  • Patent number: 12259917
    Abstract: A method of retrieving a document according to an embodiment of the present application includes: acquiring a user retrieval query; calculating a user inquiry vector in a unit of sentence from the user retrieval query and acquiring a first document candidate group based on similarity between the calculated user inquiry vector and an embedding vector of a document stored in a retrieval database; acquiring a second document candidate group based on similarity between a text included in the user retrieval query and a text of the document stored in the retrieval database; and determining a summarization target document based on the first document candidate group and the second document candidate group.

  • Patent number: 12236622
    Abstract: An image signal processor includes a statistic data generating unit for receiving an image signal from an external device, an image processing unit for receiving the image signal, and a direct memory access (DMA) module connected to the statistic data generating unit and the image processing unit. The statistic data generating unit performs first image pre-processing on the image signal and generates first statistic data based on the image signal subjected to the first image pre-processing. The DMA module stores the first statistic data therein and provides the stored first statistic data to the image processing unit. The image processing unit performs second image pre-processing on the image signal and performs image processing on the image signal based on the first statistic data.

  • Publication number: 20090176002
    Abstract: The method of the present invention involves performing the deodorization step before the hydrogenation step and carrying out the hydrogen addition reaction under mild conditions effective to prevent the hardening of edible oil and trans fatty acid production, resulting in the production of processed edible oil having an enriched buttery flavor that is 100-fold stronger than the conventional hydrogenated oil with no unpleasant smell and a very low trans-fatty acid content. Further, the processed edible oil prepared according to the method of the present invention, even with the addition of only a small amount to conventional edible oil, food and feed products, is capable of providing an enriched buttery flavor without increasing the trans-fatty acid content or unpleasant smell and is, thus, useful as a substitute oil for hydrogenated vegetable oil.

  • Publication number: 20060240174
    Abstract: The present invention relates to a method for the reduction of acrylamide formation, in which a nucleophilic a-amino group (—NH2) is protonated and converted into a non-nucleophilic amine (—NH3+). The inventive method has the effect of allowing the formation of acrylamide to be highly reduced by simple treatment with a pH-lowering agent. Particularly, when applied to foods or foods ingredients, the inventive method has the effect of allowing the formation of acrylamide to be highly reduced without affecting the flavor and color of the foods or foods ingredients.
