Abstract: A user device displays portions of an electronic publication for a user to read. The user device tracks the user's reading behavior of the portions of the electronic publication. The user device then suggests additional reading material for the user based on the user's reading behavior.

Abstract: Electronic content items such as electronic books are enhanced by identifying citations within the content items, identifying sources of the objects of the citations, and associating the citations with such sources so that readers of the content items can easily purchase or otherwise obtain the citation objects. The citations may be updated as new products become available or information related to the products changes over time.

Abstract: A user device displays portions of an electronic publication for a user to read. The user device tracks the user's reading behavior of the portions of the electronic publication. The user device then selects a problem from a group of pre-generated problems for the user based on the user's reading behavior and provides the selected problem to the user.

Abstract: In-line secondary transaction is described. In an embodiment, an on-line shopping interface is displayed via which an item can be selected for purchase. When a selection is received to initiate a purchase of the item, a determination is made that a secondary transaction is needed to complete the purchase of the item. An in-line secondary transaction user interface is displayed over a portion of the on-line shopping interface to facilitate the secondary transaction where the in-line secondary transaction user interface is displayed to maintain a context of the purchase on the on-line shopping interface. An input of transaction information is received via the in-line secondary transaction user interface to complete the secondary transaction such that the purchase of the item can be completed via the on-line shopping interface.

Abstract: A system and method facilitating network diagnostics and self-healing is provided. The invention includes a data stream monitor component adapted to selectively copy protocol specific subset(s) of raw network data and provide the subset(s) of data to a diagnostics engine. The invention further includes a diagnostic engine adapted to facilitate network diagnostics and/or self-healing. The invention further provides for protocol state compressor(s) to analyze the protocol specific subset(s) of data to abstract and/or analyze relevant information about the specific protocol without having to strictly process the protocol or preserve protocol state variable(s) in order to analyze the state of the specific protocol. Based upon this analysis, the protocol state compressor(s) can generate event(s) for undesirable state(s) (e.g., error(s) and/or failure(s)) and/or congested state(s) for use by the event correlator/inference engine.
