Methods, programs (120) and apparatus (100) are disclosed for accessing and heterogenous data sources (150-153) and presenting information obtained therefrom. Specifically, the data sources may have hierarchical data, which may be presented by identifying a context data node from the data, the context data node having one or more descendent data nodes. At least one data pattern is determined in the descendent data nodes. At least one display type is assigned to the current context data node on the basis of the at least one data pattern. Thereafter, the method presents at least a subset of the descendent data nodes according to one of the assigned display types. Also disclosed is a method of browsing an hierarchically-represented data source. A user operation is interpreted to identify a context data node from the data source, the context data node having one or more descendent data nodes. At least one data pattern in the descendent data nodes is then determined and at least one display type is assigned to the current context data node on the basis of the at least one data pattern. A subset of the descendent data nodes is then presented according to one of the assigned display types, the subset including at least one hyperlink (3401,3402) having as its target a descendant data node of the current context data node. A further user operation is then interpreted to select the at least one hyperlink, the selection resulting in the current context data node being replaced with the data node corresponding to the target of the selected hyperlink. These steps may be repeated until no further hyperlinks to descendent data nodes are included in the subset. Other methods associated with access and presentation are also disclosed.

Embodiments of the present disclosure provide a method and system for implicitly authenticating a user to access controlled resources. The system receives a request to access the controlled resources. The system then determines a user behavior score based on a user behavior model, and recent contextual data about the user. The user behavior score facilitates identifying a level of consistency between one or more recent user events and a past user behavior pattern. The recent contextual data, which comprise a plurality of data streams, are collected from one or more user devices without prompting the user to perform an action explicitly associated with authentication. The plurality of data streams provide basis for determining the user behavior score, but a data stream alone provides insufficient basis for the determination of the user behavior score. The system also provides the user behavior score to an access controller of the controlled resource.

A method for constructing user models from user usage and context data is provided where a personal interest graph for a user is constructing from interests of the user derived from usage data and situational data derived from one or more sensors of the electronic device. The nodes in the interest graph also contain information about a degree of user interest in the corresponding interest and a sentiment of the user at the time when the usage data suggests that the user expressed interest in the interest graph. The personal interest graph can be modified by annotating one or more nodes of the personal interest graph with influence information. Later, a current sentiment for the user can be determined by analyzing input from one more sensors on the electronic device, and a particular node can be located in the personal interest graph based on the information in the nodes.

A system and method for providing Value-Added Services (VAS) in an integrated telecommunications network having a packet-switched network portion (PSN) operable with Session Initiation Protocol (SIP). The integrated telecommunications network includes a SIPext SSP server, a trigger server, and a service node having a Service Logic Program (SLP) that is operable with Intelligent Network Application Protocol (INAP). The SIPext SSP and service nodes are provided with the capability to communicate using SIP-compliant messaging. New header fields are provided that specify operations to be performed by the service node with respect to a service. INAP service parametric data is also provided in the header fields in a sequential form. When a call is received in the SIPext SSP server for a user having a subscription for a VAS, it queries the user profile stored in the trigger server. If the user is subscribed for a service, a SIP request message is formulated based on the user profile, wherein appropriate headers are populated with relevant parametric information and call context data. The service node launches the SLP based on the information provided in the request message and sends a SIP response message to the SIPext SSP server with an instruction concerning the provisioning of the VAS. The SIPext SSP server, thereafter, takes an appropriate action based on the response message and any parametric information contained therein.

Embodiments of the present disclosure provide a method and system for implicitly authenticating a user to access controlled resources. The system first receives a request to access the controlled resource from a user. Then, the system determines whether the user request is inconsistent with regular user behavior by calculating a user behavior measure derived from historical contextual data of past user events. Next, responsive to the determined inconsistency of the user request, the system collects current contextual data of the user from one or more user devices without prompting the user to perform an explicit action for authentication. The system further updates the user behavior measure based on the collected current contextual data, and provides the updated user behavior measure to an access controller of the controlled resource to make an authentication decision based at least on the updated user behavior measure.
