20110138264 | Verification Of Data Stream Computations Using Third-Party-Supplied Annotations - A third party that performs data stream computation is requested to return not only the solution to the computation, but also “annotations” to the original data stream. The annotations are then used by the data owner (in actuality, a “verifier” associated with the data owner) to check the results of the third party's computations. As implemented, the verifier combines the annotations with the original data, performs some computations, and is then assured of the correctness of the provided solution. The cost of verification is significantly lower to the data owner than the cost of fully processing the data “in house”. | 06-09-2011 |
20120159500 | VALIDATION OF PRIORITY QUEUE PROCESSING - A method for validating outsourced processing of a priority queue includes configuring a verifier for independent, single-pass processing of priority queue operations that include insertion operations and extraction operations and priorities associated with each operation. The verifier may be configured to validate N operations using a memory space having a size that is proportional to the square root of N using an algorithm to buffer the operations as a series of R epochs. Extractions associated with each individual epoch may be monitored using arrays Y and Z. Insertions for the epoch k may monitored using arrays X and Z. The processing of the priority queue operations may be verified based on the equality or inequality of the arrays X, Y, and Z. Hashed values for the arrays may be used to test their equality to conserve storage requirements. | 06-21-2012 |

20080306908 | Finding Related Entities For Search Queries - Architecture for finding related entities for web search queries. An extraction component takes a document as input and outputs all the mentions (or occurrences) of named entities such as names of people, organizations, locations, and products in the document, as well as entity metadata. An indexing component takes a document identifier (docID) and the set of mentions of named entities and, stores and indexes the information for retrieval. A document-based search component takes a keyword query and returns the docIDs of the top documents matching with the query. A retrieval component takes a docID as input, accesses the information stored by the indexing component and returns the set of mentions of named entities in the document. This information is then passed to an entity scoring and thresholding component that computes an aggregate score of each entity and selects the entities to return to the user. | 12-11-2008 |

20110320446 | Pushing Search Query Constraints Into Information Retrieval Processing - This patent application relates to interval-based information retrieval (IR) search techniques for efficiently and correctly answering keyword search queries. In some embodiments, a range of information-containing blocks for a search query can be identified. Each of these blocks, and thus the range, can include document identifiers that identify individual corresponding documents that contain a term found in the search query. From the range, a subrange(s) having a smaller number of blocks than the range can be selected. This can be accomplished without decompressing the blocks by partitioning the range into intervals and evaluating the intervals. The smaller number of blocks in the subranges(s) can then be decompressed and processed to identify a doc ID(s) and thus document(s) that satisfies the query. | 12-29-2011 |

20150227589 | SEMANTIC MATCHING AND ANNOTATION OF ATTRIBUTES - Techniques and constructs to facilitate semantic matching and automated annotation (SMA) of attributes can take entity names and a keyword describing an attribute associated with the named entities as input and leverage a corpus of data such as data from tables, which can include HTML web tables, to automatically populate values associated with the named entities for the attribute. The constructs enable accurate SMA of attributes, such as attributes that relate to the entity and include numeric values in a different unit than the query, in a different scale than the query, and/or reflecting a time different from that of the query. An entity augmentation application programming interface (API) may be used to accept queries that include numeric criteria, parameters, or arguments, including query attributes represented by numeric values, which may be in different units or scales, and attributes represented by numeric values that can vary by time. | 08-13-2015 |
20150310073 | FINDING PATTERNS IN A KNOWLEDGE BASE TO COMPOSE TABLE ANSWERS - In general, the knowledge base table composer embodiments described herein provide table answers to keyword queries against one or more knowledge bases. Highly relevant patterns in a knowledge base are found for user-given keyword queries. These patterns are used to compose table answers. To this end, a knowledge base is modeled as a directed graph called a knowledge graph, where nodes represent entities in the knowledge base and edges represent the relationships among them. Each node/edge is labeled with a type and text. A pattern that is an aggregation of subtrees which contain all keywords in the texts and have the same structure and types on node/edges is sought.

20130117185 | Method for conducting a transaction between a merchant site and a customer's electronic device without exposing payment information to a server-side application of the merchant site - A transaction is conducted between a merchant site and a customer's electronic device using a payment processor. The merchant site is associated with a client-side application and a server-side application. The client-side application executes on the customer's electronic device. The client-side application electronically sends payment information retrieved from the customer's electronic device to the payment processor. The client-side application does not send the payment information to the server-side application. The payment processor creates a token from the payment information sent by the client-side application. The token functions as a proxy for the payment information. The payment processor electronically sends the token to the client-side application. The client-side application electronically sends the token to the server-side application for use by the server-side application in conducting the transaction. The payment information can thus be used by the server-side application via the token without the server-side application being exposed to the payment information. | 05-09-2013 |
