摘要： A method of searching that comprises receiving a user query from a user. After receiving the user query, the method performs a search based on the user query to produce results that are ranked. The results comprise references to entities. The method contacts the entities to determine whether entities in the results desire to change their rank in the results, and charges entities that increase their rank. After charging the entities and changing rankings of the results, the method reports the results with changed rankings to the user, and credits entities that decrease their rank.

摘要： An improved system and method is provided for characterizing a web page using multiple anchor sets of web pages. To do so, web pages in a collection of unknown web pages may be characterized using known anchor sets of web pages with different characterizations that may be linked to the collection of unknown web pages. A direction and method may be selected for propagating a probability distribution between vertices of a graph representing the collection of web pages and vertices of the anchor sets representing the anchor sets of web pages. Methods for propagating the probability distribution in a forward, backward or bidirectional direction are provided. Various quality measures of the characterization of the vertices are provided using the propagated probability distribution. These various quality measures may be paired and combined in different ways to provide a characterization of the vertices representing the unknown web pages.

摘要： An improved system and method is provided for searching a collection of objects that may be located in hierarchies of auxiliary information for retrieval of response objects. A framework to perform a generalization search in hierarchies may be used to generalize a search by moving up to a higher level in a hierarchy of taxonomies or to specialize a search by moving down to a lower level in the hierarchy of taxonomies. Once the system may decide to enumerate response objects at a particular level of generalization, a budgeted generalization search may be used for enumerating a set of response objects within a budgeted cost.
摘要翻译：提供了一种改进的系统和方法，用于搜索可能位于用于检索响应对象的辅助信息的层级中的对象的集合。在层次结构中执行泛化搜索的框架可以用于通过在分类法的层次结构中移动到更高级别来推广搜索，或者通过向下移动到分类法层级中的较低级别来专门化搜索。一旦系统可以决定在特定的泛化级别枚举响应对象，则可以使用预算的泛化搜索来枚举在预算成本内的一组响应对象。

摘要： A sender computer maps a randomized concatenation of a message μ to a point “x” in space using a function that renders it infeasible that a second message can be mapped nearby the message μ. The function can be a collision intractable or non-collision intractable function that maps the message to a point “x” on a widely-spaced grid, or the function can map the message to a point “x” of an auxiliary lattice. In either case, the sender computer, using a short basis (essentially, the private key) of a key lattice finds a lattice point “y” that is nearby the message point “x”, and then at least the points “x”, “y”, and message are sent to a receiver computer. To verity the signature, the receiver computer simply verifies that “y” is part of the lattice using a long basis (essentially, the public key), and that the distance between “x” and “y” is less than a predetermined distance, without being able or having to know how the lattice point “y” was obtained by the sender computer.

摘要： A system and method for aggregating rankings from a plurality of ranking sources to generate a maximally consistent ranking by minimizing a distance measure. The ranking sources may be search engines executing queries on web pages that have been deliberately modified to cause an incorrect estimate of their relevance. The invention supports combining partial rankings.

摘要： A social environment is provided by creating an object in response to recognition of an entity in a portion of web content, wherein the object represents the entity, the object is associated with a type selected from a set of types, and the type is associated with a schema selected from a set of schemas, where the social environment includes a set of objects including the object, wherein the objects are instances of corresponding types in a rich system of predefined types, the schemas are associated with the types, metadata is associated with the objects, and there is at least one relationship between at least two objects selected from the set of objects, where the set of objects and the metadata are extensible, such that extensions provided by a first user are available for use by a second user. In one example, metadata provided by a first user is only available to a second user having a relationship with the first user.

摘要： Disclosed are methods and apparatus for matching sets of text to objects are disclosed. In accordance with one embodiment, a set of text is obtained. For instance, the set of text may include a review. A numerical value is determined for each of a plurality of objects, where the numerical value indicates a likelihood that the corresponding one of the plurality of objects is a subject of the set of text. Each of the plurality of objects has an object type defined by a set of one or more attributes, each of the set of one or more attributes having associated therewith a corresponding set of one or more parameters, wherein the numerical value is determined using the set of text and a value of each of the set of one or more parameters for each of the set of one or more attributes. One of the plurality of objects that is most likely to be the subject of the set of text is identified based upon the numerical value that has been determined for each of the plurality of objects.
