Abstract: Disclosed is a brand value evaluation method, comprising: acquiring a brand set to be processed containing a plurality of brands to be processed; collecting evaluation data corresponding to the brand set to be processed, and identifying the brand set to be processed based on the evaluation data to obtain a reputation degree and a volume of each brand to be processed in the brand set to be processed; acquiring a brand to be evaluated, and judging whether the brand to be evaluated exists in the brand set to be processed; when it exists, determining the reputation degree and volume of the brand to be evaluated as a target reputation degree and a target volume; determining a value for the brand to be evaluated according to the reputation degree of each brand to be processed, the volume of each brand to be processed, the target reputation degree and the target volume.

Abstract: The application relates to the technical field of information extraction, in particular to a keyword extraction method. The method comprises: acquiring a text to be processed, and performing word segmentation on the text to be processed to obtain at least one word segmentation result; performing entity recognition on all the word segmentation results through a preset entity recognition model to obtain at least one entity recognition result; performing part-of-speech tagging on all the entity recognition results to obtain part-of-speech tagging results; scoring all the part-of-speech tagging results through a preset scoring metric to obtain score values; filtering all the part-of-speech tagging results based on all the score values to obtain at least one target word; running word co-occurrence statistics on all the target words to obtain word co-occurrence values, and performing keyword extraction on all the target words based on the word co-occurrence values to obtain keyword extraction results.

Abstract: Method for installing reactor coolant loop (RCL) piping of a reactor coolant system (RCS) system in a pressurized water reactor (PWR) nuclear power plant by positioning the reactor vessel, steam generator, or both, into position after attaching one or more coolant pumps, surveying coolant loop piping and a plurality of nozzles on the reactor vessel, the steam generator and coolant pump casing, or a combination thereof, with a precise measurement and 3D modeling technology for positioning data, then performing weld prep machining for the coolant loop piping on the reactor vessel side, and machining for the coolant loop piping on the steam generator side and coolant pump side based on the positioning data, and installing temporary supports for coolant loop piping and finishing the fit-up and welding between the coolant loop piping and the reactor vessel, steam generator, and each coolant pump.
