摘要:
A method is provided to ubiquitously promote products or services provided by a plurality of advertisers across a plurality of content-based applications. The method may include receiving data from the plurality of advertisers describing the products or services provided by the plurality of advertisers. The received data is stored in an advertisement database where a user may subsequently query the advertisement database to locate data promoting a product or service. Additionally, terms and payment data are extracted from the received advertisement data to efficiently promote the products or services provided by the advertiser across the plurality of content-based applications.
摘要:
A method and system for generating a projection matrix for projecting data from a high dimensional space to a low dimensional space. The system establishes an objective function based on a maximum margin criterion matrix. The system then provides data samples that are in the high dimensional space and have a class. For each data sample, the system incrementally derives leading eigenvectors of the maximum margin criterion matrix based on the derivation of the leading eigenvectors of the last data sample. The derived eigenvectors compose the projection matrix, which can be used to project data samples in a high dimensional space into a low dimensional space.
摘要:
A method is presented comprising assigning each of a plurality of segments comprising a received corpus to a node in a data structure denoting dependencies between nodes, and calculating a transitional probability between each of the nodes in the data structure.
摘要:
A method of forming at least one single crystal of a Group III metal nitride. The method includes the steps of: providing a flux material and a source material comprising at least one Group III metal selected from the group consisting of aluminum, indium, and gallium, to a reaction vessel; sealing the reaction vessel; heating the reaction vessel to a predetermined temperature and applying a predetermined pressure to the vessel. The pressure is sufficient to suppress decomposition of the Group III metal nitride at the temperature. Group III metal nitrides, as well as electronic devices having a Group III metal nitride substrate formed by the method are also disclosed.
摘要:
A non-volatile SRAM memory comprising a plurality of memory cells, each memory cell including a SRAM memory cell portion and a ferroelectric memory cell portion including a ferroelectric element, the ferroelectric memory cell portion including a switch system for permitting the ferroelectric element to be isolated from the ferroelectric elements in all other memory cells.
摘要:
A system for calculating the importance of web pages is provided. The web pages are organized hierarchically into collections. The system calculates the importance of each collection based on inter-collection links from a web page in one collection to a web page in another collection. The system then calculates the importance of web pages in the collections with a high calculated importance based on links between the web pages in those collections using, for example, a conventional page rank algorithm. The system may also calculate the importance of web pages in each collection with a low calculated importance separately based on the links between the web pages in the collection using, for example, a conventional page rank algorithm.
摘要:
A method and system for clustering documents based on generalized sentence patterns of the topics of the documents is provided. A generalized sentence patterns (“GSP”) system identifies a “sentence” that describes the topic of a document. To cluster documents, the GSP system generates a “generalized sentence” form of the sentence that describes the topic of each document. The generalized sentence is an abstraction of the words of the sentence. The GSP system identifies clusters of documents based on the patterns of their generalized sentences. The GSP system clusters documents when the generalized sentence representations of their topics have a similar pattern.
摘要:
The disclosed subject matter improves iterative results of content-based image retrieval (CBIR) using a bigram model to correlate relevance feedback. Specifically, multiple images are received responsive to multiple image search sessions. Relevance feedback is used to determine whether the received images are semantically relevant. A respective semantic correlation between each of at least one pair of the images is then estimated using respective bigram frequencies. The bigram frequencies are based on multiple search sessions in which each image of a pair of images is semantically relevant.
