Abstract: A method of unifying the different, device-specific and platform-specific access control lists (ACL) for different users and user groups in a home network. The home network has networked heterogeneous devices and hosting where a user is presented with a consistent, single view of ACL on home-wide users and user groups. Users in the home network, therefore, do not need to control ACL for device-specific users and user groups on each individual device. Instead, a user controls the home-wide ACL for home-wide users and user groups. The changes to home-wide ACL for home-wide users and user groups are propagated to individual devices. Further, changes on individual devices can be made to device-specific ACL for device-specific users and user groups. Such changes are subsequently propagated to the home-wide ACL for home-wide users and user groups.

Abstract: A definition of a set of context variables to be considered is received, wherein the context variables represent categories of situations in which the computer system can be. A definition of a set of activities to be considered is also received, wherein the activities represent activities that can be performed using the computer system. For each context variable to be considered, a definition of a set of states to be considered is received, wherein the states represent situations in which the computer system can be. For each context variable to be considered, a specification of first probability distributions for each corresponding state is received. For each context variable to be considered, for each activity to be considered, a specification of second probability distributions to represent the likelihood of the activity being performed in the corresponding context is received. Usage data is generated using the first second probability distributions.

Abstract: An input situation can be represented by at least a first context variable. Data that includes interest values for multiple context variables can be provided and obtained. The obtained data can include a first data pertaining to the input situation and a second data pertaining to one or more other situations. It can be determined whether the first context variable is associated with a discrete range of values or a continuous range of values. At least a portion of data pertaining to the situations can be determined to be proximate data when the first context variable is associated with a continuous range of values. Based on the input situation and the proximate data, an interest value for the first input situation can be determined as a prediction of the interest in the input situation.

Abstract: In one embodiment, data relating to usage patterns of the user is stored, wherein the data includes information as to items which were used and the context in which they were used. The data is then clustered into input clusters of data points. It is determined if there are any input clusters that are similar to each other. Similar clusters are merged if there are any input clusters similar to each other. Any non-merged input clusters are divided into split clusters if the split clusters would not be similar to each other. The determining, merging, and dividing are then repeated using the merged, divided, and remaining unmerged and undivided clusters as input clusters.

Abstract: Schema-driven XML parsing techniques allow an XML parser to optimize its parsing process by composing parse and to dynamically generate parsing code components based on XML schema definition for the targeted XML document. These techniques reduce the XML parsing time and reduce the memory requirement during parsing process. Further, a reconfigurable parser is provided which is guided during parsing of the XML document by XML element lexicographical information and state transition information extracted from a schema associated with the XML document. Pre-allocated element object pools may be provided based on the schema analysis to reduce the requirements for dynamic memory allocation and de-allocation operations.
