摘要： An improved system and method is provided for adaptively refreshing a web page. A base version of the web page may be partitioned into a collection of fragments. Then the collection of fragments may be compared with the corresponding fragments of a recent version of the web page to determine a divergence measurement of the difference between the base version and the recent version of the web page. The divergence measurement may be recorded in a change profile representing a change history of the web page that includes a sequence of numeric pairs indicating a time offset and a divergence measurement of the difference between a version of the web page at the time offset and a base version of the web page. The refresh period for the web page may be adjusted by applying an adaptive refresh policy using the divergence measurements recorded in the change profile.

摘要： A method and a system are provided for exploring a large textual data set via interactive aggregation. In one example, the method includes receiving the large textual data set and an original query template, building an index for the query template, wherein the building the index comprises ordering the index a particular way to optimize query time, receiving one or more bindings for the original query template, computing an answer to the original query template using the index and the one or more bindings, and anticipating one or more future queries that a user may submit and that are related to the original query template.

摘要： Methods, systems, and computer readable media comprising instructions for identifying needy queries for which additional responsive content is needed. A method comprises receiving a query comprising one or more terms and retrieving one or more content items identified as responsive to the query, the one or more content items ranked according to one or more ranking techniques. A score is generated for the one or more ranked content items identified as responsive to the query. A determination is thereafter made as to whether the query is needy based upon a comparison of the one or more scores associated with the one or more content items identified as responsive to the query and a needy query score threshold.

摘要： An improved system and method for crawl ordering of a web crawler by impact upon search results of a search engine is provided. Content-independent features of uncrawled web pages may be obtained, and the impact of uncrawled web pages may be estimated for queries of a workload using the content-independent features. The impact of uncrawled web pages may be estimated for queries by computing an expected impact score for uncrawled web pages that match needy queries. Query sketches may be created for a subset of the queries by computing an expected impact score for crawled web pages and uncrawled web pages matching the queries. Web pages may then be selected to fetch using a combined query-based estimate and query-independent estimate of the impact of fetching the web pages on search query results.

摘要翻译： 提供了一种改进的系统和方法，用于通过对搜索引擎的搜索结果的影响来爬取对网页爬虫的排序。 未获取的网页的内容无关的功能可能会被获取，并且可以使用内容无关的功能来估计未浏览的网页对工作负载的查询的影响。 未查询的网页的影响可以通过计算与有需要的查询匹配的未浏览的网页的预期影响分数来估计查询。 可以通过计算搜索的网页和匹配查询的未浏览的网页的预期影响分数来为查询的子集创建查询草图。 然后，可以使用基于查询的组合估计和对查询网页对搜索查询结果的影响的独立于查询的估计来选择网页。

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： The present invention, in an example embodiment, provides a special-purpose formal language and translator for the parallel processing of large databases in a distributed system. The special-purpose language has features of both a declarative programming language and a procedural programming language and supports the co-grouping of tables, each with an arbitrary alignment function, and the specification of procedural operations to be performed on the resulting co-groups. The language's translator translates a program in the language into optimized structured calls to an application programming interface for implementations of functionality related to the parallel processing of tasks over a distributed system. In an example embodiment, the application programming interface includes interfaces for MapReduce functionality, whose implementations are supplemented by the embodiment.
