摘要:
A method and system for expanding a document set as a search data source in the field of business related search. The present invention provides a method of expanding a seed document in a seed document set. The method includes identifying one or more entity words of the seed document; identifying one or more topic words identifying one or more topic words related to the based entity word in the seed document where the entity word is located; forming an entity word-topic word pair from each identified topic word and the entity word on the basis of which each topic word is identified; and obtaining one or more expanded documents through web by taking the entity word and topic word in the each entity word-topic word pair as key words at the same time. A system for executing the above method is also provided.

A method and system for filtering a candidate document in a candidate document set are provided. The method includes receiving one or more entity word—topic word pairs and identifying one or more entity words of the candidate document and topic words. The method also includes determining whether to add the candidate document into a filtered document set using the entity words and topic words in the given entity word—topic word pairs and the identified entity words and topic words in the candidate document. The method further includes adding the candidate document into a filtered document set in response to determining that the candidate document should be added into the filtered document set.

A method, system, and computer program product for providing caller identification services to an Internet Protocol-enabled device are provided. The method includes receiving a communication request from a caller device over a voice network, the communication request including a caller party number, mapping a called party number to an Internet Protocol-enabled device address of a called party, and sending the caller party number to the Internet Protocol-enabled device address corresponding to the called party number.
摘要:
A method for identifier retrieval. The method can include the steps of: extracting candidate identifiers from a data source according to a source identifier; obtaining a profile of the source identifier and profiles of the candidate identifiers from the data source; and selecting a target identifier associated with the source identifier from the candidate identifiers according to the profile of the source identifier and the profiles of the candidate identifiers. The method may efficiently, accurately and rapidly find a target identifier associated with a source identifier.

Methods and apparatuses to detect spectrum inversion based on estimated frequency offset in carrier signal. In one embodiment, a receiver includes an I/Q swap module to output an in-phase component and a quadrature-phase component; a frequency offset estimator to determine an offset in carry frequency of the in-phase and quadrature-phase components; and a spectrum inversion detector coupled to the frequency offset estimator and the I/Q swap module. The spectrum inversion detector is configured to signal the I/Q swap module to swap the in-phase component and the quadrature-phase component when an absolute value of the offset in carry frequency is above a predetermined threshold.

Methods for removing halogen-containing residues from a substrate are provided. By combining the heat-up and plasma abatement steps, the manufacturing throughput can be improved. Further, by appropriately controlling the pressure in the abatement chamber, the removal efficiency can be improved as well.

The present disclosure relates approaches that may be used to manage research assets, such as equipment and consumable items. In certain implementations, asset information from multiple input sources is stored in a database or other mass storage device and may be used to provide a report of the real time condition of any individual research asset. In further implementations, the information may be used to provide indications or reminders associated with an individual research asset, such as maintenance reminders.

A dual-energy material identification method and system with under-sampling is disclosed. A CT image of the object is obtained by using the CT image reconstruction method, while the dual-energy projections are under-sampled to obtain a few samples. Photoelectric coefficient integral and Compton coefficient integral are computed from these dual-energy projection data. The CT image is segmented into regions with image processing technique, and the regions are labeled. The length by which a few dual-energy rays crosses each labeled region is computed, and an equation system is established with dual-energy preprocessing dual-effect decomposition reconstruction method to compute Photoelectric coefficient and Compton coefficient, and then atomic number and electron density of material in each region are computed. The material of the object can be identified with the atomic number.
摘要:
The present invention discloses a method for performing CT imaging on a region of interest of an object under examination, comprising: acquiring the CT projection data of the region of interest; acquiring the CT projection data of region B; selecting a group of PI line segments covering the region of interest, and calculating the reconstruction image value for each PI line segment in the group; and combining the reconstruction image values in all the PI line segments to obtain the image of the region of interest. The present invention further discloses a CT imaging device using this method and a data processor therein. Since the 2D/3D slice image of the region of interest can be exactly reconstructed and obtained as long as the X-ray beam covers the region of interest and the region B, it is possible to use a small-sized detector to perform CT imaging on the region of interest at any position of a large-sized object, which reduces to a great extent the radiation dose of the X-ray during the CT scanning.
