Abstract: One or more computing devices, systems, and/or methods for transmitting content items using search history profiles are provided. For example, a first request to access a web page may be received. The first request may be associated with a device. The first request may be analyzed to determine a query. The query may be stored in a search history profile associated with the device. The search history profile may comprise indications of a plurality of queries. A second request for content may be received from a second device associated with the search history profile. Responsive to receiving the second request, a content item may be selected from a content items database based upon the query. The content item may be transmitted to the second device. The device may be the same as the second device. Alternatively and/or additionally, the device may be different than the second device.

Abstract: Techniques are provided that include obtaining a Document Object Model of an HTML document, such as a web page of a publisher. Elements of the Document object model may be identified that are associated with native advertisement placement candidate containers. Based at least in part on analysis associated with the Document Object Model, and utilizing at least some of the identified elements, one or more native advertisement placement candidate containers may be determined. With some techniques, the analysis includes identifying a deepest set of nodes in the Document Object Model, corresponding to a particular tag sequence, whose cardinality is no less than a cardinality of a set of nodes in the Document Object Model, corresponding to a particular tag sequence, corresponding to the identified elements. Some techniques may utilize XPaths in the analysis.

Abstract: A presence system enables retrieval of calendar presence information of presentities from calendar servers using a calendar agent and calendar interfaces to the calendar servers. Each calendar server maintains calendar schedule information for one or more of the presentites. The calendar agent is operable to generate queries for the calendar schedule information to the calendar servers via a respective calendar interface for each calendar server. The calendar agent is further operable to receive calendar schedule information from the calendar servers via the respective calendar interfaces, and to convert the received calendar schedule information into calendar presence information. Each calendar interface is configured to communicate with the calendar agent via a first protocol and to communicate with a respective one of the calendar servers via a respective second protocol.
