20130343459 | METHOD AND APPARATUS FOR VIDEO CODING - There is provided a method, apparatus and computer program product. In some embodiments an uncompressed picture is encoded into a coded picture comprising a slice; determining a list of prediction reference candidates for the slice in one or more temporal reference pictures; associating each prediction reference candidate in the list with a reference index; and examining if the prediction reference candidate associated with a first reference index is available for temporal motion vector prediction for the slice. If the prediction reference candidate with the first reference index is not available for temporal motion vector prediction for the slice, examining if the list comprises another prediction reference candidate associated with another reference index. If the list comprises another prediction reference candidate associated with another reference index, providing the reference index associated with the another prediction reference candidate in a syntax element at a slice level or at a higher level. | 12-26-2013 |
20140085415 | METHOD AND APPARATUS FOR VIDEO CODING - There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments the method for encoding comprises obtaining samples of a video signal for encoding a first layer representation of the video signal and a second layer representation of the video signal. An encoded first layer representation of the video signal is used as a prediction reference in the encoding of the second layer representation of the video signal. It is evaluated whether to use filtering in the encoding of the second layer representation. If the evaluation indicates to use filtering in the encoding of the second layer representation, the method further comprises filtering the encoded first layer representation; and using the filtered encoded first layer representation as the prediction reference in the encoding of the second layer representation of the video signal. | 03-27-2014 |

20110173222 | DATA VALUE REPLACEMENT IN A DATABASE - An exemplary embodiment of the present invention provides a method of correcting data in a database table. The method includes processing a database table to identify an incorrect data field value of a data field in the database table. The method also includes obtaining a search keyword from the database table that corresponds with the incorrect data field value. The method also includes generating a regular expression based, at least in part, on a data field type corresponding with the incorrect data field value. The method also includes searching a secondary source using the search keyword and the regular expression to identify a target data value. The method also includes replacing the incorrect value in the database table with the target data value. | 07-14-2011 |
20110178974 | METHOD AND SYSTEM FOR ANALYZING DATA STORED IN A DATABASE - One embodiments of the present invention is directed to a data-analysis system, implemented as one or more electronic computers that execute one or more computer programs. The data-analysis system includes a metadata-extraction component that extracts indications of data entities and relationships between data entities from data stored on one or more electronic-memory and mass-storage devices, a relationship-inference component that analyzes the data to infer additional relationships between data entities, a context-determination component that determines one or more contexts within which the data is analyzed, and a navigational analysis tool, displayed on a computer device, that provides an interface that allows for navigation between relationship-interconnected data entities within each of one or more contexts, for viewing representations of data entities and relationships, and for editing and updating the relationships. | 07-21-2011 |
20110270655 | Offer conversion - A source offer and offer parameters regarding the source offer are received. Specifications for one or more of a number of conversion parameters are also received. The source offer is converted to a target offer, based on the offer parameters and the conversion parameters specified. Where the source offer is an incremental offer, the target offer is a cumulative offer. Where the source offer is a cumulative offer, the target offer is an incremental offer. In an incremental offer, when a volume reaches a volume threshold, a price decreases by a corresponding price discount for the volume above the volume threshold, but the price does not decrease for the volume below the volume threshold. In a cumulative offer, when the volume reaches at the volume threshold, the price decreases by the corresponding price discount for the volume both below and above the volume threshold. | 11-03-2011 |

A method for determining offer terms from text can include mapping keywords to a domain of a procurement event, and receiving, to a computing device, an offer text associated with the procurement event. Event-specific entities are identified, by the computing device, in the offer text. The computing device determines the domain of the procurement event from the identified event-specific entities, and using the mapped keywords corresponding to the determined domain, determines offer components from the offer text, extracts offer parameters from the offer text, and constructs the offer structure using the identified event-specific entities, derived offer components, and extracted offer parameters. | 03-29-2012 |
