    摘要： Methods and computer-storage media having computer-executable instructions embodied thereon that facilitate generating a machine-learned model for ranking search results using click-based data are provided. Data is referenced from user queries, which may include search results generated by general search engines and vertical search engines. A training set is generated from the search results and click-based judgments are associated with the search results in the training set. Based on click-based judgments, identifiable features are determined from the search results in a training set. Based on determining identifiable features in a training set, a rule set is generated for ranking subsequent search results.

    摘要： A focused random walk system produces samples of on-topic pages from a collection of hyper-linked pages such as Web pages. The focused random walk system utilizes a focused random walk to produce a focused sample, which is a random sample of Web pages focused on a topic. The focused random walk system uniformly samples pages iteratively, where each iteration follows a random link from a union of the in-links and out-links of a page. The system then classifies this randomly selected link to determine whether the page is on-topic. The random walk sampling process could comprise a hard-focus method that selects only on-topic pages at each step of the focused random walk, or a soft-focus method that allows limited divergence to off-topic pages.

    摘要： Disclosed are apparatus and methods for ranking lines of text. In one embodiment, an intent of a query is ascertained. A relevance of each one of a plurality of lines of text of a document is determined based upon the intent of the query, content of the query, and content of each of the plurality of lines of text. The plurality of lines of text may then be ranked according to the determined relevance of each of the plurality of lines of text.

    摘要： A fault-tolerant system for storage arrays has constraints on the number of data from which each redundancy value is computed. The fault-tolerant system has embodiments that are supported on small array sizes to arbitrarily large array sizes, and can tolerate a large number T of failures. Certain embodiments can tolerate many instances of more than T failures. The fault-tolerant system has efficient XOR-based encoding, recovery, and updating algorithms and has simple redundancy formulas. The fault-tolerant system has improved IO seek costs for certain multiple-element sequential host updates.

    摘要： A recovery enabling system for storage arrays is a high distance generalization of RAID-5 with optimal update complexity and near optimal storage efficiency. The recovery enabling system utilizes presets, data cells with known values that initialize the reconstruction process. The presets allow resolution of parity equations to reconstruct data when failures occur. In one embodiment, additional copies of the layout of the recovery enabling system are packed onto the same disks to minimize the effect of presets on storage efficiency without destroying the clean geometric construction of the recovery enabling system. The recovery enabling system has efficient XOR-based encoding, recovery, and updating algorithms for arbitrarily large distances, making the recovery enabling system an ideal candidate when storage-efficient reliable codes are required.

    摘要： In an effort to enhance computer user engagement with a search results page, systems and methods are presented which are configured to identify an entity as being the subject matter of a user's search query. If the entity is a known entity, i.e., entity information is stored in an entity store for the identified entity, a subset of entity attributes are identified and a representative entity attribute question is obtained for each of the attributes in the subset of entity attributes. The representative entity attribute questions are identified according to the probability that they are formed linguistically correct. The representative entity attribute questions are included in a search results page that is generated in response to the user's search query.
