摘要:
An apparatus and method are disclosed for verifying that a description of a network corresponds to communication paths of the network. The verification is accomplished by accessing data that represents of a plurality of logical links of the network. A determination is made whether each of the logical links correspond to a communication path of the network. This determination utilizes criteria, which includes: link data; adapter data; and connection data. Thereafter, an indication of whether the logical links correspond to communication paths of the network is provided. If each logical link does not have a corresponding communication path, additional information related to the reason for the non-correspondence may be provided.

Methods, systems and computer readable mediums are provided for indexing network resources. One method includes accessing, using one or more computer systems, a data store of menu items. The method further includes accessing identification information associated with one or more food providers from one or more data sources. One or more network resources are crawled based on the identification information to search for one or more menu items in the data store of menu items associated with corresponding ones of the food providers. Using the one or more computing systems, an index feed is generated, the index feed comprising the identification information of one or more of the food providers, and one or more menu items associated with the identification information of corresponding food providers based on the crawl and search.
摘要:
A method and system for inferring user attributes in a social networking system. The method includes maintaining a social graph comprising a plurality of nodes and a plurality of edges between the nodes. An unknown, incomplete, or inaccurate user attribute for a user is identified, and a plurality of probability lists are generated using a corresponding plurality of probability algorithms that utilize known user attributes and the social graph. The probability lists include a set of probability entries, each including a prediction we value for the unknown, incomplete, or inaccurate user attribute and a confidence score. Using the probability lists and a plurality of weights corresponding to the probability algorithms, an inferred user attribute value is generated and stored. The weights may be adjusted based upon learning the correct value of the unknown, incomplete, or inaccurate user attribute, and search results may be modified to include the user for search queries seeking information about the inferred user attribute.

Techniques are provided for the efficient location, processing, and retrieval of local product information derived from web pages generally locatable through form queries submitted to web pages often referred to as the “deep” or “hidden” web. In an embodiment, information such as product information and dealer-location information is located on a web page form such as a dealer-locator form. After location of a suitable web page form, editorial wrapping is performed to create an automated information extraction process. Using the automated information extractor, deep-web crawling is performed. A grid-based extraction of individual business records is performed, and matching and ingestion are performed in conjunction with a business listing database. Finally, metadata tags are added to entries in the business listing database. Metadata tags also may be added to entries in other databases.

Methods and apparatus are provided for incremental update of an XML tree defined from a recursive XML view of a relational database. A method comprises the steps of detecting at least one change to the relational database; providing one or more queries to the relational database to map the change to the relational database into changes to the XML tree, wherein at least one component of a definition of the one or more queries is executed a plurality of times in traversing a path through the XML tree; and applying the mapped change to the XML tree. A bud-cut method and a reduction approach are presented.
摘要:
A method and apparatus are provided for updating XML views of relational data. The present invention translates an update to an XML view of a relational database into update operations to be performed on the underlying relational database itself. The disclosed XML view update manager can perform updates in the context of an underlying relational database that serves the XML-based application, as well as traditional relational database management system (RDBMS) applications. Given a pre-existing underlying relational database schema and an XML view defined on it, the present invention provides a framework for generating update plans to perform an update without introducing side-effects to other parts of the view.
