  • Publication number: 20090182946
    Abstract: A method and system for optimizing resource usage in an information retrieval system. Meta information in query results describes data items identified by identifiers. A chunk of the identifiers and a set of meta information are loaded into a first cache and a second cache, respectively. A portion of the set of meta information is being viewed by a user. The portion describes a data item identified by an identifier included in the chunk and in a sub-chunk of identifiers that identifies data items described by the set of meta information. If a position of the identifier in the sub-chunk satisfies a first criterion, then a second set of meta information is preloaded into the second cache. If a position of the identifier in the chunk satisfies a second criterion, then a second chunk of the identifiers is preloaded into the first cache.

  • Patent number: 7483890
    Abstract: A tagging tree that defines a hierarchical output data structure and relational database query operations that retrieve the data to be included in each hierarchical section is accepted and processed. A query optimizer analyzes the tagging tree to determine database query operations that can be combined into a single query command. An outer-union query command is generated to allow efficient combination of multiple query commands, some of which are predicates to others. The tagging tree is modified to replace the database queries that were combined into the outer-union query to extract data from the results set produced by the outer-union query as opposed to submitting queries to the database manager. The optimized queries can be reused an arbitrary number of times to leverage the optimizing resources that were used in their creation.

  • Patent number: 7454469
    Abstract: A framework for creating instant messaging Bots that autonomously operate within an instant messaging sessions to respond to requests from other user(s) or Bot(s). Bot operation is defined by a state machine with one or more states that are described in XML documents. These XML documents abide by the grammar of a Bot Transition Definition Language (BTDL) that is defined in an XML schema. A Bot developer creates a state transition diagram via a Graphical User Interface. The state transition diagram defines states, transitions between states, and conditions for each of those state transitions and methods to be performed upon each state transition. An XML document that conforms to BTDL format is created from the state transition definition diagram. Both stateful and stateless Bots are defined using XML documents abiding to a BTDL format. A runtime environment implements the Bots, accepts runtime inputs and generates responses.

  • Patent number: 7409634
    Abstract: The system for end-to-end content publishing using XML with an object dependency graph is based on the following two design principles: First, separation of content and style: Information stored in the content management system is independent on how it is going to be presented. The presentation style is encapsulated elsewhere and can be used to customize the look and feel based on the end-user preferences as well as the delivery methods and devices. Second, reusability of information content: By encapsulating common information in fragments and subfragments and making these fragments insertable in other fragments, thereby avoid scattering and duplication of information. This enables a user to restrict the edit operations to a limited number of relevant fragments, to affect global changes. In addition, the present invention provides data consistency and data integrity in the content management.

  • Patent number: 7284012
    Abstract: A system selects a plurality of attributes common to objects being compared and defines at least one value space for each selected attribute. Each selected attribute can have a value space that is different from a value space of the same attribute associated with a different object. The system defines an ordering system for each value space including selecting whether the value space consists of non-ordered values, partially ordered values, or fully ordered values. An objective function is defined for each ordering system and the objective function maps a pair of values of a value space to a number value. The system normalizes each objective function and defines a mapping from the plurality of objective functions to a first general objective function.
