  • Patent number: 12175188
    Abstract: This disclosure relates to a natural language processing technology, and provides a sentence paraphrase method and apparatus. The method includes: paraphrasing an input sentence by using a sentence paraphrase model, to generate a plurality of candidate paraphrased sentences; and determining a similarity between each of the plurality of candidate paraphrased sentences and the input sentence, to obtain an output sentence whose similarity to the input sentence is greater than or equal to a preset threshold, where each of a plurality of paraphrased sentence generators in the sentence paraphrase model includes one neural network, the plurality of paraphrased sentence generators are trained by using source information and similarity information as a first reward, and the paraphrased sentence is obtained by paraphrasing the training sentence by using the plurality of paraphrased sentence generators.

  • Patent number: 12073620
    Abstract: Systems, devices, media, and methods are presented for identifying emerging viewing patterns for visual media such as still images and videos. Emerging viewing patterns are identified by identifying visual tags for visual media viewed by users, selecting a subset of the tags by applying a taxonomy-based filter, generating pattern candidates from the subset, evaluating consumption metrics for each of the generated patterns, and ranking the generated pattern candidates responsive to the consumption metrics to identify emerging viewing patterns for the users.

  • Patent number: 11872168
    Abstract: A stair lift, including: a carrier portion, configured for carrying a person or an object; a lift portion, configured for moving relative to the carrier portion; and a driver mechanism, configured for inducing the relative movement. The carrier portion and the lift portion are connected and supported via a guide mechanism, and are configured for freely translating along an X-Z plane relative to each other. The driver mechanism includes a circulation moving mechanism, and the circulation moving mechanism includes a driving pin (moving member), configured for moving along a predetermined closed track under the driving of a single gear motor. The driving pin (moving member) is connected to the lift portion, such that the carrier portion and the lift portion are configured for moving relative to each other along the track, whereby enabling the stair lift to go upstairs or downstairs.
