more recipients, whether the user is a declared recipient of the message. When the digital signature by the author is valid and the user is the declared recipient of the message, the method includes delivering the message to a user device of the user. When the digital signature by the author is valid and the user is not the declared recipient of the message, the method includes alerting the user.

In one aspect, a device may include at least one processor and storage accessible to the at least one processor. The storage may include instructions executable by the at least one processor to identify a first email, identify a second email different from the first email, determine that the first and second emails are related, and move content from at least one of the first and second emails into a third email responsive to the determination. Present principles may also apply to other electronic message types besides emails.

Systems and methods for altering tablature via geographical interfaces are disclosed. A system may include at least one processor configured to output a first signal for rendering a table, including a plurality of items, columns, and values in cells, wherein one of the columns may retain geographic location values, wherein a subgroup of the items may share a common geographic location value. The processor may output a second signal to render a common map, including markers associated with the geographically dispersed items, enable an interaction with the common map, output a third signal to render column values associated with the plurality of items of the subgroup, receive a fourth signal to update a column value for a particular item, receive a fifth signal to re-render the table, and output a sixth signal to re-render the table, wherein the sixth signal includes the updated value for the particular item.

Systems and methods are described for providing an email assistant options bar. An assistant engine of an email application can identify contacts of a user profile that the user interacts with the most frequently based on a set of rules. When a user interacts with an email in the email application using a predetermined input type, the assistant engine can display the email assistant options bar. The email assistant options bar can include icons representing the identified contacts that the user interacts with the most frequently and a set of actions that can be performed to interact with the contacts. Some examples of actions can include forwarding the selected email, calling a contact, and setting up a meeting. The user can select one or more of the contacts and one of the actions. The assistant engine can perform the selected action with the selected contact as the recipient.

Certain embodiments enable application message delivery to be automatically guaranteed for all failover scenarios through use of a novel infrastructure layer that supports high availability (HA) messaging. The High Availability Application Messaging Layer (HAML) can guarantee delivery of application messages whether a failover occurs at one or both of the source and the intended destination of the message. The HAML may transmit messages to one intended destination, as unicast messaging, or to multiple intended destinations, as multicast messaging. In some embodiments, the HAML may be HA aware, which refers to the awareness of the HAML of the redundancy for all processing entities within a network device to ensure hitless failover at the network device. By moving support for HA messaging from individual applications to the HAML, as a common infrastructure layer across the processing entities, the individual applications do not need to implement additional software to explicitly support HA messaging.

Systems, methods, and related technologies are provided for generating interactive emails and tracking user interactions. In one implementation, an email an be received within an email client. The email can be rendered within the email client, such as by: presenting a first selectable element within the email client, presenting a second selectable element within the email client, and presenting one or more content items within the email client. A selection of the first selectable element can be received within the email client. In response to the selection of the first selectable element, a presentation of the one or more content items can be adjusted within the email client.

The subject technology receives metadata corresponding to a respective media overlay, the metadata including information indicating that the respective media overlay is configured to be applied as an image processing operation during post-processing of image data during a post-capture stage. The subject technology selects the respective media overlay in response to the information indicating that the respective media overlay is configured to be applied as an image processing operation during post-processing of image data. The subject technology, based at least in part on a category indicator associated with the respective media overlay, populates a group of media overlays with at least the respective media overlay. The subject technology sends, to a client electronic device, second metadata including at least information related to the group of media overlays.
